[0040] The following is combined with Figure 1 To Attachment Figure 7 And specific embodiments are used to introduce the portable gangway transfer platform provided by the present invention.

[0041] This embodiment improves the existing portable gangway 300 and provides a portable gangway transfer platform. Figure 1 As shown, when the extended structure platform 100 of the ship blocks the ship's side boarding port set on the hull outer plate 200 in the vertical direction, resulting in the path of hoisting, deploying and disassembling the portable gangway 300 being blocked by the extended structure platform 100, the path obstacle of the hoisting deployment can be eliminated by the portable gangway transfer platform, thereby ensuring that the hoisting deployment can maintain a high efficiency of disassembling and assembling the portable gangway 300, so as to build a convenient and safe passenger boarding / disembarking gangway channel.

[0042] Combination Figures 1 to 4 As shown, the portable gangway transfer platform of this embodiment is used to connect the portable gangway 300 and the ship's boarding port, and includes an extension platform 1, a first detachable connection structure 2 and a second detachable connection structure 3. Among them, the extension platform 1 is set at the gangway boarding port on the ship, and the projection of a part of the extension platform 1 on the horizontal plane is exposed outside the extension structure platform 100; the first detachable connection structure 2 is used to detachably connect a part of the extension platform 1 with the portable gangway 300; the second detachable connection structure 3 is used to detachably connect another part of the extension platform 1 with the hull deck 400 of the ship. It should be supplemented that, in this embodiment, the hull deck 400 is connected to the hull outer plate 200, and the above-mentioned gangway boarding port is provided at the intersection.

[0043] By setting the portable gangway transfer platform, the extension platform 1 can extend out of the ship's side to a certain clear space, so that the portable gangway 300 can be connected to the extension platform 1 on the outer surface of the ship without shielding, and sufficient safe space for lifting and dismantling the portable gangway 300 can be reserved for lifting and dismantling. The loading, assembly and disassembly of the portable gangway 300 are all completed on the extension platform 1 on the outer surface of the ship without shielding, thereby eliminating the obstruction of the extension structure 100 to the lifting and deployment. In addition, the second detachable connection structure 3 facilitates the disassembly and assembly of the extension platform 1 on the hull deck 400, thereby improving the disassembly and assembly efficiency of the extension platform 1, and further providing a safe, efficient and easy-to-use boarding / disembarking gangway channel for passengers and crew members on the ship.

[0044] In this embodiment, combined with Figures 2 to 4As shown, the extension platform 1 specifically includes an extension platform body 11 and a first handrail structure 12. One specific implementation of this embodiment is that first sleeves 111 are fixedly welded on both sides of the extension platform body 11, and the first handrail structure 12 includes a first railing column 121 and a first handrail 122. The first handrail 122 is fixedly installed at the head end of the first railing column 121, and the end of the first railing column 121 is limitedly inserted into the first sleeve 111. By inserting the end of the first railing column 121 into the first sleeve 111, a stable connection between the first handrail structure 12 and the extension platform body 11 is achieved, thereby ensuring the safety of people walking on the extension platform body 11.

[0045] Furthermore, in this embodiment, the first railing column 121 and the extension platform body 11 are both made of aluminum alloy material to reduce the overall structural weight of the extension platform 1, thereby facilitating the installation and removal of the extension platform 1, and having the characteristics of being easy to obtain and low in cost. In addition, the first handrail 122 is made of wood material, and the same wood material as the handrail of the gangway handrail is used, in order to maintain the style consistency of the gangway passage and make it more beautiful.

[0046] Furthermore, in this embodiment, a third pin hole is further provided on the first sleeve 111, and a fourth pin hole is provided on the first railing post 121, and the third pin shaft is sequentially inserted into the third pin hole and the fourth pin hole, so that the first sleeve 111 and the first railing post 121 can be stably connected, preventing the first handrail structure 12 from being disengaged, and maintaining the safety and stability of the extension platform 1. Of course, in other embodiments, the first sleeve 111 and the first railing post 121 can also be fixed by other detachable connection means, such as threaded connection, snap connection, clamp, etc., and the present application is not limited to this.

[0047] Optionally, in this embodiment, refer to Figure 4 As shown, a patterned plate 112 is provided on the upper surface of the extended platform body 11. The patterned plate 112 can increase the friction between the walking personnel and the extended platform body 11, thereby preventing the personnel from slipping when passing through, thereby further improving the safety of the portable gangway transfer platform.

