矿山立井提升钢丝绳更换装置的研究与应用

Research and application of wire rope replacement device for mine shaft hoisting

矿井提升设备是联系矿井井下与地面的“咽喉”,在矿井生产中具有重要地位。本文以山西煤炭运销集团保安煤矿主立井箕斗提升系统为例,介绍了一种快速、安全的更换提升钢丝绳的设备和方法,即电液驱动式煤矿立井提升机钢丝绳更换装置。该装置采用2台电机驱动上下两条履带运行,液压油缸夹紧上、下履带,履带上固定有高分子摩擦衬块,上、下两组衬块夹紧钢丝绳后,上、下履带电机驱动履带运转,实现连续更换提升钢丝绳。实践表明,该技术缩短了钢丝绳更换时间,提高了更换过程中的安全性,广泛适用于各类钢丝绳的更换。

Mine hoisting equipment is the'throat'connecting the underground mine and the ground,which plays an important role in mine production.Taking the main shaft skip hoisting system of Baoan Coal Mine of Shanxi Coal Transportation and Marketing Group as an example,this paper introduces a fast and safe equipment and method for replacing the hoisting wire rope,that is,the electro-hydraulic driven coal mine shaft hoist wire rope replacement device.The device uses two motors to drive the upper and lower tracks,and the hydraulic cylinder clamps the upper and lower tracks.The track is fixed with a polymer friction lining block.After the upper and lower lining blocks clamp the wire rope,the upper and lower track motors drive the track to run,and realize the continuous replacement of the hoisting wire rope.Practice shows that this technology shortens the replacement time of wire rope,improves the safety in the replacement process,and is widely used in the replacement of various wire ropes.
