Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation tooling technology, and in particular to a fixed support for transporting wind turbine blades. Background Technology

[0002] A wind turbine generator set mainly consists of three parts: the tower, the nacelle, and the rotor. The rotor is mainly responsible for converting wind energy into mechanical energy. The rotor mainly includes wind turbine blades and a hub. The wind turbine blades are connected to the hub through their blade roots. The wind turbine blades are one of the core components of a wind turbine generator set. If the materials of the wind turbine blades gradually age or are damaged by extreme weather, the damaged wind turbine blades need to be replaced in a timely manner.

[0003] Due to the large size, weight, and length of wind turbine blades, their transportation is extremely troublesome. It is necessary to ensure that the wind turbine blades are placed stably to prevent damage during transportation. In the current technology, special transport vehicles are usually used to transport wind turbine blades. These vehicles are usually equipped with special brackets to support the blade roots, and the blades are fixed by bolts to the blade roots.

[0004] The problem with the above technology is that since wind turbine blades come in various sizes, the support can only fix the blade root of one type of wind turbine blade, which can only meet the transportation needs of one type of wind turbine blade. If other types of wind turbine blades need to be transported, the entire support is usually replaced to match the different types of wind turbine blades, resulting in poor versatility.

[0014] In one embodiment, the fixing mechanism further includes a crossbeam that extends laterally and whose two ends are respectively fixedly connected to the two fixing plates.

[0015] In one embodiment, the base includes a bottom plate, a top plate, and a plurality of reinforcing plates. Each reinforcing plate is arranged vertically, and the top and bottom of each reinforcing plate are respectively connected to the top plate and the bottom plate. The plurality of reinforcing plates are arranged at intervals in the horizontal direction.

[0024] This utility model proposes a fixed support 100 for transporting wind turbine blades.

[0025] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the fixed support 100 for transporting wind turbine blades includes a base 1, a support mechanism 2, and a fixing mechanism 3. The base 1 extends laterally. The support mechanism 2 includes a buffer support 23 and two brackets 21. The two brackets 21 are spaced apart laterally, and each bracket 21 can be slidably disposed on the top of the base 1 so that the two brackets 21 can move closer or further apart from each other. The buffer support 23 is disposed on the top of the base 1 and located between the two brackets. The buffer support 23 and the two brackets 21 are used to support the blade roots of the wind turbine blades. The fixing mechanism 3 includes two fixing plates 31. The two fixing plates 31 are disposed on the top of the base 1, and the two fixing plates are respectively located on one side of the two brackets along the longitudinal direction. Each fixing plate 31 has a plurality of vertically extending strip-shaped through holes 311, and the plurality of strip-shaped through holes 311 are spaced apart laterally. The end face of the blade root supported on the top surface of the plurality of brackets 21 is connected to the plurality of strip-shaped through holes 311.

[0026] The present invention discloses a fixed support 100 for transporting wind turbine blades. By employing two brackets 21 to support different positions of the blade root, the stability of the blade root during transportation is effectively ensured. Each bracket 21 is slidably connected to the top of the base 1. By adjusting the position of each bracket 21 on the base 1, the two brackets 21 can be moved closer or further apart, thereby supporting the blade roots of wind turbine blades of different sizes. Two fixing plates 31 are provided on both sides of the support mechanism 2, each with a strip-shaped through hole 311. Depending on the size of the blade root, the blade root can be fixed with bolts through different holes in the strip-shaped through holes 311. In other words, by adjusting the position of the two brackets 21, the fixed support 100 can support the blade roots of various sizes of wind turbine blades, improving its versatility. Furthermore, by providing a buffer bracket 23 located between the two brackets 21, it provides central support, effectively distributing the weight of the wind turbine blade, maintaining blade shape stability, and preventing structural damage. The buffer bracket 23 is also used to buffer the leaf root when it is placed on the two brackets 21, so as to avoid the leaf root from being damaged by direct collision with the two brackets 21, thus improving reliability.

[0027] In addition, the blade root is supported from below by the bracket 21, and is connected to the blade root end face by bolts through the strip-shaped through hole 311 on the fixing plate 31. This achieves a dual fixing method of bottom support and end face fixing, which can effectively distribute the weight of the blade and prevent shaking, slippage or damage caused by bumps during transportation, thus ensuring the stability and safety of the wind turbine blade during transportation.

