Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable guide technology, specifically to an adjustment structure and a marine roller cable guide. Background Technology
[0002] As a core component of ship mooring systems, roller guides play a crucial role in ensuring operational safety and efficiency thanks to their scientifically designed structure and flexible adjustment capabilities. Through a combination of vertical and horizontal rollers, they create a multi-directional guide structure that precisely guides cables from any direction, effectively reducing friction and wear between the cable and the equipment. This significantly improves the stability of the guide process, fully meeting the practical needs of complex sea conditions and diverse mooring scenarios.
[0003] In ship mooring operations, the diameter of the cable used varies depending on the ship's tonnage, mooring environment, and operational requirements. However, current roller guide designs have limitations, with fixed vertical and horizontal roller spacing. This design results in two problems: excessively thin cables will deviate due to excessive roller gaps, affecting guiding accuracy; excessively thick cables will squeeze the rollers due to insufficient gaps, accelerating wear and shortening the equipment's lifespan. Utility Model Content

[0021] 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.
[0022] Please see Figure 1-6 An adjustable structure and a marine roller guide include a movable frame 11 and a sliding frame 4 mounted on a guide bracket 1. The upper end of the guide bracket 1 is provided with an anti-detachment groove 3, and the sliding frame 4 is slidably connected inside the anti-detachment groove 3. The end of the sliding frame 4 is rotatably connected with a movable horizontal roller 5. A threaded rod 6 is threadedly connected to the middle position of the sliding frame 4. A first handwheel 7 is fixedly connected to the upper end of the threaded rod 6, and the lower end of the threaded rod 6 is rotatably connected to the guide bracket 1. A double-acting screw 13 is rotatably connected to the upper end of the movable frame 11. Threaded blocks 18 are threadedly connected to both ends of the double-acting screw 13. A second handwheel 14 is fixedly connected to the end of the double-acting screw 13. A rotating shaft 16 is fixedly connected to the bottom of the threaded block 18, and a vertical roller 15 is sleeved on the outside of the rotating shaft 16.
[0023] The adjustment structure and marine roller guide of this utility model allow for easy adjustment of the distance between the fixed horizontal roller 2 and the movable horizontal roller 5. Simply rotate the threaded rod 6 via the first handwheel 7, and the sliding frame 4, threaded to the threaded rod 6, will move up and down along the anti-detachment groove 3, thereby changing the distance between the movable horizontal roller 5 and the fixed horizontal roller 2. Simultaneously, when adjusting the distance between the two vertical rollers 15, simply rotate the double-acting screw 13 via the second handwheel 14, and the two threaded blocks 18, threaded to the double-acting screw 13, will move synchronously. The threaded blocks 18 will then drive the vertical rollers 15 to move simultaneously via the rotating shaft 16, thus adjusting the distance between the two vertical rollers 15. This structure makes the adjustment process of the movable horizontal roller 5 and the two vertical rollers 15 simple, convenient, and easy to operate.
[0024] like Figure 3 , Figure 4 and Figure 6As shown, a slider 17 is fixedly connected to the bottom of the rotating shaft 16, and a slide rod 12 is slidably connected to the middle position of the slider 17. The two ends of the slide rod 12 are fixedly connected to the moving frame 11. The upper and lower ends of the inner side of the cable guide bracket 1 are provided with slots 19. The slider 17 matches the slot 19 at the lower end of the cable guide bracket 1, and the threaded block 18 matches the slot 19 at the upper end of the cable guide bracket 1.
[0025] Specifically, after the vertical roller 15 is adjusted, the movable frame 11 can be pushed so that the threaded block 18 and the slider 17 are respectively inserted into the slots 19 at the upper and lower ends of the cable guide bracket 1, thereby restricting the vertical roller 15, improving the stability of the connection between the vertical roller 15 and the cable guide bracket 1, and preventing the vertical roller 15 from shifting during use.
[0026] It is worth noting that although ships may select "sufficiently safe and not overly redundant" cable specifications based on tonnage to save costs, resulting in the use of different cable specifications when the ship is unloaded and fully loaded, the selected cable specifications are still limited to a specific range, and the cables themselves have a fixed specification series. Therefore, when adjusting the vertical roller 15, for cables of the same specification, the vertical roller 15 will be fixed in the same position, so only one slot 19 needs to be set for the several commonly used cable specifications of the ship.
[0027] like Figure 4 As shown, the upper end of the movable frame 11 has an insertion hole 25, and an insertion block 26 is slidably connected inside the insertion hole 25. The position of the insertion hole 25 matches the position of the card slot 19.
[0028] Specifically, each socket 25 is matched with the slot 19. After the plug 26 is inserted into the socket 25, the plug 26 will restrict the threaded block 18 to facilitate the alignment of the threaded block 18 with the slot 19.
[0029] like Figure 3 As shown, limit grooves 8 are provided on both sides of the cable guide bracket 1. Limit blocks 9 are slidably connected inside the limit grooves 8. The end of the limit block 9 is fixedly connected to the moving frame 11. An anti-detachment block 10 is fixedly connected to the end of the limit block 9 away from the moving frame 11.
[0030] Specifically, the limiting block 9 makes the connection between the moving frame 11 and the cable guide bracket 1 more stable, and the anti-detachment block 10 makes it difficult for the limiting block 9 to detach from the cable guide bracket 1, thus preventing the moving frame 11 from separating from the cable guide bracket 1.
[0031] like Figure 1 , Figure 3 and Figure 5As shown, both ends of the cable guide bracket 1 are provided with positioning grooves 20. A positioning block 21 is slidably connected inside the positioning groove 20. A positioning plate 22 is fixedly connected to one side of the positioning block 21. A fixing bolt 24 is slidably connected to the middle position of the positioning plate 22. The end of the fixing bolt 24 is threadedly connected to the cable guide bracket 1.
[0032] Specifically, when the moving frame 11 is in motion, after the threaded block 18 and the slider 17 are inserted into the slot 19, the positioning plate 22 can be inserted between the anti-detachment block 10 and the cable guide bracket 1, thereby preventing the moving frame 11 from moving.
[0033] like Figure 3 and Figure 5 As shown, a magnetic block 23 is fixed to the lower end of the positioning plate 22, and a chamfer is provided on the lower end of the positioning plate 22 on the side away from the moving frame 11.
[0034] Specifically, the magnetic block 23 has a pre-fixing effect and a chamfer, which makes it easier for the positioning plate 22 to be inserted between the anti-detachment block 10 and the cable guide bracket 1.
[0035] This utility model also provides a marine roller guide, including the above-mentioned adjustment structure, wherein a fixed horizontal roller 2 is rotatably connected to the lower end of the guide bracket 1 near the movable horizontal roller 5.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
