Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing technology, and in particular to a tooling for supporting the web of wind turbine blades. Background Technology

[0002] The web of a wind turbine blade is a core structural reinforcement component inside the blade. The C-shaped opening at its edge is used for bonding with the blade's main spars and is a critical part for stress transmission. Because the web's C-shaped opening usually has a complex curved surface structure and a large overall size, it is highly susceptible to deformation, cracking, or damage due to external forces during production, transportation, and assembly, which can affect the blade's structural strength and service life.

[0003] Existing technologies for supporting C-shaped openings in web plates have several drawbacks: Firstly, traditional fixed supporting fixtures have fixed dimensions and cannot adapt to the dimensions and curvature variations of C-shaped openings in web plates of different specifications and models. This necessitates manufacturers equipping different web plate models with dedicated fixtures, significantly increasing production costs and storage space. Secondly, the support surfaces of existing supporting fixtures are mostly rigid structures, resulting in poor fit with the web plate C-shaped opening, insufficient uniformity of support and reasonable stress distribution, and a tendency to generate stress concentrations in localized areas, which exacerbates the risk of damage to the web plate. Furthermore, existing fixtures can only achieve a single support function and cannot solve the problem of uneven adhesive thickness during the bonding process between the web plate and the main beam. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a tooling for supporting the web of wind turbine blades, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a tooling for supporting the web of a wind turbine blade, comprising: a support drive component, a support connecting rod, a spacing adjustment component, a bushing, and a rotatable fitting component;

[0006] The output end of the support drive component is fixedly connected to the support connecting rod, and is used to drive the support connecting rod to extend and retract axially to press against the main flange of the wind turbine blade web.

[0007] The spacing adjustment component is assembled on the support rod and is used to adjust the radial spacing between the support rod and the C-shaped opening of the wind turbine blade web.

[0008] The rotatable fitting component is hinged to the end of the support rod away from the support drive component via the bushing, so that the rotatable fitting component can rotate around the axis of the bushing to fit the inner curved surface of the C-shaped opening of the web.

[0009] The rotatable fitting component has a flexible buffer layer on the fitting surface facing the C-shaped opening of the web.

[0010] In one embodiment, the support drive component is a jack or a telescopic cylinder, and the support drive component is detachably connected to the support connecting rod.

[0011] In one embodiment, the flexible buffer layer is any one of an EVA pad, a rubber pad, or a silicone pad, and the flexible buffer layer is fixed to the mating surface of the rotatable adhesive by adhesive or snap-fit.

[0012] In one embodiment, the spacing adjustment component is a threaded adjuster that is threadedly connected to the support link, and its axial position on the support link is changed by rotating the spacing adjustment component.

[0013] In one embodiment, at least two support rods are provided, which are symmetrically distributed on both sides of the support drive member. Each support rod is correspondingly equipped with the spacing adjustment member, the bushing, and the rotatable fitting member.

[0014] In one embodiment, the bushing is interference-fitted with the support link, and the rotatable fitting is clearance-fitted with the bushing, allowing the rotatable fitting to rotate freely around the bushing.

[0015] In one embodiment, two support rods are fixedly connected to the output end of the support drive component via a connecting beam, and the connecting beam is coaxially arranged with the support drive component.

[0016] In one embodiment, the rotatable fitting includes a rotating assembly, a first support assembly, and a second support assembly;

[0017] The first support component is an arc-shaped plate structure facing the inner curved surface of the C-shaped opening of the web plate, and its concave arc surface constitutes the fitting surface for contacting the C-shaped opening of the web plate.

[0018] The rotating assembly includes a connecting part fixedly connected to the second support assembly. The connecting part is hinged to the end of the second support link through the bushing, so that the second support assembly can rotate around the axis of the bushing to adapt to the inner curved surface of the web C-shaped opening with different curvatures.

[0019] As can be seen from the above, the tooling provided by this utility model for supporting the web of wind turbine blades has a simple design structure, is easy to operate, improves efficiency, and has high versatility, meeting the needs of webs of various blade models. The combination design of the C-shaped opening and the flexible buffer layer achieves curved contact with the web C-shaped opening, greatly reducing local stress concentration during the support process and effectively preventing web damage. The support flange for the web can also reduce the problem of glue thickness at this point. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] like Figure 1As shown, this utility model provides a tooling for supporting the web of a wind turbine blade, such as... Figure 1-2 As shown, this embodiment provides a tooling for supporting the web of a wind turbine blade, including a support drive component 1, a support connecting rod 2, a spacing adjustment component 3, a bushing 4, a rotatable fitting component 5, and a flexible buffer layer 6.

