Abstract
Description
Technical Field
[0001] This utility model relates to the field of support frame technology, and more specifically, it relates to a highly stable support frame for transporting wind turbine blades. Background Technology
[0002] While existing wind turbine blade transport support frames can generally support and secure the blades, they suffer from several drawbacks. First, the support height is difficult to adjust. Most current support frames are fixed structures, unable to flexibly adjust the support height according to different models, lengths, or curvatures of wind turbine blades. This leads to an uneven distribution of the blade's center of gravity during transport, resulting in uneven stress, increased vibration, and a higher risk of damage. Furthermore, the lack of height adjustment makes it difficult for the support frames to accommodate blades of various specifications and sizes, reducing versatility and reusability.
[0003] Secondly, the binding position is inconvenient to adjust. Traditional support frames often use fixed binding points for blade binding, making it impossible to flexibly adjust the binding position according to the structural characteristics and stress points of the blade. This not only affects the stability of the binding, but may also cause scratches on the blade surface or local stress concentration during transportation due to improper positioning, damaging the blade structure. In addition, adjusting the binding position usually requires disassembling and rearranging the binding components, which is a cumbersome and time-consuming process, seriously affecting transportation efficiency and operational safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a support frame for transporting wind turbine blades with high stability, comprising a base plate, a rope seat, a lifting mechanism, a binding position locking mechanism, and a locking auxiliary mechanism. The lifting mechanism includes an adjusting seat and a lifting frame. The adjusting seat is symmetrically installed at the top end of the base. The adjusting seat is provided with a threaded rod, and a threaded block is threadedly connected to the threaded rod. The bottom end of the lifting frame is connected to the threaded block. A top roller is installed at the top end of the lifting frame, and two sets of top rollers are provided. The external blades are placed on the top rollers. The binding position locking mechanism includes a locking tube and a locking rod. A locking groove is opened on the side wall of the locking rod. A rotating plate is rotatably installed on the side wall of the locking tube. An embedded block is installed at one end of the rotating plate. A directional sleeve is slidably installed on the outer wall of the locking tube. The directional plate presses against the side of the rotating plate, so that the embedded block extends into the locking groove in the side wall of the locking rod, so that the locking rod is relatively fixed in the locking tube.
[0008] The present invention is further configured such that the snap-fit auxiliary mechanism includes an outer rotating ring and a spring-loaded pin. The outer rotating ring is rotatably mounted on the outer wall of the snap-fit tube. A spring-loaded groove is provided on the top end of the outer rotating ring, and multiple sets of spring-loaded grooves are provided. An outer retaining ring is fixedly installed on the outer wall of the snap-fit tube, and multiple sets of spring-loaded pins are installed on the outer retaining ring. The spring-loaded pins push against the spring-loaded grooves step by step, so that the outer rotating ring rotates stably. A spiral plate is installed on the bottom end of the outer rotating ring, and a spiral groove is provided on the side wall of the directional sleeve. The spiral groove and the spiral plate are screw-slidably connected.
[0009] The present invention is further configured such that side plates are installed on both sides of the rope seat, and the clamping tube is fixedly installed on the side plates. The side plates enhance the structural strength of the rope seat and provide an installation platform for the clamping tube.
[0010] The present invention is further configured such that the base plate is symmetrically provided with adjustment holes, and multiple sets of adjustment holes are provided. One end of the locking rod can pass through different adjustment holes and engage with the locking tube. The multiple sets of adjustment holes provide multiple binding position options, and the position of the rope seat can be flexibly adjusted according to different sizes of blades, thereby enhancing adaptability.
[0011] The present invention is further configured such that the rope seat is provided in two sets, and a binding rope is provided between the two sets of rope seats. The binding rope binds the blade to the top end of the lifting frame. The binding rope connects the two sets of rope seats and firmly binds the blade to the top of the lifting frame to prevent the blade from moving or vibrating during transportation.
[0012] The present invention is further configured such that a directional rail is installed at the top end of the adjusting seat, and the threaded block is slidably guided on the directional rail. The directional rail provides sliding guidance for the threaded block to prevent shaking during the lifting process and ensure the accuracy of vertical movement.
