[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a displacement device for an operation beam of an offshore platform, including an offshore platform 1, a moving limit plate 2 is fixedly connected to the upper outer surface of the offshore platform 1, a support column 3 is movably connected to the upper outer surface of the moving limit plate 2, an operation platform beam 4 is fixedly connected to the upper outer surface of the support column 3, a moving component 5 is arranged between the support column 3 and the offshore platform 1, and a limiting component 6 is arranged between the support column 3 and the moving limit plate 2.
[0023] In this embodiment, as Figures 2-3 shown, the moving component 5 includes a fixed block 7, a first hydraulic cylinder 8, a first piston rod 9, a moving wheel 10, a connecting rod 11, a moving slide rail 12, a first through groove 13, a second hydraulic cylinder 14 and a second piston rod 15. There are two groups of moving limit plates 2 and four groups of support columns 3. Fixed blocks 7 are fixedly connected to both outer surfaces of the support column 3. A first hydraulic cylinder 8 is fixedly connected to the upper outer surface of the fixed block 7. A first piston rod 9 is movably connected to the lower outer surface of the first hydraulic cylinder 8. The first piston rod 9 penetrates through the lower outer surface of the fixed block 7. A moving wheel 10 is movably connected to the lower outer surface of the first piston rod 9. A connecting rod 11 is fixedly connected between the two first piston rods 9. A second piston rod 15 is movably connected to the outer wall of the connecting rod 11. The second piston rod 15 is movably connected to one end outer surface of the second hydraulic cylinder 14. The second hydraulic cylinder 14 is fixedly connected to the upper outer surface of the offshore platform 1. A moving slide rail 12 is opened on the upper outer surface of the offshore platform 1. There are four groups of moving slide rails 12. The moving slide rails 12 are located on both sides of the moving limit plate 2. The moving slide rails 12 are slidably connected to the moving wheels 10. A first through groove 13 is opened on one outer surface of the moving limit plate 2 and penetrates through the other outer surface. The second piston rod 15 penetrates through the front outer surface of the moving limit plate 2 and is slidably connected to the inner wall of the first through groove 13. The connecting rod 11 is slidably connected to the inner wall of the first through groove 13. By starting the first hydraulic cylinder 8, the first piston rod 9 descends to drive the moving wheel 10 into the interior of the moving slide rail 12. At this time, the support column 3 is supported and lifted, so that the U-shaped groove 18 is separated from the limit fixing groove 17. By starting the second hydraulic cylinder 14, the second piston rod 15 moves inside the first through groove 13 to push the connecting rod 11. Since the connecting rod 11 is connected to the first piston rod 9, when the connecting rod 11 moves, it drives the moving wheel 10 to slide inside the moving slide rail 12, thereby driving the operation platform beam 4 to move on the upper end of the offshore platform 1 for operation. When moving, the contact area with the offshore platform 1 can be reduced, the friction and resistance can be reduced, so that the operation platform beam 4 moves more stably and smoothly, and the damage to the operation platform beam 4 can be reduced.
[0024] In this embodiment, as Figures 3-4As shown in the figure, the limit component 6 includes a limit plate 16, a limit fixing groove 17, a U-shaped groove 18, a second through groove 19, a cavity 20, a double-headed motor 21, a threaded rod 22, a connecting moving block 23 and a limit insertion block 24. The limit plate 16 is fixedly connected to the upper outer surface of the moving limit plate 2. Multiple groups of limit fixing grooves 17 are provided on the outer surfaces of both sides of the limit plate 16. A U-shaped groove 18 is provided on the lower outer surface of the support column 3. The U-shaped groove 18 is adapted to the limit plate 16. Second through grooves 19 are provided on the outer surfaces of both sides of the inner wall of the U-shaped groove 18. A cavity 20 is provided inside the support column 3. The cavity 20 communicates with the second through groove 19. A double-headed motor 21 is fixedly connected to the inner wall of the cavity 20. Threaded rods 22 are movably connected to both ends of the double-headed motor 21. A connecting moving block 23 is threadedly connected to the outer wall of the threaded rod 22. A limit insertion block 24 is fixedly connected to the outer surface of one side of the connecting moving block 23. The limit insertion block 24 is inserted into the limit fixing groove 17. Start the double-headed motor 21 to drive the two threaded rods 22 to rotate. The threaded rods 22 are respectively a left-handed threaded rod and a right-handed threaded rod, driving the threaded rods 22 to move relatively, so that the limit insertion block 24 is inserted into the limit fixing groove 17, and the working platform beam 4 can be limited and fixed. It can quickly limit the working platform beam 4 when the working platform beam 4 stops moving, improving the stability of the working platform beam 4.
[0025] Working principle:
[0026] When a marine platform operation beam displacement device is in use, first separate the limit plug 24 from the limit fixing groove 17. By starting the double-headed motor 21, the two sets of threaded rods 22 rotate. The threaded rods 22 are respectively a left-handed threaded rod and a right-handed threaded rod, driving the threaded rods 22 to move in opposite directions. At this time, the connecting moving block 23 drives the limit plug 24 to separate from the limit fixing groove 17. Then, move the operation platform beam 4 through the moving component 5. By starting the first hydraulic cylinder 8, the first piston rod 9 descends to drive the moving wheel 10 into the inside of the moving slide rail 12. At this time, the support column 3 is supported and raised, so that the U-shaped groove 18 is separated from the limit fixing groove 17. Start the second hydraulic cylinder 14 to make the second piston rod 15 move inside the first through groove 13 to push the connecting rod 11. Since the connecting rod 11 is connected to the first piston rod 9, when the connecting rod 11 moves, it drives the moving wheel 10 to slide inside the moving slide rail 12, thereby driving the operation platform beam 4 to move on the upper end of the marine platform 1 for operation. During the movement, it can reduce the contact area with the marine platform 1, reduce friction and resistance, make the operation platform beam 4 move more stably and smoothly, and reduce the damage to the operation platform beam 4. When moving to the required position, the first hydraulic cylinder 8 retracts the first piston rod 9, and the first piston rod 9 drives the moving wheel 10 to rise. At this time, the support column 3 descends so that the U-shaped groove 18 is clamped with the limit fixing groove 17. Start the double-headed motor 21 to drive the two sets of threaded rods 22 to rotate. The threaded rods 22 are respectively a left-handed threaded rod and a right-handed threaded rod, driving the threaded rods 22 to move relatively, so that the limit plug 24 is inserted into the limit fixing groove 17, and the operation platform beam 4 can be limited and fixed. It can quickly limit the operation platform beam 4 when the operation platform beam 4 stops moving, improve the stability of the operation platform beam 4, and limit the operation platform beam 4, improve efficiency and reduce labor.
