Description

Technical Field

[0001] This invention relates to the field of container technology, and in particular to a new type of container with an octagonal column, 8 lifting points, and a length of 40 feet or more. Background Technology

[0002] With the rapid growth of global trade, container shipping has become a core mode of international logistics. However, during ocean shipping or multimodal transport, containers are often subjected to violent shaking or even capsizing due to external disturbances such as wind and waves, ship rolling, sharp turns, or emergency braking, resulting in serious accidents such as cargo damage, container deformation, and broken connecting parts.

[0003] Traditional container locks (such as turnlocks and bridge locks) can achieve a rigid connection between the upper and lower containers, but they lack effective buffering and self-resetting functions. When the container is subjected to lateral or longitudinal impacts, the rigid connection will directly transmit the impact force to the adjacent containers, causing concentrated stress and easily triggering a chain reaction of tipping over. In addition, existing horizontal connection methods (such as steel cables or rigid tie rods) require additional manual operation and cannot dynamically adjust the stress distribution between the containers, making them difficult to adapt to complex sea conditions. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a new type of container with 8 corner posts and 8 lifting points, which is 40 feet or more in length.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0022] like Figure 1 As shown, the container provided by the present invention can be a frame with 8 pillars and 8 lifting points. In practical applications, its length, height and width can be set according to the actual use scenario and material transportation scenario. The length, width and lifting point positions of this frame are constant. Example

[0023] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a new structure of a container with 8 corner posts, 8 lifting points, and a length of 40 feet or more.

[0024] Specifically, container A and the clearance groove A1 located at the bottom of container A; Support assembly 1 includes a corner post 11 on the outer wall of container A, a first slide groove 111 on the inner wall of corner post 11, a slide cylinder 12 inside corner post 11, a rotatable hook 121 at one end of slide cylinder 12, a second slide groove 122 inside slide cylinder 12, a piston 13 inside slide cylinder 12, and a limiting block 131 on the outer wall of piston 13. The limiting block 131 can slide along the inside of the first slide groove 111 and the second slide groove 122. The moving column 14 is located inside the slide cylinder 12, the flow channel 141 extends through both ends of the moving column 14, the slow flow channel 142 is located on the inner wall of the flow channel 141, the piston ball 15 is located inside the slow flow channel 142, the first elastic element 16 is located inside the slow flow channel 142, and the second elastic element 17 is located between the piston 13 and the moving column 14. An inner annular groove 143 is provided on the outer wall of the movable column 14 to cooperate with the hook 121.

[0025] Container A uses existing container technology, and then improves upon it. A cylindrical corner post 11 is fixedly installed on the outer wall of container A. A slide cylinder 12 is slidably installed inside the corner post 11. A rotatable hook 121 is installed at the upper end of the slide cylinder 12. The hook 121 is rotatably connected to the slide cylinder 12, and a torsion spring is provided at the connection. Its function is that when the slide cylinder 12 slides into the corner post 11, the inner wall of the corner post 11 will push the outer wall of the hook 121, and then the hook 121 will rotate inward. Meanwhile, the corner post 11 has a first vertically upward-facing groove 111 inside; the second groove 122 penetrates the slide cylinder 12, and the second groove 122 is a spirally upward-facing groove, allowing the limiting block 131 on the outer wall of the piston 13 to slide along the inside of the first groove 111 through the second groove 122. The purpose of this design is that when the slide cylinder 12 moves downward, because the first groove 111 cannot rotate, and the second groove 122 is a spirally upward-facing groove, the limiting block 131 on the outer wall of the piston 13 can slide upward along the first groove 111 without rotating. It should be noted here that the corner post 11 and the slide cylinder 1... 2. It can only slide up and down, not rotate. This technology can be achieved using keyway technology, which will not be elaborated here. Simultaneously, a movable column 14 is slidably installed below the corner column 11. A columnar flow groove 141 extends through both ends of the movable column 14. A slow-flow groove 142 is formed by an outward indentation near the lower end of the flow groove 141. A piston ball 15 and a first elastic element 16 are provided inside the slow-flow groove 142. The piston ball 15 can block the slow-flow groove 142 from the flow groove 141, and the first elastic element 16, which is a compression spring, is provided between the upper surface of the piston ball 15 and the inner wall of the slow-flow groove 142. An inner annular groove 143 is formed by an indentation in the lower outer wall of the movable column 14. When the movable column 14 presses down and contacts the upper surface of the slide cylinder 12, it pushes the slide cylinder 12 downward. Subsequently, the hook 121 is pushed inward by the inner wall of the corner column 11 and rotates inward, extending into the inner annular groove 143.

