[0029] A wind turbine blade transport support tooling includes a base 1, a carrier plate 3 and a support frame 5, wherein a rubber seat 14 is fixed to the upper surface of the base 1, the carrier plate 3 is arranged above the base 1, and the lower surface of the carrier plate 3 contacts the top of the rubber seat 14, and a plurality of spring seats 2 are arranged between the carrier plate 3 and the base 1, the spring seats 2 are arranged at the four corners of the carrier plate 3, and the top and bottom of the spring seats 2 are fixedly connected to the carrier plate 3 and the base 1 respectively.

[0030] The support frame 5 is arranged above the carrier plate 3, and a plurality of hydraulic telescopic rods 4 are arranged between the support frame 5 and the carrier plate 3. The hydraulic telescopic rods 4 are arranged at the four corners of the support frame 5, and the top and bottom of the hydraulic telescopic rods 4 are fixedly connected to the support frame 5 and the carrier plate 3 respectively.

[0031] A support frame 13 is welded to the upper surface of the carrier plate 3, and a threaded hole is opened on the upper surface of the support frame 13. A threaded column 9 is screwed into the threaded hole of the support frame 13, and an axle seat 10 is fixed to the top of the threaded column 9. The top of the threaded column 9 is movably connected to the support frame 5 through the axle seat 10.

[0032] A rubber plate 7 is bonded to the interior of the support frame 5 , and the upper surface of the rubber plate 7 is an arc-shaped structure. The arc-shaped structure can ensure a perfect fit with the blades and ensure a larger contact surface between the rubber plate 7 and the blades.

[0033] The rubber sheet 7 can also be designed as a multi-layer rubber sheet, where multiple layers of rubber sheets 7 are added inside the support frame 5, and a flexible fitting surface is formed by combining rubber materials of different hardness to provide a better buffering effect. The multiple layers of rubber sheets are bonded together with glue.

[0034] The outer sleeve of the threaded column 9 is provided with a nut 12, which is located at the inner side of the support frame 13. The bottom end of the threaded column 9 is fixedly connected with an adjustment seat 11, and a power-assisting hole 15 is provided on the outer surface of the adjustment seat 11. When the threaded column 9 needs to be rotated to adjust the height of the support frame 5, a steel pipe or a cylindrical rod is inserted into the power-assisting hole 15 to drive the adjustment seat 11 to rotate the threaded column 9.

[0035] In this embodiment, the rubber seat 14 and the spring seat 2 are arranged between the base 1 and the carrier plate 3 to play a buffering and protective role in the process of supporting the blades of the wind turbine;

[0036] When the blades of the wind turbine are placed on the surface of the rubber plate 7 and the height of the support frame 5 needs to be finely adjusted, the threaded column 9 is screwed through the adjustment seat 11, and the threaded column 9 rotates relative to the support frame 13. At the same time, the threaded column 9 pushes up the support frame 5 through the shaft seat 10, and the adjustment process is convenient. After the height adjustment of the support frame 5 is completed, the nut 12 is screwed relative to the threaded column 9 until the nut 12 fits the inner bottom end of the support frame 13 to maintain the stability of the threaded column 9 relative to the support frame 13.

[0037] Example 2

[0038] The structure of this embodiment is basically the same as that of embodiment 1, except that, in this embodiment, an isolation assembly and a buffer block are installed on the outside of the support frame 5, the isolation assembly includes an isolation plate 8 and a damping rod 16, the damping rod 16 is symmetrically installed on the surface of the isolation plate 8, and a weight-reducing hole 17 is opened on the surface of the isolation plate 8.

[0039] A receiving groove 18 is provided on the side wall of the support frame 5, and two guide grooves 19 are symmetrically provided on the bottom side wall of the receiving groove 18. The damping rod 16 is inserted into the guide groove 19 so that the damping rod 16 can slide relative to the support frame 5 in the guide groove 19. Thus, relative movement between the isolation plate 8 and the support frame 5 is achieved, and when the isolation plate 8 is close to the support frame 5, the isolation plate 8 can be stored in the receiving groove 18.

[0040] During transportation, by pulling out the damping rod 16, a certain distance is formed between the isolation plate 8 and the support frame 5. Some buffer blocks or buffer materials are placed in this distance to play a buffering role and prevent the shaking during transportation from causing damage to the blades on the support frame 5.

[0041] In the above embodiment, in order to facilitate the movement of the device, lifting ears 6 are respectively provided on both sides of the base 1. The device can be transferred to the transport vehicle through the lifting ears by a lifting device, and the base 1 can be stably placed in a suitable position on the vehicle. And the position of the base can be adjusted by pulling with a steel chisel with a hook. When the blade is transferred to the transport vehicle, the suspended position of the blade is supported by the device. By hooking the hook of the steel chisel into the empty slot of the lifting ear 6, the base is pulled and moved, thereby ensuring a good supporting effect of the device on the blade.

[0045] The blades of the wind turbine are placed on the surface of the rubber plate 7. When the height of the support frame 5 needs to be fine-tuned, the threaded column 9 is screwed through the adjustment seat 11, and the threaded column 9 rotates relative to the support frame 13. At the same time, the threaded column 9 pushes up the support frame 5 through the shaft seat 10, and the adjustment process is convenient; after the height adjustment of the support frame 5 is completed, the nut 12 is screwed relative to the threaded column 9 until the nut 12 fits the inner bottom end of the support frame 13 to maintain the stability of the threaded column 9 relative to the support frame 13;

[0046] An isolation component is installed on the outside of the support frame 5. The damping rod 16 of the isolation plate 8 is slidably inserted into the inside of the guide groove 19, and the isolation plate 8 is pulled relative to the support frame 5. The isolation plate 8 and the damping rod 16 form an isolation protection structure. Some elastic materials such as elastic sponge blocks or rubber blocks are placed between the isolation plate 8 and the support frame 5, which has a good isolation effect.

[0047] The utility model provides a rubber seat and a spring seat between the base and the carrier plate, which can provide buffer protection for the blades of the wind turbine during the supporting process; the support frame arranged on the carrier plate can adjust the height of the support frame through the threaded column, thereby ensuring that the rubber plate 7 on the support frame fits perfectly with the bottom of the blade to be supported, ensuring the supporting effect and good supporting stability.

[0048] In the above embodiment, a cushion pad made of polymer material can also be provided on the base and the carrier plate, and the cushion pad is placed in the space between the rubber seat 14 and the spring seat 2. The cushion pad made of polymer material has better shock absorption and protection effect. The cushion pad made of polymer material can be made of polyurethane, polyethylene, silicone or rubber material.

[0049] A threaded column is screwed into the threaded hole position of the support frame of the carrier plate, and the top of the threaded column is movably connected to the support frame through the shaft seat. The wind turbine blades are placed on the surface of the rubber plate. When the height of the support frame needs to be fine-tuned, the threaded column is screwed through the positioning seat, and the threaded column rotates relative to the support frame. At the same time, the threaded column pushes up the support frame through the shaft seat. The adjustment process is convenient.
