Problems solved by technology

The rotatable cutter head at the front end of the TBM is a key part of the equipment. Excessive wear of the hob will cause problems such as reduced excavation efficiency and increased construction costs. Therefore, monitoring the wear status of the hob has become a key issue to ensure safe and effective TBM construction
[0003] Most of the hob wear monitoring devices in the prior art use sensor systems, sound waves, infrared or laser monitoring, etc., which will be affected by foreign objects on the hob surface during monitoring, cannot perform effective measurement, lack reliability, and are difficult to comprehensively detect Wear of the knife ring

Abstract

The invention discloses a TBM hob abrasion monitoring device and method based on machine vision. The TBM hob abrasion monitoring device comprises a controller, a moving device and a hob monitoring device body. The microcontroller can control the moving device so as to drive the hob detection device to move; when the hob monitoring device reaches a designated position, the microcontroller controlsthe industrial camera to shoot the hob, and the hob monitoring device can comprehensively monitor the abrasion condition of the hob ring of the TBM hob.

Description

technical field [0001] The invention belongs to the technical field of TBM equipment monitoring, and in particular relates to a machine vision-based TBM hob wear monitoring device and a monitoring method. Background technique [0002] With the rapid growth of my country's urban transportation, railways, highways, water conservancy, municipal engineering and other construction projects, my country's excavation machinery has developed rapidly. It is widely used in the field of tunnel engineering construction due to its advantages of safety, economy and so on. The rotatable cutter head at the front end of the TBM is a key part of the equipment. Excessive wear of the hob will cause problems such as reduced excavation efficiency and increased construction costs. Therefore, monitoring the wear status of the hob has become a key issue to ensure safe and effective TBM construction. [0003] Most of the hob wear monitoring devices in the prior art use sensor systems, sound waves, inf...
