Description

Technical Field

[0001] This invention relates to the field of wind turbine blade technology, and in particular to a tooling and method for heating, bonding and curing segmented blade main beam support. Background Technology

[0002] To address some of the challenges of traditional wind turbine blades in terms of transportation, installation, maintenance, and efficiency, and with the continuous development of the wind power industry, segmented wind turbine blades have emerged as an innovative design. These blades typically divide a single blade into multiple smaller segments or modules, each of which can be manufactured, transported, and installed independently. This significantly increases the size and volume of the final wind turbine blade, thereby improving the performance and efficiency of wind power generation.

[0003] The main beam of a segmented wind turbine blade is a key part of the blade structure. During the manufacturing process, after the segmented blade main beam is produced, it needs to be bonded and fixed to the rest of the blade. However, due to its large size, it is difficult to adjust the position of the segmented blade main beam when it is hoisted to the bonding fixture, which can easily lead to positioning errors, affecting the subsequent bonding and curing effect, and thus affecting the forming quality of the wind turbine blade.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 10 The segmented blade main beam support heating bonding and curing fixture shown includes: a frame 10, a support positioning mechanism 20 and a heating curing mechanism 30; a support longitudinal beam 11 is provided on the top of the frame 10 along the horizontal direction of the length of the segmented blade, which is used to fix the support positioning mechanism 20 and the heating curing mechanism 30. The support positioning mechanism 20 is used to position the blade main beam to a set position. It includes several sets of adjustable support components 21 and sway support components 22. The adjustable support components 21 and sway support components 22 are arranged along the length direction of the support longitudinal beam 11. The adjustable support components 21 are located at a position where the gap distance between the blade main beam and the support longitudinal beam 11 is less than the gap threshold, and the sway support components 22 are located at a position where the gap distance between the blade main beam and the support longitudinal beam 11 is greater than the gap threshold. The heating and curing mechanism 30 is used to bond and cure the positioned blade main beam and the blade body into one piece. It includes a support curved plate 31 arranged along the length of the top of the support longitudinal beam 11. The side of the support curved plate 31 facing the segmented blade forms a complete fit with the segmented blade. The support plate 31 has multiple positioning holes 31a spaced along its length. These positioning holes 31a correspond to the adjustable support assembly 21 and the sway support assembly 22, respectively. The adjustable support assembly 21 includes a pair of legs 211 arranged on both sides of the support longitudinal beam 11, and the height of each leg 211 can be adjusted individually. The sway support assembly 22 includes a support rod 221 and a pad 222. There are two pads 222, located at both ends of the support rod 221. The support rod 221 can be swayed around the middle. The legs 211 and the pads 222 pass through the corresponding positioning holes 31a and contact the outer surface of the blade main beam.

[0024] By using adjustable support assembly 21 and sway support assembly 22, the tooling can be adapted to blade main beams of different sizes, and the position of the blade main beam can be precisely adjusted to ensure accurate alignment with the rest of the blade, thereby reducing positioning errors. By setting support curved plate 31 in heating and curing mechanism 30 to form a complete fit with the blade, it helps to improve the quality and efficiency of bonding and curing, and ensure the forming quality of wind turbine blades.

