Transverse moving device for launch shaft heading machine

Abstract

The invention discloses a transverse moving device for a launch shaft heading machine. The transverse moving device comprises a vertical shaft; the upper end of the vertical shaft is provided with a vertical shaft opening; the bottom of the vertical shaft is provided with a supporting frame; the upper end of the supporting frame is provided with a transverse moving sliding track; and the upper end of the transverse moving sliding track is provided with a sliding plate, and the sliding plate is slidably connected with the transverse moving sliding track. A launch frame platform is arranged at the upper end of the sliding plate; the upper end of the launch frame platform is provided with a supporting track; a shield machine is arranged at the upper end of the supporting track; one side of the launch frame platform is fixedly connected with a steel wire rope; the end, away from the launch frame platform, of the steel wire rope is provided with a traction device; and a chain block is arranged on the steel wire rope. A shield machine main body is directly placed on the launch frame platform, under the state, the shield machine main body on the track can be transversely moved, meanwhile, after movement, the transverse moving device can conduct launching under the same state, the working efficiency is improved, and the working progress is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a lateral movement device used for a tunneling machine for an initiation shaft. Background technique [0002] In the process of shield tunneling construction, there are many cases of construction under the road. Generally speaking, when the body of the shield machine is going down the well, the ideal way is to stop the traffic on the road, and then lower the body to the starting position under the road. But on a road with a lot of traffic, it is basically impossible to stop the traffic on the road. [0003] Therefore, at this time, the general method is to use a part of the road to excavate the wellhead, and then move the body laterally to the inside after the body is lowered into the well at the opening. [0004] In the past, there are two types of horizontally moving devices for shield machines that are widely known. One method is to use a jack to move the platform ...

Problems solved by technology

However, the first method pushes a 50-ton to 200-ton shield machine in an unstable direction, which is extremely difficult to operate and is accompanied by a certain degree of danger

As for the second method, because of the use of rollers, although the lateral movement can be easily carried out, it is necessary to repeatedly bring the rollers to the front alternately, and the rollers and iron plates must be removed when the shield machine is starting.
