滚筒筒壳的开裂和变形是KJ型矿井提升机普遍存在的问题。我矿主付井绞车分别是苏产和国产的KJ系列的3m提升绞车,绞车筒壳的结构形式是对开式,对口用搭接板铆接形成一个整体,支环使用角钢。与筒壳之间用铆钉联接,筒壳与支轮之间采用螺丝联结。从1960年开始投入使用,先后出现过种种开裂现象,虽多次采取焊接、焊补、截缝、加固等措施均无济于事,且每次处理后所维持的时间越来越短,开裂的程度也越来越严
Cracking and deformation of drum shell is a common problem of KJ mine hoist. Mine pay mine winch are the Soviet-made and domestic KJ series of 3m hoisting winch, winch cylinder shell structure is open, riveted counterparts with a lap to form a whole, supporting the use of angle. Rivet connection between the shell and the shell, the shell and the wheel between the use of screw connections. Since it was put into use in 1960, various cracking phenomena have appeared one after another. Although many measures such as welding, welding, seaming and reinforcement are not available, and the time after each treatment is shorter and shorter, the degree of cracking is also More and more strict
