A health status monitoring and early warning equipment for a plate rolling machine

Abstract

The invention, which belongs to the technical field of mechanical engineering, discloses a health state monitoring and early warning device for a veneer reeling machine. The health state monitoring and early warning device comprises a veneer reeling machine health monitoring system, a shutdown state evaluation system, a work starting state assessment system, a key component fatigue analysis system, and an early warning system. A temperature detection unit, a displacement detection unit and an acceleration detection unit are arranged in the shutdown state evaluation system. A displacement detection unit, an acceleration detection unit and a rotation speed detection unit are arranged in the work starting state assessment system. A strain information detection unit is arranged in the key component fatigue analysis system. According to the invention, key component strain information, shutdown state information, and work starting state information of the veneer reeling machine can be collected and monitored simultaneously, the fatigue damage accumulation information of the veneer reeling machine can be obtained quickly and timely, and the abnormal information can be warned early. The effectiveness is good. State information collection and early warning of the veneer reeling machine in a shutdown state can be realized; and thus the current performance of the veneer reeling machine can be obtained comprehensively and thus early warning can be carried out timely.

Description

technical field [0001] The invention relates to a machine health state monitoring and early warning equipment, in particular to a plate rolling machine health state monitoring and early warning equipment, which belongs to the technical field of mechanical engineering. Background technique [0002] At present, in terms of mechanical failure and diagnosis, the fault diagnosis of rotating machinery has been very mature, but the common practice is to collect the rotating machinery under the working state according to the tachometer, accelerometer and displacement meter installed on the machinery when the rotating machinery is working. Information to construct alarm indicators, when the collected signal is abnormal, the system will alarm. [0003] This approach has two shortcomings: one is the lack of reasonable life assessment information, which may lead to production accidents due to failure of certain key components due to life, especially fatigue life, but not being discovere...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a plate rolling machine health status monitoring and early warning equipment to solve the problem that the current plate rolling machine health monitoring system lacks the life early warning function of the key components of the plate rolling machine and the lack of collection and utilization of shutdown status information. technical problem
