[0035] See also Figures 1-9 As shown, the present invention provides a technical solution:

[0036] A ship climbing device includes a mounting platform 1, one end of which is movably connected to multiple climbing ladders 3 via a first connecting assembly 2. The multiple climbing ladders 3 are sequentially connected via a second connecting assembly 4. Multiple pedals 5 are rotatably provided on the climbing ladders 3. Protective devices 6 are also slidably connected to both sides of the climbing ladders 3. A locking assembly 7 is also provided between the mounting platform 1 and the climbing ladders 3. The provision of the first connecting assembly 2 and the second connecting assembly 4 facilitates the rotation between the mounting platform 1 and the climbing ladders 3, facilitating the folding and storage of the ship climbing device. The locking assembly 7 secures the folded ship climbing device and allows it to be placed in a designated location for storage.

[0037] In this embodiment, the climbing ladder 3 is preferably three groups, including a first climbing ladder 31, a second climbing ladder 32, and a third climbing ladder 33 connected in sequence. The top of the first climbing ladder 31 is movably connected to one end of the mounting platform 1 through a first connecting component 2, and the bottom of the first climbing ladder 31 and the top of the second climbing ladder 32, as well as the bottom of the second climbing ladder 32 and the top of the third climbing ladder 33 are all movably connected through a second connecting component 4.

[0038] Furthermore, the first climbing ladder 31, the second climbing ladder 32, and the third climbing ladder 33 include symmetrically arranged fixed columns 34 and a plurality of pedals 5 arranged between the two fixed columns 34. The bottom ends of the fixed columns 34 of the first climbing ladder 31 and the second climbing ladder 32 and the top ends of the fixed columns 34 of the second climbing ladder 32 and the third climbing ladder 33 are provided with snap-in grooves 35, and the top ends of the two fixed columns 34 of the first climbing ladder 32 are provided with adjustment columns 36.

[0039] In this embodiment, the first connecting assembly 2 includes a first connecting post 21, with connecting ears 22 symmetrically provided at both the upper and lower ends of the first connecting post 21. A first through-hole 11 is formed through one end of the mounting platform 1 and the middle of the adjustment post 36. A rotating rod 12 is movably disposed within the first through-hole 11. Both ends of the rotating rod 12 extend outside the first through-hole 11 and are rotatably connected to the inner sides of the connecting ears 22 via bearings. A locking member 23 is also provided between the connecting ears 22, one end of the mounting platform 1, and the adjustment post 36. By rotating the rotating rod 12 within the first through-hole 11, the angle between the mounting platform 1 and the first climbing ladder 31 can be adjusted using the first connecting assembly 2. During installation, the mounting platform 1 is fixed to the hull, and the angle between the mounting platform 1 and the first climbing ladder 31 is adjusted according to the hull structure. The present invention utilizes the locking member 23 to fix the angle between the mounting platform 1 and the first climbing ladder 31, thereby improving the stability of the vessel climbing device.

[0040] As a preferred implementation of this embodiment, the locking member 23 includes a first locking ring 231, a second locking ring 232, a sleeve 233, and a locking plate 234. The first locking ring 231 is fixedly mounted on one end of the mounting platform 1 and on both sides of the top of the first climbing ladder 31. The sleeve 233 is movably sleeved on the outside of the rotating rod 12. An annular hole 221 for the sleeve 233 to pass through is opened on the connecting ear 22. One end of the sleeve 233 is fixedly connected to the second locking ring 232, and the other end passes through The annular hole 221 is fixedly connected to the locking plate 234. A second through hole 235 is provided in the middle of the first locking ring 231 and the second locking ring 232 for the rotating rod 12 to pass through. An annular tooth 236 is provided on the side opposite to the first locking ring 231 and the second locking ring 232. A first compression spring 237 is sleeved on the outside of the sleeve 233. The two ends of the first compression spring 237 are respectively fixedly connected to the second locking ring 232 and the connecting ear 22. A pull ring 238 is connected to the outside of the locking plate 234.

[0041] When it is necessary to use the first connecting component 2 to adjust the angle between the mounting platform 1 and the first climbing ladder 31, after the mounting platform 1 is fixedly installed on the hull, the angle between the mounting platform 1 and the first connecting component 2 is first adjusted, and the pull rings 28 on both sides are pulled to drive the second locking ring 232 to move toward the connecting ear 22 through the sleeve 233. The first compression spring 237 is compressed, and the second locking ring 232 is separated from the first locking ring 231. The first connecting component 2 is rotated to the desired angle, and then the pull rings 238 on both sides are released. The first compression spring 237 is reset, and the second locking ring 232 and the first locking ring 231 are engaged and locked by the annular teeth 236, thereby fixing the angle between the mounting platform 1 and the first connecting component 2; and then the angle between the first connecting component 2 and the first climbing ladder 31 is adjusted in the same way to achieve the purpose of adjusting the angle between the mounting platform 1 and the first climbing ladder 31. No further details are given here.