[0026] In a further preferred embodiment, the outer wall of the movable column 14 is recessed inward to form an inner annular groove 143, and at the same time, a limiting platform 144 is formed.

[0027] Among them, such as Figure 2As shown, four support components 1 are provided on both the left and right sides of container A, and a limiting platform 144 is formed below the inner ring groove 143. It should be noted that the corner post 11 is filled with liquid oil, and the connections between each component are sealed.

[0028] A second elastic element 17, which is a compression spring, connects the piston 13 and the moving column 14. When the piston 13 moves, it pulls the compression spring, and the piston 13 will be subjected to a reaction force. The advantage of this design is that the piston 13 has a downward tendency to move and slide downward along the second slide groove 122, which forces the slide cylinder 12 to lift upward, thus providing a lifting force on the upper container A. Combined with the weight of the upper container A, a stable state is formed. At the same time, when the upper container A is unloaded, the container A can be directly lifted, the slide cylinder 12 slides upward, and the hook 121 automatically disengages, realizing automatic unlocking.

[0029] When container A needs to be transported, after the first container A lands, the moving column 14 touches the ground and slides upward. Then, the moving column 14 pushes the slide cylinder 12 upward, and the hook 121 unfolds outward. During this process, the hydraulic oil also pushes the piston 13 upward. Subsequently, when containers A begin to be stacked on top of each other, the upper moving column 14 begins to contact the slide cylinder 12 of the lower container A and begins to push the upper moving column 14 upward. At the same time, it pushes the slide cylinder 12 in the upper container A to move upward. Then, as the container A continues to descend, it begins to push the slide cylinder 12 in the lower container A to move downward. The slide cylinder 12 in the lower container A begins to squeeze the internal hydraulic oil, and the hydraulic oil begins to push the piston 13 upward. At the same time, the hook 121 retracts inward and enters the inner ring groove 143. This is how the stacking amount of containers A is increased and the connection stability is improved. If container A encounters strong winds and waves and overturns, assuming it tilts to the right, the left side of the upper container A will tend to pull the left side of the lower container A. However, the sliding connection between the slide cylinder 12 and the corner post 11 will lock when pulled at a certain angle, thus connecting the upper and lower containers A. Simultaneously, if container A tends to slide, it will not shift due to the connection of the hook 121. Furthermore, multiple points are set on both sides of container A to distribute different forces, thereby ensuring the stability of container A during transportation. Example

[0030] Reference Figures 1-6 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0031] Specifically, eight support components 1 are symmetrically arranged on the outer wall of container A; Container A is equipped with eight lifting points A11; A connecting channel 18 connects the two symmetrical support components 1.

[0032] Four support components 1 are symmetrically arranged on the left and right sides of container A, and are connected to the two symmetrically arranged support components 1 by a connecting channel 18, that is, the liquid oil inside the two support components 1 can be connected to each other; the advantage of this design is that it allows the stacked containers A to be in a state of mutual restraint and adjustment.

[0033] Each support component 1 is equipped with a lifting point A11. The lifting point A11 adopts a conventional lifting method. The lifting point A11 is designed separately from the corner column 11, separating the lifting and weighing from the connection, thus reducing the breakage rate.

[0034] Preferably, a third elastic element 19 is provided between the inner wall of the movable column 14 and the corner column 11.

[0035] To ensure the position of the movable column 14, a third elastic element 19 is fixedly installed between the movable column 14 and the inner wall of the corner column 11. The third elastic element 19 is a compression spring. When the movable column 14 moves upward, it will pull the third elastic element 19, so that the movable column 14 is pulled downward. When container A is lifted, the movable column 14 can be pushed out of the corner column 11 by the third elastic element 19 and stacked on top of the container to ensure that there will be no clamping failure when container A is stacked. In addition, it should be noted that the radius of the connecting channel 18 is smaller than the difference between the inner and outer diameters of the slide cylinder 12. The advantage of this design is that when the slide cylinder 12 slides, it changes the internal flow direction of the liquid oil, and the flow rate of the liquid oil through the connecting channel 18 is limited. With the help of the spring, a certain damping effect can be formed.

