Mechanical device for semi-automatically replacing tool bit of tube push bench

Abstract

The invention discloses a mechanical device for semi-automatically replacing a tool bit of a tube push bench. The mechanical device comprises a front plate and a rear plate, wherein the front plate is mounted on an outer surface plate at the front part of a rack of the tube push bench, a plurality of containing holes are formed in the front plate, a tool box is installed at the positions, located on the rear portion of the front plate, of the containing holes, a tool bit box is installed in the tool box, a sliding groove is formed in the side edge of the interior of the tool box, a mud discharging pipe is arranged at the rear end of the tool bit box and matched with the containing holes, a baffle is installed on the rear portion of the tool box, the rear plate corresponds to the front plate in position and is located behind the front plate, a motor sliding rail is installed on the surface of the rear plate, a rotating motor is arranged at the upper end of the interior of the motor sliding rail, a coil winder is arranged at one end of the rotating motor, the rotating motor is connected with the coil winder through a rotating shaft, and a stretching line is wound on the coil winder. According to the mechanical device, tool bits are disassembled through semi-automatic machinery, and the situation that workers work in the high-humidity and high-pressure environment is avoided, and meanwhile, the tool bits at different heights and positions in the tool disc are rapidly disassembled and assembled.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking machine cutter head devices, in particular to a mechanical device for semi-automatically replacing the 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 (patent document: CN103987921B), the replacement of the cutter head generally adopts manual repla...

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 prior art (patent document: CN103987921B), 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

At the same time, most of the existing semi-automatic or fully automatic cutter head replacement devices also have the disadvantages of large space occupation, high cost, complicated devices, difficult maintenance, and insufficient consideration.
