Shield segment splicing machine with six-freedom degree

Abstract

The invention relates to a shield construction tube assembler with six freedoms, which comprises a rotational disc, a driving device, two suspending beams, two translation cylinders, two guide sheathes, two guide inner sheathes, two lifting cylinders, a lifting beam, a tube clamper, a tube weight, a rotational platform, a central ball joint bearing, a tube incline cylinder, a tube rotational cylinder, a fixed disc and a rolling wheel. The invention has six freedoms to meet the demand of assemble different spatial positions; and a middle beam and a tube clamper, etc, are arranged between two suspending beams to improve the system stability.

Description

technical field [0001] The invention relates to a tunnel engineering construction machine, in particular to a shield segment assembling machine. Background technique [0002] The segment assembly machine is one of the important key components in the tunnel boring machine for tunnel construction. After the shield machine is excavated forward, the segments must be assembled into the tunnel lining immediately at the rear. The work of assembling the segments is completed by the assembly machine. The function of the segment assembly machine directly affects the quality of the segment assembly and the tunnel lining. construction efficiency. [0003] After document retrieval, it was found that the Chinese patent "Lining Assembly Machine with Pressure Type Fully Sealed Mailbox" (publication date: October 15, 2003) with application number 03116809.4 discloses a tunnel segment assembly machine, and its structural diagram can be found in attached figure 1 and 2 . The segment assem...

Problems solved by technology

The movement of the mechanism has four degrees of freedom. However, in actual construction, not every segment can be assembled in a regular ideal position, and it is likely to need to have a certain plane with the tunnel space, such as the cross-section of the tunnel. A small angle, obviously, the above-mentioned assembly machine with only four degrees of freedom cannot meet the requirements of segment construction

[0005] In addition, the left and right cantilever beams 503 of the segment assembly machine are only connected by the lifting beam 506, so the overall rigidity of the equipment is relatively poor, and the working load will destroy the parallelism of the axes of the left and right second lifting cylinders 505, making the second lifting cylinder 505 The lifting and lowering movement is not synchronous, which will cause serious consequences of segment assembly misalignment

[0006] Furthermore, the segment tongs 510 of the segment assembly machine are directly arranged on the translation cylinder 509, and all the weight of the segment is borne by the cylinder body of the translation cylinder 509, which will affect the overall stability of the translation cylinder 509 and the translational movement. Stationarity adversely affects
