Mining inclined drift sliding-down protection device

The invention discloses a mining inclined drift sliding-down protection device, and particularly relates to the technical field of mine car protection. A mounting cylinder; a support shaft; a front wheel; a rear wheel; a balancing weight; a pull ring; the braking part comprises a fixed disc; a notch; a movable disc; a clamping block; and the driving assembly is used for driving the two movable discs to move towards the two fixed discs respectively after the balancing weight swings downwards, so that the clamping blocks can be clamped into the notches. When the balancing weight rotates downwards, the braking part is triggered to act, then the movable disc moves towards the fixed disc until the clamping block is clamped in the notch, the supporting shaft is fixed and does not rotate, so that the front wheel can be braked, and compared with an anti-sliding device in the prior art, the anti-sliding device can brake the vehicle body in an extremely short time, so that the service life of the vehicle body is prolon
