Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a lifting device for offshore oil drilling, including a base plate 1, a support rod 2 fixedly installed on the outer surface of the base plate 1, and a top plate 3 fixedly installed at one end of the support rod 2. The base plate 1, support rod 2 and top plate 3 are all made of corrosion-resistant high-strength steel and have good structural strength. The base plate 1 and top plate 3 can be connected by the support rod 2, so that the base plate 1 and top plate 3 can form a stable support frame. A hoisting rope assembly 12 is installed on the outside of the top plate 3. The hoisting rope assembly 12 is mainly composed of a hook, a lug and a steel rope. When hoisting and lifting, one end of the hoisting rope assembly 12 is connected to the hook of the crane on the offshore platform. Then, when the workers move above the base plate 1, they can be lifted and moved.

[0029] A column 13 is fixedly installed on the outer surface of the base plate 1. One end of the column 13 is fixedly installed on the outer surface of the top plate 3. A limiting cylinder 14 is fixedly installed on the outer surface of the base plate 1. A positioning ring 15 is fixedly installed on the outer surface of the column 13. The column 13 can fix the middle position of the base plate 1 and the top plate 3. The limiting cylinder 14 is hollow inside, and the staff's luggage can be placed inside the limiting cylinder 14. The positioning ring 15 is arranged in a straight line on the outside of the column 13. The positioning ring 15 can assist the staff in grasping when moving, thereby improving safety.

[0030] A movable frame 4 is slidably connected to the outer surface of the support rod 2. A protective net 5 is fixedly installed on the outer surface of the movable frame 4. The movable frame 4 is located near the base plate 1. When the movable frame 4 moves, it can drive one end of the protective net 5 to move. The protective net 5 is woven from high-strength ropes. A circular protective structure can be formed by multiple sets of ring-arranged protective nets 5.

[0031] A fixed frame 9 is fixedly installed on the outer surface of the support rod 2. A second protective net 10 is fixedly installed on the outer surface of the fixed frame 9. A second movable frame 16 is slidably connected to the outer surface of the support rod 2. The upper and lower sides of the second movable frame 16 are fixedly installed with the first protective net 5 and the second protective net 10, respectively. The second movable frame 16 is located between the fixed frame 9 and the first movable frame 4. The first and second protective nets 5 and 10 can be connected through the second movable frame 16. When the first movable frame 4 moves down, it can drive the first protective net 5 and the second protective net 10 to open.

[0032] A connecting ring 6 is fixedly installed on the outer surface of the movable frame 4. Threaded rods 7 and 8 are threadedly connected to the inside of the connecting ring 6. The outer surface of threaded rod 7 is rotatably connected to the inside of the base plate 1, and the outer surface of threaded rod 8 is rotatably connected to the inside of the top plate 3. When the connecting ring 6 is threadedly connected to threaded rod 7, the movable frame 4 is fixed near the base plate 1, at which point protective nets 5 and 10 can be unfolded for protection. When the connecting ring 6 is threadedly connected to threaded rod 8, the movable frame 4 is fixed near the top plate 3, at which point protective nets 5 and 10 can be folded into the top plate 3 under the action of the movable frame 4 and the movable frame 16, facilitating the movement of personnel. Multiple sets of threaded rods 7 and 8 are symmetrically arranged, allowing the movable frame 4 to be fixed at multiple points, increasing its stability during use.

[0033] A fixing ring 11 is fixedly installed on the outer surface of the fixing frame 9. The outer surface of the threaded rod 8 is rotatably connected to the inside of the fixing ring 11. The fixing ring 11 can provide auxiliary support for one end of the threaded rod 8, increasing the stability of one end of the threaded rod 8.

[0034] A connecting ring 17 is fixedly installed on the outer surface of the movable frame 16. The connecting rings 16 and 2 are arranged symmetrically. A rotating rod 18 is fixedly installed at one end of the threaded rod 7. The other end of the rotating rod 18 is fixedly installed at one end of the threaded rod 8. The outer surface of the rotating rod 18 is sleeved with the inside of the connecting rings 16 and 2. The position of the movable frame 16 can be assisted and limited by the connecting ring 17. After the worker stands on the base plate 1, he can control the rotating rod 18 to rotate and disengage the threaded rod 8 from the connecting ring 6. Then, the movable frame 4 is pulled to move and the threaded rod 7 is connected to the connecting ring 6. The threaded connection between the connecting ring 6 and the threaded rod 7 can unfold the protective net 5 and the protective net 2 10 for protection. Conversely, the movable frame 4 can be moved to the position of the top plate 3.

[0035] Working principle: When in use, the operator stands above the base plate 1 and controls the rotating rod 18 to rotate. At this time, the threaded rod 2 8 will disengage from the connecting ring 1 6, pulling the moving frame 1 4 to the position of the base plate 1, so that the threaded rod 1 7 connects with the connecting ring 1 6. Through the connection of the threaded rod 1 7 and the connecting ring 1 6, the moving frame 2 1 6 and the moving frame 1 4 can be unfolded, and the protective net 1 5 and the protective net 2 10 can be unfolded. At this time, the protective net 1 5 and the protective net 2 10 can form external protection. After being lifted by the crane on the offshore platform, the overall basket can be moved. The operator can control the moving frame 1 4 to move again by controlling the rotating rod 18 inside. When the threaded rod 2 8 connects with the connecting ring 1 6, the protective net 1 5 and the protective net 2 10 can be folded.
