Description

Technical Field

[0001] This utility model relates to the technical field of wind turbines, and in particular to a wind turbine blade support. Background Technology

[0002] In the field of wind power technology, the use of support frames is indispensable in the processing and installation of wind turbine blades. While existing support frame designs can meet the need for height adjustment of the blades to facilitate processing under different operating conditions, this design has a significant drawback. When the support frame is raised, its overall center of gravity also shifts upwards. Due to this change in the center of gravity, the overall stability of the equipment decreases significantly during operation or processing, making it prone to tipping over. Once tipped over, it not only damages the wind turbine blades, causing huge economic losses, but also may endanger the personal safety of operators, posing a serious safety hazard to wind power production activities. Therefore, there is an urgent need to develop a new technical solution that can effectively solve the instability problem caused by the upward shift of the center of gravity after the support frame is raised, in order to improve the safety and reliability of the wind turbine blade processing process and ensure the healthy development of the wind power industry. Utility Model Content

[0003] In view of the instability caused by the upward shift of the center of gravity after the support frame is raised in the above-mentioned prior art, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a wind turbine blade support.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wind turbine blade support, comprising,

[0006] The base includes a base plate and two sets of mounting cavities formed inside the base plate;

[0007] The support frame includes a support block disposed at the top of the base plate and a groove formed at the top of the support block, wherein the inner wall of the groove is arc-shaped.

[0008] Mounting brackets are fixedly connected to the top of the base, and the mounting brackets are configured in two sets.

[0009] A drive assembly is disposed at the top of the mounting bracket, the mounting bracket including a drive motor adapted to be mounted at the top of the mounting bracket, a threaded rod fixedly connected to the output end of the drive motor, and a transmission component disposed inside the mounting cavity.

[0010] In a preferred embodiment of the wind turbine blade support of this utility model, a connecting plate is fixedly connected to the outer side of the support block, and a threaded hole is provided at the top of the connecting plate, the threaded hole being threadedly connected to the threaded rod.

[0011] As a preferred embodiment of the wind turbine blade support of this utility model, the outer side of the connecting plate is provided with a guide groove, and the number of the guide grooves is set to at least two sets.

[0012] In a preferred embodiment of the wind turbine blade support of this utility model, a reinforcing plate is fixedly connected to the top of the connecting plate, and the other end of the reinforcing plate is fixedly connected to the side wall of the support block. The reinforcing plate is triangular in shape.

[0013] In a preferred embodiment of the wind turbine blade support of this utility model, the mounting bracket includes an L-shaped support plate fixedly connected to the top of the base plate, and a guide rail fixedly connected to the inner side of the L-shaped support plate. The number of guide rails is the same as the number of guide grooves. The guide grooves are engaged with the guide rails and slide along the outer side of the guide rails.

[0014] In a preferred embodiment of the wind turbine blade support of this utility model, the transmission component includes a rotating rod rotatably connected inside the mounting cavity and a gear fixedly connected to the outside of the rotating rod, wherein one end of the rotating rod near the support block is fixedly connected to the threaded rod.

[0015] As a preferred embodiment of the wind turbine blade support described in this utility model, it further includes:

[0016] An extension assembly, comprising a slide plate slidably connected inside the mounting cavity, a toothed block fixedly connected to the inner side of the slide plate, and a side plate fixedly connected to one end of the slide plate;

[0017] The side plate is disposed on the outside of the base plate, the tooth blocks are configured in multiple sets, and the tooth blocks are meshed with the gears.

[0018] In a preferred embodiment of the wind turbine blade support of this utility model, ball bearings are embedded in the bottom end of the side plate, and the ball bearings are arranged in multiple sets and evenly distributed at the bottom end of the side plate.

[0019] The beneficial effects of this invention are as follows: When the wind turbine blades are placed on the groove at the top of the support block, effective support is achieved, facilitating subsequent processing. When adjusting the equipment height, four drive motors start synchronously, rotating the threaded rod. Because the threaded rod is threadedly connected to the threaded hole and the guide groove is engaged on the outside of the guide rail, the rotation of the threaded rod causes the support block to move along the guide rail, changing the blade height to meet processing requirements. Simultaneously, the rotation of the threaded rod drives the rotating rod and gear at the bottom to rotate. The gear meshes with the gear block, pushing the sliding plate to slide, thereby adjusting the position of the side plate. When the support block is raised, the side plate extends outward, increasing the equipment area to improve stability; when the support block is lowered, the side plate retracts inward, reducing the equipment area. The ball bearings at the bottom of the side plate reduce friction with the bottom surface, ensuring smooth sliding. This design allows for adjustment of the equipment area according to height to ensure stability, and it occupies little space when stored. Attached Figure Description

[0030] Example 1

[0031] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a wind turbine blade support, comprising:

[0032] The base 1 includes a base plate 11 and two sets of mounting cavities 12 formed inside the base plate 11;

[0033] The support frame 2 includes a support block 21 disposed at the top of the base plate 11, and a groove 22 formed at the top of the support block 21, the inner wall of the groove 22 being arc-shaped.

[0034] Mounting bracket 3 is fixedly connected to the top of the base 1, and two sets of mounting bracket 3 are provided.

[0035] The drive assembly 4 is located at the top of the mounting frame 3. The mounting frame 3 includes a drive motor 41 adapted to be mounted at the top of the mounting frame 3, a threaded rod 42 fixedly connected to the output end of the drive motor 41, and a transmission component 43 located inside the mounting cavity 12.

