anti-car device

Abstract

The invention relates to a coal mine safety device, in particular to an anti-sliding device. The anti-sliding device comprises a centralized control box and an intercepting device, the centralized control box is located above the intercepting device in the ascending direction of the inclined roadway, a speed monitoring device is arranged on the centralized control box, and the centralized controlbox is electrically connected with the speed monitoring device; the intercepting device comprises a supporting base, a first sliding shaft, a second sliding shaft, a front wheel car stopping block, arear wheel car stopping block, a first spring, a second spring, an electric hydraulic push rod and a sliding rod, wherein the first sliding shaft, the second sliding shaft, the front wheel car stopping block, the rear wheel car stopping block and the first spring and the second spring are arranged in bilateral symmetry, and the electric hydraulic push rod and the sliding rod are in electric connection. When the front wheel car stopping block slides, the rear wheel car stopping block is driven to stop front and rear wheels of a mine car at the same time; the situation that when blocking equipment blocks a mine car body, the mine car body deforms or is damaged, so that equipment loaded in a mine car is damaged by squeezing is avoided, and rollover and derailment accidents caused by only blocking front wheels of the mine car are also avoided.

Description

technical field [0001] The invention relates to a coal mine safety device, in particular to an anti-car device. Background technique [0002] In the actual production process of the mine, the biggest hidden danger of inclined lane transportation is the occurrence of sports car accidents, that is, during the transportation of inclined lanes, broken ropes, out-of-stock chains, misoperations, etc. cause the vehicle to run into a sports car. Various car stoppers are set in the alley to prevent the vehicle from sliding down. When the car stopper is used to block the body of the mine car, due to the large impulse of the sports car, it is easy to cause deformation or damage to the body of the mine car, which not only increases the mine car and The maintenance cost of the car stopper is also easy to cause the equipment loaded in the mine car to be crushed due to the deformation of the mine car body. When the car stopper is used to block the wheels of the mine car, it is easy to caus...

The maintenance cost of the car stopper is also easy to cause the equipment loaded in the mine car to be crushed due to the deformation of the mine car body. When the car stopper is used to block the wheels of the mine car, it is easy to cause Overturning and derailment accidents occurred in mining vehicles, which increased the risk of braking
