Description

Technical Field

[0001] This utility model belongs to the field of wind turbine spraying and clamping technology, specifically referring to a wind turbine blade spraying and clamping fixture. Background Technology

[0002] To protect the outer structure of the wind turbine and blades, a protective paint needs to be sprayed onto their surfaces to increase their service life. However, the wind turbine is not properly secured when the protective paint is applied, and it is prone to shaking and rotating during the spraying process, which affects the spraying efficiency. Therefore, a wind turbine and blade spraying clamping fixture is proposed to solve the above-mentioned problems.

[0003] Existing technologies, such as the publication (announcement) number CN23377361U, disclose a wind turbine blade spraying clamping fixture. This utility model uses the threaded connection of a fixed support rod and a fixed nut to limit the wind turbine, preventing it from shaking and shifting. Then, according to the diameter of the wind turbine, the handle is pulled to fix the wind turbine under the action of the return spring, increasing the stability of the wind turbine when subjected to spraying impact.

[0004] However, there are still problems such as cumbersome disassembly and assembly procedures during use, the need for technicians to move the sprayer during the spraying process, and the risk of scratching the fan blades when clamping them, which affects their service life. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model simplifies the disassembly and assembly process during use, facilitates the spraying of the fan blades by technicians, and reduces the scraping of the fan blades during clamping, thus extending their service life.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows:

[0007] A wind turbine blade spraying clamping fixture includes a base with a circular groove on the top and a rotating boss protruding upward inside the circular groove. It also includes a rotating device, a support platform, a wind turbine fixing mechanism, and a blade clamping mechanism.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1As shown, a wind turbine blade spraying clamping fixture includes a base 1, the top of which has a circular groove, and a rotating boss 2 protruding upward inside the circular groove. It also includes a rotating device 3, a support platform 4, a wind turbine fixing mechanism 5, and a blade clamping mechanism 6. The bottom of the rotating device 3 is fixedly connected to the top of the rotating boss 2, and its top is fixedly connected to the bottom of the support platform 4. The middle of the support platform 4 is fixedly connected to the bottom of the wind turbine fixing mechanism 5, and its edge is fixedly connected to several blade clamping mechanisms 6.

[0025] When operating this device, the wind turbine shaft is fixed by the wind turbine fixing mechanism 5, and the fan blade clamping mechanism 6 clamps the fan blades to achieve the clamping function and prevent vibration during spraying. When it is necessary to spray the wind turbine fan blades at other angles, the rotating support platform 4 rotates on the rotating device 3 to the required angle for spraying.

[0026] The rotating device 3 includes a turntable 7, a rotating block 8, a large rotating wheel 9, a rotating rod 10, two short rotating rods 11, and two small rotating wheels 12. The bottom of the turntable 7 is fixedly connected to the inside of a circular groove, and its top is rotatably connected to the bottom of the rotating block 8. The top of the rotating block 8 is rotatably connected to the bottom of the wind turbine fixing mechanism 5. The bottom of the large rotating wheel 9 is rotatably connected to the upper end of the rotating boss 2, and its side is pressed against the side wall of the circular groove. Its top is fixedly connected to the bottom of the rotating rod 10. The top of the rotating rod 10 is fixedly connected to the bottom of the support platform 4. The bottoms of the two small rotating wheels 12 are rotatably connected to the upper end of the rotating boss 2, and their tops are fixedly connected to the bottom of the short rotating rods 11. The tops of the short rotating rods 11 are fixedly connected to the bottoms of the two ends of the support platform 4.

[0027] When the device is rotated, the large rotating wheel 9 and the small rotating wheel 12 rotate and shift on the rotating boss 2, so that during the rotating spraying, the uneven spraying caused by the shaking of the fan blades during rotation is prevented.

[0028] like Figure 2 As shown, the support platform 4 is a horizontally placed A-shaped structure, with an L-shaped rod 13 fixedly connected to its tip and fixed columns 14 fixedly connected to both ends of its end. A rotating shaft 15 is connected to the top of the fixed column 14, and the other end of the rotating shaft 15 and the top of the L-shaped rod 13 are both connected to the fan blade clamping mechanism 6.

[0029] Since the blade clamping mechanism 6 is set at a certain height by the L-shaped rod 13, and the other two blade clamping mechanisms 6 are set in different positions by the fixing column 14, the function of clamping wind turbine blades over a wider range can be realized.

[0030] The wind turbine fixing mechanism 5 includes a support platform 16, a telescopic rod 17, a spherical bearing 18, and a shaft-connected hollow tube 19. The bottom of the support platform 16 is fixedly connected to the top of the rotating block 8, and the top of the support platform 16 is fixedly connected to the non-moving end of the telescopic rod 17. The movable end of the telescopic rod 17 is connected to the bottom of the spherical bearing 18, and the shaft-connected hollow tube 19 is connected to one side of the spherical bearing 18.

[0031] The wind turbine blades are fitted with a shaft sleeve in the hollow tube 19. The telescopic rod 17 works in conjunction with the ball bearing 18 to spray wind turbines of different specifications, and it is more flexible during spraying.

[0032] like Figure 3-4 As shown, the fan blade clamping mechanism 6 includes a grooved plate 20, two U-shaped clamping plates 21, a sliding block 22, a locking groove 23, a rotating ball 24, a telescopic rod 25, and a locking block 26. The grooved plate 20 is a strip-shaped plate structure with a groove on one side. The sliding blocks 22 are fixedly connected to one side of each of the two U-shaped clamping plates 21. The sliding blocks 22 slide within the grooves of the grooved plate 20. The locking groove 23 is fixedly connected to the front side of one U-shaped clamping plate 21, and the rotating ball 24 is fixedly connected to the front side of the other U-shaped clamping plate 21. The non-moving end of the telescopic rod 25 is fixedly connected to the top of the rotating ball 24, and the locking block 26 is fixedly connected to the movable end of the telescopic rod 25. The two U-shaped clamping plates 21 slide closer or further apart through the sliding block 22. The locking block 26 engages with the locking groove 23 during rotation.

[0033] Two U-shaped clamping plates 21 slide close to each other in the sliding groove of the groove plate 20 via sliding block 22, clamping the fan blade, and then rotating the rotating ball 24 to stretch the telescopic rod 25 to the snap-fit ​​length, thereby snapping the snap-fit ​​block 26 into the snap-fit ​​groove 23.

[0034] A pad is laid on the inner periphery of the U-shaped clamping plate 21.

[0035] By laying a pad on the inner periphery of the U-shaped clamping plate 21, the risk of fan blade scratching is reduced.
