Mechanical device for quickly replacing multiple pipe jacking machine tool bits

Abstract

The invention relates to the technical field of pipe jacking machine tool bits, in particular to a mechanical device for quickly replacing multiple pipe jacking machine tool bits. The mechanical device comprises a tool bit replacing device, a rotating machine, a container, a rear plate and a front plate, wherein the tool bit replacing device is connected onto electric slide rails of the rear platethrough a supporting arm, a row of longitudinal electric sliding rails need to be installed on the rear portion of each row of tool boxes, the supporting arm can freely move the tool bit replacing device on rails of the electric sliding rails arranged on the rear plate under the cooperation of the supporting arm and a fixed arm installed on the rotating machine, a controlling machine is connectedto the interior of an inner rotating shell through the supporting arm and a fixing shaft, and a controller is kept fixed by directly facing a detection hole, and the controlling machine is provided with an observation camera relative to the other side of the supporting arm. According to the mechanical device, free adjustment can be conducted along the earth pressure balance bin rear plate of thepipe jacking machine freely, the damage condition of the tool bits of the whole tool bit of the pipe jacking machine can be checked in real time, the man-machine effect is improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the mechanical field of pipe jacking machine cutter heads, in particular to a mechanical device for quickly replacing a plurality of pipe jacking machine cutter heads. 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 pipe jacking machine, so the cutter head needs to be replaced. In the traditional method for replacing the cutter head of the pipe jacking machine, due to the lack of a device for quickly replacing the cutter head, it is only possible to dig for a period of time and the whole machine must be shut down for refurbishment, inspection and replacement of the cutter head. This kind of inspection and replacement wastes a lot of time due to the cumbersome steps, difficult operation and complicated replacement environment. [0003] In the...

Problems solved by technology

This kind of inspection and replacement is a waste of a lot of time due to the cumbersome steps, difficult operation, and complicated replacement environment.

[0003] In the prior art, the replacement of the cutter head is generally done manually, which is time-consuming, labor-intensive, and has a high risk, and the requirement for manpower is relatively high

And it is more difficult to replace the cutter head at a higher position, and most of the existing semi-automatic or fully automatic cutter head replacement devices also have the disadvantages of harsh conditions of use, high cost, complicated devices, difficult maintenance, and insufficient consideration.
