Description

Technical Field

[0001] This application belongs to the field of ship transportation technology, and in particular relates to a shipboard timber storage rack. Background Technology

[0002] The existing semi-submersible vessels lack dedicated storage racks for heavy cargo loading pallets, relying instead on direct stacking combined with steel cutting and welding for fixation. This method has several significant drawbacks. Firstly, it poses a prominent safety risk. When the semi-submersible vessel submerges, the stacked pallets become submerged in water. If the steel fixing is not secure or lacks strength, the pallets can easily scatter and float, becoming obstacles in anchorages and waterways, affecting normal operations. Secondly, it results in severe efficiency losses. Stacking pallets requires multiple people working together, and the cutting, welding, binding, and subsequent dismantling of the steel consume a significant amount of manpower and time, directly reducing the loading and transportation efficiency of the semi-submersible vessel. Furthermore, when transferring pallets from the cargo deck to the fore and aft decks, a small number of pallets need to be individually bundled and hoisted, lacking a convenient transfer method, further contributing to low transfer efficiency.

[0022] This embodiment provides a marine timber storage rack, such as Figure 1 As shown, it includes: a base plate 1, a sleeve 2, a side plate 3, and several long-side connecting rods 4.

[0023] The long side of the base plate 1 extends along the X direction, and the wide side of the base plate 1 extends along the Y direction, with the X direction perpendicular to the Y direction.

[0024] like Figures 2-3 As shown, the sleeve 2 is fixed at both ends of the long side of the base plate 1. The sleeve 2 is hollow and extends along the Z direction, which is perpendicular to the X and Y directions. The side of the sleeve 2 facing the center of the long side of the base plate 1 has an avoidance notch 21. The side wall of the sleeve 2 has a waist-shaped hole 22 with the depth direction along the Y direction and the length direction of the waist-shaped hole 22 along the Z direction.

[0025] like Figure 1 As shown, the two ends of the long side connecting rod 4 are respectively detachably connected to the side plates 3 on both sides of the base plate 1 along the X direction.

[0026] like Figure 1 As shown, side plates 3 are connected to both sides of the base plate 1 along the X direction; as Figure 4 As shown, the side plate 3 includes mounting tubes 31 fixed to both sides of the side plate body 30 along the Y direction. The mounting tubes 31 are inserted into the sleeve 2 and connected to the sleeve 2 via connectors passing through the oblong hole 22.

[0028] In an alternative embodiment, such as Figure 1 , Figure 7 As shown, the marine timber storage rack also includes diagonal braces 5, with both ends of the diagonal braces 5 detachably connected to the mounting tube 31 and the long side of the base plate 1. In this embodiment, the diagonal braces 5 form a triangular structure by connecting with the mounting tube 31 and the long side of the base plate 1, thereby improving the deformation resistance of the storage rack during handling and stacking, and significantly enhancing the overall stability of the frame. Furthermore, the diagonal braces 5 are detachable, meaning they do not affect the folding function of the mounting tube 31.

[0029] In an alternative embodiment, such as Figure 4 , Figure 7As shown, the side plate 3 also includes a connecting rod block 32 and a first diagonal brace connecting block 33. The connecting rod block 32 and the first diagonal brace connecting block 33 are fixed to the side of the mounting tube 31 facing the center of the long side of the base plate 1. The connecting rod block 32 is used for the detachable connection of the long side connecting rod 4, and the first diagonal brace connecting block 33 is used for the detachable connection of the diagonal brace 5. It can be understood that a second diagonal brace connecting block 12 can be provided on the corresponding long side of the base plate 1 for the detachable connection of the diagonal brace 5. In this embodiment, the setting of the connecting rod block 32, the first diagonal brace connecting block 33 and the second diagonal brace connecting block 12 facilitates the flexible assembly and disassembly of the long side connecting rod 4 and the diagonal brace 5, improving the ease of use.

[0030] In an optional embodiment, both the base plate 1 and the side plate 3 include several cross-fixed steel sections, and the connecting rod connecting block 32 and the first diagonal brace connecting block 33 are both cut steel sections. In this embodiment, most of the materials used for the marine timber storage rack are selected from steel sections, eliminating the need for specially purchased components, thus meeting the requirement of using locally sourced materials. The solution is highly feasible and has low manufacturing costs.

[0031] In one optional embodiment, the dimensions of the marine timber storage rack are designed based on the actual usage scenario and the size of the timbers, taking into account the need for a certain gap when placing the timbers and maintaining a certain distance from the frame structure. The external dimensions (length x width x height) L×W×H = 3720mm × 1800mm × 1482mm, and the internal dimensions (length x width x height) L×W×H = 3500mm × 1630mm × 3462mm. It can store timbers with a size of 3000mm*300mm*300mm and other commonly used sizes.

[0032] In an alternative embodiment, such as Figure 4 , Figure 7 As shown, the connecting block 32, the first diagonal brace connecting block 33, both ends of the long side connecting rod 4, and both ends of the diagonal brace 5 all have openings for detachable connection of the connecting parts, so as to quickly assemble and disassemble the connecting parts. In this embodiment, the connecting parts can be selected from screws, bolts, buckles, twist locks, or ropes.

It is understood that the size and position of the fork holes should meet the requirements of forklift operation. The spacing between adjacent forklift rectangular tubes 6 can be designed to be 1.07m, and the dimensions of the forklift rectangular tube 6 are designed to be 200mm*100mm*8mm, with an internal height of 84mm and a width of 184mm.

[0034] In an alternative embodiment, such as Figure 2 As shown, the marine timber storage rack also includes lifting rings 7, which are evenly distributed along the edge of the base plate 1 and fixed to the base plate 1. The lifting rings 7 are used for lifting, facilitating the lifting and relocation of the marine timber storage rack. Optionally, the lifting rings 7 can be selected with a load-bearing capacity of 8t.

[0035] In an alternative embodiment, such as Figure 2 , Figure 6 As shown, the base plate 1 includes first corner fixing blocks 11 located at the four corners of the base plate body 10. The first corner fixing blocks 11 have several through holes for ropes or buckles to pass through. And / or, the side panel 3 includes second corner fixing blocks 34 located at the top two corners of the side panel body 30 along the Z direction. The second corner fixing blocks 34 have several through holes for ropes or buckles to pass through. In this embodiment, the arrangement of the first corner fixing blocks 11 and / or the second corner fixing blocks 34 can satisfy both storage and idle stacking conditions. In the storage condition, storage racks are stacked when padding is placed in them. First corner fixing blocks 11 or second corner fixing blocks 34 are installed at the four bottom corners and four top corners of the storage racks. The storage racks are connected by intermediate twist locks, and the first corner fixing blocks 11 are fixed to the deck by bottom locks. In the idle condition, storage racks are stored without padding and need to be folded. Folded storage racks can be stacked on top of each other.

[0036] In an alternative embodiment, such as Figure 3 As shown, the marine timber storage rack also includes a plug-in guide plate 8, which is fixed to the top of the side wall of the sleeve 2 along the Z direction. The plug-in guide plate 8 is inclined from bottom to top along the Z direction away from the sleeve 2. In this embodiment, when the folded storage racks can be stacked on each other, the plug-in guide plate 8 on the sleeve 2 of the lower storage rack can guide the first corner fixing block 11 at the bottom of the upper storage rack to be stacked, preventing misalignment between the storage racks and improving the neatness of the stacking.
