Abstract

The invention provides a disassembling and transporting method of a main drive of a shield tunneling machine in a tunnel. The method comprises the steps that other structures except the main drive, ashell and a soil cabin partition plate are disassembled; the soil cabin partition plate is cut to form a notch penetrating through the position between a main drive reduction box and the shell, and the notch is located below the main drive reduction box; a rail to the outside of the tunnel is laid in the notch; a transporting cart which is provided with a plurality of supporting pieces used for supporting the main drive reduction box is supplied; the transporting cart is arranged on the rail and kept below the main drive reduction box, and the supporting pieces make contact with the main drivereduction box; the soil cabin partition plate is annularly cut along the outer wall of the main drive reduction box until the main drive reduction box is completely separated from the soil cabin partition plate, and the supporting pieces completely support the main drive reduction box; the transporting cart is kept on the rail and dragged along the rail, and thus the main drive is transported tothe outside of the tunnel to be disassembled. The main drive is conveyed to the outside of the tunnel to be disassembled, so that the problem that the main drive is not easy to disassemble due to narrow space in a shield tunneling machine shell is solved.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a method for dismantling and transporting the main drive of a shield machine in a tunnel. Background technique [0002] The shield machine has been widely used in the process of subway tunnel excavation. After the shield machine completes the excavation task, it will generally be disassembled and hoisted out in the preset hoisting well. However, there is also a special situation, that is, the shield machine Shelling reception means recovering all mechanical parts except the shell of the shield machine. [0003] As an important component of the shield machine, the main bearing needs to be recycled. At present, the commonly used method when recovering the main bearing is to eject the main bearing in the tunnel, lay it flat and then transport it out of the tunnel. However, due to the narrow space in the shell of the shield machine, the use of disassembly tools is limited. [000...
