[0002] With the rapid development of the global logistics industry, multimodal transport has been widely adopted in various transportation scenarios, achieving seamless integration of ocean, rail, and road transport. This transportation model places higher demands on the adaptability and versatility of logistics equipment, particularly in complex and changing temporary operating environments, which poses new challenges and demands on the functionality of container equipment. Containers and their associated platform equipment are gradually evolving from a single transportation function to a multifunctional, modular, and standardized one, aiming to improve resource utilization, transportation flexibility, and turnover efficiency.

[0003] Traditional containers, with their fixed structure and single function, are primarily designed for enclosed cargo transport. They struggle to adapt to diverse scenarios such as bulk cargo handling, equipment transfer, and temporary platform construction. They present significant limitations in height adjustment, platform deployment, reuse, and standardized stacking. For example, when loading heavy bulk cargo like steel coils on roll-on / roll-off vessels, to prevent overweight stacking and structural instability, they are typically stacked in stacks of only 3 or 4 coils, for a total height of approximately 4 meters. This often leaves significant unused space between the cargo hold and the cargo, resulting in wasted transport space. Similar issues are also common when loading bulky cargoes such as iron ore, soybeans, and corn. Due to their fixed structure, traditional containers are difficult to stack in small volumes during return trips or when empty. Existing containers struggle to maintain structural stability and maximize space efficiency during transport without compromising safety and stability. Summary of the Invention

[0029] The following description of exemplary embodiments of the present invention is made in conjunction with the accompanying drawings, and various details of the embodiments of the present invention are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0030] like Figures 1 to 11 As shown, an embodiment of the present invention discloses a container, including: a supporting pillar 1, the pillar 1 includes an upper pillar 11 and a lower pillar 12, a rotating shaft 121 is provided between the upper pillar 11 and the lower pillar 12, the bottom of the upper pillar 11 is hingedly arranged on the top of the lower pillar 12, and the upper pillar 11 has at least two relative positions, the first position is that the upper pillar 11 is parallel to the lower pillar 12, and the second position is that an angle a of 70-110 degrees is formed between the upper pillar 11 and the lower pillar 12; a lifting platform 2, the lifting platform 2 is slidably arranged on the pillar 1, and when the upper pillar 11 is in the first position, the lifting platform 2 can slide back and forth between the top of the upper pillar 11 and the bottom of the lower pillar 12; a locking member 3, the locking member 3 is used to fix the lifting platform 2 on the top of the upper pillar 11 or the bottom of the lower pillar 12.

[0031] The container of the present application is provided with a support 1 structure consisting of an upper support 11 and a lower support 12, combined with the rotation connection mode of the upper support 11 and the sliding of the lifting platform 2 between the supports 1, so that the container has multiple usage states. When transporting goods, the upper support 11 is placed in a first position parallel to the lower support 12, and the lifting platform 2 can slide freely within the entire length of the support 1, so as to adjust the height of the lifting platform 2 according to the transportation or operation needs to meet the space configuration requirements of different goods. For example, roll-on / roll-off goods and bulk cargo are placed under the lifting platform 2, and dry cargo containers are placed on the top of the lifting platform 2. While ensuring the stability of the structure during transportation, the efficiency of cabin space utilization is effectively improved. When the cargo is in an empty state where there is no need to transport goods, the upper support 11 is placed in a second position folded together with the lower support 12, and the lifting platform 2 moves to the bottom of the lower support 12. The entire container is in a folded state and stored as a platform container, which is convenient for transportation and stacking, and helps to realize the stacking and transportation of multiple containers and improve the efficiency of space utilization.

