Description

TECHNICAL FIELD

[0001] The present application relates to the field of tunnel construction, in particular to a working device vehicle for existing line tunnel construction and a construction method thereof. BACKGROUND

[0002] The existing line tunnel construction refers to the construction of new or reconstruction on the basis of the built line. The tunnel chiseling construction is to chisel a series of pits on the tunnel inner wall surface, so that the construction surfaces of two construction stages are tightly bonded.

[0003] At present, the tunnel chiseling equipment mainly includes airborne chiseling machines and tunnel special chiseling machines and other large mechanized operation tools. When the above tools work, the line close to the tunnel inner wall surface, such as the contact line, the side wall public network line and the lighting line, needs to be effectively avoided. Further, in the subsequent construction process, the existing line needs to be moved away from the tunnel inner wall surface, and then the area shielded by the existing line is separately chiseled. However, due to the large size of the above equipment and the single operation line, it is not convenient to chisel in the narrow area; and the workload is increased, the construction efficiency is reduced, and it is difficult to cover the full-face construction of the tunnel. SUMMARY

[0013] By adopting the above technical scheme, all the functional modules on the auxiliary frame are reloaded onto the corresponding standard flatbed transport vehicle according to different railway lines. When the tunnel full-face is chiseled, the line in the tunnel is pulled along the tunnel section radially inward to move away from the inner wall of the tunnel. Further, the first mechanical arm telescopic part and the second mechanical arm telescopic part are driven to rotate, the slide rail mechanism is adjusted in angle, the slide rail mechanism is close to the inner wall of the tunnel and crosses the line, and then the chiseling mechanism is started to begin chiseling. When chiseling, the arc-shaped slide rail moves relative to the slide rail bracket, and then the position of the chiseling mechanism is changed to chisel. After the above work station chiseling is completed, the position of the mechanical arm telescopic part is changed, so that the arc-shaped slide rail moves along the same section to the next work station to start chiseling, until the full-face chiseling work is completed. The arc-shaped slide rail of the above scheme can easily cross the line, without affecting or damaging the existing line, and then all the inner wall chiseling in the same section is efficiently processed by moving the position of the arc-shaped slide rail at one time.

[0034] On the other hand

[0035] The application also provides a construction method adopting the technical scheme as follows:

[0036] Preferably, the existing line tunnel chiseling working device vehicle is adopted, and the construction method includes the following two cases:

[0037] When the tunnel inner existing pipeline is attached to the tunnel inner wall:

[0038] The working basket carries the operator, the operator pulls the tunnel inner existing pipeline away from the inner wall,

[0039] The horizontal sliding track and / or the rotating platform are used to adjust the mechanical arm luffing and telescoping mechanism, and the mechanical arm luffing and telescoping mechanism is used to telescopically extend and luff, so that the sliding rail mechanism crosses the line and approaches the inner wall of the tunnel, and then the chiseling mechanism is driven to chisel.

[0040] When there is a distance between the existing pipeline in the tunnel and the inner wall of the tunnel:

[0041] The horizontal sliding track and / or the rotating platform are used to adjust the mechanical arm luffing and telescoping mechanism, and the mechanical arm luffing and telescoping mechanism is used to telescopically extend and luff, so that the sliding rail mechanism crosses the line and approaches the inner wall of the tunnel, and then the chiseling mechanism is driven to chisel.

[0042] It also includes a longitudinal tunnel chiseling mode:

[0044] By adopting the above technical scheme, the tunnel full section is chiseled, which has high working efficiency, can cross and avoid the line in the tunnel to complete the chiseling work, and will not cause damage to the line. The horizontal sliding track drives the whole mechanical arm luffing and telescoping mechanism to slide along the longitudinal direction of the tunnel and then move to the next working position, and the mechanical arm luffing and telescoping mechanism and the chiseling mechanism are adjusted again to approach the tunnel wall for chiseling construction, which meets the requirement of single parking covering a large longitudinal working range.

[0046] The horizontal sliding track and / or the rotating platform are used to adjust the mechanical arm luffing and telescoping mechanism, and the mechanical arm luffing and telescoping mechanism is used to telescopically extend and luff, so that the sliding rail mechanism approaches the arch foot to complete the line riding, and then the reciprocating movement assembly drives the chiseling mechanism to chisel against the inner wall.

[0047] By adopting the above technical scheme, when the wall-attached line at the arch foot is crossed, the chiseling mechanism cannot chisel at the arch foot, the sliding rail mechanism is used to avoid the line by riding the line, and then the reciprocating movement assembly drives the chiseling mechanism to move to chisel against the inner wall.

[0048] In summary, the present application has the following at least one beneficial technical effect:

[0049] 1. For different railway lines, all functional modules on the auxiliary frame are reloaded onto the corresponding standard flatbed transport vehicle. The arc-shaped sliding rail that can adapt to the curvature of the tunnel section can easily cross the line without affecting or damaging the existing line, and then all the inner walls in the same section are efficiently processed by moving the position of the arc-shaped sliding rail once.

[0050] 2. When moving to the unchiseled area after a part of the chiseled section is completed, due to the need to maintain a certain distance between the arc-shaped sliding rail and the inner wall of the tunnel, a part of the arc-shaped sliding rail is suspended on the pit of the chiseled area when the chiseling mechanism is working. By embedding the leveling block into the pit and abutting against the inner wall, the chiseling mechanism can maintain the stability of the arc-shaped sliding rail when vibrating, and avoid the arc-shaped sliding rail from shaking and colliding with the inner wall as much as possible.
