A device and working method for quickly changing the cutter head of a pipe jacking machine

Abstract

The invention relates to the technical field of pipe jacking machine cutterheads, in particular to a device for quickly replacing the cutter head of a pipe jacking machine and its working method. The accommodating hole for accommodating the cutter head, the tool box can be installed at the rear, the inside of the tool box accommodates the tool head box, the inner side of the tool box has a chute that can limit the cutter head box, and the surface of the chute is oppositely equipped with a pop-up seal The button and the detection arm switch respectively control the lifter of the sealing plate and the detection arm. The cutter head box has a cutter hole to communicate with the receiving hole of the front plate, so that the cutter head installed in the cutter head box protrudes from the front plate. , the rear is equipped with a mud discharge pipe that can discharge the soil cut by the cutter head on the excavation face. The components of the invention are simple and maintainable. Most of the components can be replaced and upgraded, and the core invention focuses on the dynamics between components. Coordination, so it has high practical value.

Description

technical field [0001] The invention belongs to the field of pipe jacking devices, and in particular relates to a device for quickly replacing the cutter head of a pipe jacking machine and a working method thereof. Background technique [0002] During the construction process of the pipe jacking machine, due to the need to continuously excavate the rock, the cutter head will be gradually damaged, thereby reducing the construction efficiency of the shield machine. In the traditional shield machine, due to the lack of a detection device for the cutter head, it is only necessary to stop for repairs after excavating for a period of time to check the cutter head. This inspection wastes a lot of time, and because the worn cutter head is not replaced in time, the local excavation strength is reduced, and the service life of other cutter heads is also affected. [0003] In the prior art, the replacement of the cutter head generally adopts semi-mechanical and manual replacement, whi...

AI Technical Summary

Problems solved by technology

This kind of inspection wastes a lot of time, and because the worn cutter head is not replaced in time, the local excavation strength is reduced, and the service life of other cutter heads is also affected

[0003] In the prior art, the replacement of the cutter head is generally semi-mechanical and manual replacement, which is time-consuming, laborious and dangerous

And the higher the cutter head is, the more difficult it is to replace

[0004] However, most of the existing semi-automatic or fully automatic cutter head replacement devices also have the disadvantages of large floor space, high cost, complicated devices, difficult maintenance, and insufficient consideration.
