Shield TBM oil liquid state on-line automatic monitoring system

Abstract

The invention belongs to the technical field of shield machine lubrication condition monitoring, and proposes a shield TBM oil liquid state on-line automatic monitoring system. The proposed shield TBM oil liquid state on-line automatic monitoring system includes a planetary gear oil tank (1), a main bearing gear main oil tank (2) and an on-line monitoring acquisition control part (9); the on-line monitoring acquisition control part (9) has a plurality of solenoid valves (7); the plurality of solenoid valves (7) and a plurality of planetary gear oil tanks in a shield machine gear oil lubrication system are in one-to-one correspondence; the plurality of solenoid valves are cyclically opened in an on-line monitoring period, and only one is in a normally open state; the on-line automatic monitoring system is also provided with an oil liquid monitoring loop (5); the other ends of the plurality of solenoid valves (7) communicate with the oil liquid monitoring loop (5); and the oil liquid monitoring loop (5) is connected with the on-line monitoring acquisition control part (9). The shield TBM oil liquid state on-line automatic monitoring system provided by the invention ensures reliable lubrication of equipment and safe operation of a shield machine.

Description

technical field [0001] The invention belongs to the technical field of shield machine lubrication state monitoring, and relates to a shield machine lubrication system operating state detection technology, in particular to an online automatic monitoring system for shield TBM oil state. Background technique [0002] Shield machine is the main construction machine in underground excavation and shield construction. It has been widely used in large-scale tunnel projects such as urban subways, river-crossing highway tunnels, and sea-crossing tunnels in my country. The main bearing of the shield machine is the core component of the shield machine, which plays a role in supporting the shield cutter head and making it rotate to break rock. The technology of lubrication and wear status monitoring and fault diagnosis of the shield machine is changing with each passing day, which is an important guarantee for continuously improving the safe operation of the shield machine. If the lubri...

AI Technical Summary

Problems solved by technology

If during the construction process, the main bearing lubricating oil leaks or mud, gravel and slag enter the main bearing lubrication system, it will cause rapid damage to the main bearing and gear pair; the damaged main bearing needs to be lifted out from the shaft excavated above the shield machine Replacement is very difficult and will bring immeasurable losses to shield construction
