Compared to the spreader 1 of the first embodiment, the spreader 5 according to the present invention is connected to the lower surface of the flange of the generator moving shaft 10 through the upper surface of the main body portion 51, and each of the connecting portions 52 may be in contact with the side surface of the flange of the generator moving shaft 10. In an actual hoisting process, the main body 51 may be located on a lower surface of the flange of the generator moving shaft 10, and a connecting member such as a bolt may be inserted into the plurality of connecting holes H1 from bottom to top to be connected to the flange of the generator moving shaft 10.

In addition, because including oblong hole and circular port in a plurality of connecting holes H1 to the position and the interval of adapting unit such as adjustable connecting bolt make when according to the utility model discloses a when hoist 5 is applied to the generator moving axis 10 that has different flanges, can be according to the hole interval of different flanges and the hookup location of adapting unit such as adjusting bolt, thereby can ensure that the hoist is general.

As shown in fig. 5, in actual hoisting, a pair of lifting tools 1 of the hoisting assembly according to the present invention can be connected to the upper surface of the flange of the generator moving shaft 10, respectively, and hoisted in the height direction under the action of the lifting hook 6. A pair of hangers 1 may be respectively disposed on both sides of the upper surface of the flange of the generator moving shaft 10 so that the fixing portions 2 of the hangers 1 are connected to the generator 9. The lifting eye of the lifting appliance 1 is connected with a shackle 8, and the shackle 8 is connected with a lifting belt 7.

During the actual hoisting, the hoisting force is transmitted to the sling 7 by the hook 6, so that the shackle 8 is gradually moved upwards, in which case the hoisting part 3 of the spreader 1 is rotatable relative to the fixed part 2, and the hoisting part 3 is gradually moved upwards in a rotation trajectory around the axis of rotation, eventually reaching the highest position. As shown in fig. 5, the diameter of the generator moving shaft 10 gradually decreases from the lower portion toward the upper portion. Therefore, when the highest position of the hoist 3 is located at a portion of the generator moving shaft 10 near the lower portion, the position of the attached shackle 8 is also located at a portion of the generator moving shaft 10 near the lower portion, and since the diameter of the portion of the generator moving shaft 10 is relatively large, the hoist 3 or the shackle 8 may interfere with the generator moving shaft 10 to press the generator moving shaft 10 to be damaged.

In the hoist 1 according to the present invention, as described above, the thickness of the connecting portion 22 may be greater than the thickness of the main body portion 21 in the height direction, and thus, a predetermined distance may be provided between the axis of the rotation shaft and the central surface of the main body portion 21 in the height direction. In this case, the lifting part 3 may be located at a portion closer to the upper portion of the generator moving shaft 10 with respect to the fixing part 2 so that the rotation locus of the lifting part 3 may be moved upward as a whole, and the highest position of the lifting part 3 may be closer to the portion of the upper portion of the generator moving shaft 10 (as shown in fig. 5, the portion of the generator moving shaft 10 having a smaller diameter), which may reduce the occurrence of damage to the generator moving shaft 10 due to the lifting part 3 or the shackle 8 being pressed by the generator moving shaft 10 during the lifting process.

Alternatively, in the hanger 1 according to the present invention, the thickness of the connecting portion 22 may also be formed not more than the thickness of the main body portion 21 in the height direction. In this case, the connection portion 22 may be disposed to have an inclination angle with the main body portion 21 such that the axis of the rotation shaft has a predetermined distance from the central surface of the main body portion 21 in the height direction, thereby preventing damage from occurring due to the lifting portion 3 or the shackle 8 pressing the generator moving shaft 10 during lifting, as described above. However, the shape and structure of the connecting portion 22 according to the present invention are not limited thereto, and may be changed as needed as long as it is satisfied that the axis of the rotation shaft has a predetermined distance from the central surface of the main body portion 21 in the height direction.

In addition, according to the utility model discloses a hoist of hoist and mount subassembly can not only include a pair ofly (two) when using, and can include a plurality ofly according to actual need, and a plurality of hoists set up uniformly on the flange of generator moving axis, can guarantee to hoist the in-process with load evenly distributed on every hoist.

In the above, the part of using waiting to hoist has carried out schematic description to the hoist and mount subassembly for aerogenerator as an example, however, according to the utility model discloses a hoist and mount subassembly not only can be used to hoist and mount aerogenerator, still can hoist and mount other parts such as axle, cabin base or the similar part in other fields according to actual need.

As described above, according to the utility model discloses a hoist and mount subassembly includes a pair of hoist, this hoist simple structure, simple to operate, can improve the work efficiency of hoist and mount operation.
