副井绞车滚筒直径误差的处理方法与效果检验

主提升绞车两码滚筒直径在制作上存有误差,造成上、下两码罐笼在井口、井底的停止位置相差较大,不但人员上下罐笼时非常不方便,另外,当一码罐笼到达井口停车位置时,而另一码罐笼已经下回过多,促使钩头松弛发生侧翻现象,这样就容易造成钢丝绳打结或挂住其它井筒装备而埋下较大的安全隐患。经过计算,并考虑到接触间隙,决定在每块衬木下加垫厚度为1.5mm的垫片。通过检验效果验证:两码罐笼停止位置都控制在30mm的范围内。

The main lifting hoist two yard drum diameters have the error in the manufacture, causes the top and bottom two yards cages in the well head, the bottom of the well stop position difference to be big, when personnel high and low cage is not convenient, moreover, when a yard cage arrives at the well head parking position, but another yard cage the next time excessively were already many, urges the hook relaxation to have the side to turn the phenomenon, like this easy to cause the steel wire to tie a knot or to hang other well chamber equipment to lay down the big safe hidden danger. After the computation, and considered the contact gap, decided adds the pad thickness under each lining wood is the l.Smm filling piece. Through examination effect confirmation： Two yard cage stop position controls in the 30mm scope.
