Description

Technical Field

[0001] This utility model relates to the field of container ships, specifically to the stern lashing bridge structure of a large dual-fuel container ship. Background Technology

[0002] Container lashing bridges are installed on the decks of large container ships. Equipped with eye plates, D-rings, or rotatable eye plates, they allow for the lashing of higher stacks, improving container stack stability and enabling the ship to carry more payload. Laddering bridges can be designed as internal or external lashing systems. External lashing systems secure the lifting side of the container, rather than the compressive side, reducing both lifting and compressive forces. Compared to internal lashing systems, external lashing systems better distribute the weight of the container stack, allowing for the safe loading of more containers.

[0003] As container ships rapidly become larger, the size of lashing bridges is also increasing. Currently, container lashing systems typically use methods such as stacking cones, lateral and longitudinal connecting plates, twist locks, and bridge locks for connection and stabilization. These systems are complex in structure and involve cumbersome operation procedures, resulting in long loading and unloading cycles at ports and increased operating costs.

[0004] With the significant reduction in the lateral acceleration coefficient of containers in the standards, it is imperative to research a large container ship lashing system that is compact in structure, optimizes lashing elements, facilitates lashing operations, saves loading and unloading time and efficiency, and provides secure lashing. Summary of the Invention

[0005] To adapt to the trend of larger container ships, this utility model provides a compact, safe, and flexible stern lashing bridge structure for large dual-fuel container ships.

[0006] The technical solution adopted by this utility model is as follows:

[0007] The stern lashing bridge structure of a large dual-fuel container ship includes two vertical side plates, which are distributed along the width of the container ship. Multiple platform plates are installed between the two side plates, with the width of the platform plates corresponding to the width of the side plates. The vertical spacing between adjacent platform plates corresponds to the height of the container. Multiple vertical square tubes are installed on both sides of each platform plate, symmetrically distributed at equal intervals on both sides. The spacing between adjacent square tubes on the same side corresponds to the width of the container. The bottom of each square tube is fixedly welded to the hull structure, and the sides of each platform plate are welded and fixed to the vertical square tubes. Two shear walls are distributed between the plates, and the two shear walls are spaced apart along the width direction of the hull on the same side of the lashing bridge. The bottom of the shear walls is fixedly welded to the hull structure. Platform plate side plates are installed between two adjacent platform plates. The platform plate side plates are distributed on both sides of the platform plate and are simultaneously welded and fixed to the upper and lower platform plates. Each platform plate side plate is provided with multiple operating holes evenly distributed along the width direction of the hull. There is one operating hole between two adjacent square tubes. Two sets of lashing eye plates are installed on the upper part of each square tube at the corresponding positions of the upper two platform plates. The two sets of lashing eye plates are distributed on both sides of the square tube along the width direction of the hull.

[0008] Furthermore, the uppermost two platform panels have a binding rod storage structure installed on their side panels.

[0009] Furthermore, the platform plate is provided with equally spaced through holes, and a channel grid is installed on each through hole. The channel grid is rotatably supported in the through hole of the platform plate by a rotating shaft.

[0010] Furthermore, an escalator is provided at the channel grille, and the escalator connects the upper and lower platform panels.

[0011] Furthermore, cold box sockets are fixedly installed on the side panels of the two lower platform layers.

[0012] Furthermore, railings are installed on both sides of the top surface of the platform plate.

[0013] Furthermore, the side plate is provided with multiple passage holes, each passage hole corresponding to the platform plate of each layer.

[0014] Furthermore, the square tube and the two sides at the bottom of the shear wall are reinforced by welding to the hull structure through ribs.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting two shear walls, the main support of the entire lashing bridge structure is achieved by using the shear walls and a pair of vertical side plates, and the auxiliary support of the lashing bridge platform plate is achieved by using vertical square tubes. Its structure is compact and simple. At the same time, the square tubes and lashing rods form a lashing system to achieve the lashing of stacked containers. By setting the position of the lashing eye plates on the uprights, a more flexible lashing method is achieved.

[0016] The platform and railings create a multi-level passageway between a pair of side panels, facilitating passage and operation between containers of different stacking heights. The installation of through holes and passageway grilles allows for easy access for personnel at various locations within the lashing bridge. The platform side panels also feature through holes to facilitate container handling and to reduce the weight of the lashing bridge, thus achieving lightweight design. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0022] As shown in the figure, the stern lashing bridge structure of a large dual-fuel container ship is installed at the stern and includes two vertical side plates 1. These two side plates 1 are distributed along the width of the container ship, and their bottoms are fixedly welded to the hull structure and reinforced by welding reinforcing plates. Multiple platform plates 2 are installed at equal intervals between the two vertical side plates 1. The width of the platform plates 2 corresponds to the width of the side plates 1, and the vertical spacing between adjacent platform plates 2 corresponds to the height of the containers. The multiple platform plates form multiple horizontal channels between the two side plates, facilitating personnel to perform lashing or maintenance operations on the containers at each level.

[0023] Two shear walls 3 are distributed between the two side plates 1. The two shear walls 3 are distributed at intervals along the width direction of the hull on the same side of the lashing bridge. The bottom of the shear wall 3 is fixedly welded to the hull structure and reinforced with ribs. The shear wall 3 is welded to the corresponding platform plate 2. The shear wall 3 is the main reinforcement structure of the lashing bridge.

[0024] Multiple vertical square tubes 4 are installed on both sides of the platform plate 2. These tubes are symmetrically distributed at equal intervals on both sides of the platform plate, with the spacing between adjacent tubes on the same side corresponding to the width of the container. The bottom of each square tube 4 is fixedly welded to the hull structure, and the sides of each platform plate 2 are welded to the vertical square tubes 4. The square tubes 4 provide auxiliary support and fixation for the platform plate. Platform plate side panels 5 are installed between adjacent platform plates. These side panels 5 are distributed on both sides of the platform plate 2 and are welded to both the upper and lower platform plates 2. Each side panel 5 consists of two C-shaped plates. The upper and lower sides of the C-shaped plates are welded to the upper and lower platform plates respectively for support. The sides of the C-shaped plates are welded to the corresponding square tubes 4. The two C-shaped plates on the same side form an elliptical passageway 6, facilitating personnel operation of the container. To improve safety, railings 11 are installed at the C-shaped passageway. This structure of two C-shaped plates effectively supports the platform plate vertically and allows for material reduction, achieving weight control.

[0025] To facilitate movement between upper and lower platforms, multiple passage holes 7 are provided on the side panel 1, each corresponding to a platform panel 2 on each level. Each platform panel 2 has multiple passage holes, and a passage grille 8 is installed on each passage hole. The passage grille 8 is rotatably supported within the passage hole of the platform panel via a pivot. Under normal conditions, the passage grille 8 is closed, allowing people to walk on the same level. When it is necessary to move between upper and lower levels, the passage grille 8 is opened, and an escalator 9 is provided at the passage grille 8, connecting the upper and lower platform panels for passage.

[0026] Cold box sockets 10 are installed on the lower two platform plates of the binding bridge for powering the cold box. Multiple sets of binding eye plates 12 and binding rod storage structures are welded onto the corresponding square tubes on the upper two and lower two layers of the binding bridge. Binding rod storage structures contain binding rods 13, which can be used for binding in cases of packing at different heights.
