Abstract

The invention discloses a method for judging damage of a shield tunneling machine cutterhead. The method comprises the following steps that 1, a monitoring device is arranged; 2, detection data of operated sensors of a shield tunneling machine are obtained; 3, the damage of the shield tunneling machine cutterhead is judged according to an acceleration sensor; 4, the damage of the shield tunnelingmachine cutterhead is judged according to an acoustic emission sensor; and 5, the damage of the shield tunneling machine cutterhead is judged according to a hydraulic sensor. The method is simple in step, reasonable in design and convenient to implement, the damage of the shield tunneling machine cutterhead is judged, and the judgment accuracy of the damage of the shield tunneling machine cutterhead is improved.

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...
