Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation and fixing technology, and more specifically, it relates to a height-adjustable wind turbine blade transportation and fixing device. Background Technology

[0002] With the booming development of the renewable energy industry, the trend of wind power equipment becoming larger is becoming increasingly apparent. As the core component of wind turbines, the safe and efficient transportation of wind turbine blades has become a key link in the wind power industry chain, which has a decisive impact on the construction progress and cost control of wind farms.

[0003] In existing technology, wind turbine blades have a circular end and a flat end. While this special structural design is beneficial for wind energy capture, it brings many difficulties during transportation. Traditional blade transportation and fixing devices are mainly designed for the circular structure and are difficult to adapt to the flat end, resulting in insecure fixing. This makes the blades prone to shaking and displacement during transportation, increasing the risk of blade damage. This is especially true in complex road conditions and severe weather conditions, where the safety hazards are more prominent.

[0004] To meet the needs of mountain wind farm construction, transportation equipment has higher requirements for the flexibility of height adjustment. In mountainous areas with complex terrain and narrow, winding roads, wind turbine blade transportation faces many obstacles and height-restricted bridges. Traditional fixed equipment cannot achieve precise height adjustment, which often prevents the blades from passing through key nodes such as tunnels and bridges smoothly. In some cases, large-scale road reconstruction is even required, which greatly increases the project cost and time cycle. Utility Model Content

[0011] The present invention is further configured such that guide plates are fixedly provided on the outer walls of multiple sets of slide rods, and the multiple sets of guide plates are slidably connected to multiple sets of limiting cylinders to ensure the stability of the slide rods during movement and avoid uneven clamping or damage to the equipment due to deviation.

[0012] The present invention is further configured such that the inner sides of the multiple sets of abutment blocks are all arc-shaped, which can provide a better contact surface, making the clamping process more uniform and stable, and reducing the pressure concentration on the wind turbine blades.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a height-adjustable wind turbine blade transportation and fixing device, which has the following advantages:

[0018] 1. This device, by setting up multiple sets of adapter mechanisms, can flexibly adjust to wind turbine blades of different specifications and sizes. The adapter mechanism adopts a sliding connection structure of mounting sleeve and inner ring. The mounting sleeve is moved by the cylinder, so that the rubber block on the clamping block can reliably clamp the wind turbine blade and avoid damage to the blade surface. At the same time, the clamping and resetting can be quickly switched through the cooperation of sliding rod, limit cylinder and reset spring. The whole clamping process is efficient, convenient and highly adaptable.

[0019] 2. This device is equipped with a reasonably structured limiting mechanism. Through the cooperation of the limiting rod, rotating sleeve, longitudinal rod and limiting hole, the limiting sleeve can be precisely locked. During the clamping process, the pressure ring pushes the inclined block and the abutment block to ensure the stability of the slide rod in the clamped state, prevent the clamping block from loosening or shifting during transportation, improve clamping safety and transportation reliability. At the same time, the unlocking process is simple, and the clamping state can be quickly released by rotating the operation.

[0020] 3. This device is equipped with a height-adjustable lifting mechanism. The motor drives the screw to rotate, which in turn moves the transmission block, thereby adjusting the height of the support rod and realizing the overall lifting of the fixed plate and the support plate. With the support wheels, it can effectively support the round end of the wind turbine blade, meeting the different height requirements of different transport vehicles or transport conditions. The cooperation between the guide frame and the guide wheels ensures smooth movement during the lifting process, further improving the applicability and stability of the equipment in actual transport operations.

[0030] Please see Figures 1-5A height-adjustable wind turbine blade transport and fixing device includes a fixing plate 1. Multiple sets of adapter mechanisms are provided on the fixing plate 1. Each adapter mechanism includes a mounting sleeve 2 and an inner ring 3. The mounting sleeve 2 slides within the fixing plate 1, and the inner ring 3 is fixed to the inner wall of the mounting sleeve 2. A limiting cylinder 4 is fixed to the top of the mounting sleeve 2. Multiple sets of limiting cylinders 4 are provided, each with a sliding rod 5 slidably mounted on its inner side. Each set of sliding rods 5 is slidably connected to the inner ring 3, and each set has a connecting plate 6 fixed to its bottom end. Each set of connecting plates 6 is connected to the outer wall of the inner ring 3. A reset spring 7 is provided. Clamping blocks 8 are fixedly provided at the top of multiple sets of sliding rods 5. An inclined groove 9 is provided on the inner wall of the mounting sleeve 2. An inclined block 10 is slidably provided in multiple sets of inclined grooves 9. An abutment block 11 is fixedly provided on the inner side of each set of inclined blocks 10. A sliding groove 12 is provided on the outer wall of the mounting sleeve 2. A limiting sleeve 13 is slidably provided in the sliding groove 12. A pressure ring 14 is fixedly provided on the inner side of the limiting sleeve 13. A cylinder 15 is fixedly provided on the outer side of the fixing plate 1. An cylinder 15 is provided in multiple sets, and the telescopic ends are respectively fixedly connected to multiple sets of mounting sleeves 2.

