Aspiring to Flourish in Miles-Tianjin Strives to Build a World-Class Smart Port and Green Port

Release time:

2023-11-10 16:47

Haimen looks back at thousands of peaks and surges, and the port opens thousands of miles. When the first ray of sunshine shines on the sea in the morning, Tianjin Port once again opened a day of endless flow.

Since the 18th National Congress of the Communist Party of China, Tianjin has thoroughly implemented the important directive spirit of General Secretary Xi Jinping "We must aim at thousands of miles, strive to build a world-class smart port and green port, and better serve the coordinated development of Beijing, Tianjin and Hebei and the joint construction of the'Belt and Road'". Work hard to accelerate the advancement of the world

The construction of a first-class green smart hub port, actively promote the construction of Tianjin's northern international shipping hub, build a high-level Beijing-Tianjin-Hebei "maritime gateway" hub, build a high-quality "Belt and Road" open platform, serve the national strategy in precise positioning, and transform and upgrade Integrate into the new development pattern.

From breaking ground to spring tide, from surging to sailing, Tianjin, facing the Bohai Sea in the east, is prospering because of the port and Changxing because of the port.

From a difficult start to a wise leader, from the radiation to the world, Tianjin Port, which is backed by Tianjin City, is thriving and prosperous.

Change "wisdom" to create "quality" to change wisdom port self-reliance and self-improvement

Driving to the intelligent container terminal in section c of Tianjin port's northern Xinjiang port area, between the blue sea and the blue sky, the colorful terminal has already started the "efficient operation mode" -12 automatic quay bridges stand, loading and unloading containers efficiently from giant ships from all over the world, 76 intelligent horizontal transport robots shuttle back and forth, and 42 automatic field bridges operate freely......

On October 17, 2021, the world's first "smart zero carbon" terminal was put into operation in Tianjin. It took several years to do things abroad. Tianjin Port only took 1 year and 9 months to achieve a number of global initiatives, won the 2022 World Mobile Conference Global Mobile Award, and led the world's port intelligence with a new model. Upgrade trend.

Even in the face of the complex and volatile international economic situation and the adverse effects of repeated epidemics in many places in China, the terminal is still constantly refreshing its operational efficiency, maintaining a contrarian growth of more than 20% per month in throughput this year.

However, a few years ago, it was only an idle freight yard in the port area. At that time, Tianjin Port was still developing large-scale, alliance and automation in the port.

In the trend of continuous exploration, accelerate the running in the transformation of development mode, optimize the structure of the layout of the "rush test" on the road.

Aspiring in thousands of miles, bravely climbing the peak, no longer pursuing the extensive "volume effect" of the century-old port surged with "wisdom" to create "quality" change of the wave of the times, in the rotation of the sun and the moon, played a song to the sea to the strong high-quality development of the new movement.

"Over the years, we have kept in mind the earnest instructions of General Secretary Xi Jinping, actively integrated into the construction of' Tianjin Smart Harbour', continuously strengthened the deep integration of new generation information technologies such as 5G, Internet, big data, artificial intelligence and block chain with various fields of ports, and contributed to the 'Tianjin Project' for the intelligent upgrading of global ports '." Wang Xuan, general manager of Tianjin Port Group Kexin Facilities Department, said.

From the completion of the automation upgrade of the world's first single container terminal full yard rail bridge to the full completion of the world's first traditional container terminal full process automation upgrade project; From the launch of services such as the intelligent platform for port collection and dredging, the business model of "ship-side direct lifting" and "arrival direct loading" has been expanded, and the direct arrival rate of foreign trade container ships has reached 96%, operational efficiency is at the leading level in the world... Leading and exemplary "innovations" and "firsts" have been born one after another. The achievements of Tianjin Port's smart port construction have attracted the attention of the world, and the gold-lettered signboard of "Tianjin Port Efficiency" has been launched around the world.

In 2021, to overcome the impact of the epidemic and poor international shipping, Tianjin Port completed a cargo throughput of 0.529 billion tons, an increase of 5.3 percent year-on-year; container throughput reached 20.27 million million TEUs, an increase of 10.4 percent year-on-year. In particular, container throughput has increased by nearly 70% compared to 10 years ago.

In the first eight months of this year, Tianjin Port Group once again achieved "double growth" against the trend, completing a cargo throughput of 0.32 billion tons, an increase of 3.1 percent over the same period last year, and a container throughput of 14.53 million TEUs, an increase of 4.1 percent over the same period last year.

