采用立井开拓方式的矿井在建井期间,当由立井井筒转入平巷施工时,提升方式也要由吊桶提升改变成罐笼提升,并多采用钢丝绳罐道。《煤矿安全规程》第336条中规定:“采用钢丝绳罐道时,每100米钢丝绳的张紧力不得小于1吨……”。为了获得足够的张紧力,现行方法有挂重锤砣坠紧、花篮螺栓拉紧、稳车拉紧、液压螺杆拉紧式钢丝绳罐道拉紧装置拉紧等。这几种方法虽都切实可行,但感到不够方便,因为有的需加深井底水窝和铸造几十吨锤砣,有的方法仅适用于浅井而且调整费力,有的方法需占用稳车和
During the well construction period, when the well shaft is switched from the shaft to the laneway, the lifting mode should also be changed from the bucket lifting to the cage hoisting and the wire rope channel should be used more. “Coal Mine Safety Regulations” Article 336 states: “When using rope cans, every 100 meters rope tensioning force of not less than 1 ton ... ...”. In order to obtain sufficient tension, the existing methods are hanging heavy hammer 砣 tight, flower basket bolts taut, steady vehicle taut, hydraulic screw tightening rope tightening device such as tightening. Although these methods are practical, but not convenient enough, because some need to deepen the bottom of the nest and casting dozens of tons of hammer, and some methods only apply to shallow wells and adjust the labor-saving, and some methods need to stabilize the car and