[0029] The support drive component 1 is a jack, with both ends fixedly connected to two symmetrically arranged support rods 2, so that the driving force of the jack can be evenly transmitted to the two support rods 2, realizing synchronous expansion and contraction along the axial direction, and thus tightening the main flange of the web C-shaped opening.

[0030] like Figure 3 As shown, the spacing adjustment component 3 is a threaded adjuster, which is connected to the support rod 2 by a thread. By rotating the spacing adjustment component 3 clockwise or counterclockwise, its axial position on the support rod 2 can be changed, thereby adjusting the radial spacing between the support rod 2 and the web C-shaped opening, and adapting to C-shaped openings of different sizes.

[0031] The bushing 4 is interference-fitted with the end of the support rod 2 away from the connecting support drive component 1. The rotatable fitting component 5 is an arc-shaped plate structure, which is clearance-fitted with the bushing 4, so that the rotatable fitting component 5 can rotate freely around the axis of the bushing 4, with a rotation angle range of 0-90°, ensuring that it can fit tightly with the complex inner curved surface of the web C-shaped opening.

[0032] The flexible buffer layer 6 is made of EVA pad, which is fixed to the mating surface of the rotatable mating part 5 facing the C-shaped opening by adhesive. The EVA pad has good elasticity and cushioning performance, which can effectively disperse the support stress and avoid damage to the web surface.

[0033] like Figure 4 As shown, the rotatable fitting component includes a rotating assembly 50, a first support assembly 51, and a second support assembly 52.

[0034] The first support component 51 is an arc-shaped plate structure facing the inner curved surface of the C-shaped opening of the web plate. Its concave arc surface forms a fitting surface for contacting the C-shaped opening of the web plate.

[0035] The rotating assembly 50 includes a connecting part that is fixedly connected to the second support assembly 52. ​​The connecting part is hinged to the end of the second support link 52 through the bushing, so that the second support assembly 52 can rotate around the axis of the bushing 4 to adapt to the inner curved surface of the web C-shaped opening with different curvatures.

[0036] The usage process of this embodiment is as follows:

[0037] The operator places the tooling at the preset support position on the web of the wind turbine blade, so that the two support rods 2 correspond to the two sides of the C-shaped opening on the web respectively;

[0038] Adjust the support drive component 1 (jack) to drive the support connecting rod 2 to extend and retract axially until it is pressed against the main flange of the web plate, thereby achieving axial positioning support;

[0039] Rotary spacing adjustment component 3 (thread adjuster) adjusts the radial spacing between the support connecting rod 2 and the C-shaped opening, so that the rotatable fitting component 5 is close to the inner curved surface of the C-shaped opening;

[0040] The rotatable fitting part 5 can be manually rotated to make its arc-shaped fitting surface fully fit the inner curved surface of the C-shaped opening, and the flexible buffer layer 6 (EVA pad) is in close contact with the surface of the C-shaped opening.

[0041] Check the stability of the support and complete the support work after confirming that there are no problems.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] By adjusting the axial extension and retraction of the support drive component, the radial spacing of the spacing adjustment component, and the angle adaptation of the rotatable fitting component, the tooling can be adapted to the web of wind turbine blades of different models and sizes, eliminating the need for dedicated tooling for each model and significantly reducing production costs and storage space.

[0044] The rotatable fitting component can rotate around the bushing to achieve conformal fitting with the inner curved surface of the C-shaped opening of the web. Combined with the buffering effect of the flexible buffer layer, it effectively disperses the support stress, avoids local stress concentration, and significantly reduces the risk of deformation, cracking or surface damage of the web during the support process.

[0045] By supporting the drive components to tighten the main flange of the web plate, the thickness of the adhesive layer during the bonding process between the web plate and the main beam can be effectively controlled, solving the problem of uneven adhesive thickness and improving the bonding strength and overall structural stability of the blade.

[0046] The overall structure consists of multiple modular components, which are easy to assemble and disassemble. Operators can complete the support operation by adjusting the support drive, spacing adjustment and rotatable fitting parts, which greatly improves the efficiency of use.

[0047] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0048] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
