Abstract

The invention discloses a method for judging the damage of a shield machine cutter head. The method comprises the following steps: 1. Laying out a monitoring device; 2. Acquisition of detection data from a shield machine running sensor; Judgment of cutter head damage; 4. Judgment of shield machine cutter head damage based on acoustic emission sensor; 5. Judgment of shield machine cutter head damage based on hydraulic sensor. The method of the invention has simple steps, reasonable design and convenient implementation, realizes the judgment of the damage of the cutter head of the shield machine, and improves the accuracy of judgment of the damage of the cutter head of the shield machine.

Description

technical field [0001] The invention belongs to the technical field of damage judgment of a shield machine cutter head, and in particular relates to a method for judging 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 the shield m...
