With the development of automobile technology, the production and use of domestic dump trucks have increased, especially in recent years, the development of medium and heavy cargo top-mounted dump trucks has been rapid. With the continuous improvement of the center of gravity of medium and heavy dump trucks, the stability of the hydraulic lifting system is directly related to the safety of the dump truck, and the loading efficiency and maintenance cost of the dump truck will have an impact. The oil cylinder of its dump truck uses multi-stage oil cylinder, Therefore, the cylinder stroke is longer.
The general test bench cannot complete the overall performance test of these oil cylinders. At present, the domestic oil cylinder test technology is relatively superior. In the analysis of the common faults of the dump truck oil cylinder, according to the relevant standards of the dump truck oil cylinder test, the test elements and test methods of the oil cylinder are analyzed. On this basis, the software and hardware of the detection system are designed, and the detection system that can automatically complete the oil cylinder is developed, The inspection system is mainly used for the delivery test of the lifting cylinder of the dump truck.
The inspection system is composed of hydraulic load system and electrical control system. When the loading gantry is erected, considering the longest stroke of the cylinder, the loading scheme of the cylinder is improved according to relevant regulations. The loading platform is designed as a parallel horizontal structure, which can simulate the actual working conditions of the cylinder. The hydraulic components are designed with proportional electrohydraulic technology to implement the pressure and flow. The electrical control part is controlled by industrial computer.
Using the development tools and virtual instrument technology to develop the control software, we also learned the load principle and load control scheme of the electro-hydraulic proportional valve, and selected test equipment such as sensors to purify the inspection system, and input the test program of the relevant test items during the trial operation of the oil cylinder, so that the detection system achieved the expected goal, and at the same time, we can complete the detection of different oil cylinder sizes, The detection system can complete the test automatically, with accurate detection characteristics and high detection efficiency.
