Description

Technical Field

[0001] The present application relates to the technical field of shield machine disassembly and assembly, and in particular to a large-diameter main drive disassembly tooling in a tunnel. Background Art

[0002] The large-diameter shield machine itself is large in size and needs to be dismantled after being taken out of the tunnel one by one and then hoisted separately. In particular, the main drive weight of the large-diameter machine reaches 250 tons, which makes it more difficult to take the large-diameter shield machine out of the tunnel and dismantle it as a whole.

[0003] For the in-hole disassembly of the main drive of a large shield machine, since the disassembly process is carried out inside the shield machine shell, the structural dimension of the shell is a circular thickness of 50mm, and the stress state cannot meet the conventional disassembly requirements, so the disassembly needs to be carried out with the help of other heavy equipment. Carrying out other heavy equipment on site will extend the construction period, or directly using a lifting device to disassemble and assemble the main drive on site is inconvenient for disassembly, assembly and turning over of the main drive, and is also prone to safety accidents.