[0032] By switching the upper support 11 between different positions, the container can have multiple usage states. When the lifting platform 2 is located at the top of the upper support 11, the top support mode can be realized to support the upper load such as a dry cargo container or platform cargo, which is suitable for mixed transportation scenarios; when the lifting platform 2 is located at the bottom of the lower support 12, the platform is in a folded state, consistent with the structure of an ordinary container, which is convenient for transportation and stacking; when the support 1 is folded and the lifting platform 2 is retracted, a platform container can be formed to realize standardized stacking and transportation of multiple empty containers, saving space, occupying less cabin space, greatly saving costs, and improving return efficiency. The container of the present application can be converted between top support, flat bottom, folding and other modes, has strong functionality, and is suitable for multimodal transportation such as land, rail, and sea transportation; and the container structure is simple and flexible to operate, which greatly improves transportation efficiency and creates higher transportation benefits in the case of mixed transportation with coiled steel or similar goods. Empty containers are folded and multiple containers are stacked for return, which reduces cabin space occupancy and greatly saves transportation costs. The multi-purpose lifting platform 2 container, with functions for lifting, folding, and standardized stacking, is suitable for mixed transportation of diverse cargo, such as bulk cargo, equipment, and dry cargo containers. It significantly improves transportation efficiency and space utilization, reduces transportation costs, and meets the practical needs of diversified, efficient, and standardized development in modern logistics systems. Specifically, the angle a formed between the above-ground support 11 and the lower support 12 is 90 degrees, while the angle is 70-110 degrees.

[0033] When the upper support 11 is in the first position parallel to the lower support 12, the lifting platform 2 can slide freely within the entire length of the support 1, so as to adjust the platform height according to the transportation or operation needs to meet the space configuration requirements of different goods. For example, when a 5-meter-high container is placed with 3-meter-high goods, the lifting platform 2 moves to 3 meters high, thereby improving the efficiency of the space occupied by the goods. If a 5-meter-high container is stacked on top of the 5-meter-high container, the lifting platform 2 of the upper container can be adjusted to a 6-meter-high platform, thereby improving the space utilization when stacking containers.

[0034] Specifically, four pillars 1 are provided at the four corners of the lifting platform 2, and container walls can be set between adjacent pillars 1. Sliding channels 201 are provided at the four corners of the lifting platform 2, and a rotating shaft 121 is provided at the top of the lower pillar 12, and the upper pillar 11 rotates around the rotating shaft 121 at the top of the lower pillar 12. The locking member 3 can be one of a square pin, a buckle, a bolt, and a fixing belt. The bolt and the square pin pass through the lifting platform 2 and are set on the pillar 1; one end of the buckle and the fixing belt is set on the outer wall of the sliding channel 201, and the other end is set on the pillar 1, and the top and bottom of the pillar 1 are provided with fixed ends of the buckle and the fixing belt. The sliding channel 201 is set at the four corners of the lifting platform 2, and the opening direction of the sliding channel 201 is vertically upward.

[0035] Specifically, the container of the present application can be a frame container or a container with side walls. Side walls are provided between the upper pillar 11 and the lower pillar 12, and a bottom plate can be provided at the bottom end of the pillar 1.

[0036] like Figure 1 and Figure 4 As shown, when the upper support 11 is in the first position, and the lifting platform 2 moves to the top of the upper support 11, the container is in a top-supporting state, and then the lifting platform 2 is fixed to the top of the upper support 11 by the locking member 3 to achieve a rigid connection. After fixation, the length and width of the container of the present application are consistent with the ISO shipping container, which can meet the stacking size requirements of the ISO shipping container. In this way, on a roll-on / roll-off ship, when using the container of the present application, roll-on / roll-off cargo and bulk cargo (such as steel coils, iron ore, soybeans, etc.) are normally loaded under the lifting platform 2; and on top of the lifting platform 2, dry cargo containers can be loaded, similar to the use of ordinary container ships. Greatly increase loading efficiency. The degree range of the lifting platform 2 can be adjusted according to different needs, such as 1000mm to 4800mm.

