The specific embodiment

The distortion combination base model of combined sling has three kinds: first kind of array mode as shown in Figure 1 and Figure 2, is used for generator unit stator and turns to.It is different when in place that most generator unit stators transportations cause after the steam turbine building its direction, need horizontally rotate 90 °, unloads and turn to needs so combined sling at first must satisfy generator unit stator.Little hanging beam 5 times hangs the crane hook of using 3 by hanging hook steel rope 4, and suspension hook 3 times is hung generator unit stator 1 by turning to jack line, so just can realize that generator unit stator unloads, turns to.Little hanging beam 5 tops hang on the hanger with jack line by lifting, and hanger and lower supporting rod 8, U-shaped hanger link together by bearing pin, and concrete connection mode is seen Fig. 9, Figure 10.The U-shaped hanger is connected arm-tie bottom by bearing pin, and the top of arm-tie links together by the two ends of bearing pin and last strut, the lower end of Combined pulley group, and concrete connection mode is seen Figure 11, Figure 12.The Combined pulley group hangs on the dolly by hoist rope.Second kind of array mode is used for generator unit stator lifting, this array mode remove remove little hanging beam 5, suspension hook 3, hanging hook with the steel rope 4 and first kind identical, lift and directly hang generator unit stator 1 with the jack line lower end.The third array mode, be used for the lifting of 300MW and following generator unit stator, this array mode is compared with second kind of combination, two dollies, two cover hoist ropes, two Combined pulley groups have only been kept, removed and all gone up struts, whole long arm-ties, three short arm-ties are hung by bearing pin by each Combined pulley group bottom, and the U-shaped hanger is hung by bearing pin by weak point arm-tie bottom, sees Fig. 5, Fig. 6.Connection mode and second kind of combination below the U-shaped hanger are identical.Because the Combined pulley group of this combined sling can be combined as 6 wheels or 8 wheels (referring to Figure 11, Figure 12, remove 4 distance covers at two Combined pulley group upper pin two ends, two otic placodes can endwisely slip on Combined pulley group lower bearing pin, can adorn two pulleys on each Combined pulley group upper pin in the middle of two otic placodes like this, the Combined pulley group is just taken turns from 6 and is become 8 and take turns), last strut, lower supporting rod all adopts flange, bolt segmentation combination, arm-tie also makes up by bearing pin, can be equipped with the arm-tie of different length, so this combined sling is easy to and different manufacturers, the driving of different tonnages is complementary.

For the 600MW-1000MW generator set, in every driving, need to increase by one and overlap the dolly that hoists (this method is identical with existing utilization driving lifting generator unit stator), two drivings are the totally 4 covers dolly that hoists, and every cover hoists and wears around a Combined pulley group (removing the former main suspension hook that hoists of driving) with hoist rope under the dolly.Use first kind of combination to realize that generator unit stator turns to, use second kind of combination to realize the generator unit stator hoisted in position.

For 300MW and following generator set, two covers that two drivings of general using the carry dolly that hoists can satisfy generator unit stator lifting needs, so adopt the third combination to realize the generator unit stator hoisted in position.Need turn to as generator unit stator, on the basis of the third combination, in the lifting with the jack line lower end carry additionally little hanging beam 5, hanging hook just can realize that with steel rope 4, suspension hook 3 generator unit stator turns to, the bottom section of hang and first kind of combination is identical.Indivedual 300MW and following generator unit stator design weight are bigger, and two cover lifting mechanisms can also adopt the hanging method of 600MW-1000MW generator unit stator noted earlier can not satisfy the lifting needs time.