[0031] A limiting mechanism is provided on the outer side of the mounting sleeve 2. The limiting mechanism includes a limiting rod 16 and a rotating sleeve 17. Multiple sets of limiting rods 16 are provided and fixed to the outer wall of the limiting sleeve 13. A longitudinal rod 18 is fixed on the outer wall of the rotating sleeve 17. Multiple sets of longitudinal rods 18 are provided and each has a limiting hole 19 on its outer wall. By inserting the limiting rod 16 into the limiting hole 19 on the longitudinal rod 18, the rotating sleeve 17 is limited and positioned to prevent the mounting sleeve 2 from shifting or rotating during operation and to ensure the stability of the overall structure.

[0032] Each of the multiple clamping blocks 8 has a rubber block 20 fixed at its top. The rubber block 20 makes flexible contact with the clamped object, which plays a buffering and protective role, effectively avoiding damage to the workpiece surface due to hard contact, and improving the safety and stability of clamping.

[0033] Guide plates 21 are fixedly provided on the outer walls of multiple sets of slide rods 5. The multiple sets of guide plates 21 are slidably connected to multiple sets of limiting cylinders 4. Through the sliding cooperation between the guide plates 21 and the limiting cylinders 4, the slide rods 5 maintain a stable trajectory during movement, preventing them from tilting or shaking during movement and improving the movement accuracy of the structure.

[0034] The inner sides of the multiple sets of abutment blocks 11 are all set to be arc-shaped. The arc-shaped contact surface can better fit the shape of the round or arc-shaped workpiece, increase the contact area and friction, enhance the clamping stability, and at the same time reduce the local pressure on the workpiece and prevent damage.

[0035] In this embodiment, during use, the circular end of the wind turbine blade is placed on multiple sets of supporting rollers 29, and the flat end is placed inside multiple sets of adapter mechanisms. Multiple sets of cylinders 15 push multiple sets of mounting sleeves 2 to move, causing the rubber blocks 20 at the top of multiple sets of clamping blocks 8 to abut against the outer wall of the wind turbine blade. This causes multiple sets of sliding rods 5 to slide along the limiting cylinder 4 and inner ring 3, stretching the return spring 7. When all sets of rubber blocks 20 abut against the outer wall of the wind turbine blade, the limiting sleeve 13 is pushed to slide along multiple sets of sliding grooves 12 and pushes multiple sets of abutting blocks 11 through the pressure ring 14. This causes the multiple sets of abutting blocks 11 to slide along the inclined groove 9 via the inclined block 10, so that the inner sides of the multiple sets of abutting blocks 11 abut against the outer wall of the multiple sets of sliding rods 5. At this time, the multiple sets of clamping blocks 11... Positioning rod 16 is parallel to limiting hole 19. Rotating rotating sleeve 17 drives multiple sets of longitudinal rods 18 to rotate, so that multiple sets of limiting rods 16 are inserted into limiting hole 19 to restrict limiting sleeve 13. Multiple sets of abutment blocks 11 fix sliding rod 5 to complete the clamping of wind turbine blade. When unlocking is required, rotating rotating sleeve 17 causes multiple sets of longitudinal rods 18 to rotate, so that multiple sets of limiting rods 16 disengage from limiting hole 19, releasing the restriction on limiting sleeve 13, thereby releasing the pressure ring 14 from pressing multiple sets of abutment blocks 11, releasing the fixation of multiple sets of sliding rod 5. By releasing the clamping of wind turbine blade, the telescopic ends of multiple sets of cylinders 15 retract into mounting sleeve 2, and multiple sets of return springs 7 pull connecting plate 6 to drive multiple sets of sliding rod 5 to reset.

