An adjusting mechanism 2 is provided on the top of the connecting plate 3, and the adjusting mechanism 2 is used to facilitate height adjustment according to people of different heights. A plurality of pedals 12 are equidistantly fixedly connected to the adjacent sides of the two connecting plates 3, and the tops of the plurality of pedals 12 are all provided with anti-slip grooves 13;

[0034] Specifically, suction cup 8 is first tightly attached to a designated position on the hull, ensuring it is firmly fixed to the hull surface. Then, electric push rod 5 drives push plate 6 to move backward. As push plate 6 moves backward, support rod 10 also drives piston 11 backward accordingly. During this process, piston 11 extracts air from suction cup 8, creating a vacuum inside. This vacuum effectively prevents the gangway ladder from being disturbed by external factors during use, thereby avoiding the problem of gangway ladder shaking. At the same time, this structural design does not damage the sealing and structural strength of the hull, ensuring the integrity and safety of the hull.

[0035] Reference Figure 1 、 Figure 4 and Figure 5The adjusting mechanism 2 includes a hollow column 201, a connecting rod 208 and a U-shaped rod 209. The multiple hollow columns 201 are fixedly connected to the left and right sides of the corresponding top of the connecting plate 3. An open groove 202 is opened on one side of the hollow column 201. The interior of the hollow column 201 is slidably connected to a movable column 203. The outer wall of the left hollow column 201 is rotatably connected to a rotating rod 204. One end of the two rotating rods 204 passes through the corresponding hollow column 201 and is fixedly connected to an active bevel gear 205. The inner bottom end of the left hollow column 201 is rotatably connected to a screw rod 206. The two screw rods The outer walls of 206 are respectively threadedly connected to the corresponding movable columns 203, one side of the multiple movable columns 203 is respectively fixedly connected to the left and right ends of the corresponding connecting rods 208, the tops of the multiple movable columns 203 are respectively fixedly connected to the bottom ends of the corresponding U-shaped rods 209, the middle and lower parts of the outer sides of the multiple screw rods 206 are fixedly connected to the driven bevel gears 207, and the two driven bevel gears 207 are respectively meshed with the corresponding active bevel gears 205. The adjustment mechanism 2 also includes an anti-slip sleeve 210, and the multiple anti-slip sleeves 210 are respectively and equidistantly fixedly connected to the outer walls of the corresponding U-shaped rods 209;

[0036] Specifically, when the rotating rod 204 is rotated, the active bevel gear 205 located on the outside of the rotating rod 204 will also rotate accordingly. The active bevel gear 205 is tightly meshed with the driven bevel gear 207, so the driven bevel gear 207 will also rotate accordingly. This rotation mechanism enables the screw rod 206 to rotate smoothly. At the same time, the movable column 203 on the outside of the screw rod 206 will move upward along the direction of the slide groove 212 inside the slide groove 212, and the connecting rod 208 between the movable columns 203 will also move upward synchronously with the rise of the movable columns 203, which can further improve its safety during use.

[0037] Reference Figure 4 、 Figure 5 and Figure 6 The adjustment mechanism 2 also includes a slider 211. The multiple sliders 211 are fixedly connected to the front and rear sides of the corresponding movable column 203. The front and rear sides of the left hollow column 201 are provided with a slide groove 212. The multiple sliders 211 are respectively slidably connected to the corresponding slide groove 212. The sizes of the multiple sliders 211 match the internal sizes of the corresponding slide groove 212.

[0038] Specifically, the sliding groove 212 can limit the moving track of the movable column 203 so that it can move more smoothly.

[0039] Reference Figure 1 , the front and rear sides of the top of the base 1 are both threadedly connected with fixing bolts 14, and the bottom ends of the two fixing bolts 14 pass through the base 1;

[0040] Specifically, the base 1 can be conveniently fixed by the fixing bolts 14, thereby conveniently fixing the gangway.

[0041] Reference Figure 2 and Figure 3 , the multiple electric push rods 5 are electrically connected to the external remote control, and the sizes of the multiple pistons 11 are matched with the internal sizes of the corresponding connecting tubes 9;

[0042] Specifically, the operation of the electric push rod 5 can be controlled by an external remote controller. The model of the electric push rod 5 is ZLD-TG-150mm.

[0043] Working Principle: Before using the gangway ladder, first install the base 1 on the hull with the fixing bolts 14 to fix the gangway ladder. When using, just lower the gangway ladder. After the gangway ladder is lowered from the hull, the suction cup 8 is first sucked onto the hull. Then, the electric push rod 5 can drive the push plate 6 to move backward. The support rod 10 will then drive the piston 11 to move backward to extract the air in the suction cup 8, making it a vacuum state. This can prevent the gangway ladder from shaking due to external factors during use. This structure is not easy to damage the sealing and structural strength of the hull.

[0044] When using the gangway ladder, the user can rotate the rotating rod 204 according to his or her height, and the active bevel gear 205 outside the rotating rod 204 will rotate accordingly, and the driven bevel gear 207 engaged with it will also rotate accordingly, thereby driving the screw rod 206 to rotate. At the same time, the movable column 203 outside the screw rod 206 will move upward inside the slide groove 212, and the connecting rod 208 between the movable columns 203 will also move upward at the same time, thereby further improving the safety of the gangway ladder.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
