Technical Field
[0001] This utility model relates to the field of gangway technology, specifically an automatic folding gangway. Background Technology
[0002] A gangway is a movable ladder installed on both sides of a ship for passengers to board and disembark. It is made of wood or metal and consists of a platform, ladder frame, steps, handrails, and a hoisting device. When the ship is underway, it is hoisted up, folded up, and stored on the deck. When needed, it is lowered and suspended on the side of the ship. Gangway devices are generally used on passenger ships and other large and medium-sized vessels.
[0003] Based on the above, the inventors have discovered the following problems: Current gangways are generally designed as a single unit, which makes them difficult to fold in actual use, thus making it difficult to reduce their size. Since the size cannot be reduced, they require a large amount of space for storage, and their large size also increases transportation costs and difficulties, and may even require special transportation equipment.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic folding gangway in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide an automatic folding gangway to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] An automatic folding gangway includes a folding assembly and a guardrail assembly. The guardrail assembly is disposed outside the folding assembly. The folding assembly is used to reduce the volume of the gangway, and the guardrail assembly is used to improve the safety of the gangway. The folding assembly includes a power base, and a connecting plate is connected to the top surface of the power base. First support bars are rotatably connected to both outer sides of one end of the power base. Second support bars are connected to both outer sides of the end of the power base away from the first support bars. First connecting seats are connected to the top surfaces of a pair of first support bars, and second connecting seats are connected to the top surfaces of a pair of second support bars. The opposite ends of the first and second connecting seats are tightly fitted to the outer sides of the connecting plate, and the height of the first support bar is greater than the height of the second support bar.
[0008] Furthermore, both sides of the inner wall of the power seat are connected to rotating rods via bearings. The opposite ends of the two rotating rods pass through the power seat and are fixedly connected to a pair of first support bars respectively.
[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting two rotating rods, when the two rotating rods rotate simultaneously at the same speed and in the same direction, a pair of first support bars rotate until the first and second support bars, which were originally in an unfolded state, are in a folded state, thereby causing the first connecting seat and the second connecting seat to be in a folded state, thus reducing the volume of the gangway.
[0010] Furthermore, a dual-axis motor is installed at the center of the power base. The two output ends of the dual-axis motor are respectively fixedly connected to the ends of the two rotating rods away from the first support bar. The two output ends of the dual-axis motor have the same rotation speed and the same direction of rotation.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting up a dual-axis motor, and the two output ends of the dual-axis motor have the same speed and direction, when the dual-axis motor is started, it drives the two rotating rods to rotate.
[0012] Furthermore, the first connecting seat and the second connecting seat are internally connected to several pedals, all of which are distributed in a straight line at equal intervals, and the surfaces of the pedals and the connecting plate are provided with several anti-slip textures.
[0013] The beneficial effects of adopting the above-mentioned further solution are that by setting up several steps, it is convenient for personnel to go up and down the gangway. At the same time, the anti-slip texture on the surface of the steps and connecting plates increases the surface friction, effectively preventing personnel from slipping during walking, improving the safety of gangway use, and ensuring the stability of personnel walking on the gangway.
[0014] Furthermore, the top surface of the connecting plate is connected with I-shaped connecting strips near both ends. The guardrail assembly includes a pair of first connecting frames and a pair of second connecting frames. The pair of first connecting frames are respectively installed on both sides of the top surface of the first connecting seat, and the pair of second connecting frames are respectively installed on both sides of the top surface of the second connecting seat. The I-shaped connecting strips on the opposite sides of the first connecting frames and the second connecting frames are attached to each other near the top and bottom ends.
[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting the I-shaped strip, since the I-shaped strip is closely fitted with the first connecting frame on the first connecting seat and the second connecting frame on the second connecting seat on both sides near the upper and lower ends respectively, gaps between the first connecting frame and the second connecting frame are avoided, and the safety of the gangway during use is further improved.
[0016] Furthermore, both sides of the inner walls of the first and second connecting frames are connected to limiting seats, and a metal protective mesh is provided between the pair of limiting seats. The outer walls of both ends of the metal protective mesh are clearance-fitted with the inner walls of the limiting seats. The bottom of the inner walls of the first and second connecting frames are provided with insertion holes directly below the limiting seats. Each pair of insertion holes is provided with a rod. The top end of the rod is fixedly connected to the bottom end of the metal protective mesh. The top surfaces of the first and second connecting frames are provided with through grooves. The top end of the metal protective mesh is located inside the through grooves, and the inner wall of the through grooves is clearance-fitted with the outer wall of the metal protective mesh.
