Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing equipment technology, and in particular to a modular wind turbine blade transport tooling. Background Technology

[0002] With the continuous growth of global demand for clean energy, wind power technology has developed rapidly. In this process, wind turbine blades, a key component of wind turbine generators, have also shown a significant trend towards larger size, lighter weight, and more diversified aerodynamic performance. The increasing size and variety of blade models place increasingly higher demands on their transportation and support during production, transfer, and installation. Wind turbine blade transportation fixtures, as core equipment specifically designed to support and fix blades, ensuring their safe and stable transport, are crucial. Their design rationality and versatility directly affect transportation efficiency, cost control, and the structural safety of the blades themselves. Therefore, how to provide a universal transportation fixture that can adapt to blades of different specifications has become an urgent technical challenge in this field.

[0003] In the prior art, the applicant noted, for example, a utility model patent with Chinese patent publication number CN216842063U, which discloses a wind turbine blade transfer device. The technical solution of this device mainly includes an active transfer trolley and a driven transfer trolley. The active transfer trolley is equipped with a root support frame for supporting the root of the wind turbine blade; the driven transfer trolley is equipped with a relatively complex displacement adjustment mechanism. This mechanism, through two sets of mutually perpendicular linear guide rails, a two-stage platform, and a slewing bearing, ultimately mounts a blade support frame for positioning and supporting the blade. From its structural design, it can be seen that the inventive concept of this solution lies in achieving longitudinal, lateral, and rotational position adjustment of the blade support frame through a complex guide rail and slewing platform system, in order to transport different wind turbine blades.

[0004] However, the inventors discovered during their research that the existing technical solution has a fundamental flaw in its structural design, making its so-called "adaptability" difficult to achieve in practical applications and resulting in poor versatility. The core problem is that the solution only focuses on the macroscopic spatial position adjustment of the "blade support frame" as a whole component, while completely ignoring the geometric adaptation problem of the support frame itself at the contact interface with wind turbine blades of different specifications.

[0005] Specifically, the "blade support frame" and "root support frame" in this solution, as described, are both rigid structures with fixed shapes. However, different models of wind turbine blades have varying widths, thicknesses, and crucial cross-sectional curvatures (usually complex S-shapes or arcs); their root pitch circle diameters also differ significantly. The fixed-shape "blade support frame" in this prior art can only achieve ideal surface contact with the blade surface of a specific blade model. When used to transport blades with different curvatures or widths, significant geometric differences inevitably arise between the support frame and the blade, causing the contact to degenerate from ideal surface contact to unstable point or line contact. This contact method not only concentrates the clamping force in a very small area, easily causing indentations, scratches, or even structural damage to the delicate composite material surface of the blade, but also significantly reduces the stability and reliability of the clamping due to the small contact area and poor fit, making it prone to loosening during bumpy transportation and posing safety hazards. Similarly, its fixed-shape "root support frame" cannot adapt to the roots of blades with different diameters. Therefore, although this existing technical solution provides the freedom of position adjustment, because its support structure itself does not have the ability to adapt to changes in the geometric shape of the blade, it is essentially still a special tooling and cannot truly solve the industry pain point of adapting to the transportation of blades of different specifications, and its versatility is seriously insufficient. Utility Model Content

[0006] The purpose of this invention is to provide a modular wind turbine blade transport tooling to solve the technical problems of poor tooling versatility and inability to adapt to the transport of blades of different specifications in the prior art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a modular wind turbine blade transport fixture, comprising: a base support module; a blade fixing module disposed on the base support module, the blade fixing module including a clamping assembly and a conformal clamp plate detachably mounted on the clamping assembly; a blade root positioning module disposed on the base support module, the blade root positioning module including: an annular positioning frame; multiple positioning sliders circumferentially distributed inside the positioning frame and slidably disposed radially therein; and a drive adjustment mechanism drivenly connected to the multiple positioning sliders.