[0025] The steps for bonding and curing the segmented blades and blade main beam using the above-mentioned segmented blade main beam support heating bonding and curing fixture are as follows: The segmented blades and blade main beam are hoisted onto the frame 10. Because the shapes of the various cross-sections of the segmented blades are different, the gap distance from the blade main beam to the support longitudinal beam 11 varies along the length direction. To ensure that support is provided for both the segmented blades and blade main beam along the length direction, adjustable support components 21 and sway support components 22 are arranged along the length direction of the support longitudinal beam 11. The adjustable support component 21 is located between the blade main beam and the support longitudinal beam 11. When the gap distance between the blade main beam and the support longitudinal beam 11 is less than the gap threshold, the support feet 211 on both sides provide point support for the blade main beam, which is highly flexible in the narrow support space. The swaying support component 22 is located when the gap distance between the blade main beam and the support longitudinal beam 11 is greater than the gap threshold. The swaying pad 222 provides surface support for the blade main beam, which increases the stress area and greatly reduces the occurrence of stress deformation during bonding and curing. The pad 222 is made of flexible material, which further eliminates positional errors during support and hoisting, and prevents scratches on the blade and the vacuum bag film for subsequent heating and bonding curing, thus ensuring the bonding effect. By adjusting the height of the adjustable support assembly 21 and the sway support assembly 22, the support leg 211 and the pad 222 pass through the corresponding positioning hole 31a and form a contact support with the outer side of the blade main beam. The blade main beam is positioned at the set position. The size of the positioning hole 31a can be set according to the size of the corresponding support leg 211 and the pad 222, so that the support leg 211 and the pad 222 can pass freely through the positioning hole 31a, and have space to accommodate the pad 222 swinging under the action of the support rod 221, and can ensure the support function of the support curved plate 31 on the blade main beam. Adjust the position of the heating and curing mechanism 30, arrange the vacuum film and heating blanket on the support curved plate 31, and ensure that the side of the support curved plate 31 facing the segmented blade forms a complete fit with the segmented blade after the arrangement is completed, so as to bond and cure the segmented blade and the blade main beam; that is, to form a conformal tooling, the bonding gap between the heating blanket on the support curved plate 31 and the blade main beam is greatly reduced, ensuring the consistency of temperature during bonding and curing, thereby ensuring the forming effect of the wind turbine blade. The heating blanket can be fixed to the support curved surface in the form of Velcro, simplifying the disassembly and installation process.

[0026] Based on the above embodiments, the adjustable support assembly 21 further includes an auxiliary support seat 212 and a diagonal brace 213. The auxiliary support seat 212 is bent into a right-angle structure, with one right-angle side fixedly connected to the side wall of the support longitudinal beam 11, and the support leg 211 screwed to the end of the other right-angle side, with its axis perpendicular to the other right-angle side. The two ends of the diagonal brace 213 are respectively fixedly connected to the two right-angle sides of the auxiliary support seat 212. The adjustable support assembly 21 with the addition of the auxiliary support seat 212 and the diagonal brace 213 can provide additional stability and adjustment functions. The auxiliary support seat 212 and the diagonal brace 213 form a triangular stability structure, which helps to maintain the stability of the blade main beam during the bonding and curing process. The screwed arrangement of the support leg 211 makes the height adjustment more precise and convenient, and the position of the blade main beam can be quickly and flexibly adjusted to ensure accurate positioning.

[0027] Based on the above embodiments, the sway support assembly 22 further includes a support plate 223, a pin 224, and two adjusting bolts 225. The support plate 223 is connected to the support longitudinal beam 11, and a deflection cavity 223a is formed on the side of the support plate 223 away from the support longitudinal beam 11. The support rod 221 is disposed in the deflection cavity 223a, and its middle part is rotatably connected to the support plate 223 via the pin 224. The two adjusting bolts 225 are respectively connected to the two ends of the support plate 223 and the support rod 221. The support plate 223 and the pin 224 enable the support rod 221 to deflect... The rotating cavity 223a allows for free rotation, providing additional adjustment dimensions and enabling fine-tuning of the blade main beam in more directions, eliminating positional errors during support and hoisting. The two adjusting bolts 225 can quickly adjust the position of the support rod 221, simplifying the entire adjustment process and allowing precise control over the position of the support rod 221. This allows for meticulous adjustment of the blade main beam position to accommodate different gaps and angles. After adjustment, the support plate 223 and the support rod 221 are connected by the adjusting bolts 225 to form a stable support platform, ensuring the stability of the support.

