Keyword:  提升绳长度误差滚筒单层缠绕双圆柱竖井钢丝绳老矿井绞车提升容器;
Abstract: 开滦矿务局钱家营矿在多年运行经验的基础上总结出了竖井双圆柱滚筒绞车提升绳长度调整的经验,该经验对防止现存的一些没有罐窝的老矿井的蹾罐事故和提高这些老矿井的生产效率都是有效的,文章从理论和实践两个方面分析了出现提升绳过短或过长,提升绳异长(俗称瘸腿,包括短瘸腿、长瘸腿和异瘸腿)的原因和调整方法,其中包括单层缠绕的和双层缠绕的双圆柱滚筒绞车的提升绳长度的调整,并以开滦矿务局唐山矿八号井单层缠绕的双圆柱滚筒绞车的提升绳异瘸腿的调整为例进行了计算和调整。文章最后还总结出减少提升绳长度误差的三点措施,并指出,当提升绳长度误差(过长、过短及各种瘸腿)值在50mm 以內时,可以暂不调整,因为这时对安全和生产的影响不大。
