Problems solved by technology

[0003] At present, in the shield construction of existing underground tunnel projects at home and abroad, more and more projects adopt the method of dismantling the machine in the hole. There is no blind hole in the front of the shield machine during dismantling, which is not convenient for the main drive to be disassembled. The previous cutting method will cause a lot of waste

Abstract

The invention belongs to the technical field of tunneling construction of shield tunneling machines for tunnels, particularly relates to a device for in-tunnel demounting of a screw conveyer of the shield tunneling machine and mainly provides a novel method and a novel device for demounting of a master drive of the shield tunneling machine. In order to realize in-tunnel mounting and demounting of the master drive of the shield tunneling machine and guarantee safety and effectiveness in in-tunnel assembly, maintenance and disassembly of the master drive of the shield tunneling machine, a device for in-tunnel demounting of the master drive of the shield tunneling machine is provided and comprises a shield, the master drive, the screw conveyer and a beam shaped as a Chinese character 'mi' meaning rice, the master drive is arranged at the front end of the shield, and the beam is arranged in the shield. A plurality of lifting lugs are welded to the beam, a lifting base point is arranged above the tail of the screw conveyer, and the lifting lugs on the beam and lifting lugs on the screw conveyer are connected. The method and the device for in-tunnel demounting of the master drive of the shield tunneling machine have the advantages that in-tunnel mounting and demounting of the master drive are realized effectively, in-tunnel mounting, demounting and maintenance of the master drive are facilitated, construction efficiency is improved, and hoisting and mounting of large structural parts can be realized safely.

Description

technical field [0001] The invention belongs to the technical field of excavation and construction of a tunnel shield machine, and in particular relates to a disassembly device and method for a main driving hole of a shield machine. Background technique [0002] my country is in a period of rapid economic and technological development. Shield machines are special equipment for tunnel engineering. Their design and manufacturing capabilities reflect the comprehensive level of a country's equipment manufacturing industry. Therefore, it is important for the design and manufacture of shield machines and related construction technology research. the value of. [0003] At present, in the shield construction of existing underground tunnel projects at home and abroad, more and more projects adopt the method of dismantling the machine in the hole. There is no blind hole in the front of the shield machine during dismantling, which is not convenient for the main drive to be disassembled....
