Supporting device for roadway support

Abstract

The invention relates to the field of mining auxiliary devices, in particular to a supporting device for roadway support. The supporting device comprises a first support, a second support, a supporting structure, a shielding structure, a limiting structure, a control structure and a fixing structure. Through the arrangement of the fixing structure, the first support and the second support can be conveniently fixed inside ground rock soil inside a roadway; through the arrangement of the shielding structure, fine falling stones and falling ash falling from the position right above the roadway can be blocked, and water drops falling from the position above the roadway can be received; through the arrangement of the limiting structure, the supporting device can be kept stable after being mounted and is not prone to shake; through the arrangement of the fixing structure, the first support and the second support can be conveniently fixed inside ground rock soil inside the roadway so that thewhole supporting device can be stably fixed inside the roadway; and through the arrangement of the control structure, the fixing structure can be matched, so that the fixing structure is more easilyfixed on the ground inside the roadway.

Description

technical field [0001] The invention relates to the field of mining auxiliary devices, in particular to a supporting device for roadway support. Background technique [0002] Roadway refers to a roughly horizontal tunnel excavated on the ground or underground when mining or visiting a mine. Half of it is used for transportation or drainage, and the underground is also used for ventilation. Since mining needs to be carried out underground, it is necessary to open Digging a roadway connects the underground with the ground through the roadway. Miners can enter the roadway from the surface and then enter the ground. The ore mined in the roadway and underground water are transported to the surface through the roadway. Therefore, when excavating the roadway, it is necessary to set up support devices in the roadway to support the rock and soil on the inner wall of the roadway. [0003] Due to the narrow space in the roadway, the size of the support device used for roadway support ...

AI Technical Summary

Problems solved by technology

[0003] Due to the narrow space in the roadway, the size of the support device used for roadway support needs to fit the roadway, that is, the size of the support device and the passageway of the roadway are almost the same, so the support device is not convenient to be directly transported from the ground to the roadway. Usually, it needs to be completely dismantled first, and the parts are sent to the roadway for reinstallation. The whole installation process is relatively cumbersome, and the existing roadway support device mainly supports the rock and soil in the roadway, and the roadway is in the support device. Under the support, landslides are not easy to occur, but there will still be small falling rocks, ash and water droplets, which will affect the movement of miners and mine cars in the roadway
