煤矿井下长距离设备列车适应性研究

Adaptation research of Long Distance Equipment Train in Coal Mine

为了解决煤矿井下传统绞车牵引设备列车采用钢丝绳牵引、高空悬挂单轨吊带来的安全风险,避免设备列车在运输过程中发生自滑移、掉道、翻车、跑车、钢丝绳断裂等事故,研制KDYZ40-40/2000矿用电控液压移动列车组,为综采工作面动力控制设备提供安全保障,核算长距离设备列车载重、锚固牵引力、推移系统拉力以及自动伸缩管缆装置设计中弹簧制动器的适应性,重点研究了自移设备列车在±12°坡道上的适应性。结果表明:该设备列车组能够适应±12°坡道的工况条件,取消绞车牵引、高空悬挂单轨吊以及铺设轨道,有效保证安全高效生产。

There are safety risks caused by wire rope traction and high-altitude suspension monorail cranes in the traditional winch traction equipment trains.To avoid the accidents in the transportation process of the equipment trains,including self-slip,derailment,rollover,sliding,and wire rope breaking,KDYZ40-40/2000 mining electronic control hydraulic mobile train unit was developed to provide safety guarantee for the power control equipment on fully mechanized mining face.The study calculated the weight of the long-distance equipment trains,anchoring traction force,pulling force of pushing system,and the adaptability of spring brake in automatic telescopic pipe and cable device,and it focused on the adaptability of the self-moving equipment train on the±12°ramp.The results show that the train unit can adapt to the working conditions of±12°ramp.Eliminating winch traction,high-altitude suspension monorail crane,and tracks,effectively guaranteed the safe and efficient production.