[0028] It should be noted that, as Figure 1As shown, the horizontal, vertical, and longitudinal directions are left-right, front-back, and up-down directions, respectively. The two brackets 21 can move left and right.

[0029] In one embodiment, the top of the base 1 is provided with a sliding hole 111 extending laterally, and the bottom of each bracket 21 is provided with a connecting plate 22. The connecting plate 22 is supported on the top of the base 1, and a fastener 221 is provided on the connecting plate 22. The fastener 221 extends into the sliding hole 111 and slides laterally with the sliding hole 111. The fastener 221 can lock the connecting plate 22 onto the base 1 or unlock it from the base 1.

[0030] Understandably, the sliding hole 111 extends laterally, providing a continuous adjustment path for the fastener 221. By loosening the fastener 221, the connecting plate 22 and the bracket 21 can be slid along the sliding hole 111 to the desired position. After adjustment, tightening the fastener 221 again will securely lock the bracket 21 onto the base 1, allowing the distance between the two brackets 21 to be precisely adjusted according to the blade root position of different wind turbine blade models, making it highly adaptable.

[0031] Furthermore, the fastener 221 can be a fastening bolt in the prior art, with the nut of the fastening bolt located below the sliding hole 111, the screw thread passing through the connecting plate 22, and the nut located above the connecting plate 22.

[0032] In one embodiment, the buffer bracket 23 includes a support plate 231 and a buffer assembly 232. The support plate 231 is located above the base 1 and is used to support the blade root of the wind turbine blade. The buffer assembly 232 includes a guide rod 2321 and an elastic member 2322. The guide rod 2321 extends vertically, and the support plate 231 is connected to the top of the guide rod 2321. A guide hole is provided on the base 1. The guide rod 2321 can slide vertically through the guide hole, and the elastic member 2322 is sleeved on the guide rod 2321. Both ends of the elastic member 2322 abut against the support plate 231 and the base 1, respectively.

[0033] Understandably, when the blade root of the wind turbine blade is installed and fixed, the blade root is first supported on the support plate 231, and the elastic element 2322 is compressed under the weight of the blade root. Then the blade root is supported on the two brackets 21. The elastic element 2322 buffers the blade root, effectively reducing the interaction force when the blade root collides with the bracket 21, thus avoiding damage to the blade. Furthermore, by setting a guide rod 2321, which is slidably inserted into the base 1, the elastic element 2322 is sleeved outside the guide, which can effectively prevent the elastic element 2322 from being twisted and damaged.

[0034] Furthermore, there are multiple buffer components 232, which are arranged in an array. By setting multiple buffer components 232, the buffering effect is better.

[0035] Furthermore, a limit block is provided at the bottom of the guide rod 2321. The limit block is located below the through hole, and the size of the limit block is larger than the size of the guide hole. By setting the limit block, the guide rod 2321 can be effectively prevented from falling off.

[0036] In one embodiment, each bracket 21 includes a support plate 211 and a support frame 212. The support frame 212 is connected to the top of the connecting plate 22, and the support plate 211 is connected to the top of the support frame 212. The support frame 212, the connecting plate 22, and the support plate 211 together form a cavity. The support frame 212 is provided with a weight reduction hole 2121 communicating with the cavity.

[0037] Understandably, the bracket 21 includes a tray 211 and a support frame 212, and the support frame 212, the connecting plate 22 and the tray 211 together form a cavity, which not only reduces the amount of material used, but more importantly, reduces the overall weight of the fixed bracket 100, making it easier to transport. Furthermore, by providing weight-reducing holes 2121 on the support frame 212, the weight is further reduced.

[0038] Specifically, the pallet 211 and the support frame 212 are fixedly connected by welding, and the support frame 212 and the connecting plate 22 are also fixedly connected by welding, which not only makes the connection stable but also provides good stability.

[0039] In one embodiment, each pallet 211 is inclined upwards from one end near the buffer bracket 23 to the other. By inclining the pallets 211, the blade roots can be supported and their lateral movement limited, resulting in better transport stability.

