Description

5 OBJECT OF THE INVENTION

The present invention is part of the technical field of devices for storage and / or transport of wind turbine parts. More specifically, a nacelle roof support device is described.

BACKGROUND OF THE INVENTION

Wind turbines are equipment for obtaining wind energy. These wind turbines comprise a wind turbine tower, a nacelle installed in the

15 top end of the tower and at least one shovel.

The nacelle of the wind turbines comprises at least one roof, which is a piece arranged in its upper section. When these pieces are already manufactured it is necessary to store them until their later union with the rest of the pieces that make up the nacelle.

20 Likewise, transport is sometimes necessary to the place of assembly or installation.

Some solutions for the storage and transport of different wind turbine elements are known from the state of the art. Specifically, some are known

25 solutions for storage and transport of roofs of nacelle.

For example, document CN204076235 is known which describes a support device for nacelle roofs comprising at least two supports arranged along the longitudinal direction of each roof. Each support comprises a base, two

30 posts and at least one limiting lever on each post. Said lever is connected to the corresponding post slidingly in the direction of the nacelle roof thickness. The minimum distance at which the limit lever is positioned with respect to the base is greater than the thickness of the roof of the nacelle.

35 C204078608 is also known which describes a nacelle roof storage device comprising a plurality of supports, each

one of them with two posts respectively arranged such that in the final position each of them is on one side of the nacelle roof. The height of each of the posts is greater than the thickness of the nacelle roof to be stored.

5 Similarly, document CN203532172 describes a device for transport of nacelle bases comprising a lifting base on which they are arranged support components. Some capacity is allowed on the device of lifting movement and lateral movement.

10 DESCRIPTION OF THE INVENTION

The present invention proposes a nacelle roof support device that is intended to store and transport said nacelle roofs. The device is mobile so it can move within the storage area itself or at the plant

15 assembly

The device allows storing a plurality of nacelle roofs stacked on each other but avoiding contact between them. This saves storage space, because it is vertical storage, and at the same time guarantees

20 that do not suffer blows.

The proposed support device comprises at least a first structure and a second structure. The first structure is configured to allow the support of a nacelle roof. The second structure, which is mobile with respect to the first structure,

25 allows the support of at least one additional nacelle roof.

One of the most important features of the device of the present invention is that the second structure comprises mobile support arms for supporting nacelle ceilings. It preferably comprises two support arms for each roof of

30 nacelle that you want to store and / or transport in it. The support arms are arranged, two by two, in different rows, separated from each other a sufficient distance so that between couples there is more height than that corresponding to the thickness of the nacelle roofs to be stored.

35 The fact that the arms are movable allows them to be placed in a first position supporting nacelle ceilings and in a second passage position free of roofs of

Nacelle Each arm can move independently of the rest of the arms. When the arms are arranged in the first position, they allow to support a nacelle roof. When the arms are arranged in the second position, they facilitate the placement of nacelle ceilings in lower support arms or in the first structure.

5 Thanks to the fact that the support arms can be placed in the second position, it is facilitated much the placement of nacelle roofs in lower arms or in the first structure. Likewise, blows from the roofs of nacelle in the device are avoided during The storage operation.

10 The device can also be foldable. In this case the second structure is folded over the first structure and the device can be stored occupying a smaller space when it is not being used.

It is also an object of the present invention a support assembly comprising at least four support devices as described. Preferably, the support devices are arranged two by two and are joined together by stringers.

The support set allows nacelle roofs to be stored more securely and

20 that the nacelle roof is supported on more points distributed along its surface, than in cases where it is supported by a single support device. That is, when a nacelle roof is supported on a support device, it is supported at two points, each corresponding to a support arm, while in the case of a support assembly with, for example, four devices, he

25 nacelle roof is supported by eight points (two support points for each device).

PREFERRED EMBODIMENT OF THE INVENTION

Examples of embodiments of the invention are described below with the help of Figures 1 to 9.

