介绍了综采工作面液压支架操作手把防护装置的设计及改进。防护装置固定在液压支架阀组两侧,通过U形挡圈限制操作手把转动,避免了人员行走及搬运物体时触碰操作手把造成液压支架误动作现象。 This paper introduces the design and improvement of the protective device for the operating handle of hydraulic support in fully mechanized coal face. The protective device is fixed on both sides of the hydraulic bracket valve group and restricts the rotation of the operating handle through the U-shaped circlip, which avoids the phenomenon that the hydraulic bracket is inoperable when the operating handle is touched by the personnel walking and handling the object.
