Abstract
The invention relates to an on-line adjustment device for a bottom roll of a rolling mill. The on-line adjustment device adopts controllable hydraulic oil cylinders, wherein the controllable hydraulic oil cylinders are arranged in a roll exchange vehicle; the bottom roll is arranged at the upper part of the roll exchange vehicle; and the lower part of the roll exchange vehicle is sequentially connected with a bracket, a hoist cylinder and a rack lower transverse beam. According to the on-line adjustment device, the structure is simple, the usage is convenient, and the installation and the maintenance are convenient; and a plurality of controllable hydraulic oil cylinders are arranged in the roll exchange vehicle, so that a bottom roll bearing seat slides in a window of a rack arch, and the bottom roll is jacked up by means of the controllable hydraulic oil cylinders, and a base plate is added. The on-line adjustment is simpler, more convenient and reliable, and the adjustment time and the labor intensity are greatly saved.
Description
Technical field
The present invention relates to a kind of auxiliary conditioning unit of heavy section steel rolling equipment, relate in particular to a kind of milling train bottom roll at line adjusting device.
Background technology
At present, existing changing rig is used for roll is hauled out in framework window, again ready roll is pushed in the frame, for satisfying technology to the requirement of bottom roll height, after roller diameter changed, the height of bottom roll will be adjusted, and traditional method is to add backing plate after top and bottom rolls is hauled out frame under bearing block, be so-called off-line adjustment, this mode relatively wastes time and energy.
Summary of the invention
The present invention provides a kind of simple in structure, easy to use, milling train bottom roll of increasing work efficiency at line adjusting device in order to overcome the above problems.
Technical scheme of the present invention is: described at line adjusting device for can regulate hydraulic jack, can regulate hydraulic jack and be arranged in the roll changing carriage, described roll changing carriage top is bottom roll, the bottom connects carriage, hoist cylinder and frame sill successively.
The described hydraulic jack of regulating is symmetricly set on the inner both sides of roll changing carriage.
The present invention is simple in structure, easy to use, convenient for installation and maintenance, in roll changing carriage, arrange a plurality of hydraulic jacks of regulating, allow the bottom roll bearing block in the framework memorial archway window, slide, utilization can be regulated and add backing plate after hydraulic jack holds up bottom roll, this online adjustment is easier to be reliable, saves adjustment time and labour intensity greatly.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is bottom roll among the figure, the 2nd, and roll changing carriage, the 3rd, can regulate hydraulic jack, the 4th, carriage, the 5th, hoist cylinder, the 6th, frame sill.
