Description

A hanger for the side panel of the nacelle cover of a large wind power generating set

technical field

The utility model relates to a hanger for the side plate of the nacelle cover of a large wind power generating set, in particular to a hanger for the side plate of the nacelle cover of the wind power generating set.

Background technique

With the rapid development of wind energy technology and the expansion of market demand in the world, the design of wind turbines tends to be large and diversified. Similarly, the design of nacelle cover will inevitably develop in the direction of large and diverse. The nacelle cover is mostly made of glass fiber reinforced plastics, which is bulky, flexible, and made of special materials. There is no special lifting device. The previous hoisting method is to use slings to hoist the connecting flange of the nacelle cover. During the lifting and installation process, it is easy to overturn due to the inaccurate center of gravity. The operation is difficult, and it is difficult to ensure that it is in a horizontal state during the lifting process, and it is easy to damage the connecting flange of the nacelle cover, which makes the installation of the nacelle cover difficult. The installation of the sling requires multiple people to assist and work at high altitude, which poses a great safety hazard .

Utility model content

In order to change the existing situation, reduce the labor intensity of workers, and improve work efficiency, the utility model breaks the design idea of the traditional spreader and proposes a hanger for the side plate of the nacelle cover of a large-scale wind power generating set.

For solving the shortcoming that prior art exists, the technical scheme that the utility model adopts is as follows:

A hanger for the side panel of the nacelle cover of a large wind power generating set, comprising two cantilever beams and a crossbeam, the cantilever beams are connected to the crossbeam through vertical beams, the cantilever beams are perpendicular to the vertical beams and the crossbeam respectively, And the two cantilever beams are respectively arranged at the two ends of the crossbeam, the top of the crossbeam is provided with lifting lugs, and the two cantilever beams are provided with connecting plates.

The cantilever beam is retractable.

The lifting lugs include three, one lug is set at the center of the beam, and another lug is set on both sides of the center. The three lifting lugs are all porous lifting lugs.

The cantilever beam is connected with the vertical beam through a rectangular device and fastening bolts.

The cantilever beam can move within the rectangular device.

The connecting plate is provided with a plurality of threaded holes.

The beneficial effects of the utility model are:

The connecting plate of the nacelle side panel hanger is connected with the embedded part of the nacelle side panel, and the balance of the nacelle cover can be realized by adjusting the matching position of the sling and the lifting eye hole, and it is connected with the crane through the sling. The position is fixed by the set screw. Due to the slight difference in the structural design of the nacelle cover of different manufacturers, there is also a certain deviation in the size of the embedded parts of the side panel of the nacelle cover. The adjustable suspension beam designed in this way only needs to adjust the length of the cantilever beam and the connection between the suspension strap and the lifting lug during hoisting. position, the nacelle cover can be hoisted horizontally, and the spreader is conveniently installed, saving time and reducing labor intensity. In addition, symmetrical adjustable lifting lugs are provided on the upper beam of the tooling. By finding the center of gravity of the side panel of the nacelle cover and adjusting the lifting point, it can be ensured that the side panel of the nacelle cover is in a horizontal state during hoisting. The cantilever beam is also designed to be telescopic, which is used to adjust the stability of the side plate hoisting process. In this way, the tooling can be hoisted on the left and right sides of the nacelle cover at the same time, and only need to change the position of the lifting lug. The structure is simple, the operation is convenient, the design is stable, the production efficiency is high, and the mass production of wind power generators can be realized.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

The nacelle cover side plate hanger 11 comprises two cantilever beams and a crossbeam 2, the cantilever beam 4 is connected with the crossbeam 2 through the vertical beam 3, and the cantilever beam 4 is perpendicular to the vertical beam 3 and the crossbeam 2 respectively, and the two cantilever beams 4 respectively set at both ends of the beam 2, three lifting lugs are set on the top of the beam 2, the first lifting lug 1 is set at the center of the beam 2, and the second lifting lugs are respectively set on both sides of the center position Ear 7 and the second lug 8, and the three lugs are all porous lugs. Connecting plates 5 are arranged on the two cantilever beams 4 . The cantilever beam 4 is connected to the vertical beam 3 by a rectangular device and fastening bolts. The cantilever beam 4 can move in the rectangular device. The connecting plate 5 is provided with a plurality of threaded holes. The cantilever beam 4 is telescopic.

The multi-direction adjustable hoisting device of the utility model can significantly shorten the hoisting time of the nacelle cover, and adopts a utility model hoisting method to solve the problem that the nacelle cover cannot be hoisted and installed flat.

As shown in Figure 2, the three lifting lugs are symmetrical and adjustable, which can not only meet the differences of nacelle covers 9 designed by different manufacturers, but also realize left and right lifting. Cantilever beam 4 adopts telescopic type, is fixed in position by set screw, also satisfied the difference of different manufacturer's design nacelle cover 9 embedded parts. The specific embodiment is shown in Figure 1: use a crane to connect the lifting lugs through two slings 12 and shackles, one sling 12 is connected to the second lifting lug 7 or the third lifting lug 8 at the end of the beam 2, and the other Suspenders 12 are connected with the first lug 1 in the middle of crossbeam 2, and the position of the two suspenders is adjusted so that the front and rear of the nacelle cover 9 are horizontal, and the center of gravity coincides with the center of gravity line 10 of the side panel of the nacelle cover. The connecting plate 5 is connected with the two embedded parts in the middle of the side plate of the nacelle cover 9, with tightening nuts, and the telescopic length of the cantilever beam 4 is adjusted so that the left and right sides of the nacelle cover 9 are stable, fastened by the set bolts, and then the nacelle cover 9 is lifted When the side panels arrive at the assembly position, the remaining two embedded parts of the front and rear nacelle covers 9 are connected to the complete machine, the tooling is removed, hoisted away, and then the two embedded parts are fastened, thereby completing the hoisting work of the nacelle cover 9 . If the other side nacelle cover 9 needs to be hoisted, then a sling that is connected with the lug at the ends of the beam 2 needs to be changed to the other end symmetrical position, so that the other side can be hoisted.

The hoisting method of the utility model effectively realizes the horizontal hoisting of the nacelle cover, saves the installation time of the sling, eliminates potential safety hazards, reduces labor intensity, and improves production efficiency.
