Arc-shaped track wall-sawing machine

Abstract

The invention provides an arc-shaped track wall-sawing machine. Through machining a track into a keel shape, the track is curved to a radian attached to an arc-shaped track bed, the supporting intensity of the track does not changed, and the track is reusable. The track bed is segmented and convenient to install and disassemble. A wall-sawing machine head can be disassembled and installed rapidly,a suitable gap is formed between the outer cambered surface of an arc-shaped track and the inner wall of a tunnel, and the arc-shaped track and a trolley moving in the tunnel is convenient. A motor in-out oil pipe is vertically arranged in the section direction of the arc-shaped track, cutting of the wall-sawing machine does not be affected, and the thickness of the wall-sawing machine head is compressed to enable the wall-sawing machine head to have the maximum passing ability. A meshing center of a feeding gear and a rack is on the center section of left and right wheels to avoid the feeding gear breaking away from the rack or getting stuck caused by changing of the track radian. The arrangement of an elastic adjustment device enables rollers to mesh with multi-radian arc-shaped tracks,the feeding gear on the center of the two rollers is ensured, and the problem of shield protection is further solved.

Description

technical field [0001] The invention relates to the field of track technology, in particular to an arc track wall sawing machine. Background technique [0002] During the long-term use of road tunnels, railway tunnels, and high-speed rail tunnels, some tunnel repairs or upgrades require stripping of the original tunnel walls. The conventional method is to use a gun to break or use a wall saw to install a one-meter-long straight track. For segmental cutting, there is also the way of cutting multi-arc arc track with wall saw machine. The multi-arc arc track cutting is static cutting, which will not damage the buildings that need to be preserved. It can cut reinforced concrete and steel structures. When cutting tunnels , can fit the tunnel arc and perform multi-arc cutting according to the tunnel arc, but the multi-arc arc track cutting in the prior art has the following problems: the distance between the arc track and the inner wall of the tunnel is about 10cm, and when the tr...

[0002] During the long-term use of road tunnels, railway tunnels, and high-speed rail tunnels, some tunnel repairs or upgrades require stripping of the original tunnel walls. The conventional method is to use a gun to break or use a wall saw to install a one-meter-long straight track. For segmental cutting, there is also the way of cutting multi-arc arc track with wall saw machine. The multi-arc arc track cutting is static cutting, which will not damage the buildings that need to be preserved. It can cut reinforced concrete and steel structures. When cutting tunnels , can fit the tunnel arc and perform multi-arc cutting according to the tunnel arc, but the multi-arc arc track cutting in the prior art has the following problems: the distance between the arc track and the inner wall of the tunnel is about 10cm, and when the track moves, it will be caused by the unevenness of the inner wall of the tunnel. The arc track cannot be moved through as a whole, and needs to be disassembled and moved in sections; every time the arc track moves a station, it needs to be re-clamped to fix the arc track to the inner wall of the tunnel, resulting in a much lower efficiency than that of installing a mobile trolley
