1问题的提出啃轨是门吊使用中常见故障,主要由于门吊在运行中车轮偏斜运行,车轮边缘与走行钢轨之间产生严重摩擦。我公司大部分货场都使用20T门吊,由于架设比较早,使用时间较长,在运行过程中多台门吊出现大小车不同程度的啃轨现象,车轮边缘和钢轨间严重磨损,这些导致小车运行机构的运行阻力增大、电动机功率额外损耗、传动部件受力增加,时间长将导致车轮磨损超限报废,如果不及时进行更换,严重的将危及安全,影
1 The question put forward Gnawing rail is a common failure in the use of door hanging, mainly due to the door hanging in the operation of the wheel deflection operation, the wheel edge and walking rail between the serious friction. Most of the freight yard of our company uses 20T door hanger. Due to the earlier erection and long service time, many trolley hangers of different degrees in the course of operation run out of gear and cause severe wear between the wheel rim and the rail. The running resistance of the operating mechanism increases, the motor power loss, transmission components increased force, a long time will lead to wheel wear overrun, if not replaced in a timely manner, will seriously threaten the safety of the shadow