[0028] Based on the above embodiments, the sway support assembly 22 further includes a screw 226, a square tube welding plate 227, a nut 228, a top block 229, a baffle 2210, a rolling bearing 2211, a first fastener 2212, and a washer 2213. The square tube welding plate 227 is fixedly connected to the support longitudinal beam 11. The screw 226 passes through the square tube welding plate 227, with one end located on the side of the support longitudinal beam 11 away from the support plate 223, and the other end set opposite to the support plate 223 and screwed to the nut 228. The support plate 223 is recessed on the side facing the support longitudinal beam 11 to form a rotating cavity 223b. The rolling bearing 2211 is confined in the rotating cavity 223b. The baffle 2210 is located at the end of the rotating cavity 223b and forms an abutment with one end of the rolling bearing 2211. The gasket 2213 is disposed in the rotating cavity 223b from the side where the deflection cavity 223a is located and forms an abutment with the other end of the rolling bearing 2211. The top block 229 is located between the rolling bearing 2211 and the nut 228, and the rolling bearing 2211 is sleeved on the stepped surface of the top block 229 and rotatably connected to the top block 229. The first fastener 2212 passes through the washer 2213, the rolling bearing 2211 and the top block 229 in sequence from one side of the deflection cavity 223a, and is fixedly connected to the end face of the screw 226.

[0029] By installing a rolling bearing 2211 at the end of the screw 226, the screw 226 rotates, driving the upper oscillating support assembly 22 to move up and down, thus adapting to the blade main beam at different lifting heights. After the blade main beam reaches the required height, the height and angle of the corresponding pads 222 can be changed by adjusting the bolts 225 on both sides, thereby adapting to the position and angle of the blade main beam, greatly increasing the versatility and flexibility of the tooling. A rotating cavity 223b is set in the support plate 223, and a rolling bearing is installed in the rotating cavity 223b. The bearing 2211 is limited by the top block 229 and the baffle 2210 to prevent the rolling bearing 2211 from coming out of the rotating cavity 223b during rotation and lifting. The use of the screw 226 and the nut 228 makes the positioning more accurate. The fixed connection between the square tube welding plate 227 and the support longitudinal beam 11 enhances the stability of the entire support structure. The use of the gasket 2213 can protect the first fastener 2212 and the rolling bearing 2211, reduce damage caused by direct contact, and also facilitate installation and maintenance.

[0030] Based on the above embodiment, a spacer 2214 is also sleeved on the outer shaft surface of the first fastener 2212. The spacer 2214 is located in the middle of the rolling bearing 2211, and its two ends abut against the end faces of the shim 2213 and the top block 229 respectively. The spacer 2214 helps to more accurately control the relative position between the rolling bearing 2211, the shim 2213 and the top block 229, forming a stable support structure, reducing the vibration caused by the rotation of the rolling bearing 2211 during rotation, improving the stability of the system and the positioning accuracy of the blade main beam, and also helps to disperse the force, reduce the local stress of the rolling bearing 2211, the shim 2213 and the top block 229, and improve the durability and service life of the entire support system.

[0031] Based on the above embodiments, the sway support assembly 22 further includes a guide sleeve 2215, a guide rod 2216, a washer 2217, and a second fastener 2218; the guide sleeve 2215 is fixedly connected to the square tube welding plate 227, and the guide rod 2216 and the screw 226 are arranged parallel to each other and are located in the middle of the guide sleeve 2215; A horizontal extension plate 223c is provided on the side of the support plate 223 facing the guide sleeve 2215. The extension plate 223c is positioned opposite to the end face of the guide sleeve 2215. One end of the guide rod 2216 passes through the guide sleeve 2215 and is located inside the support longitudinal beam 11. The other end is fixedly connected to the extension plate 223c by the second fastener 2218. The washer 2217 is clamped between the second fastener 2218 and the end face of the guide rod 2216.

[0032] The guide post and guide sleeve 2215 work together to prevent the support plate 223 from twisting as the screw 226 rotates, thus preventing deviation between the pad 222 and the support position set on the blade main beam, effectively ensuring the positioning accuracy of the blade main beam. The fixed connection between the guide sleeve 2215 and the square tube welding plate 227, and the fixed connection between the guide rod 2216 and the support plate 223, provide additional stability, ensuring that the guide post can move vertically along the guide sleeve 2215 and guaranteeing the guiding function. The use of the washer 2217 helps reduce wear between the second fastener 2218 and the guide rod 2216, extending the service life of the component.