[0036] Preferably, a connecting plate 23 is fixedly connected to the outer side of the support block 21, and a threaded hole 24 is provided at the top of the connecting plate 23, which is threadedly connected to the threaded rod 42.

[0037] Preferably, the outer side of the connecting plate 23 is provided with guide grooves 25, and the number of guide grooves 25 is set to at least two sets.

[0038] Preferably, a reinforcing plate 26 is fixedly connected to the top of the connecting plate 23, and the other end of the reinforcing plate 26 is fixedly connected to the side wall of the support block 21. The reinforcing plate 26 is triangular in shape.

[0039] Furthermore, the mounting bracket 3 includes an L-shaped support plate 31 fixedly connected to the top of the base plate 11, and a guide rail 32 fixedly connected to the inner side of the L-shaped support plate 31. The number of guide rails 32 is the same as the number of guide grooves 25. The guide grooves 25 are engaged with the guide rails 32, and the guide grooves 25 slide along the outer side of the guide rails 32.

[0040] When the wind turbine blades are placed on the grooves 22 at the top of the support block 21, they are effectively supported, facilitating subsequent blade processing. When the height of the equipment needs to be adjusted, four sets of drive motors 41 are simultaneously activated. After starting, the drive motors 41 rotate the threaded rods 42 at their output ends. Since the guide groove 25 is secured to the outside of the guide rail 32, and the threaded rods 42 are threadedly connected to the threaded holes 24, the drive motors 41, through the threaded rods 42, move the support block 21, thereby adjusting its height and ultimately changing the blade height to accommodate different height requirements.

[0041] In summary, when the wind turbine blade is placed on the groove 22 at the top of the support block 21, effective support can be achieved for the blade, facilitating subsequent processing. When the equipment height needs to be adjusted, the four sets of drive motors 41 are started simultaneously, and the threaded rods 42 at their output ends rotate under the drive of the motors. Since the threaded rods 42 are threadedly connected to the threaded holes 24, and the guide grooves 25 are engaged on the outside of the guide rails 32, the rotation of the threaded rods 42 will drive the support block 21 to move along the guide rails, thereby changing the height of the support block 21, and thus adjusting the height of the blades to meet different processing requirements.

[0042] Example 2

[0043] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the transmission component 43 includes a rotating rod 431 rotatably connected inside the mounting cavity 12, and a gear 432 fixedly connected to the outside of the rotating rod 431. The end of the rotating rod 431 near the support block 21 is fixedly connected to the threaded rod 42.

[0044] It also includes an extension component 5, which includes a slide plate 51 slidably connected inside the mounting cavity 12, a toothed block 52 fixedly connected to the inner side of the slide plate 51, and a side plate 53 fixedly connected to one end of the slide plate 51.

[0045] The side plate 53 is located on the outside of the base plate 11, and the toothed blocks 52 are arranged in multiple sets, with the toothed blocks 52 meshing with the gears 432.

[0046] When the threaded rod 42 rotates, it drives the rotating rod 431, which is fixedly connected to the bottom of the threaded rod 42, to rotate. The rotating rod 431 then drives the gear 432 to rotate. Through the meshing of the gear 432 with multiple sets of toothed blocks 52, the sliding plate 51 is moved, ultimately adjusting the position of the side plate 53. When the height of the support block 21 is raised, the side plate 53 is simultaneously extended outward, thereby increasing the overall area of ​​the device and ensuring its stability. Conversely, when the height of the support block 21 is lowered, the side plate 53 is simultaneously retracted inward, thereby reducing the overall area of ​​the device. This device can adjust its overall area according to different heights to ensure stability, while not occupying too much space during storage.

[0047] In summary, when the threaded rod 42 rotates, it drives the rotating rod 431 and gear 432 at its bottom to rotate. The gear 432 meshes with the toothed block 52, pushing the sliding plate 51 to slide, thereby adjusting the position of the side plate 53. When the support block 21 rises, the side plate 53 extends outward, increasing the equipment area to improve stability; when the support block 21 lowers, the side plate 53 retracts inward, reducing the equipment area. This design allows for adjustment of the equipment area according to height to ensure stability, and it occupies little space when stored.

[0048] Example 3

[0049] Reference Figure 4 , Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a ball bearing 54 is embedded in the bottom end of the side plate 53. The ball bearing 54 is arranged in multiple groups and is evenly distributed at the bottom end of the side plate 53.

[0050] The ball bearings 54 installed at the bottom of the side plate 53 can reduce the friction between the side plate 53 and the bottom surface, ensuring the smoothness of the side plate 53 when sliding.

[0051] In summary, when the wind turbine blades are placed on the groove 22 at the top of the support block 21, effective support is achieved, facilitating subsequent processing. When adjusting the equipment height, the four drive motors 41 start synchronously, driving the threaded rod 42 to rotate. Since the threaded rod 42 is threadedly connected to the threaded hole 24 and the guide groove 25 is engaged outside the guide rail 32, the rotation of the threaded rod 42 causes the support block 21 to move along the guide rail, changing the blade height to meet processing requirements. Simultaneously, the rotation of the threaded rod 42 drives the rotating rod 431 and gear 432 at the bottom to rotate. The gear 432 meshes with the toothed block 52, pushing the sliding plate 51 to slide, thereby adjusting the position of the side plate 53. When the support block 21 rises, the side plate 53 extends outward, increasing the equipment area to improve stability; when the support block 21 lowers, the side plate 53 retracts inward, reducing the equipment area. The ball bearings 54 at the bottom of the side plate 53 reduce friction with the bottom surface, ensuring smooth sliding. This design allows for adjustment of the equipment area according to height to ensure stability and occupies little space when stored.
