Problems solved by technology

The drive mechanism of the cutter head is the heart of the shield tunneling machine. The slewing support bearing is like the ventricle and atrium of the heart. If it is damaged, the heart will stop and the shield machine will not be able to continue to work.
The slewing support bearing of the cutter head drive mechanism of the conventional shield machine cannot be disassembled, replaced and repaired during tunnel construction and excavation. Once a fatal failure occurs, the shield machine will be paralyzed and the tunnel excavation will be at a standstill.
If the failure occurs when the machine cannot be excavated when it crosses a large river or the underground area of ​​an important land building, the shield tunnel will face serious consequences of diversion or scrapping

Abstract

The invention relates to a detachable slewing bearing fixing device of a shield heading machine cutter head driving mechanism. The detachable slewing bearing fixing device comprises a slewing bearing, a power box base, a power box cover, a force transmission ring, a center bin, connecting bolts, a cutter head driving mechanism seal assembly and the cutter head driving mechanism. A static inner ring of the slewing bearing is fixedly connected with the power box cover through the corresponding bolt, and the power box cover is fixed to the power box base through the corresponding bolt. The center bin is fixedly connected with the power box cover through the corresponding bolt. In the construction process, when a critical failure occurs on the slewing bearing of the shield heading machine cutter head driving mechanism, the slewing bearing is detached and cleared of the failure to be maintained or updated, in this way, equipment normally operates and effectively works, and then smooth completion of engineering is guaranteed.

Description

technical field [0001] The invention relates to a shield tunneling equipment, in particular to a detachable structure of a rotary support bearing fixing device of a cutter head driving mechanism of a shield tunneling machine. Background technique [0002] The shield boring machine is the key equipment for the construction of the shield tunneling project. It is widely used in large-diameter pipeline projects such as urban rail subway tunnels, nuclear power plant junction drainage tunnels, and urban sewage drainage tunnels. The cutter head drive mechanism is the heart of the shield tunneling machine, and the slewing support bearing is like the ventricle and atrium of the heart. If it is damaged, the heart will stop and the shield machine will not be able to continue to work. The slewing support bearing of the cutter head drive mechanism of the conventional shield machine cannot be disassembled, replaced and repaired during tunnel construction and excavation. Once a fatal fail...