[0013] The present invention is further configured such that the threaded rod limiting support is rotatably mounted on the adjusting seat, one end of the threaded rod is connected to an external drive device, and the threaded rod achieves precise height adjustment by rotation, while the other end is connected to an external drive device for easy operation.
[0014] The present invention is further configured such that a base is installed at the bottom end of the base plate, and the base is installed around the bottom end of the base plate. The base increases the contact area between the support frame and the transport platform, thereby improving the overall stability.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a highly stable support frame for transporting wind turbine blades, which has the following advantages:
[0017] This utility model is equipped with a lifting and jacking mechanism. Through the threaded connection design of the adjusting seat and the jacking frame, precise height adjustment is allowed. This not only ensures that the blade is placed stably during transportation, avoiding structural damage caused by uneven support or unsuitable height, but also improves the versatility of the support frame, which can adapt to wind turbine blades of different sizes or curvatures. The top roller and two sets of support configurations at the top of the jacking frame ensure that the blade is placed stably on the support frame, effectively distributing the weight of the blade and reducing the impact of external forces on the blade during transportation.
[0018] This utility model features a binding position locking mechanism with an adjustable locking rod and locking tube, allowing for flexible adjustment of the binding point and ensuring the stable fixation of the wind turbine blade during transportation. The engagement of the locking groove and the insert block ensures a secure connection between the locking rod and the locking tube, preventing loosening or displacement during binding. By adjusting the binding point position, the binding position can be adjusted according to the different shapes or stress characteristics of the blade, avoiding damage to the blade surface or stress concentration caused by improper positioning.
[0019] This utility model is equipped with a snap-fit auxiliary mechanism. Through the combination design of the outer rotating ring and the spring-loaded pin, the stability and flexibility of the snap-fit mechanism are enhanced. The outer rotating ring can rotate stably under the action of the spring-loaded pin, making the snap-fit mechanism more accurate when adjusting the binding position and avoiding instability caused by improper adjustment. At the same time, the cooperation between the spiral plate and the directional sleeve further ensures the stability of the snap-fit tube and prevents loosening or displacement during transportation, thus further ensuring the safe transportation of the blade.

[0029] Please see Figures 1-5A highly stable support frame for transporting wind turbine blades includes a base plate 1, a rope seat 2, a lifting and jacking mechanism, a binding position locking mechanism, and a locking auxiliary mechanism. The lifting and jacking mechanism includes an adjusting seat 3 and a jacking frame 4. The adjusting seat 3 is symmetrically installed on the top end of the base 24. The adjusting seat 3 is provided with a threaded rod 5, and a threaded block 6 is threadedly connected to the threaded rod 5. The bottom end of the jacking frame 4 is connected to the threaded block 6. A top roller 7 is installed on the top end of the jacking frame 4, and the top roller 7 is provided with two... The outer blade is placed on the top roller 7. The binding position locking mechanism includes a locking tube 8 and a locking rod 9. The locking rod 9 has a locking groove 10 on its side wall. A rotating plate 11 is rotatably installed on the side wall of the locking tube 8. An embedded block 12 is installed at one end of the rotating plate 11. A directional sleeve 13 is directionally slidably installed on the outer wall of the locking tube 8. The directional plate presses against the side of the rotating plate 11, so that the embedded block 12 extends into the locking groove in the side wall of the locking rod 9, so that the locking rod 9 is relatively fixed in the locking tube 8.
