Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4This utility model provides a technical solution: an underwater equipment lifting device, including a ring frame 1, a support frame 2 installed inside the ring frame 1, a rotating hanger 3 rotatably connected to the top of the support frame 2, a frame 4 installed on the top of the rotating hanger 3, a winding roller 5 rotatably connected inside the frame 4, a lifting rope 8 wound around the outside of the winding roller 5, a hook 9 installed at one end of the lifting rope 8, a first self-locking motor 27 installed on one side of the frame 4, the output end of the first self-locking motor 27 being fixedly connected to the winding roller 5 via a coupling, driving the winding roller 5 to rotate, controlling the winding and unwinding of the lifting rope 8, thereby adjusting the height of the hook 9 for easy lifting of the equipment, a guide wheel 6 cooperating with the lifting rope 8 installed at one end of the rotating hanger 3, the lifting rope 8 passing around the guide wheel 6 for easy adjustment of the lifting rope. 8. Guide frames 21 and protective shells 7 are respectively installed on the top of the rotating hanger 3 and on both sides adjacent to the frame 4. Guide rods 22 are sleeved on the outer side of the guide frames 21, and guide rings 23 are installed on the top of the guide rods 22. A limit frame 24 is fixedly connected to one side of the guide ring 23. A turntable 25 is rotatably connected to one side of the protective shell 7. A guide roller 26 is installed on one side of the turntable 25. One end of the guide roller 26 passes through the limit frame 24, so that the guide roller 26 revolves with the rotation of the turntable 25 and pushes the limit frame 24 and the guide ring 23 to repeatedly shift. The guide ring 23 limits the suspension rope 8, so that the suspension rope 8 can be evenly unfolded or wound on the winding roller 5. The first support shaft 28 and the second support shaft 29 are rotatably connected inside the protective shell 7. A first bevel gear 30 and a second bevel gear 31 are respectively installed at one end of a support shaft 28 and a second support shaft 29. The first bevel gear 30 and the second bevel gear 31 mesh with each other. The first support shaft 28 and the second support shaft 29 are fixedly connected to the winding roller 5 and the turntable 25, respectively. Through the meshing between the first bevel gear 30 and the second bevel gear 31, the turntable 25 is driven by the frame 4 and can rotate with the rotation of the winding roller 5. The rotating hanger 3 has a sliding groove 10 inside. A limit rod 11 is slidably connected inside the sliding groove 10. A limit ring 14 is fixedly connected to one end of the limit rod 11. The hanging rope 8 passes through the limit ring 14. A rack 13 is installed on the top of the limit rod 11. A rotating gear is rotatably connected inside the sliding groove 10 and at the top of the rack 13. A first gear 16 is installed at one end of a roller 15, which meshes with a rack 13. Rotation of the first gear 16 pushes the rack 13 and the limiting rod 11 to move. A limiting ring 14 at one end of the limiting rod 11 then pushes one end of the lifting rope 8 to move a corresponding distance, facilitating further adjustment of the hook 9's position to align it with the underwater equipment. A rotating shaft 32 is rotatably connected inside the support frame 2, with one end fixedly connected to the rotating frame 3. A second self-locking motor 12 and a third self-locking motor 17 are respectively installed at the bottom of the support frame 2 and one side of the rotating frame 3. The output ends of the second and third self-locking motors 12 and 17 are fixedly connected to the rotating shaft 32 and roller 15 respectively via couplings, driving the rotating shaft 32 and roller 15 to rotate.The rotating frame 1 provides power for the rotation of the rotating hanger 3 and the first gear 16. An annular groove 18 is provided on the outer side of the annular frame 1. Auxiliary rods 19 are installed on both sides of the bottom of the rotating hanger 3. A pulley 20 is rotatably connected to one end of the auxiliary rod 19, located inside the annular groove 18. This assists in supporting and rotating the rotating hanger 3 while reducing friction with the annular groove 18. The auxiliary rod 19 includes a first rod body 191, with a movable groove 192 inside. A second rod body 193 is slidably connected inside the movable groove 192. A telescopic spring 194 is fixedly connected between the second rod body 193 and the movable groove 192. Through the deformation of the telescopic spring 194, the second rod body 193 can push the pulley 20 against the annular groove 18. When encountering obstruction from objects attached to the annular groove 18, the pulley 20 can automatically shift and maintain contact with the annular groove 18.

[0018] In summary, during use, the second self-locking motor 12 drives the rotating frame 3 to rotate via the rotating shaft 32, causing the rotating frame 3 to revolve. As the hook 9 at one end of the lifting rope 8 approaches the underwater equipment, the pulleys 20 at one end of the two auxiliary rods 19 at the bottom of the rotating frame 3 slide in the annular groove 18 within the annular frame 1. Simultaneously, the third self-locking motor 17 drives the rotating roller 15 in the sliding groove 10 within the rotating frame 3 to rotate. Since the first gear 16 at one end of the rotating roller 15 meshes with the rack 13 on the limiting rod 11, and the lifting rope 8 passes through the limiting ring 14 at one end of the limiting rod 11, the first gear 16 rotates and pushes the rack 13 and the limiting rod 11 to move. The limiting ring 14 then moves one end of the lifting rope 8, adjusting the hook. After the hook 9 is aligned with the underwater equipment, the first self-locking motor 27 drives the winding roller 5 to rotate, causing the hoisting rope 8 to unfold to the corresponding length. The hook 9 is then fixed to the underwater equipment. Since the hoisting rope 8 passes through the sliding guide ring 23 on the guide frame 21, and the guide roller 26 on the turntable 25 passes through the limiting frame 24 on one side of the guide ring 23, and the first bevel gear 30 and the second bevel gear 31 inside the protective shell 7 drive the winding roller 5 and the turntable 25 through meshing, the turntable 25 rotates accordingly, causing the guide roller 26 to revolve. The guide roller 26 slides within the limiting frame 24 and pushes the limiting frame 24 and the guide ring 23 to move. The guide ring 23 then drives the hoisting rope 8 to move repeatedly, so that the hoisting rope 8 is evenly unfolded or wound on the winding roller 5.
