摘要
针对矿井目前已有运输方式(系统)存在的问题,设计了一种煤矿井下新型的辅助运输系统,该系统能够实现在起伏的多坡度巷道中,只利用一部绞车就可以实现矿车的往返运输。并根据煤矿安全生产要求,设计了不需防跑车装置的无轮矿车及有轮矿车的安全闭锁装置。同时,利用有限元分析软件对有轮矿车安全闭锁装置中制动爪强度进行了校核分析,分析结果表明制动爪完全能够承受矿车发生跑车时的冲击载荷。设计的成果应用于煤矿现场,降低了运输成本,减少了安全事故的发生,取得了较好的效果。
In order to solve the problem of transportation system in mine,this paper designed new auxiliary transportation system for underground mine.This system could realize round-trip of mining car by a winch in rolling roadway.For meeting mine safety requirement,safety lock device of no-wheel car and wheel car without catcher drag was designed.Strength of brake ratchet on safety lock device in wheel car was checked by finite element software.Result showed that brake ratchet could bear impact load when car sliding occurred.Application of this design in mine could reduce transportation cost and safety accident.
