Abstract
The invention relates to the technical field of vertical grinders and aims to solve the problems that the grinding roller bearings of the existing vertical grinders are difficult to accurately detect when the grinding roller bearings are damaged, the protection measures cannot taken on time for the accident damage, and the normal operation of equipment is influenced and the like. The technical scheme adopted by the invention is as follows: a grinding roller bearing monitoring mechanism comprises a grinding roller, a grinding roller shaft and a grinding roller bearing, wherein a vibration sensor for monitoring the vibration frequency of the grinding roller shaft is mounted on the grinding roller shaft; a mounting hole with an inner thread is processed in the axial end of the grinding roller shaft; an outer thread in threaded connection with the inner thread of the mounting hole is processed in the exterior of the end of the vibration sensor; each object has an inherent frequency spectrum; the grinding roller bearing, the grinding roller shaft and the vibration sensor are rigidly connected with each other; the vibration sensor can collect the vibration frequency spectrum of the bearing and can monitor the bearing on line; when the bearing has slight damage, the vibration frequency spectrum has abnormal fluctuation, the vibration sensor can capture the frequency spectrum and subsequently display the frequency spectrum to equipment maintenance staff; and the maintenance staff can carry out planned maintenance or replacement of the bearing according to the situation.
Description
Technical field
The invention belongs to vertical mill technical field, more particularly to the testing agency of the grinding roller bearing of vertical mill.
Background technology
Vertical mill is a kind of preferably large-scale milling equipment, is widely used in cement, electric power, metallurgy, chemical industry, nonmetallic
The industries such as ore deposit.It collects broken, dryings, grinding, classification and is transported in one, and production efficiency is high, can be by block, graininess and powdery original
Material wears into required granular material.
Burnisher apparatus are the parts that vertical grinder is used to mill, and belong to vertical mill pith.Burnisher apparatus are built with axle
Hold, when grinding machine runs, bearing is rotated always.The operation of monitoring bearing at present, the main temperature by monitoring bearing
Degree, and check whether bearing oil the inside has the modes such as foreign matter.But the defect of these monitoring methods is, different when detecting
When often, bearing is had occurred and that than more serious damage, and equipment must be out of service immediately, can cause unexpected shadow to production
Ring.
The content of the invention
The present invention provides a kind of grinding roller bearing mechanism for monitoring, for solving to be difficult to during existing vertical grinder roll bearing damage
Accurate detection, so as to arrange when causing and damaging not as good as anti-, affects normal operation of equipment etc..
To achieve these goals, the technical solution used in the present invention is：
A kind of grinding roller bearing mechanism for monitoring, including grinding roller, shaft of grinding roller and the grinding roller bearing between grinding roller and shaft of grinding roller, in mill
The vibrating sensor of monitoring shaft of grinding roller vibration frequency is installed on roller and/or shaft of grinding roller.
The processor for also including the information for processing vibrating sensor and the display for showing vibrating sensor in real time, processor
Early warning rumble spectrum scope is inside preset with, when the rumble spectrum of vibrating sensor monitoring is in early warning rumble spectrum setting range
When, show abnormal on display.
The preset alarm rumble spectrum value in processor, also including alarm, when the rumble spectrum of vibrating sensor monitoring
During more than warning rumble spectrum value, processor control alarm equipment alarm.
Described alarm is voice guard and/or flash alarm.
A tapped installing hole is machined with the axial end portion of described shaft of grinding roller, vibrating sensor end outside adds
Work has and is threadedly coupled external screw thread with installing hole internal thread.
Described vibrating sensor exterior circumferential is provided with diameter greater than the externally threaded compressed part of vibrating sensor, and described shakes
The threaded end of dynamic sensor to the distance between compressed part less than installing hole depth, in vibrating sensor compressed part and mill
Stay made by quality of rubber materials is provided between roll shaft.
Described compressed part is in circumferentially polygonized structure.
Beneficial effects of the present invention：Each object has its intrinsic frequency spectrum, grinding roller bearing, shaft of grinding roller and vibrating sensing
Device is all rigidly connected, so vibrating sensor can collect the rumble spectrum of bearing, it can be monitored on-line, when
There is trickle damage in bearing, its rumble spectrum will unusual fluctuations, vibrating sensor can capture these frequency spectrums, then
Plant maintenance personnel are shown to, maintenance personal according to circumstances can carry out planned maintenance or replacing to bearing.
