Description

Technical Field

[0001] The invention relates to the technical field of wind turbine blade production, and in particular to a modular wind turbine blade lower auxiliary beam positioning and bonding device and a working method. Background Art

[0002] As a component that captures wind energy in a wind turbine, blades play an extremely important role in wind turbines. With the development of the wind energy industry, the size of blades has gradually increased. As the size of blades increases, the weight of blades also increases, which puts higher requirements on wind turbines. At the same time, large-scale tooling is required to realize the manufacture of blades, which requires a lot of space. Therefore, how to achieve lightweight and modularization of large-size wind turbine blades has become its development direction.

[0003] like Figure 1 As shown in the structural diagram of the wind turbine blade, it is necessary to first splice the modular blade root section, blade middle section and blade tip section into a blade skeleton, and install the main beam and auxiliary beam in the main beam groove and the auxiliary beam groove. The auxiliary beam includes an upper auxiliary beam and a lower auxiliary beam. The auxiliary beam positioning and bonding method of the modular wind turbine blade is generally to use a crane to lift the upper auxiliary beam and place the auxiliary beam into the upper auxiliary beam groove. However, it is inconvenient to install the lower auxiliary beam at the bottom of the wind turbine blade. Generally, the entire wind turbine blade is rotated 180° so that the lower auxiliary beam groove faces upward, and then the lower auxiliary beam is hoisted.

[0004] However, the above method has the following problems: due to the large size of the wind turbine blade, the tooling for flipping it 180° is large and complicated, and the above method of bonding the auxiliary beam requires waiting for the bonded upper auxiliary beam to dry, which takes about a week before it can be flipped 180° and the lower auxiliary beam can be installed, resulting in a long production cycle and a large workload. Therefore, a modular wind turbine blade lower auxiliary beam positioning and bonding device is needed to facilitate the positioning and bonding of the lower auxiliary beam.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0015] Furthermore, the suction cup is one of rectangular, circular, and elliptical.

[0016] Furthermore, limiting columns are provided on both sides of the support block in the width direction, which are used to limit the downward sliding of the lower auxiliary beam when it is lifted or lowered.

[0017] Furthermore, the suction cup has a cavity structure with an opening on one side, an air inlet is provided at the bottom of the suction cup, at least one support bar is provided in the cavity, and a plurality of grooves are provided on the support bar for conducting the air in the cavity.

[0018] Furthermore, a cross bar is horizontally provided on the bracket, and a guide column, a first driving member and a screw elevator are vertically provided between the cross bar and the base. The first driving member drives the screw elevator to rotate and drives the guide column to perform lifting motion.

[0019] Furthermore, it also includes a second driving member for driving the hard support component to perform lifting motion and a third driving member for driving the soft support component to perform lifting motion.

[0020] The present invention also includes a working method of the modular wind turbine blade lower auxiliary beam positioning and bonding device as described above, comprising:

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] like Figures 2 to 9 As shown: a modular wind turbine blade lower auxiliary beam positioning and bonding device, comprising a plurality of support modules 100 sequentially arranged along the length direction of the lower auxiliary beam 015b;

[0049] Each support module 100 includes a base 1 and a bracket 2 arranged on the base 1, and at least one hard support component 3 and a plurality of soft support components 4 arranged at intervals are arranged on the bracket 2;

[0050] The bracket 2 performs lifting motion, and is used to drive the hard support component 3 and the soft support component 4 to perform lifting motion synchronously;

[0051] Each hard support assembly 3 performs lifting movement independently, and the hard support assembly 3 includes a support block 31, which is used to limit the axial and chordal positions of the lower auxiliary beam 015b;

[0052] Each soft support component 4 performs lifting and lowering movement independently, and includes a suction cup 41 and a fine-tuning component 42 arranged at the bottom of the suction cup 41. The suction cup 41 is used to adsorb the lower auxiliary beam 015b to prevent the lower auxiliary beam 015b from sliding down and deforming. The fine-tuning component 42 includes an angle adjustment component 421 and a chord-wise adjustment component 422. The angle adjustment component 421 is used to fine-tune the inclination angle of the suction cup 41, and the chord-wise adjustment component 422 is used to adjust the chord-wise position of the suction cup 41.

