Road milling machine development prospects forecast roughly includes the following steps: 1. Identify objectives Clear purpose is the first step to carry out the prediction of the development prospect of road milling machine, because the purpose of the prediction is different, the content and project of the prediction, the required information and the method used will be different. Clear forecast target, is based on the road milling machine business activities of the existing problems, the development of forecast projects, the development of forecast work plan, budget preparation, deployment of forces, organization and implementation, in order to ensure that the road milling machine development prospects forecast work in a planned and rhythmic manner. 2. Collect information It is necessary to have sufficient information to predict the development prospects of road milling machines. With sufficient information, it can provide a reliable basis for analysis and judgment for the prediction of the development prospect of road milling machine. Under the guidance of the road milling machine development prospect prediction plan, investigating and collecting the relevant data is an important part of the road milling machine development prospect prediction, and it is also the basic work of the prediction. 3. Selection method According to the target of the forecast and the applicable conditions of various forecasting methods, the appropriate forecasting method is selected. Sometimes multiple forecasting methods can be used to predict the same target. The accuracy and reliability of the prediction will be directly affected by the selection of the prediction method. The core of the prediction method of the development prospect of road milling machine is to establish a model that describes and summarizes the characteristics and change laws of the research object, and to calculate or process according to the model, the prediction results can be obtained. 4. Analysis and correction Analysis and judgment is a comprehensive analysis of the data collected by the survey, and through judgment and reasoning, the perceptual knowledge is raised to rational knowledge, from the phenomenon of things to the essence of things, so as to predict the future development and change trend of the road milling machine market. On the basis of analysis and judgment, the original forecast results are usually evaluated and revised according to the latest information. 5. Preparation of the report The road milling machine prediction report should summarize the main activity process of the prediction study, including the prediction target, the prediction object and the analysis conclusion of the relevant factors, the main information and data, the selection of the prediction method and the establishment of the model, as well as the evaluation, analysis and correction of the prediction conclusion, etc. Related research results: Research Analysis and Development Trend Forecast Report of China Road Milling Machine Industry from 2022 to 2028 Global and China Road Milling Machine Market Research and Prospect Trend Analysis Report 2022-2028 China Road Milling Machine Market Survey and Prospect Analysis Report 2022-2028 To do a good job in predicting the development prospects of road milling machines, it is necessary to grasp the four basic elements of prediction: 1-Information. Information is the characterization and reflection of the characteristics and changes of objective things, exists in all kinds of carriers, and is the main work object, work basis and result reflection of road milling machine prediction. 2, the method. Methods refer to the various means used in the qualitative and quantitative analysis of the prediction process. The methods of prediction can be divided into different categories according to different criteria. According to the attributes of road milling machine prediction results, it can be divided into qualitative prediction and quantitative prediction, and according to the length of prediction, it can be divided into long-term prediction, medium-term prediction and short-term prediction. According to the method itself, it can be divided into many categories, the most basic is model prediction and non-model prediction. (3) Analysis. Analysis is a thinking research activity based on relevant theories. After the prediction conclusion is drawn according to the prediction method, two aspects of analysis must be carried out: one is to analyze whether the prediction results conform to the conditions of economic theory and statistical analysis in theory, and the other is to analyze the accuracy of the prediction error in practice and evaluate the reliability of the prediction results. 4-Judgment. Forecasting should follow certain procedures and steps to make the work orderly, integrated planning and collaborative. There are many methods to predict the development prospect of road milling machine, mainly the following: 1 Time series In the prediction of the development prospect of road milling machine, a series of economic index values that change according to time are often encountered, such as the annual (quarterly) sales and supply of road milling machine products, which are arranged in chronological order. A set of data is called time series. The method of predicting by time series is called time series prediction. 2-Return (1) Meaning of "return. Regression is used to analyze and study the dependence between one variable (the dependent variable) and one or more other variables (the independent variable), with the purpose of estimating or predicting the overall mean of the dependent variable based on a set of known independent variable data values. In economic forecasting, people use the object of forecasting (economic indicators) as the dependent variable, and those factors that are closely related to the object of forecasting as the independent variable. Based on the historical and statistical data of the two, a regression model is established and used for prediction after statistical testing. Regression prediction has a one-way regression prediction of an independent variable and a multiple regression prediction of multiple independent variables, and only the one-way linear regression prediction method is discussed here. (2) Basic conditions for regression analysis. When applying a known set of independent variable data to estimate and predict the value of a dependent variable, these two variables need to meet the following two conditions: First, statistical correlations. A statistical correlation is an uncertain functional relationship, I .e. a functional relationship in which the value of a dependent variable (predictor variable) is clearly related to the value of one or more independent variables, but is not precise and cannot be uniquely determined, where the variables are random variables. This correlation exists in a large number of economic phenomena. Second, causality. If one or more independent variables x change, according to a certain law affects another variable y, and the change of y cannot affect x, that is, the change of x is the cause of the change of y, and not the other way around, then the model that reflects the causal relationship between x and y is called the regression model. 3. Qualitative and quantitative Another classification method of classification development prospect prediction can be divided into qualitative prediction and quantitative prediction. For corporate marketing managers, the main business forecasting methods that should be understood and mastered are: (1) Qualitative prediction method The qualitative prediction method, also known as the intuitive judgment method, is a method often used in the prediction of the development prospects of road milling machines. Qualitative forecasting relies primarily on the information, experience and comprehensive judgment of forecasters to predict future market conditions and trends. Such forecasting methods are simple and easy to implement and are particularly suitable for problems where it is difficult to obtain comprehensive information for statistical analysis. Therefore, the qualitative prediction method is widely used in the prediction of the development prospect of road milling machine. Qualitative forecasting methods include: expert meeting method, Delphi method, sales staff opinion collection method, customer demand intention survey method. (2) Quantitative forecasting method Quantitative prediction is the use of relatively complete historical data, the use of mathematical models and measurement methods to predict the future market demand for road milling machines. Quantitative prediction is basically divided into two categories, one is the time series model, the other is the causal relationship model. With the increasing competition in the road milling machine industry, mergers and acquisitions, integration and capital operation among large enterprises are becoming more and more frequent. Excellent road milling machine enterprises at home and abroad pay more and more attention to the analysis and research of the road milling machine market, especially the in-depth study of the current road milling machine market environment and customer demand trends, in order to occupy the market in advance and obtain a first-mover advantage.

