Auxiliary tool changing device of slurry balance shield tunneling machine and application method of auxiliary tool changing device

Abstract

The invention discloses an auxiliary tool changing device of a slurry balance shield tunneling machine and an application method of the auxiliary tool changing device. A tool disc is arranged at the foremost end of the slurry balance shield tunneling machine. An excavation cabin, an air cushion cabin and an entry gate cabin are sequentially arranged behind the tool disc. The auxiliary tool changing device comprises a first sliding rail fixedly connected to the upper portion of the air cushion cabin and a moving sliding table embedded in the first sliding rail. A robot is fixedly connected to the moving sliding table, a second sliding rail is arranged at the lower portion of the entry gate cabin, and a conveying frame is erected on the second sliding rail. A second installing base is arranged at the upper end of the conveying frame. A tool changing mechanical arm is arranged on the second installing base, and a lighting and camera shooting device is arranged at the front end of the tool changing mechanical arm. On the basis that an original shield tunneling machine cabinet door and a space structure are not changed, the auxiliary tool changing device is additionally arranged, the tool changing efficiency can be effectively improved, the tool changing cost is reduced, the safety of operators is guaranteed, and the tool abrasion detecting and replacing are finished. The automation level of the tool changing work of the slurry balance shield tunneling machine is improved, and reasonable, safe and efficient tool changing work is achieved.

Description

Technical field: [0001] The invention relates to the technical field of engineering machinery, in particular to an auxiliary tool changing device for a mud-water balance shield machine and a method for using the same. Background technique: [0002] During the operation of the shield machine, the cutter head is mainly used to complete the crushing and stripping of the rock and soil on the tunnel face. During construction, the shield tunneling machine will encounter various complex strata, so the stress on the cutter head is quite complicated, which can easily cause wear on the cutter head, which seriously restricts the tunneling efficiency of the shield machine. The research on the above problems is mainly divided into two aspects: one is to improve the service life of the shield machine tool; the other is to develop the corresponding technology for shield machine tool change. [0003] At present, the relatively mature tool change technologies mainly include normal pressure ...