[0036] During operation, when two containers A are stacked together, as in Example 1, when the upper container A wobbles (taking a rightward tilt as an example), the moving column 14 on the left side of the upper container A pulls the slide cylinder 12 on the left side of the lower container A. The slide cylinder 12 then tends to slide upwards. During this sliding motion, the internal space is released. Due to the presence of the second slide groove 122 and the second elastic element 17, the piston 13 on the right side is forced to move downwards, pushing the hydraulic oil downwards and flowing to the left side of the lower container A. At this time, hydraulic oil rushes in from the left side, pushing the left piston 13 upwards. Utilizing the characteristics of the second slide groove 122, the slide cylinder 12 is forced to pull downwards. Simultaneously, the piston 13 on the right side of the lower container A tends to move downwards, and the corresponding slide cylinder 12 tends to move upwards, increasing the force exerted on the upper container A by the right slide cylinder 12. By utilizing the flow of internal hydraulic oil at the moment of force application and the potential energy of the spring, the force causing the container A to tilt is offset, reducing the impact of external forces on the container A.

[0037] Assuming container A tilts at a small angle, taking the right side as an example, the right slide cylinder 12 slides downward by a certain displacement. At this time, the right piston 13 will move upward and pull the second elastic element 17. Meanwhile, the left slide cylinder 12 slides upward by a certain displacement, and the piston 13 moves downward by a certain displacement. At this time, the potential energy of the second elastic element 17 decreases, and the potential energy of the two second elastic elements 17 is unbalanced. The right second elastic element 17 continues to pull the piston 13, which is equivalent to giving the container A above a continuous upward force until the small angle tilt is restored.

[0038] In summary, when container A lands on the ground, the moving column 14 begins to slide inward into the corner column 11, simultaneously pushing the internal hydraulic fluid upward. This, in conjunction with the second elastic element 17, pushes the slide cylinder 12 out of the corner column 11. Subsequently, when container A presses down from above, the slide cylinder 12 begins to move downward. The internal hydraulic fluid exerts an upward pushing force, and the piston 13 begins to pull the second elastic element 17. At this time, the piston 13 tends to move downward, but due to the gravity of container A pressing against the slide cylinder 12, a state of equilibrium is reached.

[0039] The advantages of this solution are: 1. The spring and hydraulic oil can form a buffer structure. When the wind and waves blow container A, the hydraulic oil flow acts as a damper during the swaying process, preventing container A from making hard contact and swaying back and forth, avoiding direct impact on the structure during the swaying process, reducing direct impact, and reducing the risk of breakage of connecting parts; 2. The reset function uses the tension of the spring to ensure the balance of forces on both sides. When the wind and waves are strong enough to overturn container A, the spring will provide a reverse pulling force to prevent overturning. When there is a tendency to sway in the opposite direction during transportation, the spring can act as an aid to reset container A; 3. Container A uses gravity to hook hook 121 onto the moving column 14 of the upper container A. In this way, as long as container A does not move upward, container A will not detach from the lower container A. When unloading is required, the crane only needs to pull container A upward, and at the same time, the slide 12 moves upward, and the hook 121 naturally falls off, realizing the unloading of container A. Example

[0040] Reference Figures 1-9 This is the third embodiment of the present invention. This embodiment is different from the previous embodiment. The previous embodiment only ensured vertical stability and lacked horizontal connection, so it could not achieve multi-layer stacking.

[0041] Specifically, support components 1 are symmetrically arranged on one side of container A, and adapter components 2 are arranged on the other side of container A, with one set of support components 1 symmetrically arranged with one set of adapter components 2.

[0042] To ensure horizontal connectivity between containers A and to connect multiple containers A together as a whole, thus improving stability against wind and waves, a support component 1 is installed on the right side of container A, while an adapter component 2 is installed on the left side of container A. The main function of adapter component 2 is to connect the horizontally connected containers A together.

[0043] Preferably, the adapter component 2 includes a semi-circular groove A2 formed recessed on one side of container A, which can slide along the outer wall of corner post 11.

[0044] The inner wall of the semi-arc groove A2 fits against the outer wall of the corner post 11. When the container A is stacked, the side of the container A equipped with the support component 1 slides downward along the side equipped with the adapter component 2.

[0045] Furthermore, the semi-arc groove A2 is provided with abutting blocks 21, and there are two abutting blocks 21, with a fourth elastic element 22 provided between the two abutting blocks 21.

