气动信号装置

Abstract

The utility model relates to a signal field specifically is a pneumatic signal device in the pit, including two sets of above the same signal liaison organizations of structure, every group signal liaison organization includes that one end communicates the inflator on air supply in the pit, the flexible slip in inside piston and the spring stationary blade of inflator, be fixed in spring stationary blade one side and support the reset spring of tight fit with the piston, be fixed in the catch bar that spring stationary blade opposite side just stretches out another terminal surface of inflator, be fixed in the hammer that strikes of catch bar tip, and with strike the hammer matched with bell body, it has the exhaust hole to be located to open on the inflator between piston and the spring stationary blade, install the control switch of control air supply on the air inlet of inflator, the inflator air inlet department of every group signal liaison organization is linked together through the trachea. Pneumatic signal device for the signal device of non -transformer, is applicable to signal contact more than two places or the two places, has reduced staff's electric shock hidden danger, ensures the personal safety.
本实用新型涉及井下信号领域,具体是一种气动信号装置,包括两组以上结构相同的信号联络机构,每组信号联络机构包括一端连通于井下气源上的气筒,伸缩滑动于气筒内部的活塞以及弹簧固定片,固定于弹簧固定片一侧且与活塞抵紧配合的复位弹簧,固定于弹簧固定片另一侧且伸出气筒另一端面的推动杆,固定于推动杆端部的敲击锤,以及与敲击锤相配合的铃体,位于活塞和弹簧固定片之间的气筒上开有排气孔,气筒的进气口上安装有控制气源的控制开关,每组信号联络机构的气筒进气口处通过气管相连通。本实用新型所述气动信号装置,为无电源的信号装置,适用于两地或两地以上信号联络,减少了工作人员的触电隐患,确保人身安全。
