Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
Fig. 1-3 schematically show a wind turbine hanger according to an embodiment of the present invention. As shown in fig. 1-3, the wind power generator lifting appliance comprises a balancing weight 1, a lifting beam main body 2, a lifting lug 3, a rigging 4 and a turnbuckle 5.
In order to avoid the structural interference with the split structure, the whole hanging beam main body 2 is of a non-completely symmetrical structure and comprises two triangular hanging beams, and therefore the caused gravity center shift is balanced by the balancing weight 1. Because the whole hanging beam main body 2 is in a non-completely symmetrical structure, the whole wind driven generator hanger is in a non-completely symmetrical structure so as to avoid interference. The two triangular suspension beams constituting the suspension beam main body 2 are a first suspension beam 21 and a second suspension beam 22, respectively. One side common to the first hanging beam 21 and the second hanging beam 22 is a first hanging beam rod 23. The first suspension beam 21 further includes a second suspension beam rod 211 and a second straight-side rod 212. The first suspension beam 21 is provided therein with a first cross bar 213. One end of the first cross bar 213 is connected to the first girder rod 23, and the other end of the first cross bar 213 is connected to the second straight-side rod 212. The first cross bar 213 is disposed parallel to the second hanger bar 211. The second suspension beam 22 further includes a third suspension beam rod 221 and a third straight-side rod 222. A second cross bar 223 is arranged in the second hanging beam 22, one end of the second cross bar 223 is connected with the first hanging beam rod 23, and the other end of the second cross bar 223 is connected with the third straight-side rod 222. The second cross bar 223 is disposed in parallel with the third girder rod 221. The lower end surfaces of the first hanging beam rod 23, the second hanging beam rod 211 and the third hanging beam rod 221 are respectively provided with a plurality of lifting lugs 3 so as to adapt to split structures of different specifications. The first boom beam 23 is provided with a spreader 7 so that the entire spreader can be lifted. The upper end surfaces of the first hanging beam rod 23, the second hanging beam rod 211 and the third hanging beam rod 221 are provided with a plurality of threaded holes 6 for fixing the balancing weight 1 and adjusting the center of gravity. The balancing weight 1 is fixed on the lifting appliance 3 by bolts, and can be freely disassembled or even installed in a plurality of ways according to requirements. The rigging 4 is connected on the lug 3, and the design of rigging 4 middle part has basket of flowers bolt 5 to adjust rigging 4 length, guarantees the levelness.
Firstly, designing the gravity center and the position of a lifting lug of a split structure according to the split structure, determining the proper lifting position and the position of the lifting lug on a lifting beam main body 2, installing a rigging 4, adjusting the position of a balancing weight 1 on the lifting beam main body 2 to enable the lifting beam main body 2 to be kept horizontal when being lifted independently, connecting the rigging 4 and the lifting lug 3 of the split structure, lifting, and then adjusting a turnbuckle 5 and the balancing weight 1 to enable the split structure to be in a horizontal state. Different from the traditional lifting appliance, the triangle of the lifting appliance of the wind driven generator is respectively provided with three balancing weights 1 which are fixed on the lifting beam by bolts and can adjust the position so as to adjust the gravity center. A plurality of lifting lugs 3 are respectively arranged below three beams of the hanging beam main body 2, different positions can be selected when the hanging beam main body is matched with split structures with different specifications, and the lifting lugs 3 connected with the rigging 4 on the hanging beam main body 2 are also matched with the hanging beam main body in a plurality of positions. The rigging 4 is added with a turn buckle 5 design for levelness adjustment.
The above description is only some embodiments of the present invention, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept, and these modifications and improvements all belong to the protection scope of the present invention.
