Problems solved by technology

[0003] During the excavation process of the shield machine, the force state of the hob is relatively complicated, and the hob is generally surrounded by mud, gravel, etc., and the working environment is relatively harsh, which is not conducive to the arrangement of sensors and signal transmission equipment on the hob. Therefore, At present, there is no feasible solution to monitor the force state of the hob

Abstract

The invention discloses a hob holder for detecting stress of a hob, and a hob assembly. The hob holder for detecting the stress of the hob comprises a supporting main body which comprises a positioning groove, through holes and deformation sensors; the positioning groove is formed by extending in the thickness direction of the supporting main body and used for storing a connection part of a hob shaft; the through holes penetrate through the hob holder for detecting the stress of the hob in the thickness direction; and the deformation sensors are arranged in the through holes and used for detecting the deformation of the through holes. The hob assembly comprises the hob holder for detecting the stress of the hob. According to the hob holder and the hob assembly, the through holes can be formed in the supporting main body of the hob holder, the deformation sensors are arranged in the through holes to detect the stress situation of the hob in the tunnel digging process, thus the working state of the hob can be analyzed in real time, and the abrasion situation of the hob is analyzed.

Description

technical field [0001] The invention belongs to the technical field of shield equipment, and in particular relates to a hob cutter seat and a hob assembly for detecting the hob force. Background technique [0002] The shield machine is a machine for excavating tunnels based on the full-face excavation method. It mainly realizes rock breaking or soil excavation in tunnel excavation through the hob installed in the cutter box on the cutter head. The hob is a vulnerable part on the cutter head of the shield machine. It will wear out during the interaction with rock and soil. When the hob is worn to a certain extent, it will affect the normal operation of the shield machine. Therefore, in the process of excavating the tunnel, it is necessary to constantly monitor the stress on the cutter shaft of the hob to analyze the working state of the hob and the wear of the hob. [0003] During the excavation process of the shield machine, the force state of the hob is relatively complica...
