A mine restoration and protection structure

Abstract

This invention relates to a mine restoration and protection structure, comprising a mine slope, a sliding track, a protective support plate hinged to one side of the sliding track, and an adjustable support mechanism that movably abuts against the protective support plate. The mechanism includes two self-locking sliders. The self-locking sliders drive a support rod to move horizontally. Gears mounted on the support rods drive an external gear ring to rotate, which in turn drives a disc to roll on the sliding track. A support connector with an M-shaped hinged structure is installed between the two discs. By controlling the rotation of the gears via a motor, the unfolding angle between the M-shaped hinged support rods A and B and the support crossbar can be adjusted, achieving multi-point dynamic support for the protective support plate, significantly improving impact resistance and stability. This solves the technical problem of insufficient support force in existing protective devices. Furthermore, the position of the self-locking sliders and the rotation of the motor can be adjusted according to different slope inclinations to optimize the support angle.

Description

Technical Field

[0001] This utility model relates to the field of mine restoration and protection equipment technology, and in particular to a mine restoration and protection structure. Background Technology

[0002] Mine restoration and protection structures refer to a series of engineering and technical means used to restore and protect the mounds at the edge of the mining area after mining has ended or the mining area has been abandoned, in order to prevent loose rocks and soil from rolling down to the roadside and hitting passersby.

[0003] Existing mine restoration and protection structures often use only a single protective device to protect against falling rocks at the edge of the mining area. This results in low support capacity, and if the falling rocks are large or the impact force is increased, the stability of the protective device may be affected, making it difficult to maintain effective protection. Furthermore, it is difficult to adjust the support angle according to different slope inclinations.

[0004] Therefore, it is essential to provide a mine restoration and protection structure to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a mine restoration and protection structure to overcome the shortcomings of the prior art. In this utility model, a sliding track is fixed to the bottom of the mine slope, a protective support plate is hinged to one side of the track, two self-locking sliders are inserted into the sliding track, and the position is locked by a positioning element. The motor is started, and the drive gear drives the outer gear ring to rotate, so that the disc rolls on the track. The disc pushes the support connecting rod A and the support connecting rod B to form an M-shaped hinged support connector that abuts against the protective support plate. The position of the self-locking slider and the direction of the motor are adjusted according to the slope inclination to optimize the support angle.

[0006] When gravel impacts the protective support plate, the impact force is transmitted to the support connector, which is hinged in an M-shape. The contact surface between the disc and the sliding track increases the force-bearing area. The positioning element of the self-locking slider prevents slippage. The motor can adjust the unfolding angle between the support link A, the support link B and the support crossbar in real time to ensure structural stability.

[0007] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0008] A mine restoration and protection structure is provided, including a mine slope, a sliding track installed at the bottom of the mine slope, a protective support plate hinged to one side of the sliding track, and an adjustable support mechanism movably abutting one side of the protective support plate, the adjustable support mechanism being movably installed on the sliding track.

[0009] Specifically, the adjustable support mechanism includes two self-locking sliders that are slidably engaged on a sliding rail. Each self-locking slider is equipped with a support rod, each support rod is equipped with a motor, each motor is axially driven by a gear, the gear is driven by an external gear ring, and a disc is axially mounted on the inner ring of the external gear ring.

[0010] Preferably, the outer ring of the disc movably abuts against the upper end face of the sliding track, one end of the disc is movably mounted to the end of the support rod via a bearing, and the other end of the disc is equipped with a support rod A. The bottom end of the support rod A is fixedly mounted on the end face of the disc, and the top end of the support rod A is hinged to a support rod B.

[0011] A support crossbar is hinged between the two support links B. The hinge between support link A and support link B is movable and abuts against the side of the protective support plate facing away from the mine slope. The two support links A, the two support links B and the support crossbar form an M-shaped support structure.

[0012] Two self-locking sliders are symmetrically installed relative to the vertical central axis of the sliding track. Each self-locking slider includes a rectangular slider body, which is slidably installed on the sliding track. A positioning element is installed between the sliding track and the rectangular slider body.

[0013] This invention uses a motor-driven gear to rotate an external gear ring, controlling the extension and retraction of an M-shaped hinged support connector to achieve dynamic support for the protective support plate, significantly improving its impact resistance. The self-locking slider slides along the sliding track to adjust the support position, and the disc abuts against the sliding track to distribute pressure, adapting to different slope shapes. The M-shaped hinged support connector provides multi-point support, and together with the self-locking slider positioning element, it prevents structural displacement caused by gravel impact. The motor controls the support angle adjustment, eliminating the need for manual disassembly and greatly improving maintenance efficiency. Attached Figure Description
