Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is done to further detailed description:
As shown in Figure 1,2,3, 4, a kind of generator unit stator 4 of the present invention is combined hanging apparatus, adopts existing crane in bridge type 1 technology, and is transformed, utilize hanging apparatus simultaneously, lift the generator unit stator 4 that exceedes crane in bridge type 1 maximum rated hoisting capacity.
Its concrete structure comprises crane in bridge type 1, crane in bridge type 1 comprises two girder 1-2 and auxiliary hook reel, between two girder 1-2 across the crane carriage 1-1 being provided with main hook winch drum and drive motor, between two girder 1-2 also across be provided with can move along girder 1-2 sky beam 2, it beam 2 comprises crossbeam 2-2, between it beam 2 and crane carriage 1-1, be connected with pipe link, they beam 2 bottoms are provided with fixed pulley group 2-1, girder 1-2 lower horizontal is provided with shoulder pole girder 3, shoulder pole girder 3 belows are hung with stator hoisting rope, shoulder pole girder 3 one end, top are provided with outer hanger 3-4 and interior hanger 3-3, on interior hanger 3-3, hang with snatch block, the shoulder pole girder 3 top other ends are provided with leading sheave 3-2 and movable pulley 3-1.Outer hanger 3-4 is suspended on the steel rope being wound on main hook winch drum, as the main assembling device 1-3 that hoists.The steel rope being wound around on auxiliary hook reel is walked around snatch block, leading sheave 3-2, upper fixed pulley group 2-1 and movable pulley 3-1 successively, as secondary jack up unit 1-4.Upper fixed pulley group 2-1 is connected to form side by side by some pulleys.On girder 1-2, be equipped with the slide rail 1-5 coordinating with crane carriage 1-1, day beam 2 bottoms are provided with the piston shoes 2-3 coordinating with slide rail 1-5.
Lifting preparatory process, the suspension hook group that the crane in bridge type of steam turbine building 61 pair is hoisted is put down dismounting, and steel rope is recovered to cylinder.Sky beam 2 is lifted, be positioned between two girder 1-2 of steam turbine building 6 crane in bridge type 1.It beam 2 comprises crossbeam 2-2, and the piston shoes 2-3 of crossbeam 2-2 bottom coordinates with crane carriage 1-1 track, and in injection limiting device.Between it beam 2 and crane carriage 1-1, use respectively two solid drawn pipe firm welding, while ensureing that crane carriage 1-1 moves sky beam 2 can with crane carriage 1-1 synchronizing moving.