[0008] This technical solution achieves structural modularity by decomposing the tooling into a base support module, a blade root positioning module, and a blade body fixing module. The blade root positioning module, through the radial sliding arrangement and drive connection of its multiple positioning sliders, can change its overall positioning diameter, thus precisely adapting to the root of blades with different diameters. Simultaneously, the blade body fixing module, with its detachable conformal clamps, allows for clamp replacement according to the cross-sectional profile of different blades, thereby ensuring a tight fit to blades with varying curvatures. This "dual adjustability" design, addressing the different geometric features at both ends of the blade, fundamentally solves the problem of traditional tooling's inability to simultaneously adapt to changes in diameter and curvature, achieving universal adaptability to blades of various specifications.

[0009] Preferably, the base support module includes multiple support brackets extending vertically upwards; the blade fixing module also includes a fixing seat, which is securely mounted on the support brackets; there are two clamping components, symmetrically arranged on the fixing seat and slidably arranged along its horizontal direction.

[0010] This structure further clarifies the method for adjusting the blade width. A vertical support bracket on the base support module provides a stable mounting foundation for the blade fixing module. The horizontally sliding clamping components are symmetrically positioned on the robust mounting base. This "dynamic-static combination" design not only provides a stable benchmark and guide for precise adjustment of the clamping width but also ensures that the clamping force is applied symmetrically and evenly to both sides of the blade, thereby improving the stability and reliability of the clamping while achieving width adaptation.

[0011] Preferably, the support also includes an arc-shaped support plate disposed on top of the support bracket, the arc-shaped support plate being located between the two clamping components and having an upwardly concave arc-shaped surface; the upper surface of the arc-shaped support plate is also covered with a rubber cushioning pad.

[0012] This structure, in addition to the clamping forces on both sides, adds support from the bottom, forming a three-dimensional wrapping fixation of the blade, further preventing vertical displacement or deformation caused by the blade's own weight. The upwardly concave arc-shaped support plate increases the contact area with the blade, dispersing the support pressure. The addition of a rubber buffer pad provides stable support while absorbing minor vibrations during transportation, avoiding surface damage that may be caused by rigid contact, thus adding a "protective" effect to the overall fixation solution on top of "stability".

[0013] Preferably, each positioning slider in the leaf root positioning module is provided with a set of rollers, and the rollers face the center of the positioning frame.

[0014] This structure transforms the sliding friction during blade root adjustment into rolling friction. This change significantly reduces resistance during adjustment, allowing the drive adjustment mechanism to move the slider more smoothly and precisely, thereby reducing drive energy consumption. More importantly, the rolling contact method avoids scratching or wear on the precision surfaces of the blade root during adjustment, enabling "precise" positioning adjustment of the blade root to be "non-destructive," thus improving the protection level of expensive blades.

[0015] Preferably, the drive adjustment mechanism includes a motor, and the drive adjustment mechanism is integrally mounted on the outside of the positioning frame and adjacent to it.

[0016] This structure significantly shortens the power transmission path by compactly positioning the motor, which serves as the power source, on the outside of the transmission object (positioning frame). This adjacent layout reduces the length and complexity of the transmission chain, thereby reducing energy loss and mechanical errors during transmission. This allows the motor's driving force to be converted into the synchronous radial movement of the positioning slider more efficiently, quickly, and accurately, ensuring both high efficiency and precision in the "non-destructive" adjustment process.

[0017] Preferably, the base support module further includes a rectangular base frame made of welded steel profiles, and the support bracket extends vertically upward from the top surface of the base frame.

[0018] This structure provides fundamental structural protection for all the upper precision modules of the entire tooling. The rectangular base frame, welded from structural steel, has extremely high structural rigidity and torsional resistance, providing a large and stable load-bearing foundation for the entire device. Vertically fixing the support brackets to this base ensures that the relative positions of the upper modules remain unchanged under heavy blade loads and transport vibrations, thus guaranteeing the accuracy of the overall adjustment function and the long-term reliability of the clamping effect.

