Technical Field

[0001] The utility model relates to the technical field of folding gangways, in particular to a portable gangway with a folding function. Background Technique

[0002] For various ships, the gangway provides a safe and reliable passage for getting on and off the ship. Whether it is for crew members to board and leave the ship during daily work or for passengers to get on and off the ship, the gangway can ensure a smooth transition between different heights. When loading and unloading goods at the dock, the gangway can serve as a bridge connecting the ship and the dock, facilitating the handling of goods by the staff.

[0003] A portable gangway is light in weight, and one person can easily carry and operate it, which is very important in many cases. For example, on small ships with a limited number of crew members, they need to be able to independently complete the arrangement and retraction of the gangway. Compared with heavy gangways, the handling and installation process of portable gangways do not require excessive physical strength.

[0004] At present, most of the gangways on the market can be folded through joint rotating shafts to change the length of the gangway and reduce the storage space. However, most of the gangway surfaces cannot be folded and reduced to reduce the floor area, resulting in the inability to store the gangway well in a limited narrow space. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a portable gangway with a folding function, aiming to improve the problem that most of the gangway surfaces in the existing technology cannot be folded and reduced to reduce the floor area, resulting in the inability to store the gangway well in a limited narrow space.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A portable gangway with a folding function, including a fixed plate. Grooves I are opened at the tops of both fixed plates. Rotating shafts I are fixedly connected to the bottoms of both fixed plates. Rotating plates are rotatably connected to the outer walls of both rotating shafts I.

[0008] The supporting mechanism includes a first rotating rod. Both of the two first rotating rods are fixedly connected to the bottom of the front end of the corresponding fixing plate. The bottom of each of the two first rotating rods is rotatably connected to a supporting rod. The bottom of the front end of each of the two fixing plates is fixedly connected to a second rotating rod. The bottom of each of the two second rotating rods is rotatably connected to a second fixing rod. The bottom of the second fixing rod is slidably connected to a moving rod. A plurality of reserved grooves are equidistantly formed on the opposite sides of the two moving rods. A second limiting bolt is rotatably connected to the opposite side of each of the two second fixing rods. The bottom ends of the corresponding moving rods and supporting rods are fixedly connected to the same bottom plate.

[0009] As a further description of the above technical solution:

[0010] Grooves are formed at the bottom of each of the two rotating plates. A second rotating shaft is fixedly connected to the inside of each of the two grooves. A limiting plate is fixedly connected to one side of each of the two second rotating shafts. A first limiting bolt is rotatably connected to one side of each of the two limiting plates.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a portable gangway with a folding function, including a fixing plate 1. Grooves 3 are opened at the tops of both fixing plates 1. Rotating shafts 1 are fixedly connected to the bottoms of both fixing plates 1. Rotating plates 5 are rotatably connected to the outer walls of both rotating shafts 1. Corresponding moving plates 6 and fixing rods 7 are fixedly connected to the adjacent sides of both fixing plates 1 and the rotating plates 5 at equal intervals respectively. Circular grooves 8 are opened on the right sides of the tops of multiple moving plates 6. Springs 9 are fixedly connected to one sides of the interiors of multiple circular grooves 8. Limiters 10 are fixedly connected to the tops of multiple springs 9. Sliding grooves 11 are opened on the left sides of multiple fixing rods 7. Limiting holes 12 are opened on the left tops of multiple fixing rods 7. Multiple moving plates 6 slide inside the corresponding sliding grooves 11 respectively. Support mechanisms 2 are arranged at the bottoms of both fixing plates 1. The support mechanisms 2 are used to support the fixing plates 1. Grooves 13 are opened at the bottoms of both rotating plates 5. Rotating shafts 14 are fixedly connected to the interiors of both grooves 13. Limiting plates 15 are fixedly connected to one sides of both rotating shafts 14. Limiting bolts 1 are rotatably connected to one sides of both limiting plates 15. Fixing holes 17 are opened at the tops of both fixing plates 1. Multiple limiters 10 slide inside the corresponding limiting holes 12 respectively. The sizes of the limiters 10 and the limiting holes 12 are the same.

[0033] Specifically, first fix the reserved plate 20 at a predetermined position, then insert the rotating plate 19 into the interior of the reserved plate 20, and then fix it with the fixing bolt 21. Pull the rotating plate 5 to make the rotating shaft 4 rotate, and the rotating plate 5 also rotates to a position parallel to the groove 3. In this way, the moving plate 6 and the fixing rod 7 between the two rotating plates 5 will also rotate accordingly. Then pull the fixing plate 1 to the left to make the moving plate 6 move to the left. When the limiter 10 touches the limiting hole 12, the spring 9 will release pressure and push the limiter 10 into the limiting hole 12, so that the limiter 10 can fix the moving plate 6 and the fixing rod 7. When the gangway needs to be retracted, it is necessary to rotate the rotating plate 5 to make it rotate into the groove 3. The rotating plate 5 drives the fixing rod 7 to rotate upward. At this time, the top of the fixing rod 7 will push up the limiter 10, and the spring 9 will retract. Then push the fixing plate 1 to make the moving plate 6 slide into the sliding groove 11, so that the area of the pedal becomes smaller.

