Mechanical device for replacing tool bit of tube push bench

Abstract

The invention relates to the technical field of tube push bench cutter heads, in particular to a mechanical device for replacing a tool bit of a tube push bench. The mechanical device comprises a front plate, the front plate is the outer surface plate located on the front part of a machine frame, the front plate has a containing hole for containing the tool bit, a toolbox is installed on the rear portion, a motor sliding rail making an auxiliary arm slide in the direction of the containing hole is installed on the side part, the front portion of the toolbox is installed on the rear portion of the front plate, a tool bit box is contained inside the toolbox, the side edge of the toolbox is provided with a sliding groove capable of limiting the tool bit box, the sliding groove enables a mud discharging pipe on the rear portion of the tool bit box to make contact with the containing hole formed in the front plate and enables the tool bit to protrude out of the front portion of the front plate, the motor sliding rail enabling a baffle to move up and down is arranged on the rear portion of the toolbox, a mud discharging hole is formed in the upper end of the rear portion of the baffle, and can contain the mud discharging pipe arranged on the tool bit box. According to the mechanical device, the tool bit does not need to be replaced manually, the working efficiency of the tube push bench is improved, loading and unloading of the tool bit can be completed through remote control, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking machine cutter heads, and in particular relates to a mechanical device for replacing a pipe jacking machine cutter head. Background technique [0002] During the construction process of the pipe jacking machine, due to the need to continuously excavate rocks, the cutter head will be gradually damaged, thereby reducing the construction efficiency of the pipe jacking machine. In the traditional pipe jacking machine, due to the lack of a device for quick replacement of the cutter head, it can only be excavated for a period of time and must be stopped for repairs, 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 prior art, the replacement of the cutter head is generally done manually, which is time-consuming, laborious, and dangerous...

AI Technical Summary

Problems solved by technology

Due to the cumbersome steps, difficult operation and complex replacement environment, this kind of inspection and replacement wastes a lot of time

[0003] In the existing technology, the replacement of the cutter head is generally done manually, which is time-consuming, laborious, and very dangerous, and requires relatively high manpower.

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

Therefore, the existing technology / design is flawed

[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.