[0053] By setting a plurality of support modules 100 in sequence along the length direction of the lower auxiliary beam 015b, each support module 100 drives the hard support component 3 and the soft support component 4 to perform synchronous lifting and lowering movements through the lifting and lowering of the bracket 2, the lower auxiliary beam 015b is moved to the auxiliary beam slot position, the hard support component 3 is lowered, and the lower auxiliary beam 015b is pushed into the auxiliary beam slot by the soft support component 4, and then the chord position and the inclination angle of the lower auxiliary beam 015b are adjusted by the fine-tuning component 42, so that the position of the lower auxiliary beam 015b is adapted to the position of the lower auxiliary beam slot, after the adjustment is completed, the bracket 2 is lowered to make the lower auxiliary beam 015b away from the lower auxiliary beam slot, after the guide fiber cloth 015c is laid on the surface of the lower auxiliary beam 015b, the bracket 2 is raised to make the lower auxiliary beam 015b enter the auxiliary beam slot, and then the lower auxiliary beam 015b is moved to the auxiliary beam slot. First, adjust the position and angle of the lower auxiliary beam 015b in the lower auxiliary beam groove, and then uniformly lower the support modules 100 by a certain distance to facilitate the laying of the guide fiber cloth 015c. The hard support component 3 limits the axial and chordal positions of the lower auxiliary beam 015b, and the soft support component 4 supports the lower auxiliary beam 015b by adsorption, so as to prevent the lower auxiliary beam 015b from sliding down during the rising process. The auxiliary beam is adjusted by the micro-adjustment component to ensure the correct position of the auxiliary beam, which reduces the difficulty of installing the lower auxiliary beam 015b. The installation of the lower auxiliary beam 015b can be completed without turning the blade 180°, thereby eliminating the need to turn over the tooling and the period of waiting for the upper auxiliary beam 015a to dry, simplifying the installation process, reducing the difficulty of installing the lower auxiliary beam 015b, and shortening the production cycle.

[0054] Through the combination of the hard support component 3 and the soft support component 4, the lower auxiliary beam 015b is accurately positioned and limited. The precise positioning system ensures the perfect docking of the auxiliary beam and the auxiliary beam groove, thereby improving the installation accuracy and overall performance of the blade.

[0055] The traditional method of installing the lower auxiliary beam 015b requires rotating the entire wind turbine blade 180°, which is a complex, time-consuming and labor-intensive process. The modular wind turbine blade lower auxiliary beam positioning and bonding device of the present invention does not require rotating the blade. Through the lifting and lowering movement of the bracket 2 and the adsorption function of the soft support component 4, the lower auxiliary beam 015b can be directly and accurately placed in the groove, which greatly simplifies the installation process and reduces the difficulty of installation.

[0056] Since there is no need to rotate the wind turbine blades 180°, the demand for large tooling equipment and space is reduced, which not only saves the cost of tooling equipment, but also reduces the occupancy of the installation site and improves the space utilization rate of the factory and the site.

[0057] The fine-tuning component 42 can adjust the chordal position and inclination angle of the auxiliary beam to adapt to auxiliary beams of different cross-sections and shapes, ensuring a close fit between the auxiliary beam and the groove. This is particularly important when the auxiliary beam has a complex free-form surface, and can effectively meet the installation requirements of auxiliary beams of various shapes.

[0058] As a preferred embodiment of the above embodiment, the angle adjustment component 421 includes a chassis 421a and a hinged portion 421b protruding from the chassis 421a, and an angle adjustment rod 421c passing through the bottom plate, one end of the angle adjustment rod 421c is connected to the suction cup 41; a protruding connecting portion 413 is provided at the bottom of the suction cup 41, and a rotating shaft 421d is provided between the connecting portion 413 and the hinged portion 421b, and the connecting portion 413 is rotated along the axis of the rotating shaft 421d by adjusting the length of the adjusting rod, so as to adjust the angle of the suction cup 41; on the one hand, the angle of the suction cup 41 can be accurately adjusted through the angle adjustment component 421, so that the suction cup 41 can better adapt to the lower auxiliary beam groove of different angles of the lower auxiliary beam 015b, ensuring the accuracy of the lower auxiliary beam 015b being installed in the lower auxiliary beam groove; on the other hand, the angle adjustment component 421 reduces the installation error caused by the improper angle of the suction cup 41, ensuring the close fit between the lower auxiliary beam 015b and the lower auxiliary beam groove.

[0059] In this embodiment, the chord-wise adjustment assembly 422 includes a fixed seat 422a disposed at the bottom of the chassis 421a and slides 422b disposed on both sides of the fixed seat 422a, the slides 422b are connected to the chassis 421a, and a first screw rod 422c and a guide rod 422d are disposed between the fixed seat 422a and the slides 422b. The screw rods are rotated to drive the slides 422b on both sides to move in the same direction, thereby driving the chord-wise fine adjustment of the chassis 421a to ensure that the lower auxiliary beam 015b is accurately positioned in the chord-wise position in the lower auxiliary beam groove; specifically, on the one hand, the chord-wise adjustment assembly 422 enables the chassis 421a to be adjusted within a smaller range. On the other hand, the chord-wise adjustment assembly 422 can accurately position the auxiliary beam in the chord-wise position through the precise control of the screw rod, thereby ensuring the accurate docking of the auxiliary beam with the auxiliary beam groove and improving the installation accuracy. In addition, the fine-tuning function effectively reduces the problems caused by position errors during the installation process and improves the accuracy and reliability of the overall installation. In addition, the guide rod 422d provides guidance for the movement of the slide 422b, so that the slide 422b remains stable during the movement without offset or shaking, thereby ensuring the stable installation of the auxiliary beam.

