Description
Technical field
The invention belongs to metallurgy rolling technical field, relate to a kind of planisher roll change hook structure.
Background technology
In strip production line, in order to shorten roll changing time and enhance productivity, cold mill complex adopts Quick roll-changing device all.Along with development and user's improving constantly capacity requirements of industry control technology, modern hot-leveling unit, also common demands can realize full-automatic fast roll changing.But roller replacing operation is a complicated process, not only needs the cooperation of relevant device, and relates to milling train internal structure.Link up with as an essential tool of roll changing carriage, must being linked into by it, get loose, just can complete the pushing of institute's roll change, pull out.And the hook that gets loose quickly and safely, will gain time for fast roll changing.
In existing structure, after hook is linked into, all need manually close, insert pin, guarantee that hook firmly, then carry out the subsequent operation of roll change; Meanwhile, after completing, need again to extract pin.When position slightly deviation time, pin inserts and extracts and all need the regular hour.And apparatus of the present invention institute use location is backing roll roll change hook, on the downside of cover plate, position is narrow, and it is more difficult that pin is extracted in artificial insertion, during operating cost, and likely causes security incident.
Summary of the invention
The object of this invention is to provide a kind of planisher roll change hook structure, solve in prior art and need manually to press close to operation, artificial insert extract pin difficulty and operating cost time, easily cause the problem of security incident.
The technical solution adopted in the present invention is, a kind of planisher roll change hook structure, comprise the cylinder joint be connected with hydraulic cylinder piston rod, cylinder joint front end is hinged with hook by connecting pin, connecting pin two ends grow outside cylinder joint and are installed with pivoted arm and balancing weight respectively, make hook, connecting pin, pivoted arm, balancing weight relative position constant, group all-in-one-piece linkage; Pivoted arm cantilever termination is provided with roller bearing by pin;
Bearing is welded on the cover plate of permanent plant, bearing axle center hole upper and lower opening is along being respectively arranged with a copper sheathing, depression bar is installed with in the copper sheathing up and down of bearing, depression bar lower end is fixedly connected with roller bearing outer ring, bearing upper surface is welded with steel pipe, steel pipe coaxial sleeve is on depression bar, and depression bar top radial direction is installed with gag lever post, and gag lever post to be sleeved in steel pipe walls in fluting vertically.
Planisher roll change hook structure of the present invention, is further characterized in that:
Depression bar upper end is provided with counterbore homalocephalus, for connecting handle.
The fluting upper-lower position of steel pipe is provided with stopper slot.
Pivoted arm and balancing weight adopt an alignment pin and connecting pin circumference to fix respectively.
The invention has the beneficial effects as follows, on the basis of existing equipment, at former hook place increase linkage, utilize the handle (only using when linking up with and breaking off relations) that is external, by the action of pressing, carrying, hook, loose hook rapidly.Structure is simple, successful, is convenient to control, and is easy to processing and installs, for roll change gains time quickly, and safer and more effective.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the structure of apparatus of the present invention is, comprise the cylinder joint 4 be connected with hydraulic cylinder 5 piston rod, cylinder joint 4 front end is hinged with hook 2 by connecting pin 7, connecting pin 7 two ends grow outside cylinder joint 4 and are installed with pivoted arm 3 and balancing weight 6 respectively, pivoted arm 3 and balancing weight 6 adopt an alignment pin 16 fixing with connecting pin 7 circumference respectively, make hook 2, connecting pin 7, pivoted arm 3, balancing weight 6 relative position constant, group all-in-one-piece linkage; Pivoted arm 3 cantilever termination is provided with roller bearing 9 by pin 8;
Bearing 13 is welded on the cover plate of permanent plant and (does not show cover plate in figure), bearing 13 axle center hole upper and lower opening is along being respectively arranged with a copper sheathing 14, depression bar 11 is installed with in the copper sheathing up and down 14 of bearing 13, depression bar 11 lower end is fixedly connected with roller bearing 9 outer ring, bearing 13 upper surface is welded with steel pipe 12, steel pipe 12 coaxial sleeve is on depression bar 11, depression bar 11 top radial direction is installed with gag lever post 15, gag lever post 15 to be sleeved on steel pipe 12 wall in fluting vertically, the fluting upper-lower position of this steel pipe 12 is provided with stopper slot, when depression bar 11 moves up and down, gag lever post 15 moves up and down in steel pipe 12 gathering sill with depression bar 11, when depression bar 11 is motionless, also by gag lever post 15, to be fixed on bearing on 13,
Depression bar 11 upper end is provided with counterbore homalocephalus, and for the operation of handle 10, handle 10 only uses when linking up with, being enclosed within depression bar 11 head homalocephalus below handle 10, to pressing down/loosing one's grip handle 10, depression bar 11 can being made to pressing down/loose roller bearing 9, drive pivoted arm 3 to rotate, the final hook 2 that drives lifts/falls.
Device of the present invention, former hook basis increases a linkage, eliminates the operation of original artificial latch, completes hook fast, breaks off relations.
The course of work of the present invention sees Fig. 4:
When not carrying out roll change action, balancing weight 6 balances with hook 2, and hook 2 is horizontal.During roll change, hydraulic cylinder 5 piston rod driven forward, to be pushed away hook 2 by cylinder joint 4 and closely links up with 1 place to backing roll; Be arranged on by handle 10 in the counterbore homalocephalus of depression bar 11, handle 10 presses down, and depression bar 11 is pressed in roller bearing 9, by linking up with 2, the connecting rod effect that forms of connecting pin 7, pivoted arm 3, balancing weight 6, hook 2 being lifted, prepares hook; Then hydraulic cylinder 5 piston rod upholds a segment distance again, makes the eave tile of hook 2 be positioned at above backing roll hook 1, at this moment, release handle 10, now depression bar 11 does not stress, under balancing weight 6 acts on, hook 2 falls, and links up with 1 and catches on, then just can carry out the subsequent operation of roll change with backing roll.
Upside down repetition above action during unhook, make backing roll link up with 1 and unclamp with hook 2, then exit, can roll change be completed.
