Tunnel boring machine supporting cylinder joint vibration condition monitoring method

Abstract

The invention provides a tunnel boring machine supporting cylinder joint vibration condition monitoring method and belongs to the technical field of tunnel boring machine underground construction real-time monitoring. According to the tunnel boring machine supporting cylinder joint vibration condition monitoring method, vibration measuring points are reasonably distributed at cutterhead supportingcylinder joints; vibration sensors and a wireless data transmission system thereof are utilized to obtain monitoring data; an indirect prediction model is put forward to indirectly predict a positionwhich is difficult to monitor; and therefore, the long-term monitoring and prediction of the vibration conditions of the supporting cylinder joints of the cutterhead system of a TBM (tunnel boring machine) can be realized and timely fed back to an operator, and the occurrence of unexpected accidents can be prevented, and it can be ensured that the TBM works safely and reliably.

Description

technical field [0001] The invention relates to a method for monitoring the vibration at the joint of a cutterhead supporting oil cylinder of a full-section rock boring machine, and belongs to the technical field of real-time monitoring of underground construction of a full-section rock boring machine. Background technique [0002] Full-face tunneling equipment (abbreviated as TBM) is a large-scale underground tunneling equipment integrating multiple systems, and its application range is very wide at present. Due to the harsh environment of TBM excavation and the multi-point impact load generated during rock breaking, this will cause the TBM to generate relatively strong vibration, so the impact on the support part is also greater, and because the support part is based on oil cylinders and protection The shield connection realizes support, but severe vibration often causes vibration damage to the connection of the support cylinder. Therefore, it is very important to monitor ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are relatively few researches on the vibration monitoring scheme at the connection of the support cylinder of the TBM cutterhead system at home and abroad.

And because the working environment of the cutter head system is complex and changeable, it is also troublesome to arrange the measuring points

Although some scholars have done some research, they also use any safe position for measurement, so it has certain limitations, one-sidedness and large errors
