Abstract

The invention provides a shield tunneling machine cutterhead wear on-line measurement method, which utilizes a foam hole in an existing shield tunneling machine cutterhead, can realize on-line measurement through a hydraulic oil cylinder, a pressure sensor and a displacement sensor, reduces personnel pressurization construction, is simple in measurement device, is convenient for mastering the wearamount of a cutter at any time, and avoids delaying a construction period.

Description

technical field [0001] The invention belongs to a method for measuring wear of a cutter head, and more specifically relates to an online measurement method for wear of a shield machine cutter head. 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, ...
