Roadway supporting equipment

Abstract

The invention relates to the technical field of roadway supporting and discloses roadway supporting equipment which comprises a mounting arm and a supporting shed frame, wherein the supporting shed frame comprises a top beam, two shoulder beams, two supporting columns and two upper connecting boots, the top beam is suitable for abutting against the top of a roadway; first ends of the shoulder beams are rotatably connected with one end of the top beam, and the two shoulder beams are connected with two ends of the top beam respectively; the supporting columns are rotatably connected with second ends of the shoulder beams, the two supporting columns are connected with the two shoulder beams respectively, and the supporting columns are telescopic; the upper connecting boots are rotatably connected with the second ends of the shoulder beams, the upper connecting boots are located on the outer side of the shoulder beams and the outer side of the supporting columns, and the upper connecting boots are suitable for abutting against the side wall of the roadway; the mounting arm is suitable for being mounted on an engineering vehicle and detachably connected with the supporting shed frame. The roadway supporting equipment provided by the invention has advantages of light weight, small size and easiness in carrying, dismounting and mounting, automation and unmanned operation during working face tunneling can be realized, the risk that workers suffer from occupational diseases is reduced, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to roadway support equipment. Background technique [0002] Existing mechanized excavation of rectangular roadways generally adopts the excavation method of supporting while digging, and the working face of the roadway requires a large number of workers to work together at the same time, and these workers are in extremely harsh working environments. According to statistics from the National Health Commission, by the end of 2018, the cumulative number of reported occupational cases in the country exceeded 970,000, ranking first in the world, most of which were concentrated among mine workers. In mines, especially the mine excavation working face, the environment is harsh. Dust, heat damage, noise and toxic and harmful gases constitute the "four evils", which seriously threaten the health of workers and lead to the occurrence of various occupational diseases, such as pneumocon...

AI Technical Summary

Problems solved by technology

[0003] In addition, during the excavation construction process of the existing rectangular roadway, the support work of the roadway is the most important factor restricting its automation and unmanned operation.

At present, it is difficult to automate the anchoring work of the ordinary bolt support method. Although some manufacturers' equipment is being tested, the failure rate is high, and it has not yet been widely used.