In figure 1 the nacelle roof support device (1) of the present invention can be observed. In said figure a support assembly (2) is seen comprising a plurality of nacelle roof support devices (1) (6). In this case the set is configured to support four nacelle roofs (6) and

5 comprises six support devices (1). You can see in this figure how to take advantage of the space during storage of nacelle roofs (6) in the device (1) these are placed alternating their orientation, that is, it goes away changing the direction of nacelle roofs (6).

The device (1) comprises at least a first structure (3) configured to support at least a first nacelle roof (6) and a second structure (4) configured to support at least one additional nacelle roof (6). Figure 2 clearly shows the first structure (3) and the second structure (4).

As shown in the figures, the second structure (4) is attachable to the first structure (3), said second structure (4) comprising at least one arm (5) configured to pivot between a first supporting position of roofs of nacelle (6) and a second position of free passage of roofs of nacelle (6).

Preferably, the device (1) comprises at least one arm (5) for each additional nacelle roof (6) that is to be stored / transported with the device (1). More preferably, the second structure (4) comprises at least one pair of arms (5) intended to support an additional nacelle roof (6) (the first nacelle roof (6) is supported by the first structure (3)). In this case, the arms (5)

25 of the same couple are arranged at the same height on the first structure (3). The rest of the pairs of arms (5) are arranged at the same height on the first structure (3), said height being increasing as the number of additional nacelle roofs (6) increases that are to be supported on the device (1). separation between the pairs of arms (5) along the device (1)

30 must be such that nacelle roofs (6) can be stacked without interference between them.

Said arms (5), when they are in the first support position of nacelle roofs (6), are arranged with their longitudinal direction perpendicular to the direction

35 nacelle roof longitudinal (6). This position has been represented in figure 3 and also corresponds to the position in which the arms (5) are in figure 1,

supporting the roofs of nacelle (6). When the arms (5) pivot to the second position (4) of free passage of nacelle ceilings (6), they pivot 90 ° and are oriented parallel to the longitudinal direction of the nacelle ceilings (6). This position is clearly seen in Figure 4. In this case a set of

5 supports (2) with several devices (1) whose arms (5) are in the second position.

Thus, when the first nacelle roof (6) is placed in the device (1), it rests on the first structure (3) and during this operation the arms (5) of the second structure (4) must be arranged in the second free passage position

10 of nacelle roofs (6) so that the nacelle roof (6) can be placed without the arms (5) of the second structure (4) interfering. Subsequently, as additional nacelle roofs (6) need to be placed, always in order (from the closest to the first structure (3) to the furthest) the arms (5) will be rotated from the second passage position Free to the first support position.

Additionally, as seen in Figure 5, the nacelle roof support device (6) is foldable. For this, the second structure (4) is configured to fold over the first structure (3) in a folded position. This embodiment saves space when the device (1) is not being used and allows

20 have the lowest center of gravity so you can easily manipulate it. The device (1) can be manipulated manually or by using a wheelbarrow.

As can be seen in Figure 5, the first structure (3) comprises support elements (8) for nacelle roofs (6). In this case the support elements (8) are bars that form a square but could also be arms like those of the second structure (4) or have any configuration adapted to support the nacelle roofs (6). Also, the first structure (3) additionally comprises a solid lower base (10) that serves as a counterweight, preventing the device (1) from tipping due to its slenderness. Said lower base (10) is joined

30 by means of two vertical beams (19) to the support element (8).

In an exemplary embodiment such as that of Figure 2, the second structure (4) comprises two vertical tubes (11), joined together by crossbars (12). In this case the arms (5) are linked to said vertical tubes (11) with

35 possibility of rotation around it to move from the first position to the second position and vice versa.

Continuing with Figure 5, it can be seen how the first structure (3) and the second structure (4) comprise complementary joining means configured so that, in the folded position, the second structure (4) is attached to the first structure ( 1), and in a deployed position the second structure (4) is

5 stacked on the first structure (1).

