Abstract

The invention provides an online measuring device of cutterhead abrasion of a shield tunneling machine. The online measurement can be realized by using foam holes in a cutterhead of an existing tunneling machine through a hydraulic oil cylinder, a pressure sensor and a displacement sensor; the personnel pressurized construction is reduced; the measuring device is simple; the abrasion quantity of acutter can be conveniently mastered at any time; and the construction period delay is avoided.

Description

technical field [0001] The invention belongs to an online measuring device for cutter head wear, and more specifically relates to an online measuring device for cutter head wear of a shield machine. Background technique [0002] With the widespread use of shield machines in China and the continuous extension of the tunnel length of a single excavation, tool wear has become a key issue affecting the quality and progress of the project. As an important part of the shield machine, the cutter head is of great significance for regular inspection and maintenance and accurate grasp of the usage of the cutter. The earth pressure balance shield method is currently a commonly used shield method. In order to detect the wear of the cutter head, in this case, the cutter head inspection and tool maintenance are carried out under pressure, which often requires pressure operation. This process is extremely cumbersome and dangerous, and the non-pressure operation method is often cumbersome,...
