DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1

[0023] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a turnover hook for a crane, including a fixing plate 1. A fixing hole is opened on one side of the fixing plate 1. A fixing rod 2 is slidably connected inside the fixing hole. One end of the fixing rod 2 is rotatably connected to a clamping shaft 3. A square groove is opened on one side of the clamping shaft 3. A pulling rope 4 is arranged on the outer surface of the clamping shaft 3. A sliding groove is opened on the outer surface of the fixing rod 2. A sliding block 5 is slidably connected inside the sliding groove. One end of the pulling rope 4 is fixedly connected to one side of the sliding block 5. A blocking block 6 is fixedly connected above the sliding block 5. A first spring 7 is fixedly connected inside the sliding groove. One end of the first spring 7 is fixedly connected to one side of the sliding block 5. A hook 16 is arranged on the outer surface of the fixing rod 2. A support hole is opened on one side of the fixing plate 1. A support rod 15 is arranged inside the support hole. A protective sleeve 18 is arranged on the outer surface of the support rod 15.

[0024] When it is necessary to disassemble the hook 16, rotate the connecting column 13, remove the connecting column 13 from the hook 16, then insert a tool into the square groove and rotate the clamping shaft 3. The clamping shaft 3 drives the pulling rope 4. The pulling rope 4 pulls the sliding block 5 and compresses the first spring 7. The sliding block 5 drives the blocking block 6 into the sliding groove, and then the fixing rod 2 can be pushed out of the fixing plate 1. When installing, the blocking block 6 enters the sliding groove under the action of an external force, and then the fixing rod 2 is inserted into the fixing hole of the fixing plate 1, facilitating the movement of the fixing rod 2 in the fixing hole.

[0025] Embodiment 2

[0026] Please refer to Figure 1 and Figure 4 , the present invention provides a technical solution: a turnover hook for a crane. A support block 8 is rotatably connected to one side of the fixing plate 1. A cavity is opened inside the support block 8. An electric push rod 9 is fixedly connected inside the cavity. One end of the electric push rod 9 is fixedly connected to a support plate 10 that is slidably connected inside the cavity. A second spring 11 is fixedly connected to one side of the support plate 10. One end of the second spring 11 is fixedly connected to a connecting plate 12 that is slidably connected inside the cavity. A connecting block 17 is fixedly connected to one side of the connecting plate 12. One side of the hook 16 is threadedly connected with a connecting column 13. A connecting groove adapted to the connecting column 13 is opened on one side of the connecting block 17. An adjustment switch 14 is arranged inside the cavity. The adjustment switch 14 is electrically connected to the electric push rod 9 through a wire. A control switch is arranged on one side of the hook 16. The control switch is electrically connected to the electric push rod 9 through a wire.

[0027] During use, the electric push rod 9 can be started by controlling the switch. The electric push rod 9 drives the support plate 10 to move. The support plate 10 compresses the second spring 11. The second spring 11 compresses the connecting block 17 through the connecting plate 12. The connecting block 17 drives the hook 16 to rotate around the fixed rod 2 through the connecting column 13, which can control the rotation of the hook 16 to a certain extent and facilitate hanging the ladle. When the hook 16 drives the ladle to rotate, the hook 16 will drive the connecting block 17 and the connecting plate 12 to move in the cavity of the support block 8 through the connecting column 13. The connecting plate 12 will compress the second spring 11. When the connecting plate 12 moves to a certain position, it will touch the adjustment switch 14. The adjustment switch 14 will control the electric push rod 9 to contract, so that the distance between the support plate 10 and the connecting plate 12 remains at an appropriate size, avoiding damage to the second spring 11 due to excessive compression.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
