Description

Technical Field

[0001] This invention relates to the field of container technology, and more specifically, to a container and a method for loading and unloading cargo from the container. Background Technology

[0002] A shipping container is a means of transportation that facilitates the loading and unloading of goods. It is a tool capable of carrying packaged or unpackaged goods and is easily handled by mechanical equipment. The greatest success of shipping containers lies in their standardization and the resulting comprehensive transportation system. A shipping container consists of a container body and two side doors located on either side of the body.

[0003] However, the containers in the relevant technologies require all side doors to be opened when loading and unloading goods, resulting in low efficiency, high labor intensity for loading and unloading personnel, and long loading and unloading time. Summary of the Invention

[0004] The main objective of this invention is to provide a container and a method for loading and unloading cargo from the container, in order to solve the problem in the related art that all side doors of the container need to be opened when loading and unloading cargo, resulting in low efficiency in loading and unloading cargo.

[0005] To achieve the above objectives, according to a first aspect of the present invention, a container is provided, comprising: a container body, the container body including a first side and a second side disposed opposite to each other, the first side being provided with a plurality of first loading and unloading ports communicating with the interior of the container body, the second side being provided with a plurality of second loading and unloading ports communicating with the interior of the container body, the plurality of first loading and unloading ports and the plurality of second loading and unloading ports being disposed in a one-to-one correspondence; a plurality of first side doors, which are rotatably disposed on the top of the container body, the first side doors covering or opening at least one first loading and unloading port; a plurality of second side doors, which are rotatably disposed on the top of the container body, the second side doors covering or opening at least one second loading and unloading port; and a plurality of transport pallets, which are spaced apart along the length of the container body on the bottom wall of the container body, a transport pallet being disposed correspondingly between each first loading and unloading port and each second loading and unloading port.

[0006] Furthermore, the container also includes multiple partitions installed inside the container body. The multiple partitions are spaced apart along the length of the bottom wall of the container body. The first side of the multiple partitions forms multiple first loading and unloading ports between the top and bottom walls of the container body, and the second side of the multiple partitions forms multiple second loading and unloading ports between the top and bottom walls of the container body. One partition separates two adjacent transport pallets.

[0007] Furthermore, the multiple partitions include multiple first partitions and multiple second partitions, which are arranged alternately along the length of the bottom wall of the container. Each first side door is closed or opened with two corresponding first loading and unloading ports, and each second side door is closed or opened with two corresponding second loading and unloading ports. A first elastic support is provided on the side of the container and on the first side of each second partition. The upper end of each first elastic support is hinged to the corresponding first side door, and the lower end of each first elastic support is hinged to the side of the container or the first side of the second partition. A second elastic support is provided on the side of the container and on the second side of each second partition. The upper end of each second elastic support is hinged to the corresponding second side door, and the lower end of each second elastic support is hinged to the side of the container or the second side of the second partition.

[0008] Furthermore, the upper end of each first elastic support is hinged to the corresponding first side door via a first hinge pin, and the lower end of each first elastic support is hinged to the side of the box or the first side of the corresponding second partition via a second hinge pin. When the first side door covers the first loading and unloading port, the first hinge pin is closer to the middle of the box than the second hinge pin. The upper end of each second elastic support is hinged to the corresponding second side door via a third hinge pin, and the lower end of each second elastic support is hinged to the side of the box or the second side of the corresponding second partition via a fourth hinge pin. When the second side door covers the second loading and unloading port, the third hinge pin is closer to the middle of the box than the fourth hinge pin.

[0009] Furthermore, the container also includes multiple auxiliary support frames pivotally mounted on the sides of the container body and on multiple second partition frames, each auxiliary support frame having a pivot axis extending vertically, and each auxiliary support frame having a retractable position located inside the container body and an auxiliary support position supported below the first side door.

[0010] Furthermore, each auxiliary support frame includes a pivot shaft that is swayably disposed on the side of the housing or on the second partition frame and a support frame connected to the pivot shaft. The support frame includes a first support rod connected to the upper end of the pivot shaft, a second support rod connected to the lower end of the pivot shaft, and a connecting rod connecting the first support rod and the second support rod. The length of the first support rod is greater than the length of the second support rod.

[0011] Furthermore, the upper ends of multiple first side doors are flip-up and mounted on the top of the box body. The auxiliary support frame includes multiple first pull members, one end of which is connected to the lower end of the first side door in a corresponding manner. The upper ends of multiple second side doors are flip-up and mounted on the top of the box body. The auxiliary support frame includes multiple second pull members, one end of which is connected to the lower end of the second side door in a corresponding manner.

[0012] According to a second aspect of the present invention, a method for loading and unloading cargo in a container is provided, which utilizes the aforementioned container to load and unload first cargo and second cargo. The method includes a loading step and an unloading step. The loading step includes: opening at least one of a plurality of first side doors of the container; loading the first cargo onto a first placement station of a transport pallet inside the container; obtaining first cargo information on the first cargo; transporting the first cargo from the first placement station of the transport pallet to a second placement station of the transport pallet, wherein the first and second placement stations are arranged along the width direction of the container; loading the second cargo onto the first placement station of the transport pallet inside the container; obtaining second cargo information on the second cargo. The unloading step includes: opening the corresponding first side door according to the second cargo information; unloading the second cargo from the first placement station; transporting the first cargo from the second placement station of the transport pallet to the first placement station of the transport pallet; and unloading the first cargo from the first placement station.

