Abstract
The present invention relates to milling train install.A kind of large-sized rolling mills frame bracket rotary hoisting method, it includes double-machine lifting crane shoulder pole girder, shoulder pole girder and rolling-mill housing are connected by steel wire rope and suspender, it is placed on temporary support structure before rolling-mill housing lifting, the bracket utilizing rolling-mill housing during lifting rotates around temporary support structure until rolling-mill housing rotates upright, the installation site then rolling-mill housing being placed on rolling mill base；Temporary support structure is mainly set up by steel billet, steel pipe, flitch and shaped steel and is formed, on the basis of vertical steel billet is placed on changing track for roll, longitudinal steel billet is stacked by some blocks of steel billets on the basis of being laid on vertical steel billet and side, roll change hole, longitudinal steel billet is placed with flitch, has baffle plate around flitch；Laterally steel billet two ends are placed on longitudinal steel billet, and middle part is welded with the steel pipe of support, and sleeper is placed above.Requirement to driving hoisting depth when the present invention greatly reduces lifting, overcomes the deficiency of tradition double-machine lifting crane method, reduces construction cost.
Description
Technical field
The present invention relates to milling train install, particularly relate to the hanging method of large-sized rolling mills frame.
Background technology
The lifting operation of large-sized rolling mills frame is that metallurgical equipment installing area is the finest, most important, one of the operation of most critical, rolling-mill housing is high due to its overall dimensions, weight is big, lifting operation difficulty is big, especially because steel plant's grassroot project reduces scale of investment, controlled investment cost, for lifting capacity and the factory building height restriction of driving a vehicle in production line workshop, there is shop traveller elevating capacity and the problem of lifting altitude deficiency.
Owing to milling train base structure form is complicated, the foundation pits such as roll change hole are smaller in size than rolling-mill housing size, rolling-mill housing is difficult to be placed on lifting in hole, the most conventional employing duplicate rows car lifts to utilize and lifts in the method rotated on ± 0 ground bottom rolling-mill housing, use duplicate rows car to lift and solve the problem that driving elevating capacity is not enough, but owing to using shoulder pole girder, occupy lifting space；Often lead to lifting altitude during rolling-mill housing lifting not enough.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that a kind of large-sized rolling mills frame bracket rotary hoisting method.Requirement to driving hoisting depth when the present invention greatly reduces lifting, overcomes the deficiency of tradition double-machine lifting crane method, and makes full use of field resources, reduce construction cost, expand the range of double-machine lifting crane.
In order to solve above-mentioned technical problem, the present invention is achieved in that hanging method is reserved on a kind of large-sized rolling mills frame basis, and it includes:
Step one, after milling train foundation construction, arranges sheeting caps temporary support mechanism in foundation pit；This supporting mechanism includes:
Being placed on the vertical steel billet on the basis of changing track for roll, top is concordant with side height of foundation；
Being laid on the longitudinal steel billet on the basis of vertical steel billet and side, roll change hole, it is stacked together by one group of steel billet；
Being placed with to place the flitch of rolling-mill housing bracket on longitudinal steel billet, have baffle plate in order to fixing flitch around flitch, longitudinal steel billet front and back end is welded with shaped steel, longitudinal steel billet and vertical between steel billet, shaped steel, baffle plate for being welded to connect；
Laterally steel billet, its two ends are placed on longitudinal steel billet, and middle part, by steel pipe support, is placed above sleeper, is welded to connect between horizontal steel billet and steel pipe；
Step 2, is perpendicular to roll line direction rolling-mill housing and is tiltedly placed on sheeting caps, and the main hook of two drivings jointly lifts a middle part and is provided with the shoulder pole girder rotating gib head, and shoulder pole girder hangs rolling-mill housing by steel wire rope, makes rolling-mill housing rotate upright,
Translate after Zhi Li and be placed on rolling mill base installation site.
The present invention makes full use of the job site resources such as steel scrap base, steel pipe and sets up temporary support structure, and rolling-mill housing is placed on temporary support structure, lifts by crane with the bracket of rolling-mill housing for center of rotation during lifting.Owing to center of rotation is by the bracket changing rolling-mill housing middle and lower part bottom rolling-mill housing into, during rotation bracket with lower part inside temporary support structure, requirement to driving hoisting depth when greatly reducing lifting, overcome the deficiency of tradition double-machine lifting crane method, and make full use of field resources, reduce construction cost, expand the range of double-machine lifting crane.
Accompanying drawing explanation
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is schematic diagram of the present invention；
Fig. 2 is the support node schematic diagram of the present invention；
Fig. 3 is described temporary support structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3: two drivings lift shoulder pole girder 2 jointly by main hook 1, connected by steel wire rope and suspender 3 between shoulder pole girder 2 and rolling-mill housing 4, it is placed on sheeting caps temporary support structure 5 before rolling-mill housing 4 lifting, the bracket 6 utilizing rolling-mill housing during lifting rotates around temporary support structure 5 until rolling-mill housing rotates upright, the installation site then rolling-mill housing 3 being placed on rolling mill base.
Main being set up by steel billet, steel pipe, flitch and shaped steel of sheeting caps temporary support structure 5 forms, on the basis of vertical steel billet 9 is placed on changing track for roll, top is the most concordant with basis, side 15, longitudinal steel billet 7 is stacked by one group of steel billet and is laid on vertical steel billet 9 and basis, side 15, roll change hole, it is placed with flitch 8 on longitudinal steel billet 7, baffle plate 12 is had in order to fixing flitch around flitch 8, rolling-mill housing bracket is placed on flitch 8, shaped steel 11 in order to prevent longitudinal steel billet 7 play, longitudinal steel billet 7 and vertical between steel billet 9, shaped steel 11, baffle plate 12 for being welded to connect.Laterally steel billet 14 two ends are placed on longitudinal steel billet 7, and middle part is supported by steel pipe 10, and sleeper 13 is placed above, and is used for placing rolling-mill housing and protecting rolling-mill housing machined surface.Laterally for being welded to connect between steel billet 14 and steel pipe 10.
