[0034] Specifically, the gangway is placed at the edge of the hull. When in use, first start the servo motor 3 to drive the first gear 4 to rotate. Through the meshing of the first gear 4 and the second gear 5, the clamping block cylinder 6 can be driven to rotate, so that the ladder side plate 7 rotates, making its bottom contact the shore. Subsequently, by starting the contraction assembly, by starting the hydraulic rod 12, the tops of the first rotating plate 8 and the second rotating plate 9 can be driven to move in the chute 11 above the ladder side plate 7, so that the two ladder side plates 7 move away from each other. At the same time, the first pedal 13 will move out of the inner wall of the hollow plate 14. When the first pedal 13 completely moves out of the hollow plate 14, it will drive the hollow plate 14 to continue moving until both ends of the second pedal 15 completely move to the outermost side of the hollow plate 14, thus the gangway is unfolded.

The upper and lower sides of the inner wall of the right ladder side plate 7 are both rotatably connected to the rotating plate 29. The top of the rotating plate 29 is fixedly connected with a rotating column 10. The top of the outer wall of the rotating column 10 passes through the rotating plate 8. The upper and lower sides of the inner wall of the ladder side plate 7 are provided with a sliding groove 11. The top of the rotating plate 8 and the rotating plate 29 are respectively slidably connected to the corresponding sliding groove 11. The top of the top rotating plate 8 and the front bottom of the rotating plate 29 are both rotatably connected with a hydraulic rod 12. One end of the two hydraulic rods 12 is fixedly connected to the top rotating plate 8 and the rotating plate 29, respectively. A lamp post 20 is fixedly connected to the right side of the top of the fixed plate 1, and a street lamp 21 is fixedly connected to the front bottom of the lamp post 20;
[0038] Specifically, by starting the hydraulic rod 12, the top of the turn plate 1 8 and the turn plate 2 9 can be pushed toward the top of the ladder side plate 7, so that the ladder side plates 7 on both sides move toward the middle and merge. The street lamp 21 can provide lighting to prevent the road from being unclear when boarding the ship at night.
[0039] Reference Figure 1 , Figure 2 and Figure 3 , a plurality of anti-slip blocks 22 are fixedly connected to the top of the L-shaped plate 18, a warning sign 23 is fixedly connected to the right side of the right buffer block 206, a buffer pad 24 is fixedly connected to the bottom of the buffer block 206, a plurality of anti-slip grooves 25 are provided at the bottom of the buffer pad 24, a notice board 26 is fixedly connected to the right side of the right ladder side plate 7, a plurality of colored lights 27 are fixedly connected to the right side of the notice board 26, and a plurality of arc grooves 28 are provided on the adjacent sides of the two ladder side plates 7, and the arc grooves 28 are respectively slidably connected to the rear sides of the corresponding pedals 13;
[0040] Specifically, the anti-slip block 22 can improve the anti-slip ability of the L-shaped plate 18, the warning sign 23 can remind people to pay attention to safety, the buffer pad 24 can improve the impact of the buffer block 206 with the shore, and the anti-slip groove 25 can improve the anti-slip ability of the buffer pad 24, the notice board 26 can increase the aesthetics, the colorful lights 27 can emit flashing light at night, and the arc groove 28 can facilitate the rotation of the pedal 13.
[0041] Working principle: Before using this device, first, the gangway device is placed at the edge of the hull. When in use, the servo motor 3 is activated first, and then the first gear 4 is driven to rotate. The meshing transmission between the first gear 4 and the second gear 5 causes the clamping block cylinder 6 to rotate accordingly, and then drives the ladder side plate 7 to rotate, so that the bottom of the ladder contacts the shore. Subsequently, the contraction assembly is started, and the telescopic movement of the hydraulic rod 12 drives the first rotating plate 8 and the second rotating plate 9 to move in the chute 11 above the ladder side plate 7, realizing the separation movement of the two ladder side plates 7. At the same time, the first pedal 13 slides out from the inner wall of the hollow plate 14. When the outermost side of the first pedal 13 moves out of the hollow plate 14, the hollow plate 14 will continue to move until both ends of the second pedal 15 completely move to the outermost side of the hollow plate 14, thus completing the deployment of the gangway. During the rotation process, the fixing effect between the second pedal 15 and the fixing strip 16 ensures that the first pedal 13, the hollow plate 14, and the second pedal 15 remain in a horizontal state, and the other first pedals 13, the hollow plate 14, and the second pedal 15 are synchronously maintained in a horizontal state through the rotating strip 17;
[0042] And through the protection mechanism 2, the arrangement of the drain holes 201 ensures that the surface of the second pedal 15 will not accumulate water. The introduction of the conical anti-slip holes 202 enhances the anti-slip performance of the first pedal 13, and the anti-slip strips 203 increase the friction coefficient of the hollow plate 14. The combined use of the protection rods 204 and the safety ropes 205 guarantees the safety of people when using the gangway and prevents accidental falls. The function of the buffer block 206 is to reduce the impact force when the ladder side plate 7 contacts the shore, thus avoiding potential damage.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
