Description
Technical Field
The utility model relates to a cold rolling mill technical field specifically is a cold rolling mill group supporting roller bearing temperature automatic monitoring feedback system.
Background
The supporting roll of cold rolling unit generally changes the cycle longer, if take place wearing and tearing difficult discovery, if wearing and tearing appear can lead to whole supporting roll to scrap owing to not in time discover and continue long-time operation, cause great loss, mainly rely on operative employee's experience to judge at present, obviously the operational reliability is not enough.
Disclosure of Invention
The utility model aims at providing a cold rolling unit supporting roller bearing temperature automatic monitoring feedback system is provided in order to solve the experience judgement that current backing roll operation mainly relies on the operative employee, the not enough problem of reliability.
The utility model has the following concrete scheme: the utility model provides a cold rolling mill group supporting roller bearing temperature automatic monitoring feedback system, includes the bearing frame at supporting roller both ends, and the bearing frame outer end is equipped with the closing cap, is equipped with the inspection hole on the closing cap, and the interpolation of inspection hole is equipped with detachable temperature sensor, automatic monitoring feedback system still includes temperature inspection appearance, PLC cabinet, router and supervisory control computer, temperature inspection appearance one end is connected temperature sensor, and the PLC cabinet is connected to the other end, and the PLC cabinet sends the supervisory control computer with received data signal through the router, the supervisory control computer still is connected with unit major control system, and major control system forces the roll system rotational speed to descend and lock the unit when the temperature exceedes the setting value.
Detection hole department is equipped with the quick connector who matches with temperature sensor, and quick connector includes the socket, is equipped with the jack that communicates with the through-hole in the middle of the socket, temperature sensor include with the fixed cover that the socket matches, correspond in the middle of the fixed cover the fixed PT100 type thermocouple that is equipped with of jack department, PT100 type thermocouple insert in order to realize detecting the temperature in the closing cap in the jack.
The temperature and the historical temperature curve that record are shown in real time on the display of supervisory control computer.
The utility model discloses the theory of operation as follows: the PT100 type thermocouple real-time measuring bearing seat temperature data is transmitted to a temperature polling instrument, the temperature polling instrument transmits temperature analog quantity data to a PLC cabinet, the PLC cabinet converts data signals into Ethernet and transmits the Ethernet to a monitoring computer through a router, a display picture of the monitoring computer displays a temperature value and a historical temperature curve in real time, the monitoring computer is connected with a unit main control system, and when the temperature exceeds a set value, the unit automatically reduces the rotating speed of a roller system and locks the unit.
Compared with the prior art, the utility model has the following advantages: 1. the temperature is automatically monitored, and the running state of the unit is convenient to judge; 2. when the temperature is too high, the unit automatically takes measures to avoid loss; 3. the temperature sensor is installed on the sealing cover through the quick connector, and is convenient to disassemble and assemble when the roll shaft is replaced.