[0037] like Figure 3 and Figure 5As shown, when upper support 11 is in the first position and lifting platform 2 is moved to the bottom of lower support 12, the container of the present application is similar to a conventional folding container. Lifting platform 2 is fixed to the top of upper support 11 by locking member 3, achieving a rigid connection. Once fixed, the length and width of lifting platform 2 are consistent with those of an ISO shipping container, meeting the requirements of ISO shipping containers and enabling stacking, ceiling suspension, floor suspension, cargo loading and transportation, etc.

[0038] like Figure 2 and Figure 6 As shown, when the upper support 11 is in the second position, the upper support 11 is folded and stored above the lifting platform 2 to form a platform container. Multiple platform containers are stacked at the folded upper support 11 positions at the four corners, and are locked one by one through twist lock connections to form a standard container. In this way, after the empty container is folded, multiple roof platforms can be stacked into a 40-foot ISO standard box size, which can be loaded and returned by container ships, saving space, taking up less space, and greatly saving costs. Similarly, the square pins of each support pillar 1 corresponding to the folded roof platform (i.e., platform container) can be one or more. Fork grooves 204, lashing points, etc. can be used. The container in the folded state can be used as an ordinary platform container to load goods and multimodal transport.

[0039] like Figure 7 and Figure 8 As shown, in an optional embodiment of the present invention, the pillar 1 also includes a locking pin 13, the upper pillar 11 is provided with a first hole 101 and a second hole 102, and the lower pillar 12 is provided with a third hole 103, the distance between the first hole 101 and the rotating shaft 121 is equal to the distance between the second hole 102 and the rotating shaft 121, when the upper pillar 11 is in the first position, the first hole 101 is connected to the third hole 103, and the locking pin 13 is inserted in the first hole 101 and the third hole 103, when the upper pillar 11 is in the second position, the second hole 102 is connected to the third hole 103, and the locking pin 13 is inserted in the second hole 102 and the third hole 103.

[0040] By providing the first hole 101 and the second hole 102 on the upper support 11 and the third hole 103 on the lower support 12, the locking pin 13 can be respectively in the first position where the upper support 11 and the lower support 12 are parallel and in the second position where they are vertically folded, so that the pin passes through the corresponding hole, thereby forming a mechanical lock, ensuring that the structure will not accidentally shake or deform during the conversion process or working state, thereby improving the overall load-bearing stability and impact resistance of the platform container and ensuring safe use. The present application adopts a simple and reliable pin positioning method. The operator only needs to align the hole and insert the pin to complete the positioning lock or release switch on site, without the need for complex tools or a lot of time. This greatly improves the efficiency of container state switching and is particularly suitable for use in environments where multimodal transport requires rapid loading and unloading and frequent changes in operating modes.

[0041] When the lifting platform 2 is in the roof support or stowed position, a latch physically locks the support pillar 1, preventing it from swinging or rotating unexpectedly. This enhances the support capacity and force balance of the entire platform. This is especially true when the platform is continuously loaded with high loads, such as dry cargo containers, as the latch effectively prevents platform instability and ensures the safety of multi-layer stacking and transportation. The latch and channel are standard mechanical structures with a simple design and low manufacturing cost, facilitating subsequent maintenance, replacement, and mass production. This facilitates the widespread deployment of this container platform system in practical applications, forming a standardized modular system.

[0042] Specifically, when the upper support 11 is in the second position, the distance between the first hole 101 and the rotation axis 121 of the lower support 12 is equal to the distance between the second hole 102 and the rotation axis 121 of the lower support 12 .

[0043] like Figure 8 、 Figure 9 and Figure 11 As shown, in an optional embodiment of the present invention, a hinge plate 111 is provided at the bottom of the upper pillar 11, the first channel 101 and the second channel 102 are located on the hinge plate 111, and a third groove 104 is provided at the top of the lower pillar 12, and the hinge plate 111 is rotatably set in the third groove 104 through the rotating shaft 121.