[0013] Furthermore, the loading step also includes: opening at least one of the multiple second side doors of the container that correspond one-to-one with the multiple first side doors; loading the first cargo into the second placement station of the transport pallet inside the container; obtaining the first cargo information on the first cargo; the transport pallet transporting the first cargo from the second placement station of the transport pallet to the first placement station of the transport pallet, and loading the second cargo into the second placement station of the transport pallet inside the container; obtaining the second cargo information on the second cargo; the unloading step also includes: opening the corresponding second side door according to the second cargo information; unloading the second cargo from the second placement station; the transport pallet transporting the first cargo from the first placement station of the transport pallet to the second placement station of the transport pallet, and unloading the first cargo from the second placement station.

[0014] According to a third aspect of the present invention, a method for loading and unloading cargo in a container is provided, wherein the container loading and unloading method comprises a loading step, the loading step comprising: opening all first side doors and loading multiple goods onto one of two placement stations of each transport pallet; detecting the weight of the goods on each transport pallet; and adjusting the position of the multiple goods on the corresponding transport pallet according to the weight of the goods on each transport pallet.

[0015] Furthermore, the step of adjusting the position of multiple goods on the corresponding transport pallet according to the weight of the goods on each transport pallet also includes: obtaining the center of gravity of all goods based on the weight of all goods; determining the difference between the center of gravity of all goods and the centerline of the container in the front-rear direction; and adjusting the position of multiple goods on the corresponding transport pallet according to the difference so that the difference is less than or equal to a preset threshold.

[0016] According to the technical solution of this invention, a container includes: a container body, multiple first side doors, multiple second side doors, and multiple transport pallets. The container body includes first and second sides arranged opposite to each other. Multiple first loading / unloading ports communicating with the interior of the container body are provided on the first side, and multiple second loading / unloading ports communicating with the interior of the container body are provided on the second side, with each of the first and second loading / unloading ports corresponding to one another. Multiple first side doors are foldable and mounted on the top of the container body, and each first side door can either cover or open at least one first loading / unloading port. Multiple second side doors are foldable and mounted on the top of the container body, and each second side door can either cover or open at least one second loading / unloading port. Multiple transport pallets are spaced apart along the length of the container body on the bottom wall, with one transport pallet corresponding to each first loading / unloading port and each second loading / unloading port. During loading operations, depending on the existing cargo inside the container, one of the multiple first side doors or multiple second side doors is opened, and the cargo is placed from the first or second loading / unloading port onto the transport pallet inside the container. During unloading operations, one of the multiple first side doors or multiple second side doors containing the goods to be unloaded is opened according to the location of the goods. The goods are then unloaded from the transport pallet inside the container through the first or second loading / unloading port. This allows for the opening of one of the appropriate number of first or second side doors as needed, eliminating the need to open all side doors during loading and unloading, thus improving efficiency, reducing the workload of loading and unloading personnel, and shortening the loading and unloading time. Therefore, the technical solution of this application effectively solves the problem of low efficiency in loading and unloading containers due to the need to open all side doors during loading and unloading in related technologies.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0063] like Figures 1 to 4As shown, the container in this embodiment includes: a container body 100, a plurality of first side doors 200, a plurality of second side doors 300, and a plurality of transport pallets 700. The container body 100 includes a first side and a second side arranged opposite to each other. A plurality of first loading / unloading ports 110 communicating with the interior of the container body 100 are provided on the first side, and a plurality of second loading / unloading ports 120 communicating with the interior of the container body 100 are provided on the second side. The plurality of first loading / unloading ports 110 and the plurality of second loading / unloading ports 120 are arranged in a one-to-one correspondence. The plurality of first side doors 200 are rotatable and disposed on the top of the container body 100, and the first side doors 200 can cover or open at least one first loading / unloading port 110. The plurality of second side doors 300 are rotatable and disposed on the top of the container body 100, and the second side doors 300 can cover or open at least one second loading / unloading port 120. Multiple transport pallets 700 are spaced apart along the length of the container 100 on the bottom wall 140 of the container 100, with one transport pallet 700 corresponding to each first loading / unloading port 110 and each second loading / unloading port 120. Each transport pallet 700 is fixed to the bottom wall 140 of the container 100 by bolts, allowing for easy disassembly.

[0064] Using the technical solution of this embodiment, the container includes: a container body 100, a plurality of first side doors 200, a plurality of second side doors 300, and a plurality of transport pallets 700. The plurality of first side doors 200 are rotatably disposed on the top of the container body 100, and each first side door 200 can cover or open at least one first loading / unloading port 110. The plurality of second side doors 300 are rotatably disposed on the top of the container body 100, and each second side door 300 can cover or open at least one second loading / unloading port 120. The plurality of transport pallets 700 are spaced apart along the length of the container body 100 on the bottom wall 140 of the container body 100, with one transport pallet 700 corresponding to each first loading / unloading port 110 and each second loading / unloading port 120. During loading operations, depending on the existing cargo inside the container, one of the plurality of first side doors 200 or the plurality of second side doors 300 is opened, and the cargo is placed from the first loading / unloading port 110 or the second loading / unloading port 120 onto the transport pallet 700 inside the container. During unloading operations, one of the multiple first side doors 200 or multiple second side doors 300 located where the goods to be unloaded are located is opened according to the position of the goods to be unloaded. The goods are then unloaded from the transport pallet 700 inside the container through the first loading / unloading port 110 or the second loading / unloading port 120. This allows one of the corresponding multiple first side doors 200 or multiple second side doors 300 to be opened as needed, eliminating the need to open all side doors during loading and unloading, thus improving efficiency, reducing the labor intensity of loading and unloading personnel, and shortening the loading and unloading time. Therefore, the technical solution of this embodiment effectively solves the problem of low efficiency in loading and unloading containers due to the need to open all side doors during loading and unloading.

