Abstract
Description
Technical Field
[0001] This invention belongs to the field of container technology, and in particular relates to a method and system for loading large vehicles onto bulk cargo ships. Background Technology
[0002] The global automotive production and consumption market is increasingly geographically separated, with emerging automotive producing countries, represented by China, gradually becoming the core force in global automotive exports. According to industry statistics, China has ranked first globally in automotive exports for many consecutive years, with export destinations covering dozens of countries and regions in Europe, Southeast Asia, the Middle East, and South America. The transoceanic transport of large quantities of vehicles heavily relies on maritime shipping channels, directly driving the expansion of the vehicle shipping market.
[0003] Container shipping, limited by internal space, makes it difficult to directly load medium and large vehicles, often requiring disassembly or special modifications. This not only increases operational difficulty and cost but may also affect vehicle quality. While car carriers can transport various types of vehicles, their port adaptability is poor, heavily reliant on dedicated car carrier terminals. For small-batch transport, the high loading costs and poor economic viability deter many car manufacturers. To address these issues, a loading process for large vehicles on bulk cargo ships has been developed. Summary of the Invention
[0004] This invention addresses the shortcomings of existing technologies by providing a method and system for loading large vehicles onto bulk cargo ships.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for loading large vehicles onto bulk cargo ships, comprising the following steps:
[0006] S1. Based on the size of the large vehicle to be transported and the space of the ship's hold, conduct layout planning to determine the loading positions of its front and rear wheels in the ship's hold;
[0007] S2. Prepare a retractable corner column folding box and a platform box, wherein a local reinforcement structure is provided at the bottom middle position of the retractable corner column folding box;
[0008] S3. Adjust the corner posts of the retractable corner folding box to the appropriate height according to the actual height of the vehicle and open it;
[0009] S4. Hoist and position the two retractable corner folding boxes to a predetermined position on the bottom plate of the bulk carrier's hold, which corresponds to the loading position of the front and rear wheels of the vehicle determined in S1, and the bottom plate of the hold is provided with fixing blocks arranged longitudinally along the box body and fixing points for secondary binding.
[0010] S5. The vehicle is hoisted onto the retractable corner folding box in a straddle position, with the wheels positioned at the center of the box and on the local reinforcement structure. The vehicle is then secured to the retractable corner folding box by tying.
[0011] S6. Hoist the platform box to the top of the retractable corner column folding box, and lock and fix the two at the corner position using a twist lock device;
[0012] S7. The top corner piece of the retractable corner folding box and / or the bottom corner piece of the platform box are connected to the fixing point in the cabin by means of iron chain for secondary binding and fixing.
[0013] Furthermore, in step S1, the layout is planned as a straddle-type layout, so that a retractable corner folding box is placed under the front and rear wheels of the vehicle respectively.
[0014] Further, in step S4, the two retractable corner folding boxes are positioned longitudinally side by side and spaced at a preset distance on the bottom plate of the ship's cabin.
[0015] In step S5, multiple vehicles are hoisted sequentially along the transverse direction of the retractable corner folding box. Each vehicle is straddled so that its front and rear wheels rest on two retractable corner folding boxes respectively, and is secured by binding tools.
[0016] Furthermore, after step S6, step S6a is also included: hoisting and fixing another vehicle onto the platform box to form a double-layer vehicle loading structure.
[0017] Furthermore, when not loaded with vehicles, the retractable corner folding box and platform box can be used as standard containers for loading bulk cargo or for stacked transportation.
[0018] Furthermore, during the hoisting of the vehicle, the retractable corner column folding box, and the platform box, the unloaded hoisting method was adopted.
[0019] A large vehicle loading system for bulk cargo ships, comprising retractable corner post folding boxes and platform boxes with height-adjustable corner posts, characterized in that it further includes:
[0020] The hold of a bulk carrier has fixing blocks arranged longitudinally along the hull and fixing points for secondary lashing on its bottom plate.
