Shield tail brush capable of monitoring abrasion in real time and shield tail brush abrasion real-time monitoring system

Abstract

The invention discloses a shield tail brush capable of monitoring abrasion in real time and a shield tail brush abrasion real-time monitoring system. The shield tail brush comprises a base, a first protection plate and a second protection plate, the first protection plate and the second protection plate are arranged on the base, and a brush wire layer is arranged between the first protection plate and the second protection plate; the shield tail brush further comprises an optical fiber abrasion sensor arranged between the first protection plate and the second protection plate, the optical fiber abrasion sensor is provided with an abrasion part relatively far away from the base, the optical fiber abrasion sensor can be connected with a controller, and when the abrasion part is abraded, the optical fiber wear sensor loses the reflecting capacity of the corresponding wavelength. According to the shield tail brush capable of monitoring abrasion in real time and the shield tail brush abrasion real-time monitoring system, the sealing state of the shield tail brush can be monitored in real time, data are real-time, and judgment is accurate.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a shield tail brush for real-time wear monitoring and a shield tail brush wear real-time monitoring system. Background technique [0002] With the development of the economy, in order to alleviate the ground traffic, more and more cities have begun to construct subway tunnels, and the shield machine is the most important equipment in the construction of subway tunnels. In order to prevent groundwater, mud, and grouting fluid from leaking into the shield machine, a shield tail brush is installed at the tail of the shield machine. The seal of the shield tail brush plays a vital role in ensuring the tunneling of the shield and the smooth construction of the project. When the shield tail brush is worn, its sealing effect will be affected. If the wear of the shield tail brush is not detected in time, resulting in mud channeling and leakage at the shield tail, it will cause a ...

AI Technical Summary

Problems solved by technology

When the shield tail brush is worn, its sealing effect will be affected. If the wear of the shield tail brush is not detected in time, resulting in mud channeling and leakage at the shield tail, it will cause a large cost loss to the engineering construction , and even bring huge risks to construction safety

However, there is currently no system for monitoring the wear of the tail brush plate