[0065] It should be noted that the arrangement of multiple first side doors 200 and multiple second side doors 300 allows the container to be opened in sections without having to fully open both sides. The first side doors 200 and second side doors 300 are opened accordingly when loading or unloading specific goods, facilitating the loading and unloading operations of personnel. In this embodiment, both the first side doors 200 and the second side doors 300 are flat, avoiding the problems of bulkiness, weak rigidity and strength, and poor manufacturing flatness associated with "L"-shaped side doors in related technologies.

[0066] like Figures 1 to 4 As shown, the container also includes multiple dividers 130 disposed inside the container body 100, spaced apart along the length of the bottom wall 140 of the container body 100. The first side of each divider 130 forms multiple first loading / unloading openings 110 between the top and bottom wall 140 of the container body 100, and the second side of each divider 130 forms multiple second loading / unloading openings 120 between the top and bottom wall 140 of the container body 100. One divider 130 separates two adjacent transport pallets 700. The multiple dividers 130 can rationally arrange the internal space of the container body 100 to rationally arrange goods. Furthermore, the arrangement of the multiple dividers 130 can limit the movement of goods within the container along the length of the bottom wall 140 of the container body 100.

[0067] In this embodiment, a transport pallet 700 is manufactured according to the dimensions of a standardized pallet unit, and the distance between multiple dividers 130 along the length of the bottom wall 140 of the container body 100 is determined according to the dimensions of the transport pallet 700 for transferring the standardized pallet units. This allows the container to be adapted to standardized pallet units, improving the efficiency of loading and unloading goods and enhancing the container's applicability.

[0068] like Figures 1 to 4As shown, the multiple partition racks 130 include multiple first partition racks 131 and multiple second partition racks 132, which are arranged alternately along the length of the bottom wall 140 of the container body 100. Each first side door 200 covers or opens two corresponding first loading / unloading ports 110, and each second side door 300 covers or opens two corresponding second loading / unloading ports 120. In this way, when loading and unloading goods, the corresponding two first loading / unloading ports 110 can be opened by opening the corresponding first side door 200, or the corresponding two second loading / unloading ports 120 can be opened by opening the corresponding second side door 300, avoiding the need to open all side doors as in related technologies for container loading and unloading. This allows loading and unloading personnel to quickly locate the first loading / unloading port 110 or the second loading / unloading port 120 that needs to be loaded or unloaded, and also avoids the situation where loading and unloading personnel mistakenly pick up the wrong goods due to all side doors being open, thus improving the efficiency and accuracy of loading and unloading.

[0069] like Figures 6 to 8 As shown, a first elastic support member 510 is provided on the side of the box body 100 and on the first side of each second partition 132. The upper end of each first elastic support member 510 is hinged to the corresponding first side door 200, and the lower end of each first elastic support member 510 is hinged to the side of the box body 100 or the first side of the second partition 132. A second elastic support member 520 is provided on the side of the box body 100 and on the second side of each second partition 132. The upper end of each second elastic support member 520 is hinged to the corresponding second side door 300, and the lower end of each second elastic support member 520 is hinged to the side of the box body 100 or the second side of the second partition 132. The arrangement of the first elastic support member 510 and the second elastic support member 520 allows the first side door 200 and the second side door 300 to be opened without external force, without requiring external power, and without restricting the place of use. This avoids the need for external power or hydraulic stations to open side doors, as is the case with related technologies, which require power or hydraulic stations at the loading and unloading site, thus limiting the usability of the space.

[0070] In this embodiment, the first elastic support 510 and the second elastic support 520 are preferably air spring support rods, which are rod-shaped. The direction of the force output from the upper end of the air spring support rod is always away from the direction of extension of the lower end of the air spring support rod, and the direction of the force output from the lower end of the air spring support rod is always away from the direction of extension of the upper end of the air spring support rod. The air spring support rod is a telescopic rod with almost constant lift. The air spring support rod includes: a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, and a filling material of inert gas or an oil-gas mixture. The control elements inside and outside the pressure cylinder refer to controllable air springs and connectors, etc. The internal structure of the air spring support rod is a piston rod that can move linearly within a closed pressure cylinder cavity. The cavity of the pressure cylinder is filled with a liquid-gas two-phase mixture consisting of high-pressure gas and a liquid that can dissolve part of the high-pressure gas. The lifting force of the air spring support rod is generated by the high-pressure gas pushing the piston rod. The thrust is determined by the pressure of the high-pressure gas. The solubility of high-pressure gas in a liquid increases with increasing gas compression (this process is analogous to an air spring support rod working during the compression phase), and decreases with increasing gas expansion (this process is analogous to an air spring support rod working during the extension phase). The density of high-pressure gas in a sealed cylinder remains approximately constant, meaning the gas pressure is approximately constant. Depending on different characteristics and applications, it is also called a gas spring support rod, air spring support bar, pressure rod, or damper.

