Keywords: mechatronics; construction machinery
Construction machinery operators need to master the most advanced electromechanical integration technology and apply it to practical work in order to give full play to the advantages of electromechanical integration technology. Of course, this also requires construction machinery enterprises to provide such opportunities for operators. Modern construction machinery industry has entered the era of mechatronics, and the application of this technology makes the operation of construction machinery more convenient and the product performance more excellent. At present, most enterprises in China have applied mechatronics technology. With the improvement of this technology function, mechatronics technology will be applied in more fields.
1 Advantages of mechatronics technology
First of all, the safety performance is high. After the application of mechatronics technology in construction machinery, the products it produces usually have high performance and full functions, including monitoring, alarm and automatic protection. If there is any abnormality in the operation of the equipment, the mechatronics product may automatically protect it to ensure that the operator and the equipment will not be seriously damaged, thus ensuring the safety of the equipment. Secondly, the production capacity is strong. Electromechanical integration equipment in construction machinery can automatically process information and control at the same time, with high control accuracy and high detection sensitivity. Electromechanical integration equipment has a control system. In the process of equipment operation, as long as the operator starts the system, the equipment can complete all the specified actions according to the design requirements, which can not only ensure the efficiency of product production, but also ensure the performance of the product to meet the requirements. In addition, the application of automation technology makes the application value of electromechanical integration technology greater. Third, the use performance is strong. The mechatronics equipment can display numbers and has the function of program control, so there is no need to design too many handles and buttons, which is very convenient to operate. In addition, mechatronics technology can repeat actions, and if the equipment is very advanced, it can also automatically select programs, greatly reducing the workload of operators. Finally, it has a wide range of applications. Electromechanical integration equipment combines composite technology and has certain composite functions. Compared with other technologies, it can be applied to more fields. Traditional technology is usually single in technology, single in function and limited in application. However, the electromechanical integration technology is completely opposite. Composite technology and composite function make the overall function of the equipment more powerful and can fully meet the needs of users.
Application of mechatronics in construction machinery
In construction machinery, the application of advanced technologies such as electromechanical integration technology makes the performance of construction machinery more powerful, and at the same time, it can ensure the production process more economical and safe.
2. 1 Operation accuracy control of construction machinery
In construction machinery, the accuracy of finished products is very important. If there are obvious errors in the accuracy of the main parameters, the performance of the product will be greatly affected. The application of mechatronics technology can ensure the control of various main parameter data in construction machinery production. For example, when mixing concrete, if the weight of each raw material depends on the traditional measuring tools, errors will inevitably occur, and the electronic weighing system controlled by microcomputer can accurately weigh all kinds of raw materials, with low errors, and the performance of concrete will not be guaranteed. In addition, in the construction of pavement engineering, the application of automatic leveling system can make the pavement more flat. In addition, due to the integration of ultrasonic technology in the automatic feeding system, automatic feeding can be carried out, so that the paving quality is fully guaranteed.
2.2 Application of construction machinery automation and semi-automatic operation
The realization of automatic and semi-automatic operation greatly reduces the work intensity of operators and improves the production efficiency of the project. The introduction of automation technology can also avoid the mistakes of some inexperienced personnel and ensure the accuracy of operation. For example, Mitsubishi Corporation of Japan introduced the excavation trajectory control system into the excavator, set the movement trajectory of the consumption bucket, and automatically controlled the movements of the boom and bucket through the microcomputer control system, making the excavation operation more accurate.
2.3 Application of monitoring function in construction machinery
With the introduction of mechatronics technology, the process of construction machinery can be monitored in real time, including transmission system, actuator, braking system and hydraulic system. When an abnormal situation occurs, it will automatically give an alarm and accurately find out the fault location.
2.4 Application of Energy Saving in Construction Machinery
For traditional construction machinery, the energy utilization efficiency is low, and the effective utilization rate of hydraulic excavators in fuel energy utilization is only 20%, which makes construction machinery urgently require energy saving. The excavator of Komatsu Company in Japan has adopted a new energy-saving controller, that is, OLLS system, which can save 25% fuel in energy-saving effect.
2.5 Other applications
In foreign countries, automatic transmissions are added in the production process of bulldozers, scrapers and loaders, which can adjust the transmission ratio of the transmission system according to the external load, so that the power of the engine can be fully utilized, the energy economy is also improved, the operation is more convenient, and the work intensity of operators is reduced.
3 Development trend of electromechanical integration technology of construction machinery
The development trend of electromechanical integration technology of modern construction machinery is mainly towards high performance, miniaturization and intelligence. In terms of high performance, the main goal is the four highs of application mode, that is, high precision, high efficiency, high reliability and high speed of application mode. For example, in the new generation of CNC system, multi-CPU structure and multi-bus connection are mainly adopted to meet the four high requirements in application mode. The application of this system can handle multi-task operating system at the same time, and realize the production of high-performance products. Miniaturization is the new development goal and direction of mechatronics technology, and it is also the basis of realizing the nano-scale combination of electronic technology and mechanical technology. Micro-electromechanical integration products mainly refer to nano-scale and micron-scale products, and the volume is generally below 1 cubic centimeter. This micro-electromechanical integration technology product has the characteristics of compactness, energy consumption and flexible movement. In the development of mechatronics technology, intelligence is also a trend. For the modern mechatronics technology, its development is inseparable from the control theory, which is also the embodiment of the difference and intelligence between the mechatronics technology and the traditional mechatronics technology. Intelligence is mainly reflected in the use and function of products in the actual production process. Intelligentization mainly combines the ideas and methods of artificial intelligence, physiology and computer science to imitate human intelligence, thus making the application scope and performance function of mechatronics technology more modern.
Concluding remarks
To sum up, we can see that modern life has very high requirements for the production and manufacture of construction machinery. Traditional technology not only has low manufacturing efficiency, but also can't guarantee product performance. Therefore, it is necessary to apply advanced technology to improve production efficiency and product performance. Electromechanical integration technology is the most advanced technology applied in construction machinery, which can meet the basic requirements of construction machinery manufacturing at present. Future technology will develop in the direction of higher performance, miniaturization and higher intelligence. Although it will take some time to achieve this goal, with the progress of science and technology, the time to achieve this goal will be closer and closer.
