Abstract

The invention provides a TBM vibration hydraulic state monitoring system. The system comprises a three-axis vibration acceleration sensor, a pressure sensor, a signal conditioning board and a signal collecting system. The three-axis vibration acceleration sensor is installed in the position, large in vibration, on a TBM host and used for detecting vibration acceleration and outputting a pressure signal. The pressure sensor is installed in a TBM hydraulic system and used for detecting the pressure of the hydraulic system and outputting a current signal. The signal conditioning board converts the current signal into a voltage signal to be output. The signal collecting system collects the voltage signal output by the three-axis vibration acceleration sensor and the signal conditioning board, and accordingly online continuous monitoring of TBM vibration and the hydraulic state is achieved. On the basis of the monitoring system, continuous collecting of TBM vibration and hydraulic signals can be achieved, the state of a whole machine is continuously monitored, and a data basis is provided for health monitoring of the whole TBM machine.

Description

technical field

[0001] The invention belongs to the field of equipment health monitoring, and in particular relates to the hydraulic and vibration state monitoring of a hard rock tunnel boring machine (TBM). Background technique

[0002] Tunnel Boring Machine (TBM for short) is a comprehensive equipment that mechanically breaks rocks, slags and supports for continuous operation. TBM is a highly complex engineering machinery, which integrates mechanical, electrical, hydraulic, sensing and information technologies. It has the functions of excavating and cutting soil, conveying soil muck, assembling tunnel lining, measuring, guiding and correcting deviations, etc. It has been widely used Used in subway, railway, highway, municipal, hydropower tunnel projects. Aiming at the problem that the vibration of the whole machine is large during TBM work, which has a certain impact on the hydraulic system and mechanical structure, a set of synchronous monitoring system for the hydraulic...