[0033] Based on the above embodiments, the supporting curved plate 31 forms a fixed section 311 and a movable section 312 on one side perpendicular to the length direction of the supporting longitudinal beam 11. The fixed section 311 is fixedly connected to the supporting longitudinal beam 11. The heating and curing mechanism 30 includes a driving part 32 and a hinge part 33. The driving part 32 is fixedly disposed at both ends of the supporting longitudinal beam 11 and fixedly connected to the bottom surface of the movable sections 312 on both sides, for driving the movable sections 312 to rotate relative to the fixed section 311. The hinge part 33 includes a plurality of hinges 331 spaced apart along the length direction of the supporting curved plate 31. The hinges 331 are located on the side of the supporting curved plate 31 away from the wind turbine blade and rotate... The fixed section 311 and the movable section 312 are connected. The introduction of the movable section 312 allows for more precise adjustment of the support curved plate 31 to better fit the shape of the segmented blades, improving the quality and efficiency of bonding and curing. In the subsequent vacuum film arrangement operation, the movable section 312 can be driven to rotate relative to the fixed section 311 by the drive unit 32, so that the movable sections 312 on the left and right sides can be flipped downward at a certain angle to expose the space for arranging the vacuum film, simplifying the operation. Furthermore, the connection is made by multiple hinges 331 distributed at intervals, ensuring the stability of the entire support curved plate 31 structure, making the entire production process more efficient and reliable.

[0034] Based on the above embodiments, the drive unit 32 includes a first hinge seat 321, a second hinge seat 322, an adapter 323, and a drive member 324. The first hinge seat 321 is fixedly connected to the side of the supporting longitudinal beam 11. The drive member 324 is rotatably mounted on the first hinge seat 321. The second hinge seat 322 is fixedly connected to the side of the movable section 312 away from the blade main beam. The adapter 323 is fixedly mounted on the output end of the drive member 324 and rotatably connected to the second hinge seat 322. The first hinge seat 321 and the second hinge seat 322... The drive unit 32 is fixedly connected to the support longitudinal beam 11 and the movable section 312 respectively, which enhances the stability of the entire drive unit 32 connection. When the movable section 312 is rotated at a certain angle, the drive action of the drive component 324 causes the second hinge seat 322 and the adapter 323 to rotate, which in turn causes the drive component 324 and the first hinge seat 321 to rotate, thereby causing the movable section 312 to rotate around the hinge 331. This allows the support curved plate 31 to fit tightly against the blade main beam and the segmented wind turbine blade, reducing the bonding gap and ensuring the bonding effect.

[0035] Based on the above embodiments, the height of the frame 10 is adjustable, which facilitates the operation of workers to place the vacuum film and heating blanket, and to set the wind turbine blades at a suitable height for easy placement into the curing oven; and an auxiliary support 12 is provided on one side, with the auxiliary frame 10 and the supporting longitudinal beam 11 arranged parallel to each other, to provide support for the trailing edge of the segmented wind turbine blades. The auxiliary support 12 provides additional support points for the segmented blades, enhancing the stability of the entire structure and helping to maintain the stability of the blades during the production and curing process.

[0036] This invention also provides a method for heating, bonding, and curing a segmented blade main beam support using a heat-bonding and curing fixture. The method includes the following steps: The segmented blades and blade main beams are hoisted onto the frame 10; Adjust the height of the adjustable support assembly 21 and the sway support assembly 22 so that the support feet 211 and the pads 222 pass through the corresponding positioning holes 31a and form a contact support with the outer side of the blade main beam, and the blade main beam is positioned at the set position. Adjust the position of the heating and curing mechanism 30, arrange the vacuum film and heating blanket on the support curved plate 31, and make the side of the support curved plate 31 facing the segmented blade fully fit with the segmented blade after the arrangement is completed. The segmented blades and blade main beams are bonded and cured.

[0037] The specific steps of the above-mentioned segmented blade main beam support heating, bonding and curing method have been described in the above embodiments and will not be repeated here.

[0038] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
