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 device and method for replacing a shield cutter. The device comprises a fixing part, a retainer, a movable part, two gates and a gate switching oil cylinder. The two sides ofa containing cavity of the fixing part are open in the first direction. The retainer is connected to one side of the fixing part, and the other side of the retainer is connected with an oil cylinderlimiter. The movable part is movably arranged in the containing cavity and the retainer in the first direction. The first end of the dismounting and mounting oil cylinder is connected to the other side of the movable part, and an oil cylinder lug plate connected with the second end of the dismounting and mounting oil cylinder is arranged at the position of the oil cylinder limiter. The two gates are arranged on the fixing part and can oppositely move in the second direction vertical to the first direction. The gate switching oil cylinder is in drive connection to the two gates in order to control the two gates to be oppositely closed or opened back to back. As the two gates are arranged on the fixing part, the arrangement space, in which the cutter can be replaced, in a shield cutterhead is effectively saved, and load carrying balance and overall strength of the shield cutterhead are guaranteed to a certain degree.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a shield cutter replacement device and replacement method. 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] In order to overcome the defects in the prior art, the present invention provides a shield tool replacement device and a replacement method, which can save the ...
