Friction plates and brake discs are alternately arranged, the friction plates are installed in containing cavities in the two sides of a shell, and the brake discs are installed on a hollow shaft and have the braking state and the braking releasing state. The separation assembly is arranged on the brake disc and the friction plate and used for driving the brake disc and the friction plate to be rapidly separated from friction when braking is relieved. A temperature sensor of the heat dissipation assembly is installed on the shell, the temperature of the brake disc is detected in real time, an external air compressor is controlled to dissipate heat of the brake disc, and an output port of the external air compressor is connected to the lower left side of the brake disc of the containing cavity. The state indication assembly is installed on the shell and on the upper side of the brake disc and can stretch out or retract back to be used for representing the braking state and the braking release state. The hollow
