Device for quickly replacing cutter head of pipe jacking machine and working method of device

Abstract

The invention relates to the technical field of pipe jacking machine cutterheads, in particular to a device for quickly replacing a cutter head of a pipe jacking machine and a working method of the device. The device is characterized in that a device front plate is an outer surface plate located on the front portion of a shield tunneling machine, the front plate is provided with a containing holefor containing the cutter head, and a cutter box can be installed on the rear portion of the front plate; the interior of the cutter box is used for containing a cutter head box, a sliding groove capable of limiting the cutter head box is formed in the inner side of the cutter box, and an upspring sealing button and a detection mechanical arm switch are oppositely arranged on the surface of the sliding groove to control a sealing plate lifting machine and a detection mechanical arm respectively; the cutter head box is provided with a cutter containing hole so that the cutter containing hole can be in communication with the front plate containing hole, and the cutter head installed in the cutter head box can protrude out of the front plate; and a drainage pipe for discharging the soil cut by the cutter head on the excavating surface is installed at the rear part. According to the device and the method thereof, the components are simple, the maintainability is good, most of the components can be replaced and upgraded, and the core invention focuses on the dynamic coordination among the components, so that the practical value is quite high.

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.
