Description
Technical field
The present invention relates to cold rolling technology field, more particularly, relate to a kind of cold rolling unit jockey pulley changing rig.
Background technology
" S " type jockey pulley enters, exports the stable of tension force for ensureing milling train, is one of equipment important in cold rolling unit.Jockey pulley need be made regular check on, safeguards and change.While changing jockey pulley, conventionally use changing rig drawing tension roller by fixing track turnover jockey pulley frame.Jockey pulley is drive roll, up-down rollers respectively by one approximately the alternating-current variable frequency motor of 250～350KW drive.Two drive motors stagger up and down, are arranged in transmission side.Because jockey pulley needs periodic replacement, examination and maintenance, in order to operate facility, the changing rig of jockey pulley is arranged in fore side.
Traditional jockey pulley roll changing carriage and jockey pulley use same walking track.Roll change hydraulic cylinder is arranged on ground (absolute altitude is ± 0mm), and roll change hydraulic cylinder weighs the general specification that adopts according to unit width specifications, jockey pulley diameter and roller: diameter is 125～200mm, and stroke is 3500～4000mm.The changing track for roll of jockey pulley changing rig, hydraulic cylinder, hydraulic cylinder erection support etc. are approximately higher than ground 300～500mm.On changing rig, lay roll change cover plate if consider, equipment absolute altitude is higher.Cold rolling unit fore side is the place that crew operated, safeguarded unit, and ground elevation is ± 0mm.In process of production, crew travels to and fro between uncoiler and coiling machine frequently, all needs to stride across into, outlet jockey pulley changing rig.Traditional jockey pulley changing rig that enters, exports has caused very large obstacle to unit operation personnel, and the normal operating that has not only affected unit is safeguarded, also Operation and Maintenance personnel's safety is brought to potential threat.Meanwhile, traditional jockey pulley changing device is tumbled in order to prevent roll change buggy, adopts screw thread to be directly connected (non-ball pivot mode) between roll change buggy and roll change hydraulic cylinder.Which needs the depth of parallelism and the axiality of strict guarantee hydraulic cylinder body and changing track for roll, roll change buggy, has increased the installation difficulty of changing rig, is easy in use cause hydraulic cylinder " to suppress cylinder ", occurs the equipment fault such as leakage of oil or piston rod bending.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of absolute altitude that makes roll change hydraulic cylinder to drop to below ground, got rid of unit staff production, safeguard the cold rolling unit jockey pulley changing rig of obstacle.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of cold rolling unit jockey pulley changing rig, comprise roll change buggy, roll change hydraulic cylinder, jockey pulley walking track, roll change buggy translation described in roll change Driven by Hydraulic Cylinder, described roll change buggy pulls jockey pulley along described jockey pulley walking rail moving, also comprise trolley track, described trolley track comprises two " U " shape tracks that opening is oppositely arranged, described roll change buggy comprises car body and be arranged on the walking slide block on car body, and described walking slide block is positioned at " U " shape track; Described jockey pulley walking track and trolley track are fixed on track bearing, and the height of described trolley track and roll change hydraulic cylinder is lower than described jockey pulley walking track; Described roll change buggy is provided with the first gib head, and described jockey pulley is provided with the second gib head, and described the first gib head and the second gib head lock; Described the first gib head is connected by the first bearing pin with car body, and described roll change gib head swings up and down around described the first bearing pin, and described roll change gib head is also connected with counterweight, and the contact-making surface of described the first gib head and the second gib head is inclined-plane.
In such scheme, described car body is provided with side slider guide, and described side slider guide is positioned at the inner side of walking slide block.
In such scheme, between described roll change buggy and roll change hydraulic cylinder, be connected by ball pivot.
In such scheme, described roll change buggy is provided with the second bearing pin, and the piston rod of described roll change hydraulic cylinder connects described ball pivot, and described ball pivot connects described the second bearing pin.
In such scheme, described jockey pulley walking track is than the high 200～300mm of described trolley track, and described roll change hydraulic cylinder center absolute altitude is than the low 300～500mm of jockey pulley walking track.
In such scheme, described roll change hydraulic cylinder top is provided with cover plate.
Implement cold rolling unit jockey pulley changing rig of the present invention, there is following beneficial effect:
1, roll change hydraulic cylinder rodless cavity oil-feed piston rod stretches out, and drives roll change buggy to advance, and roll change buggy slides in " U " shape track of walking combined track by walking slide block.When roll change buggy runs near jockey pulley frame, the first gib head on roll change buggy is bowed, and in the time that roll change buggy runs to front extreme position, the counterweight on the first gib head comes back gib head, the mutual interlock of the second gib head on the first gib head and jockey pulley.Roll change hydraulic cylinder rod chamber oil-feed piston rod is retracted, roll change buggy hauls jockey pulley by the first gib head and departs from frame, jockey pulley slides on the jockey pulley walking track on upper strata, roll change buggy slides on the trolley track of lower floor, change after jockey pulley, roll change buggy moves ahead by roll change Hydraulic Cylinder jockey pulley, packs frame into.
2, roll change buggy uses different walking tracks from jockey pulley, trolley track is lower than changing track for roll, therefore roll change hydraulic cylinder of the present invention center absolute altitude is lower than jockey pulley walking track, be placed in below ground (absolute altitude is ± 0mm), when operation, attendant travel to and fro between between uncoiler and coiling machine, do not need to stride across into, outlet jockey pulley roll change hydraulic cylinder, ensure the unimpeded of unit operation platform, improve the efficiency of unit operation, maintenance, reduced crew and frequently climbed step and cause injured potential safety hazard.
3, the carriage walking track left and right sides all adopts " U " shape track, prevents from tumbling before and after roll change buggy.