[0044] By centrally arranging the first and second holes 101, 102 at the bottom of the upper support 11 on the hinge plate 111, the locking hole and the rotation mechanism form an integrated structure, simplifying the structure of the connection portion of the support 1, effectively improving structural stability, and reducing the difficulty of manufacturing and assembly. The hinge plate 111 is arranged in the third groove 104 at the top of the lower support 12 via the rotating shaft 121, allowing the upper support 11 to flexibly rotate around the rotating shaft 121. At the same time, the third groove 104 contains and limits the rotating shaft 121, enhancing the anti-displacement capability of the rotating component and improving the anti-sway performance during use. The locking holes are centrally arranged on the hinge plate 111, so that the holes always maintain a fixed relative position with the rotation center. When rotated to a predetermined angle, such as parallel or vertical, the first or second hole 102 can automatically align with the third hole 103 on the lower support 12, facilitating the rapid insertion and positioning of the locking pin 13, thereby improving operational efficiency. Hinge plate 111 rotates within a groove, offering strong resistance to external impact. Even during transportation or operation, it is unlikely to loosen or deform, ensuring the safety and durability of the platform support structure. As a connecting unit, hinge plate 111 can be independently manufactured and modularly assembled with upper support column 11, enabling modular and standardized production of structural components, facilitating maintenance and replacement while reducing overall manufacturing costs.

[0045] Specifically, the hinge plate 111 is provided with a card slot, and a stacking block 112 is provided at the bottom of the upper pillar 11. The stacking block 112 is engaged with the card slot. When the upper pillar 11 is in the first position, the stacking block 112 supports the entire upper pillar 11, and the stacking block is against the lower pillar 11. The stacking block 112 eliminates the gap between the upper pillar 11 and the lower pillar 11, thereby increasing the force contact surface and enhancing the stability of the pillar splicing.

[0046] In an optional embodiment of the present invention, the lifting platform 2 is provided with a slider, and the pillar 1 is provided with a vertical slide groove. The slider is slidably set on the slide groove. A gap is provided between the slide groove of the upper pillar 11 and the slide groove of the lower pillar 12, and the gap height is less than the slider height.

[0047] A guiding cooperation relationship is formed between the slider and the vertical slide groove, which can realize smooth vertical sliding inside the pillar 1 structure, effectively preventing the platform from shaking or deflecting during the lifting process, and ensuring stability and safety during operation.

[0048] By setting a gap, it is convenient for the upper pillar 11 to be rotated and set on the lower pillar 12, so as to avoid the slide groove at the connection position between the upper pillar 11 and the lower pillar 12 hindering the rotation of the upper pillar 11. The gap height between the slide grooves of the upper and lower pillars 12 is less than the height of the slider. When the slider moves to the connection point of the pillar 1, it will be physically limited to prevent the slider from accidentally entering the structural gap area, thereby avoiding the lifting platform 2 from derailing or getting stuck in the transition section between the pillars 1, ensuring the sliding safety and reliability of the entire platform. The structure of the slider and the slide groove allows the lifting platform 2 to transfer the force to the pillar 1 body and evenly distribute it when it is subjected to load impact, such as when loading and unloading goods, thereby improving the overall pressure resistance and seismic resistance of the platform and enhancing the service life of the container.

[0049] In an optional embodiment of the present invention, the lifting platform 2 is provided with a sliding channel 201, through which the support 1 passes. The inner wall of the sliding channel 201 is provided with protrusions, which are evenly distributed along the axis of the sliding channel 201. The inner wall of the sliding channel 201 is provided with a strip-shaped notch that communicates with the outside world, and the length direction of the strip-shaped notch is the vertical direction.