[0048] Optionally, in this embodiment, refer to Figure 3 As shown, a avoidance groove 113 is also provided at the bottom of the extended platform body 11. The avoidance groove 113 is arranged relative to the part of the hull outer plate 200 protruding from the hull deck 400 in the vertical direction, thereby ensuring that the extended platform body 11 is in a flat state after being fixed on the hull deck 400, facilitating the passage of personnel.

[0049] Optionally, in this embodiment, continue to refer to Figure 3As shown, a diagonal bracing mechanism 13 is also provided at the bottom of the extension platform body 11, and the diagonal bracing mechanism 13 can provide support stability for the extension platform body 11. Specifically, in this embodiment, one end of the diagonal bracing mechanism 13 is hingedly connected to the extension platform 1, and the other end of the diagonal bracing mechanism 13 can rotate with the hinge point, so that when the extension platform body 11 lies flat on the hull deck 400, the other end of the diagonal bracing mechanism 13 can abut against the hull outer plate 200, so that the weight load of the portion of the extension platform 1 that is not overlapped on the hull deck 400 can be borne by the diagonal bracing mechanism 13, thereby ensuring the stability and safety of the extension platform 1.

[0050] The first detachable connection structure 2 specifically includes a hanging shaft 21 and a hook 22. One specific implementation of this embodiment is to refer to Figure 4 As shown, a portion of the platform body 11 extending outward is provided with a plurality of hanging shafts 21 at the end facing the outer side of the ship, for example Figure 4 There are three hanging shafts 21 shown in the figure, and the three hanging shafts 21 are fixedly arranged on the same straight line. A hook 22 is fixedly arranged on the portable gangway 300. When deploying the portable gangway 300, refer to Figure 1 As shown, the lower end of the portable gangway 300 falls on the ground of the dock 500, and the upper end is hooked on three hanging shafts 21 through a plurality of hooks 22, thereby quickly and conveniently completing the connection between the portable gangway 300 and the extension platform 1.

[0051] Of course, it is understandable that in some other parallel embodiments, a part of the extension platform body 11 may be provided with a plurality of hooks 22 at the end facing the outside of the ship, and a plurality of hanging shafts 21 may be fixedly provided on the portable gangway 300. By mutually hanging the plurality of hanging shafts 21 on the portable gangway 300 with the plurality of hooks 22 on the extension platform body 11, the effect of detachably connecting the extension platform 1 and the portable gangway 300 can also be achieved. Therefore, those skilled in the art can arbitrarily select the above two embodiments for design and manufacture according to actual working conditions, and the present invention is not limited thereto.

[0052] Furthermore, in order to improve the connection stability between the portable gangway 300 and the extension platform 1, in this embodiment, a locking mechanism is also provided on the hook 22, through which the hook 22 and the hanging shaft 21 can be detachably fixedly connected, thereby not only ensuring the connection stability between the portable gangway 300 and the extension platform 1, but also removing the locking mechanism and then dismantling the connection between the hook 22 and the hanging shaft 21, so as to achieve the purpose that the portable gangway transfer platform can be stored separately and leave space for passengers to move around. It should be noted that this embodiment does not limit the type of use of the locking mechanism, as long as the hook 22 and the hanging shaft 21 can be detachably fixedly connected, it is within the scope of protection of this application.

[0053] Optionally, in this embodiment, another part of the extension platform 1 is also provided with a hinge connection mechanism 14, which is installed on the extension platform body 11. The hinge connection mechanism 14 is connected to the hull deck 400 through a second detachable connection structure 3, and the extension platform body 11 is hingedly connected to the hull deck 400.

