The servo motor 11 is only used in this patent, and its structure and function are not improved. For the technicians in this field, its setting method, installation method and electrical connection method, as long as they are debugged and operated according to the requirements of its instruction manual, they will not be repeated here. The servo motor 11 is provided with a control switch matched with it. The installation position of the control switch is selected according to the actual use requirements, so that the operator can operate and control it conveniently;

[0022] In one embodiment, the cross section of the track 2 is arranged in an I-shaped structure, and the brake belt 4 is fixed to the upper part of the inner side of the track 2. Through the arrangement of the brake belt 4, it can directly contact with the brake block 7, thereby reducing the wear of the track 2.

[0027] Working principle:

[0028] When in use, firstly, the servo motor 11 is powered by the power supply on the frame 1. When the coal mine comprehensive mining working face equipment train needs to stop, the servo motor 11 is started to drive the gear 9 fixed at its output end to rotate. The rack 6 interlaced with the bottom of the frame 1 is meshed with the gear 9, and the end of the rack 6 facing the brake band 4 is fixed with a brake block 7. As the rack 6 pushes the brake block 7 close to the brake band 4, the end face of the brake block 7 is able to frictionally contact with the brake surface 12 on the inner side of the brake band 4, so as to achieve the purpose of stopping the frame 1. When the brake band 4 is severely worn, the worn brake band 4 is peeled off the track 2 by removing the hexagon socket bolts 13 interlaced and installed between the brake band 4 and the track 2, and then the new brake band 4 is replaced.
