Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a stern transport structure of a ship and its installation method. Background Technology

[0002] As a massive and highly customized complex product, the construction environment of a ship differs significantly from that of a conventional fixed workshop. The densely packed compartments, narrow passageways, and numerous, interwoven decks inside the hull necessitate frequent handling of various tools (such as welding machines, torque wrenches, and high-pressure water guns) and consumable materials (such as welding rods, paint, and cables) required during construction. Simultaneously, to maintain a clean working surface and ensure the quality of subsequent construction processes, waste materials generated (such as welding slag, scrap, and packaging materials) must be promptly and thoroughly cleaned and removed from the ship.

[0003] In existing technologies, some ships employ a single-deck external platform at the stern to provide space for the temporary storage and transshipment of tools and waste, thereby improving the convenience of handling operations to some extent. However, for ships with multiple decks, such as PCTC (Pure Car and Truck Carrier) vessels, construction tools need to be transported to each deck, and waste also needs to be transported out from different decks, resulting in significantly longer transport routes and a substantial increase in transport volume. Traditional single-deck external platforms, due to their limited space and accessibility, are no longer sufficient to meet the efficient logistics needs of such ships.

[0004] Therefore, there is an urgent need for a ship stern transport structure and its installation method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a ship stern transport structure and its installation method, which has minimal impact on the ship structure, can meet large-scale transport needs, improves transport efficiency, accelerates the ship manufacturing cycle, and effectively avoids cross-interference between transport on different decks.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On one hand, a stern transport structure for a ship is provided, wherein multiple decks are provided within the ship's hold. This stern transport structure includes:

[0008] Multi-level work platforms are set up at intervals along the vertical direction, and the distance between two adjacent work platforms is the same as the distance between two adjacent decks. The first end of the multi-level work platforms is arranged in a stepped manner from top to bottom, and the second end of the work platform can be joined with any deck.

[0009] Multiple support frames correspond one-to-one with the multi-level working platform. The upper end of the support frame is connected to the corresponding working platform. The lowest support frame can be connected to the surface of the ship. Except for the lowest layer, several support frames are detachably connected to the working platform adjacent to them below.

[0010] Optionally, the work platform includes a connected support plate and a cantilever plate, with the support frame connected to the support plate and the cantilever plate located on the side of the support plate closer to the deck and able to be aligned with the deck.

[0011] Optionally, the support plate includes multiple support parts, which can be spliced ​​together between any two adjacent support parts.

[0012] Optionally, the support includes an outer frame and several first plates. The outer frame encloses an installation space, and the first plates are laid in the installation space and connected to the outer frame.

[0013] Optionally, the support frame includes multiple support rods spaced apart along the circumference of the work platform, with the support rods being coaxial with a support rod of an adjacent support frame.

[0014] Optionally, the support frame may also include multiple connecting rods, which extend horizontally or are inclined vertically, and any two adjacent support rods are connected by the connecting rods.

[0015] Optionally, a protective fence is installed on the work platform, extending circumferentially along the work platform.

[0016] On the other hand, a method for installing a ship stern transport structure is provided, applicable to the aforementioned ship stern transport structure, comprising the following steps:

[0017] S1. Install the lowest support frame on the ship's surface and connect the lowest working platform to the corresponding support frame;

[0018] S2. Connect all support frames except the bottom layer to the corresponding work platform;

[0019] S3. Install several support frames, except for the bottom layer, onto the adjacent working platform below them.

[0020] Optionally, the number of operating platforms shall not be less than three layers;

[0021] Step S3 specifically includes the following steps:

[0022] S31. Install several support frames, except for the bottommost and second-lowest layers, onto the adjacent working platform below them;

[0023] S32. Install the lower-level support frame onto the lowest working platform;

[0024] Alternatively, step S3 may specifically include the following steps:

[0025] Install the multiple support frames, except for the bottom layer, onto the adjacent working platform below them in a bottom-to-top order.

[0026] Optionally, the work platform is equipped with lifting lugs;

[0027] In steps S1 and S2, after the hoisting equipment moves the work platform to the corresponding support frame through the lifting lugs, the work platform is then connected to the corresponding support frame, and the hoisting equipment remains connected to the lifting lugs throughout the connection process.