[0050] A plurality of protrusions evenly distributed along the axial direction are provided in the sliding channel 201 to form a multi-point contact support structure, which can significantly enhance the guiding stability between the lifting platform 2 and the pillar 1, reduce the risk of shaking and deflection of the platform during the sliding process, and make the platform run more stable and smooth. The protrusions reduce the contact area between the sliding channel 201 and the pillar 1, reduce friction and wear rate, which is conducive to extending the service life of the platform and the pillar 1, and reduce the driving force requirement, thereby improving the lifting efficiency of the platform. The inner wall of the sliding channel 201 is provided with a vertical strip notch, which can discharge accumulated water, dust, and debris during the sliding of the platform, prevent the accumulation of foreign matter from affecting the sliding performance, and improve the adaptability and reliability of the structure in harsh environments such as ports, railways, and bulk terminals. The strip notch forms a ventilation channel, which helps to reduce the expansion pressure caused by high temperature inside the sliding channel 201, alleviate the problem of jamming or structural deformation caused by temperature difference, and improve the environmental adaptability and stability of the platform operation. The strip-shaped notch allows maintenance personnel to directly observe the internal status of the sliding channel 201, which is convenient for daily inspection and cleaning, and also convenient for maintenance and replacement of key components such as bumps, thereby improving the maintainability and utilization efficiency of the platform system.

[0051] like Figure 6 and Figure 9 As shown, in an optional embodiment of the present invention, the height calculation formula of the lower support 12 is: H=k*(d1+d2), wherein d1 is the thickness of the lifting platform 2, d2 is the thickness of the upper support 11 in the second position, k is the adjustment coefficient, and the value range of k is 1-1.1.

[0052] Through the above-mentioned formula design, when the upper pillar 11 is folded to the second position and the lifting platform 2 is at the lowest point, the height of the entire pillar 1 system matches the stacking thickness of the lifting platform 2, ensuring that the overall height of the container is reasonable in the "platform-type" folded state, meeting the stacking and transportation requirements of ISO standard containers, and facilitating the return of containers or the stacking of empty containers. Since the height design of the lower pillar 12 combines the physical dimensions of the lifting platform 2 and the upper pillar 11, the k value can be fine-tuned to accommodate manufacturing and assembly errors, ensuring the overall height consistency of the container in the folded state, and improving the versatility and standardization of containers in scenarios such as container ships, railway platforms, and yards. By scientifically setting the height of the lower pillar 12, the structure can maintain a minimum storage volume in the folded state, and multiple folding containers can be stacked within the allowable size range to avoid waste of transportation space due to local structural protrusions or inconsistent sizes, increase the density of empty container returns, and reduce transportation costs. The design allowable range of the k value is 1 to 1.1. While ensuring the overall structural height control, it provides a certain adjustment margin. It can be flexibly adjusted according to the thickness, tolerance requirements, structural reservation or mechanical design needs of the specific platform material, thereby enhancing the adaptability between the structural design and manufacturing process and the tolerance of engineering tolerances.

[0053] like Figure 1 、 Figure 7 and Figure 8 As shown, in an optional embodiment of the present invention, the locking member includes a square pin or multiple square pins, which pass through the lifting platform and are arranged on the pillar. A groove is provided on the side of the lifting platform, and the square pin is located in the groove.

[0054] Specifically, the locking member 3 includes a first square pin 31 and a second square pin 32. The first square pin 31 passes through the lifting platform 2 and is arranged on the pillar 1. The second square pin 32 passes through the lifting platform 2 and is arranged on the pillar 1. The length direction of the first square pin 31 and the length direction of the second square pin 32 intersect with each other at a certain angle or are perpendicular to each other.

[0055] Since the two square pins are arranged in mutually perpendicular directions in space, a bidirectional locking structure is formed, which significantly enhances the stability of the lifting platform 2 under transportation loads, mechanical vibrations or operational impacts, and prevents the lifting platform 2 from loosening, shaking or shifting during use, ensuring transportation and operational safety. The first square pin 31 and the second square pin 32 arranged vertically and crosswise form an "L-shaped" locking path, which can provide higher structural shear resistance and connection rigidity, especially when the lifting platform 2 is in the top support mode and carries upper containers or equipment, it has stronger structural support capabilities and mechanical reliability. This double-pin structure is particularly suitable for transportation scenarios with severe vibration and impact, such as railways, sea transportation, and roll-on / roll-off ships. It can achieve double insurance fixation of the platform during transportation, effectively avoiding platform collapse or cargo slippage due to single point failure during transportation, and improving the safety factor of the entire loading system. The two square pins are inserted into the holes in different directions respectively. The operation is simple and clear, and the plugging and unplugging are convenient. It can realize manual quick disassembly and fixation, improving the use efficiency. At the same time, due to the use of mechanical latch locking method, it does not rely on complex mechanisms or energy drives, reducing maintenance costs and failure probability, and adapting to the use requirements of field or emergency operation scenarios.