[0042] In this embodiment, the second connecting component 4 includes a second connecting column 41, which is hollow inside. Arc-shaped sliding grooves 411 are symmetrically provided on the upper and lower sides of the second connecting column 41, and fixed plates 412 are provided on both sides of the sliding groove 411. The bottom ends of the fixed columns 34 of the first climbing ladder 31 and the second climbing ladder 32 and the top ends of the fixed columns 34 of the second climbing ladder 32 and the third climbing ladder 33 are all integrally formed and connected with a semicircular rotating column 341. A clamping groove 35 is opened in the middle of the rotating column 341, and the rotating column 341 is rotatably set between the two fixed plates 412. The rotating column 341 is rotated between the two fixed plates 412, which facilitates the rotation between the first climbing ladder 31 and the second climbing ladder 32, and the second climbing ladder 32 and the third climbing ladder 33, so as to facilitate folding and storage; the arc-shaped slide groove 411 is preferably a quarter arc, which can limit the rotation of the first climbing ladder 31, the second climbing ladder 32, and the third climbing ladder 33, so that the maximum rotation angle is 90°, that is, perpendicular or parallel to the second connecting column 41, which facilitates the overall stability of the device after folding, and also facilitates determining the position when connected after unfolding.

[0043] Furthermore, fixed components 42 are symmetrically provided on both sides of the second connecting column 41, and the fixed components 42 include a first motor 421, a telescopic rod 422, a connecting seat 423, a connecting rod 424, and a push-pull plate 425. The first motor 421 is fixedly provided on the outside of the second connecting column 41, and the output end of the first motor 421 passes through the side wall of the second connecting column 41 and is fixedly connected to the telescopic rod 422. The other end of the telescopic rod 422 is fixedly connected to the connecting seat 423, and the upper and lower ends of the connecting seat 423 are symmetrically connected to the connecting rod 424 for rotation. The other end of the connecting rod 424 is rotatably connected to the push-pull plate 425. A third through hole 4111 is provided on the slide 411, and a fixed groove 4112 connected to the third through hole 4111 is provided on the inner side of the second connecting column 41. The push-pull plate 425 is movably provided in the fixed groove 4112, and the fixed groove 4112 is provided corresponding to the clamping groove 35.

[0044] During use, the first motor 421 controls the telescopic rod 422 to extend and push the connecting seat 423 away from the first motor 421. The connecting rod 424 pushes the push-pull plate 425 to move away from the fixing slot 4112. The push-pull plate 425 passes through the third through-hole 4111 in the slide slot 411 and enters the engaging slot 35 to engage and secure it. This secures the first climbing ladder 31 to the second climbing ladder 32, and the second climbing ladder 32 to the third climbing ladder 33 via the second connecting assembly 4. After use, the first motor 421 controls the telescopic rod 422 to compress, driving the push-pull plate 425 to return to its original position, allowing the first, second, and third climbing ladders 31, 32, and 33 to be folded and stored.

[0045] In this embodiment, the stepping plate 5 includes a fixed frame 51 and a connecting post 52. The connecting posts 52 are symmetrically connected to both sides of the fixed frame 51, and the other ends of the connecting posts 52 are fixedly connected to the fixed posts 34. A gripping rod 53 is provided on one side of the fixed frame 51, and multiple anti-slip plates 54 are fixedly installed inside the fixed frame 51. The edges of the anti-slip plates 54 are provided with anti-slip grooves 541. The design of the gripping rod 53 facilitates gripping during climbing, and the anti-slip plates 54 increase friction between the climbing plate 5 and the climbing plate 5, preventing the climber from stepping on empty space and improving safety.