Zhang Baoyi, president of the Tianjin Sociological Society, pointed out that to maximize the powerful role of the core strategic resources of Tianjin Port, Tianjin's role and actions in actively integrating into the national strategy, stabilizing the national economic market, and making every effort to build a domestic and international "double cycle" strategic fulcrum It is even more exciting.

Develop Green Port with Low Carbon

Walking into an inconspicuous building at the Tianjin Port Coal Terminal, behind an automatic door with a strong sense of science fiction, there is the intelligent centralized control center of the coal terminal. With the click of the mouse and the coordination of the walkie-talkie, the coal will be automatically loaded and unloaded.

"In 2017, Tianjin Port comprehensively promoted the 'revolution to iron' and 'scattered to change', we carried out intelligent transformation of the dock, and invested nearly 0.2 billion yuan to complete the dumper pit spray system, along the belt counterweight area closed, windproof network construction and other environmental protection upgrades. Today, the coal off the ship all the way 'closed' can be loaded on the train." Tianjin Port Coal Terminal Company Deputy General Manager Guan Kun said.

Tianjin Port is a big coal port. Once upon a time, the operation here was open and dusty, and the coal transport vehicles were often "white cars coming in and black cars going out". Today, it is still an important port for "transporting coal from the north to the south" in China, but it has long been "transporting coal without coal", and the clear water reflects the blue sky.

According to Chu Bin, chairman of Tianjin Port Group, green is the true color of the port and the background color of port development. "over the years, we have thoroughly implemented the spirit of General Secretary Xi Jinping's inspection of important instructions and the decisions and arrangements of the municipal party committee and municipal government, made every effort to build an intrinsically safe and green development model, continued to promote the construction of land-sea two-way green ports, and actively built a national demonstration green port."

Thousands of sails are racing with great momentum.

Aim at the green, the sword refers to "double carbon". In the past few years, a series of top-level designs have been introduced one by one; clean energy technologies have been applied one after another; special railway lines have been put into use one after another; the intelligent transformation of coal, ore and other terminals has changed the appearance of traditional bulk cargo transportation......

Today, Tianjin Port is actively building a double demonstration port of "revolution to rail + scattered collection". The proportion of iron ore railway transportation reaches 65%, which is in the forefront of ports in the country. The use of shore power for 100 per cent of the berthing of ships in its own port, and the utilization rate of low-sulfur oil for ships reached 100 per cent. The first domestic port ecological environment atmospheric intelligent monitoring platform to achieve port-wide coverage. The world's first zero-carbon terminal smart green energy system has been connected to the grid for nearly 9 months, with a cumulative power generation of about 17.5 million kWh, reducing carbon dioxide emissions by more than 18000 tons, and saving more than 5200 tons of standard coal.

Almost every day, Zhang Zhiqiang, an iron ore receiver of Rongcheng Group, and his colleagues wait for the special train from Tianjin Port. "At present, most of the ore transported from Tianjin Port directly into the factory by rail, almost 4 trains a day. Last August, the city's bulk hydrogen container truck application pilot landed between Rongcheng Group and Tianjin Port. It is expected that the railway will reduce the number of cars transported by nearly 20000 times per year, and the hydrogen energy heavy truck will be put into use on the first anniversary to reduce carbon dioxide emissions by 633.7 tons." Rongcheng group related responsible person said.

A carbon emission intensity chart of Tianjin Port since 2012 shows that in the past 10 years, the container throughput of Tianjin Port has increased by nearly 70%, but the carbon emission intensity has decreased by 16%. The fruitful results of the construction of a green port in Tianjin Port are self-evident.

Hub to promote coordination of the world port Jintong world

One day not long ago, just after midnight, the lights were brightly lit on the Eurasian International Container Terminal of Tianjin Port. The 27 containers of Shanghai Puhai Shipping Company were neatly stacked on a foreign trade container ship named "Mediterranean Mundra. As a whistle pierced the night sky, the freighter sailed out overnight. "This batch of goods is glass products, produced in Hebei Province, and will be exported to South Korea, Chile, Brazil and other places after transit through Tianjin Port." Li Meng, deputy manager of the terminal operations department, said.

At the same time, two more Bohai Rim feeder freighters sailed to the Beijiang Port area of Tianjin Port one after another, berthing at the Tianjin Port Container Terminal and the Tianjin Port Alliance International Container Terminal, the operation started, the vehicles shuttled, and the Tianjin Port in the night was as busy as day.

The seemingly ordinary cargo turnover shows the fruitful results of Tianjin's role as a port hub, serving Beijing, Tianjin and Hebei and connecting the world.

