A ship sectional transportation combined bed and a ship transportation method

Abstract

The application discloses a ship section transportation combined bed and a transportation method. The ship section transportation combined bed comprises a gate frame and a storage platform which are connected separately. The gate frame is arranged below the storage platform. The storage platform is low in height, low in material consumption, and small in occupied space. The shipyard can produce the storage platform in large quantities, thereby meeting the demand for the number of beds when the amount of objects in the small assembly area is saturated. The gate frame is fully utilized in the transportation of different ship sections, thereby avoiding the waste of the idle gate frame. The ship section transportation combined bed can adjust the number of the gate frame and the bed on the site according to production needs, thereby improving the production efficiency and reducing the cost of ship manufacturing.

Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a modular transport bed for ship sections and a transport method thereof. Background Technology

[0002] Currently, the mainstream ship structure construction method generally involves disassembling the hull structure into individual segments. Specifically, based on factors such as the size of the hull structure and the difficulty of construction, the hull structure can be divided into three types: small segment assembly, medium segment assembly, and large segment assembly. These three types of structures can be fabricated in different areas according to their weight, etc. Small segment assemblies are then gathered in the medium segment assembly area for further fabrication, and finally transferred to the large segment assembly area for further segment construction. Finally, they are transported to the dock area for the final assembly, similar to "building blocks," to form the hull.

[0003] In this construction mode, the demand for the transfer of hull components is enormous. Based on the actual situation in shipyards, besides large flatbed trucks, the number of masts and masts also significantly limits material turnover efficiency. Masts are mainly used for supporting and transporting medium and large assemblies. Due to their small footprint and limited material requirements, they can be mass-produced quickly when material levels are saturated and masts are urgently needed to support sections, meeting production demands. However, the demand for masts decreases when production volume drops, resulting in a large number of idle and wasted masts. Masts are mainly used for stacking and transporting small assembly materials. Masts are generally 20m x 10m in length and width, and over 18m in height. Masts require a lot of material to manufacture and occupy a particularly large space, making mass production difficult for shipyards. This leads to a situation where the number of masts is insufficient to meet production needs when material levels in the small assembly area are saturated. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a modular bed for ship section transportation and a transportation method, thereby solving the technical problems in existing technologies where gantry frames used for medium and large-scale modular section transportation during temporary transport are easily left idle and wasted, and the number of beds assembled in temporary transport is insufficient to meet production needs.

[0005] To achieve the aforementioned objectives, the technical solution provided in this application is as follows:

[0006] A modular transport bed for ship sections includes a gantry and a storage platform. The gantry is used to support the intermediate and / or large sections of the transport ship. The gantry is located below the storage platform. The gantry and the storage platform are detachably connected. When the gantry is connected to the storage platform, the upper surface of the gantry is in contact with the lower surface of the storage platform.

[0007] In one embodiment, the gantry includes support columns and crossbeams, with two support columns vertically fixed to the lower surface of the crossbeams. The storage platform includes a rectangular frame, within which multiple mutually perpendicular horizontal and vertical bars are provided for placing small components. A snap-fit ​​element is provided on the lower surface of the frame, and the crossbeams are snap-fitted to the snap-fit ​​element.

[0008] In one embodiment, the snap-fit ​​component includes a first baffle and a second baffle disposed opposite to each other, the distance between the first baffle and the second baffle being greater than the width of the crossbeam, and when the gantry is connected to the storage platform, the crossbeam is located between the first baffle and the second baffle.

[0009] In one embodiment, the crossbeam is parallel to the wide side of the frame, and multiple snap-fit ​​components are symmetrically arranged below the long sides on both sides of the frame.

[0010] In one embodiment, a cylinder is fixedly mounted on the upper surface of the beam, and the frame is provided with a cylindrical hole corresponding to the cylinder. When the gantry is connected to the storage platform, the cylinder is inserted into the cylindrical hole.

[0011] In one embodiment, the diameter of the cylindrical hole is 20 mm larger than the diameter of the cylinder.

[0012] In one embodiment, the two cylinders are symmetrically arranged on both sides of the center line of the beam, and the two support columns are symmetrically arranged on both sides of the center line of the beam, with the distance between the two cylinders being greater than the distance between the two support columns.

[0013] In one embodiment, the height of the cylinder is less than 300 mm.

[0014] In one embodiment, the storage platform is provided with lifting lugs.

[0015] This application also provides a ship section transport modular bed and a transport method thereof, which, using the above-mentioned ship section transport modular bed, includes the following steps:

[0016] S1. Use a flatbed truck to lift the ship section transport assembly bed and transfer it to the crane in the group erection workshop. After all the groups are erected and lifted to the top of the bed, use a flatbed truck again to transport the ship section transport assembly bed to the storage area.

[0017] S2. After loading and unloading the small assembly components stored on the ship section transport combination bed, separate the storage platform from the gantry and stack the storage platform for storage.

[0018] S3. Use a flatbed truck to transport the gantry to the crane in the intermediate or large assembly workshop. After all the intermediate or large assemblies have been hoisted to the top of the gantry, use a flatbed truck again to transport the gantry to the storage area and unload all the intermediate or large assembly doors from the gantry.

