Abstract

The invention relates to an electro-hydraulic control system for a working surface hydraulic support. The electro-hydraulic control system comprises a support controller (14), and a control terminal, an information acquisition device and an electromagnetic driver (21) which are connected with the support controller (14), wherein the control terminal is used for inputting an order and displaying received data information, the information acquisition device is used for acquiring the operating parameter data of the hydraulic support, and the electromagnetic driver (21) is used for driving an electro-hydraulic control valve group (22). The electro-hydraulic control valve group (22) connected with the electromagnetic driver (21) is used for controlling the closing and opening of a tube liquid pathway of the hydraulic support. The support controller (14) is used for transmitting the order from the control terminal and supplying the operating parameter data of the hydraulic support acquired by the information acquisition device to the control terminal. The electro-hydraulic control system is applied to the working surface hydraulic support.

Description

technical field [0001] The invention relates to the technical field of control of a fully mechanized mining face in a coal mine, in particular to an electro-hydraulic control system for a hydraulic support of a working face. Background technique [0002] With the continuous development of coal mining technology, the control system of the hydraulic support has been greatly improved. The control system has been gradually improved from the original manual operation to the electro-hydraulic automatic control, which greatly speeds up the moving speed of the working face. [0003] As early as the 1950s, the United Kingdom had included the remote control technology of the hydraulic support in the research plan. From the late 1980s to the early 1990s, with the development of microelectronics technology, the British Road Ladder Company first developed a full working surface. Electro-hydraulic control system, followed by Westphalian and Marco company to develop Pm2 electro-hydraulic c...