"When inspecting the Tianjin Port Terminal, General Secretary Xi Jinping emphasized that better serving the coordinated development of Beijing-Tianjin-Hebei and the joint construction of the'Belt and Road' has enabled Tianjin Port to find a new direction in the national strategy." Chu Bin said.

Give full play to the resource endowment, actively practice the strategic mission of serving the country, Tianjin Port takes the initiative to benchmark the positioning of Tianjin's northern international shipping hub, and makes every effort to build an internal and external hub port.

Sea direction, integrating global resources, focusing on the development of container routes, promoting the misplaced development of Tianjin and Hebei ports, and the cooperation between the north and south ports, forming a container trunk and branch linkage network with division of labor and cooperation and complementary advantages, with more than 130 container routes and more than 550 flights per month, maintaining trade with more than 800 ports in more than 200 countries and regions in the world.

Lu Xiang, the layout of more than 120 direct stores franchise stores, set up 40 Beijing-Tianjin-Hebei marketing outlets, smooth more than 40 sea-rail combined transport and a number of international land bridge transport channels, set up a new sea channel for the export of foreign trade goods in the west. Tianjin Port China-Mongolia-Russia Economic Corridor Container Multimodal Transport Demonstration Project was awarded the National Demonstration Project.

As a logistics network that radiates inland and covers the world becomes more and more dense, Tianjin Port deeply serves the new development pattern, actively helping the "double cycle", with more confidence and stronger motivation.

Ren Wei, deputy general manager of the business department of Tianjin Port Co., Ltd., introduced that at present, 70% of Tianjin Port's foreign trade containers come from the Beijing-Tianjin-Hebei region, and the three-year average growth rate of the Bohai Rim branch line has reached 37.5; the throughput of ports along the "Belt and Road" accounted for more than 60%; in the first half of this year, sea-rail intermodal transport completed 628000 TEUs, an increase of 25.5 year, the year-on-year growth rate was 79%, ranking first in the country.

At the top of the mountain, you can see the river rushing. Above the peaks, I feel the wind is mighty.

"Facing the future, we will always keep in mind the ardent instructions of General Secretary Xi Jinping, build a world-class green port with greater efforts, build a world-class smart port with updated technology, build a world-class hub port with a broader vision, and continue to enhance the service industry chain and supply Chain capabilities, and strive to build Tianjin Port into a world-class smart port and green port with complete systems, efficient services, and integrated development of port and city, to provide strong support for building an international shipping hub in the north, promoting high-quality development of the regional economy, and promoting the formation of a new pattern of comprehensive opening up." Chu

Bin said.

Under the background of high-quality development, how will the road and bridge industry develop?

In the first year of the 14th Five-Year Plan, China's economy has entered a stage of high-quality development, transforming the mode of economic development, optimizing the economic structure, transforming the driving force of economic growth, and realizing the structural transformation from medium and low-end industries to medium and high-end industries is the theme of economic development for a long time in the future. With the gradual decline of the marginal utility of investment in economic pull, and the proposal of the new development pattern of "double cycle", China's economic growth drive is gradually changing from investment-driven to consumption-driven, therefore, the future investment growth rate of the construction industry will inevitably slow down further. As an important part of the construction industry, the road and bridge engineering construction industry plays a very important role in maintaining the normal operation of social production, circulation, distribution, and consumption, ensuring the sustained, rapid and healthy development of the national economy, improving people's living standards, and promoting the modernization of national defense. However, with the continuous improvement of the highway network and national and provincial highways, the market space of the road and bridge industry is under pressure, and the competition is becoming increasingly fierce. In the future, there are five main trends in the development of the road and bridge industry: First, industrial chain extension and related diversification are effective ways to deal with growth bottlenecks. The upstream and downstream expansion of the industrial chain includes the mining and manufacturing of upstream raw materials, downstream real estate, operation, and EPC construction general contracting. The related diversified development mainly extends to rail transit, water conservancy, environmental protection, maintenance engineering and other fields. Second, the concentration of the industry continues to increase, and market competition is further intensified. The market concentration of the construction industry is low and there are many players. However, with the further deepening of the marketization of the industry and the deterioration of the international environment, large and medium-sized enterprises such as central enterprises and provincial state-owned enterprises have begun to enter the city to seize the regional market and hinder the industry from breaking through. The influencing factors of geographical restrictions have been continuously weakened, the cross-regional competition of the industry has become increasingly significant, and the market concentration is expected to continue to increase. Third, the growth of the eastern market space is limited, and the western market has more room for development. With the low density of road network in the western region and the promotion of relevant policy factors such as the large-scale development of the western region and "Belt and Road Initiative", the investment in infrastructure construction in the western region is gradually strengthening and has become a key area for domestic highway construction. Fourth, intelligent transportation has become a new bright spot in the field of highway construction. Driven by technologies such as ultra-high-speed wireless local area network and 5G mobile communication, smart transportation will be greatly developed in the future. Fifth, the qualification reform promotes the road and bridge enterprises to enhance the degree of marketization and comprehensive strength. In March 2020, the Measures for the Administration of Engineering Cost Consulting Enterprises and the Measures for the Administration of Registered Cost Engineers proposed to lower the qualification threshold for cost enterprises. In July 2020, the Ministry of Housing and Construction issued the Framework of Qualification Standards for Construction Engineering Enterprises (Draft for Comments), proposing to significantly reduce the qualification categories and grades of enterprises. Lowering the entry threshold for the construction industry will further promote road and bridge enterprises to change the traditional concept of "waiting and relying on, really improve the construction ability, technical strength and management ability.