[0054] For example, Figure 5 As shown, when the extension platform body 11 is installed on the hull deck 400, the extension platform body 11 is first deployed through the preset fixed hanging point 600 using the hand chain hoist 700 device, and the extension platform body 11 is first placed on the hull deck 400 below the hanging point (refer to Figure 5 11a, which is the state of the extension platform body 11 at this time), the extension platform body 11 is lifted vertically to a suitable height by the hand chain hoist 700, and then the hinge connection mechanism 14 is aligned with the preset fixed point on the hull deck 400, and then the extension platform 1 and the hull deck 400 are fixedly connected by the second detachable connection structure 3. Subsequently, the foldable diagonal bracing mechanism 13 is opened. After the diagonal bracing mechanism 13 is opened, the extension platform 1 is turned down and laid flat by the hand chain hoist 700 (refer to Figure 5 As shown by the flip arrow X in the figure), the other end of the diagonal bracing mechanism 13 can abut against the reserved position of the hull outer plate 200 (reference Figure 5 11b shown in the figure is the state of the extension platform body 11 at this time). Finally, the hand chain hoist 700 is released to complete the deployment of the extension platform 1. Through the setting of the above-mentioned hinge connection mechanism 14, the installation steps of the extension platform 1 can be simplified, the deployment efficiency is improved, and the obstruction of the extension structure platform 100 is effectively avoided. It can be understood that the operation steps of removing the extension platform 1 from the hull deck 400 by the hand chain hoist 700 are opposite to the operation steps of installing the extension platform 1, and the principle is the same, so this embodiment will not be repeated here.

[0055] It should be noted that, in this embodiment, the extension platform 1 can be slowly flipped downward to a flat state by connecting the suspension rope 800 installed on the fixed suspension point 600 to a hanging shaft 21, thereby ensuring that the extension platform 1 can be stably lowered to a predetermined position by controlling the flipping speed of the extension platform 1, thereby reducing damage or safety hazards that may be caused by descending too quickly.

[0056] Specifically, in this embodiment, the second detachable connecting structure 3 includes a first pin hole and a first latch. One specific implementation of this embodiment is that a first pin hole is opened on the hinge connection mechanism 14, and a first latch is protruding upward on the hull deck 400. By inserting the first latch into the first pin hole, the extension platform 1 can be locked on the hull deck 400, thereby effectively simplifying the way of fixing the extension platform 1 on the hull deck 400.

[0057] Preferably, in this embodiment, two hinge connection mechanisms 14 are arranged at intervals on the same side of the extension platform body 11, and a first pin hole is opened on one side of each hinge connection mechanism 14, and two first latches are correspondingly arranged on the hull deck 400, and the first latches correspond to the first pin holes one by one, so as to further improve the connection stability between the extension platform 1 and the hull deck 400. Of course, it can be understood that in other embodiments, the first latch can also be arranged on one side of the hinge connection mechanism 14, and the first pin hole can be opened on the hull deck 400. When the extension platform 1 is lifted to a suitable height by the hand chain hoist 700, the first latch on the hinge connection mechanism 14 can be aligned and inserted into the first pin hole, so that the purpose of locking the extension platform 1 on the hull deck 400 can be achieved. Therefore, the above two embodiments are within the scope of protection of the present invention.

[0058] Optionally, combined Figure 3 , Figure 6 and Figure 7 As shown, the portable gangway transfer platform provided in this embodiment also includes a transition platform 4 and a third detachable connection structure 5. Among them, one end of the transition platform 4 is connected to the other part of the extension platform 1 through the third detachable connection structure 5, and the other end of the transition platform 4 is overlapped on the hull deck 400, so that the transition platform 4 is inclined. Through the action of the transition platform 4, a smooth inclined transition area can be formed from the extension platform 1 to the hull deck 400, which helps to reduce the height difference between the hull deck 400 and the extension platform 1, ensuring that people can pass safely and smoothly, reducing the tripping and slide hazards caused by the right-angle slope, and improving the safety of the entire portable gangway transfer platform and the comfort of people.

[0059] Specifically, combined Figure 4 , Figure 7As shown, the third detachable connection structure 5 includes a second pin hole 51 and a second latch 52. One specific implementation of this embodiment is that the second pin hole 51 is provided on the side of the extension platform body 11 close to the transition platform 4, and the second latch 52 is provided at the bottom of the side of the transition platform 4 close to the extension platform body 11. The number of the second pin hole 51 and the second latch 52 is not limited. After the transition platform 4 is overlapped on the extension platform body 11, the second latch 52 is limitedly inserted into the second pin hole 51, thereby completing the locking and fixing of the transition platform 4 and the extension platform 1. When disassembling, the transition platform 4 is lifted, and the second latch 52 is pulled out from the second pin hole 51, and the removal of the transition platform 4 is completed. The disassembly and assembly operation of the above-mentioned transition platform 4 is simple and convenient, and easy to implement, thereby further improving the construction convenience of the entire portable gangway transfer platform. At the same time, the second latch 52 can effectively limit the movement of the transition platform 4 in the horizontal direction, thereby ensuring the tightness of the connection between the transition platform 4 and the extension platform 1, and preventing the generation of gaps.

