Abstract
The invention relates to a roll changing device for a rolling mill working roll. A roll changing frame body is placed on the ground where an operation side of a rolling mill is located, an oil cylinder frame is installed on the middle portion of the rear end of the roll changing frame body, and an oil cylinder is installed on an oil cylinder supporting seat; the roll changing frame body is provided with a working roll changing rail, frame rollers advance and retreat along the working roll changing rail, the frame rollers are installed at two ends of a support frame body, the support frame body is connected with an oil cylinder rod head of a roll changing oil cylinder, a pulling hanging hook is installed at the front end of the support frame body, and a pushing baffle is welded to the front end of the support frame body; a support is installed on a working roll bearing seat and connected with a support connecting shaft; by means of the drive of the oil cylinder which is installed at the rear end of the roll changing frame body, the roll changing rail arranged at the front end of the roll changing frame body is connected with the working roll changing rail arranged inside the rolling mill in a butt joint mode, the front end of the pulling oil cylinder is connected with the support frame, when the pulling hanging hook is in contact with the support connecting shaft which is arranged on the working roll bearing seat, the hanging hook falls down under the action of gravity and then hooks the connecting shaft, and a roll is dragged out driven by the oil cylinder. The structure is simple, the operation is convenient, the space is saved, and the roll changing efficiency is high.
Description
Technical field
The present invention relates to mill milling production technical field, be specifically related to a kind of operation roll of mill changing rig.
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 object of the present invention is to provide a kind of operation roll of mill changing rig, 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 present invention takes is:
A kind of operation roll of mill changing rig, 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 invention 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 invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in the figure, a kind of operation roll of mill changing rig, 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 invention 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.
