Underground inner wall supporting protection device for coal mine roadway

Abstract

The invention relates to the technical field of coal mine roadway supporting protection, in particular to an underground inner wall supporting protection device for a coal mine roadway. The underground inner wall supporting protection device comprises a first sliding rail, a second sliding rail, installation mechanisms, a squeezing mechanism, supporting protection mechanisms, anchoring mechanismsand position-limiting mechanisms. According to the underground inner wall supporting protection device for the coal mine roadway, the supporting protection mechanisms are arranged at the tops of the first sliding rail and the second sliding rail, ascending and descending of the supporting protection mechanisms are driven through corresponding gear screw rod transmission components, roadway top supporting protection is conveniently performed, and meanwhile, moving of the supporting protection mechanisms is also conveniently performed; the anchoring mechanisms are arranged at the tops of the twosides of the first sliding rail, the roadway is anchored through corresponding detachable anchor rods, and meanwhile, checking of excursion of the anchor rods is conveniently performed through a corresponding flexible connection mode; and when the underground inner wall supporting protection device for the coal mine roadway is used, the position-limiting mechanisms are arranged on the anchoring mechanisms, by means of corresponding toothed bar position-limiting structures, position-limiting is conveniently performed on the anchoring mechanisms, the anchoring mechanisms are avoided from generating excursion or looseness, and the corresponding anchoring effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway support, in particular to an underground inner wall support device for coal mine roadways. Background technique [0002] As a traditional energy source, coal has always occupied a large proportion in my country's national economy. With the construction of modern mines, it is a major focus of safety issues to ensure the safety and smoothness of roadways when dealing with various geological environments underground. There are various roadways in coal mines with many names, such as main lanes, return air lanes, transportation level lanes, auxiliary lanes, etc. Among them, the main function of the main roadway is for ventilation and transportation, the air return roadway is used for excavation, development, and the return air of the coal mining face, the transportation level roadway is used as a level roadway for transportation, and the auxiliary roadway is used as an auxiliary roadway for ...

Problems solved by technology

[0003] In actual use, when it is necessary to anchor the inner wall of the roadway, during the long-term anchoring process, due to the influence of internal changes in the rock and soil, the detachable anchor may be displaced and loose, which will affect the effect of anchoring. It is not easy to detect, and at the same time, when supporting the top of the roadway, because the heights of the roadways may be different, it is difficult to support the top of the roadway well, and further, it is inconvenient to support the roadway during use. Roof support components of the roadway are adjusted for movement
