Background
The underground ore of the large mine is mostly transported by adopting a rail electric locomotive, and the accident that the ore carriage falls off the track can often happen in the running process of the electric locomotive, so that the reason for causing the ore carriage to fall off the track is usually multifaceted: firstly, the left and right spacing is enlarged due to the long-time running of the track; secondly, mechanical faults occur to the mine compartment wheel steering frame; thirdly, the speed of the electric locomotive is too fast. Usually, when the electric locomotive is driven locally by manpower, whether the electric locomotive falls off the track or not is judged mainly by the experience of a driver of the electric locomotive, and sometimes the locomotive forcibly pulls the fallen off-track mine compartment due to misjudgment of the driver, so that the damage degree of the mine compartment and the track is increased, and the mine transportation efficiency and the mine output are influenced. With the improvement of safety production, some mines are changed into unmanned electric locomotives to transport ores, and whether ore compartments fall off or not cannot be judged through sound and experience in the operation of the unmanned electric locomotives, so that the prior art needs to be improved.
