A mud-water balance shield machine auxiliary tool change device and its use method

Abstract

The invention provides an auxiliary tool changing device for a mud-water balance shield machine and a method of using the same. The front end of the mud-water balance shield machine is a cutterhead, and an excavation cabin, an air cushion cabin and a man-lock cabin are arranged in sequence behind the cutterhead; The auxiliary tool changing device includes: a first slide rail fixed on the upper part of the air cushion cabin, a mobile slide table embedded on the first slide rail, the robot is fixed on the mobile slide table, and a second slide rail is installed on the lower part of the human lock cabin. The transport rack is set up on the second slide rail. The upper end of the transport rack is provided with a second mounting seat. The tool changing mechanical arm is installed on the second mounting seat. The front end of the tool changing mechanical arm is equipped with a lighting and camera device. Without changing the original shield machine cabin door and space structure, the added auxiliary tool changing device can effectively improve the tool changing efficiency, reduce tool changing costs, ensure the safety of operators, complete tool wear detection and replacement, and improve It improves the automation level of the mud-water balance shield machine's tool changing operation and achieves reasonable, safe and efficient tool changing operations.

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 ...

AI Technical Summary

Problems solved by technology

Among them, normal pressure tool change has high requirements on geological conditions, which is not easy to meet; the technical threshold of pressure tool change is high, and many construction units have not yet mastered the key technology of shield machine with pressurized cabin operation; and the use of shaft tool change takes a long time, Great damage to the environment, and not suitable for construction in some important places in the city

In addition, the above tool changing techniques all require the operator to enter the excavation cabin, and the environment in the cabin is harsh, especially the tool change under pressure. The high pressure environment will cause the operator to bear great safety risks