[0071] like Figures 6 to 8 As shown, the upper end of each first elastic support 510 is hinged to the corresponding first side door 200 via a first hinge pin 530, and the lower end of each first elastic support 510 is hinged to the side of the housing 100 or the first side of the corresponding second partition 132 via a second hinge pin 540. It should be noted that in this embodiment, both the first elastic support 510 and the first elastic support 510 are rod-shaped. The direction of the force output from the upper end of the first elastic support 510 always faces away from the extension direction of the lower end of the first elastic support 510. Furthermore, when the first side door 200 covers the first loading / unloading port 110, the first hinge pin 530 is closer to the center of the housing 100 than the second hinge pin 540. Thus, the direction of the force exerted by the upper end of the first elastic support 510 on the first hinge pin 530 of the first side door 200 is opposite to the direction of extension of the lower end of the first elastic support 510. That is, the component of the force exerted by the upper end of the first elastic support 510 on the first hinge pin 530 of the first side door 200 is directed towards the middle of the box 100 and towards the top of the box 100. The component of the force exerted by the first elastic support 510 on the first side door 200 is directed towards the middle of the box 100, so that the first side door 200 can be fixed and kept in the closed state when it covers the first loading and unloading port 110.

[0072] like Figures 4 to 8As shown, the upper end of each second elastic support 520 is hinged to the corresponding second side door 300 via a third hinge pin 550, and the lower end of each second elastic support 520 is hinged to the side of the housing 100 or the second side of the corresponding second partition 132 via a fourth hinge pin 560. When the second side door 300 covers the second loading / unloading port 120, the third hinge pin 550 is closer to the center of the housing 100 than the fourth hinge pin 560. The structure and working principle of the second elastic support 520 are the same as those of the first elastic support 510. In this way, the second elastic support 520 can be fixed and kept in the covered state when the second side door 300 covers the second loading / unloading port 120.

[0073] like Figures 6 to 8 As shown, the container also includes multiple auxiliary support frames 400 pivotally mounted on the sides of the container body 100 and on multiple second partition frames 132. The pivot axis of each auxiliary support frame 400 extends vertically, and each auxiliary support frame 400 has a retractable position inside the container body 100 and an auxiliary support position supported below the first side door 200. When the first side door 200 is opened, the auxiliary support frame 400 is adjusted to the auxiliary support position. When the first elastic support member 510 supports the first side door 200, the auxiliary support frame 400 can assist in supporting the first side door 200. Furthermore, when the first elastic support member 510 fails, the auxiliary support frame 400 can support the first side door 200 to protect loading and unloading personnel below the first side door 200 from being injured. In this embodiment, the auxiliary support frame 400 is positioned closer to the first loading / unloading port 110 than the first elastic support member 510 to protect the first elastic support member 510 from impact during loading and unloading, thereby improving the service life of the first elastic support member 510.

[0074] like Figures 6 to 8As shown, each auxiliary support frame 400 includes a pivot shaft 410 pivotally mounted on the side of the housing 100 or on the second partition frame 132, and a support frame 430 connected to the pivot shaft 410. The support frame 430 includes a first support rod 431 connected to the upper end of the pivot shaft 410, a second support rod 432 connected to the lower end of the pivot shaft 410, and a connecting rod 420 connecting the first support rod 431 and the second support rod 432. This improves the structural strength of the support frame 430 and enhances the stability of the auxiliary support frame 400 when supporting the first side door 200 or the second side door 300. The length of the first support rod 431 is greater than the length of the second support rod 432, making the structure of the auxiliary support frame 400 more compact while ensuring the structural strength of the support frame 430, thus facilitating loading and unloading operations by personnel at the first loading / unloading port 110 or the second loading / unloading port 120. In this embodiment, a handle is provided on the pivot shaft 410. The loading and unloading personnel operate the handle to drive the pivot shaft 410 to rotate the auxiliary support frame 400 to support the first side door 200 or the second side door 300. The operation is simple and safe. For each first loading and unloading port 110, two auxiliary support frames 400 are preferably provided; for each second loading and unloading port 120, two auxiliary support frames 400 are preferably provided.

[0075] like Figures 1 to 3 as well as Figures 6 to 8 As shown, the upper ends of multiple first side doors 200 are rotatably mounted on the top of the housing 100. The auxiliary support frame 400 includes multiple first pull members 440, one end of which is connected to the lower end of each first side door 200. Pulling one first pull member 440 causes the lower end of the first side door 200 to rotate, thus covering the two corresponding first loading / unloading ports 110. The upper ends of multiple second side doors 300 are rotatably mounted on the top of the housing 100. The auxiliary support frame 400 includes multiple second pull members 450, one end of which is connected to the lower end of each second side door 300. Pulling one second pull member 450 causes the lower end of the second side door 300 to rotate, thus covering the two corresponding second loading / unloading ports 120. In this embodiment, the first pulling member 440 and the second pulling member 450 are preferably ropes.

[0076] like Figures 20 to 27As shown, the transport pallet 700 of this embodiment includes a base 10 and a first pushing assembly 20. The upper surface of the base 10 is provided with a clearance opening 11 extending along its length direction. The upper surface of the base 10 has at least two placement stations 12, and the arrangement direction of the at least two placement stations 12 is the same as the extension direction of the clearance opening 11. The first pushing assembly 20 is disposed on the base 10. The first pushing assembly 20 includes a first pushing frame 21 and a driving member. The first pushing frame 21 is movably disposed along the length direction of the base 10 and has a first initial position located at the first end of the base 10 and a pushing position away from the first end of the base 10. The upper end of the first pushing frame 21 extends through the clearance opening 11 and forms a pushing part 211. The driving member is disposed at the second end of the base 10 and has a driving force input part 221 that cooperates with an external structure. The driving member can drive the first pushing frame 21 to switch from the first initial position to the pushing position.