[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting a limiting seat, the limiting seat plays a limiting and guiding role for the metal protective net, ensuring the accurate position of the metal protective net during installation and use, and preventing it from shaking or shifting. Through the cooperation of the insertion rod, insertion hole, and through groove, the metal protective net can be stably installed inside the first connecting frame or the second connecting frame. When the metal protective net is pushed upward, it moves upward from the first connecting frame or the second connecting frame and is pushed out from the through groove. At this time, the insertion rod and the insertion hole separate.
[0018] Furthermore, a pair of first threaded holes are provided on both sides of the inner interior of the first connecting frame and the second connecting frame, and a second threaded hole is provided on both sides of the inner interior of the metal protective mesh. A rust-proof bolt is threaded between adjacent first threaded holes and second threaded holes.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the use of rust-proof bolts, the first threaded hole and the second threaded hole facilitates the disassembly and assembly of the metal protective net, thereby facilitating the maintenance of the metal protective net.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic folding gangway, by setting a connecting plate on the top surface of the power seat, with the outer sides of the connecting plate respectively attached to one end of the first connecting seat and the second connecting seat, forms a basic connecting surface. By setting first support bars on both sides of the bottom end of the first connecting seat and second support bars on both sides of the bottom end of the second connecting seat, the first and second connecting seats can better bear the weight of personnel and cargo when unfolded. By setting a dual-axis motor, with the two output ends of the dual-axis motor rotating at the same speed and in the same direction, when the dual-axis motor is started, it drives two rotating rods to rotate. When the two rotating rods rotate simultaneously at the same speed and in the same direction, the pair of first support bars rotate until the first and second support bars, which were originally in the unfolded state, are in the folded state, thereby making the first and second connecting seats folded, thus reducing the volume of the gangway.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5This utility model provides a technical solution: an automatic folding gangway, including a folding assembly 1 and a guardrail assembly 2. The guardrail assembly 2 is disposed outside the folding assembly 1. The folding assembly 1 is used to reduce the volume of the gangway, and the guardrail assembly 2 is used to improve the safety of the gangway. The folding assembly 1 includes a power base 11, and a connecting plate 12 is connected to the top surface of the power base 11. First support bars 15 are rotatably connected to both sides of one end of the power base 11. Second support bars 17 are connected to both sides of the end of the power base 11 away from the first support bars 15. First connecting seats 16 are connected to the top surfaces of the pair of first support bars 15, and second connecting seats 17 are connected to the top surfaces of the pair of second support bars 17. The first connecting seat 16 and the second connecting seat 18 are respectively tightly fitted to the outer sides of the connecting plate 12. The height of the first support bar 15 is greater than the height of the second support bar 17. By setting the connecting plate 12 on the top surface of the power seat 11, and the outer sides of the connecting plate 12 are respectively fitted to one end of the first connecting seat 16 and the second connecting seat 18, a basic connecting surface is formed. By setting the first support bar 15 on both sides of the bottom end of the first connecting seat 16 and the second support bar 17 on both sides of the bottom end of the second connecting seat 18, the first connecting seat 16 and the second connecting seat 18 can better bear the weight of personnel and goods when unfolded.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5This utility model provides a technical solution: Rotating rods are connected to both sides of the inner wall of the power seat 11 via bearings. The opposite ends of the two rotating rods penetrate the power seat 11 and are fixedly connected to a pair of first support bars 15. A dual-axis motor 14 is installed at the center of the power seat 11. The two output ends of the dual-axis motor 14 are fixedly connected to the ends of the two rotating rods away from the first support bars 15. The two output ends of the dual-axis motor 14 have the same rotation speed and direction. Several pedals 19 are connected inside the first connecting seat 16 and the second connecting seat 18. The pedals 19 are evenly spaced in a straight line, and the surfaces of the pedals 19 and the connecting plate 12 are provided with several anti-slip textures. By setting a dual-axis motor... The dual-axis motor 14 has two outputs with the same speed and direction. When the dual-axis motor 14 is started, it drives two rotating rods to rotate simultaneously at the same speed and in the same direction. This causes a pair of first support bars 15 to rotate until the first support bars 15 and the second support bars 17, which were originally in an unfolded state, are folded. This causes the first connecting seat 16 and the second connecting seat 18 to be folded, thereby reducing the volume of the gangway. Several steps 19 are provided to facilitate personnel going up and down the gangway. At the same time, the anti-slip texture on the surface of the steps 19 and the connecting plate 12 increases the surface friction, effectively preventing personnel from slipping during walking, improving the safety of the gangway during use, and ensuring the stability of personnel walking on the gangway.