Embodiment Construction

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference attachment figure 1 , The schematic diagram of the cutter head is shown. In order to improve the performance of excavating soil, a number of foam holes 1 are uniformly distributed on the cutter head 7. In this embodiment, there are 6 foam holes, and the leading knife on the cutter head is also Evenly distributed on the periphery of the cutter head.

[0025] The present invention provide...

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 the wear of a cutter head, and more specifically relates to an online measurement method for the wear of a cutter head of a shield machine. Background technique [0002] With the widespread use of shield machines in China and the continuous extension of the tunnel length in 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 tool usage. The earth pressure balance shield method is currently a common 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 pressurized conditions, which often require pressurized operations. This process is extremely troublesome and dangerous, and the pressureless operation method is often c...
