Abstract
The utility model belongs to auxiliary tools for overhauling a rough rolling working roll of a rolling mill unit in a rolling mill plant, and particularly relates to a guide and guard auxiliary lifting tool of the rough rolling working roll of a rolling mill. The guide and guard auxiliary lifting tool is characterized in that a supporting plate is formed by rectangular steel plates, notches formed in the face of one side of the supporting plate form evenly-distributed stepped end faces, and a control rod is vertically and fixedly connected to one face of the supporting plate. The guide and guard auxiliary lifting tool is simple and practical in structure, a guide and guard plate can be lifted to a roll replacing position by uplifting force of the working roll, then, the working roll can be conveniently replaced, roll replacing time can be shortened, and roll replacing efficiency can be improved.
Description
Technical field
The utility model belongs to the auxiliary lifting instrument of aid, the particularly guide and guard of a kind of milling train rough rolling working roll of steel rolling mill's maintenance milling train group rough rolling working roll.
Background technology
The rough rolling working roll guide and guards mainly drives cylinder to form by swing type foreplate, foreplate.The swing type foreplate is divided into top working roll foreplate and bottom working roll foreplate, and upper foreplate is mainly to scrape off roll cooling water and be bonded at the iron scale on top roll, the effect upwarped with steel that prevents is also arranged, and can be with the upper roller system synchronization lifting simultaneously.Lower guide and guard backplate is to prevent from being with curved under steel head and heap steel, and upper and lower foreplate, all by air cylinder driven, is installed nylon sheet on upper and lower foreplate directly to contact with working roll, after wearing and tearing, changes during maintenance; The guide and guard backplate also can be collected roll cooling water and derive from side, avoids water directly to drop on steel plate.Lower roll is that cooling water collector, high-pressure water descaling collector are mounted with on memorial archway.
Because the strength that drives the foreplate cylinder is less than normal, when the rotating shaft of foreplate is piled up due to iron oxide or during the other reasons jam, foreplate turns to the roll change position by the rolling position and has certain difficulty.Especially descend foreplate, it also will overcome own wt in the process of rotating.
When foreplate can't reach the roll change position, the meeting of rough rolling working roll lower roll transmission side bearing block and foreplate are interfered, and hinder roll change buggy working roll is pulled out in frame.So often roughing zone roll changing time, extend because lower foreplate is not in place.
Summary of the invention
The purpose of this utility model is to provide the guide and guard of a kind of milling train rough rolling working roll to assist the lifting instrument, and it is simple and practical, can be by the make progress strength of lifting of working roll, foreplate is raised to the roll change position, change easily working roll, shorten roll changing time, improve roll change efficiency.
The purpose of this utility model is achieved in that the guide and guard of a kind of milling train rough rolling working roll assist the lifting instrument, the gripper shoe formed by rectangular steel plates, the breach arranged on the side plate face of gripper shoe forms uniform ladder you face, vertical affixed control stick on the plate face of gripper shoe.
Using method of the present utility model
The first step, instantly during the foreplate jam, first order ladder platform of the present utility model is inserted in foreplate and working roll gap, utilize aid to make progress the strength of lifting by the foreplate lifting that makes progress by working roll.
Second step, after working roll is raised to a high position, the second level of the present utility model ladder platform is inserted in foreplate and working roll gap, utilize aid to make progress the strength of lifting by the foreplate lifting that makes progress by working roll.
The 3rd step, after working roll is raised to a high position, third level ladder platform of the present utility model is inserted in foreplate and working roll gap, utilize aid, by the make progress strength of lifting of working roll, foreplate upwards is raised to the roll change position.Roll change buggy is pulled out working roll easily in frame, is changed in time working roll.
The utility model is simple and practical, has realized, by the make progress strength of lifting of working roll, foreplate is raised to the roll change position, has realized changing easily working roll, has shortened roll changing time, has improved roll change efficiency.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is main TV structure schematic diagram of the present utility model, the right TV structure schematic diagram that Fig. 2 is Fig. 1.
The specific embodiment
The lifting instrument is assisted in the guide and guard of a kind of milling train rough rolling working roll, as shown in Figure 1 and Figure 2, the gripper shoe 1 consisted of rectangular steel plates, the breach arranged on the side plate face of gripper shoe 1 forms uniform ladder you face, vertical affixed control stick 2 on the plate face of gripper shoe 1.The thickness of gripper shoe 1 is 20 ㎜, and the height of each ladder platform of gripper shoe 1 ladder you face is 100 ㎜, and width is 100 ㎜.The length of control stick 2 is 2000 ㎜, and the steel pipe that control stick 2 is 20 ㎜ by diameter forms.The progression of the uniform ladder you of gripper shoe 1 face is 3 grades.
