[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] Example 1

[0053] This embodiment provides a stacking device for a berthing structure, comprising a lower support 1, a middle support 2 and an upper support 3. Figure 1 As shown, the lower support 1 has two layers of first support structures 11 spaced apart from each other, the first support structures 11 are arranged one by one with the mooring structures, and the lower support 1 also includes at least one first vertical beam 12 and first horizontal beams 13 arranged in parallel at both ends of the first vertical beam 12, as shown in FIG. Figure 2 As shown, two first vertical beams 12 are arranged in parallel, and a first cross beam 13 is respectively arranged at the two ends of the two first vertical beams 12. The first supporting structure 11 is correspondingly arranged on the two first cross beams 13. The first supporting structure 11 includes at least two first supporting portions 111. In this embodiment, two first supporting portions 111 are arranged in the first supporting structure 11, and the two first supporting portions 111 are symmetrically distributed at the two ends of the first cross beam 13. The first supporting portion 111 adopts a supporting semi-ring, and the opening of the supporting semi-ring faces upward. The shape of the supporting semi-ring matches the shape of the mooring column 4 in the mooring structure, and is suitable for supporting the mooring column 4. Of course, the first supporting portion 111 can also be a circular ring, and the inner diameter of the circular ring matches the outer diameter of the mooring column 4, so that the mooring column 4 can be passed through and fixed. The lower support 1 also includes at least one supporting foot 14. In this embodiment, one supporting foot 14 is arranged and fixed on the first vertical beam 12. Figure 3 As shown, the connecting lines of the supporting foot 14 and the two ends of the first cross beam 13 below form a triangle, so that the supporting structure of the lower support 1 is more stable, and the supporting surface of the supporting foot 14 is welded or bolted to the deck surface of the hull.

[0054] like Figure 4 As shown, the middle support 2 includes a base 21 and two second support structures 22 horizontally spaced apart on the base 21. The base 21 is fixed on a transport device of the mooring post 4, for example, the transport device is a deck of a ship. The base 21 is welded by I-beams to form a rectangular frame structure. The frame structure is provided with transversely and longitudinally distributed fixing parts by I-beams. The second support structure 22 is fixed on the fixing parts. Any second support structure 22 includes two second support parts 221. The two second support parts 221 are spaced apart on the base 21 along the extension direction of the same mooring post 4. The second support part 221 is a support semi-ring. The support semi-ring matches the shape of the mooring post 4. The support semi-ring opens upward and is supported on the outer peripheral surface of the mooring post 4.

[0055] At least one of the second supporting structures 22 is provided with a limiting structure 23. In this embodiment, the limiting structures 23 are respectively provided on the two second supporting structures 22, and two limiting structures 23 are correspondingly provided on each second supporting structure 22. The two limiting structures 23 correspond one to one with the two second supporting portions 221 in the same second supporting structure 22. Figure 4As shown in the figure, the limiting structure 23 includes a second cross beam 232 and two second vertical beams 231. The two second vertical beams 231 are distributed on both sides of the second support portion 221 along a direction perpendicular to the extension direction of the mooring post 4. The second cross beam 232 is erected between the two second vertical beams 231. A placement space for the mooring post 4 is formed between the second cross beam 232 and the second support portion 221. In this embodiment, on the opposite side walls of the two second vertical beams 231 on the same side in the two limiting structures 23, C-shaped notches are respectively formed, and the notches are arranged oppositely. The second cross beam 232 is a rectangular pipe, and the outer dimensions of the rectangular pipe match the dimensions of the C-shaped notches. The second cross beam 232 is inserted into the notches of the two second vertical beams 231 in the limiting structure 23.

[0056] As Figure 5 shown, in two adjacent limiting structures 23 in the same second support structure 22, buffer pads 24 are arranged on the opposite side walls of the two second cross beams 232. The arm 42 protruding from the mooring post 4 is located between the two second cross beams 232. The arrangement of the buffer pads 24 avoids hard contact between the mooring structure and the cross beam when the mooring structure is displaced, causing damage. The buffer pads 24 can be rubber pads or other soft materials with a certain strength.

