Abstract
The utility model relates to a vibration protection system belonging to the field of production automation. The vibration protection system of a main transmission mechanism of a COREX vertical mill comprises a millstone (6) of a COREX vertical mill, a grinding roller (3) on the millstone (6) and a main transmission mechanism which is connected with the millstone (6) and pushes the millstone (6) to rotate, wherein the main transmission mechanism comprises a mill main speed reducer (2) and a mill main motor (1); and the main speed reducer (2) is mounted under the millstone (6) and the mill main motor (1) connected with the mill main speed reducer (2). The vibration protection system of the main transmission mechanism of the COREX vertical mill is characterized in that a vibration sensor (7) is mounted at one side of the main transmission mechanism and connected with a vibration controller (4) which is connected with a hydraulic controller of a hydraulic station (5); and the hydraulic controller controls a hydraulic pull rod (8) fixedly connected with the grinding roller (3) to move up and down. The utility model eliminates the damage of abnormal vibration to main transmission equipment by directly controlling a vibration source, ensures the continuity of the production and prolongs the service life of equipment.
Description
Technical field
The utility model relates to a kind of vibrations protection system, relates in particular to a kind of vibrations protection system that is used to protect the main drive gear of COREX Vertical Mill.
Background technology
At present, in service at Vertical Mill, if during the phenomenon of the unusual vibrations of grinding roller,, can all produce very big damage to other equipment or even the Vertical Mill of main transmission equipment and drive apparatus one side if main transmission equipment is not protected.And now common way is that the mode taking main transmission equipment is initiatively shut down realizes the purpose protected.But adopt this method to have some bad consequences, if exactly when needs are proceeded to produce or need be produced once more, all must restart main transmission equipment, and restart main transmission equipment as grinding machine master motor or grinding machine main gear reducer, need very long time first, if second this high-power main motor is turn-offed continually and restarts, shortened the service life of equipment greatly, three shutoffs are restarted to be needed to increase energy consumption, has also incured loss through delay the time in the production.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of COREX Vertical Mill main drive gear vibrations protection system, solves prior art and it is initiatively shut down and the delay production that causes, shortens service life of equipment and the big defective of energy consumption.
Technical scheme
A kind of COREX Vertical Mill main drive gear vibrations protection system; the mill 6 that comprises the COREX Vertical Mill; grinding roller 3 on the mill 6; the main drive gear of promotion mill 6 rotations that mill 6 connects; described main drive gear comprises grinding machine main gear reducer 2 that is installed under the mill 6 and the grinding machine master motor 1 that is connected with main gear reducer 2; it is characterized in that: shock sensor 7 is installed in the main drive gear side; shock sensor 7 connects vibrations controller 4; described vibrations controller 4 is connected with the hydraulic controller of Hydraulic Station 5, the moving up and down of the hydraulic pressure draw-bar 8 that hydraulic controller control and grinding roller 3 are fixedly linked.
Described vibrations controller 4 adopts the Centralized Controller of DCS dcs, is provided with active station in the main drive gear side.
Described Centralized Controller includes the vibrations parameter setting module, sensor values comparison module and controlled quentity controlled variable output module.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of COREX Vertical Mill main drive gear vibrations protection system; the mill 6 that comprises the COREX Vertical Mill; grinding roller 3 on the mill 6; the main drive gear of promotion mill 6 rotations that mill 6 connects; described main drive gear comprises grinding machine main gear reducer 2 that is installed under the mill 6 and the grinding machine master motor 1 that is connected with main gear reducer 2; in the main drive gear side shock sensor 7 is installed; shock sensor 7 connects vibrations controller 4; described vibrations controller 4 is connected with the hydraulic controller of Hydraulic Station 5, the moving up and down of the hydraulic pressure draw-bar 8 that hydraulic controller control and grinding roller 3 are fixedly linked.
Described vibrations controller 4 adopts the Centralized Controller of DCS dcs, is provided with active station in the main drive gear side.
Described Centralized Controller includes the vibrations parameter setting module, sensor values comparison module and controlled quentity controlled variable output module.Select in the shock value scope that should bear according to the equipment work that each equipment vendors provides the setting that makes the shock value that protection system starts, and each equipment all is controlled in this vibrations scope.
Described shock sensor 7 is installed in grinding machine main gear reducer 2 and grinding machine master motor 1 connecting path one side.
The central controlled operation principle of this programme utilization DCS; configure the shock value that this protection system starts by active station; the value that feeds back to the DCS Centralized Controller when the shock sensor 7 that is installed in the main transmission side has surpassed this value; this protection system comes into operation; the DCS Centralized Controller gives the hydraulic controller signal of on-the-spot Hydraulic Station 5; hydraulic controller starts hydraulic pressure draw-bar 8; hydraulic pressure draw-bar 8 upwards action lifts grinding roller 3 automatically; make grinding roller 3 leave mill 6 surfaces; eliminated and caused the excessive main cause of main transmission equipment vibrations; the grinding machine master motor 1 and the grinding machine main gear reducer 2 of main drive gear side have in time been protected; grinding roller 3, mill 6 and other are subjected to the equipment of the relevant main drive gear of its vibration influence.