Said complementary joining means comprise tongue and groove pieces. More specifically, the first structure (3) comprises in its lower section, at the height of the base (10), in correspondence with the bottom of the two 10 vertical beams (19), male parts (22) and the second structure (4) comprises in the lower part of the two vertical tubes (11) female parts (21), where in the folded position the male parts (22) of the first structure (3) receive the female parts (21) of the second structure (4), said female parts remaining

(21) on the outside of the male parts (22), and in the deployed position the

15 female pieces (21) are placed on projections (20) of the upper section of the first structure (3). Preferably said projections (20) are the upper ends of the vertical beams (19) of the first structure (3).

During the folding position the first structure (3) remains attached to the

20 second structure (4) by means of screws (7), preferably four (two for each male-female part joint), and the arms (5) collected, as shown in Figure 5. Subsequently, to move to the position of deployed, said screws are removed and the second structure (4) is lifted by the use of a crane that is hooked to a lifting eye (16) disposed in the upper part of said

25 second structure (4). The second structure (4) moves with the crane until the female parts (21) of the second structure (4) are inserted in the projections (20) of the upper section of the first structure (3), that is, in the upper ends of the two vertical beams (19). Once the second structure (4) has been placed on the first structure (3), the screws removed in

30 the previous step is coupled to fix both structures (3,4), as shown in Figure 6.

In an exemplary embodiment, the device (1) additionally comprises blocking elements (9), which can also be seen in Figure 6, configured 35 to block the position of the arms (5) in the first roof support position of nacelle (6) and in the second position of free passage of roofs of nacelle (6). In a

exemplary embodiment as shown in the figure, the blocking elements (9) are pins.

The device (1) is designed to allow the storage of the roofs of

5 nacelle (6) in stacked position. Likewise, as previously described, it is also designed to be able to transport said nacelle roofs (6) both in the manufacturing area and in the assembly areas. In an embodiment of the invention the device comprises wheels (13) arranged at a lower end of the first structure (1) preferably. Said wheels (13) are intended to facilitate the

10 displacement of the device (1) both when it is being used (there are nacelle ceilings (6) already supported) and when it is not yet being used. Likewise, the first structure (3) may comprise housings (17) intended to receive at least one truck fingernail to facilitate the transport of the devices (1) when they are not being used.

15 Generally, when the nacelle roofs (6) of the device (1) or of the assembly (2) are taken, it is done with the help of a crane that allows them to be removed by making a vertical upward movement. In this way they are removed in storage order, from the roof of nacelle (6) that is higher up to the one that is

20 arranged on the supports (8). In another exemplary embodiment in which it is necessary to take one of the nacelle roofs (6) different from that stored in the upper part of the device (1), the desired nacelle roof (6) can be taken by sliding it to the side of the set (2). For this, the arms (5) comprise rotating elements (14) configured to facilitate the sliding of the

25 nacelle roofs (6) on said arms (5) to one side. These rotary elements (14) can be for example rollers with the possibility of rotation on an axis arranged perpendicular to the longitudinal direction of the nacelle roof (6) that rests on the device (1), as shown in the figure 7.

In Figures 3 and 8 it is seen how the arms (5) as well as the support elements (8) respectively, comprise guide wedges (18) which help stably hold square tube profiles (24) from the underside of nacelle roofs (6).

In the assembly (2) intended to support nacelle ceilings (6) of figures 1 and 4 there are six devices (1).

Also an object of the present invention is a nacelle roof support assembly (2) comprising at least four nacelle roof support devices (1) (6) as previously described.

5 The devices (1) are connectable with each other and are arranged facing each other two to two.

Preferably the assembly comprises a plurality of stringers (15) configured to join the devices (1) and connect them together.

10 Figure 9 shows how, in a preferred embodiment, the stringers

(15) comprise handles (23) for easy handling. Likewise, this figure shows supports (25) attached to the lower base (10) of the first structure (3) that are configured to receive the ends of the stringers (15).

15 To prevent said stringers (15) from leaving the supports (25), the supports (25) comprise at least one hole intended to receive at least one shoulder (26) of the beam (15). Likewise, to guarantee the position, there are also pins (27) that are placed through the projection (26) of the crossbar (15) when it is already in its final position housed in the hole of the support (25).
