Abstract

The utility model discloses a roll bending and shifting maintenance tool of a hot-rolling finishing mill group. The roll bending and shifting maintenance tool is characterized by comprising a maintenance cart, a support, a push-pull rod cart and a hook head, wherein the maintenance cart comprises a plate-shaped frame and wheels positioned under the frame, and the wheels are matched with a work roll changing track; the support comprises a plate-shaped upper supporting seats and supporting legs positioned under the upper supporting seats, and the lower parts of the supporting legs are fixedly arranged on a supporting base plate; the supporting base plate is fixedly connected with the upper surface of the frame of the maintenance cart through a bolt; the push-pull rod cart comprises a cart body and idler wheels positioned on the lower surface of the cart body, and the cart body is horizontally connected with the maintenance cart through a push-pull rod; the hook head takes the shape of U with two joint ends; and the joint ends of the hook head are fixedly arranged at one side of the push-pull rod cart which is far away from the maintenance cart, through the bolts. The roll bending and shifting maintenance tool has the advantages of increasing the maintenance speed, reducing the labor strength and ensuring the normal operation of equipment.

Description

The curved roll shifting maintenance of a kind of hot fine rolling unit frock
Technical field
The utility model relates to the curved roll shifting of a kind of hot fine rolling unit, the curved roll shifting maintenance of especially a kind of hot fine rolling unit frock.
Background technology
In steel rolling mill; The curved roll shifting of hot fine rolling unit is a kind of equipment that is used to control belt plate shape, glacing flatness and convexity; It is installed on mill housing window middle part inner surface, mainly by roller cylinder, roll shifting cylinder, holder, move connecing of seat, base, working roll locking and connecting device and transmission side and spool hold tightly etc. and to form.It is a kind of very ripe existing equipment.
When the curved roll shifting of existing hot fine rolling unit is worked; Its base and a mobile seat joint face, roller cylinder end face flange, roll shifting cylinder end face flange; The working roll locking cylinder; Problem, the especially base of hydraulic fluid leak usually can take place and move seat joint face leakage of oil problem the most outstanding in positions such as working roll connection cylinder, and hydraulic oil just need overhaul after revealing.Because curved roll shifting structural design of hot fine rolling unit and installation site, when causing fault to take place, the dimension inspection can't be in time, fast processing, and the online leakage of oil processing time of single is on average about 3 hours; Had a strong impact on carrying out in order that hot rolling is produced.
Making a concrete analysis of its reason, during the online treatment fault, is because space for maintenance is narrow, no inspection platform, and driving can't directly be lifted by crane, and is prone to secondary failure takes place, so cause the online treatment time longer.
So any design one cover makes things convenient for the frock of the curved roll shifting maintenance of hot fine rolling unit, improves inspection speed, reduces labour intensity, assurance equipment runs well, and becomes those skilled in the art that technical problem to be solved is arranged.
The utility model content
To the deficiency of prior art, the utility model technical problem to be solved is how a kind of raising inspection speed to be provided, reduction labour intensity, the curved roll shifting maintenance of the hot fine rolling unit that assurance equipment runs well frock.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
The curved roll shifting maintenance of a kind of hot fine rolling unit frock, its characteristics are, comprise
Inspection trolley, said inspection trolley comprise the vehicle frame and the wheel that is positioned at the vehicle frame below, wheel and work roll changing Orbit Matching of plate shape;
Support, said support comprise the upper bracket and the feet that is positioned at the upper bracket below of plate shape, and the feet below is fixed on to be supported on the backing plate, supports that backing plate is connected inspection trolley vehicle frame upper surface through bolt;
Pull bar dolly, said pull bar dolly comprise car body and the roller that is positioned at the car body lower surface, and car body links to each other with the inspection trolley level through pull bar;
Gib head, said gib head are " U " font with two tip sides, and the tip side of gib head is through being bolted on the pull bar dolly away from inspection trolley one side.
In this frock, inspection trolley is the cast steel workpiece, is main inspection platform, is used for the transhipment and the dismounting of equipment.Support is mainly used in to change in the curved roll shifting and moves seat, and the adjustment of its level height can realize through above the support backing plate of support, installing pad additional.Can also set up alignment pin, alignment pin is mainly used in the equipment transport process, prevents the equipment displacement.When wherein pull bar and pull bar dolly are mainly used in and change the roll shifting of finishing mill transmission lateral bending and move; Restriction because of roll change oil cylinder range; Inspection trolley can not directly arrive transmission side maintenance position; Therefore between inspection trolley and gib head, install pull bar additional to increase displacement, the pull bar dolly mainly plays connection, support and stabilization.Gib head is mainly used in being connected of maintenance frock and roll change oil cylinder.In whole maintenance process, the mobile transhipment with equipment of frock mainly realizes through the roll change oil cylinder.
When using this turnaround of unit,, at first remove the displacement transducer and the end face connecting plate of curved roll shifting device if need inspection operation lateral bending roll shifting device.Before maintenance, gib head is connected with bolt with inspection trolley, and winches to the maintenance scene; Be placed on the work roll changing track, the push-and-pull cylinder stretches out, and hooks gib head; Promote dolly and proceed to curved roll shifting place; And, remove the location-plate and the base oil pipe between seat that move up and down of curved roll shifting device with the upper surface of upper bracket in the roller cylinder cylinder head alignment inspection trolley (can groove and locating piece be set with the convenient alignment pin location of adopting) at the upper bracket upper surface, will descend to move with bottle gouard moved by hands and be pulled on the inspection trolley; The withdrawal of push-and-pull cylinder drives directly lifting appliance place of inspection trolley to driving.Will the be old mobile seat of driving is left under order, and will newly move and winch on the dolly, the align upper surface of upper bracket in the inspection trolley of roller cylinder cylinder head; The push-and-pull cylinder stretches out; Promote dolly and proceed to the maintenance position, will move the seat top to the installation position, accomplish the installation of moving seat down with jack.Go up moving the seat dismounting and installing needs mounting bracket on plane on the inspection trolley, and the level of support and highly available pad are adjusted, and the plane is parallel with the holder upper surface on support, go up the dismounting of moving seat and installation steps with following mobile identical.
In sum, the utility model possesses the raising inspection speed, reduces labour intensity, the advantage that assurance equipment runs well.This special tooling is many to the curved roll shifting plant failure point of hot fine rolling unit, and the cause that occurrence frequency is high according to actual condition, device structure and installation site, designs.Adopt this frock, can be by equipment degradation trend, inaction interval, periodical repair model, the off-line assembling realizes regularly this device integral body being carried out quick preventative maintenance.