[0019] In summary, this utility model achieves universal support for blades of different specifications by setting an adjustable diameter blade root positioning module and a blade body fixing module whose width and curvature can be adapted. This solves the problems of poor versatility and resource waste caused by the rigid structure and inability to adapt to various blades in the prior art. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To provide a versatile wind turbine blade transport fixture, this utility model offers a modular wind turbine blade transport fixture. (Refer to...) Figure 1 The tooling includes: a base support module 10; a blade fixing module 30, disposed on the base support module 10, the blade fixing module 30 including a clamping assembly 32 and a conformal clamping plate 33 detachably mounted on the clamping assembly 32; and a blade root positioning module 20, disposed on the base support module 10. The blade root positioning module 20 includes: an annular positioning frame 21; a plurality of positioning sliders 22, circumferentially distributed inside the positioning frame 21 and slidably disposed radially therein; and a drive adjustment mechanism 23, drivenly connected to the plurality of positioning sliders 22.

[0026] This technical solution achieves structural modularity by decomposing the tooling into a base support module 10, a blade root positioning module 20, and a blade body fixing module 30. The blade root positioning module 20, through the radial sliding and driving connection of its multiple positioning sliders 22, can change its overall positioning diameter, thereby precisely adapting to the root 101 of blades with different diameters. Simultaneously, the blade body fixing module 30, through its detachable conformal clamping plate 33, allows for clamping plate replacement according to the cross-sectional profile of different blades, thus ensuring a tight fit to blade bodies 102 with different curvatures. This "dual adjustable" design, addressing the different geometric features at both ends of the blade, fundamentally solves the problem that traditional tooling cannot simultaneously adapt to changes in diameter and curvature, achieving universal adaptability to blades of various specifications.

[0027] As a preferred implementation method, refer to Figure 1 and Figure 4The base support module 10 includes multiple upwardly extending support brackets 12; the blade fixing module 30 also includes a fixing seat 31, which is firmly mounted on the support brackets 12; there are two clamping components 32, symmetrically arranged on the fixing seat 31 and slidably mounted along its horizontal direction. This structure further clarifies the method of adjusting the blade width. By setting the vertical support brackets 12 on the base support module 10, a stable installation foundation is provided for the blade fixing module 30. The horizontally sliding clamping components 32 are symmetrically arranged on the solid fixing seat 31. This "dynamic and static combination" design not only provides a stable benchmark and guide for the precise adjustment of the clamping width, but also ensures that the clamping force can be applied symmetrically and evenly to both sides of the blade 102, thereby improving the stability and reliability of clamping while achieving width adaptation.

[0028] As another preferred implementation method, refer to Figure 4 This fixture also includes an arc-shaped support plate 13 disposed on top of the support bracket 12. The arc-shaped support plate 13 is located between the two clamping components 32 and has an upwardly concave arc-shaped surface. The upper surface of the arc-shaped support plate 13 is also covered with a rubber buffer pad 14. This structure adds support force from the bottom on the basis of the clamping force on both sides, forming a three-dimensional wrapping fixation of the blade 102, further preventing vertical displacement or deformation of the blade due to its own weight. The upwardly concave arc-shaped support plate 13 increases the contact area with the blade 102 and disperses the support pressure. The addition of the rubber buffer pad 14 provides stable support while absorbing minor vibrations during transportation, avoiding surface damage that may be caused by rigid contact, thus adding a "protective" effect to the overall fixing scheme on the basis of "stability".

[0029] As another preferred implementation method, refer to Figure 2 and Figure 3 Each positioning slider 22 in the blade root positioning module 20 is equipped with a set of rollers, which face the center of the positioning frame 21. This structure transforms the sliding friction during blade root adjustment into rolling friction. This change greatly reduces the resistance during adjustment, allowing the drive adjustment mechanism 23 to drive the slider movement more smoothly and precisely, thereby reducing drive energy consumption. More importantly, the rolling contact method avoids scratching or wear on the precision surface of the blade root 101 during adjustment, enabling the positioning adjustment of the blade root to be "precise" yet "non-destructive," thus improving the protection level of expensive blades.

