Problems solved by technology
But in fact, when an accident occurs, this kind of braking response is slow, the claws cannot fall in time or the claws cannot completely and effectively block the sleepers, and there is a great safety hazard when the vehicle brakes and stops.

The invention provides a hydraulic brake block type brake shuttle car. The brake shuttle car comprises a brake block, a brake arm, a piston rod and a mounting bracket, wherein the brake block is mounted at one side of wheels, and is fixedly mounted on the brake arm through a pin shaft; one end of the brake arm is mounted on the piston rod, and the other end is mounted on the mounting bracket; a spring is arranged in the piston rod; a cylinder jacket is arranged at the outer side of the spring; and the mounting bracket is fixedly mounted on the frame. Braking force is directly acted on the wheels, so that the parking brake reliability is greatly promoted, the response to such emergencies as rope break is fast, and the performance is reliable; and the hydraulic brake block type brake shuttle car is strong in adaptability, can be parked in any place including a turnout, and relatively reduces the paving requirements of rail sleepers.
Description
technical field [0001] The invention relates to the technical field of brake systems for mine auxiliary transport traction shuttle cars, in particular to a hydraulic brake shoe type brake shuttle car. Background technique [0002] The endless rope continuous tractor is a kind of ordinary rail transportation equipment pulled by steel wire rope in the coal mine underground roadway, and the tractor must have a braking function to prevent the occurrence of accidents such as slipping cars and sports cars due to broken wire ropes. [0003] The braking system of the existing shuttle car generally adopts the claw type, and the steel wire rope is wound on the winch drum, and the claw is lifted through the ring on the claw, and the rope head is fixed on the vehicle frame. When the wire rope breaks accidentally, the brake pawl falls due to the lack of support of the rope, and gets stuck between the sleepers of the track to realize braking and parking. But in fact, when an accident occ...
