Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a tiltable platform. Background Technology

[0002] During the desulfurization retrofit of a ship, space constraints arise. Due to the limited internal space and the requirement that the dimensions of the passageways used for the desulfurization retrofit meet the retrofit requirements, ensuring a clearance height of 1.8 meters for each platform, directly constructing platforms to meet the required clearance height would occupy a significant amount of space. This would not only increase the ship's production costs but also create difficulties for the design and installation of other components on the ship.

[0003] Therefore, we propose a reversible platform. Utility Model Content

[0018] Please see Figure 1-5This utility model provides a technical solution: a tiltable platform, including a support frame 1 and a platform 6. The support frame 1 has an upper fixed plate 2 at its top, with pulleys 3 on the upper fixed plate 2. A positioning plate 4 is located in the middle of the left side of the support frame 1, with a connecting shaft 5 at its left end, connecting to the right end of the platform 6. A fixing block 7 is located at the top of the platform 6, with a steel wire rope 8 connected to the top of the fixing block 7. A lower fixed plate 9 is located at the bottom of the support frame 1, with a take-up wheel 10 on the lower fixed plate 9. A connecting groove 11 is located at one end of the platform 6, with the connecting shaft 5 installed in the connecting groove 11. A positioning groove 12 is located at the bottom of the connecting shaft 5. A through hole 13 is located at the bottom left end of the positioning plate 4, and a positioning plate 14 is located at the bottom of the positioning plate 4. A threaded hole 15 is located in the middle of the positioning plate 14, with a bolt 16 installed in the threaded hole 15. The platform 6 is tilted up. A motor 20 drives a transmission shaft 18 to rotate via a reducer 19. The transmission shaft 18 carries... The rotating take-up reel 10 winds up the wire rope 8, pulling one end of the wire rope 8 to the fixing block, thereby lifting the platform 6. The platform 6 rotates within the mounting hole 17 via the connecting shaft 5 on the right end. After the platform 6 rotates upward 90 degrees, the motor 20 stops. At this time, the positioning groove 12 on the connecting shaft 5 rotates to the top of the through hole 13.
