Mine tunnel supporting device

Abstract

The invention discloses a mine tunnel supporting device, comprising an arched frame. A protective net is movably connected in the arched frame. The arched frame includes first modules, the top of eachfirst module is movably connected with a second module, the tops of the second modules are movably connected with a third module, and the top of the third module is movably connected with roof protection devices. Each roof protection device includes a threaded rod, a hexagonal slot is arranged in the bottom of the threaded rod, and a lower roof is arranged on the top of the threaded rod. A firstgroove is arranged in the middle of the bottom of each lower roof. Second grooves are arranged on the front and rear sides of the bottom of the lower roof, and the lower end of each second groove is fixedly connected with a stud. A first through hole is arranged in the middle of each stud, and the lower end of each stud is movably connected with a first screw. The protective net includes steel wires, a first connecting block is arranged at each of the T-shaped junctions of the steel wires, and a second connecting block is arranged at each of the cross junctions of the steel wires. The mine tunnel supporting device is convenient to assemble and disassemble during use without need for secondary processing, is highly compatible with the tunnel shape, and has a function of simple pipeline laying in jumper slots.

Description

technical field [0001] The invention relates to the field of tunnel support, in particular to a mine tunnel support device. Background technique [0002] With the development of the coal industry, mine support technology and support equipment have also been greatly developed. Mine support equipment mainly refers to the support equipment designed and manufactured to maintain the safety of the roof of the working face during the underground mining process. working environment. Mine support is directly related to the safety, efficiency, consumption (especially the bulk consumption of wood and steel), environmental protection and industrial hygiene, mining cost and mechanization level of coal mining operations. Mine support equipment accounts for a large proportion of underground mining production costs.

AI Technical Summary

Problems solved by technology

[0003] Although the existing support equipment has a basic form, it is not compatible with the actual environment of the mine; during installation, it needs to be rectified twice according to the actual shape of the mine, which not only delays the construction period, but also increases the support cost; another point The existing installation and disassembly are extremely inconvenient, the support frame is basically welded when installed, and cut when disassembled, and the combination is not strong; further, the existing support frame only plays the role of support , poor compatibility with ventilation pipes and cables used in mining; other equipment needs to be added to the support frame when arranging pipes and cables
