Intelligent-type shield tunneling machine main bearing provided with physical condition monitoring

Abstract

The invention relates to an intelligent-type shield tunneling machine main bearing provided with physical condition monitoring. The intelligent-type shield tunneling machine main bearing comprises a shield tunneling machine main bearing mechanical structure, a wireless data acquisition terminal, and a background monitoring terminal; the shield tunneling machine main bearing mechanical structure is used for arranging a sensor unit in the shield tunneling machine main bearing so as to realize collection and transmission of physical condition parameters of the intelligent-type shield tunneling machine main bearing under running states; the intelligent-type shield tunneling machine main bearing is provided with a bearing inner ring, a bearing outer ring, a rolling element, and a holder. The intelligent-type shield tunneling machine main bearing is provided with the mechanical structure, and a wireless transmission-based physical condition data physical condition intelligent monitoring system is provided for collection and transmission of parameters such as temperature increasing value, vibration value, and wearing capacity of the intelligent-type shield tunneling machine main bearing, so that monitoring on the main bearing physical conditions is realized under running states without disassembling shield tunneling machine host equipment, running states of the intelligent-type shield tunneling machine main bearing can be obtained in real time, fault locating can be realized in time, failure cause can be identified in time, equipment safety and stability are improved greatly, and maintenance cost and maintenance time are reduced.

Description

technical field [0001] The invention relates to the field of shield machine main bearings, in particular to an intelligent shield machine main bearing with health status monitoring. Background technique [0002] The main bearing of the shield machine is the core component of the shield tunneling machine, which plays a role in supporting the shield cutter head and making it rotate to break rock. The main bearing of the shield machine works under heavy load and low speed conditions, and bears the combined action of axial force, radial force and overturning moment load. The main bearing of the shield machine works in a confined underground space, with poor heat dissipation and harsh working conditions. It is difficult to judge the fault point when a fault occurs. The shield machine is not allowed to have any faults in a given construction section, and the life and reliability of the main bearing as the core component directly affects the construction safety of the shield machi...
