"Customs declaration is made online at 9: 00 a.m. and the goods can take the latest rail-sea intermodal train from Chongqing to Qinzhou Port in Guangxi at 11: 00 a.m. for shipment to Southeast Asia, South Asia and other regions." Liu Yizhen, assistant to the general manager of Luhai New Channel Operation Co., Ltd., introduced that since this year, the company has exported various types of goods such as mechanical products to 29000 TEUs, a year-on-year increase of 20%.

During an inspection tour in Yunnan in January 2020, General Secretary Xi Jinping pointed out that it is necessary to take the initiative to serve and integrate into the country's major development strategies, promote great development with great opening up, and speed up the construction of international channels for connectivity with neighboring countries. During his inspection tour of Guangxi in April 2021, General Secretary Xi Jinping stressed that we should integrate into the "Belt and Road Initiative", jointly build a new land and sea channel in the western region at a high level, vigorously develop the economy to the sea, promote China-ASEAN opening up and cooperation, and run a pilot free trade zone. better transform the unique geographical advantages into the advantages of open development.

Keeping in mind the entrustment of General Secretary Xi Jinping, in recent years, Guangxi and Yunnan have relied on the implementation of national strategies such as the new land and sea corridors in the west, focusing on the joint construction of the "Belt and Road", and continuously strengthening cooperation with neighboring countries in infrastructure construction, optimizing customs clearance services, and promoting industrial cooperation and upgrading. Transform location advantages into development advantages and achieve a higher level of opening up.

Vegetables and flowers, fertilizer feed, daily necessities ...... Huge boom will be loaded with all kinds of cargo containers hoisted to the train, along the China-Laos railway, from Kunming to Vientiane, the capital of Laos. In December 2021, the China-Laos railway was officially opened to traffic. From Kunming to Vientiane, the mountain is no longer high and the road is no longer long.

"The China-Laos Railway International Freight Train' Lan-Mei Express Line starts from Kunming and arrives in Vientiane in 26 hours at the fastest." Vice President of China Railway Lianji Kunming Central Station

General Manager Xu Chao said that as of June 30 this year, the China-Laos Railway had completed a total of 4 million passengers and 4.94 million tons of goods.

The China-Laos railway trains are speeding, and the Beibu Gulf ships are sailing. On June 13, berth 501, the first LNG loading and unloading terminal in Fangcheng Port District of Beibu Gulf Port, welcomed the first Panamanian cargo ship carrying 3434 tons of LNG liquefied gas to berth smoothly.

"Beibu Gulf Port has increased investment in port infrastructure, a number of high-grade waterways and large-scale wharf berths have been built one after another, and the waterway capacity has continued to improve." Guangxi Beibu Gulf Port Group Chairman Li Yanqiang said. As of the end of 2021, the Beibu Gulf Port container railway train has reached 13 provinces, and the container liner route covers more than 200 ports in more than 100 countries and regions around the world.

At the same time of infrastructure upgrading, port customs clearance services are also being optimized. At Mohan Railway Port in Yunnan, the newly put into use H986 railway large container inspection equipment can automatically scan the whole train when the train is traveling normally, and it only takes 2 minutes to scan a single train.

"Starting in June this year, the Sino-Vietnamese train 'railway fast' mode to achieve cross-regional two-way connection. The train can submit applications at the customs at the origin, declaration, inspection and other procedures are all completed at one stop, after arriving at the port without any customs clearance procedures, compared to the past to save customs clearance time of about 24 hours, a single box can also save more than 200 yuan in costs." Sinotrans Guangxi Co., Ltd. Liang Peng said.

Kunming Customs introduced 13 customs clearance facilitation measures, the use of transit exports and national customs clearance integration model, to achieve rapid customs clearance under the supervision of the whole chain of customs; Nanning Customs landed to implement "two-step declaration", "ship side direct lifting, arrival direct loading" and other reform initiatives ...... The optimization of customs clearance services to make the road more open.

On January 1, 2022, the "Regional Comprehensive Economic Partnership Agreement" (RCEP) officially entered into force, and Guangxi and Yunnan ushered in new opportunities for open development.

"This batch of goods weighs 7.3 tons, including household goods, hair accessories, etc., and will soon be delivered to customers in RCEP member countries." Li Yan, head of operations of Baishi Supply Chain (Pingxiang) Co., Ltd., a cross-border e-commerce public customs clearance center in Pingxiang City, Guangxi, is declaring cross-border e-commerce goods. "In the first quarter of this year, the value of the company's cross-border e-commerce exports exceeded 0.21 billion yuan, up 12.6 percent from the same period last year."

Grasp the RCEP dividend and promote the upgrading of international industrial cooperation. The two provinces press the fast forward button: Guangxi accelerates the construction of a new cross-border e-commerce trade system. On June 9, the China-ASEAN (Pingxiang) cross-border industrial service cloud platform project was launched, which is expected to incubate hundreds of live broadcast enterprises and financial enterprises. In January 2022, Yunnan will issue relevant action plans, proposing 21 measures in 5 aspects around RCEP contents, facing ASEAN, consolidate the export of fruits, vegetables, flowers and other agricultural products, expand the export of matsutake, coffee, tea and other products to Japan, South Korea and other countries, promote the import of high-tech products, and strive to do a good job in the big article of "internal and external coordination, two-way opening up......

To build a new highland of open development, Guangxi, Yunnan hoof steady, the future can be expected.

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.
