Abstract
The utility model discloses a rail mining car comprising a car hopper, a chassis, a front wheel pair, a rear wheel pair and a brake device. Brake holes are arranged on the wheels of the rear wheel pair. The brake device comprises a brake shaft, a shaft pushing compressed spring, a locking rod and a locking spring. The two ends of the shaft pushing compressed spring are respectively pressed against the brake shaft and the chassis, and a structure that the brake shaft can be pushed by the shaft pushing compressed spring to extend into the brake holes is formed. The locking rod is hinged with the chassis to form a lever structure. The power arm of the lever structure extends out of the front end of the mining car, and the end part of a resisting arm is provided with a clamping groove for clamping the brake shaft and limiting the slide of the brake shaft. The two ends of the locking spring are respectively pressed against the chassis and the locking rod, and a structure that the locking state of the brake shaft by the locking rod can be kept by the locking spring is formed. When the mining car runs off the rails and runs into a car parapet, the locking rod is pushed by the car parapet to unlock the brake shaft, and the brake shaft extends into the brake holes under the action of the shaft pushing compressed spring. The wheels of the mining car are stopped. Thus, the wheels can still be stopped when the car parapet is disabled.

The utility model content
In view of this, the utility model provides a kind of rail mine car, this mine car in when, derailing accident taking place and running into arrester, the automatically starting emergency brake device, make the tramcar wheel stall, actv. has prevented that it from making because of load carrying ability is excessive under the arrester failure conditions to be continued sport car and works the mischief.
Rail mine car of the present utility model comprise wagon box, base, front-wheel to, trailing wheel to and brake equipment, the right wheel upper edge shaft axis direction of described trailing wheel is provided with brake hole; Described brake equipment comprises brake axle, push shaft stage clip, locking lever and lock spring, mode and the base bearing fit of described brake axle reciprocatingly sliding over against brake hole, and the two ends of push shaft stage clip are withstood brake axle and base respectively; The hinged formation lever construction of described locking lever and base, the power arm of lever construction stretches out the mine car front end, the draw-in groove that snaps in brake axle and limit its slip is set on the resistance arm, and lock spring is arranged between base and the locking lever in the mode that its prestress can keep locking lever restriction brake axle to slide.
Further, over against brake hole the brake axle mounting hole is set on the described base, the brake axle middle part is provided with and the round boss of brake axle mounting hole bearing fit forms the interior shaft shoulder and the outer shaft shoulder, near the interior shaft shoulder one end, its two ends are withstood the brake axle mounting hole bottom and the interior shaft shoulder respectively to the push shaft compression spring sleeve at brake axle;
Further, described lock spring is a torsion spring, and lock spring is enclosed within on locking lever and the base pivotally attached jointed shaft, and its two ends are withstood locking lever and base respectively;
Further, also comprise cross bar, described cross bar two ends difference captive joint and trailing wheel are to two cooresponding two locking lever power arm ends of wheel.
The beneficial effect of utility model: rail mine car of the present utility model comprise wagon box, base, front-wheel to, trailing wheel to and brake equipment, the right wheel upper edge shaft axis direction of described trailing wheel is provided with brake hole; Described brake equipment comprises brake axle, push shaft stage clip, locking lever and lock spring, mode and the base bearing fit of described brake axle reciprocatingly sliding over against brake hole, and the two ends of push shaft stage clip are withstood brake axle and base respectively; The hinged formation lever construction of described locking lever and base, the power arm of lever construction stretches out the mine car front end, the draw-in groove that snaps in brake axle and limit its slip is set on the resistance arm, lock spring is arranged between base and the locking lever in the mode that its prestress can keep locking lever restriction brake axle to slide, when mine car generation sport car bump arrester, arrester promotes locking lever, make the draw-in groove disengaging brake axle on the locking lever make the brake axle release, brake axle stretches into brake hole under the effect of push shaft stage clip, make the right wheel stall of mine car trailing wheel, even make it under the situation that arrester lost efficacy, also can stop, effectively improved the safety of inclined gallery hauling operations.
