An automatic control system and method for a front side guard of a hydraulic support

Abstract

The invention discloses an automatic control system and method for front face guards of hydraulic supports and belongs to the field of hydraulic support control. The system comprises a coal mining machine onboard module and a hydraulic support control module. The coal mining machine onboard module is mainly used for acquiring all parameters of a coal mining machine in real time, controlling the coal mining machine to work through a logic decision and communicating with the hydraulic supports; and the hydraulic support control module is mainly used for sending out signals of the hydraulic supports, acquiring the parameters of the hydraulic supports in real time, controlling the hydraulic supports and communicating with the coal mining machine. By the adoption of the automatic control system and method, cooperative control over the front face guards of the hydraulic supports and the coal mining machine can be achieved, the front face guards of the hydraulic supports can be controlled automatically without manual operation, the labor intensity of workers and coal mining accidents are reduced, and the flexible manpower line requirement and the unmanned requirement of fully-mechanized coal mining are met.

Description

technical field [0001] The invention relates to an automatic control system and method of a hydraulic support, in particular to an automatic control system and method of a front side guard of a hydraulic support, belonging to the field of hydraulic support control. Background technique [0002] Coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce the physical labor of workers, improve safety, and achieve the purpose of high output, high efficiency and low consumption. Hydraulic support is a kind of hydraulic power device that uses liquid pressure to generate support force and realize automatic displacement for roof support and management. It is an indispensable supporting equipment for comprehensive mechanized coal mining. [0003] At present, when using a shearer to cut top coal, the extension and retraction of the front side guard of the hydraulic support are manually...

AI Technical Summary

Problems solved by technology

This method mainly has the following disadvantages: (1) the completion of this kind of work mainly depends on the worker's operation, and the worker needs to follow the shearer all the time on the fully mechanized mining face. On the one hand, the labor intensity of the worker is high, and it is not conducive to ensuring the safety Personal safety, on the other hand, cannot meet the fully mechanized mining requirements of less people and no one; (2) Failure to operate in time may easily lead to accidents: if workers cannot operate and retract the front side guard of the hydraulic support in time, the shearer will cut The front side guard will cause coal mine accidents; if the worker cannot extend the retracted front side guard in time, the supporting function of the hydraulic support will not be well realized, which is not conducive to the safe production of the coal mine
