液压支架自主跟机控制系统的设计与试验

Design and Test of Control System of Hydraulic Support Autonomous Follower

针对传统液压支架控制效率低、作业人员劳动强度大的问题,在介绍液压支架机械结构、液压驱动部分以及电液控制部分的基础上,基于电液控制器设计了自主跟机控制系统。经工业性试验表明,该自主跟机控制系统能够实时精确掌握采煤机的位置,并按照预期实现对液压支架自主跟机操作,为提升综采工作面的生产效率奠定基础。

In view of the low control efficiency of the traditional hydraulic support and the large labor intensity of the workers, the autonomous following machine control system is designed based on the electro-hydraulic controller on the basis of the introduction of the mechanical structure of the hydraulic support, the hydraulic driving part and the electro-hydraulic control part. The industrial test shows that the control system can grasp the position of the shearer accurately in real time, and realize the operation of the hydraulic support independently, which lays a foundation for improving the production efficiency of the fully mechanized mining face.