Working principle of milling machine

Pavement milling machine is one of the main types of asphalt pavement maintenance and construction machinery. One of the main equipment for asphalt concrete pavement maintenance and construction is mainly used for the excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, freight yards, etc. It can also be used to remove defects such as pavement embossment, oil waves, mesh patterns, rutting, etc. It can also be used to excavate potholes and grooves on the pavement, and milling of cement pavement. Milling the damaged old pavement with a road milling machine, and then laying a new surface layer is one of the most economical modern maintenance methods. Because of its high efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good mobility, milling of old materials can be directly recycled, etc., it is widely used in urban municipal roads and highway maintenance projects. Main structure and working principle The general milling machine is composed of engine, frame, milling rotor, milling depth adjustment device, hydraulic components, aggregate conveying device, steering system and braking system. The milling rotor is the main working part of the milling machine. It is composed of the milling rotor shaft, the cutter seat and the cutter head. It directly contacts with the road and achieves the purpose of milling through its high-speed rotating milling cutter. The milling machine is equipped with an automatic leveling device, which uses the side cover of the milling rotor as the milling reference surface and controls two positioning hydraulic cylinders to keep the given milling depth constant; Its hydraulic system is used to drive the milling rotor to rotate, the whole machine to walk, auxiliary device work, etc. It is generally a closed hydraulic system with multiple pumps independent of each other, which does not interfere with each other and has high reliability when working. Some milling machines are equipped with inclination adjusters as required to control the inclination of the rotor. Generally, large milling machines have an aggregate conveying device composed of a conveyor belt and a collector, which can concentrate and transfer the milled bulk material to a random walking vehicle. The height of the conveying arm can be adjusted and can swing left and right to adjust the unloading position. When the specifications and models of the milling machine are different, their structure and layout are slightly different, but the basic working principle is the same or similar. The route of power transmission of milling machine: engine → hydraulic pump → hydraulic motor, hydraulic cylinder → working device.

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.

Emery wear-resistant floor development process

Emery wear-resistant floor development process Speaking of the origin of emery wear-resistant floor, it is understood that in the initial stage of industry, the ground laying of industrial plants in China is generally very simple water surface. With the arrival of reform and opening up, the imported emery wear-resistant floor has gradually appeared in the market of our country. People begin to understand the role of aggregate. It turns out that as long as a certain amount of aggregate is added to the cement floor, the use strength and brightness of the ground can be improved. After curing treatment of emery wear-resistant ground, the market more static two types of aggregate floor is terrazzo ground and emery ground. Emery ground entered the market later than terrazzo ground. As an upgraded replacement of terrazzo ground, it has better wear resistance. Emery ground began to appear in the European and American markets in the 1970 s. Due to the obvious priority of emery itself, in the late 1980 s, however, emery ground was introduced from abroad to China in the 1990 s. Like its performance in foreign markets, emery ground quickly attracted the attention of the public due to its advantages of wear resistance and compression resistance, dust reduction, hard surface, easy cleaning, economy and durability. It opened the domestic market very quickly and won unanimous praise. Emery wear-resistant flooring process is not just to add aggregate so simple, although the carborundum ground wear resistance is better, but its internal structure is relatively loose, so its moisture-proof, dust-proof, anti-seepage ability will be worse. In order to improve this shortcoming, we will use the concrete seal curing agent to deal with the emery floor, the abrasion resistance and hardness of the treated emery floor will be improved, and the sealing effect of the concrete seal curing agent material can also effectively improve the moisture-proof and anti-seepage ability of the ground, and effectively solve the problem of dust and sand.

The excellent performance of emery wear-resistant floor

Social progress is reflected in all aspects of life, such as the floor. Now the development of the floor can be said to be an indispensable thing in our lives. For many people, it is very difficult to walk on hard ground and then walk on muddy roads. With the development of the times, the change of the floor has also experienced many periods. At present, the emery wear-resistant floor is a popular type of floor. Emery wear-resistant floor has many excellent properties, which is the reason for its wide application. Due to the excellent performance of diamond wear-resistant floor, in life to avoid the floor moisture, moisture and many other issues, its excellent flatness, flatness and smoothness can also avoid local damp floor. And if ordinary concrete, we know that the humidity of concrete is indeed the most common picture, especially in summer, when the humid air with higher temperature (relative humidity greater than 90%) meets the ground with lower temperature, smooth, and non-absorbent, The condensation of water droplets does bring great inconvenience to life. Due to its compact structure, it is not easy to be penetrated by water and gas, and naturally avoids moisture. Due to its high hardness, the service life of the emery wear-resistant floor is very long, and the problem of using twenty or thirty years is really not big.
