[0025] Embodiment 1: A wind turbine blade lifting tool, such as Figure 1-Figure 4As shown, it includes a support rod 2 and an auxiliary rope 3 slidably arranged at the upper end of the support rod 2. There are at least two auxiliary ropes 3, and the two auxiliary ropes 3 are relatively distributed. The auxiliary rope 3 extends to the lower end of the support rod 2. The lower end of the auxiliary rope 3 is fixedly connected to at least two connectors 4, and the lower end of the connector 4 is fixedly connected to at least two auxiliary belts 5. The end of the auxiliary belt 5 away from the connector 4 is plugged with a pulling support ring 6, and the two pulling support rings 6 are simultaneously fixedly connected with a sliding connection block 7. The adjacent sides of the two sliding connection blocks 7 are respectively provided with a plug-in auxiliary plate 16 and a sliding plug-in plate 10. The sliding plug-in plate 10 is plugged with a plug-in auxiliary groove 17. The plug-in auxiliary plate 16 is plugged with a plug-in support groove 11. The plug-in support groove 11 is located below the plug-in support groove 11, and the plug-in auxiliary groove 17 is located above the plug-in auxiliary plate 16. The plug-in auxiliary groove 17 and the plug-in support groove 11 are respectively opened on the adjacent sides of the two sliding connection blocks 7. When the device is running, the auxiliary rope 3 is pulled under the sliding support of the support rod 2. The two auxiliary belts 5 at the bottom are pulled and contracted under the support of the connector 4, so that the two sliding connection blocks 7 at the lower end are contracted under the support of the auxiliary belts 5 on both sides. The contraction of the two sliding connection blocks 7 will drive the sliding plug-in plate 10 and the plug-in auxiliary plate 16 to move in the opposite direction at the same time, so that the sliding plug-in plate 10 is moved and plugged into the inside of the plug-in auxiliary groove 17, and the plug-in auxiliary plate 16 is moved and plugged into the inside of the plug-in support groove 11. By plugging and limiting the two sliding connection blocks 7, the device can fasten and support the blade material in the middle, and through the gravity support of the blade by the device, the effect of continuously moving the limiting component downward is achieved, so that the two sliding connection blocks 7 are tightened, ensuring that the device is stable when lifting, and by limiting the length of the plug-in component itself, the fastening component only has the effect of limiting and clamping the fixed part of the blade, thereby effectively preventing the sliding of the blade when lifting, and improving the safety and stability of the device for lifting the blade.

[0026] like Figure 1-Figure 4 As shown, the sliding plug plate 10 is slidably connected to the sliding connecting block 7, and the sliding plug plate 10 extends to the inside of the sliding connecting block 7. The plug-in auxiliary plate 16 and the sliding plug plate 10 are connected in the same manner. The two sliding connecting blocks 7 respectively support the sliding inner side of the plug-in auxiliary plate 16 and the sliding plug plate 10 to ensure the directional stability of the fastening components on both sides when they are plugged in and fastened.

[0027] like Figure 1-Figure 4As shown, a telescopic spring 8 is fixedly connected to one side of the inner wall of the sliding connection block 7, and the telescopic spring 8 is fixedly connected to the sliding plug plate 10. An arc-shaped sliding rod 9 is arranged in the middle of the telescopic spring 8, and the arc-shaped sliding rod 9 is fixedly connected to the sliding plug plate 10. The sliding plug plate 10 is slidably connected to the sliding connection block 7. The sliding of the sliding plug plate 10 inside the sliding connection block 7 will drive the telescopic spring 8 and the arc-shaped sliding rod 9 on one side to stretch, and then through the elastic retraction of multiple telescopic springs 8, when the blades are relaxed after installation, the telescopic spring 8 will retract and reset, so that the sliding plug plate 10 and the arc-shaped sliding rod 9 will reset and slide in the sliding connection block 7, thereby automatically releasing the restriction on the blades, which can facilitate the removal of the fastening components.

[0028] Embodiment 2: A wind turbine blade lifting tool, such as Figure 1-Figure 4 As shown, the sliding connection block 7 is slidably connected to a rotating support block 12 at one end away from the sliding plug-in plate 10, and the sliding connection block 7 extends into the interior of the rotating support block 12. A fastening auxiliary ring 15 is arranged between the two rotating support blocks 12, and rotating columns 13 are rotatably arranged inside the opposite ends of the fastening auxiliary ring 15. The rotating column 13 is plugged with a rotating rod 14, and the rotating rod 14 extends out of the two ends of the rotating column 13. The rotating rod 14 is rotatably arranged on the fastening auxiliary ring 15, and the rotating support block 12 is fixedly arranged on the outside of the rotating column 13. By supporting the sliding and limiting position of the sliding connection block 7 by the rotating support block 12, the convenience of adjusting the length of the sliding connection block 7 is improved, and by supporting the rotating position of the rotating rod 14 and the rotating column 13, it is ensured that when the fastening auxiliary ring 15 and the two rotating support blocks 12 are used in combination, it is convenient to adjust the outer limit range thereof, thereby improving the convenience of fastening and resetting the device.

[0029] like Figure 1-Figure 4 As shown, the support rod 2 is inserted with the support belt 1 and extends to its outside, and the support belt 1 is located between two tightening auxiliary rings 15. The normal operation of the blade when lifting is ensured by the support of the support belt 1, and the support belt 1 and the tightening auxiliary rings 15 on both sides can be operated in and out respectively under the limiting guidance of the support rod 2.

[0030] Working principle: by pulling the auxiliary rope 3 under the sliding support of the support rod 2, the two auxiliary belts 5 below are pulled and contracted under the support of the connector 4, so that the two sliding connection blocks 7 at the lower end are contracted under the support of the auxiliary belts 5 on both sides, and the contraction of the two sliding connection blocks 7 will drive the sliding plug-in plate 10 and the plug-in auxiliary plate 16 to move in the opposite direction at the same time, so that the sliding plug-in plate 10 is moved and plugged into the inside of the plug-in auxiliary groove 17, and the plug-in auxiliary plate 16 is moved and plugged into the inside of the plug-in support groove 11. By inserting and limiting the two sliding connection blocks 7, the device can fasten and support the blade material in the middle, and under the gravity support of the blade by the device, the limiting component can be continuously moved downward, so that the two sliding connection blocks 7 are more fastened, ensuring that the device is stable when lifting, and by limiting the length of the plug-in component itself, the fastening component only has the effect of limiting and clamping the fixed part of the blade, thereby effectively preventing the sliding of the blade when lifting, and improving the safety and stability of the device for lifting the blade.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
