Inclined roadway rail transport portal vehicle blocking mechanism

Abstract

The invention relates to an inclined roadway rail transport portal vehicle blocking mechanism. The mechanism comprises an outer end upright post, a vehicle blocking cross bar, an inner end upright post, a driving cylinder, a control device, a compressed air pipeline and a control electromagnetic valve, wherein the outer end upright post and the inner end upright post are main body supporting pieces; the vehicle blocking cross bar is arranged on the outer end upright post and the inner end upright post and is a vehicle blocking main body piece; the driving cylinder connected with the tail end of the vehicle blocking cross bar is arranged on one side of the inner end upright post, can control a vehicle blocking station and a releasing station of the vehicle blocking cross bar and is connected with the compressed air pipeline through a pipeline; the control device and the control electromagnetic valve are arranged in parallel on a pneumatic pipeline connected to the compressed air pipeline; and the outer end upright post and the inner end upright post are vertically arranged on the two sides of a rail close to the side wall of a roadway, so that the safety factor is improved. The mechanism has a simple integral structure and high stability and reliability, is convenient to install, operate and use, and has high adaptability to the roadway.

Description

technical field [0001] The invention relates to a protective device for a sports car of an inclined track transport roadway under a coal mine, in particular to a door-type vehicle-blocking mechanism for inclined track transport. Background technique [0002] There are a large number of inclined roadways in coal mines. In the inclined roadways, the gangue and support materials mined by rails need to be loaded and transported by mine cars. The transportation of inclined road mine cars is drawn by the winch on the upper part of the roadway. Sports on the track, sometimes there will be accidents such as casualties and equipment damage due to the breakage of the steel wire rope. Article 370 of the "Coal Mine Safety Regulations" clearly stipulates that "In the inclined shaft roadway, install a sports car protection device that can prevent the vehicles from breaking the rope and decoupling." , set up a car barrier that can prevent unlinked vehicles from continuing to go down, and ...

[0002] There are a large number of inclined roadways in coal mines. In the inclined roadways, the gangue and supporting materials mined by rails need to be loaded and transported by mine cars. Sports on the track, sometimes there will be accidents such as casualties and equipment damage due to the breakage of the steel wire rope.

Article 370 of the "Coal Mine Safety Regulations" clearly stipulates that "In the inclined shaft roadway, install a sports car protection device that can prevent the running of broken ropes and uncoupled vehicles." According to the length of the inclined roadway, each mine will set up a vehicle barrier at different positions. The current vehicle barrier generally adopts a vertical pull type or a flexible mechanism. After investigation, there are two types of barriers. Both methods need to make design brackets and install hoisting winches. In the case of large mine ground pressure and severe roadway deformation, roadway deformation has a great impact on the mechanism. At the same time, due to height restrictions, the mechanism needs to be dismantled and erected when transporting large equipment. Temporary safety protection device greatly affects the efficiency and safety of transportation
