Description
Technical field
A kind of the present invention relates to cold rolling technology field, more particularly, it relates to cold mill complex jockey pulley changing rig.
Background technology
" S " type jockey pulley is used for ensureing that milling train enters, exports stablizing of tension force, is one of important equipment in cold mill complex.
Jockey pulley need to be made regular check on, safeguards and change.When changing jockey pulley, changing rig drawing tension roller is usually used and passes through fixation
Track passes in and out tension force roller frame.Jockey pulley is drive roll, and up-down rollers are respectively by the alternating-current variable frequency motor of an about 250～350KW
Drive.Two motors stagger up and down, are arranged in transmission side.Because jockey pulley needs periodic replacement, examination and maintenance, in order to grasp
Facilitate, 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 in ground (mark
A height of ± 0mm) on, roll change hydraulic cylinder typically adopts specification according to unit width specifications, tension force roller diameter and roller weight：A diameter of
125～200mm, stroke is 3500～4000mm.The changing track for roll of jockey pulley changing rig, hydraulic cylinder, hydraulic cylinder erection support
Etc. being approximately higher than ground 300～500mm.If considering to lay roll change cover plate on changing rig, equipment absolute altitude is higher.Cold mill complex is grasped
It is crew's operation, safeguards the place of unit, ground elevation is ± 0mm as side.In process of production, crew is frequently
Travel to and fro between uncoiler and coiling machine, be both needed to across entering, export jockey pulley changing rig.Traditional enters, exports jockey pulley roll change dress
Put and cause very big obstacle to unit operation personnel, the normal operating that not only have impact on unit is safeguarded, also to Operation and Maintenance people
The safety of member brings potential threat.Meanwhile, traditional jockey pulley changing device in order to prevent roll change buggy from tumbling, roll change buggy with change
Between roller hydraulic cylinder, (non-ball pivot mode) is directly connected to using screw thread.Which needs strict guarantee hydraulic cylinder body and roll change rail
Road, the depth of parallelism of roll change buggy and axiality, increased the installation difficulty of changing rig, easily lead to hydraulic cylinder when using
, the equipment fault such as oil leak or piston rod bending in " suppressing cylinder ".
Content of the invention
The technical problem to be solved in the present invention is, provides a kind of absolute altitude making roll change hydraulic cylinder to drop to below ground, row
Except unit staff production, safeguard the cold mill complex 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 mill complex jockey pulley roll change dress
Put, including roll change buggy, roll change hydraulic cylinder, jockey pulley walking track, described in roll change Driven by Hydraulic Cylinder, roll change buggy translation, described
Roll change buggy pulls jockey pulley to move along described jockey pulley walking track, also includes trolley track, described trolley track includes out
Two " u "-shaped tracks that mouth is oppositely arranged, described roll change buggy includes car body and the walking slide block being arranged on car body, described row
Walk slide block to be located in " u "-shaped track；On described jockey pulley walking track and the fixing in rail bearing of trolley track, described little track
The height of road and roll change hydraulic cylinder is less than described jockey pulley walking track；Described roll change buggy is provided with the first gib head, described

Bearing pin connects, and described first gib head swings up and down around described first bearing pin, and described first gib head is also connected with counterweight, and described first
The contact surface of 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 located at the inner side of walking slide block.
In such scheme, it is connected by ball pivot between described roll change buggy and roll change hydraulic cylinder.
In such scheme, described roll change buggy is provided with the second bearing pin, and the piston rod connection of described roll change hydraulic cylinder is described
Ball pivot, described ball pivot connects described second bearing pin.
In such scheme, described jockey pulley walking track 200～300mm higher than described trolley track, described roll change hydraulic pressure
Cylinder center absolute altitude 300～500mm lower than jockey pulley walking track.
In such scheme, above described roll change hydraulic cylinder, it is provided with cover plate.
Implement the cold mill complex jockey pulley changing rig of the present invention, have the advantages that：
1st, roll change hydraulic cylinder rodless cavity oil-feed piston rod stretches out, and drives roll change buggy to advance, roll change buggy is slided by walking
Block is in the " u "-shaped gliding in tracks of walking combined track.When roll change buggy runs to close tension force roller frame, on roll change buggy
First gib head is bowed, and when roll change buggy runs to front extreme position, the counterweight on the first gib head makes gib head come back, the first gib head
It is mutually twisted with the second gib head on jockey pulley.Roll change hydraulic cylinder rod chamber oil-feed piston rod is retracted, and roll change buggy passes through first
Gib head hauls jockey pulley and departs from frame, and jockey pulley slides on the jockey pulley walking track on upper strata, and roll change buggy is little in lower floor
Slide on track road, after having changed jockey pulley, roll change buggy is moved ahead by roll change Hydraulic Cylinder jockey pulley, load frame.
2nd, roll change buggy uses different walking tracks from jockey pulley, and trolley track is less than changing track for roll, the therefore present invention
Roll change hydraulic cylinder center absolute altitude is lower than jockey pulley walking track, is placed in ground (absolute altitude is ± 0mm) below, operation, attendant
When travelling to and fro between uncoiler and coiling machine, it is not required to across entering, export jockey pulley roll change hydraulic cylinder it is ensured that unit operation platform
Unimpeded, improve unit operation, the efficiency safeguarded, reduce crew and frequently climb step and lead to injured safety hidden
Suffer from.
3rd, all using " u "-shaped track, tumble before and after preventing roll change buggy in the carriage walking track left and right sides.