[0077] Using the above-described technical solution, the transport pallet 700 includes a base 10 and a first pushing assembly 20. When unloading goods 70 using the transport pallet 700, an external tool, in conjunction with a drive force input unit 221, drives the first pushing frame 21 to move from an initial position at the first end of the base 10 along the length of the base 10 to a pushing position away from the first end of the base 10. During this process, the pushing part 211 of the first pushing frame 21, which protrudes through the clearance opening 11 on the upper surface of the base 10, moves from the first end of the base 10 toward the second end of the base 10, thereby moving the goods 70 on the placement station 12 toward the second end of the base 10 so that the forklift forks can lift the goods 70. Thus, the goods 70 can be unloaded from the transport pallet 700 by a forklift. When loading goods 70 using the transport pallet 700, the forklift pushes the goods 70 from the second end of the base 10 to the first end of the base 10, allowing goods 70 to be placed on at least two placement stations 12.

[0078] In this embodiment, the first pushing component 20 is disposed on the base 10, meaning that part of the main structure of the first pushing component 20 is located inside the base 10, and the pushing part 211 is located on the upper surface of the base 10.

[0079] It should be noted that the first pusher 21 has a push position away from the first end of the base 10, which means that the first pusher 21 is away from the first end of the base 10 relative to the first initial position.

[0080] like Figures 20 to 22As shown, the driving component includes a first driving frame 22 movable along the length of the base 10. The first driving frame 22 moves toward the first pushing frame 21 and has a second initial position located at the second end of the base 10 and a driving position away from the second end of the base 10. When the first driving frame 22 switches from the second initial position to the driving position, the first pushing frame 21 switches from the first initial position to the pushing position. Using the first driving frame 22, the first pushing frame 21 can be moved from the first initial position to the pushing position, which has the advantage of ease of operation.

[0081] In this embodiment, in order to facilitate the arrangement of the first push frame 21 and the first drive frame 22, the first drive frame 22 is located below the first push frame 21 in the vertical direction.

[0082] Specifically, a first limiting beam is provided at the first end of the base 10 to limit the first pushing frame 21. By providing the first limiting beam, the first pushing frame 21 can be limited from exceeding the first initial position. A second limiting beam is provided at the second end of the base 10 to limit the first driving frame 22. By providing the second limiting beam, the first driving frame 22 can be limited from exceeding the second initial position.

[0083] like Figure 21 and Figure 22 As shown, the first pushing assembly 20 also includes a transmission component 23, which includes a first roller 231 and a first transmission cable 232. The first roller 231 is rotatably mounted on the second end of the base 10. The first transmission cable 232 is wound around the outer periphery of the first roller 231. The first end of the first transmission cable 232 is connected to the first pushing frame 21 through a first connecting part 233, and the second end of the first transmission cable 232 is connected to the first drive frame 22 through a second connecting part 234. The first connecting part 233 is located above the second connecting part 234. Using the above-described transmission component 23, the first and second connecting parts are located on the upper and lower sides of the first roller 231 respectively, thereby enabling the first and second ends of the first transmission cable 232 to move towards each other. This allows the first drive frame 22 to drive the first pushing frame 21 from the first initial position to the pushing position, offering advantages such as simple structure and ease of installation.

[0084] In this embodiment, the first transmission cable 232 should have good rigidity in order to transmit force.

[0085] like Figures 20 to 22As shown, the transmission component 23 also includes a second roller 235 and a second transmission cable 236. The second roller 235 is rotatably disposed at the first end of the base 10. The second transmission cable 236 is wound around the outer periphery of the second roller 235. The first end of the second transmission cable 236 is connected to the first push frame 21 through a third connecting part 237. The second end of the second transmission cable 236 is connected to the first drive frame 22 through a fourth connecting part 238. The third connecting part 237 is located above the fourth connecting part 238.

[0086] In this embodiment, in order to ensure the smooth movement of the first pushing frame 21 and the first driving frame 22, transmission members 23 are provided on both sides of the first pushing assembly 20, and the first roller 231 and the second roller 235 are both located above the first driving frame 22 and on both sides of the first pushing frame 21.

[0087] Both the first drive frame 22 and the first push frame 21 are formed by welding steel pipes.

[0088] like Figure 20 and Figure 22 As shown, the first connecting part 233 includes a first hinge shaft 2331, a first hinge piece 2332, and a first hinge plate 2333. The first hinge piece 2332 is provided with a first hinge hole and is located on one side of the first pusher frame 21. The first hinge plate 2333 is provided with a second hinge hole and is located at the first end of the first transmission cable 232. The first hinge shaft 2331 passes through the first hinge hole and the second hinge hole. With the above structure, the first connecting part 233 can realize the hinge of the first transmission cable 232 and the first pusher frame 21 by using the first hinge shaft 2331. In this way, the hinge method of the first connecting part 233 can form a force buffer, so as not to cause the first pusher frame 21 to be suddenly subjected to force and cause damage.

[0089] In this embodiment, the first hinge piece 2332 and the first hinge plate 2333 are both connected to the corresponding components by welding.

[0090] Specifically, the second connecting part 234 includes a first connecting plate 2341, a first connecting nut 2342, and a first threaded section 2343. The first connecting plate 2341 has a first connecting hole and is connected to the first drive frame 22. The first threaded section 2343 is located at the second end of the first transmission cable 232 and passes through the first connecting hole. The threaded position of the first connecting nut 2342 is adjustablely connected to the first threaded section 2343. With the above-described structure, the length of the first threaded section 2343 extending out of the first connecting hole can be adjusted using the first connecting nut 2342, thereby adjusting the length of the first transmission cable 232. This prevents the first transmission cable 232 from elongating due to prolonged use and failing to transmit force, thus extending its service life.

