The hoisting equipment and hoisting method of the wind power generating set according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a hoisting device according to an embodiment of the present invention. The hoisting device can be used for combined hoisting of the nacelle and generator of a wind power generating set, and ensures that the generator does not deform during the hoisting process, thereby achieving hoisting efficiency and compatibility Improve the lifting quality at the same time.

As shown in Figures 1 to 3, the hoisting equipment is used for hoisting the combination of the generator 80 and the nacelle 70, the nacelle 70 is equipped with a base 71, and the base 71 is provided with lifting lugs 72, including the suspension beam 10 , the first hoisting part 20 and the second hoisting part 30 .

On the tower, the hoisting process has the best hoisting efficiency. Since the connecting plate 31 is connected to the flange surface of the generator 80, during the hoisting process, the flange surface with higher rigidity will not be deformed, so that the generator 80 will not be damaged, thereby avoiding the need to use the motor installed on the generator 80. The lifting lugs on the outside of the rotor make the generator prone to deformation when the generator 80 is hoisted.

Specifically, the suspension beam 10 can be a straight beam with a first end 11 and a second end 12, and the first hoisting part 20 and the second hoisting part 30 can be respectively arranged on the first end 11 and the second end of the suspension beam 10. The end 12 is used to connect the nacelle 70 and the generator 80 respectively, and carry out combined hoisting to the combination of the nacelle 70 and the generator 80 , therefore, the length of the suspension beam 10 corresponds to the combined length of the nacelle 70 and the generator 80 .

The number of the first slings 21 corresponds to the number of the hanging ears 72 on the base 71 , and a plurality of first slings 21 are respectively connected to the corresponding hanging ears 72 . Moreover, the length of the first sling 21 is determined according to the size of the overall structure of the nacelle 70 (including the nacelle cover and the base 71 , etc.), and the specific location of the lifting lugs, so as to facilitate the hoisting of the nacelle 70 by the first hoisting part 20 .

In addition, the technical solution of the present invention does not limit the connection method between the second sling 33 and the connecting plate 31. In other embodiments, the second sling 33 can also be connected to the connecting plate 31 in other ways, for example, the second sling 33 The stable connection between the second suspender 33 and the connecting plate 31 can be achieved by directly passing through the through hole 35 and connecting with the connecting plate 31 , or connecting with the connecting plate 31 through a suspension ring.

Preferably, the number of connecting plates 31 is at least two (two in the figure), and the number of second suspenders 33 corresponds to the number of connecting plates 31 .

The connecting plates 31 are used to connect to the flange surface of the generator 80 to facilitate safe hoisting of the generator 80, so the number of connecting plates 31 is determined according to the overall weight of the generator. In the actual application scene, since the weight of the generator 80 is not overweight, and the area of its flange surface is limited, two connecting plates 31 are arranged on both sides of the center of the flange surface, which is enough to stably and reliably install the generator 80.

Wherein, the structure of the first lifting hole 13 is similar to that of the above-mentioned second lifting hole 41 , which will not be repeated here. The first shackle 22 is connected to the other end of the third sling 23 , and a plurality of first slings 21 are all connected to the first shackle 22 for realizing the connection with the first end 11 of the suspension beam 10 . The connection mode of multiple first slings 21 and the first shackle 22 is preferably passed through the first shackle 22 and folded in half, which is used to increase the bearing capacity of the first sling 21, so that the first hoisting part 20 can hoist the cabin more stably .

Preferably, the hoisting device further includes a counterweight 50, which is detachably disposed on the first end 11 of the suspension beam 10, and is used to balance the suspension beam 10 after the hoisting device is hoisted.

The specific position where the counterweight 50 is arranged on the suspension beam 10 can be determined according to the respective weights of the nacelle 70 and the generator 80 . Since the weight of the nacelle 70 is less than the weight of the generator 80, after the hoisting device lifts the combination of the nacelle 70 and the generator 80, the second end 12 of the suspension beam 10 is inclined downward, and the counterweight 50 is placed on the The first end 11 of the beam 10 can keep the suspension beam 10 balanced, so that the hoisting device can stably hoist the combination of the nacelle 70 and the generator 80 .

In addition, the counterweight 50 can be disassembled from the suspension beam 10, so that the number of counterweights 50 can be adjusted, and then the weight of the counterweight 50 arranged on the suspension beam 10 can be adjusted to accurately adjust the suspension beam 10. of balance.

For another example, the sling (comprising the first sling 21, the second sling 33, and the third sling 23) has the advantages of high load-carrying capacity and light weight, which reduces the overall weight of the hoisting device, so that the hoisting device can be easily carried, which can Consists of special-shaped slings in the prior art. In addition, the sling in this solution can also be replaced by other devices, such as sling chains or slings.