[0021] A lashing tool for securing the vehicle to the retractable corner folding box;
[0022] A connector is used to connect the top corner piece of the retractable corner folding box and / or the bottom corner piece of the platform box to the fixing point.
[0023] Furthermore, the retractable corner folding box has a local reinforcement structure at the bottom center to bear the concentrated load of the vehicle tires; the platform box and the retractable corner folding box are connected at the corner by a twist lock device; the retractable corner folding box and the platform box together serve as the fixed carrier of the vehicle.
[0024] Compared with the prior art, the present invention has the following advantages.
[0025] This invention uses retractable corner-fitting folding frame boxes and platform boxes as fixed carriers for vehicle transportation. The vehicle's wheels are positioned at the center of the box in a straddle-like manner. Next, the folding frame box and platform box are locally reinforced according to the loading position of the vehicle's wheels to meet the load-bearing requirements. Then, the vehicle is secured to the box by lashing. Finally, additional fixing points are added to the hull to further secure the box to the hull. This process and tool expand the transportation range of large vehicles and are simple to operate and convenient to load. Attached Figure Description

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0031] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0032] Depending on the context, words such as “if” or “suppose” used here can be interpreted as “when”, “in response to determination”, or “in response to detection”.
[0033] In the embodiments, large vehicles refer to vehicles with a length greater than 8m or a width greater than 2.4m.
[0034] like Figure 1-7 As shown in the specific embodiment: on the bottom plate of the ship's hold, fixing blocks are added along the longitudinal direction of the container to ensure that the container is fixed laterally; at the same time, fixing points are set for secondary binding work on the container.
[0035] 1. A bottom longitudinal beam is added to the middle of the retractable corner column folding box and the platform box to strengthen the structure and meet the requirements of concentrated load at the tire contact point during vehicle transportation. On the return trip, these two types of boxes can be used as standard containers for loading loose cargo, or stacked as a whole to reduce transportation costs.
[0036] 3. The folding box and platform box are securely connected and fixed at the four corners of the box body using standard twist lock devices, thereby ensuring the relative positional stability and structural integrity of the two during transportation and use.
[0037] 4. Depending on the vehicle's dimensions, place the containers at the front and rear wheel positions, using a straddle-style placement. This method reduces the number of containers needed, thereby lowering transportation costs.
[0038] 5. Both the vehicle and the container were lifted without load to ensure the safety of the lifting operation.
[0039] 5. Add fixing points on the hull to further secure the container to the hull.
[0040] 6. Loading process:
[0041] 1. Based on the number and size of the transport vehicles and the internal space of the ship's hold, conduct a scientific and reasonable layout plan and accurately arrange the loading positions of the vehicles.
[0042] 2. Based on the actual height of the transport vehicle, pull out the corner posts of the retractable corner folding box to the corresponding height and complete the opening operation to ensure that the folding box is in a suitable position for loading the vehicle.
[0043] 3. Using a lifting device, lift the two folding containers to their designated positions inside the ship's hold. The placement of the folding containers must be precisely determined based on the vehicle's front and rear wheel track to ensure stability for subsequent loading.
[0044] 4. Use a lifting device to lift the vehicle onto the folding box, and then use professional lashing tools and methods to securely fasten the vehicle to the folding box to prevent the vehicle from shifting during transportation.
[0045] 5. Using the lifting equipment again, lift the platform box to the top of the folding box, and use a standard twist lock to fix and lock the platform box and the folding box together to ensure that the connection between the two is tight and the structure is stable.
[0046] 6. If the loading process requires it, step 4 can be repeated to hoist another vehicle onto the platform box (or the designated location) and secure it in the same way.
[0047] 7. Secure the top corner pieces of the folding box and the bottom corner pieces of the platform box to the anchor points inside the ship's hold using chains to further enhance the stability of the entire loading structure within the ship's hold. Complete the loading of the vehicle into the ship's hold following the above methods and procedures.
