[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Example:

[0026] Please combine Figure 1-5, a hook device for a wind power tower in this embodiment includes a hook body 1, the inner wall of the hook body 1 is plugged with a pin shaft 3, the surface of the pin shaft 3 is slidably connected with a hook connecting plate 2, the surface of the pin shaft 3 is slidably connected with a gasket 4, the inner wall of the pin shaft 3 is threadedly connected with an anti-falling pin 5, and the inner side of the hook body 1 is fixedly connected with a rubber plate 6. During the installation of the device, the hook connecting plate 2 is first hung on the crane hook, the hook connecting plate 2 is connected to the hook body 1 through the pin shaft 3, and is fixed with a gasket 4 and an anti-falling pin 5. After the hook is hooked, the contact area between the hook and the cylinder is protected by a rubber plate 6. The rubber plate 6 is installed in the area where the hook is in direct contact with the lifting object, which can better protect the lifting object from being scratched and avoid scratches. When in use, the hook can be directly hooked by lifting and lowering the hook and moving it left and right, thereby realizing efficient and convenient lifting operations.

[0027] There are two hook bodies 1, which are located at the left and right ends of the rubber plate 6. There are two hook connecting plates 2, which are located on the surface of the pin shaft 3 and are symmetrically arranged.

[0028] The washer 4 is located on the outside of the hook connecting plate 2 , and the anti-dropping latch 5 is located on the outside of the hook body 1 .

[0029] A fixed shaft 2 10 is fixedly connected to the inner side of the hook body 1, a tension spring 9 is provided on the surface of the fixed shaft 2 10, a fixed shaft 1 8 is provided at one end of the tension spring 9, both ends of the fixed shaft 1 8 are fixedly connected to a hanging plate 7, and a hanging shaft 12 is clamped on the inner wall of the hanging plate 7.

[0030] The second fixed shaft 10 is located above the hanging shaft 12 .

[0031] A rubber baffle 13 is fixedly connected to the inner wall of the hook body 1, and a fixed shaft three 11 is fixedly connected to the inner wall of the hook body 1. When the device is hung on the crane hook, the hanging plate 7 can be pulled outward to make the hanging plate 7 away from the hanging shaft 12, and the hanging plate 7 rotates on the surface of the fixed shaft three 11, and the fixed shaft three 11 is fixedly connected to the inner wall of the hook body 1. During the rotation, the tension spring 9 is stretched to limit it. The user can place the hook above the rubber plate 6 and release the hanging plate 7. Under the action of the tension spring 9, it can move obliquely downward, so that the inner wall of the hanging plate 7 contacts the surface of the hanging shaft 12, thereby getting stuck on the surface of the hanging shaft 12, and achieving the technical effect of automatic rebound.

[0032] The surface of the fixed shaft 3 11 is rotatably connected to the inner wall of the hanging plate 7 .

[0033] The implementation principle of a hook device for a wind turbine tower in the embodiment of the present application is as follows: the pin shaft 3 can be made of high-strength material, and is used in conjunction with a washer 4 and an anti-falling pin 5. The hook connecting plate 2 can be made of low-alloy high-strength steel, and the anti-falling pin 5 is designed with bolts and nuts, which is convenient for installation and disassembly. During the installation of the device, the hook connecting plate 2 is first hung on the crane hook and the hook connecting plate 2 is connected to the hook body 1 through the pin shaft 3, and is fixed with a washer 4 and an anti-falling pin 5. After the hook is hooked, the contact area between the hook and the cylinder is protected by a rubber plate 6. The rubber plate 6 is installed in the area where the hook is in direct contact with the hoisted object, which can better protect the hoisted object from being scratched and avoid scratches. The hook can be directly hooked by lifting and lowering the hook and moving it left and right, thereby achieving efficient and convenient lifting operations. The use of this design reduces the use of wire ropes and greatly saves costs. When the device is hung on the crane hook, the hanging plate 7 can be pulled outward to make the hanging plate 7 away from the hanging shaft 12. The hanging plate 7 rotates on the surface of the fixed shaft three 11, and the fixed shaft three 11 is fixedly connected to the inner wall of the hook body 1. During the rotation, the tension spring 9 is stretched to limit it. The user can place the hook above the rubber plate 6 and loosen the hanging plate 7. Under the action of the tension spring 9, it can move obliquely downward, so that the inner wall of the hanging plate 7 contacts the surface of the hanging shaft 12, thereby being stuck on the surface of the hanging shaft 12, achieving the technical effect of automatic rebound.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
