摘要
现有液压支架卸载系统在操作中存在剧烈的冲击、振动现象,导致元件不必要损伤,致使卸载系统寿命降低。通过技术上的改进,实现了支架降柱之前必须使立柱下腔有效地卸压,较好地解决了这一问题。
Uninstall the existing hydraulic support system in operation there is severe impact,vibration,and that leads to unnecessary injuries components, resulting in reduced life expectancy to uninstall the system.Through technical improvements,the realization of the stent must be made before descending column column inferior vena effective relief,a better solution to this problem.