[0030] As another preferred implementation method, refer to Figure 3The drive adjustment mechanism 23 includes a motor, which is integrally mounted on the outside of and adjacent to the positioning frame 21. This structure significantly shortens the power transmission path by compactly arranging the motor, which serves as the power source, on the outside of the transmission object (positioning frame 21). This adjacent arrangement reduces the length and complexity of the transmission chain, thereby reducing energy loss and mechanical errors during transmission. This allows the motor's driving force to be converted into the synchronous radial movement of the positioning slider 22 more efficiently, quickly, and accurately, ensuring both high efficiency and precision in the "non-destructive" adjustment process.

[0031] As another preferred implementation method, refer to Figure 1 The base support module 10 also includes a rectangular base frame 11 welded from structural steel, with the support bracket 12 extending vertically upward from the top surface of the base frame 11. This structure provides fundamental structural protection for all upper precision modules of the entire tooling. The rectangular base frame 11 welded from structural steel has extremely high structural rigidity and torsional resistance, providing a wide and stable load-bearing foundation for the entire device. Vertically fixing the support bracket 12 to it ensures that the relative positional relationship of the upper modules remains unchanged when subjected to heavy blade loads and transportation bumps, thereby guaranteeing the accuracy of the overall adjustment function and the long-term reliability of the clamping effect.

[0032] Specifically, in this embodiment, refer to Figures 1 to 4The modular wind turbine blade transport fixture is clearly divided into three collaborative functional modules, all mounted on a unified base support module 10 to secure a complete wind turbine blade 100. The base support module 10 serves as the foundation of the entire fixture, its core being a low and wide rectangular base frame 11 welded from multiple steel sections, providing excellent structural rigidity and stability. Multiple column-shaped support brackets 12 are vertically fixed upwards from the top surface of the base frame 11 to support the upper functional modules. The blade root positioning module 20 is mounted at one end of the base support module 10, and its main body consists of a large annular positioning frame 21. Multiple positioning sliders 22 are evenly and slidably mounted on the inner circumferential wall of this positioning frame 21, each slider 22 having a set of rollers that can face the center of the frame. On the outer side of the positioning frame 21, a drive adjustment mechanism 23 composed of a motor is installed, which is driven by all the positioning sliders 22 through a transmission system (not shown) (such as a screw and nut mechanism). When it is necessary to fix the blade root 101, the drive adjustment mechanism 23 is activated, causing all positioning sliders 22 to move radially inward synchronously. The rollers on them eventually abut against and support the large circumference of the blade root 101, achieving stable and damage-free positioning. The blade fixing module 30 is installed at the other end of the base support module 10. It includes a fixing seat 31, which is firmly installed on the support bracket 12. On the fixing seat 31, two clamping components 32 that can slide and adjust in the horizontal direction are symmetrically installed. On the inner side of each clamping component 32, a conformal clamping plate 33 is detachably installed. The clamping plate is pre-shaped into an S-shape or arc shape that matches the cross-sectional profile of the blade body 102 to be transported. Below the two clamping components 32, an arc-shaped support plate 13 is also installed on the top of part of the support bracket 12. Its concave surface is covered with a rubber buffer pad 14 to support the blade body 102 from below. During operation, the two clamping components 32 move toward each other, so that the conformal clamping plates 33 on both sides and the arc-shaped support plate 13 below together clamp and support the blade 102, achieving dual adaptation to the blade width and curvature.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the scope of implementation of the present utility model. All equivalent changes and modifications made in accordance with the scope defined by the claims of the present utility model shall still fall within the protection scope of the present utility model.