[0030] In this embodiment, precise lifting and lowering of the blade is achieved through a screw drive. An external drive device is connected to the end of the threaded rod 5, causing the threaded rod 5 to rotate within the adjusting seat 3. Since the threaded rod 5 is threadedly connected to the threaded block 6, the rotation of the threaded rod 5 is converted into the vertical linear motion of the threaded block 6. The threaded block 6 is connected to the bottom of the lifting frame 4, causing the lifting frame 4 and its two sets of top rollers 7 to move up and down synchronously. At the same time, the threaded block 6 slides on the directional rail 23, ensuring that the entire lifting process is stable and straight, achieving precise adjustment of the blade height, which facilitates subsequent binding and fixing operations. The snap-fit mechanism ensures precise fixation of the binding position. The snap-fit rod 9 passes through the adjustment holes 21 at different positions on the base plate 1 and is inserted into the snap-fit tube 8 fixed on the side plate 20 of the rope seat 2. The rotating plate 11 on the side wall of the snap-fit tube 8 rotates, causing the insert block 12 at its end to extend into the snap-fit groove 10 on the side wall of the snap-fit rod 9. The directional sleeve 13 on the outer wall of the snap-fit tube 8 slides downward and presses against the side of the rotating plate 11, enhancing the locking force between the insert block 12 and the snap-fit groove 10, thereby firmly fixing the snap-fit rod 9 in the snap-fit tube 8, ensuring the stability of the rope seat 2 and providing a reliable binding point for the blade.
[0031] The locking auxiliary mechanism includes an outer rotating ring 14 and a spring-loaded pin 15. The outer rotating ring 14 is rotatably mounted on the outer wall of the locking tube 8. A spring-loaded groove 16 is provided on the top end of the outer rotating ring 14. Multiple sets of spring-loaded grooves 16 are provided. An outer retaining ring 17 is fixedly installed on the outer wall of the locking tube 8. Multiple sets of spring-loaded pins 15 are installed on the outer retaining ring 17. The spring-loaded pins 15 push against the spring-loaded grooves 16 in stages, so that the outer rotating ring 14 rotates stably. A spiral plate 18 is installed on the bottom end of the outer rotating ring 14. A spiral groove 19 is provided on the side wall of the directional sleeve 13. The spiral groove 19 and the spiral plate 18 are connected in a spiral sliding connection.
[0032] In this embodiment, the locking effect is enhanced by precisely controlling the movement of the directional sleeve 13. The outer rotating ring 14 is mounted on the outer wall of the locking tube 8 for limiting rotation. The spiral plate 18 at its bottom cooperates with the spiral groove 19 on the side wall of the directional sleeve 13. When the outer rotating ring 14 is rotated, the meshing of the spiral plate 18 and the spiral groove 19 converts the rotational motion into the longitudinal movement of the directional sleeve 13, precisely controlling the pressure of the directional sleeve 13 on the rotating plate 11. At the same time, multiple sets of spring-loaded pins 15 are installed on the outer retaining ring 17 fixed on the outer wall of the locking tube 8. These spring-loaded pins 15 push against the spring-loaded groove 16 at the top of the outer rotating ring 14 in stages, providing a graded positioning function to ensure the stability and controllability of the rotation of the outer rotating ring 14.
[0033] Please see Figures 1-5 As a supplementary embodiment of a highly stable support frame for transporting wind turbine blades, which includes a lifting mechanism, a binding position locking mechanism, and a locking auxiliary mechanism: Side plates 20 are installed on both sides of the rope seat 2, and locking tubes 8 are fixedly installed on the side plates 20. Adjustment holes 21 are symmetrically opened on the base plate 1. Multiple sets of adjustment holes 21 are provided. One end of the locking rod 9 can pass through different adjustment holes 21 and engage with the locking tube 8. There are two sets of rope seats 2, and a binding rope 22 is connected between the two sets of rope seats 2. The binding rope 22 binds the blade to the top end of the lifting frame 4. A directional rail 23 is installed on the top end of the adjustment seat 3. A threaded block 6 is slidably guided on the directional rail 23. A threaded rod 5 is rotatably mounted on the adjustment seat 3 with a limiting support. One end of the threaded rod 5 is connected to an external drive. A base 24 is installed on the bottom end of the base plate 1, and the base 24 is installed around the bottom end of the base plate 1.
