An online real-time detection system and method for tbm hob wear

Abstract

The invention provides an online real-time detection system and method for TBM hob wear, which are used to solve the problems that the existing hob wear detection system is complex, greatly affected by the environment, and inaccurate in measurement accuracy. The detection system of the present invention includes an industrial computer, and the industrial computer is respectively connected with the laser telescopic device and the hob wear laser detector. On the cutter head, the hob wear laser detector is installed on the top of the laser telescopic device; the industrial computer is connected with the TBM main control room; and an online real-time detection method is disclosed at the same time. The invention can realize the real-time monitoring of hob wear in different tunneling environments, has a high degree of automation, and greatly reduces the maintenance risk of maintenance personnel; the invention is easy to operate, has reasonable protection devices, and can complete the hob within the step-changing time of the TBM Wear information collection ensures the real-time and accuracy of hob detection.

Description

technical field [0001] The invention relates to the technical field of wear monitoring of hob cutters of full-face boring machines, in particular to an online real-time detection system and method for wear of TBM hobs. Background technique [0002] With the country's large-scale construction investment in the field of infrastructure, TBM and shield machines have been widely used in various tunnels due to their advantages such as safety and speed. The cutting tool is a key part and a vulnerable part on the TBM. The wear mode of the hob includes normal wear and abnormal wear. The normal wear is caused by the abrasive effect of the rock on the cutting tool, which basically accounts for more than 80-90% of the cutting tool wear. The detection of hob wear is directly related to the improvement of engineering construction excavation efficiency and economic benefits, so the research on real-time detection of hob wear is very important for TBM construction. [0003] At present, the...
