Abstract

The invention discloses a combined monitoring method for shield tunneling machine cutterhead damage. The combined monitoring method comprises the following steps that 1, a monitoring device is arranged; 2, detection data of an operation sensor of a shield tunneling machine are obtained; 3, the shield tunneling machine cutterhead damage is judged according to an acceleration sensor; 4, the shield tunneling machine cutterhead damage is judged according to an acoustic emission sensor; 5, the shield tunneling machine cutterhead damage is judged according to a temperature sensor; and 6, the shieldtunneling machine cutterhead damage is judged according to a hydraulic sensor. The combined monitoring method is simple in step, reasonable in design and convenient to implement, combined monitoring of the shield tunneling machine cutterhead damage is achieved through multiple sensors, and the accuracy of shield tunneling machine cutterhead damage judgment is improved.

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...
