A Maintenance Device for Track

This application proposes a rail maintenance device, which includes a main body, a driving mechanism, a camera, a suction mechanism and two marking mechanisms. Located in the main body and facing the track, the camera detects foreign objects on the track and the damaged position of the two rails on the track in real time; The suction mechanism is located in the main body and faces the track. When the camera detects a foreign object on the track, the driving mechanism stops moving, and the suction mechanism sucks the foreign object onto the track, so that the train can run safely on the track without being blocked by foreign objects; when the camera detects that any rail on the track has. In case of damage, the drive mechanism stops moving, and one or two marking mechanisms mark the damaged position of the rails on the track, to remind the inspector to make repairs.
