High-pressure water spraying auxiliary device for slurry balanced pipe jacking machine

Abstract

The invention discloses a high-pressure water spraying auxiliary device for a slurry balanced pipe jacking machine, and relates to the technical field of slurry balanced pipe jacking machines. In order to solve the problems that in the case of an existing slurry balanced pipe jacking machine, when a cutter disc is cleaned, a spraying head is difficult to incline and rotate up and down, so that thewhole disc surface of the cutter disc is difficult to clean in all directions, the following scheme is provided presently. According to the scheme, the high-pressure water spraying auxiliary device comprises a shell and a high-pressure water spraying opening, a cutter disc and a crushing chamber are arranged inside the shell, and a fixing sleeve is fixedly connected to the top side inside the crushing chamber. According to the high-pressure water spraying auxiliary device, through the design of a first spraying head and a second spraying head, the inner parts of the crushing chamber and the cutter disc are conveniently cleaned, soil is prevented from sticking to the crushing chamber and the cutter disc, through the design that the second spraying head inclines and rotates up and down, spray cleaning can be performed on a plurality of radial positions of the cutter disc conveniently, and due to the fact that the cutter disc rotates and works in the axial direction, the second sprayinghead can perform spray cleaning on the cutter disc in multiple directions.

Description

technical field [0001] The invention relates to the technical field of mud-water balance pipe jacking machines, in particular to a high-pressure water spray auxiliary device for mud-water balance pipe jacking machines. Background technique [0002] During the full-section cutting and jacking process of the mud-water balance pipe jacking machine, the mud pump is used to transport mud to the head cutter head and the crushing chamber, and then the cut soil is discharged to the ground through the mud pump. Compared with manual pipe jacking, mud-water balance pipe jacking has high construction costs. However, when the geological conditions are quicksand, it is safer to use mud-water balance mechanical pipe jacking than manual pipe jacking. When mud-water balance pipe jacking machines on the market encounter cohesive soil, the entire cutter head And the crushing bin will be full, resulting in a decline in construction efficiency. [0003] For example, the high-pressure water spra...
