Construction machinery gradually began to pick up in 2017, but the uncertainties that affect the economic operation of the industry still exist. Experts predict that the machinery industry will still undergo a severe test. With the gradual attainment of the national macro-control policy, the macroeconomic situation will gradually improve, the downward trend in the machinery industry will gradually stabilize, and the positive factors in the development of the industry will also accumulate. Some enterprises, industries, and regions that started restructuring earlier will gradually Accelerate the recovery. Technology leads the future, innovation drives development. So, what are the mainstream technology trends in the construction machinery industry?
First, the modular design and virtualization manufacturing
Modular design includes the previously mentioned part of the generalization and design of software modules. Modular design software allows different systems or components to be assembled on the computer and change parameters, which greatly accelerated the design of new product development progress. Information technology and the global economy have created the conditions for the virtual manufacturing of machinery manufacturing. Among the major multinational construction machinery companies, a clear trend is for manufacturers to focus their efforts on research and development and assembly of equipment, not manufacturing parts, and pushing it to parts suppliers. Host product manufacturers and component suppliers and research and development institutions to work together to play a creative spirit of all parties to jointly develop and produce marketable products.
Second, the coexistence of personalized and multi-functional
The different types of engineering, materials, scale and different construction environment put forward the requirements of individualization and multi-function for construction machinery. The development of modern design technology and flexible manufacturing technology also created the conditions for the realization of product individuation and multi-function. Personalized products are adapted to a particular situation and appear, and a multi-purpose construction machinery is the development of another direction, which will undoubtedly increase the utilization of equipment.
Third, increasing environmental protection requirements
For the sake of the sustainable development of human society and economy, the world public has put more and more strict requirements on environmental protection. Whether the construction machinery has good environmental performance will become one of the important indexes for participating in the international market competition. Nowadays, many industrial developed countries, “Market Access Card.” Therefore, all countries in the United States, Europe, Japan actually developed engineering machinery that is “friendly to both people and the environment.”
Fourth, to speed up the upgrading
With the development of modern technology, the technology development and innovation of the world’s construction machinery products have been accelerated and the cycles of replacement have been shortened. The product families have been broadened and the product series become more sophisticated. The major US, European and Japanese companies have introduced the cameras The second generation, the third generation until the fifth generation of new construction machinery products.
Fifth, small and large size with the development
Large and medium-sized construction machinery is still the mainstream of construction machinery in the world, with annual sales of about 70 billion U.S. dollars. However, the tendency of construction machinery to extend toward both ends of miniaturization and large-scale construction is obvious. The United States, Europe, and Japan are the major consumer markets for construction machinery. As their large-scale infrastructure construction projects have been declining while those for repairing, protecting and urban small-scale projects are on the increase, in order to save labor and labor costs and increase work efficiency, various small, Micro-engineering machinery have come out. This machinery and equipment can be used for construction work in narrow areas or in residential homes and small-scale construction projects.
Sixth, the concept of industrial design throughout the product design
Industrial design is the product of the design, also known as the product’s artistic style. Construction machinery design can make the shape of the machine and its structure, function and use requirements of unity, and with people’s physical and mental coordination. This design should include the appropriate proportion of the ministries, body shape, color coordination, beautiful appearance of the instrument layout, as well as easy to operate intuitive and eye-catching trademark symbols. At present, the world’s major companies attach great importance to the industrial design of products that led to the emergence of a special research and design agency.
Seventh, robots to help create construction machinery
Ergonomic principles have been valued Since the 1980s, many of the world’s largest construction machinery manufacturing companies have invested a lot of manpower and funds to research and application of modern design methodologies Ergonomics Advocate people-oriented design ideas, pay attention to the machine Coordination with people. The application of electronic technology in construction machinery greatly simplifies the driver’s operating procedures and improves the technical performance of the machine. The use of electronic control can automatically select the machine mode of operation; the use of electronic monitoring can promptly detect and eliminate the failure of the machine system; the use of electronic sensors by microcomputer processing can automatically detect the quality of the machine.
Robots play a “catalyst” role in the transition of emerging and traditional industries. In the construction machinery industry, robots often perform spot welding, arc welding, painting and assembly on the production line. This not only ensures the stability of product quality and improves the efficiency of labor productivity, but also improves the working conditions and labor intensity of workers. In recent years, China’s construction machinery industry usher in rapid development, the urgent need to upgrade and restructuring, enterprises want to grab more competition in the market share and get rid of homogenization of the product competition, we must strengthen the level of automation of the production line, vigorously introduce the robot will not Or missing.
In addition, the performance and price of construction machinery products depend greatly on these spare parts, such as transmission parts, control components, diesel engines and key hydraulic components such as high-tech, high value-added core components, and in our country these projects Mechanical core parts mainly rely on imports, a serious constraint on the situation of China’s construction machinery enterprises to further develop and grow. Because foreign companies that control the core spare parts usually take the form of starvation sales, only a certain number of accessory products are produced each year, so as to achieve the purpose of guaranteeing price control. As an emerging industry that is nurturing and growing, there are still outstanding problems in the intelligent manufacturing equipment industry in our country. The main problems are as follows: weak technological innovation ability, limited core technologies such as new sensing and advanced control, small industrial scale, small industrial organization, , Weak and lack of internationally competitive backbone enterprises; industrial base is weak, high-grade and specialty sensors, intelligent instrumentation, automatic control systems, high-end CNC system, the robot market share of less than 5%.
Eighth, operating principle breakthrough
Operating principles of innovation and breakthroughs, working principle of construction machinery, including earthwork cutting, crushing, backfilling, geotextile screening, mixing and heating, paving the mixture, leveling, and compaction. The theory of these operations was originally based on bionics and Newtonian mechanics, while the development of shock science laid the foundation for the new operating principle of construction machinery. For example, the application of mechanical vibration, pulse, jet, photoelectric effect, and thermophysics has created the conditions for the construction machinery to save resources, improve the project quality, improve the production efficiency, work reliability, driving comfort and automation.
Ninth, hydraulic transmission
In the 1960s began to be applied to the roller, only 10 years time has been promoted and popularized. The existing road roller walking, vibration, steering machine brake and other systems have achieved full hydraulic transmission. Hydraulic transmission greatly simplifies the design of the roller drive and control system, hydraulic transmission smooth and easy operation, easy to implement stepless speed control and automatic control, to improve the overall roller production efficiency and compaction quality.
Tenth, one of the telecommunications and intelligent process
Modern engineering machinery should give humanity and spirituality. Spiritual construction machinery is an integrated system of mechano-telecom transmission with thought and mind sensing organs, neural networks, internal organs and hand, foot and skeleton. Electronic technology and sensors and mechanical devices combined to achieve automatic monitoring of construction machinery and automatic control, that is, the integration of telecommunications. The electronic sensor is one of the sensors of the machine and the organ of the machine. It is the medium between the machine and its work object. The electronic technology which is the core of the computer is the brain and central nervous system integrated with the machine and telecommunications. It accepts all kinds of information sent by the sensor, After processing the execution part of the machine instructions.
