摘　　要：黑岱沟露天煤矿在用的8750-65型迈步式吊斗铲右上主绷绳严重断丝后,无法按照设备制造厂家原设计更换工艺进行检修。为了解决这一难题,提出了高空作业直接更换主绷绳和利用履带吊下放大臂更换主绷绳等解决方案,通过大胆假设、理论分析及模拟计算等方法,研究了在此极端情况下新的吊斗铲主绷绳更换工艺,最终确定并成功实施了"履带吊结合吊斗铲自身能力起放大臂更换主绷绳工艺"。After the serious breakage of the upper right main guy rope, 8750-65 dragline is impossible to carry out maintenance according to the original design and replacement process of the equipment manufacturer. In order to solve this problem, the article puts forward replacing the main guy rope directly during overhead work and using crawler crane to lower the boom to replace the main guy rope solution and so on.Through the bold hypothesis、the methods of theoretical analysis and numerical simulation, we study new dragline main guy rope replace process in the extreme cases, and successfully implement the "crawler crane combined with the ability of dragline lifting and lowering boom to replace the main guy rope technology".
