Description
Technical field
The utility model relates to mill milling production technical field, is specifically related to a kind of operation roll of mill roll-changing equipment.
Background technology
In rolling operation line, because working roll needs frequent replacing, the whether easy to use of workroll change just seems very important, directly affects the production efficiency of milling train.The workroll change of milling train in the past, need to lay changing track for roll at the fore side of milling train, by roll change cart forward-reverse, roll change cart is provided with tractor again and passes in and out milling train to pull working roll, this device often floor space is large, and tonnage is large, operates also more complicated, and often have the region roll change cart of personnel activity to retreat at fore side, not very safe.Changing rig complex structure, once go wrong, maintenance neither be very convenient.
Summary of the invention
In order to overcome above-mentioned prior art shortcoming, the purpose of this utility model is to provide a kind of operation roll of mill roll-changing equipment, and structure is simple, saves and takes up an area space, and operating maintenance is convenient, and safe and reliable, roll change efficiency is high.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of operation roll of mill roll-changing equipment, comprise roll change support body 2, roll change support body 2 is placed on the ground of milling train fore side, cylinder support 11 is arranged on the middle part, rear end of roll change support body 2, cylinder support 11 is provided with oil cylinder 10, roll change support body 2 is provided with work roll changing track 1, support roller 6 is retreated along work roll changing track 1, support roller 6 is arranged on the two ends of supporting frame 9, supporting frame 9 connects with the cylinder rod head of roll change oil cylinder 10, traction hook 4 is by connecting with bearing pin 5 front end being arranged on supporting frame 9, and traction hook 4 can overturn, the front end of supporting frame 9 is welded with and promotes baffle plate 8, support 3 is arranged on working roll bearing block by bolt, support 3 connects with support coupling spindle 7.
Advantage of the present utility model is: structure is simple, saves and takes up an area space, and operating maintenance is convenient, and safe and reliable, roll change efficiency is high.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in the figure, a kind of operation roll of mill roll-changing equipment, comprises work roll changing track 1, roll change support body 2, support 3, traction hook 4, bearing pin 5, support roller 6, and support coupling spindle 7, promotes baffle plate 8, supporting frame 9, oil cylinder 10 and cylinder support 11, roll change support body 2 is placed on the ground of milling train fore side, cylinder support 11 is arranged on the middle part, rear end of roll change support body 2, cylinder support 11 is provided with oil cylinder 10, roll change support body 2 is provided with work roll changing track 1, support roller 6 is retreated along work roll changing track 1, support roller 6 is arranged on the two ends of supporting frame 9, supporting frame 9 connects with the cylinder rod head of roll change oil cylinder 10, roll change oil cylinder 10 is fixed on cylinder support 11, traction hook 4 is by connecting with bearing pin 5 front end being arranged on supporting frame 9, and traction hook 4 can overturn, the front end of supporting frame 9 is welded with and promotes baffle plate 8, support 3 is arranged on working roll bearing block by bolt, support 3 connects with support coupling spindle 7.
Operation principle of the present utility model is:
During work roll changing, first roll change support body 2 is placed to the fixing roll change position of milling train fore side, work roll changing track 1 on roll change support body 2 and the working roll orbital docking in milling train, roll change oil cylinder 10 promotes supporting frame 9 and moves, automatically lift after support coupling spindle 7 is encountered on the outer inclined-plane of hook being arranged on the traction hook 4 of supporting frame 9 front end, draw hook 4 under gravity to fall, catch on coupling spindle 7, under the effect of oil cylinder 10, the working roll pull-out in milling train, hoisting traveling crane working roll of slinging is placed to suitable position, then the working roll of milled is placed on the work roll changing track 1 of roll change support body 2, oil cylinder 10 promotes supporting frame 9, the support roller 6 at two ends is walked along changing track for roll 1, traction hook 4 manually lifts, turn over, the promotion baffle plate 8 being arranged on supporting frame 9 front end pushes the work forward the support coupling spindle 7 of roll bearing seat front end under the effect of oil cylinder 10, working roll enters the operating position of milling train along work roll changing track 1.Then hoisting traveling crane hangs away roll change support body entirety, does not take the space of fore side.So far, a complete work roll changing process operation completes.Convenient and swift, shorten roll changing time, improve Rolling Production efficiency.