[0046] Two abutment blocks 21 are arranged below the semi-circular groove A2, and multiple fourth elastic elements 22, which are compression springs, are arranged in an array between the abutment blocks 21. The advantage of this arrangement is that... Figure 3 Therefore, when the corner post 11 of container A does not reach the bottom surface of container A, and the corner post 11 slides along the semi-circular groove A2, it will contact the abutment block 21. The advantage of this design is that when the two containers A are placed horizontally with overlapping parts, that is, the force of the wind and waves must be sufficient to overturn the weight of the two containers A for container A to possibly tip over. At the same time, the advantage of setting the fourth elastic element 22 between the abutment blocks 21 is that it can avoid shaking during transportation, prevent the two containers A from colliding hard, causing stress concentration and breakage at the contact point.

[0047] Push rods 23 are connected to the outer walls of the two abutting blocks 21; a connecting channel 18 is connected between the support component 1 and the adapter component 2, and the push rods 23 can slide along the inside of the connecting channel 18.

[0048] The push rod 23 can slide along the connecting channel 18, and the connecting channel 18 is connected to the interior of the slow flow channel 142. The advantage of this design is that if the top container A is at risk of tipping over to the right, the left container A will squeeze the corresponding abutment block 21, which is equivalent to applying a leftward pressure to container A, reducing the risk of tipping over.

[0049] Furthermore, the outer wall of the push rod 23 is provided with a hinge rod 24, and there are two hinge rods 24, which are respectively connected to the outer wall of the abutment block 21.

[0050] The contact block 21 and the push rod 23 are connected by a hinge rod 24. That is, when the two contact blocks 21 approach each other, the included angle of the hinge rod 24 becomes smaller, pushing the push rod 23 to move outward. When the two contact blocks 21 move away from each other, the included angle of the two hinge rods 24 becomes larger, and the push rod 23 moves towards the contact block 21.

[0051] Connecting channel 18 connects the two clearance slots A.

[0052] Push rod 23 slides along the inside of connecting channel 18, connecting the connecting channel into the inside of container A. The advantage of this design is that push rod 23 can connect the abutment block 21 to container A. At the same time, when the abutment blocks 21 move closer together, push rod 23 will push the liquid oil inside the connecting pipe 18 into the corner post 11, pushing the liquid oil upward. The piston 13 has an upward tendency, and the piston 13 pulls the second elastic element 17. The liquid oil also has a reverse pushing force, ensuring the stability of push rod 23 and counteracting the tendency of the two abutment blocks 21 to move closer together. The two abutment blocks 21 act on the adjacent container A in turn. The adjacent container A uses gravity to act on the two abutment blocks 21, ensuring that it will not tip over. Similarly, if there is a tendency to tip over to the left, container A will pull the slide cylinder 12 upward, piston 13 will tend to descend, and at the same time, there will be a tendency to pull the push rod 23 to move, starting to squeeze the two abutment blocks 21. The fourth elastic element 22 will start to exert force, reacting on the slide cylinder 12, and pulling container A, reducing the risk of tipping over.

[0053] In summary, the hydraulic oil and springs provide a damping effect. The displacement or reversal of container A drives the flow of the internal hydraulic oil, altering the forces acting on container A and thus correcting its position, ensuring its stability. This reduces stress concentration issues caused by container tipping over in existing technologies and minimizes the risk of connector breakage. Example

[0054] Reference Figure 1-9 This is the fourth embodiment of the present invention, which provides a reference design, such as... Figure 8 As shown, based on the technology of this invention, an existing structure is applied, including a container body A, a container floor A3, corner posts 11 mounted on the container floor A3, and side panels A4 mounted between the corner posts 11. This design strictly requires a frame with 8 pillars and 8 lifting points. In practical applications, its length, height, and width can be set according to the actual usage scenario and material transportation scenario. The length, width, and lifting point positions of this frame remain unchanged.

[0055] Regardless of variations in length, width, or height, the corner posts and lifting points on the frame of the container provided by this invention remain fixed. The distance between the two middle lifting points is between 20mm and 50mm. There is a movable or fixed crossbeam for water drainage between the upper middle corner posts, and a fixed crossbeam between the lower corner posts. The middle corner posts have no protrusions, either inside or out. Four height dimensions are available: 1717mm, 1921mm, 2591mm, and 2896mm, all of which can utilize the structural design of this invention. Through special design, the internal length of a 40-foot container is 50mm to 80mm longer than a standard container. Furthermore, containers with a height of 1717mm and 1921mm must be open-top containers, while containers with a height of 2591mm and 2896mm can be either open-top or closed-top. The standard load capacity of this type of container is 36-40.5 tons.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
