Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0024] Referring to Figures 1-4 , the present invention provides an automatic high-altitude hook device for a sling used in wind power, including:

[0025] A beam body 15, on which a lifting mechanism is provided, and a towing rope 2 is provided at the output end of the lifting mechanism;

[0026] Two hook mechanisms 4, the hook mechanism 4 includes a connecting frame 14, the two connecting frames 14 are respectively connected to both ends of the beam body 15, a through groove is provided vertically on the connecting frame 14, a driving component is provided on the connecting frame 14, and the output end of the driving component is fixedly connected with a telescopic shaft 8 parallel to the ground. The telescopic shaft 8 penetrates the side wall of the connecting frame 14 and extends into the through groove; a guiding component is provided on the connecting frame 14, and the towing rope 2 extends into the through groove through any one of the guiding components; the towing rope 2 located in the through groove is perpendicular to the ground under the action of gravity;

[0027] A suspension sling 13, both ends of the suspension sling 13 are fixedly connected with rigid connection rings 11 respectively, the bottom of the towing rope 2 extends out of the through groove and is fixedly connected with any one of the rigid connection rings 11, and the two telescopic shafts 8 are respectively slidably connected with the inner walls of the two rigid connection rings 11;

[0028] A first displacement sensor (not shown in the figure) is fixedly connected to the connecting frame 14, which is used to detect the extension length of the telescopic shaft 8, so as to facilitate the regulation of the connection state and connection length between the telescopic shaft 8 and the rigid connection ring 11. At the same time, a second position sensor is also arranged on the connecting frame 14, which is used to detect the position of the rigid connection ring 11. When the rigid connection ring 11 reaches the specified position aligned with the telescopic shaft 8, it will transmit information to the controller, which is convenient for the connection between the rigid connection ring 11 and the telescopic shaft 8.

[0029] During use, on the ground, the rigid connection ring 11 away from the traction rope 2 is placed into the through groove of the connecting frame 14, and the telescopic shaft 8 is extended into the rigid connection ring 11 through the driving assembly to complete the hooking work on one end of the sling 13. The beam body 15 is lifted to a high altitude, and the two connecting frames 14 are respectively located at both ends of the blade. At this time, the sling 13 is located below the blade. The traction rope 2 is lifted upward through the lifting mechanism, so as to drive the rigid connection ring 11 to rise and gradually lift the rigid connection ring 11 into the through groove. When the rigid connection ring 11 is aligned with the telescopic shaft 8, it stops. The driving assembly drives the telescopic shaft 8 to extend into the rigid connection ring 11, so as to automatically complete the hooking work on the other end of the sling 13.

[0030] In a further optimized solution, the guiding assembly includes a guiding pulley group 6 rotatably connected to the outer side wall of the connecting frame 14. A guide rope groove 10 is formed on the side wall of the connecting frame 14. A guide wheel 9 is rotatably connected to the inner wall of the through groove. The axis of the guide wheel 9 is parallel to the axis of the guiding pulley group 6, and the center line of the guide rope groove 10 is perpendicular to the axis of the guiding pulley group 6.

[0031] The traction rope 2 is located outside the connecting frame 14. The traction rope 2 is redirected by the guiding pulley group 6, passes through the guide rope groove 10 and then enters the through groove of the connecting frame 14. Then, the traction rope 2 is located at the middle position of the through groove through the guide wheel 9. When the rigid connection ring 11 is lifted into the through groove, it is convenient to make the rigid connection ring 11 located at the middle of the through groove, so as to facilitate alignment with the telescopic shaft 8.

[0032] In a further optimized solution, the driving assembly includes a cylinder 5 fixedly connected to the outer side wall of the connecting frame 14. The output end of the cylinder 5 is fixedly connected to the telescopic shaft 8.

[0033] In a further optimized solution, the lifting mechanism includes a winch 1 fixedly connected to the beam body 15. A traction rope 2 is wound around the reel of the winch 1. A redirecting pulley group 3 is rotatably connected to the beam body 15. The traction rope 2 is redirected from being parallel to the ground to being perpendicular to the ground through the redirecting pulley group 3.

[0034] The winch 1 serves as a power source, transmits the traction force through the traction rope 2, and the redirecting pulley group 3 changes the direction of the traction rope 2 to make the traction rope 2 perpendicular to the ground, which is convenient for lifting the rigid connection ring 11.

[0035] For a further optimized solution, guide plates 7 are fixedly connected to both sides of one end of the connecting frame 14 away from the beam body 15. The two guide plates 7 are arranged in a V-shaped pattern, and the through slot is located in the middle between the two guide plates 7.

[0036] The two guide plates 7 facilitate the preliminary guiding of the rigid connection ring 11, making it easier for the rigid connection ring 11 to smoothly enter the through slot.

[0037] For a further optimized solution, an adjusting cable 12 is also fixedly connected to the rigid connection ring 11 connected to the towing rope 2. The adjusting cable 12 is operated by ground personnel. By controlling the adjusting cable 12, it is convenient to keep the rigid connection ring 11 stable, resist deflection under the action of wind, and facilitate the alignment and connection with the telescopic shaft 8.

[0038] For a further optimized solution, connecting members are rotatably connected to both ends of the beam body 15 respectively. One ends of the two connecting members away from the beam body 15 are rotatably connected to the two connecting frames 14 respectively.

[0039] During use, on the ground, the rigid connection ring 11 away from the towing rope 2 is placed into the through slot of the connecting frame 14, and the telescopic shaft 8 is extended into the rigid connection ring 11 through the air cylinder 5 to complete the hooking work of one end of the sling 13. The beam body 15 is lifted to a high altitude. The two connecting frames 14 are respectively located at both ends of the blade. At this time, the sling 13 is located below the blade. The towing rope 2 is lifted upward through the winch 1, thereby driving the rigid connection ring 11 to rise and gradually making the rigid connection ring 11 rise into the through slot. The ground personnel control the adjusting cable 12 to keep the rigid connection ring 11 stable. When the rigid connection ring 11 rises to be directly opposite to the position of the telescopic shaft 8, stop. Start the air cylinder 5 to drive the telescopic shaft 8 to extend into the rigid connection ring 11, thereby automatically completing the high-altitude hooking work of the other end of the sling 13.
