Description

TECHNICAL FIELD

[0001] The present application relates to the field of tunnel construction technology, in particular to an electro-hydraulic distributed system for an arch frame trolley. BACKGROUND

[0002] With the continuous development of computer technology and electronic technology, the intelligent trend of engineering machinery is constantly advancing, and the application of various electronic monitoring systems, wireless operation, online fault detection and diagnosis functions, the requirements for electro-hydraulic control systems are getting higher and higher. The traditional electro-hydraulic control system of the arch frame trolley has the following problems:

[0003] (1) The arch frame trolley tunnel arch operation needs multi-action cooperation, and the control system and intelligentization requirement is getting higher and higher. At present, the electro-hydraulic control system adopts a form of an electric control cabinet to control the valve group of the whole machine. All valve group control lines need to be drawn out from the electric control cabinet and connected back to the electric control cabinet. The whole machine electrical circuit is very complex and the cost is high, and it is not conducive to fault troubleshooting operation.

[0004] (2) With the increase of the electro-hydraulic control function of the arch frame trolley, the performance requirements of the electric control cabinet and the controller are getting higher and higher. It is difficult to meet the requirements of today by using a single electric control cabinet and controller. At the same time, it is impossible to troubleshoot faults by partitioning, which not only increases the cost of the product, but also reduces the reliability of the product.

[0005] (3) The valve group of the arch frame trolley is too concentrated. When the valve group and the actuator are too far apart, more steel pipes or hoses are needed to connect them, which is not conducive to the arrangement of the whole machine hydraulic pipeline, and will increase the cost of the whole machine.
