[0002] Railway tracks are referred to as rails, iron tracks, and tracks. They are used on railways and work with switches to allow trains to run without turning. Tracks are usually composed of two parallel steel rails fixed on sleepers with ballast under the sleepers. The main function of railway tracks is to support the weight of the train, guide the direction of the train, and maintain stable operation of the train. Guide rollers are key components for guiding track vehicles to run stably. They are installed on the bottom of track vehicles. They roll along the tracks to help track vehicles run and turn.

[0003] The guide rollers used in subway tracks travel on the tracks through their own power. However, during the travel, they may encounter uneven track lines and worn rails. Uneven track lines and severely worn track lines may cause the friction between the guide rollers and the tracks to decrease, which may easily cause the guide rollers to lose control and cause derailment. As a result, the guide rollers have poor stability during travel, and the staff need to re-place the guide rollers on the tracks, which affects work efficiency to a certain extent.
