车集煤矿主副井为立井提升,采用多绳摩擦轮式提升机提升,几乎每年都要进行首绳更换,截绳也自然是常事、主副井更换首绳运行几天后.往往冈承载负荷造成弹性拉伸,致使钢丝绳伸长,无法保证大小罐笼(或箕斗)同时到位,不但影响提升,还可能产生安全问题,所以必须进行截绳。 Main and auxiliary shafts of Cheji Coal Mine are upgraded by vertical shafts and are upgraded by multi-rope friction wheel elevators. The first rope replacement is carried out almost every year, and the cut-off rope is also a natural thing. After a few days of main and auxiliary shaft replacement first-line operation, Due to the elastic tension caused by the load, the elongation of the wire rope can not ensure that the size of the cage (or skip) is in place simultaneously, which not only affects the lifting but also may cause safety problems. Therefore, the rope cutting must be carried out.