[0091] In this embodiment, the first connecting plate 2341 is welded onto the first drive frame 22. To ensure smoother rotation of the first transmission cable 232, the first connecting portion 233 and the second connecting portion 234 are spaced apart along the length of the base 10.

[0092] like Figure 20 and Figure 21 As shown, the third connecting part 237 includes a second connecting plate, a second connecting nut, and a second threaded section. The second connecting plate is provided with a second connecting hole and is connected to the first pushing frame 21. The second threaded section is provided at the first end of the second transmission cable 236 and passes through the second connecting hole. The threaded position of the second connecting nut is adjustablely connected to the second threaded section. With the above-described structure, the length of the second threaded section extending out of the second connecting hole can be adjusted by using the second connecting nut, thereby adjusting the length of the second transmission cable 236. This prevents the second transmission cable 236 from elongating due to prolonged use and failing to transmit force, thus extending the service life of the second transmission cable 236.

[0093] In this embodiment, the second connecting plate is disposed on one side of the first pushing frame 21.

[0094] Specifically, the fourth connecting part 238 includes a second hinge shaft, a second hinge piece, and a second hinge plate. The second hinge piece has a third hinge hole and is connected to the first drive frame 22. The second hinge plate has a fourth hinge hole and is located at the second end of the second transmission cable 236. The second hinge shaft passes through the third hinge hole and the fourth hinge hole. With the above-described structure, the fourth connecting part 238 can achieve hinge connection between the second transmission cable 236 and the first drive frame 22 using the second hinge shaft. Furthermore, the hinge connection of the fourth connecting part 238 can generate a pulling force on the first drive frame 22, making the movement of the first drive frame 22 easier.

[0095] In this embodiment, by setting the first transmission cable 232 and the second transmission cable 236, the force between the first pushing frame 21 and the first driving frame 22 can be evenly distributed between the first transmission cable 232 and the second transmission cable 236, thereby making both transmission cables less prone to damage and extending their service life.

[0096] like Figure 20 , Figure 23 as well as Figure 27As shown, the transport pallet 700 also includes a first guide assembly 30 disposed between the base 10 and the first drive frame 22. The first guide assembly 30 includes a first guide wheel 31 and a first guide groove. The first guide wheel 31 is disposed in one of the base 10 and the first drive frame 22, and the first guide groove is disposed in the other of the base 10 and the first drive frame 22. By using the first guide assembly 30, the first drive frame 22 can be guided, so that the first drive frame 22 can move along the length direction of the base 10.

[0097] In this embodiment, first guide components 30 are provided on both sides of the first drive frame 22, which makes the movement of the first drive frame 22 more stable. First guide wheels 31 are provided on both sides of the first drive frame 22, and the base 10 is provided with first channel steel corresponding to the first guide wheels 31, forming first guide grooves.

[0098] Specifically, the transport pallet 700 further includes a second guide assembly 40 disposed between the base 10 and the first pusher frame 21. The second guide assembly 40 includes a second guide wheel 41 and a second guide groove 42. The second guide wheel 41 is disposed on one of the base 10 and the first pusher frame 21, and the second guide groove 42 is disposed on the other. By using the second guide assembly 40, the first pusher frame 21 can be guided, allowing the first pusher frame 21 to move along the length direction of the base 10.

[0099] In this embodiment, second guide components 40 are provided on both sides of the first push frame 21, which makes the movement of the first push frame 21 more stable. The second guide wheels 41 are provided on both sides of the first push frame, and the base 10 is provided with second channel steel corresponding to the second guide wheels 41, the second channel steel forming a second guide groove 42.

[0100] like Figure 21 and Figure 27 As shown, one end of the first drive frame 22 is provided with a drive groove 222 facing the second end of the base 10. The drive groove 222 extends along the width direction of the base 10 and forms a drive force input part 221. Using a drive groove 222 to form the drive force input part 221 has the advantages of simple structure and easy installation.

[0101] In this embodiment, the upper surface of the base 10 is provided with two placement stations 12. The first drive frame 22 is driven to move by the fork teeth of a forklift pushing the drive groove 222, which has the advantage of being easy to operate.

[0102] like Figure 20 and Figure 22As shown, the transport pallet 700 also includes a retractable reset member 50 extending along the length of the base 10. The two ends of the reset member 50 are connected to the first end of the base 10 and the first pusher frame 21, respectively. By using the reset member 50, the first pusher frame 21 can be moved to the pusher position and then automatically reset to the first initial position under the elastic force of the reset member 50, offering the advantage of a simple structure.

[0103] In this embodiment, the reset member 50 is an elastic rope, and the reset member 50 is disposed in the middle of the base 10 and the first push frame 21, so that the reset of the first push frame 21 is more stable.

[0104] like Figure 21 and Figure 26 As shown, the first moving frame 21 includes a frame body 212 and a moving beam 213 disposed on the upper surface of the frame body 212. The moving beam 213 is disposed at its end facing the first end of the base 10, and the moving beam 213 forms a moving part 211. The structure of the moving part 211 formed by the moving beam 213 has the advantages of simple structure and easy installation.

[0105] In this embodiment, in order to increase the contact area between the push beam 213 and the cargo 70, the push beam 213 extends along the width direction of the base 10.