Analysis and Solution Summary of Common Faults of Smearing Machine

1. Smoke from the smoothing machine when working Check the trowel machine to check whether there is too much oil. If there is too much oil, release part of it. It can also be that the piston is broken and severely worn and will burn the oil. If it is damaged, it needs to be replaced in time. Check the engine. If the engine is not faulty, it may also be that there are too many impurities in the oil. The oil is very important. Try to choose high-quality oil. When buying, you must pay attention to prevent buying inferior fake oil. 2. How to level the chassis screws of the smoothing machine First replace 4 new blades and put the trowel in a particularly flat place. Then remove the shift fork and visually inspect whether the heights of the four screws are consistent. If conditions permit, measure them with a ruler. If the heights are inconsistent, adjust them to be consistent. When the gland is gently shaken, if there is no shaking, the debugging is proved successful. Put some butter on the top of the screw to prevent wear. 3. The wiping machine always stalls Observe whether the oil level is normal and whether the oil is too little. Some machines have their own oil protection system, which will automatically turn off when there is a shortage of oil. There is also the fact that after the remote flameout switch and the flameout switch of the machine are disconnected one by one, if the flameout phenomenon does not occur again, it means that there is grounding in that part. Just check and eliminate it carefully. 4. The engine of the trowel is normal, but the trowel is not moved. If there is no problem with the engine, it is caused by the wrong belt type or the belt is too long. If there is still an abnormality, it can be handled by changing a clutch. 5. The gasoline polish machine was blistered First clean the carburetor, let the spark plug be removed to see if there is water in the cylinder head. If there is water, pull the disk several times to drain the water. Try again after changing the oil to see if it is normal. 6. The smoothing machine cannot rotate Reason: The blade may be deformed; the motor bearing is broken; the motor bracket is not fixed well; there is a problem in use.


