液压支架是现代大型自动化煤矿工作面所采用的主要支护设备,它在工作面为作业工人及采煤机、刮板输送机提供一个安全的工作空间。液压支架的每个动作由安装在支架上的操纵阀控制实现,现在各种型号的液压支架操纵阀普遍采用手把裸露在外,没有闭锁装置和任何保护方式,存在操纵阀手把碰触后误动作情况,威胁到煤矿工作面安全生产;用可靠经济的限位装置方案,对其进行技术改造。

The hydraulic pressure support is the main supports and protections equipment which the modem large - scale automation coal mine working surface uses; it in the working surface for the work worker and the coal mining machine, the scraper conveyer provides a safe working space. Hydraulic pressure support each movement by installs on the support the control valve control realization, now each kind of model hydraulic pressure support control valve generally uses the handle to expose in outside, does not have any protection way, after has the control valve handle to bump touches the misoperation situation, threatens the coal mine working surface safety in production; The reliable economical spacing installment plan, carries on the technological transformations to it.
