New Head Rope Replacement Technique of Mine Frictional Hoist and Application

介绍了一种矿井摩擦式提升机首绳更换新工艺,主要是用专用U型卡将新旧绳卡接在一起,开动绞车利用旧绳带动新绳将新绳敷设至井底,依靠在井架上的液压调绳装置和快速锁绳器将旧绳替换成新绳,然后反向开车将新旧绳替换。此方法大幅度减少了大型临时设施的使用和井筒作业的安全风险,缩短了施工时间,为提升绞车更换首绳方面提供了相关参考。

A new head rope replacement technique was introduced for the mine frictional hoist.A special U type fastener would be applied to fasten the used and new ropes together.With the winch in operation,the used rope could drive the new rope down to the mine shaft bottom.With the hydraulic rope adjustment device and the fast rope locker on the mine shaft headframe,the used rope would be replaced by the new rope and then the used and new rope replacement could be conducted with the reversed operation of the hoist.This method could highly reduce the application of large temporary facilities and the safety risks of the operations in the mine shaft and could reduce the construction time.This method could provide the related references to the head rope replacement of the mine hoist.
