Description

Technical Field

[0001] This utility model relates to the technical field of ship rescue devices, specifically a ship rescue boarding structure. Background Technology

[0002] A rope ladder is a climbing tool, typically consisting of a series of horizontal bars (or steps) and longitudinal ropes. Flexible and easy to carry, it is primarily used to provide a vertical or inclined passage. In shipwreck rescue operations, rope ladders can be quickly deployed to help people climb overboard.

[0003] Existing rope ladders typically consist of two ropes and crossbars, with multiple crossbars installed between the two ropes to form a structure suitable for climbing. However, existing rope ladders still have the following shortcomings when used for water rescue:

[0004] Due to the flexibility of rope ladders and the instability of ships, people who fall into the water are prone to swaying during the climbing process, and the limited contact area between the person gripping the horizontal bar and the bar poses a high risk of slipping. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0033] Example:

[0034] Please see Figures 1-5 In this embodiment of the utility model, a ship rescue boarding structure includes a winding mechanism, which includes a U-shaped plate 1. A winding roller 4 is rotatably installed in the U-shaped plate 1. Both ends of the winding roller 4 rotatably pass through the U-shaped plate 1, and a handwheel 9 and a gear 12 are respectively fixedly installed at both ends of the winding roller 4. A locking component is fixedly installed on the outer side of the U-shaped plate 1 near the gear 12.

[0035] The top surface of the U-shaped plate 1 is fixedly equipped with a locking hook 2 for connecting with the ship railing 3;

[0036] The outer periphery of the take-up roller 4 is fixedly installed with partitions 5 on both sides near the U-shaped plate 1. A rope ladder structure is fixedly connected to the outer periphery of the take-up roller 4, and the rope ladder structure is located between the two partitions 5.

[0037] An auxiliary climbing mechanism is also fixedly connected to the periphery of the take-up roller 4.

[0038] The rope ladder structure includes two ropes 7 that are fixedly connected to the take-up roller 4. A base plate 10 is fixedly connected between the ends of the two ropes 7 away from the take-up roller 4. Multiple crossbars 8 are fixedly connected between the two ropes 7.

[0039] A counterweight 11 is fixedly installed on the bottom surface of the base plate 10. The counterweight 11 prevents the rope ladder from drifting with the waves and reduces swaying during climbing.

[0040] The auxiliary climbing mechanism includes two ropes 6 fixedly connected to the take-up roller 4. The two ropes 6 are located on the side of the two partitions 5 away from the second rope 7. The end of the rope 6 away from the take-up roller 4 is fixedly connected to the base plate 10. The partitions 5 separate the rope ladder from the auxiliary ropes to prevent entanglement.

[0041] A sliding sleeve 18 is fitted around the outer side of the rope 6, and a connecting plate 19 is fixedly connected between the two sliding sleeves 18. A binding strap 20 is fixedly installed on the outer side of the connecting plate 19.

[0042] Two sets of climbing components are fixedly installed on the top surface of the connecting plate 19.

[0043] The climbing component includes a rope 21 fixedly connected to the connecting plate 19. A handle 22 is fixedly connected to the end of the rope 21 away from the connecting plate 19. An anti-slip sleeve is installed around the handle 22.

[0044] A climbing hook 23 is fixedly installed at the end of the handle 22 away from the rope 3 21. A rubber layer 25 is provided on the inner side of the climbing hook 23. The rubber layer 25 can effectively increase the friction between the climbing hook 23 and the crossbar 8, thereby improving climbing stability.

[0045] When using this utility model:

[0046] The rope ladder is quickly connected to the ship's railing 3 via the locking hook 2, and the bolt 24 is tightened to prevent it from coming off. After unlocking the locking assembly, the handwheel 9 is turned to drive the winding roller 4, which simultaneously releases the rope ladder structure and auxiliary climbing mechanism. The counterweight 11 ensures that the rope ladder is lowered vertically to the water surface.

[0047] Next, rescuers descend the rope ladder and secure the drowning person's waist with straps 20. The drowning person grips handles 22 with both hands and uses climbing hooks 23 to alternately hook onto the horizontal bar 8 for stable climbing. Slippers 18 can slide along rope 6 to adapt to the movement requirements.

[0048] Among them, the strap 20 is linked with the climbing hook 23, so that even if the person falls into the water and loses their grip, they can remain suspended through the connecting plate 19, reducing the risk of falling into the water again.

[0049] The locking assembly includes a boss 15 fixedly installed on the outer side of the U-shaped plate 1. A screw 16 is threaded through the top surface of the boss 15. A knob 17 is fixedly installed at the top of the screw 16. A lifting plate 14 is rotatably connected to the bottom of the screw 16. The lifting plate 14 is located directly above the gear 12, and the lifting plate 14 is in sliding contact with the outer side of the U-shaped plate 1.

[0050] A rack 13 that works with the gear 12 is fixedly installed on the bottom surface of the lifting plate 14.

[0051] In the locking assembly, the rack 13 is controlled by the knob 17 to mesh with the gear 12, precisely locking the take-up roller 4 and preventing the rope ladder from swaying.

[0052] The meshing design of gear 12 and rack 13 enables instantaneous locking of the take-up roller 4, ensuring a fixed rope ladder length and adapting to the swaying environment of the ship.

[0053] The locking hook 2 has a through-threaded bolt 24 installed at its front end. The bolt 24 is used to control the opening and closing of the locking hook 2. The bolt 24 prevents the locking hook 2 from becoming detached from the railing 3.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
