Research on electro-hydraulic control technology of train with long distance self-moving equipment

Abstract

Aiming at the problems of manual laying of tracks, sliding car and dropping lanes in the process of traditional train transportation of winch traction equipment, this paper presents a long-distance self-moving equipment train, which is powered by hydraulic pressure, self-contained track, highly integrated train self-moving, walking deviation, anti-dropping and other functions, so as to realize the striding forward movement of the whole equipment train driven by the traction device. Innovative adopt of loop liquid supply, multiple group remote control and other technologies, and using multi-master control, and high reliability, strong anti-interference CAN (Controller Area Network) fieldbus real-time control network, it ensures the synchronous and smooth lifting of the train, and it moves forward with the self-moving traction device. Thereby, the automatic system development and demonstration application of the fully mechanized mining equipment can be realized.
