Real-time abrasion monitoring device for cutter head of shield tunneling machine

Abstract

The invention relates to a real-time abrasion monitoring device for a cutter head of a shield tunneling machine. The real-time abrasion monitoring device comprises a cutter head end device, a signal receiving module, a PLC data processing module and a monitor. The cutter head end device is installed on the steel structure surface of a shield tunneling machine cutter head, the signal receiving module is installed on a soil cabin wall plate of a shield body of a shield tunneling machine, the cutter head end device is provided with a cutter head end monitoring assembly, the cutter head end monitoring assembly comprises a wear-resisting shell and a resistance wire, and the resistance wire penetrates through the interior of the wear-resisting shell. A signal sending module and a power module are further arranged in the wear-resisting shell, the signal sending module is connected with the resistance wire through a signal cable, the signal sending module and the signal receiving module are in communication transmission in a wireless signal mode, and the signal receiving module is connected with the PLC data processing module through a signal cable; the monitoring device can monitor the real-time wear value of the cutter head of the shield tunneling machine, feeds back the result to an operator in real time, and is not limited by any environmental factor or hardware factor.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a real-time wear monitoring device for a cutter head of a shield machine. Background technique [0002] During the excavation process of the shield machine, the cutter head of the shield machine will continue to wear out with the progress of the excavation. Most of the existing wear monitoring devices for the cutter head of the shield machine use a hydraulic circuit for detection. When the wear of the monitoring device reaches the limit value, leakage defects will appear, which will cause the pressure value in the hydraulic circuit to decrease and generate an alarm, resulting in the following technical problems: [0003] 1. The hydraulic circuit is used to monitor the cutter head, which cannot detect the wear amount of the cutter head in real time, but can only monitor whether the wear of the cutter head reaches the limit value of the cutter head; [0004] 2. The hydraul...