[0034] More specifically, the base plate 1 is securely placed on the transport platform via the base 24. The positions of the two sets of rope seats 2 are adjusted according to the size of the blade. A suitable adjustment hole 21 is selected on the base plate 1, and the locking rod 9 is inserted into the locking tube 8 through the adjustment hole 21. The locking rod 9 is locked by the rotating plate 11 and the embedded block 12. The outer rotating ring 14 is rotated, and the directional sleeve 13 is moved and pressed against the rotating plate 11 by the cooperation of the spiral plate 18 and the spiral groove 19, which strengthens the locking effect. The cooperation of the spring top pin 15 and the spring top groove 16 provides graded positioning feedback, drives the threaded rod 5 to rotate, and drives the lifting frame 4 to rise to an appropriate height through the threaded block 6. The blade is placed on the two sets of top rollers 7, and the blade is securely tied to the top of the lifting frame 4 by the binding rope 22 between the two sets of rope seats 2, forming a stable transport state. If necessary, the blade height can be finely adjusted by rotating the threaded rod 5 to ensure stability during transport.
[0035] In summary, during use or operation of the overall equipment: when the lifting mechanism needs to be raised or lowered, the propeller is precisely raised or lowered through a screw drive. The external drive device is connected to the end of the threaded rod 5, which drives the threaded rod 5 to rotate within the adjusting seat 3. Since the threaded rod 5 is threadedly connected to the threaded block 6, the rotation of the threaded rod 5 is converted into the vertical linear motion of the threaded block 6. The threaded block 6 is connected to the bottom of the lifting frame 4, which drives the lifting frame 4 and the two sets of top rollers 7 at its top to move up and down synchronously. At the same time, the threaded block 6 slides on the directional rail 23, ensuring that the entire lifting process is stable and straight, achieving precise adjustment of the propeller height, which facilitates subsequent binding and fixing operations.
[0036] When the binding position locking mechanism is in operation, it ensures the precise fixing of the binding position. The locking rod 9 passes through the adjustment holes 21 at different positions on the base plate 1 and is inserted into the locking tube 8 fixed on the side plate 20 of the rope seat 2. The rotating plate 11 on the side wall of the locking tube 8 rotates, so that the embedding block 12 at its end extends into the locking groove 10 on the side wall of the locking rod 9. The directional sleeve 13 on the outer wall of the locking tube 8 slides down and presses against the side of the rotating plate 11, enhancing the locking force between the embedding block 12 and the locking groove 10, thereby firmly fixing the locking rod 9 in the locking tube 8, ensuring the stability of the rope seat 2 and providing a reliable binding point for the blade.
[0037] When the locking auxiliary mechanism is in operation, the locking effect is enhanced by precisely controlling the movement of the directional sleeve 13. The outer rotating ring 14 is mounted on the outer wall of the locking tube 8 for limiting rotation. The spiral plate 18 at its bottom cooperates with the spiral groove 19 on the side wall of the directional sleeve 13. When the outer rotating ring 14 is rotated, the meshing of the spiral plate 18 and the spiral groove 19 converts the rotational motion into the longitudinal movement of the directional sleeve 13, precisely controlling the pressure of the directional sleeve 13 on the rotating plate 11. At the same time, multiple sets of spring-loaded pins 15 are installed on the outer fixed ring 17 fixed on the outer wall of the locking tube 8. These spring-loaded pins 15 push against the spring-loaded groove 16 at the top of the outer rotating ring 14 in stages, providing a graded positioning function to ensure the stability and controllability of the rotation of the outer rotating ring 14.
[0038] The base plate 1 is securely placed on the transport platform via the base 24. The positions of the two sets of rope seats 2 are adjusted according to the size of the blade. A suitable adjustment hole 21 is selected on the base plate 1. The locking rod 9 is inserted into the locking tube 8 through the adjustment hole 21. The locking rod 9 is locked by the rotating plate 11 and the embedded block 12. The outer rotating ring 14 is rotated. The directional sleeve 13 is moved and pressed against the rotating plate 11 by the cooperation of the spiral plate 18 and the spiral groove 19, which strengthens the locking effect. The cooperation of the spring top pin 15 and the spring top groove 16 provides graded positioning feedback, drives the threaded rod 5 to rotate, and drives the lifting frame 4 to rise to an appropriate height through the threaded block 6. The blade is placed on the two sets of top rollers 7. The binding rope 22 between the two sets of rope seats 2 is used to firmly bind the blade to the top of the lifting frame 4, forming a stable transport state. If necessary, the blade height can be finely adjusted by rotating the threaded rod 5 to ensure stability during transport.
