Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation technology, specifically a wind turbine blade transportation and carrying device. Background Technology

[0002] Wind turbine blades are one of the core components of a wind turbine, accounting for approximately 15-20% of the total cost. Their design directly affects wind energy conversion efficiency and annual power generation, making them a crucial element in wind energy utilization. Transport vehicles are used during the transportation of wind turbine blades.

[0003] A search revealed patent number CN217300772U, entitled "A Wind Turbine Blade Transport and Support Device." The device includes a support frame body with a lifting buckle at the top. An opening / closing rod is located on one side of the support frame body, with a drive rack along its length and an adjusting gear at one end. The support frame body has a first drive assembly and a second drive assembly. The first drive assembly meshes with the adjusting gear, and the second drive assembly meshes with the drive rack. By designating one side of the support frame body as the opening / closing rod, the first drive assembly drives the rod to engage and lock it, while the second drive assembly drives it to rise and fall to close. During use, the operator simply places the support frame body on one side of the blade, opens the rod, and pushes the support frame body under the blade. The operation is simple and convenient. However, research and analysis revealed that while it can support wind turbine blades, it still has the following drawbacks to some extent.

[0004] For example, once a wind turbine blade is placed, its angle cannot be adjusted, and it can only be transported in a fixed posture. When the angle of the wind turbine blade needs to be adjusted during subsequent transportation, it cannot be done effectively, which is detrimental to the transportation of wind turbine blades. To solve the above technical problems, we have designed a wind turbine blade transportation and carrying device. Utility Model Content

[0005] The purpose of this utility model is to provide a wind turbine blade transport and support device, which has the advantage of adjusting the tilt angle of the wind turbine blade. This solves the problem that after the wind turbine blade is placed, its angle cannot be adjusted and it can only be transported in a fixed posture. When the angle of the wind turbine blade needs to be adjusted during subsequent transportation, it cannot be effectively completed, which is not conducive to the transportation of wind turbine blades.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade transport and support device, comprising a base plate, with support plates connected to the left and right sides of the top of the base plate, support blocks connected to the top of the two support plates on opposite sides, vertical plates connected to the top of the support blocks, a rotating plate slidably mounted on the top of the two vertical plates, an installation block connected to the top of the right vertical plate, a T-shaped positioning shaft mounted on the right side of the top of the rotating plate, the bottom of the T-shaped positioning shaft penetrating the rotating plate and connected to the installation block, a lower arc-shaped plate connected to the top of the base plate and between the two support plates, an upper arc-shaped plate connected to the bottom of the rotating plate and above the lower arc-shaped plate, a lower arc-shaped groove formed on the inner wall of the lower arc-shaped plate, an upper arc-shaped groove formed on the inner wall of the upper arc-shaped plate, and a load-bearing component installed inside the lower arc-shaped groove and the upper arc-shaped groove.

[0007] Preferably, positioning blocks are connected to both the left and right sides of the base plate, and positioning holes are provided through the top of the positioning blocks. A rotating hole for use with a T-shaped positioning shaft is provided through the right side of the top of the rotating plate, and the inner wall of the rotating hole is in sliding contact with the outer side of the T-shaped positioning shaft.

[0008] Preferably, positioning screw holes are provided on both the front and rear sides of the top of the left vertical plate, and positioning bolts are provided on both the front and rear sides of the top left side of the rotating plate. The bottom of the positioning bolts penetrates the rotating plate and extends into the interior of the positioning screw holes, where they are threadedly connected to the inner wall of the positioning screw holes.

[0009] Preferably, the rotating plate has rotating holes on both the front and rear sides of the top left side, the inner wall of the rotating hole slides in contact with the outside of the positioning bolt, and an elastic washer is fitted on the top of the positioning bolt and placed on the top of the rotating plate.

[0010] Preferably, the bearing component includes two semi-circular guide rings, which are located inside the lower arc-shaped groove and the upper arc-shaped groove, respectively. The two ends of the two semi-circular guide rings are connected to the two ends of the inner walls of the lower arc-shaped groove and the upper arc-shaped groove, respectively. A linear motor is sleeved on the outside of the semi-circular guide rings.

[0011] Preferably, each of the two linear motors is connected to an electric telescopic rod on one of their opposite sides. The telescopic ends of the electric telescopic rods are connected to connecting blocks. Each of the two connecting blocks is connected to a bearing plate on one of their opposite sides. Each of the two bearing plates is provided with a bearing groove on one of their opposite sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the combined use of a lower arc-shaped plate, a bearing component, a lower arc-shaped groove, a support plate, an upper arc-shaped plate, a rotating plate, and an upper arc-shaped groove to adjust the tilt angle of wind turbine blades. The telescopic end of the upper electric telescopic rod extends, allowing the top bearing plate to rest on top of the bottom bearing plate.

