A shield machine failure monitoring and early warning system and method

Abstract

The invention discloses a shield machine failure monitoring and early warning system and method. The system includes a host monitoring machine, a shield machine working condition detection device for real-time monitoring of the working condition information of the monitored shield machine, The controlled early warning prompt device and the timing circuit connected with the upper monitoring machine, the early warning prompt device is connected with the upper monitoring machine; the working condition detection device of the shield machine includes the main bearing working condition detection for real-time monitoring of the working condition of the main bearing of the shield machine device, a cutterhead detection device for real-time monitoring of the shield machine cutterhead, and a cutterhead drive detection device for real-time monitoring of the working conditions of the cutterhead drive system; the method includes steps: step 1, shield machine working condition monitoring and The monitoring information is uploaded synchronously; 2. Analysis and processing of shield machine working condition information. The invention can timely and accurately monitor the faults existing in the shield machine, and can give early warning prompts according to the monitoring results.

Description

technical field [0001] The invention belongs to the technical field of shield machine fault monitoring, and in particular relates to a shield machine fault monitoring and early warning system and method. Background technique [0002] 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, and tailor-made design and manufacture according to different geological conditions, the reliability requirements are extremely high. The status of core components such as the main bearing of the cutter head, the main drive reducer, the screw reducer, and the hydraulic system directly affect the construction period, safety, cost, and quality of the shield tunneling. Due to factors such as high mobility of personnel in construction units, uneven personnel levels, and complex construction environments, shield machines have...

AI Technical Summary

Problems solved by technology

During the excavation, the force on the cutter head is complex and the working environment is harsh, so it is a part that needs to be inspected and repaired.