[0046] In this embodiment, in order to further improve the safety of climbing, the protection device 6 includes a protection belt 61 that is slidably arranged on both sides of the first climbing ladder 31, the second climbing ladder 32, and the third climbing ladder 33, respectively. The two ends of the protection belt 61 are respectively connected to T-blocks 62 by chains, and a T-slot 63 is provided on the fixed column 34. The T-block 62 is slidably arranged in the T-slot 63. A connecting ring 64 is fixedly provided in the middle of the protection belt 61. Three groups of rotating rollers 14 are installed on the mounting platform 1 through the fixing frame 13. A connecting rope 15 is wrapped around the rotating roller 14. One end of the connecting rope 15 is fixed to the rotating roller 14, and the other end is fixedly connected to the connecting ring 64 of the protection belt 61. A second motor 16 is installed at one end of the fixing frame 13. The output end of the second motor 16 is fixedly connected to the rotating roller 14. A plurality of mounting holes 17 are also provided on the mounting platform 1.

[0047] It is worth noting that the protective belt 61 in this technical solution can be any belt that can be adjusted in length and fastened to the waist of a person in the prior art, and no special restrictions are imposed here. During the climbing process, the person fastens the protective belt 61 to the waist, and the T-block 62 slides along the T-slot 63. Even if the person misses the step 5, the protective belt 61, T-block 62, and T-slot 63 can cooperate to protect the person and prevent him from falling. Take the example of a person climbing from the third climbing ladder 33 to the second climbing ladder 32: the person first fastens the protective belt 61 on the third climbing ladder 33 to the waist, and then climbs up. When climbing to the top of the third climbing ladder 33, the person first fastens the protective belt 61 on the second climbing ladder 32 to the waist, and then loosens the protective belt 61 on the third climbing ladder 33. In this way, the person can continue to climb upward, reduce the risk of falling, and improve safety.

[0048] Furthermore, before use, one end of the connecting rope 15 needs to be fixed to the connecting rings 64 on the three protective belts 61 respectively. During the climbing process, the second motor 16 can be used to control the rotation of the rotating roller 14 to reel in the connecting rope 15. This not only further improves the safety of the protective belt 61 and reduces the risk of falling, but also can use the connecting rope 15 to provide a certain upward pulling force to reduce the resistance of the person during the climbing process. It is especially suitable for people who fall into the water and are physically exhausted during the rescue process.

[0049] In this embodiment, the locking assembly 7 includes locking threaded holes 71 and locking rods 72 symmetrically arranged on either side of the mounting platform 1. The locking threaded hole 71 is provided on one side of the mounting platform 1, and the locking rod 72 is pivotally mounted outside the fixing post 34 of the third climbing ladder 33. A fourth through-hole 73 is defined at one end of the locking rod 72. When the locking rod 72 is pivoted toward the mounting platform 1, the fourth through-hole 73 aligns with the locking threaded hole 71. A rolling wheel 342 is also provided at the bottom of the fixing post 34 of the third climbing ladder 33. After the first, second, and third climbing ladders 31, 32, and mounting platform 1 are folded, the locking rod 72 is rotated to align the fourth through-hole 73 with the locking threaded hole 71. The ladders are then secured with fastening bolts to prevent loosening. The rolling wheel 342 facilitates movement of the ladders to a designated location for storage.

[0050] When using the ship climbing device of this embodiment, the device is taken out from the designated position, the fastening bolts are removed, the first climbing ladder 31, the second climbing ladder 32, and the third climbing ladder 33 are opened, the free ends of the connecting rope 15 are fixedly connected to the connecting rings 64 on the three protective belts 61, and the first climbing ladder 31 and the second climbing ladder 32, and the second climbing ladder 32 and the third climbing ladder 33 are fixed by the second connecting assembly 4;

[0051] The mounting platform 1 is fixedly mounted on the hull through the mounting holes 17;

[0052] Adjust the angle between the first climbing ladder 31 and the mounting platform 1 through the first connecting assembly 2 and fix them through the locking member 23;

[0053] The person first fastens the protective belt 61 on the third climbing ladder 33 around the waist, then climbs upward. When climbing to the top of the third climbing ladder 33, the person first fastens the protective belt 61 on the second climbing ladder 32 around the waist, then loosens the protective belt 61 of the third climbing ladder 33 and continues to climb upward. The person climbs to the top of the first climbing ladder 31 in the same way, and loosens the protective belt 61 of the first climbing ladder 31 after climbing onto the hull.

[0054] During the climbing process, the second motor 16 controls the rotation of the rotating roller 14 to reel in the connecting rope 15, which not only further improves the safety of the protective belt 61 and reduces the risk of falling, but also uses the connecting rope 15 to provide a certain upward pulling force to reduce the resistance of the person during the climbing process;

[0055] After use, the first climbing ladder 31 , the second climbing ladder 32 , and the third climbing ladder 33 are folded and stored together with the installation platform 1 , and are fixed by the locking assembly 7 and moved to a designated position for storage.
