Test bed and method for static detection of abnormal vibration of cutter of full-face tunnel boring machine

Abstract

The invention belongs to the technical field of full-face tunnel boring machine tool anomaly detection. The invention discloses a static detection test bed for abnormal vibration of a cutter of a full-face tunnel boring machine. The static detection test bed comprises a container body, a supporting door frame, a cutter box seat, a cutter conveying trolley, a protective cover, a warm air unit, a spraying unit, a control cabinet and a detection sensor, a lifting unit is arranged between the cutter box seat and the supporting door frame, and a vibration motor is arranged on the cutter box seat; the cutter conveying trolley is arranged in the container body in a walking mode, a cutter supporting tool is arranged on the cutter conveying trolley, and a crane is arranged on the side portion of the supporting door frame. The protective cover is arranged on the outer sides of the supporting door frame and the cutter box seat in a covering manner; and the detection sensor is used for acquiring detection data of the cutter. The invention further discloses a static detection method for abnormal vibration of the cutter of the full-face tunnel boring machine. The vibration detection signals of different abnormal damaged cutters are collected, accurate recognition of the cutters is facilitated, the tunneling performance of the tunneling machine is optimized, and the service life of the cutters is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tool abnormality detection for full-section tunnel boring machines, and in particular relates to a static detection test bench and method for tool abnormal vibration of full-section tunnel boring machines. Background technique [0002] The full-section tunnel boring machine is the main equipment for tunnel excavation, and the cutting tool is the core component of the full-section tunnel boring machine. As the core component, the cutter rolls on the surface of the soil to realize the peeling and excavation of the tunnel soil. Ideally, the wear of the tool is uniform, which is what the construction unit most wants to obtain. However, a large number of engineering cases show that most of the wear and damage of the tool are abnormal, and eccentric grinding of the knife ring and edge chipping often occur. In these two cases, the ideal distance between adjacent cutters cannot be realized, which makes the entir...

Problems solved by technology

At present, there are very few researches at home and abroad on the online monitoring of tool abnormal damage of full-face tunnel boring machines, which are limited to eddy current, magnetic sensing, odor method, hydraulic method, etc. Although the above sensing technologies have been applied in actual working conditions, but not good

The working environment of full-face tunnel boring machine tools is harsh, the working conditions are complicated, and mutual interference is serious
