Auxiliary braking speed reducer for explosion-proof rubber-tyred vehicle

Abstract

The invention relates to an auxiliary braking speed reducer for an explosion-proof rubber-tyred vehicle, and discloses an auxiliary braking structure which can perform auxiliary braking on the rubber-tyred vehicle through an electromagnetic chuck, reduce abrasion between a vehicle body and equipment during braking and prolong the service life. The auxiliary braking speed reducer is characterized in that one end of a rotating rod is arranged on a fixing base through a rotating lug, a fixing groove is formed in the fixing base, a fixing frame is arranged at the other end of the rotating rod, the two ends of the fixing frame are bent in the direction away from the rotating rod, the two ends of the touch rotating roller are correspondingly arranged at the two ends of the fixing frame, one end of a pneumatic telescopic rod is arranged on the rotating rod through a hinge lug, and a rotating base is arranged at the other end of the pneumatic telescopic rod. A protection plate is arranged at the top of an electromagnetic chuck, a plurality of through grooves are formed in the protection plate at equal intervals, a plurality of damping springs are arranged between the protection plate and the electromagnetic chuck, the two positioning plates are arranged on the two sides of the electromagnetic chuck respectively, the fixing plates are perpendicularly arranged on the positioning plates, and the fixing plates are flush with the protection plate.

[0002] The trackless explosion-proof rubber-tyred vehicle is a commonly used transportation equipment in underground mines. At present, due to the heavy weight of the rubber-tyred vehicle itself, the braking distance of the vehicle is relatively long under the action of inertia when braking, and the braking effect is poor. When going downhill, the vehicle will still slide for a long distance after the tires are locked, and the existing braking structure used to assist the braking of the rubber-tyred vehicle will be in contact with the rubber-tyred vehicle during braking. The car body has direct contact with collision and friction, and the friction is relatively large. During long-term use, the car body and the car-blocking structure of the rubber-tyred car will have serious wear and tear, and the service life is low

[0003] The notification number CN210174835U discloses an auxiliary braking device for a vehicle and the vehicle. The auxiliary braking device of the vehicle includes a brake plate and a linear drive connected to the vehicle body. The linear drive is connected with the brake plate to drive the brake plate along a straight line. The axis of the driving member moves, and the auxiliary braking device has a working position and a non-working position. In the working position, the brake plate is extended to contact the ground. When the brake pads rub against the ground violently, the brake pads are prone to serious wear and the service life is low.
