我矿主提升机系60年代国产的仿苏矿井提升机,近年来,主轴装置的卷筒切向键松动频繁,平均每3个月需更换一次。一个主轴装置的四付切向键价值在500元以上,更换一次主提升机需停机10h左右,对矿井生产影响很大。传统上更换切向键的方法是:将损坏的切向键从键槽取出后,测量键槽宽度,然后按键宽配制切向键,并截去长度余量部分,人力用大锤将切向键打进键槽。这种方法费工费时,更换四付切向键需5—6人操作10h以上才能完成,且键与键槽配合不好,易
In the past few years, miners hoisted the machine-made imitation Su-mine hoist made in the 1960s. In recent years, the mandrel-tangential key of the spindle device has loosened frequently and needs to be replaced every 3 months on average. A spindle device four pay tangential key value of 500 yuan or more, replace a main hoist to be shut down about 10h, a great impact on mine production. Traditionally, the method of changing the tangential key is to measure the width of the keyway after the damaged tangential key is removed from the keyway, and then press the key to make the tangential key and cut off the length margin. The human uses the sledgehammer to cut the tangential key Into the key slot. This method takes time and labor, the replacement of four to pay the key to 5-6 people to operate more than 10h to complete, and the key with the keyway is not good, easy
