BC-1型穿孔机主卷扬筒,由于在工作过程中受到提升钢丝绳的磨擦,表面逐渐出现沟槽。新的卷扬筒一般工作3-4年后,中部沟槽深度就达10毫米以上。如采用电弧堆焊的修复办法,易造成筒体变形,两端轴颈轴心线移位等,同时需耗用大量的电焊条,并需要较长的修复工期。大冶铁矿经过多次研究和试用,改用筒体车削光刀后镶包钢板的方法,获得了较好的效果,具体施工过程如下:1.拆除卷扬筒两侧的传动齿轮和抱闸光轮,进行车削光刀,一般情况筒体外径保持880毫米,如中间留有部分 BC-1 type punching machine main winch drum, because in the course of work by lifting friction rope, the surface gradually groove. The new hoist cylinder general work 3-4 years later, the depth of the central trench reached 10 mm above. Such as the use of arc welding repair, easy to cause deformation of the cylinder, both ends of the shaft axis displacement, while the need to consume a large number of welding electrodes, and the need for longer repair period. After many times of research and trial use of Daye Iron Mine, the method of inlaying steel plate after turning the cutter body into the cylinder body has obtained good effect. The specific construction process is as follows: 1. Remove the transmission gear and the brake Light wheel, the turning knife, the general case of the outer diameter of the cylinder to keep 880 mm, such as the middle left part
