Tunnel wall arc roof digging and leveling machine

Abstract

The invention discloses a tunnel wall arc roof excavating and leveling machine, and mainly relates to the technical field of tunnel wall excavation and leveling. The tunnel wall arc roof excavating and leveling machine includes a vehicle body, a driving device assembly, a main shaft, a hinged rod and a plurality of arc-shaped chisel frames; a servo oil cylinder is arranged on the main shaft; a sliding seat is slidably connected to the main shaft; a telescopic rod is arranged at the top of the main shaft; a connecting frame is arranged at the top of the telescopic rod; a center seat is arrangedat the top of the connecting frame, and the multiple arc-shaped chisel frames are hinged to the periphery of the center seat; the middle sections of the inner surface of the arc-shaped chisel framesare hinged to one end of the hinged rod, and the other end of the hinged rod is hinged to the sliding seat; thick chisel cloth is laid at the top of the center seat and at the tops of the arc-shaped chisel frames in a tight supporting mode, and chisel teeth are fixed to the thick chisel cloth; and vibration motors are arranged in the inner surfaces of the arc-shaped chisel frames and the inner surface of the center seat. The tunnel wall arc roof excavating and leveling machine has the beneficial effects that the tunnel arc-shaped roof wall can be effectively excavated and leveled, and the relative flatness of the tunnel arc-shaped roof wall is ensured, so that the subsequent installation and erection of the supporting measures of supporting bolts, supporting frame beams and the like are facilitated.

Description

technical field [0001] The invention relates to the technical field of roadway wall leveling, in particular to a roadway wall arc top leveling machine. Background technique [0002] In the coal mine roadway excavation process, in order to ensure the installation of subsequent support beams, the roadway wall needs to be excavated to ensure that the roadway wall is relatively flat, so as to facilitate the installation and erection of support measures such as subsequent support bolts and support frame beams. . [0003] The sidewalls on both sides of the roadway are close to the ground of the roadway, so it is easy to dig and level, but it is more difficult to level the top wall of the arc top of the roadway. At present, there is no mechanical energy for high-efficiency digging at the top of the roadway. Contents of the invention [0004] The object of the present invention is to provide a roadway wall arc roof leveling machine, which can efficiently level the roadway arc-sha...

Problems solved by technology

[0003] The sidewalls on both sides of the roadway are close to the roadway ground, so it is easy to dig and level, but it is even more difficult to level the top wall of the arc top of the roadway. At present, there is no mechanical energy for high-efficiency digging at the top of the roadway
