Utilize the construction method of the supporting and regulating device installing main motor stator of installation in position of main motor stator, job step is following:
(1) utilize driving and lifting beam and steel wire rope in the factory building that main motor stator is winched to the top of installation position earlier, be placed on the supporting steel plate top of the main motor on jack top, and be strained and fixed with bottle gouard moved by hands,
(2) utilize the driving in the factory building that main rotor is hung in the stator, accomplish punching and also support,
(3) start bottle gouard moved by hands, divided stator is repeatedly descended, with jack the main motor stator jacking is risen a bit earlier; Extract partly U shaped steel lip block, utilize jack that main motor stator is slowly descended behind the stroke again, support with U shaped steel lip block; Strain with bottle gouard moved by hands; With the height of a jack stroke of supporting steel pipe cutting, this circulation descends for another example then
(4) when hanging stator, utilize the driving in the factory building that main rotor is sling, and cooperate the circulation of stator to descend and descend; Note keeping the slit between rotor and stator in the decline; After stator and rotor hang to main electric baseboard, adjust, install, utilize bolt.
Device of the present invention device of the present invention adopts common low carbon hot-strip machining to process, and draws materials easily, consumable quantity is little, processing and manufacturing is simple, processing ease, easy to use, can be repeatedly used.
Device solves during installation in position of main motor stator; The driving tonnage can't be with the stator and the rotor integral hoisting difficult problem in place of main motor; Can steel-structure factory building be optimized as far as possible, the tonnage of will driving a vehicle reduces as far as possible, to guarantee the needs of ordinary production and maintenance; And the not specialized designs large-tonnage driving for installing main motor, to save a large amount of investment costs.
Is the present invention in peace steel 3500mm hot rolling, 1780mm hot rolling, Wuhan Iron and Steel Plant 4300mm hot rolling, Jiujiang 3500mm hot rolling? Obtained in the engineering implementing and utilization, all safety, successfully accomplished construction, saved investment cost widely, obtained good economic benefit.
