[0029] A plurality of limit rods 21 are arranged on the top surface of the plate body 11 of the second sling 2, and a limit groove 31 is provided on the bottom surface of the connecting plate 3. The upper end of the limit rod 21 is located in the limit groove 31 and slidably cooperates with the inner wall of the limit groove 31. When the motor 4 drives the connecting column 5 to rotate, the connecting sleeve 6 drives the second sling 2 to rotate synchronously. At this time, the limit rod 21 cooperates with the limit groove 31 to increase the stability of the second sling 2 during rotation.

[0030] A motor 4 is fixedly arranged on the top surface of the connecting plate 3, and a connecting column 5 is vertically inserted into the bottom surface of the connecting plate 3. The rotating shaft of the motor 4 is inserted into the connecting plate 3 and fixedly connected to the upper end of the connecting column 5, so that the connecting column 5 can be rotated conveniently through the motor 4; a connecting sleeve 6 is movably arranged on the lower end of the connecting column 5, and a slot 51 adapted to the connecting sleeve 6 is provided at the top of the connecting column 5, the connecting sleeve 6 is inserted upward into the slot 51, and the slot 51 is connected with the movable groove 8, and a bearing 52 is fixedly arranged at the connection between the bottom surface of the connecting plate 3 and the connecting column 5, and the connecting column 5 is fixedly arranged in the bearing 52, so that the connecting column 5 and the connecting sleeve 6 can be conveniently connected together through the slot 51, and the driving force required for the motor 4 to drive the connecting column 5 to rotate is reduced through the bearing 52.

[0031] A locking sleeve 7 is provided on the movable sleeve of the connecting column 5, and the connecting sleeve 6 is fixedly arranged on the top of the second sling 2. The second sling 2 is movably connected with the connecting plate 3 through the connecting sleeve 6 and the connecting column 5. Specifically, a blocking ring is provided on the lower end fixed sleeve of the outer wall of the connecting column 5, which facilitates blocking the locking sleeve 7 and reduces the possibility of separation of the locking sleeve 7 and the connecting column 5. First, the connecting plate 3 is hung on the first sling 1, and then the connecting sleeve 6 is inserted into the connecting column 5, and then the locking sleeve 7 is rotated to thread it together with the connecting sleeve 6.

[0032] The outer wall of the connecting column 5 is provided with a plurality of movable grooves 8 along the circumference, and a positioning rod 9 is movably provided in the movable groove 8, and the positioning rod 9 is conveniently assembled through the movable groove 8; when the locking sleeve 7 moves downward, the positioning rod 9 is pushed to move so that the positioning rod 9 is plugged into the connecting sleeve 6. The connecting sleeve 6 includes an externally threaded tube 61 and an insertion rod 62. The bottom of the externally threaded tube 61 is fixedly connected to a bottom plate 63, and the insertion rod 62 is fixedly arranged on the top of the connecting plate 3 and is coaxially arranged with the externally threaded tube 61. The externally threaded tube 61 is movably sleeved on the lower end of the connecting column 5, and the upper end of the insertion rod 62 is inserted into the slot 51. Therefore, the outer wall of the upper end of the insertion rod 62 is provided with a positioning groove 64 corresponding to the positioning rod 9 along the circumference. When the operator assembles the connecting sleeve 6 and the connecting column 5 together, the insertion rod 62 is inserted into the slot 51, and the externally threaded tube 61 is sleeved on the connecting column 5. Then, by rotating the locking sleeve 7, the locking sleeve 7 and the externally threaded tube 61 are threadedly connected together.

[0033] The bottom surface of the locking sleeve 7 is recessed upward to form an internal thread groove 71 that matches the external thread tube 61. The locking sleeve 7 is threadedly connected to the external thread tube 61. When the operator rotates the locking sleeve 7, the internal thread groove 71 cooperates with the external thread tube 61 to facilitate fixing the external thread tube 61 on the connecting column 5.

[0034] One end of the positioning rod 9 inserted into the movable groove 8 is fixedly sleeved with a ring 91, and one end of the positioning rod 9 inserted into the movable groove 8 is sleeved with a spring 92. One end of the spring 92 is fixedly connected to the ring 91, and the other end of the spring 92 is fixedly connected to the inner wall of the movable groove 8. The positioning rod 9 passes through the movable groove 8 and is inserted into the positioning groove 64. When the locking sleeve 7 moves downward, it conflicts with the positioning rod 9 and pushes the positioning rod 9 to move and insert into the positioning groove 64. At this time, the positioning rod 9 drives the ring 91 to move and causes the spring 92 to compress and deform. When the locking sleeve 7 is separated from the positioning rod 9, the positioning rod 9 loses its thrust. At this time, the spring 92 recovers its deformation to push the ring 91 and the positioning rod 9 to move and separate from the positioning groove 64. At this time, the insertion rod 62 and the external threaded tube 61 both lose their limit, which facilitates the operator to disassemble the second hoist 2.

[0035] Working principle: When using the steel slag basin rotating hanger, first hang the connecting plate 3 on the first hanger 1, then insert the connecting sleeve 6 into the connecting column 5, and then rotate the locking sleeve 7 to thread it together with the connecting sleeve 6, and when the locking sleeve 7 moves down, it contacts the positioning rod 9, so that the positioning rod 9 moves and plugs into the connecting sleeve 6 for secondary fixation, so that the second hanger 2 is more stable when connected to the connecting plate 3;

[0036] The motor 4 drives the connecting column 5 to rotate and makes the connecting sleeve 6 drive the second sling 2 and the slag basin to rotate synchronously, so as to adjust the direction of the slag basin. When the second sling 2 needs to be disassembled and repaired, the locking sleeve 7 is rotated to separate it from the connecting sleeve 6, and the locking sleeve 7 is separated from the positioning rod 9. At this time, the positioning rod 9 loses its thrust and resets to separate from the connecting sleeve 6, thereby causing the connecting sleeve 6 to lose its limit, which makes it easier for the operator to separate the connecting sleeve 6 from the connecting column 5 and realize the disassembly of the second sling 2. Therefore, it is more convenient to disassemble and repair the second sling 2.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