[0060] Of course, it is understandable that in other embodiments, a second pin 52 may be provided on the extension platform body 11, and a second pin hole 51 may be provided on the transition platform 4. In this way, when the transition platform 4 is overlapped on the extension platform body 11, the transition platform 4 and the extension platform 1 may be locked and fixed by inserting the second pin 52 into the second pin hole 51. Therefore, those skilled in the art may select any implementation method according to actual working conditions, and the present application is not limited thereto.

[0061] More specifically, the transition platform 4 provided in this embodiment specifically includes a first plate body 41 and a second plate body 42. The first plate body 41 is attached to and fixedly connected to the second plate body 42. The side of the first plate body 41 away from the second plate body 42 is provided with an anti-slip structure 411 to improve the safety of people passing through the transition platform 4; the side of the second plate body 42 away from the first plate body 41 is provided with longitudinal and transverse reinforcing frames to form reinforcing ribs 421, so that the structural strength of the transition platform 4 placed in an inclined state can be increased to avoid bending and deformation of the transition platform 4.

[0062] Optionally, in this embodiment, the transition platform 4 also includes a second handrail structure 43, which is arranged on the second plate body 42 and connected to the first handrail structure 12, so as to enhance the safety of passage for personnel when passing through the transition platform 4 and extending out of the platform 1, and further reduce the risk of slipping and falling.

[0063] One specific implementation of this embodiment is that the second sleeve 422 is fixedly welded on both sides of the second plate body 42, the second handrail structure 43 includes a second railing column 431 and a second handrail 432, the end of the second railing column 431 is limitedly inserted into the second sleeve 422, and the second handrail structure 43 is fixedly connected to the second plate body 42 by inserting the second railing column 431 into the second sleeve 422. In addition, the second handrail 432 is fixedly installed at the head end of the second railing column 431, so that the second handrail structure 43 is stably installed on the second plate body 42.

[0064] Furthermore, in this embodiment, the second railing column 431, the first plate body 41 and the second plate body 42 are all made of aluminum alloy material to reduce the overall structural weight of the transition platform 4, facilitate the installation and removal of the transition platform 4, and have the characteristics of easy acquisition and low cost. In addition, the second handrail 432 is made of wood material, and is the same wood material as the handrail of the gangway handrail and the first handrail 122. The purpose of this setting is to maintain the style consistency and good aesthetics of the gangway passage.

[0065] Furthermore, in this embodiment, a fourth pin hole is further provided on the second sleeve 422, a fifth pin hole is provided on the second railing column 431, and a fourth pin shaft is sequentially inserted into the fourth pin hole and the fifth pin hole, so as to fix the second sleeve 422 and the second railing column 431 through the first pin shaft, thereby preventing the second handrail structure 43 from being disengaged and maintaining the safety and stability of the transition platform 4. Of course, in some other parallel embodiments, the second sleeve 422 and the second railing column 431 can also be fixed by other detachable connection means, such as threaded connection, snap connection, clamp, etc., which is not limited in this application.

[0066] Optionally, in this embodiment, the transition platform 4 further includes a third handrail structure, which includes at least a third railing column 441, and a third sleeve 412 is protrudingly provided on the first plate body 41, and a plug hole 423 is provided on the second plate body 42, and the plug hole 423 corresponds to and is connected to the third sleeve 412. In this embodiment, the third sleeve 412 is located in the middle of the first plate body 41, that is, the third sleeve 412 can divide the single channel passing through the transition platform 4 into a double channel, so that when the portable gangway 300 is a double channel, by inserting the third railing column 441 into the third sleeve 412, the transition platform 4 can be divided from a single channel to a double channel, so as to cooperate with the double-channel portable gangway 300, thereby ensuring smooth passage and reducing channel congestion. In addition, the portable gangway transfer platform provided in the present embodiment has detachable connections between the extending platform body 11 and the first plate body 41, between the extending platform body 11 and the first handrail structure 12, between the second plate body 42 and the second handrail structure 43, and between the first plate body 41 and the third handrail structure. This greatly facilitates the installation, removal and storage of the portable gangway transfer platform, thereby being able to well meet the requirements for efficient deployment of the portable gangway 300.

[0067] It should be supplemented that, in some other parallel embodiments, the third handrail structure may further include a third handrail, which is disposed at the head end of the third railing column 441 to facilitate personnel to walk and hold steadily on the transition platform 4.