[0106] like Figures 20 to 22 As shown, the transport pallet 700 also includes a second pushing assembly 60, which includes a second pushing frame 61 and a second drive frame 62. The second pushing frame 61 is movable along the length of the base 10 and is positioned above the first drive frame 22. The second drive frame 62 is movable along the length of the base 10 and is positioned below the first pushing frame 21. The second drive frame 62 can drive the second pushing frame 61 to move towards it. By using the second pushing assembly 60, the first pushing frame 21 can be used to move the goods 70 from the first end of the base 10 toward its second end, and the second pushing frame 61 can be used to move the goods 70 from the second end of the base 10 toward its first end. This allows both the first and second ends of the base 10 to exert a pushing effect on the goods 70, enhancing the adaptability of the transport pallet 700.

[0107] In this embodiment, the second push frame 61 and the second drive frame 62 are driven by a combination of a transmission cable and a roller. In order to facilitate the arrangement of the first transmission cable 232, a clearance hole is provided on the second push frame 61, and the first transmission cable 232 passes through the clearance hole and is wound around the first roller 231.

[0108] It should be noted that, in Figure 23In the middle, since the base 10 has a shielding plate on its side to shield and protect the first push frame 21 and the first drive frame 22, the shielding plate has an opening, through which the fork of the fork can contact the drive slot 222.

[0109] like Figure 11 As shown, this application also provides a method for loading and unloading cargo in a container, utilizing the aforementioned container to load and unload a first cargo and a second cargo. To provide multiple forms of cargo loading and unloading, achieve more flexible cargo loading and unloading, improve cargo loading and unloading efficiency, and shorten cargo loading and unloading time, the container cargo loading and unloading method includes a loading step and a unloading step.

[0110] The loading steps include: opening at least one of the multiple first side doors 200 of the container to avoid opening all side doors and improve loading efficiency; loading the first cargo onto the first placement station of the transport pallet 700 inside the container body 100; obtaining the first cargo information; transporting the first cargo from the first placement station of the transport pallet 700 to the second placement station of the transport pallet 700, wherein the first and second placement stations are arranged along the width direction of the container; loading the second cargo onto the first placement station of the transport pallet 700 inside the container body 100, allowing the first and second cargo to be loaded onto the second and first placement stations from the first side door 200 of the container, enabling cargo to be loaded from one side of the container; and obtaining the second cargo information.

[0111] It should be noted that the second partition rack 132 is equipped with a first card reader 610 corresponding to the first goods at the first placement station and a second card reader 620 corresponding to the second goods at the second placement station. The first goods have a first goods information card, and the second goods have a second goods information card. The first card reader 610 can acquire the first goods information from either the first or second goods information card, and the second card reader 620 can acquire the second goods information from either the second or first goods information card. Thus, based on the first and second goods information acquired by the first and second card readers 610 and 620, the location of the corresponding goods can be determined, allowing the corresponding first side door 200 or second side door 300 to be opened at the appropriate station to retrieve the specified goods.

[0112] The unloading steps include: opening the corresponding first side door 200 according to the second cargo information to avoid opening all side doors and improve unloading efficiency; unloading the second cargo from the first placement station; and transporting the first cargo from the second placement station of the transport pallet 700 to the first placement station of the transport pallet 700, whereby the first cargo is unloaded. In this way, the first and second cargoes can be unloaded from both the second and first placement stations through the first side door 200 of the container, allowing cargo to be unloaded from one side of the container. It should be noted that "corresponding" in "opening the corresponding first side door 200 according to the second cargo information" refers to the first side door 200 at the first loading / unloading port 110 of the transport pallet 700 when loading the second cargo.

[0113] like Figure 11 As shown, to avoid opening all side doors and improve loading efficiency, the loading steps also include: opening at least one of the multiple second side doors 300 of the container that correspond one-to-one with the multiple first side doors 200; loading the first cargo onto the second placement station of the transport pallet 700 inside the container body 100; obtaining the first cargo information on the first cargo; the transport pallet 700 transports the first cargo from the second placement station of the transport pallet 700 to the first placement station of the transport pallet 700, and loads the second cargo onto the second placement station of the transport pallet 700 inside the container body 100. In this way, the first cargo and the second cargo can be loaded onto the first placement station and the second placement station from the second side door 300 of the container, allowing cargo to be loaded from the other side of the container; and obtaining the second cargo information on the second cargo.

[0114] Furthermore, to avoid opening all side doors and improve unloading efficiency, the unloading steps also include: opening the corresponding second side door 300 according to the second cargo information; unloading the second cargo from the second placement station; and transporting the first cargo from the first placement station of the transport pallet 700 to the second placement station of the transport pallet 700, and unloading the first cargo from the second placement station. This allows the first and second cargoes to be unloaded from the first and second placement stations through the second side door 300 of the container, enabling the cargo to be unloaded from the other side of the container. It should be noted that "corresponding" in "opening the corresponding second side door 300 according to the second cargo information" refers to the second side door 300 at the second loading / unloading port 120 of the transport pallet 700 when loading the second cargo.

