Coal mining working face equipment train traction device

The present invention relates to a coal mining working face (including ordinary mining working face, fully-mechanized mining working face and fully mechanized caving working face) equipment train traction device, which implements the mechanical traction or automatic traction of a stope face working face equipment train to create the conditions for realization of automatic working face. The equipment train traction device is powered by an emulsion pump station, operating valves are in centralized control, the system is simple, easy to operate and reliable to run, in the case of use of an electro-hydraulic valve for control, remote control or unattended operation can be achieved, and conditions for the realization of the automatic working face are created. The key technical solution is that: two groups of mechanisms called as hydraulic grippers in the equipment train traction device are used, and are respectively placed on front and back tracks of the traction device body, then the hydraulic grippers and the traction device body are connected into one body by a pull and push jack, when one group of the hydraulic gripper grips the track, the pull and push jack connected with the hydraulic gripper is used for pull or push to move the traction device so as to lead the equipment train to move.
