Abstract
The invention relates to a construction method for replacing a roll bending and shifting hydraulic cylinder frame of a plate rolling mill, which is characterized by comprising the steps of manufacturing a support raft, arranging a lead screw connecting plate on the support raft, rotating the roll bending and shifting hydraulic cylinder frame out from a memorial archway by utilizing a rotating lead screw, finally putting on the support raft, pulling out the support raft by using a working roll replacing hydraulic cylinder and completing the replacement of the roll bending and shifting hydraulic cylinder frame. The construction method disclosed by the invention has the advantages that the roll bending and shifting hydraulic cylinder frame can be rapidly replaced; the safety is higher; and the construction time is shorter.
Description
Technical field
The present invention relates to a kind of construction method of more board-changing type roller mill roll bending and shifting hydraulic cylinder framework, belong to metallurgical machinery equipment installation field.
Background technology
Wide and heavy plate mill roller roll shifting hydraulic cylinder mainly is comprised of equipment such as roller roll shifting hydraulic cylinder framework, roller roll shifting hydraulic cylinder, hydraulic locking cylinder, locking nuts.Its Main Function is to utilize the fixing also position of leveling working roll of roller roll shifting hydraulic cylinder, thereby milling train can be run well.Roller roll shifting hydraulic cylinder framework is directly to be installed on the mill housing by locating piece, and uses bolted.It is bearing the weight of working roll self in the milling train production process and the vibration force that occurs in running, be the important component part of milling equipment.
The finishing mill of the Wide and Thick Slab continuous rolling production line of the sheet-steel rolling mill of iron and steel enterprise in process of production fore side outlet roller roll shifting hydraulic cylinder framework damages easily, the cut deal both sides of producing in this case differ serious, directly affect production and sales, in order further to guarantee market, the sheet-steel rolling mill must change roller roll shifting hydraulic cylinder framework.General replacing method is: after roller roll shifting hydraulic cylinder block is removed, unclamp the connecting bolt between roller roll shifting hydraulic cylinder framework and the memorial archway, then in frame, hang two 10t jacks, take turns the framework of changing commanders with the 10t jack after dismounting is finished at last and remove, returning dress at last.The cycle of finishing dismounting and installing of this process is longer, needs more manpower and materials.
Summary of the invention
The objective of the invention is in order to solve the technical problem of roller roll shifting hydraulic cylinder framework overall pulling down, sliding and replacing, provide a kind of simple to operate, safe, quick, and can reduce the construction method of the more board-changing type roller mill roll bending and shifting hydraulic cylinder framework of operating expenses.
The objective of the invention is to realize in the following ways:
At first on-the-spot actual measurement roller mill roll bending and shifting hydraulic cylinder framework bottom surface is to the spacing between the working roll track, and the size of roller roll shifting hydraulic cylinder framework own, and confirms the position of centre of gravity of framework; Make a holder row according to measurement result, holder row be made of with the vertical leading screw connecting plate that is located on the base platform base platform, it is the supporting leg on plane that there is the bottom surface base platform both sides, have screw on the leading screw connecting plate, be furnished with leading screw in the screw, be provided with gib head in the center of the sidewall of base platform; Utilize the work roll changing hydraulic cylinder that the row of holder is pushed in the frame, then adjusting screw allows holder row contact fully with roller roll shifting hydraulic cylinder framework; Leading screw on the holder row is connected with roller roll shifting hydraulic cylinder framework, then utilize leading screw that roller roll shifting hydraulic cylinder framework steadily is moved out on the holder row in frame, gib head on utilizing at last the work roll changing hydraulic cylinder and holder being arranged is connected pulls out the row of holder in frame, utilize at last overhead traveling crane that roller roll shifting hydraulic cylinder framework integral body is hung oneself away from holder row and be put into assigned address; New roller roll shifting hydraulic cylinder framework is placed on the holder row, and by leading screw itself and holder row are connected and fixed, adopt the step opposite with dismounting roller roll shifting hydraulic cylinder framework that new roller roll shifting hydraulic cylinder frame is installed and go back, the overall pulling down of finishing roller roll shifting hydraulic cylinder framework more changes jobs.
Advantage of the present invention is: adopt the construction method of the present invention can quick-replaceable roller roll shifting hydraulic cylinder framework, and security is higher, the used time of constructing be also shorter.

The specific embodiment
Embodiment
The finishing mill of Baogang sheet-steel rolling mill 3800mm Wide and Thick Slab continuous rolling production line finds that in process of production fore side outlet roller roll shifting hydraulic cylinder framework damages, moreover the cut deal both sides of producing in this case differ serious, directly affect production and sales, in order to guarantee that further market, sheet-steel rolling mill determine to change roller roll shifting hydraulic cylinder framework.
The construction method that adopts is carried out according to the following steps:
1, on-the-spot actual measurement roller mill roll bending and shifting hydraulic cylinder framework bottom surface is to the spacing between the working roll track, and the size of roller roll shifting hydraulic cylinder framework own, and confirms the position of centre of gravity of framework;
2, make a holder row according to measurement result, holder row be made of with the vertical leading screw connecting plate 4 that is located on the base platform base platform 1, it is the supporting leg 2 on plane that there is the bottom surface base platform both sides, have screw 6 on the leading screw connecting plate 4, be furnished with rotating threaded shaft 5 in the screw, be provided with gib head 3 in the center of the sidewall of base platform;
3, utilize the work roll changing hydraulic cylinder that the row of holder is pushed in the frame, then adjust rotating threaded shaft, allow holder row contact fully with roller roll shifting hydraulic cylinder framework 7, and so that roller roll shifting hydraulic cylinder framework 7 centers of gravity on the row's of holder center line;
4, the rotating threaded shaft on will the row of holder is connected with roller roll shifting hydraulic cylinder framework, then utilize rotating threaded shaft that roller roll shifting hydraulic cylinder framework steadily is moved out on the holder row in frame, gib head on utilizing at last the work roll changing hydraulic cylinder and holder being arranged is connected pulls out the row of holder in frame, utilize at last overhead traveling crane that roller roll shifting hydraulic cylinder framework integral body is hung oneself away from holder row and be put into assigned address;
5, new roller roll shifting hydraulic cylinder framework is placed on the holder row, and by leading screw itself and holder row are connected and fixed, adopt the step opposite with dismounting roller roll shifting hydraulic cylinder framework that new roller roll shifting hydraulic cylinder frame is installed and go back, the overall pulling down of finishing roller roll shifting hydraulic cylinder framework more changes jobs.
All are normal in test running behind the roller roll shifting hydraulic cylinder framework integral replacing.Can be described as safe, short-term, the high-quality replacing task of finishing roller roll shifting hydraulic cylinder framework, solved a great problem.We have only finished the replacing task of roller roll shifting hydraulic cylinder framework this engineering with 1 day time, finished in 2 days in advance than plan.