[0056] Specifically, the first square pin 31 and the second square pin 32 can be respectively arranged at multiple corners or key stress points of the lifting platform 2 to form a multi-point, multi-directional linkage locking structure, effectively avoiding structural deformation under unbalanced load or concentrated load, and extending the service life of the platform.

[0057] like Figure 1 As shown, in an optional embodiment of the present invention, the lifting platform 2 is provided with a first groove 202 and a second groove 203, the first groove 202 and the second groove 203 are respectively located on adjacent sides of the lifting platform 2, and the first square pin 31 and the second square pin 32 are respectively located in the first groove 202 and the second groove 203.

[0058] By embedding the square pins in grooves on adjacent sides of the lifting platform 2, the square pins can be effectively prevented from being exposed during transportation, loading and unloading, and collisions, preventing deformation, loosening, or even loss of the square pins due to accidental collisions, thereby enhancing the reliability and durability of the locking structure. The first square pin 31 and the second square pin 32 are respectively placed in the first groove 202 and the second groove 203 of the platform, making the locking structure more embedded and compact, avoiding the appearance of protruding components on the platform's exterior, facilitating the stacking and storage of the platform, and the overall standardized size control of the containers, without interfering with the stacking or lifting operations of the containers. The square pins are located within the grooves, with a clear structural position, allowing operators to quickly locate them during installation or removal, reducing positioning and pin insertion time and improving on-site operation efficiency. The grooves also serve as guides and limiters, making the insertion and removal of the square pins smoother and the locking more secure. Since the square pins are housed within the grooves, they can effectively prevent problems such as accidental contact with the square pins or loosening or slipping due to vibration during transportation or operation, thereby improving the durability and reliability of the platform's locked state. The groove provides good physical protection for the square pin, reducing the direct impact of wind, sun, rain and other environmental corrosion on the square pin components, reducing the risk of failure such as wear and corrosion caused by external forces or the natural environment, thereby extending the service life of the locking member 3 and reducing maintenance costs.

[0059] Specifically, the first square pin 31 and the second square pin 32 pass through the sliding channel 201 along the length direction of the groove and are then arranged on the pillar 1. The first square pin 31 and the second square pin 32 are both provided with a handle 33.

[0060] like Figure 4 and Figure 6 As shown, in an optional embodiment of the present invention, the top surface of the lifting platform 2 is an arc-shaped top surface, and the middle thickness of the lifting platform 2 is greater than the thickness at both ends of the lifting platform 2.

[0061] The curved top surface structure has good force distribution characteristics, which enables the lifting platform 2 to effectively disperse concentrated loads when carrying heavy objects, reduce local stress concentration problems, thereby enhancing the overall compressive strength and structural stability of the lifting platform 2, and improving the safety and load-bearing efficiency of the lifting platform 2 during the support and stacking process. The curved design makes the surface of the lifting platform 2 slightly arched. When the platform is used for open-air operations or sea transportation, it can effectively promote the natural flow and discharge of rainwater or liquids along the two sides of the curved surface, avoiding problems such as water accumulation, rust, and ice on the platform surface, which is conducive to improving the applicability and weather resistance of containers in multiple climates and terrain conditions. Compared with flat structures, the curved top surface has a certain inhibitory effect on slight deformation or vibration during loading, which can prevent goods from slipping or shaking on the platform surface, and enhance the stability of goods on the upper part of the lifting platform 2. It is especially suitable for irregular goods in multimodal transport or equipment goods that require precise and stable transportation. Lifting platform 2's thick center and thin ends ensure thickness and strength in key load-bearing areas while also reducing overall weight through thinning at the edges, thereby enhancing lifting efficiency and overall loading flexibility. The curved top surface adapts to cargo with non-planar bottoms or container bottom beam grooves, creating a better contact and fit during loading, minimizing gaps and improving stability. It is particularly suitable for dry cargo boxes, pallets, or rolled materials.