[0115] like Figures 9 to 11As shown, the container loading and unloading method described above includes a loading step. To prevent uneven loading of the container after loading, the loading step includes: opening all first side doors 200 and loading multiple goods onto one of the two placement positions of each transport pallet 700; detecting the weight of the goods on each transport pallet 700; and adjusting the position of the multiple goods on the corresponding transport pallet 700 according to the weight of the goods on each transport pallet 700. It should be noted that a weighing sensor 630 is provided on the bottom wall 140 of the container body 100, and the transport pallet 700 is fixed to the weighing sensor 630. In this embodiment, each transport pallet 700 is fixed to the bottom wall 140 of the container body 100 by four weighing sensors 630. The weighing sensor 630 detects the weight of the goods on each transport pallet 700. One of the two placement positions of each transport pallet 700 is the first placement position described above, and the other is the second placement position.

[0116] like Figure 11 As shown, to further prevent the container from being overloaded after loading, the step of adjusting the position of multiple goods on the corresponding transport pallet 700 according to the weight of the goods on each transport pallet 700 further includes: obtaining the center of gravity of all goods based on the weight of all goods; determining the difference between the center of gravity of all goods and the centerline of the container in the front-rear direction; and adjusting the position of multiple goods on the corresponding transport pallet 700 according to the difference, so that the difference is less than or equal to a preset threshold. It should be noted that the centerline extends in the front-rear direction. Preferably, the preset threshold is a difference of 100mm between the center of gravity of all goods and the centerline of the container in the front-rear direction.

[0117] In this embodiment, an insulating box is provided on the side wall of the housing 100, and the main unit is installed inside the insulating box. A battery pack, a weighing transmitter, a weighing terminal, a first card reader 610, a second card reader 620, and a door magnetic sensor are installed on the second partition frame 132. A data collector, a smoke sensor, and a temperature and humidity sensor are installed on the top of the housing 100. The weighing transmitter is connected to four weighing sensors 630 corresponding to one transport pallet 700 to aggregate the weight information of the goods on the transport pallet 700. The weighing terminal is connected to the first card reader 610, the second card reader 620, the door magnetic sensor, and the battery pack. The weighing terminal acquires data information from the first card reader 610, the second card reader 620, and the door magnetic sensor, and the battery pack powers the weighing terminal. The weighing terminal is also connected to a Bluetooth antenna, which transmits the received data information to the main unit located on the top of the housing 100. A data collector installed on top of the container 100 is connected to the main unit, smoke sensor, and temperature and humidity sensor, and is positioned adjacent to these sensors. The data collector collects signals from the smoke sensor and temperature and humidity sensor and sends the signals to the main unit. In this way, an intelligent monitoring system is set up to monitor temperature and humidity, smoke alarms, container positioning, pallet unit cargo positioning, cargo weighing, and door opening / closing within the container 100, providing real-time monitoring of cargo status. The monitoring data is transmitted to the server and monitoring platform in real time, giving loading and unloading personnel greater peace of mind.

[0118] In response to national policies promoting multimodal transport in recent years—namely, vigorously developing containerized multimodal transport, accelerating the containerization of railway freight and the rapid transport of scattered goods, promoting the use of standardized basic loading units such as pallet units and containers, and advancing the standardization of specialized multimodal transport equipment—and addressing the issue of the low proportion of railway multimodal and rapid transport for "white goods" (i.e., goods other than coal and coke), the inventor proposes a solution combining railway flatcars with transport pallets within containers. This involves combining two standardized, containerized transport units—transport pallets and containers—to meet the palletization needs of scattered goods multimodal transport, enabling "one-stop" transport, rapid loading and unloading, and immediate loading and unloading. The transport pallets use a first and second card reader to locate the goods, and intelligent equipment such as intelligent monitoring systems, along with logistics network technology, provide an equipment solution for intelligent and rapid logistics and the implementation of "freight-to-passenger" transport organization methods. This application is based on a container design using this solution, carrying standardized palletized goods and employing an intelligent monitoring system to achieve rapid loading, unloading, and transshipment of goods.

[0119] Applying the technical solution of this embodiment can reduce hoisting costs and achieve rapid loading, unloading, and transshipment of goods. Furthermore, the container in this application meets the strength and rigidity requirements for heavy-load lifting and other related container tests, enabling heavy-load lifting. This container meets the requirements for multimodal transport (road, rail, and water), allowing for door-to-door cargo handling without opening the container, reducing transshipment time and cargo damage. This container can load and unload all goods from any single platform, reducing the overall cost and time of container hoisting.

[0120] like Figures 12 to 19 As shown, the cargo loading and unloading method for containers according to this embodiment uses railway flatcars to transport goods, taking the loading and unloading of goods between multiple stations as an example:

[0121] Starting point: Empty containers are hoisted onto railway flatcars, awaiting marshalling (the sixteen placement positions for the containers are numbered, and numbered labels are affixed to the outside of the containers). Station A: The train stops at the platform on the left, the four first side doors 200 on the left side of the container are opened, and sixteen 1000kg cargo boxes 70 are loaded into the container by forklifts. The first side doors 200 are then closed, and the container is transported to the next station.

[0122] Station B: The train stops at the platform on the left. Open the first side door 200 at A3 and A4 on the left side of the container. Use a forklift to remove cargo 70 from A4. Use the forklift to operate the transport pallet 700 at A4 to pull cargo 70 from B4 to A4 and remove cargo 70 from B4. Load the two 800kg cargoes 70 into A4 and B4. Close the first side door 200 at A3 and A4. Similarly, open the first side door 200 at A7 and A8 on the left side of the container. Use a forklift to remove cargo 70 from A7. Use the forklift to operate the transport pallet 700 at A7 to pull cargo 70 from B7 to A7 and remove cargo 70 from B7. Load the two 800kg cargoes 70 into A7 and B7. Close the first side door at A7 and A8 and proceed to the next station.
