Description

Technical Field

[0001] The invention belongs to the field of double-shield TBM tunnel construction, and in particular relates to a segment unloading transporter for a double-shield TBM tunnel. Background Art

[0002] With the rapid development of tunnel and underground space engineering in my country, more and more tunnels are being planned and constructed. As the fastest and most efficient machine in various types of TBM tunnel construction, the double shield TBM is attracting more and more attention and use. Due to the small construction space of the tunnel underground space, the traditional segment assembly process is to repeatedly use a battery trolley to transport a ring of segments to the rear supporting trolley position from the entrance shaft, and then manually screw the segment lifting screws on the segment, and use the segment feeder to lift the segment back and forth to the pads near the segment assembly machine, and then adjust the position and posture of the segment assembly machine to assemble the segment. Considering safety issues, the lifting speed set by the segment feeder is generally very slow, and the lifting operation still relies heavily on manual cooperation, which seriously affects the assembly efficiency. In addition, it is very easy to damage the segments during multiple transportation processes, which seriously affects the quality of the segments after assembly. Therefore, it is very necessary to design this segment unloading and transporting device for double shield TBM tunnels, which has strong practical significance. Summary of the invention

[0003] The technical background of the present invention is to solve the problems of segment unloading, position adjustment, transportation and storage as well as safety during segment assembly in double-shield TBM tunnel construction, and to comprehensively improve the efficiency and safety of tunnel construction.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a segment unloading transporter is designed, which can lift the segments transported by the segment trolley from the segment trolley by adjusting the height of the lifting cylinder, and then can walk along the guide rails of the trolley behind the TBM to replace the traditional segment feeding machine for lifting the segments. In addition, a ring of segments can also be temporarily stored to relieve the occupancy of the segment transport trolley.

[0005] The main components of the unloading conveyor include: a combined frame, a right vertical lifting cylinder, a guide stabilizing beam, a right horizontal driving cylinder, a left horizontal driving cylinder, a rubber wedge block, a control component, a vertical moving guide rail, a left vertical lifting cylinder, and a slideway card plate.

[0006] The specific method of the segment unloading conveyor to perform vertical lifting and lowering is as follows:

[0007] The right vertical lifting cylinder and the left vertical lifting cylinder are driven, preferably by hydraulic drive, and then the pipe segments stored in the rubber wedge blocks are driven via the vertical moving guide rails, thereby unloading the pipe segments and adjusting the vertical position of the pipe segments through vertical posture movements.

[0008] The specific methods of the horizontal movement and horizontal fine-tuning of the segment unloading conveyor are as follows: the control component controls and drives the right driving cylinder and the left driving cylinder, and the driving method is preferably hydraulic drive, and then the horizontal movement is achieved by driving the slide plate in the double shield TBM guide rail groove.

[0009] Technical effects of the present invention:

[0010] (1) The unloading transporter of the present invention can quickly unload the segments from the segment transport trolley and quickly transport them to the segment assembly machine along the guide rail slide provided on the rear supporting trolley of the TBM for segment assembly. At the same time, it has the functions of adjusting the segment position height and storing the segments to make up for the problem of insufficient space in the tunnel construction hole.

[0011] (2) The present invention has a simple structure, is easy to operate, safe and reliable, replaces the function of the segment feeder, reduces manual involvement, improves the overall efficiency of tunnel construction, solves the damage and related safety issues that may be caused during the multiple transportation of segments, and improves the overall quality of the tunnel after forming.
