Abstract
The utility model discloses a novel over-and-under type roll changing machine of a work roll, which relates to the equipment for work roll changing of a cold rolling mill or a temper mill in metallurgical industry. The novel over-and-under type roll changing machine comprises a push-and-pull device and a lifting platform. The push-and-pull device is positioned under a frame at the driving side of a rolling mill, and comprises a roll changing track and a push-and-pull hydraulic cylinder. The lifting platform comprises a lifting track, connecting rods, a lifting hydraulic cylinder, a lifting cover plate and a guiding mechanism. The lifting track is mounted on the lifting cover plate, two groups of connecting rods and the guiding mechanism are mounted under the lifting cover plate, and the connecting rods are driven by the lifting hydraulic cylinder. The guiding mechanism, the connecting rods and the lifting hydraulic cylinder are all fixed on the foundation of a melt pit at the operating side of the rolling mill. The connecting rods are driven to rise by the lifting hydraulic cylinder during roll changing, the push-and-pull hydraulic cylinder drives the roll system of the work roll to move from the roll changing track to the lifting track, and the lifting cover plate drops to the ground after the roll changing is finished. The utility model has the characteristics of novel structure and small occupation area, thereby belonging to a novel over-and-under type roll changing machine of a work roll integrating the economical efficiency and practicability as a whole.
Description
Technical field
Lift work roll changing machine described in the utility model relates to the cold-rolling mill in the metallurgy industry or the work roll changing equipment of planisher.
Background technology
Domestic cold-rolling mill that manufactures and designs and planisher work roll changing all adopt simple and easy roll change or fast roll changing dual mode at present.Its main body is roll changing carriage formula structure, and the transmission of roll changing carriage has hydraulic cylinder transmission, motor-driven and several modes of overhead traveling crane handling.Adopt overhead traveling crane handling mode to be eliminated because of it is backward, time-consuming; And adopt hydraulic pressure or motor-driven, and lay mutually deserved fluid pressure line and cable again, cumbersome and take than large space.Smooth unit generally is arranged in the finished product span centre in workshop, and smooth unit is arranged to mostly: the unit center line is consistent with the traffic direction of overhead traveling crane.Finished product span relative narrower, so the space of unit operation side is also less.As still being parked in the fore side of unit after the work roll changing machine roll change, the working space of unit operation side will become narrow and small like this.At existing problem in the above-mentioned prior art, a kind of novel work roll changing machine of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel lift work roll changing machine of research and design, falls behind equipment complexity, roll change problem such as waste time and energy thereby solve the mill roll device.Lift work roll changing machine described in the utility model is made up of push-pull device at fixed and hoistable platform.Push-pull device at fixed is positioned at the transmission side of milling train, is made up of roll change track and push-and-pull hydraulic cylinder.Hoistable platform is made up of fluctuating orbit, connecting rod, lifting hydraulic cylinder, lifting cover plate, guiding mechanism.Fluctuating orbit is contained on the lifting cover plate, and two groups of connecting rods and guiding mechanism are housed under the lifting cover plate, and connecting rod is driven by lifting hydraulic cylinder; Guiding mechanism, connecting rod and lifting hydraulic cylinder all are fixed on the ground of milling train fore side melt pit.
During lift work roll changing machine roll change described in the utility model, the lifting hydraulic cylinder action, drive link moves, thereby makes the lifting cover plate rise that links to each other with connecting rod.On the lifting cover plate, fluctuating orbit is installed, finally makes the interior roll change track of fluctuating orbit and frame align, even two track upper surfaces are in the same plane.Push-and-pull hydraulic cylinder action this moment is to be pushed out on the fluctuating orbit of fore side by the roll change track with the old working roll in the frame.Hanging away old working roll by overhead traveling crane then is to hang new working roll to be.By the push-and-pull hydraulic cylinder of transmission side new working roll system is drawn in roll change track under the frame by fluctuating orbit again.Be positioned at the lifting hydraulic cylinder drivening rod action of fore side, drive lifting cover plate and fluctuating orbit and drop to ground level place, workshop.So far the roller that changes jobs finishes.
The utility model adopts a kind of brand new, and novel structure compactness, floor space are little.Whole changing machine is arranged in below the operating platform of milling train fore side.The lifting cover plate rises during roll change, and roll change finishes the lifting cover plate and falls, and concordant with the workshop terrace, and the operator can walk, operate milling train in that the lifting cover plate is up.
Description of drawings
The utility model has two accompanying drawings, wherein:
Structural representation when Fig. 1 is the roll change of lift work roll changing machine;
Fig. 2 is a lift work roll changing machine elevating mechanism A-A cutaway view.
Among the figure: 1, push-and-pull hydraulic cylinder 2, roll change track 3, fluctuating orbit 4, connecting rod 5, working roll roller be 6, lifting hydraulic cylinder 7, lifting cover plate 8, guiding mechanism.
Specific embodiment of the utility model shown in Figure 1ly is made up of push-pull device at fixed and hoistable platform as shown in drawings.Push-pull device at fixed is positioned under the transmission side frame of milling train, is made up of roll change track 2 and push-and-pull hydraulic cylinder 1.Hoistable platform is positioned at the fore side of milling train, is made up of fluctuating orbit 3, connecting rod 4, lifting hydraulic cylinder 6, lifting cover plate 7, guiding mechanism 8.Fluctuating orbit 3 is contained on the lifting cover plate 7, and the lifting cover plate is equipped with two groups of connecting rods 4 and guiding mechanism 8 for 7 times, and connecting rod 4 is driven by lifting hydraulic cylinder 6.Guiding mechanism 8, connecting rod 4 and lifting hydraulic cylinder 6 all are fixed on the ground of milling train fore side melt pit.Fig. 2 is a lift work roll changing machine elevating mechanism A-A cutaway view, can see that guiding mechanism 8 and two groups of connecting rods 4 drive lifting cover plate 7 and fluctuating orbit 3.
