[0040] like Figure 1-6 As shown, the present invention first places the entire device on the coal mine track, and energizes the inside of the driving chassis 17 by starting the controller 30. The driving end of the driving chassis 17 rotates to transmit power to the shaft 18, and the rotation between the gears inside the shaft 18 transmits power to the driving shaft 19, thereby driving the roller 4 to move on the track. At this time, the track surface can be cleaned by the cleaning water pipe 8 during the entire movement. If the leveling roller 29 encounters a large obstacle during the movement, the sleeve rod 26 connected to the leveling roller 29 is convenient to move upward, and the sleeve rod 26 connected to the leveling roller 29 is convenient to move upward. During the process, the block 27 will be driven to move, thereby deforming the reset spring 31 inside the elastic member 28 connected thereto. Since the reset spring 31 has a certain elastic potential energy, it drives the bottom plate 32 at its bottom to move upward. At this time, the magnetic pole block 35 at the bottom of the bottom plate 32 is separated. At this time, a signal will be transmitted to the controller 30, thereby transmitting the signal to the drive chassis 17 and causing the internal drive device to stop urgently. The program set in the controller 30 is used to scrape or polish the impurities sticking on the track in this area, and finally the cleaning water pipe 8 is used to clean the track surface.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
