[0021] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0022] In Embodiment 1 of the marine transfer device of the present invention: like Figure 4 As shown, the marine transition device in this embodiment includes three parts: an upward and downward inclined ramp assembly and an intermediate transition assembly with a certain height and arranged horizontally. The assembly of these three components can span the door frame 5, thereby enabling the flatbed truck to pass through the door frame 5.

[0023] Specifically, such as Figure 1 As shown, the ramp assembly includes two parallel, spaced-apart ramp members connected by a first crossbeam 15. The length of the first crossbeam 15 is determined according to the specifications of the flatbed truck used, allowing the wheels on both sides of the flatbed truck to pass through. The first crossbeam 15 and the ramp members on both sides are welded together. Of course, in other embodiments, the width of the two ramp members can be increased, and the first crossbeam can be omitted, directly connecting the two ramp members. In this case, the weight of the ramp assembly will naturally increase.

[0024] The structure is described using a single ramp component as an example. The ramp component includes a first ramp plate 11 and a second ramp plate 12 arranged at an angle. The first ramp plate 11 is positioned close to the ground, and the bottom end of the second ramp plate 12 is located at the top end of the second ramp plate 12, with their ends aligned. Support structures are provided at the bottom of the first ramp plate 11 and the second ramp plate 12 to support the ramp plates. Specifically, the support structure below the first ramp plate 11 is a solid triangular plate, and horizontally arranged support pads are provided on the side of the triangular plate that is close to the ground, thereby increasing the contact area with the ground. Below the second ramp plate 12, a first reinforcing plate 13 is arranged parallel to the surface of the second ramp plate 12. The first reinforcing plate 13 is vertically arranged and has multiple arrayed weight-reducing holes 32. A first support leg 14 is also provided on the first reinforcing plate 13. The first support leg 14 is a plate structure and is integrally formed with the first reinforcing plate 13. A support pad is also provided at the bottom of the first support leg 14. A rubber pad 31 is also provided at the bottom of the support pad to protect the paint on the ship and prevent it from being scratched during use.

[0025] The door frame 5 on the ship may have a double door frame 5 style, in which case a larger horizontal span is required. In this embodiment, an intermediate transition component is also provided to increase the horizontal span. Specifically, such as Figure 2 As shown, an intermediate transition assembly is used to connect the two ramp assemblies. The intermediate transition assembly includes two parallel, spaced-apart intermediate transition members connected and fixed by a second crossbeam 24. The second crossbeam 24 has the same length as the first crossbeam 15, ensuring that each intermediate transition member corresponds to its respective ramp member. The intermediate transition member includes a horizontally placed horizontal panel 21 and a second reinforcing plate 22 located below the horizontal panel 21. A second support leg 23 is located below the second reinforcing plate 22. The second reinforcing plate 22 has weight-reducing holes 32 for weight reduction, and the second support leg 23 facilitates lifting the intermediate transition plate above the door frame 5.

[0026] To ensure a stable connection between the ramp component and the intermediate transition component during use, a locking structure is also provided between them. Specifically, such as... Figure 3As shown, the locking structure includes a hanging ring 42 on one component and a hook 41 on the other component. In this embodiment, both the hanging ring 42 and the hook 41 are fixedly welded to the components. One ramp component has a hanging ring 42 fixedly welded to it, and the other ramp component has a hook 41. The intermediate transition component has a hanging ring 42 at one end and a hook 41 at the other end. The hanging ring 42 and hook 41 facilitate the connection of these components into a single unit. To better limit the movement of the components, each component has two hanging rings 42 or hooks 41. This arrangement allows for a locking effect towards the center after the fixed connection is completed, enhancing the limiting effect. Of course, in other embodiments, hooks 41 can be provided on both ramp components, and hanging rings 42 can be provided at both ends of the intermediate transition component. In this case, the ramp component can only connect with the intermediate transition component, and cannot directly connect with the two ramp components.

[0027] In order to cross the door frame 5, a certain degree of clearance from the door frame 5 is required. In this embodiment, the distance between the first support leg 14 and the edge of the ramp component is greater than half the width of the door frame 5, and the distance between the second support leg 23 and the edge of the middle transition component is greater than half the width of the door frame 5. Thus, after installation, a space to accommodate the door frame 5 can be formed between the first support leg 14 and the second support leg 23. Two sets of the first support leg 14 and the second support leg 23 are provided, which can form two spaces to accommodate the door frame 5, thereby realizing the crossing of the double door frame 5 structure.

[0028] Specifically, when it is necessary to use a flatbed truck to transfer materials, first place the ramp assembly with hook 41 near the door frame 5, then connect the intermediate transition assembly with the ramp assembly with hook 41, keeping the first support leg 14 and the second support leg 23 on both sides of the door frame 5 respectively, and finally install another ramp assembly with the intermediate transition assembly. At this time, the door frame 5 has formed a structure with uphill, crossing and downhill sections, which facilitates the transition of the flatbed truck.

[0029] In Embodiment 2 of the marine transfer device of the present invention: The door frame has two forms: double-door frame and single-door frame. This embodiment applies to the single-door frame form. Specifically, the structure in this embodiment is largely the same as that in Embodiment 1 of the marine transition device, except that it no longer includes the intermediate transition component. Figure 5 As shown, the marine transition device in this embodiment contains only two ramp components.

[0030] When using, first place the ramp assembly with the hanging ring on one side of the door frame, then place the other ramp assembly on the other side of the door frame, ensuring the hook and hanging ring are engaged. It is important to note that at this point, the locking mechanism on the ramp assembly must ensure that one of the hooks is engaged and the other is engaged.

[0031] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
