Supporting device for coal mine safety engineering protection

Abstract

The invention relates to the technical field of coal mine safety engineering, and discloses a supporting device for coal mine safety engineering protection. The supporting device comprises a first supporting fixed cone, and a supporting column is fixedly mounted at the top of the first supporting fixed cone. According to the supporting device for coal mine safety engineering protection, broken stones at the top are shielded through baffles and are prevented from hurting pedestrians, the baffles bear force from the broken stones, force is transmitted to a triangular bearing frame through bearing springs, a supporting plate is still in contact with the top of a channel due to tension effect of extension springs, and the triangular bearing frame descends; under the combined action of an air spring column, a pressure spring and a buffer spring, downward force is buffered, and a second magnet and a first magnet repel each other, so that the action of the force is further relieved; and therefore, broken stones above a coal mine channel are prevented from falling down and injuring workers, the situation that the service life of the baffles is shortened due to the fact that the baffles are damaged by the broken stones and coal mining work is not facilitated is avoided, and use by a user is facilitated.

Description

technical field [0001] The invention relates to the technical field of coal mine safety engineering, in particular to a support device for protection of coal mine safety engineering. Background technique [0002] The areas where human beings mine coal resources in coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to dig underground roadways to mine coal. This is an underground coal mine. When the coal seam is far from the surface When the distance is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in my country belong to underground coal mines. The scope of coal mines includes a large area above ground, underground and related facilities. Reasonable space excavated when there are geological layers of coal, usually including roadways, shafts and mining faces, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a support device for coal mine safety engineering protection, which has the advantages of good protection effect, etc., and solves the problem that the support and fixation of the existing support device for coal mine protection are not reliable and cannot effectively prevent the upper part from being broken. The fall of stones hurts the staff, and it cannot slow down the damage to itself caused by the crushed stones, resulting in a decrease in its own service life, which is not conducive to the development of coal mining work.