[0019] Based on the above technical solution, the present invention has achieved the following beneficial effects:

[0020] The modular transport bed for ship sections in this application includes a detachable and connectable gantry and a storage platform. The storage platform is low in height, requires less material to manufacture, and occupies less space, allowing shipyards to mass-produce it and meet the demand for beds when the material volume in a small assembly area is saturated. The gantry is fully utilized in the transport of different ship sections, avoiding idle and wasteful use. The ship section transport method in this application allows for "tidal" adjustment of the number of gantry and beds on the site according to production needs, which not only improves production efficiency but also reduces shipbuilding costs.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0028] 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.

[0029] A modular transport bed for ship sections includes a gantry 1 and a storage platform 2. The gantry 1 is used to support the assembled and / or large assembled sections of the transport ship, such as... Figure 1 As shown, the gantry 1 is located below the storage platform 2. The gantry 1 and the storage platform 2 can be detached and connected. When the gantry 1 and the storage platform 2 are connected, the upper surface of the gantry 1 is in contact with the lower surface of the storage platform 2.

[0030] like Figure 2 As shown, the gantry 1 includes support columns 101 and a crossbeam 102, with the two support columns 101 vertically fixed to the lower surface of the crossbeam 102. Figure 3 As shown, the storage platform 2 includes a rectangular frame 201 with a thickness of 300mm. Multiple perpendicular horizontal and vertical bars are installed inside the frame 201 to hold small components. A snap-fit ​​connector is provided on the lower surface of the frame 201, and the crossbeam 102 can be snapped into place with the connector. Through the cooperation of the crossbeam 102 and the snap-fit ​​connector, the gantry 1 and the storage platform 2 can be detachably connected.

[0031] The crossbeam 102 is parallel to the wide side of the frame 201, and symmetrically arranged snap-fit ​​components are provided below the long sides on both sides of the frame 201. Each snap-fit ​​component includes a first baffle 203 and a second baffle 204 arranged opposite each other. The distance between the first baffle 204 and the second baffle 205 is greater than the width of the crossbeam 102. When the gantry 1 is connected to the storage platform 2, the crossbeam 102 is located between the first baffle 203 and the second baffle 204, supporting the storage platform 2 via the gantry 2 to raise it to the desired height. In this embodiment, the distance between the first baffle 204 and the second baffle 205 is 630mm.

[0032] In this embodiment, three snap-fit ​​pieces are evenly arranged along the long side of the frame 201. In other embodiments, four or five snap-fit ​​pieces may also be evenly arranged along the long side of the frame 201.

[0033] A cylinder 103 is fixedly installed on the upper surface of the crossbeam 102. A cylindrical hole 202 is provided on the frame 201 corresponding to the cylinder. When the gantry 1 is connected to the storage platform 2, the cylinder 103 is inserted into the cylindrical hole 202, thereby restricting the movement of the storage platform and making the structure of the ship section transport combination bed in this application more stable. In this embodiment, the diameter of the cylindrical hole 202 is 20mm larger than the diameter of the cylinder 103, facilitating the smooth insertion of the cylinder 103 into the cylindrical hole 202. Since a 300mm thick cork block is generally installed between the bottom plate of the section and the upper surface of the gantry 1 for cushioning when using the gantry 1 to support the sections, the height of the cylinder 103 is set to be less than 300mm to avoid the cylinder 103 affecting the support of the sections on the gantry 1. In this embodiment, the height of the cylinder 103 is 300mm.

[0034] To ensure that the force on the gantry 1 is even, two cylindrical columns 103 are symmetrically arranged on both sides of the center line of the crossbeam 2, and two supporting columns 101 are symmetrically arranged on both sides of the center line of the crossbeam 2, and the distance between the two cylindrical columns 103 is greater than the distance between the two supporting columns 101.

[0035] Lifting lugs 205 are provided on the storage platform 2 to facilitate the lifting of the storage platform 2 by the lifting equipment. In this embodiment, multiple lifting lugs 205 are symmetrically arranged on the outer side of the two long sides of the frame 201 so that the frame 201 can remain horizontal when the storage platform is lifted, which facilitates connection with the gantry 1.

[0036] This embodiment also provides a method for transporting ship sections, using the above-mentioned ship section transport combination bed, including the following steps:

[0037] S1. Use a flatbed truck to lift the ship section transport assembly bed and transfer it to the crane in the group erection workshop. After all the groups are erected and lifted to the top of the bed, use a flatbed truck again to transport the ship section transport assembly bed to the storage area.

[0038] S2. After loading and unloading the small assembly components stored on the ship section transport combination bed, separate the storage platform 2 from the gantry 1 and stack the storage platform 2 for storage.

[0039] S3. Use a flatbed truck to transfer the gantry 1 to the crane in the intermediate or large assembly workshop. After all the intermediate or large assemblies have been hoisted to the top of the gantry 1, use the flatbed truck again to transport the gantry 1 to the storage area and unload all the intermediate or large assembly doors on the gantry 1.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
