Problems solved by technology

[0002] It is pointed out in related technologies that in shield tunneling construction, since the excavation interface pressure of the cutter head is much higher than atmospheric pressure, when the tool needs to be replaced, the operator basically enters the excavation interface higher than the atmospheric pressure to perform the tool change under pressure. operation, this method of tool change is risky and has a great impact on the health of the operator. At the same time, because the operator cannot work for a long time in the hyperbaric cabin, it takes a long time to change the tool

Abstract

The invention discloses a replacement device for shield cutters. The replacement device comprises a fixed part, a moving part and two gates, wherein the fixed part is provided with a containing cavity, two sides, in a first direction, of the containing cavity are open, the moving part is movably arranged in the containing cavity in the first direction, the shield cutters are suitable for arranging on one side, in the first direction, of the moving part, the two gates are arranged on the moving part and arranged on a second direction which is perpendicular to the first direction, the two gates can move opposite to each other in the second direction, the two gates are constructed to separate from each other during the moving part moves towards one side of the moving part in the first direction, and when the two gates moves close to each other after the moving part moves towards the other side of the moving part in the first direction, two sides of the containing cavity are separated. The replacement device for the shield cutters has the advantages that arrangement space of the replaceable shield cutters in a shield cutter disc is effectively saved, and stress-balance and whole strength of the shield cutter disc are guaranteed to a certain extent.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a shield tool changing device. Background technique [0002] It is pointed out in related technologies that in shield tunneling construction, since the excavation interface pressure of the cutter head is much higher than atmospheric pressure, when the tool needs to be replaced, the operator basically enters the excavation interface higher than the atmospheric pressure to perform the tool change under pressure. Operation, this method of tool change has high risks and has a great impact on the health of the operator. At the same time, because the operator cannot work for a long time in the hyperbaric cabin, the time required for tool change is long. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a shield cutter replaceme...
