Abstract

The invention discloses an earth pressure balance shield machine hob abrasion monitoring device and method based on image analysis. The earth pressure balance shield machine hob abrasion monitoring device comprises a hob monitoring device, wherein the hob monitoring device is arranged in a pressure-bearing sealing device, and the hob monitoring device is opposite to a hob box assembly. The deviceis simple in structure, convenient to install and clear in visual field, has the characteristic of being good in protection effect and flushing effect, and provides a stable and reliable structural basis for image analysis and processing. Online measurement of tool abrasion can be achieved through the abrasion monitoring method. Meanwhile, the hob state is directly observed through the monitoringvideo, and the safety, convenience, economical efficiency and reliability of hob abrasion monitoring are improved.

Description

technical field [0001] The invention belongs to the technical field of earth pressure balance shield machine equipment, and in particular relates to an image analysis-based hob wear monitoring device and method for earth pressure balance shield machine. Background technique [0002] Tunnel shield construction has been widely used for its advantages of safety, efficiency, economy and little impact on the ground environment. The earth pressure balance shield machine is generally constructed in soft soil or compound stratum, especially in the compound stratum, the earth pressure balance shield machine is generally equipped with a hob and a scraper at the same time, with the excavation of the shield machine, the wear of the hob It is inevitable. At present, the common monitoring methods of hob wear include odorant addition method, sensor monitoring method, tunneling parameter analysis method, rock slag shape analysis method, and cabin inspection method. The odor additive metho...
