Abstract

The invention provides a measuring device for mechanical-electrical-hydraulic coupling vertical vibration of a screw-down system of a rolling mill, and belongs to the technical field of fault detection of rolling mills. The measuring device is characterized in that real-time detection on mechanical-electrical-hydraulic coupling vertical vibration is realized, signals are collected from mechanics, electrics and hydraulic pressure, and the mechanical-electric-hydraulic coupling vertical vibration of the rolling mill can be detected and warned in an online manner by processing and analyzing the signals. When the rolling mill is in a mechanical-electrical-hydraulic coupling vertical vibration state, the measuring device can give an alarm in time and reminds operators of taking necessary treatment measures, and safe running of the rolling mill is guaranteed. The measuring device has a quite high economic benefit and high application value for enterprises.

Description

technical field [0001] The invention relates to a measuring device for electro-hydraulic coupling vertical vibration of a rolling mill pressing system, which belongs to the technical field of rolling mill fault detection. Realize online detection and early warning of electromechanical-hydraulic coupling vibration faults in rolling mill pressing system. Background technique [0002] The rolling mill is a metal pressure processing equipment that makes the rolled piece pass through the rolls with a certain roll gap to roll out a strip of expected thickness. It is one of the important equipment for rolling steel. The rolling mill pressing system integrates multiple subsystems such as machinery, electronics, and hydraulics. Under the action of disturbance, it is very easy to generate electromechanical-hydraulic coupling vertical vibration. Research shows that when the fifth octave vertical vibration with a frequency of 500~700Hz occurs Sometimes it will cause alternating light a...