[0040] In one embodiment, each support plate 211 is provided with a cushioning pad 2111 on its top, and the cushioning pad 2111 completely covers the top of the corresponding support plate 211. Understandably, by providing the cushioning pad 2111, direct rigid contact between the support plate 211 and the blade root is avoided, thereby effectively preventing damage such as blade root scratches and effectively protecting the overall wind turbine blade.

[0041] Specifically, the cushioning pad 2111 can be made of rubber, polyurethane or other polymer elastic materials.

[0042] In one embodiment, each bracket 21 is provided with an adjustment component 24 on the side away from the buffer bracket 23. Each adjustment component 24 includes a limiting plate 241 and an adjustment screw 242. The limiting plate 241 extends longitudinally, and the adjustment screw 242 extends laterally. The limiting plate 241 has a screw hole, and the adjustment screw 242 passes through the screw hole. The end of the adjustment screw 242 near the corresponding bracket 21 is rotatably connected to the bracket 21.

[0043] By setting an adjustment component 24, which includes a limiting plate 241 and an adjustment screw 242, the adjustment screw 242 can be moved left and right relative to the limiting plate 241, thereby driving the corresponding bracket 21 to move left and right, and thus allowing for fine adjustments to the bracket 21. Understandably, the adjustment screw 242 can also provide lateral support for the bracket 21. When the blade root is supported on the bracket 21, the bracket 21 is subjected to lateral forces; that is, the left bracket 21 is subjected to a leftward force from the blade root, and the left adjustment screw 242 can support the left bracket 21, offsetting part of the leftward force; the right bracket 21 is subjected to a rightward force from the blade root, and the right adjustment screw 242 can support the right bracket 21, offsetting part of the rightward force, further enhancing the stability of the bracket 21.

[0044] Specifically, the adjusting screw 242 can be a lead screw in the prior art. The adjusting screw 242 is threadedly connected to the limiting plate 241. By rotating the adjusting screw 242, the adjusting screw 242 can move left and right relative to the limiting plate 241. The adjusting screw 242 is rotatably connected to the bracket 21, so that the relative position between the adjusting screw 242 and the bracket 21 remains unchanged when the adjusting screw 242 rotates.

[0045] In one embodiment, a reinforcing rib 32 is provided on one side of each fixing plate 31 along the longitudinal direction on the base 1, and each reinforcing rib 32 is fixedly connected to the corresponding fixing plate 31. It can be understood that by providing the reinforcing rib 32 and fixing it to the fixing plate 31, the stability of the fixing plate 31 is further improved, and the fixing plate 31 is prevented from bending and being damaged relative to the base 1, resulting in better reliability.

[0046] In one embodiment, the fixing mechanism 3 further includes a crossbeam 33, which extends laterally and is fixedly connected to two fixing plates 31 at its two ends along the lateral direction. By setting the crossbeam 33, the crossbeam 33 connects the two independent fixing plates 31 into a whole in the lateral direction, forming a frame structure, which significantly improves the bending, torsional and lateral deformation resistance of the two fixing plates 31. It can effectively prevent the fixing plates 31 from tilting, loosening or becoming unstable due to vibration, bumps or lateral forces during transportation, and ensure a firm constraint on the root of the wind turbine blade.

[0047] In one embodiment, the base 1 includes a base plate 12, a top plate 11, and a plurality of reinforcing plates 13. Each reinforcing plate 13 is arranged vertically, and its top and bottom are respectively connected to the top plate 11 and the base plate 12. The plurality of reinforcing plates 13 are arranged at intervals along the horizontal direction. A buffer bracket 23, two brackets 21, and two fixing plates 31 are all disposed on the top of the top plate. Understandably, the base 1 is composed of a base plate 12, a top plate 11, and reinforcing plates 13, which facilitates individual manufacturing and assembly. The base plate 12 is parallel to the bottom surface, and the bottom surface of the base plate 12 is flat, making it more stable when placed. Supported by the plurality of reinforcing plates 13, the structure is stable, and it also saves materials, reduces the weight of the entire base 1, and is easy to transport.

[0048] Specifically, the top and bottom of the reinforcing plate 13 are fixedly connected to the top plate 11 and the bottom plate 12 by welding, respectively.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made under the technical concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