[0057] As Figure 6 shown, the upper support 3 includes a third support portion 31 and docking portions 32 symmetrically fixed at both ends of the third support portion 31. In this embodiment, the third support portion 31 is a support steel pipe, and the docking portions 32 are plate-like structures, symmetrically welded at both ends of the support steel pipe. As Figure 7 shown, docking holes 321 are respectively formed on each docking portion 32. The upper support 3 is arranged between the upper and lower mooring structures. The docking holes 321 on the docking portions 32 are correspondingly arranged with the bolt holes of the flange plates 41 on the mooring structures on the same side. Bolts sequentially pass through the bolt holes of the flange plates 41 and the docking holes 321, and the upper and lower mooring structures are fixedly connected together through the upper support 3.

[0058] In this embodiment, the upper support 3, the middle support 2, and the lower support 1 are all formed by combined welding of I-beams and rectangular pipes.

[0059] The stacking process of the two mooring structures is as follows:

[0060] Taking Figure 8 and Fig. 9 the states shown as an example, the middle support 2 is welded and fixed on the ship deck.

[0061] First, weld or bolt the lower support 1 and the middle support 2 to the ship deck, lift the berthing structure so that the berthing column 4 is higher than the second vertical beam 231, and use a crane to slowly and horizontally translate the berthing structure from the middle support 2 to the lower support 1, and stop the translation when the support arm 42 of the berthing structure reaches the center of the two second vertical beams 231. Slowly lower the berthing structure so that the berthing column 4 falls into the support semi-ring of the first support portion 111 in the first support structure 11 and the support semi-ring of the second support portion 221 in the second support structure 22;

[0062] At this time, the arm 42 of the mooring column 4 is located between the two limiting structures 23, and then the second cross beam 232 is inserted, and the side wall of the second cross beam 232 where the buffer pad 24 is arranged is arranged toward the arm 42, so as to form a longitudinal limit for the mooring column 4 and a lateral limit for the arm 42;

[0063] The end of the mooring structure away from the lower support 1 has a flange 41 facing upwards, and a docking portion 32 on one side of the upper support 3 is fixed on the flange 41;

[0064] The upper mooring structure is hoisted above the lower mooring structure, and the two mooring structures are arranged opposite to each other (such as Figure 8 As shown in the figure, one end of the mooring column 4 of the upper mooring structure fits in the supporting half ring of the first supporting part 111 in the upper first supporting structure 11, and the flange 41 of the other end of the mooring column 4 faces downward and is fixed on the other side docking part 32 of the upper support 3, and the two mooring structures are fixed together through the upper support 3, and the stacking is completed. By limiting the position of the lower mooring structure, the simultaneous limiting of the two mooring structures is achieved.

[0065] The process of disassembling the two berthing structures from the stacking device is the reverse process of the above stacking process, which will not be described in detail here.

[0066] The lower support 1 has two layers of first support structures 11 arranged at intervals, which are arranged one by one with the mooring structures and are suitable for supporting one end of the mooring column 4 of the corresponding mooring structure; the middle support 2 is fixed on the deck, and has two second support structures 22 arranged horizontally and at intervals, which are arranged correspondingly with the two mooring columns 4 of the mooring structure located at the lower layer and supported in the middle of the mooring columns 4; the upper support 3 is fixedly connected to two opposite flanges 41 on the upper and lower mooring structures. The two mooring structures are fixed together at one end by the opposite flanges 41, and the other ends are respectively overlapped on the two first support structures 11 on the lower support 1. The middle part is limitedly supported by the middle support 2 to avoid displacement during transportation, improve the stability of transportation, and the two mooring structures are arranged oppositely and stacked up and down to reduce the deck area occupied by the mooring structures, thereby improving the transportation quantity and transportation efficiency.

[0067] As a first replaceable implementation of Example 1, a limiting structure 23 may be provided on only one second supporting structure 22, and by limiting the longitudinal and lateral position of a mooring column 4, the overall limiting of the upper and lower mooring structures may also be achieved.

[0068] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