[0028] In step S3, the hoisting equipment is controlled to move the connected work platform and support frame through the lifting lugs, and the hoisting equipment is always connected to the lifting lugs when the moved support frame is connected to the adjacent work platform below it.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] This invention provides a stern transport structure and its installation method. The lowest-level working platform is directly installed on the ship's surface via a support frame, while the remaining working platforms are installed on their respective adjacent working platforms via corresponding support frames. This arrangement ensures that only the lowest-level support frame of the entire stern transport structure is connected to the ship, significantly reducing the number of openings on the ship's surface, thus helping to maintain the ship's structural integrity and improving the safety of the transport process. Since some decks in the ship are movable, the working platforms are installed alongside these decks, effectively preventing them from interfering with deck movement and ensuring the decks remain usable.

[0031] The spacing between two adjacent work platforms is the same as the spacing between two adjacent decks. This means that a multi-level work platform can correspond one-to-one with some or all of the multi-level decks, allowing tools and waste generated on each deck to be transported layer by layer via the corresponding work platform. This not only meets large-scale transportation needs but also significantly shortens the transportation paths of tools and waste between decks, effectively improving transportation efficiency and accelerating the shipbuilding cycle. Furthermore, the first end of each multi-level work platform is arranged in a stepped manner, corresponding to a single deck. This ensures clear and defined transportation paths for tools and waste on each deck, helping to avoid cross-interference between different work platform layers and further improving transportation efficiency.

[0047] Example 1

[0048] like Figures 1 to 3 As shown, this embodiment provides a stern transport structure for a ship, which has minimal impact on the structure of the ship 100, can meet large-scale transport needs, improves transport efficiency, accelerates the manufacturing cycle of the ship 100, and effectively avoids cross-interference between transport on different decks.

[0049] See Figure 1 The ship's cabin is equipped with multiple decks. The stern transport structure includes a multi-level working platform 1 and multiple support frames 2. The multi-level working platform 1 is arranged vertically ( Figure 1 The multi-level work platforms 1 are spaced apart in the Z-direction, and the distance between two adjacent work platforms 1 is the same as the distance between two adjacent decks. The first end of the multi-level work platforms 1 is arranged in a stepped manner from top to bottom, and the second end of the work platform 1 can be joined with any deck. Multiple support frames 2 correspond one-to-one with the multi-level work platforms 1. The upper end of the support frame 2 is connected to the corresponding work platform 1. The lowest support frame 2 can be connected to the surface of the ship 100. Except for the lowest layer, several support frames 2 are detachably connected to the work platforms 1 adjacent to them below. The first end and the second end are respectively the work platforms 1 along their extension direction (Z-direction). Figure 1 The two ends of the X direction in the middle.

[0050] In the stern transport structure provided in this embodiment, the lowest-level working platform 1 is directly installed on the surface of the ship 100 via a support frame 2, while the remaining working platforms 1 are respectively installed on their adjacent lower working platforms 1 via corresponding support frames 2. This arrangement ensures that only the lowest-level support frame 2 of the entire stern transport structure is connected to the ship 100, significantly reducing the number of openings on the surface of the ship 100, which helps maintain the structural integrity of the ship 100 and improves the safety of the transport process. Since some decks of the ship 100 are movable, the working platform 1, by fitting together with the deck, effectively prevents the installation of the working platform 1 from affecting the movement of the deck, ensuring the normal use of the deck.

[0051] The spacing between two adjacent work platforms 1 is the same as the spacing between two adjacent decks. This means that each multi-level work platform 1 can correspond one-to-one with some or all of the multi-level decks, allowing tools and waste generated on each deck to be transported layer by layer via the corresponding work platform 1. This not only meets large-scale transportation needs but also significantly shortens the transportation paths of tools and waste between decks, thereby effectively improving transportation efficiency and accelerating the shipbuilding cycle. Furthermore, the first end of each multi-level work platform 1 is arranged in a stepped manner, each corresponding to a deck level. This ensures clear and unambiguous transportation paths for tools and waste on each deck, helping to avoid cross-interference between different work platforms 1 and further improving transportation efficiency.

[0052] The vessel 100 is equipped with an openable stern door. When the stern door is opened, the multi-layer deck inside the cabin is exposed, which not only allows the staff to quickly determine the installation position of the multi-layer work platform 1, but also provides space for the installation of the stern transport structure provided in this embodiment at the stern of the vessel 100.

[0053] In this embodiment, the PCTC ship has 8 decks inside the cabin and three working platforms 1. The lowest working platform 1 is paired with the fifth deck from the bottom. The stern transport structure provided in this embodiment can provide a channel for transporting tools to the fifth, sixth and seventh decks.

