Description

Universal bracket for root of wind power blade

Technical Field

The utility model relates to a transportation support technical field, in particular to general bracket of wind-powered electricity generation blade root.

Background

The wind power generation equipment converts the kinetic energy of wind into rotary mechanical energy so as to drive a generator to generate power, and the main part for transmitting wind power is a wind power blade. The wind power blade is a flexible blade, and the size of the flexible blade is related to the generated power of the wind power generation equipment. In order to obtain higher power, some wind power blades need to be as long as 75 meters and have high quality as high as 50 tons, which puts high requirements on hoisting.

The root of the wind power blade is cylindrical, so that rolling is easily generated. For this reason, the company has applied for a wind turbine blade root lifting frame (application number: CN 201620486509.6), which disperses the stress on the wind turbine blade root through a plurality of comb-shaped portions, thereby improving the lifting stability. However, the structure is integrated, and the universality is poor only for the type of one wind power blade.

Therefore, there is a need to provide a new structure to improve the versatility of the bracket.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a general bracket of wind-powered electricity generation blade root, be fixed in backup pad 2 on the base 1 including base 1 and detachable, backup pad 2 is fixed in on the base 1 through a plurality of screws 12 that pass the face, one side of backup pad 2 is equipped with arc layer board 22, be equipped with a plurality of blotters 23 on the arc layer board 22, backup pad 2 is the arc of undercut, the middle part top of backup pad 2 is equipped with the ascending support groove 21 of a plurality of openings, the both sides of backup pad 2 still respectively are equipped with a detachable comb plate 3, comb plate 3 is equipped with draw-in groove 31 to the top to one side. The present bracket is split into multiple parts. When beginning to fix, backup pad 2 utilizes bracket 21 to peg graft on the flange face of wind-powered electricity generation blade earlier, then comb plate 3 and the screw joint on the flange face of wind-powered electricity generation blade, fixes on backup pad 2 then, makes backup pad 2 and wind-powered electricity generation blade fixed completely, and backup pad 2 puts up to base 1 at last, fixes with screw 12 again, has just so accomplished the drag and drop. This kind of mode has not only made things convenient for the installation fixed, can make the backup pad 2 of multiple model in order to adapt to the wind-powered electricity generation blade root shape of equidimension not moreover, and base 1 can used repeatedly during the fixed, as long as replace backup pad 2 can, saved the cost.

As shown in fig. 1 and 3, two upper lifting holes 24 are symmetrically formed at both ends of the support plate 2. Two lower lifting holes 11 are symmetrically arranged at two ends of the base 1. The support plate 2 and the base 1 have a large weight, and in practice, a crane is used for assistance, so that the support plate and the base need to be lifted through the

symmetrical lifting holes

11 and 24.

As shown in fig. 1 and 2, the supporting plate 2 is provided with a hook 25 at each side thereof for hooking the upper edge of the base 1. When the supporting plate 2 is just placed on the base 1, the clamping hook 25 can initially position the supporting plate 2 and the base, so that the supporting plate 2 is prevented from falling off, and a worker can vacate hands to fix the supporting plate 2 and the base with screws 12.

As shown in fig. 2, a pair of handles 32 are provided on the outer surface of the comb plate 3. The handle 32 may facilitate the movement and assembly of the comb plate 3.

As shown in fig. 1 to 3, the support plate 2 is provided with a spacer 4 on the other side with respect to the comb plate 3, and the support plate 2 is provided with a plurality of nuts 33 screwed to the spacer 4. The spacers 4 may be such that the nuts 33 are not directly attached to the support plate 2, but the comb plate 3 is clamped to the support plate 2 by means of the spacers 4. If the screw hole of cushion 4 damages and only needs to change 4 parts of cushion, avoid the screw hole directly to establish the huge problem of replacement cost after wearing and tearing in backup pad 2.

As shown in fig. 2 and 3, the two sides of the cushion block 4 are provided with limiting protrusions 41 penetrating through the support plate 2. The position-limiting protrusion 41 enables the cushion block 4 to be initially positioned relatively simply with respect to the support plate 2.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