Method of polishing and grinding

Method of polishing grinding: Grinding is the grinding tool (hereinafter referred to as the grinding tool) surface embedded abrasive or coated abrasive and add lubricant, under certain pressure, the tool and the grinding tool contact and do relative movement, through the abrasive action, from the workpiece surface cut a layer of very thin chip, so that the workpiece has a precise size, accurate geometry and high surface roughness. Its essence is to use free abrasive particles to carry out micro-cutting including physical and chemical comprehensive effects on the surface of the workpiece through the grinding tool. Features:(1) In mechanical grinding, the machine tool-tool-workpiece system is in an elastic floating state. (2) The workpiece to be ground is not subject to any force and is therefore in a free state. (3) The speed of the grinding movement is usually below 30 m/min, which is about 1% of the grinding speed. (4) When grinding, only a very thin layer of material can be cut off, so the heat generated is less, the processing deformation is small, and the surface deterioration layer is also thin. (5) There is residual compressive stress on the grinding surface, which is beneficial to improve the fatigue strength of the workpiece surface. (6) The operation is simple and generally does not require complicated and expensive equipment. (7) Adaptability is good. (8) grinding can obtain very low surface roughness. 1. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium mainly uses special compounds with good flowability at lower pressure. (polymer-like substance) and mixed with abrasive, abrasive can be used silicon carbide powder. 2. Mechanical polishing Mechanical polishing is a method of polishing a smooth surface by cutting and plastic deformation of the surface of the material to remove the convex part after polishing, Generally use oilstone, wool wheel, sandpaper, etc., mainly manual operation, special parts such as the surface of the rotary body, Auxiliary tools such as turntables can be used, and the method of super-lapping can be used for high surface quality requirements. Super lapping is a special abrasive tool, In the polishing liquid containing abrasives, it is tightly pressed on the surface of the workpiece to be processed for high-speed rotating motion. Using this technology, the surface roughness of Ra0.008 μm can be achieved, which is the highest among various polishing methods. Optical lens molds often use this method. 3. Ultrasonic polishing The workpiece is placed in the abrasive suspension and placed together in the ultrasonic field, relying on the oscillation of the ultrasonic, The abrasive is ground and polished on the surface of the workpiece. Ultrasonic machining macro force is small, will not cause deformation of the workpiece, but tooling production and installation is difficult. Ultrasonic machining can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution, The dissolution products on the surface of the workpiece are separated, and the corrosion or electrolyte near the surface is uniform; Ultrasonic cavitation in the liquid can also inhibit the corrosion process, conducive to surface brightening. 4. Electrolytic polishing The basic principle of electrolytic polishing is the same as chemical polishing, that is, by selectively dissolving the small protruding parts of the surface of the material, Make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: (1) Macroscopic leveling dissolution products diffuse into the electrolyte, and the geometric roughness of the material surface decreases, Ra> 1μm. (2) micro light level anode polarization, surface brightness, Ra <1μm. 5. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium is mainly made of special compounds (polymer-like substances) with good flowability at lower pressure and mixed with abrasives, The abrasive may use silicon carbide powder. 6. Chemical polishing Chemical polishing is to make the surface of the material in the chemical medium micro convex part of the concave part of the preferential dissolution, A smooth surface is thus obtained. The main advantage of this method is that it does not require complex equipment and can polish workpieces with complex shapes, Many workpieces can be polished at the same time with high efficiency. The core problem of chemical polishing is the preparation of polishing solution. Surface roughness obtained by chemical polishing Generally, it is several 10 μm. 7. Magnetic grinding and polishing Magnetic grinding and polishing is the use of magnetic abrasive under the action of a magnetic field to form an abrasive brush to grind the workpiece. This method has high processing efficiency, Good quality, easy control of processing conditions, good working conditions. With suitable abrasives, the surface roughness can reach Ra0.1 μm. The polishing in plastic mold processing is very different from the surface polishing required in other industries, Strictly speaking, the polishing of the mold should be called mirror processing. It not only has the very high request to the polishing itself but also to the surface flatness, There are also high standards for smoothness and geometric accuracy. Surface polishing is generally only required to obtain a bright surface. The standard of mirror processing is divided into four levels: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063 μm, due to electrolytic polishing, fluid polishing and other methods are difficult to accurately control the geometric accuracy of the part, The surface quality of chemical polishing, ultrasonic polishing, magnetic grinding polishing and other methods can not meet the requirements, so the mirror processing of precision molds Or mainly mechanical polishing.


What does the floor grinder floor grinder inverter display oL2 mean? Why can't the machine start? How to solve?

The situation is as follows: 1. The ground is very uneven, the resistance of the grinding disc is large, and the motor load is too heavy. 2. If this situation occurs when the new machine is used for the first time, it means that the governor has been adjusted to the fastest speed position, or the new grinding plate (block) Not open rough pressure on the rough hard surface, resulting in a large disc resistance, motor load is too heavy. 3. If the gearbox is repaired and the machine is initially tested like this, it may be that the gear assembly is not smooth and too tight, causing the grinding disc to rotate manually. It is not smooth, or the motor shaft and the center gear are not concentric after the motor is fixed during assembly, that is, the rotation is not concentric, which makes the electricity The rotation of the rotor is blocked and Caton occurs. Corresponding solution: 1, the machine up, move to a relatively flat ground area grinding, and then slowly cut into the uneven ground area, or use Other small grinding disc machinery will ground the rough surface of the potholes slightly smooth, and then use the machine to grind. 2. Roughen the grinding piece (block) on the cement floor. Press down on the armrest and raise the starter of the machine (make the grinding disc slightly off the ground). The machine (grinding disc) can be slowly landed. 3. Reassemble the gear or reassemble the motor to make the gear and the grinding disc rotate smoothly. After inserting the motor shaft into the central gear Concentric, suspend the motor and the box and energize the motor to start the motor, so that the motor, gear and grinding disc rotate smoothly. After shutdown, hand Rotate the grinding disc smoothly.