[0054] For example, the load capacity of the work platform 1 assembled with the fifth deck is 6 tons, the load capacity of the work platform 1 assembled with the sixth deck is 4 tons, and the load capacity of the work platform 1 assembled with the seventh deck is 2 tons. That is, the load capacity of the multi-level work platforms 1 decreases step by step from bottom to top.

[0055] See Figure 1 The first end of any layer of work platform 1 is relative to the first end of the adjacent work platform 1 below it in the deck direction ( Figure 1The multi-layer working platform 1 is arranged in a stepped manner from top to bottom at a predetermined distance in the negative X direction. The predetermined distance is determined according to the specific specifications of the vessel 100.

[0056] For example, the lowest working platform 1 is 5.6m wide and the preset distance is 1.6m.

[0057] In some embodiments, the lowest working platform 1 can be modified from an existing external platform, which not only helps to further reduce the number of openings on the hull surface of the ship's stern transport structure and reduce the impact on the overall structure of the ship 100, but also reduces the manufacturing cost of the ship's stern transport structure and improves installation efficiency.

[0058] Optionally, see Figure 1 and Figure 2 The working platform 1 includes a connected support plate 11 and a cantilever plate 12. A support frame 2 is connected to the support plate 11, and the cantilever plate 12 is located on the side of the support plate 11 closest to the deck and can be aligned with the deck. The deck is located inside the ship's hold. The support frame 2 is installed on the surface of the ship 100, so that after the support frame 2 is installed on the ship 100, there will be a certain gap between the support frame 2 and the deck. The support plate 11 can be installed on the support frame 2, and the cantilever plate 12 is located at the aforementioned gap, which can connect the support plate 11 to the deck, thereby ensuring that goods can be transported between the support plate 11 and the deck.

[0059] In this embodiment, see Figure 2 The support plate 11 includes multiple support parts 111, which can be spliced ​​together between any two adjacent support parts 111. This arrangement makes the support plate 11 a modular design, so that when manufacturing each support plate 11, multiple support parts 111 can be produced in the factory first, and then the appropriate number of support parts 111 can be selected and assembled on the construction site according to the installation position of each support plate 11. The operation is convenient and quick, which helps to improve the installation efficiency of the ship's stern transport structure.

[0060] Specifically, see Figure 2 The support section 111 includes an outer frame 1111 and several first plates 1112. The outer frame 1111 encloses an installation space, and the first plates 1112 are laid within the installation space and connected to the outer frame 1111. In addition to the support plate 11 as a whole, each support section 111 also adopts a modular design, which helps to further improve the installation efficiency of the ship's stern transport structure. The outer frame 1111 provides stable support for the installation of the several first plates 1112, ensuring the stability and reliability of the overall structure of the support section 111.

[0061] For example, the outer frame 1111 is made of steel with a rectangular ring cross-section, the first plate 1112 is made of steel plate, the first plate 1112 is welded to the inner wall of the outer frame 1111, and the outer wall of the outer frame 1111 is welded to the outer frame 1111 of the adjacent support part 111.

[0062] In this embodiment, see Figure 2 The cantilever slab 12 includes multiple second slabs 121, which are spliced ​​together, and some or all of the second slabs 121 can be connected to the support plate 11. This configuration makes the cantilever slab 12 a modular design, which helps to further improve installation efficiency.

[0063] Optionally, see Figure 1 and Figure 3 The support frame 2 includes multiple support rods 21 spaced apart along the circumference of the working platform 1, with each support rod 21 coaxial with one of the support rods 21 of an adjacent support frame 2. This arrangement allows vertical loads (such as gravity and live loads) to be directly transferred to the vessel 100 through the support rods 21, avoiding an increase in bending moment and shear force due to eccentricity. It also allows the multiple support frames 2 to resist lateral forces more evenly, thereby significantly enhancing the overall rigidity of the vessel's stern transport structure and improving the safety of the transport process.

[0064] Specifically, the outer skin of the vessel 100 is inclined, and the lower end face of the lowest support rod 21 is a slope, so that the slope can fit against the outer skin of the vessel 100 to ensure the reliability of the connection between the lowest support rod 21 and the vessel 100.

[0065] For example, the support rod 21 is made of steel pipe or channel steel. The lowest support rod 21 is welded to the ship 100. The lower ends of the support rods 21 of the remaining layers are all provided with angle steel. The angle steel is detachably connected to the adjacent working platform 1 by bolts.