[0034] Reference Figure 4 and Figure 5 The supporting mechanism 2 includes a rotating rod 201, two rotating rods 201 are fixedly connected to the front bottom of the corresponding fixed plate 1, the bottom of the two rotating rods 201 are rotatably connected to the support rod 202, the front bottom of the two fixed plates 1 are fixedly connected to the rotating rod 203, the bottom of the two rotating rods 203 are rotatably connected to the fixed rod 204, the bottom of the fixed rod 204 is slidably connected to the moving rod 205, the two moving rods 205 have multiple reserved grooves 206 equidistantly provided on the side away from each other, the two fixed rods 204 have multiple rotatably connected on the side away from each other, and the multiple moving rods 205 and the bottom of the corresponding support rod 202 are fixedly connected to the same bottom plate 208;

[0035] Specifically, when the gangway ladder is to be used, the second limit bolt 207 must be rotated first, so that it no longer limits the moving rod 205, and then the moving rod 205 is pulled out of the fixed rod 204, so that the fixed rod 204 becomes longer, and then the limit bolt 207 is passed through the fixed rod 204 and inserted into the reserved groove, and then the fixed rod 204 and the support rod 202 are rotated, so that the first rotating rod 201 and the second rotating rod 203 will also rotate. Finally, the bottom plate 208 can be close to the ground and stably support the gangway ladder.

[0036] Reference Figure 2 The tops of the two fixed plates 1 are fixedly connected with the rotating shaft 3 18, one side of the two rotating shafts 3 18 is rotatably connected with the rotating plate 19, the outer walls of the two rotating plates 19 are slidably connected with the reserved plates 20, and the tops of the two reserved plates 20 are rotatably connected with the fixing bolts 21;

[0037] Specifically, the rotating shaft 3 18 and the rotating plate 19 are convenient for rotating at different angles according to different angles, and the rotating plate 19 is fixed. The reserved plate 20 and the fixing bolts 21 are convenient for fixing the rotating plate 19.

[0038] Reference Figure 2 and Figure 4 The bottoms of the two bottom plates 208 are fixedly connected with soft pads 22, and the bottoms of the two soft pads 22 are fixedly connected with multiple rubber plates 23 at equal distances. The bottoms of the multiple movable plates 6 and the fixed rod 7 are fixedly connected with support plates 24, and one side of the multiple support plates 24 is respectively fixedly connected to one side of the corresponding movable plate 6 and the fixed rod 7;

[0039] Specifically, the soft pad 22 and the rubber pad 23 can increase the friction of the bottom plate 208 to make the support more stable, and the support plate 24 can reinforce the movable plate 6 and the fixed rod 7 to make them more stable.

[0040] Working principle: When using a portable gangway with a folding function, the reserved plate 20 needs to be fixed at a predetermined position first. At this time, the rotating plate 19 at the top of the fixed plate 1 is inserted into the corresponding reserved plate 20, and at the same time, the fixing bolt 21 is rotated to fix it. Then, the rotating plate 5 is pulled to make the first rotating shaft 4 rotate, and at the same time, the rotating plate 5 rotates to form a right angle with the first groove 3. At this time, the moving plate 6 and the first fixed rod 7 between the two rotating plates 5 rotate accordingly. At the same time, the two fixed plates 1 on both sides are pulled to move the moving plate 6 to the left. When the stopper 10 moves to the left and encounters the limit hole 12, the spring 9 releases pressure to push the stopper 10 into the limit hole 12, so that the stopper 10 limits and fixes the moving plate 6 and the first fixed rod 7. When the gangway needs to be folded, the rotating plate 5 is rotated at this time to rotate the rotating plate 5 into the first groove 3. At the same time, the rotating plate 5 drives the first fixed rod 7 to rotate upward. At this time, the top of the rotated first fixed rod 7 will squeeze the stopper 10 at the top of the first fixed rod 7 between the fixed plates 1, so that the stopper 10 squeezes the spring 9 to contract. At the same time, the fixed plate 1 is pushed to push the moving plate 6 into the sliding groove 11, reducing the pedal area;

[0041] And when the gangway needs to be supported, the support mechanism 2 can be adjusted as needed. At this time, the limit on the moving rod 205 is cancelled by rotating the second limit bolt 207. At the same time, the moving rod 205 is pulled out of the second fixed rod 204 to extend the length of the second fixed rod 204. At this time, the second limit bolt 207 passes through the second fixed rod 204 and is inserted into the corresponding reserved groove 205. At the same time, the second fixed rod 204 and the support rod 202 are rotated. At this time, the first rotating rod 201 and the second rotating rod 203 rotate, so that the bottom plate 208 fits with the ground for support.

[0042] 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 described in the foregoing embodiments, or perform equivalent replacements for 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.
