Abstract

The invention discloses a hobbing cutter changing mechanical hand for a large-diameter slurry shield machine. The hobbing cutter changing mechanical hand comprises a pedestal, a mechanical telescopic arm and a cutter changing device. Integral positioning is realized by integrally moving on a material bin guide rail and extending and retracting the mechanical telescopic arm; the cutter changing device comprises a housing, a bolt dismounting module, a wedge block dismounting module, a pressure block dismounting module and a hobbing cutter dismounting module; and the bolt dismounting module, the wedge block dismounting module, the pressure block dismounting module and the hobbing cutter dismounting module are arranged on the housing for dismounting bolts, pressure blocks, wedge blocks and the hobbing cutters. The hobbing cutter changing mechanical hand can replace manual work to perform hobbing cutter changing operation, so that personal safety of a constructor is guaranteed, economic cost is reduced and cutter changing efficiency is improved.

Description

technical field [0001] The invention relates to a tool changing device for a shield tunneling machine, in particular to a hob tool changing manipulator for a large-diameter muddy water shield machine. Background technique [0002] As the core component of mud-water balance shield machine excavation, the cutting tool directly interacts with the soil and rock ahead, especially under geological conditions such as boulders, bedrock protrusions, soft top and hard bottom, there are common problems of serious wear and fracture failure. If a single cutter in the shield cutter group is severely worn, it will affect the overall rock-breaking performance of the cutter group, so it is inevitable to check and replace the cutter in time. At this stage, muddy water shields can only be manually pressed into the chamber to change tools under water. This operation method is not only high in economic cost, difficult in operation, and low in efficiency, but also has great danger and is prone to...
