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.