[0060] Among them, the suction cup 41 is rectangular, circular, or elliptical, and in the present embodiment, the suction cup 41 is rectangular, and the suction cup 41 is rectangular, which can provide a larger contact area. Due to the larger contact area, the rectangular suction cup 41 can distribute the adsorption force more evenly, reduce the sliding and displacement of the auxiliary beam during the installation process, and ensure the stability of its position; due to the rectangular design of the suction cup 41, it can cover a larger area, effectively distribute the adsorption force, reduce local stress concentration, and protect the structural integrity of the auxiliary beam; due to the large shape and contact area of ​​the suction cup 41, the positioning and bonding of the auxiliary beam can be more easily achieved during operation, simplifying the entire operation process.

[0061] In this embodiment, limit columns 32 are provided on both sides of the support block 31 in the width direction, which are used to limit the downward sliding of the lower auxiliary beam 015b during lifting. On the one hand, the stability of the auxiliary beam during the movement and positioning process is ensured; on the other hand, the limit columns 32 provide additional support points, reducing the risk of accidental sliding or falling off of the lower auxiliary beam 015b during lifting and adjustment, thereby enhancing operational safety.

[0062] As a preferred embodiment of the above embodiment, the suction cup 41 has a cavity structure with one side open, an air intake port 411 is provided at the bottom of the suction cup 41, at least one support bar 412 is provided in the cavity, and a plurality of grooves 412a are provided on the support bar 412 for conducting the air in the cavity. Specifically, on the one hand, the support bar 412 provides additional supporting force, which helps to maintain the shape of the lower auxiliary beam 015b, and reduces the local stress of the suction cup 41 on the surface of the auxiliary beam by optimizing the adsorption area, thereby avoiding damage to the surface of the auxiliary beam or stress concentration; on the other hand, the design of the support bar 412 and the groove 412a in the cavity can evenly distribute the adsorption force, increase the contact area between the suction cup 41 and the auxiliary beam, and improve the uniformity and stability of the adsorption force; in addition, air conduction is achieved through the groove 412a, which further enhances the negative pressure adsorption effect of the suction cup 41 and improves the positioning stability of the auxiliary beam.

[0063] The high load-bearing capacity of the polyurethane material enables the support bar 412 to firmly support the auxiliary beam and prevent the auxiliary beam from sliding and deforming during the installation process; the polyurethane material is soft and has a certain elasticity, and will not cause damage to the surface of the auxiliary beam during the support process, thereby protecting the structural integrity of the auxiliary beam.

[0064] Among them, a cross bar 21 is horizontally provided on the bracket 2, and a guide column 22, a first driving member 24 and a screw lift 23 are vertically provided between the cross bar 21 and the base 1. The first driving member 24 drives the screw lift 23 to rotate, and brings the guide column 22 to perform lifting and lowering movements, thereby pushing the cross bar 21 to perform lifting and lowering movements, and then driving the hard support component 3 and the soft support component 4 on the cross bar 21 to perform lifting and lowering movements synchronously, avoiding the position offset of the auxiliary beam caused by uneven lifting and lowering, improving the accuracy of auxiliary beam positioning, accelerating the positioning and bonding process of the auxiliary beam, and improving the overall installation efficiency; the design of the screw lift 23 and the first driving member 24 enables the entire lifting process to be completed through automatic control, reducing manual intervention, and improving the convenience and efficiency of operation; through the precise control of the screw lift 23, the height of the auxiliary beam can be adjusted to ensure that the auxiliary beam can accurately enter the auxiliary beam groove, simplifying the operation process.

[0065] In this embodiment, it also includes a second driving member 33 for driving the hard support component 3 to perform lifting motion and a third driving member 43 for driving the soft support component 4 to perform lifting motion. In this embodiment, the second driving member 33 is a guide rod cylinder, and the third driving member 43 is a lifting cylinder. The hard support component 3 and the soft support component 4 are independently driven by the guide rod cylinder and the cylinder respectively, which can achieve precise lifting motion and ensure that the auxiliary beam can be accurately positioned during the installation process; the second driving member 33 and the third driving member 43 can also be oil cylinders or other liftable mechanical structures, such as rack and pinion transmission, which are all within the protection scope of this application.

