摘要
液压支架为实现各种动作,装设了较多的液压缸。这些液压缸的动作均由操纵阀来控制,为方便井下实际操纵,操纵阀手把通常布置在人员易触及的位置,无任何安全限位和闭锁保护,存在手把误动作的隐患。提出的液压支架操纵阀手把中位闭锁装置的设计方案,具备方便、安全、实用的特点,并已投入井下生产实践。
In order to realize all kinds of action,hydraulic supports installed more hydraulic cylinders.The hydraulic cylinders by the control valve to control the movements of,for the convenience of the underground actual manipulation,control valve hand to decorate usually accessible location in personnel,without any safety limit and block protection,to hand the misoperation of risk.The hydraulic support control valve handle in a locking device design,have the characteristics of convenient,safe,practical,and has put into downhole production practice.
