Abstract

The invention relates to the technical field of pipe jacking machines, and particularly relates to an efficient device for replacing hobbing cutters of a pipe jacking machine and a using method of theefficient device. The device comprises a rotating part, wherein the rotating part comprises a first cutter disc, a second cutter disc, an auxiliary cutter disc, a central part, a rolling bearing, a working space, supporting legs, a pressure chamber and a shell. According to the efficient device, the first cutter disc or the second cutter disc is returned into the shell, so that an operator can conveniently replace the hobbing cutters, and the hobbing cutter replacing efficiency is improved; after the hobbing cutter on the first cutter disc is damaged, the second cutter disc is rapidly replaced to continue to work, and the hobbing cutters are replaced in a unified mode until the hobbing cutters on the first cutter disc and the second cutter disc are all damaged, so that the cutter replacing efficiency is improved due to the fact that the device can continuously work and the operator can replace the hobbing cutters in a centralized mode; and the first cutter disc or the second cutter disc is returned into the shell, so that the operator can replace the hobbing cutters at the rear part, and the problem of casualties caused by improper operation is reduced.

Description

technical field [0001] The invention relates to the technical field of pipe jacking machines, in particular to an efficient hob replacement device for pipe jacking machines and a method for using the same. Background technique [0002] A pipe jacking machine is used during tunnel construction. The pipe jacking machine is equipped with a pipe jacking cutter head, and the pipe jacking machine cutter head is provided with a hob for breaking rocks during excavation. However, the hob is prone to wear and tear during rock breaking, so the hob needs to be replaced. [0003] In order to make up for the above shortcomings, the Chinese authorized patent No. CN103987921B "Drill Bit Replacement Method and Drill Bit Replacement Device for Shield Tunneling Machine" was invented. By providing an operating space in the pipe jacking machine, the operator can enter the operating space to replace the hob; The technical effect achieved is that the damaged hob on the cutter head can be replaced...