[0062] like Figure 1 and Figure 4 As shown, in an optional embodiment of the present invention, the lifting platform 2 is a rectangular platform, and a fork groove 204 and a plurality of binding members 23 are provided on the side of the long side of the lifting platform 2. The binding members 23 are evenly distributed along the length direction of the lifting platform 2, and the fork groove 204 is located above the binding members 23.

[0063] By providing a standard fork slot 204 along the long side of the lifting platform 2, a forklift can be quickly inserted from the side for handling, lifting, or repositioning operations, eliminating the need for additional lifting equipment. This significantly improves the efficiency and flexibility of container loading, unloading, and transshipment, making it particularly suitable for short-duration, high-frequency loading and unloading operations. By evenly distributing multiple lashing elements 23, such as strap buckles and tensioning hooks, along the long side of the platform, cargo of various sizes, weights, and shapes can be effectively secured. This is particularly true when transporting easily displaced cargo, such as steel coils, machinery, and bulk cargo, significantly reducing the risk of cargo shifting, tilting, or collapsing, ensuring safety during transportation. Positioning the fork slot 204 above the lashing elements 23 not only does not interfere with their use but also facilitates direct forklift operations when the platform is unloaded or partially loaded. This allows for spatial independence between forklift operation and cargo securing, ensuring no interference, enhancing operational convenience and the reusability of the platform structure. The rectangular platform structure, combined with the standard placement of fork slots 204 and lashings 23, offers excellent standardization, facilitating efficient integration with existing intermodal logistics systems, such as container trucks, railroad flatbeds, and roll-on / roll-off vessels. It also supports the combination, stacking, and interchangeability of multiple platforms, enhancing the modular application capabilities of the transportation system. Lashings 23 and fork slots 204 along the long sides create a multi-point force support structure. When the lifting platform 2 is carrying heavy objects or experiencing uneven loads, these evenly spaced lashing points can disperse and constrain the force, thereby enhancing the overall rigidity and load-bearing balance of the platform structure.

[0064] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, it also includes a first crossbeam 4 and a second crossbeam 5. The first crossbeam 4 and the second crossbeam 5 are arranged between the two pillars 1, the first crossbeam 4 is located at the top of the upper pillar 11, the second crossbeam 5 is located at the bottom of the lower pillar 12, and the lifting platform 2 is located between the first crossbeam 4 and the second crossbeam 5.

[0065] By placing crossbeams between the pillars 1, a stable closed frame structure is formed at the upper and lower ends. This significantly improves the overall structural strength and torsional rigidity of the container under vertical loads and lateral shear forces, making it particularly suitable for complex operating conditions such as high-frequency lifting and heavy-load support. The lifting platform 2 is confined between the first and second crossbeams 4 and 5, effectively preventing it from sliding excessively or falling off. This physical limiter ensures that the lifting stroke remains within a reasonable range, improving operational safety and the platform's service life. The crossbeams not only serve as structural connectors but also as rigid support bases at the upper and lower ends of the lifting platform 2. When the lifting platform 2 is at the top or bottom, the crossbeams provide a rigid connection and uniform force distribution. Especially in the top-supported state, the lifting platform 2 and the first crossbeam 4 form a stable support surface for supporting upper dry cargo boxes or equipment and cargo. The crossbeams provide boundary guidance for the sliding trajectory of the lifting platform 2 and facilitate the installation of slideways, guide rails, or limiters. This improves the smoothness and stability of the lifting platform 2 during its upward and downward sliding, reduces jamming and offset, and enhances overall reliability.

