Track clamping braking device for mining transport vehicle

The utility model relates to the technical field of mine car transportation, in particular to a mine transport vehicle rail clamping braking device which comprises a rail, four rail wheels are connected to the top of the rail in a sliding mode, a bottom plate is installed among the four rail wheels, and a carriage is fixed to the top of the bottom plate. According to the rail clamping braking device for the mining transport vehicle, through cooperation of structures in the lifting assembly and the water diversion assembly, a supporting rod can be driven by an electric push rod through a moving plate to move up and down, so that the supporting rod can drive a braking block to make contact with a rail, and the braking effect is achieved; meanwhile, a limiting block is driven by a fixing block to move out of a waterproof groove, a drainage groove enters a water tank, and therefore water in the water tank can reach the brake block through the drainage groove, the brake block is cooled, deformation or serious abra
