[0002] To ensure production safety, on-site information collection and analysis are conducted at all times in flammable and explosive locations. Inspection robots, which can replace manual inspection tasks, have gradually entered the market in enterprises and institutions. Common types of rail-based inspection robots are ground-based inspection robots and mounted-rail inspection robots. Mounted-rail inspection robots are primarily used in machine rooms, substations, pipe corridors, and tunnels. They are equipped with cameras and sensors to conduct scheduled or real-time inspections.

[0003] A Chinese patent discloses a walking drive structure for a rail-mounted inspection robot, with publication number CN219172385U. The technical solution disclosed in the patent document is as follows: it includes a track, and two sliding grooves are symmetrically arranged in the length direction of the track; a power mechanism includes a drive motor that provides a power source for the walking of the rail-mounted inspection robot, and a drive gear is installed on the drive shaft of the drive motor.

The fan 272, through the shape design of the guide frame 271, can guide the airflow to the driving roller 25 during the movement of the driving frame 23, thereby realizing the function of auxiliary heat dissipation of the driving roller 25. The infrared temperature sensor 26 monitors the temperature of the driving roller 25 and feeds back the temperature data to the external controller. When the temperature reaches the preset value, the external controller controls the cylindrical fan 272 to work and deliver air to the surface of the driving roller 25, thereby realizing the function of blowing air to dissipate heat for the driving roller 25, avoiding the problem that the temperature of the driving roller 25 is too high and easily affects its service life.
