Description

Technical Field

[0001] This utility model relates to the field of fairing transportation technology, specifically a transportation tool for transporting fairings. Background Technology

[0002] Wind turbine fairings are used to protect the blade roots, hub, and pitch system from wind thrust and harsh external working conditions such as sandstorms, rain, and snow. This reduces stress on the blade roots, extends blade life, and ensures the normal operation of the hub and pitch system.

[0003] Because fairings vary in shape, size, and weight, and some fairings have complex structures and special materials, they are easily damaged during transportation. Therefore, transport fixtures are needed to transport fairings. However, existing fairing transport fixtures are not convenient to adjust according to the curvature of the fairing sidewalls, and their applicability is limited.

[0004] Based on this, a transport fixture for transporting fairings is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a transport fixture for transporting a fairing includes a transport frame 1, a bottom support plate 2, and side support plates 3. The bottom support plate 2 is fixedly connected to the upper surface of the transport frame 1 by a bracket. Two symmetrical side support plates 3 are provided on the upper surface of the transport frame 1 by an adjustment component, which can be adjusted according to the curvature of the fairing side wall.

[0026] In one embodiment, the adjustment assembly includes a worm gear 10, a worm 13, and a turntable 8. Two symmetrical fixed frames 4 are fixedly connected to the upper surface of the transport frame 1. The fixed frames 4 are connected to a rotating shaft 6 via bearings. The rotating shaft 6 is fixedly connected to a side support plate 3. A fixed plate 7 is fixedly connected to the side wall of the fixed frame 4. The worm 13 is connected to the side wall of the fixed plate 7 via bearings. The worm gear 10 is fixedly connected to the rotating shaft 6. The worm gear 10 meshes with the worm 13. The worm 13 is connected to the turntable 8. A rotating handle 9 is provided on the side wall of the turntable 8.

[0027] When transporting the fairing with different curved surfaces, first adjust the angle of the side support plate 3 according to the curved surface. Hold the rotating handle 9 and rotate the turntable 8. The turntable 8 drives the slide rod 18 to rotate. The rotation of the slide rod 18 drives the worm gear 13 to rotate. The rotation of the worm gear 13 drives the worm wheel 10 to rotate. The rotation of the worm wheel 10 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the side support plate 3 to rotate, thereby adjusting the angle of the side support plate 3.

[0028] In one embodiment, a protective cover 5 is fixedly connected to the side wall of the fixed plate 7. The worm gear 10 and the worm 13 are both disposed inside the protective cover 5. A sliding groove is provided on the side wall of the worm 13. A sliding rod 18 is slidably connected to the inner side wall of the sliding groove. The sliding rod 18 is fixedly connected to the turntable 8. A spline block 17 is fixedly connected to one end of the sliding rod 18 located inside the worm 13. A keyway corresponding to the spline block 17 is provided on the inner side wall of the sliding groove. The spline block 17 is slidably connected to the inner side wall of the keyway.

[0029] Pushing the turntable 8 into the protective cover 5 can prevent accidental manual contact with the turntable 8 and the rotating handle 9, which could cause them to rotate and affect the side support plate 3, which has already been adjusted in angle.

[0030] In one embodiment, two snap-fit ​​grooves 14 are provided on the inner sidewall of the keyway, and a limit block groove is provided on the sidewall of the spline block 17. A limit block 12 is slidably connected to the inner sidewall of the limit block groove. The limit block 12 snaps into the snap-fit ​​groove 14, and a spring is fixedly connected between the limit block 12 and the inner wall of the limit block groove.

[0031] The engagement between the locking groove 14 and the limiting block 12 can achieve axial limiting of the turntable 8. On the one hand, it can prevent the turntable 8 from sliding out of the protective cover 5 after the angle is adjusted. On the other hand, it can prevent the turntable 8 from sliding into the protective cover 5 when rotating.

[0032] In one embodiment, a pull block groove is provided on the side wall of the slide rod 18, and a pull block 11 is slidably connected to the inner side wall of the pull block groove. The pull block 11 passes through the turntable 8. A pull rope cavity is provided in the slide rod 18. The limit block groove communicates with the pull block groove through the pull rope cavity. A pull rope 15 is fixedly connected to the side wall of the limit block 12. The other end of the pull rope 15 enters the pull block groove through the pull rope cavity and is fixedly connected to the pull block 11.

[0033] After the adjustment is complete, pull the pull block 11 with one hand. The pull block 11 pulls the limit block 12 into the limit block groove through the pull rope 15, releasing the engagement with the locking groove 14. At this time, push the turntable 8 with the other hand and push the turntable 8 into the protective cover 5. After pushing it into place, release your hand. The limit block 12 enters into another locking groove 14 under the action of the spring and engages with the other locking groove 14.

[0034] In one embodiment, a fixed pulley 16 is rotatably provided on the inner sidewall of the pull rope cavity, and the pull rope 15 passes around the fixed pulley 16. This reduces wear on the pull rope 15.

[0035] The above embodiments disclose a transport fixture for transporting fairings, the specific working principle and process of which are as follows:

[0036] S1: When it is necessary to transport the guide shield according to different curved surfaces, first adjust the angle of the side support plate 3 according to the curved surface. Hold the rotating handle 9 and rotate the turntable 8. The turntable 8 drives the slide rod 18 to rotate. The slide rod 18 drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 10 to rotate. The worm wheel 10 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the side support plate 3 to rotate, thereby realizing the adjustment of the angle of the side support plate 3.

[0037] The worm gear 13 and worm wheel 10 work together to achieve self-locking.

[0038] The adjustment operation is quick and convenient, and it can be flexibly applied to guide fairings with different curved surfaces, thus improving the applicability of the tooling.

[0039] S2: After the adjustment is finished, you can pull the pull block 11 with one hand. The pull block 11 pulls the limit block 12 into the limit block groove through the pull rope 15, and releases the engagement with the locking groove 14. At this time, push the turntable 8 with the other hand and push the turntable 8 into the protective cover 5. After pushing it into place, release your hand. The limit block 12 enters into another locking groove 14 under the action of the spring and engages with the other locking groove 14.

[0040] Pushing the turntable 8 into the protective cover 5 can prevent accidental manual contact with the turntable 8 and the rotating handle 9, which could cause them to rotate and affect the side support plate 3 that has been adjusted to the correct angle.

[0041] The engagement between the locking groove 14 and the limiting block 12 can achieve axial limiting of the turntable 8. On the one hand, it can prevent the turntable 8 from sliding out of the protective cover 5 after the angle is adjusted. On the other hand, it can prevent the turntable 8 from sliding into the protective cover 5 when rotating.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