[0036] Please see Figures 1-2 As one implementation of the lifting mechanism: a base plate 22 is provided below the fixed plate 1, and multiple lifting mechanisms are provided on the base plate 22. The lifting mechanism includes a mounting base 23 and a transmission block 24. The mounting base 23 is fixed to the top surface of the base plate 22, and a motor 25 is fixedly installed inside the mounting base 23. A screw 26 is fixedly connected to the output end of the motor 25. The transmission block 24 is threadedly connected to the outer wall of the screw 26, and a support rod 27 is fixedly installed on the outer wall of the transmission block 24. A set of support rods 27 abuts against the bottom surface of the fixed plate 1. The motor 25 drives the screw 26 to rotate, causing the transmission block 24 to move up and down along the screw axis, thereby driving the support rods 27 to rise and fall, realizing the adjustment of the height of the fixed plate 1 and improving the adaptability of the device to different working conditions.

[0037] The lifting mechanism is equipped with a support plate 28, and a support wheel 29 is rotatably installed on the top surface of the support plate 28. The support wheel 29 is installed on the support plate 28 and can rotate with the object it contacts, reducing frictional resistance and playing the role of auxiliary support and movement guidance, which is conducive to the smooth movement or positioning of the workpiece during the support process.

[0038] A guide frame 30 is fixedly mounted on the mounting base 23. The guide frame 30 is rotatably connected to the top of the screw 26. A guide wheel 31 is rotatably mounted on the outer wall of the transmission block 24. Multiple guide wheels 31 are provided and abut against the outer wall of the guide frame 30. The guide wheels 31 cooperate with the guide frame 30 to restrict the rotational freedom of the transmission block 24, ensuring that it only performs linear lifting and lowering motion under the drive of the screw 26, thereby improving the stability and accuracy of lifting and lowering.

[0039] More specifically, the starting motor 25 drives the screw 26 to rotate. The screw 26 rotates and engages with the transmission block 24 through a threaded connection, causing the transmission sleeve to drive the support rod 27 to rise and fall. When the transmission block 24 moves, it is guided by multiple sets of guide wheels 31 moving along the outer wall of the guide frame 30. Thus, the height of the fixed plate 1 or the support plate 28 is adjusted by the lifting mechanism.

[0040] In summary, during use or operation of the overall equipment: In use, the circular end of the wind turbine blade is placed on multiple sets of support rollers 29, and the flat end is placed inside multiple sets of adapter mechanisms. Multiple sets of cylinders 15 push multiple sets of mounting sleeves 2 to move, causing the rubber blocks 20 at the top of multiple sets of clamping blocks 8 to abut against the outer wall of the wind turbine blade. This also causes multiple sets of sliding rods 5 to slide along the limiting cylinder 4 and inner ring 3, stretching the return spring 7. When all sets of rubber blocks 20 abut against the outer wall of the wind turbine blade, the limiting sleeve 13 is pushed to slide along multiple sets of sliding grooves 12, and the pressure ring 14 pushes multiple sets of abutting blocks 11, causing the multiple sets of abutting blocks 11 to slide along the inclined groove 9 via the inclined block 10. This allows the inner sides of the multiple sets of abutting blocks 11 to abut against the outer wall of the multiple sets of sliding rods 5. At this time, multiple sets of limiting rods 16 are parallel to the limiting holes 19. Rotating the rotating sleeve 17 drives multiple sets of longitudinal rods 18 to rotate, so that multiple sets of limiting rods 16 are inserted into the limiting holes 19 to restrict the limiting sleeve 13. Multiple sets of abutment blocks 11 fix the slide rod 5, thus completing the clamping of the wind turbine blade. When unlocking is required, rotating the rotating sleeve 17 causes multiple sets of longitudinal rods 18 to rotate, so that multiple sets of limiting rods 16 disengage from the limiting holes 19, releasing the restriction on the limiting sleeve 13, thereby releasing the pressure ring 14 from pressing the multiple sets of abutment blocks 11, releasing the fixation of multiple sets of slide rods 5. By releasing the clamping of the wind turbine blade, the telescopic ends of multiple sets of cylinders 15 retract the mounting sleeve 2, and multiple sets of return springs 7 pull the connecting plate 6 to drive the multiple sets of slide rods 5 to reset.

[0041] The starting motor 25 drives the screw 26 to rotate. The screw 26 rotates and engages with the transmission block 24 through a threaded connection, causing the transmission sleeve to drive the support rod 27 to rise and fall. When the transmission block 24 moves, it is guided by multiple sets of guide wheels 31 moving along the outer wall of the guide frame 30. Thus, the height of the fixed plate 1 or the support plate 28 is adjusted by the lifting mechanism.

These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.

[0043] In all the solutions mentioned above, the operation of electrical components, unless otherwise specified, is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and wiring connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here. The specific models and specifications of the electrical components involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, and therefore will not be described in detail.
