Abstract

The invention relates to relocation of equipment, in particular to a disassembling method of a mill housing during relocation. The disassembling method of the mill housing during relocation comprises the following steps: mill housing disassembling: after disassembling double nuts of foundation bolts, slowly hoisting a hook of a crane at a first gear, observing a tonnage display, and stopping hoisting when a numerical value reaches 90% of the tonnage of the mill housing; after separating the mill housing from a mill base by 5-10 mm by using a hydraulic jack under the mill housing, continuing hoisting the crane, enabling a trolley to move to the position of a foundation of a roll changing pit after the mill housing is completely separated from the mill base by a distance longer than the height of a working roll changing foundation; mill housing falling: after hoisting the mill housing to the position of a tool of the roll changing pit, rotating at an angle of 90 degrees, enabling the inner side of the mill housing to face downwards, slowly returning the hook and enabling the outer side of the bottom of the mill housing to fall on the tool; returning the hook of the crane at the first gear in a jogging manner, meanwhile traveling slowly, enabling the mill housing to be inclined through deviation of the center of gravity generated by dislocation of the center of gravity of the mill housing and a supporting point, and ensuring a steel wire rope hook to be perpendicular until the mill housing falls; and after falling, horizontally hoisting the mill housing to a temporary storage position, storing and packaging well. Disassembling and relocation of the mill housing are implemented.

Description

Method for dismounting during mill housing resettlement
Technical field
The equipment that the present invention relates to is removed, and particularly relates to the dismounting of metallurgical equipment.
Background technology
Along with heavy industry is outwards shifted from down town, some still have the milling equipment of the very big surplus value protectiveness removal to recycle, and are greatly saved assets.At present, the domestic precedent that there is no large-scale strange land human relocation project, the particularly resettlement of large-sized rolling mills equipment not yet occur.
Mill housing, weight is big, and volume is also big, and general maintenance does not move it.2005, production line, because of the enlargement of the factory buildings, was planned by Hunan steel again, so that move mill housing, but only need to move in Factory Building, utilized driving in Factory Building, adopted double-machine lifting crane and special handling suspender to carry easily.And the application research is strange land resettlement, spatial extent reaches hundreds and thousands of kilometer, it is clear that experience above cannot adopt.
As previously described, because equipment uses the time to reach far away projected life, equipment can also continue to use, and therefore, needs properly equipment to be protected in unloading process.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that the method for dismounting during resettlement of a kind of mill housing.The present invention has filled up the technological gap of dismounting in the resettlement of mill housing strange land.
In order to solve above-mentioned technical problem, the method for dismounting during resettlement of a kind of mill housing, it includes:
Memorial archway is removed: after removing foundation bolt double nut, and driving slowly hooks up with one grade of gear, observes tonnage display constantly, when numerical value reaches memorial archway tonnage 90%, stops hoisting;After the lower section of memorial archway uses hydraulic jack that with rolling mill base, memorial archway is departed from 5~10mm, continue the driving that hoists, until after completely disengaging from the rolling mill base height beyond work roll changing basis, walking dolly cheats base bits to roll change;
Memorial archway fell: after memorial archway winches to frock position, roll change hole, and 90-degree rotation, it is ensured that set level inside rear memorial archway downward slowly returns hook and drops in frock by the outside bottom memorial archway;Drive a vehicle and return hook slowly walking simultaneously with one grade of gear crawl, utilize memorial archway center of gravity and strong point dislocation to produce centre-of gravity shift, make memorial archway tilt, and ensure that steel wire rope hook is vertical, until memorial archway fell;Memorial archway is the flat temporary storage point that winches to after falling, and carries out and deposit packaging.
The mill housing still having use value is removed by the present invention, can ensure memorial archway not impaired keep flat, for subsequent transportation, filled up the technological gap of dismounting in the resettlement of mill housing strange land.
Detailed description of the invention
A kind of method for dismounting during mill housing resettlement, it includes:
Memorial archway is removed: after removing foundation bolt double nut, and driving slowly hooks up with one grade of gear, observes tonnage display constantly, when numerical value reaches memorial archway tonnage 90%, stops hoisting;After the lower section of memorial archway uses hydraulic jack that with rolling mill base, memorial archway is departed from 5~10mm, continue the driving that hoists, until after completely disengaging from the rolling mill base height beyond work roll changing basis, walking dolly cheats base bits to roll change;
Memorial archway fell: after memorial archway winches to frock position, roll change hole, and 90-degree rotation, it is ensured that set level inside rear memorial archway downward slowly returns hook and drops in frock by the outside bottom memorial archway;Drive a vehicle and return hook slowly walking simultaneously with one grade of gear crawl, utilize memorial archway center of gravity and strong point dislocation to produce centre-of gravity shift, make memorial archway tilt, and ensure that steel wire rope hook is vertical, until memorial archway fell;Memorial archway is the flat temporary storage point that winches to after falling, and carries out and deposit packaging.