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5This utility model provides a technical solution: the top surface of the connecting plate 12 is connected with I-shaped connecting strips 13 near both ends; the guardrail assembly 2 includes a pair of first connecting frames 21 and a pair of second connecting frames; the pair of first connecting frames 21 are respectively installed on both sides of the top surface of the first connecting seat 16, and the pair of second connecting frames are respectively installed on both sides of the top surface of the second connecting seat 18; the I-shaped connecting strips 13 on the opposite sides of the first connecting frame 21 and the second connecting frame are attached to each other near the upper and lower ends; the first connecting frame 21 and the second connecting frame... Both sides of the inner wall are connected to limit seats 22. A metal protective mesh 24 is provided between a pair of limit seats 22. The outer walls of both ends of the metal protective mesh 24 are clearance-fitted with the inner walls of the limit seats 22. The bottom of the inner walls of the first connecting frame 21 and the second connecting frame are provided with insertion holes 26 located directly below the limit seats 22. Each pair of insertion holes 26 is provided with a rod 25. The top of the rod 25 is fixedly connected to the bottom of the metal protective mesh 24. The top surfaces of the first connecting frame 21 and the second connecting frame are provided with through grooves 23. The top of the metal protective mesh 24 is provided with through grooves 23. Located inside the through groove 23, the inner wall of the through groove 23 is clearance-fitted with the outer wall of the metal protective net 24. A pair of first threaded holes are opened on both sides of the inner side of the first connecting frame 21 and the second connecting frame, and a second threaded hole is opened on both sides of the inner side of the metal protective net 24. A rust-proof bolt 27 is threadedly connected between adjacent first threaded holes and second threaded holes. By setting an I-shaped strip, since the I-shaped strip is in close contact with the first connecting frame 21 on the first connecting seat 16 and the second connecting frame on the second connecting seat 18 on the sides near the upper and lower ends respectively, gaps between the first connecting frame 21 and the second connecting frame are avoided, further improving the safety of the gangway during use. The use of the rust-proof bolt 27, the first threaded hole and the second threaded hole facilitates the disassembly and assembly of the metal protective net 24, so as to facilitate the maintenance of the metal protective net 24. When the rust-proof bolt 27 is removed, the metal protective net 24 is pulled upward, so that the metal protective net 24 is taken out through the through groove 23. At this time, the metal protective net 24 is separated from the limiting seat 22, and the insertion rod 25 is separated from the insertion hole 26.
[0033] Specifically, the working principle of this automatic folding gangway is as follows: When the dual-axis motor 14 is started, it drives two rotating rods to rotate. When the two rotating rods rotate simultaneously at the same speed and in the same direction, a pair of first support bars 15 rotate until the first support bars 15 and second support bars 17, which were originally in an unfolded state, are folded. This causes the first connecting seat 16 and second connecting seat 18 to fold, thereby reducing the size of the gangway. By setting several steps 19, it is convenient for personnel to get on and off the gangway. At the same time, the anti-slip texture on the surface of the steps 19 and connecting plate 12 increases the surface friction, effectively preventing personnel from slipping during walking, improving the safety of the gangway during use, and ensuring the safety of personnel. The stability of the crew walking on the gangway is achieved through the cooperation of the anti-rust bolt 27, the first threaded hole, and the second threaded hole, which facilitates the disassembly and assembly of the metal protective net 24 for maintenance. When the anti-rust bolt 27 is removed, the metal protective net 24 is pulled upwards, allowing it to be removed through the through groove 23. At this time, the metal protective net 24 separates from the limiting seat 22, and the insertion rod 25 separates from the insertion hole 26. Then, the new metal protective net 24 is reinserted into the first connecting frame 21 or the second connecting frame through the through groove 23. At this time, the insertion rod 25 is located in the insertion hole 26. Then, the anti-rust bolt 27 is reinstalled to complete the replacement of the metal protective net 24.