[0066] In this embodiment, see Figure 1 and Figure 3 The support frame 2 also includes multiple connecting rods 22, which extend horizontally or are inclined vertically. Any two adjacent support rods 21 are connected by connecting rods 22. This arrangement allows the support frame 2 to form a frame structure, significantly enhancing the structural integrity and rigidity of the support frame 2 and improving safety during transportation.

[0067] Specifically, one or more connecting rods 22 are provided between two adjacent support rods 21. When there are multiple connecting rods 22, the multiple connecting rods 22 are arranged at intervals along the extension direction of the support rods 21, which helps to further enhance the structural integrity and structural rigidity of the support frame 2.

[0068] For example, the support rod 21 is made of steel pipe or channel steel, the connecting rod 22 is made of steel pipe or channel steel, and the connecting rod 22 is welded to the support rod 21.

[0069] Optionally, see Figure 1 A protective fence 3 is installed on the work platform 1, extending circumferentially along the work platform 1. This design not only helps ensure the safety of workers operating on the work platform 1, but also effectively prevents tools or waste materials from falling off the work platform 1, further improving safety during transportation.

[0070] For example, the protective fence 3 is composed of multiple welded steel pipes.

[0071] Example 2

[0072] like Figure 4 As shown, this embodiment provides a method for installing a ship stern transport structure, applicable to the ship stern transport structure of Embodiment 1, including the following steps:

[0073] S1. Install the lowest support frame 2 on the surface of the ship 100, and connect the lowest working platform 1 to the corresponding support frame 2.

[0074] Specifically, the lower end face of the lowest support rod 21 is cut into an inclined surface that matches the inclination of the vessel 100, and the lower end face of the lowest support rod 21 is welded to the surface of the vessel 100; a connecting rod 22 is installed between two adjacent support rods 21; then, the number of support plates 11 required for the lowest working platform 1 is determined, and the required number of support plates 11 are installed on the top of the lowest support rod 21.

[0075] S2. Connect all support frames 2 except the bottom one to the corresponding work platform 1.

[0076] S3. Install several support frames 2, except for the bottom layer, onto the adjacent work platform 1 below them, so that multiple work platforms 1 can be connected into a whole.

[0077] In this embodiment, the number of work platforms 1 is no less than three layers; step S3 specifically includes the following steps:

[0078] S31. Install several support frames 2, excluding the lowest and second-lowest layers, onto the adjacent working platform 1 below them;

[0079] S32. Install the lower support frame 2 onto the lowest working platform 1.

[0080] After step S31, the multiple support frames 2 and multiple work platforms 1, excluding the lowest support frame 2 and the lowest work platform 1, have been connected into a single assembly. In step S32, when connecting the next lower support frame 2 to the lowest work platform 1, the aforementioned assembly can be installed as a whole onto the lowest work platform 1. This operation significantly reduces the time spent working on the vessel 100, helping to improve installation efficiency and safety.

[0081] In other embodiments, the number of work platforms 1 is not less than three layers; step S3 specifically includes the following steps: installing multiple support frames 2, except for the bottom layer, onto the adjacent work platforms 1 below them in a bottom-to-top order.

[0082] Specifically, the second-lower-level support frame 2, together with the corresponding working platform 1, is installed onto the lowest-level working platform 1, thus completing the installation of the second-lower-level support frame 2 and the second-lower-level working platform 1 on the vessel 100; then, the next-lower-second-lower-level support frame 2, together with the corresponding working platform 1, is installed onto the next-lower-second-level working platform 1, thus completing the installation of the next-lower-second-lower-level support frame 2 and the next-lower-second-lower-level working platform 1 on the vessel 100; the installation sequence of the remaining support frames 2 is similar.

[0083] Optionally, see Figure 5 The working platform 1 is equipped with lifting lugs 4. In steps S1 and S2, the lifting equipment moves the working platform 1 to the corresponding support frame 2 via the lifting lugs 4, and then connects the working platform 1 to the corresponding support frame 2. During the connection process, the lifting equipment remains connected to the lifting lugs 4. In step S3, the lifting equipment moves the connected working platform 1 and support frame 2 via the lifting lugs 4, and when the moved support frame 2 connects to the adjacent working platform 1 below it, the lifting equipment remains connected to the lifting lugs 4. This operation not only helps to improve the convenience of installing the working platform 1 and support frame 2, but also ensures the stability of the working platform 1 during connection, thus improving the safety of installation.

[0084] For example, the lifting equipment is equipped with a hook that can be connected to the lifting lug 4.

[0085] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