[0066] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the lifting platform 2 includes a platform body 21 and a hollow column 22. The hollow column 22 is arranged at the four corners of the platform body 21, and the sliding channel 201 is arranged in the hollow column 22. Specifically, there is a variable fit gap between the support 1 and the sliding channel 201, and the fit gap range is 0-20mm. The top surface height of the hollow column 22 is higher than the top surface height of the platform body 21, and the bottom surface height of the hollow column 22 is the same as the bottom surface height of the platform body 21.

[0067] The hollow column 22 structure is covered with a sliding channel 201 to form a fully enclosed slide rail support structure. Compared with the open channel at the edge of the platform, it can significantly improve the vertical guidance and anti-swaying ability of the platform during the lifting process, avoid overloading or track deviation, and improve operational stability and safety of use. The hollow column 22 is set at the four corners of the platform, and the top surface is higher than the platform body 21, effectively forming an enhanced corner support structure. When the platform carries heavy objects or supports dry goods boxes, the force can be more directly and evenly transmitted from the hollow column 22 to the support 1, thereby avoiding large-scale deformation of the platform panel and improving the overall structural strength and bending rigidity of the platform. Since the top surface of the hollow column 22 is higher than the platform body 21, a limit, docking or connection structure can be set on the top surface of the hollow column 22, while the upper surface of the platform body 21 remains flat, which is convenient for loading items, stacking other containers or docking equipment legs, thereby improving the practicality and versatility of the upper surface of the platform.

[0068] Specifically, the hollow column 22 is integrally formed with the platform body 21. The hollow column 22 can also be independent of the platform body 21, possessing excellent modularity, facilitating the subsequent replacement, maintenance, or upgrade of different sliding channel 201 structures, such as roller guides and linear slides, thereby improving the maintenance efficiency and adaptability of the entire platform. The bottom surface of the hollow column 22 is maintained at the same height as the bottom surface of the platform body 21. When the platform is at its lowest or collapsed state, the overall platform structure can be flush with the bottom of a conventional platform or container, facilitating standardized stacking and forklift handling, and improving compatibility with existing logistics equipment.

[0069] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the lifting platform 2 is further provided with a reinforcement block 24, which is located on two adjacent side surfaces of the hollow column 22, and the two ends of the reinforcement block 24 are respectively connected to the lifting platform 2 and the top of the hollow column 22.

[0070] The reinforcement blocks 24 act like triangular supports, forming an effective, mechanically stable triangular structure during platform loading and lifting. This significantly enhances the structural stability of the connection between the hollow column 22 and the platform, preventing deformation, cracking, or displacement of the hollow column 22 under heavy loads, vibration, or tilting. The four corners of the hollow column 22 serve as key locations for the platform's vertical load bearing and sliding guidance. The addition of reinforcement blocks 24 effectively disperses and transmits vertical loads and lateral stresses, improving the platform's compressive strength and flexural rigidity under heavy loads, and enhancing its overall load-bearing capacity.

[0071] The reinforcement block 24 covers and connects the adjacent sides of the hollow column 22, which helps to limit the deformation of the top opening of the hollow column 22 and maintain the geometric accuracy of the sliding channel 201, thereby improving the smoothness and verticality of the platform when sliding on the guide rail, and reducing the risk of structural wear and jamming. During the frequent lifting and lowering of containers, transportation vibrations and multiple rounds of operations, the corner connections are the locations most susceptible to fatigue damage. The reinforcement block 24 can significantly reduce the degree of stress concentration and slow down the development of metal fatigue cracks, thereby extending the service life of the platform structure. The reinforcement block 24 can be fixed to the platform and the hollow column 22 by standard plate welding or screwing. It has a simple structure and is easy to manufacture. It is suitable for large-scale standardized assembly and helps to improve product consistency and production efficiency.
