Problems solved by technology
[0003] In the aforementioned mechanical anti-sports car patented technology, the use of anti-vehicle claws, brake claws or backstop rods to realize the braking of the mine car may easily cause the mine car to overturn or derail, and due to the complex laying conditions of the track sleepers, it is easy to cause braking failure
Clamping or holding rail brake devices are relatively safe and reliable, but the existing technology mostly uses overspeed detection to control the start of the brake device. The structure of the device is relatively complicated, and the key technology is the setting of the critical speed. Large, the braking kinetic energy of the mine car must be large, and the braking effect is difficult to guarantee. If the setting is too small, it is easy to cause false start of the braking device. It is difficult to set the critical overspeed value, which greatly limits the practicability of this type of device.
However, the anti-running device of the mine car brake is realized by controlling the brake shaft gripper through the handle, which has a low degree of automation and is not suitable for automatic anti-running during the operation of the mine car.

Abstract
The invention discloses a rail clamping self-locking type anti-running device for a mine vehicle. The device comprises a left braking rocker arm, a right braking rocker arm, left fixed angle iron, right fixed angle iron, a braking rocker arm hinge shaft, a left rocker arm sliding sleeve, a right rocker arm sliding sleeve, a left braking claw connecting block, a right braking claw connecting block, a left braking claw connecting block pin shaft, a right braking claw connecting block pin shaft, a left braking claw truss, a right braking claw truss, a left braking inner claw, a left braking outer claw, a right braking inner claw, a right braking outer claw, a left suspension rope, a right suspension rope, a left braking rope and a right braking rope. According to the device, a mechanical structure is adopted, so that the device is simple in structure, convenient to implement, low in manufacturing cost, easy to maintain and long in service life; a rocker arm mechanism self-locking principle is utilized, and the mine vehicle is braked in a rail clamping way, so that the risks of turnover, derailment, braking failures, secondary damage and the like are eliminated, and running accidents of the mine vehicle can be effectively prevented.
Description
technical field [0001] The invention relates to mine auxiliary transportation equipment, in particular to an anti-running device for underground auxiliary transportation mine cars in coal mines. Background technique [0002] Sports car accidents account for a considerable proportion of auxiliary transportation accidents in coal mines. Once a sports car accident occurs, it often causes heavy losses of life and property. Therefore, preventing sports cars has always been one of the key tasks in coal mine safety production management. The "Coal Mine Safety Regulations" issued by the State Coal Mine Safety Supervision Bureau in 2009 clearly stipulates the car stop and anti-running device in the inclined roadway, and requires that the inclined shaft must be equipped with "one slope and three stops" anti-running device. At present, the anti-sports car device has a history of more than ten years in China, and there are various types. The more common ones are manual type, impact type...