[0066] The present invention also includes a working method of the modular wind turbine blade lower auxiliary beam positioning and bonding device as described above, such as Figures 10 to 14 As shown, including:

[0067] S10: Fig.10 As shown, the lower auxiliary beam 015b is placed on the support module 100, and the lower auxiliary beam 015b is supported by the hard support component 3 and the soft support component 4; in this step, the lower auxiliary beam 015b is hoisted on the support module 100, so that the lower auxiliary beam 015b is in a horizontal state, in preparation for the next step of lifting;

[0068] S20: Fig.11 As shown, the lower auxiliary beam 015b is lifted to the bottom of the lower auxiliary beam groove of the blade skeleton 01, the hard support component 3 is lowered, and the bracket 2 is raised to drive the soft support component 4 to drive the lower auxiliary beam 015b into the lower auxiliary beam groove; specifically, since the width of the hard support component 3 and the position of the limit columns 32 on both sides of the width are greater than the width of the lower auxiliary beam groove, the hard support component 3 is lowered to avoid, so that the soft support component 4 can drive the lower auxiliary beam 015b into the lower auxiliary beam groove;

[0069] S30: Fig.12 As shown, the position and angle of the lower auxiliary beam 015b in the auxiliary beam groove are adjusted by the fine-tuning component 42, so that the outer contour of the auxiliary beam and the outer contour of the blade skeleton 01 are smoothly transitioned; specifically, the first driving member 24 is started to drive the bracket 2 to rise, thereby driving the lower auxiliary beam 015b to rise as a whole into the lower auxiliary beam groove. At this time, due to the placement error of the blade skeleton 01 or the processing error of the lower auxiliary beam groove, the lower auxiliary beam 015b is not at the center of the lower auxiliary beam groove, so the fine-tuning component 42 is used to make the position and angle of the lower auxiliary beam 015b in the lower auxiliary beam groove adapt to each other, so that the lower auxiliary beam 015b and the outer shape of the blade skeleton 01 adapt to each other;

[0070] S40: Fig.13As shown, after the adjustment is completed, the bracket 2 descends to lower the lower auxiliary beam 015b to the laying position according to the set stroke, and the guide fiber cloth 015c is laid on the upper surface and side wall of the lower auxiliary beam 015b; specifically, the guide fiber cloth 015c plays a role in guiding the resin, ensuring that the resin is evenly distributed and better bonding between the auxiliary beam and the auxiliary beam groove, thereby improving the bonding effect and quality;

[0071] S50: Fig.14 As shown, it rises according to the set stroke until it is bonded to the groove of the lower auxiliary beam, and the soft support component 4 is controlled to descend by groups to complete the laying of the auxiliary beam vacuum bag mold step by step; since the width of the auxiliary beam is relatively narrow, the surface laying of the reinforcing cloth and the vacuum bagging need to be integrated, and the soft support component 4 is controlled to descend by groups to make room for operation, that is, part of the soft support component 4 is first lowered near the vacuum bag mold to facilitate the laying of the vacuum bag mold in this section, and the soft support component 4 in the rear section still supports the lower auxiliary beam 015b. This step ensures the accurate laying of the vacuum bag mold, can provide sufficient support for the subsequent lower auxiliary beam 015b, and prevents the lower auxiliary beam 015b from loosening under the action of gravity before it is dried, which can shorten the waiting period and improve the bonding strength and quality;

[0072] S60: The auxiliary beam and the blade skeleton 01 are bonded into a whole by vacuum infusion. This step ensures the firm bonding of the auxiliary beam and the blade skeleton 01. The vacuum infusion technology is used to improve the bonding strength and quality, thereby ensuring the integrity and reliability of the structure.

[0073] As a preferred embodiment of the above embodiment, in step S30, the chord-wise adjustment component 422 is first used to adjust the chord-wise direction of the suction cup 41 to the center position of the lower auxiliary beam groove. This step ensures the position accuracy of the lower auxiliary beam 015b during the initial installation, avoids position deviation in subsequent steps, and improves the accuracy of the overall installation; then the angle adjustment component 421 is used to fine-tune the inclination angle of the suction cup 41 so that the outer contour of the auxiliary beam and the outer contour of the blade skeleton 01 smoothly transition. This step can correct the error caused by the mismatch of the inclination angle during the installation process, ensure the close fit between the auxiliary beam and the blade skeleton 01, and optimize the smoothness and consistency of the structural shape; it can improve the installation accuracy and bonding quality of the lower auxiliary beam 015b, optimize the shape transition of the wind turbine blade, enhance the stability and reliability of the overall structure, and at the same time improve the installation efficiency and safety.

[0074] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
