8750-65型吊斗铲是神华准能黑代沟露天煤矿重要的岩石剥离设备,它的运行直接影响着露天矿原煤的生产量。但是由于频繁的电气故障和润滑等原因,导致主绷绳出现断丝,而且日发严重。如果主绷绳突然断裂,大臂失去控制,那后果不敢设想。所以吊斗铲更换主绷绳刻不容缓。从安全和可操作性出发,研究了更换主绷绳的方法、起落大臂程序设置、如何进行保护、设备支护等技术要求,总结了一套严密的更换工艺。为吊斗铲顺利更换了主绷绳,避免了事故的发生,保证设备出动率。对吊斗铲维修保养有了重大突破。
The 8750-65 dragline is an important rock stripping equipment at Shenhua Zhineng Heidai Gou opencast mine and its operation has a direct impact on the production of raw coal in the open pit. However, due to frequent electrical failures and lubrication and other reasons, leading to broken wire rope occurred, and serious. If the main rope suddenly broken rope, arm out of control, then the consequences could not imagine. So drag bucket shovel replacement main rope without delay. From safety and maneuverability, the paper studied the methods of changing the main rope, the setting of the landing boom program, the technical requirements of how to carry out the protection and equipment support and concluded a rigorous replacement process. To dragline shovel successfully replaced the main rope, to avoid the accident, to ensure the equipment out rate. Dragline shovel maintenance has made a major breakthrough.
