Abstract

The invention discloses a joint monitoring method for the damage of a shield machine cutter head. The method comprises the following steps: 1. the layout of a monitoring device; 2. the acquisition of the detection data of the shield machine operating sensor; 4. Judging the damage of the shield machine cutter head according to the acoustic emission sensor; 5. Judging the damage of the shield machine cutter head according to the temperature sensor; 6. Carrying out the damage of the shield machine cutter head according to the hydraulic sensor judgment. The method of the invention has simple steps, reasonable design and convenient implementation, realizes joint monitoring of the damage of the shield machine cutter head through a variety of sensors, and improves the accuracy of the judgment of the shield machine cutter head damage.

Description

technical field [0001] The invention belongs to the technical field of damage monitoring of a shield machine cutter head, and in particular relates to a joint monitoring method for damage of a shield machine cutter head. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield is that the "shield" (referring to the supporting segment) of the tunnel is constructed (laid) by the roadheader while excavating. The shield machine is a high-value-added complex equipment integrating advanced technologies such as machinery, electricity, hydraulic pressure, optics, network, automatic control, sensing, and information. And other functions, reliability requirements are extremely high. The shield machine is a large-scale excavation equipment for tunnel construction, and the cutter relies on the rotation of the cutterhead to cut and excavate the rock formation. The cutter head is the core component of t...