[0015] Please see Figures 1-4 A wind turbine blade transport and support device includes a base plate 1. Support plates 5 are connected to the left and right sides of the top of the base plate 1. Support blocks 13 are connected to the top of the two support plates 5 on the side furthest from each other. Vertical plates 12 are connected to the top of the support blocks 13. A rotating plate 11 is slidably mounted on the top of the two vertical plates 12. An installation block 7 is connected to the top of the right vertical plate 12. A T-shaped positioning shaft 8 is provided on the right side of the top of the rotating plate 11. The bottom of the T-shaped positioning shaft 8 passes through the rotating plate 11 and is connected to the installation block 7. A lower arc plate 2 is connected to the top of the base plate 1 and between the two support plates 5. An upper arc plate 9 is connected to the bottom of the rotating plate 11 and above the lower arc plate 2. A lower arc groove 4 is formed on the inner wall of the lower arc plate 2. An upper arc groove 16 is formed on the inner wall of the upper arc plate 9. A load-bearing component 3 is installed inside the lower arc groove 4 and the upper arc groove 16.

[0016] Positioning blocks 6 are connected to both the left and right sides of the base plate 1. Positioning holes are opened through the top of the positioning blocks 6. Rotating holes are opened through the right side of the top of the rotating plate 11 to cooperate with the T-shaped positioning shaft 8. The inner wall of the rotating hole slides in contact with the outer side of the T-shaped positioning shaft 8. The base plate 1 is conveniently positioned and installed on the transport platform by bolts through the cooperation of the positioning blocks 6 and the positioning holes. The rotation of the rotating plate 11 is convenient through the cooperation of the T-shaped positioning shaft 8 and the rotating holes.

[0017] The top of the left vertical plate 12 has positioning screw holes 14 on both the front and back sides. The top of the left side of the rotating plate 11 has positioning bolts 10 on both the front and back sides. The bottom of the positioning bolts 10 passes through the rotating plate 11 and extends into the interior of the positioning screw holes 14, where they are threaded to the inner wall of the positioning screw holes 14. The positioning screw holes 14 and the positioning bolts 10 work together to facilitate the positioning of the rotating plate 11 and prevent the rotating plate 11 from rotating arbitrarily on the top of the vertical plate 12.

[0018] Rotating holes are provided on both the front and rear sides of the top left side of the rotating plate 11. The inner wall of the rotating hole slides in contact with the outside of the positioning bolt 10. An elastic washer 15 is fitted on the top of the positioning bolt 10. The elastic washer 15 is placed on the top of the rotating plate 11. The rotating holes facilitate the rotation of the positioning bolt 10. The use of the elastic washer 15 has the following advantages: Anti-loosening function: After the elastic washer 15 is flattened, it generates continuous elastic force, increases the friction between it and the positioning bolt 10, forms a resistance torque, and resists loosening caused by vibration or impact; Compensation for preload loss: When the preload of the positioning bolt 10 decreases due to temperature changes, creep, or settlement, the elasticity of the elastic washer 15 can partially compensate for the pressure loss and maintain the connection stability.

[0019] The supporting component 3 includes two semi-circular guide rings 33, which are located inside the lower arc groove 4 and the upper arc groove 16, respectively. The two ends of the two semi-circular guide rings 33 are connected to the two ends of the inner walls of the lower arc groove 4 and the upper arc groove 16, respectively. A linear motor 35 is sleeved on the outside of the semi-circular guide rings 33. The cooperation between the lower arc groove 4 and the upper arc groove 16 facilitates the concealed installation of the semi-circular guide rings 33.

[0020] Two linear motors 35 are each connected to an electric telescopic rod 34 on one side opposite to each other. The telescopic ends of the electric telescopic rods 34 are connected to connecting blocks 36. Each of the two connecting blocks 36 is connected to a bearing plate 31 on one side opposite to each other. Each of the two bearing plates 31 is provided with a bearing groove 32 on one side opposite to each other. The blades of the wind turbine can be placed by the cooperation of the upper and lower bearing grooves 32.

[0021] In use, the wind turbine blades are transferred to the lower bearing groove 32 using external equipment, and the rotating plate 11 is pushed to rotate around the T-shaped positioning shaft 8, so that the rotating plate 11 is eventually placed horizontally. An elastic washer 15 is fitted onto the positioning bolt 10, and then the positioning bolt 10 is inserted into the rotating hole and rotated to complete the threaded connection with the positioning screw hole 14. Finally, the positioning bolt 10 presses against the elastic washer 15 to complete the positioning of the rotating plate 11. At this time, the upper arc plate 9 is located on top of the lower arc plate 2.

[0022] The external control terminal of the transport and support device controls the extension of the upper electric telescopic rod 34, allowing the top support plate 31 to rest on top of the bottom support plate 31. The upper support groove 32 engages with the outside of the wind turbine blade, thus securing and supporting the wind turbine blade. If the tilt angle of the wind turbine blade needs to be changed, the two linear motors 35 are controlled to rotate outside the semi-circular guide ring 33, causing the two electric telescopic rods 34 and the two support plates 31 to rotate accordingly, thereby changing the angle of the wind turbine blade. Further extension and retraction of the two electric telescopic rods 34 can change the vertical position of the wind turbine blade.

[0023] In summary, this wind turbine blade transport and support device, through the coordinated use of the lower arc plate 2, the support component 3, the lower arc groove 4, the support plate 5, the upper arc plate 9, the rotating plate 11, and the upper arc groove 16, solves the problem that after the wind turbine blade is placed, its angle cannot be adjusted, and it can only be transported in a fixed posture. When the angle of the wind turbine blade needs to be adjusted during subsequent transportation, it cannot be effectively completed, which is detrimental to the transportation of wind turbine blades.
