Emergency supporting device for coal mine collapse and convenient to quickly unfold

Abstract

The invention discloses an emergency supporting device for a coal mine collapse which isand convenient to quickly unfold. The device comprises a substrate, an electric push rod, a supporting rod, anabutting butt-joint rod and a pressure sensor; the electric push rod is installed on the inner side of the substrate in an embedded mode; a fixed rack is installed on a bolt of at an output end of theelectric push rod through bolts ; an installation piston is fixedly connected with the upper end of the fixed rack; a gas collecting cavity is formed in the upper end of the inner side of the substrate; the gas collecting cavity is connected with the installation piston; a gas transportation passage is installed on the outer side of the gas collecting cavity in an embedded mode; and an installation airbag is fixedly connected with the outer end of the gas transportation passage. According to the emergency supporting device for the coal mine collapse which isand convenient to quickly unfold,the pressure sensor at the upper end of the device receives a pressure signal of collapse, the electric push rod is stably driven through a preset program, and thereby the supporting rod is stably driven by an engaging structure between gears to be unfolded outwardly while at the same time the abutting butt-joint rod which abuts against the upper end of the supporting rod is unfolded upwardly to cooperate with the connecting rod to stably and quickly realize protection operation.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a convenient and quick-deployable emergency support device for coal mine landslides. Background technique [0002] A coal mine is a reasonable space excavated by human beings when excavating geological layers rich in coal, usually including roadways, shafts and mining faces, etc. In the mining face, due to changes in geological structures, wrong support selection, and construction personnel's faults , operating machinery errors and other reasons may easily cause the partial fall of the roof of the mining face, which will cause personal injury to the operator. Therefore, it is necessary to adapt the corresponding emergency support device in the coal mine environment to prevent accidents. However, the existing coal mine There are also certain defects in emergency support devices for landslides, such as: [0003] 1. The existing emergency support devices for coal mine landslides...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a convenient and quick-deployed emergency support device for coal mine landslides, so as to solve the problem in the above-mentioned background technology that in the event of a sudden emergency, the working state that can not be conveniently and stably realized to be quickly deployed is still a problem. The user needs to move to the corresponding position to perform manual and cumbersome operation steps, which brings inconvenience to the emergency rescue work. At the same time, the safety of the operator cannot be effectively guaranteed, and there are certain defects in the support stability, which leads to excessive pressure. Under such circumstances, it is impossible to obtain timely escape time for users, and at the same time, its support range is small, and it is impossible to stably cover some of the broken stones.
