悬吊临时支护装置沿固定于巷道顶板的轨道行走,是一种快速护顶装置,兼具一定的物料运输作用,其快速驻车系统对于保证整机的安全性具有重要作用。设计了快速驻车机构的机械结构,采用双边连杆框架结构,结构紧凑且安全性好。驻车机构旁路设置了液控二位二通阀,分析了该阀的2种液压控制原理。通过试验发现,采用独立控制油的方式能够实现驻车机构的快速动作,达到快速驻车的目的。
Suspension temporary support device is fixed along the roadway roof track orbit, is a fast escalator device, both the role of certain material transport, the rapid parking system to ensure the safety of the whole machine plays an important role. The mechanical structure of the quick parking mechanism is designed. The structure of the double linkage frame is compact and the safety is good. Parking mechanism bypass set up two-way two-way valve, analyzed the two kinds of hydraulic control valve principle. Through the experiment found that the use of independent control of the oil can realize the parking mechanism fast action, to achieve the purpose of fast parking.
