When installing, the installation platform 1 is fixedly installed on the hull, and the angle between the installation platform 1 and the first climbing ladder 31 is adjusted according to the hull structure. The present invention uses the locking member 23 to fix the angle between the installation platform 1 and the first climbing ladder 31, thereby improving the stability of the ship climbing device.

[0029] 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. The connecting ear 22 is provided with an annular hole 221 for the sleeve 233 to pass through.

[0030] 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, first adjust the angle between the mounting platform 1 and the first connecting component 2, pull the pull rings 28 on both sides, and drive the second locking ring 232 to move toward the connecting ear 22 through the sleeve 233, the first compression spring 237 is compressed, the second locking ring 232 is separated from the first locking ring 231, the first connecting component 2 is rotated to the required 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, so as to fix the angle between the mounting platform 1 and the first connecting component 2; and then use the same method to adjust the angle between the first connecting component 2 and the first climbing ladder 31, so as to achieve the purpose of adjusting the angle between the mounting platform 1 and the first climbing ladder 31, which will not be repeated here.

[0031] In this embodiment, the second connecting component 4 includes a second connecting column 41, which is hollow inside. The second connecting column 41 is symmetrically provided with arc-shaped sliding grooves 411 on the upper and lower sides, 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. By rotating the rotating column 341 between the two fixed plates 412, the first climbing ladder 31 and the second climbing ladder 32, and the second climbing ladder 32 and the third climbing ladder 33 can be rotated 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.

[0032] Furthermore, fixed components 42 are symmetrically arranged 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 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 rotatably connected to the connecting rod 424. The other end of the connecting rod 424 is rotatably connected to the push-pull plate 425. A third through hole 4111 is opened on the slide groove 411, and a fixed groove 4112 connected to the third through hole 4111 is arranged on the inner side of the second connecting column 41, and the push-pull plate 425 is movably arranged in the fixed groove 4112, and the fixed groove 4112 is arranged corresponding to the clamping groove 35.

[0033] When in use, the first motor 421 is used to control the telescopic rod 422 to stretch and push the connecting seat 423 to move away from the first motor 421, and the connecting rod 424 pushes the push-pull plate 425 to move in opposite directions along the fixing groove 4112, and passes through the third through hole 4111 on the slide groove 411 to enter the clamping groove 35 and clamp and fix it, so that the first climbing ladder 31 and the second climbing ladder 32, and the second climbing ladder 32 and the third climbing ladder 33 can be fixed through 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 reset, so that the first climbing ladder 31, the second climbing ladder 32 and the third climbing ladder 33 can be folded and stored.

[0034] In this embodiment, the stepping plate 5 includes a fixed frame 51 and a connecting column 52. The connecting columns 52 are symmetrically connected on both sides of the fixed frame 51. The other end of the connecting column 52 is fixedly connected to the fixed column 34. A gripping rod 53 is provided on one side of the fixed frame 51. A plurality of anti-slip plates 54 are fixedly provided inside the fixed frame 51. The edges of the anti-slip plates 54 are provided with anti-slip patterns 541.

[0035] In this embodiment, in order to further improve the safety of climbing, the protection device 6 includes a protection belt 61 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 with T-blocks 62 through 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 arranged in the middle of the protection belt 61. Three groups of rotating rollers 14 are installed on the mounting platform 1 through a fixed frame 13. A connecting rope 15 is wound around the rotating roller 14. One end of the connecting rope 15 is fixed on 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 fixed frame 13, and 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.

[0036] It is worth noting that the protective belt 61 in the technical solution can be a belt that can be adjusted in length and fastened to the waist of a person in the prior art, and no special restrictions are made 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 stepping plate 5, the person can be protected by the cooperation of the protective belt 61, the T-block 62, and the T-slot 63 to prevent 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 protective belt 61 on the second climbing ladder 32 is first fastened to the waist, and then the protective belt 61 of the third climbing ladder 33 is loosened, so that the person can continue to climb upward, reduce the risk of falling, and improve safety.

[0037] Furthermore, before use, one end of the connecting rope 15 needs to be fixed to the connecting rings 64 on the three protection 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 can not only further improve the safety of the protection belt 61 and reduce the risk of falling, but also 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 are physically exhausted and fall into the water during the rescue process.

[0038] In this embodiment, the locking assembly 7 includes locking threaded holes 71 and locking rods 72 symmetrically arranged on both sides of the mounting platform 1. The locking threaded holes 71 are provided on one side of the mounting platform 1. The locking rods 72 are rotatably arranged on the outside of the fixing column 34 of the third climbing ladder 33. A fourth through hole 73 is provided at one end of the locking rod 72. When one end of the locking rod 72 is rotated to one side of the mounting platform 1, the fourth through hole 73 corresponds to the locking threaded hole 71. A rolling wheel 342 is also provided at the bottom of the fixing column 34 of the third climbing ladder 33. After the first climbing ladder 31, the second climbing ladder 32, the third climbing ladder 33 and the mounting platform 1 are folded, the locking rod 72 is rotated to make the fourth through hole 73 correspond to the locking threaded hole 71, and then the fastening bolts are used to fix them to prevent them from being loosened. The rolling wheels 342 are used to facilitate moving them to a designated position for storage.

[0039] When the ship climbing device of this embodiment is used, 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 protection 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; The mounting platform 1 is fixedly mounted on the hull through the mounting holes 17; The angle between the first climbing ladder 31 and the mounting platform 1 is adjusted by the first connecting assembly 2 and fixed by the locking member 23; The personnel first fastens the protective belt 61 on the third climbing ladder 33 to the waist, and then climbs upward. When climbing to the top of the third climbing ladder 33, first fastens the protective belt 61 on the second climbing ladder 32 to the waist, and then loosens the protective belt 61 of the third climbing ladder 33, and continues to climb upward. In the same way, climb to the top of the first climbing ladder 31, and then loosen the protective belt 61 of the first climbing ladder 31 after climbing onto the hull. During the climbing process, the second motor 16 controls the rotation of the rotating roller 14 to reel in the connecting rope 15, which can not only further improve the safety of the protective belt 61 and reduce the risk of falling, but also use the connecting rope 15 to provide a certain upward pulling force to reduce the resistance of the person during the climbing process; After use, the first climbing ladder 31, the second climbing ladder 32, the third climbing ladder 33 and the mounting platform 1 are folded and stored, and are fixed by the locking assembly 7 and moved to a designated position for storage.
