Mine inclined roadway buffer vehicle stopper

Abstract

A mine inclined roadway buffer vehicle stopper comprises a vehicle stopping fence and is characterized in that an air cylinder base is fixed to the top of a roadway, sliding blocks which are arranged on the two sides of the air cylinder base and can slide are arranged on the air cylinder base, the sliding block on each side of the air cylinder base is connected with a piston of an air cylinder, one end of a traction rope passes a pulley and is connected with the vehicle stopping fence, the other end of the traction rope is connected with the sliding blocks, a plurality of steel tubes are arrayed in an up and down mode and connected together through drawing chains to form the vehicle stopping fence, each steel tube penetrates through a steel wire rope, and the two ends of each steel wire rope are fixed through a pressing plate which is fixed to a base plate and provided with rope grooves. The mine inclined roadway buffer vehicle stopper has the advantages that compressed wind driving of an underground wind compression system is used, no other power source needs to be additionally arranged, the vehicle stopping fence enables the steel tubes to be arrayed together along with the traction of the traction rope, and the installation height of the vehicle stopping fence is reduced. The protection effect is good due to the fact that energy is absorbed through buffering, and the number of the pressing plates is increased or decreased according to the actual gradient. The mine inclined roadway buffer vehicle stopper is simple in structure and convenient to install.

Description

technical field [0001] The invention relates to a supporting device for a mine underground inclined roadway transportation machine, in particular to a buffer stopper capable of blocking a vehicle when a sports car accident occurs during transportation. Background technique [0002] Inclined lane winch transportation is an important part of coal mine underground transportation, and once a sports car accident occurs, it will cause injury and loss to people and equipment. Article 370 of the "Coal Mine Safety Regulations" stipulates: Install a sports car protection device in the inclined shaft that can stop the vehicle from breaking the rope or decoupling. The device must be normally closed and can only be opened when the vehicle is released. At present, there are vertical car barriers and horizontal car barriers used in inclined lanes, both of which are rigid barriers. Field practice proves that this rigid car-stopping device does not have a good car-blocking effect. They are ...

AI Technical Summary

Problems solved by technology

Field practice has proved that this rigid car-stopping device has a poor car-blocking effect, and is damaged or knocked into the air. The protective effect is not good. Therefore, it is urgent to provide a safe and effective protective device to prevent greater damage to the mine.
