Description

Technical Field

[0001] This application relates to the field of logistics automation technology, and more specifically, to a container loading and unloading fixing device, a transport platform, and a container loading and unloading method. Background Technology

[0002] Pipeline rail transport systems are a novel mode of cargo transportation operating within enclosed pipelines, placing stringent requirements on the automation, lightweight design, and operational efficiency of the transport platform. Achieving fully automated loading and unloading of containers, reliable securing them during transport, and simultaneously meeting the demands for high efficiency, precise positioning, and high reliability on space- and weight-constrained vehicles like pipeline rail transport platforms presents a significant technological challenge in this field.

[0003] In existing technologies, some logistics automation solutions use devices such as conveyor belts that rely on frictional transmission to move goods. These solutions not only require high-power motors, resulting in high energy consumption and low efficiency, but also make it difficult to achieve precise positioning of goods due to their large inertia. Other solutions may use grippers (such as vacuum suction cups) to grab goods and pull them onto a separate conveyor for subsequent transfer. This method requires two separate systems for gripping and conveying, resulting in a complex overall structure, low functional integration, and difficulty in being suitable for compact and lightweight applications.

[0004] In addition, during transportation, additional complex locking mechanisms are usually required to secure the goods, which further leads to a bulky, heavy, and costly overall system structure.

[0005] Therefore, how to achieve automatic loading, unloading and reliable securing of containers on space-constrained vehicles has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0014] Optionally, in the above-mentioned container loading and unloading fixing device, the release mechanism includes a release telescopic member and a release member. The second end of the locking member has a release part that cooperates with the release member. The movable end of the release telescopic member is connected to the release member.

[0017] Optionally, in the above-mentioned container loading and unloading fixing device, the locking members are at least two that are spaced apart from each other, and adjacent two locking members are distributed in a cross pattern. The reset elastic member and the release mechanism are both adapted to the locking members.

[0018] Optionally, in the above-mentioned container loading and unloading fixing device, the towing assembly further includes a position detection element, which is used to monitor the position status of the container.

[0019] Optionally, in the above-mentioned container loading and unloading fixing device, the driving component includes a linear guide rail and a driving mechanism, the driving mechanism being able to drive the towing component to move along the linear guide rail.

[0020] Optionally, in the above-mentioned container loading and unloading fixing device, the driving mechanism includes a transmission screw, a drive motor and a transmission assembly. The transmission screw is arranged parallel to the linear guide rail. The dragging assembly has a transmission seat that cooperates with the transmission screw, and the output shaft of the drive motor is connected to one end of the transmission screw through the transmission assembly.

[0021] Optionally, the above-mentioned container loading and unloading fixing device further includes a locking component, which is used to lock the movement of the container.

[0022] Optionally, in the above-mentioned container loading and unloading fixing device, the locking assembly includes a locking telescopic member and an angle fixing seat. The movable end of the locking telescopic member is connected to the angle fixing seat, and the locking telescopic member can drive the angle fixing seat to lock or release the corner of the container.

[0023] Optionally, the above-mentioned container loading and unloading fixing device further includes a first guide roller assembly and a second guide roller assembly. The first guide roller assembly is used to guide the bottom of the container, and the second guide roller assembly is used to guide the sides of the container.

[0024] A transport platform includes a vehicle body and a container loading and unloading securing device as described in any of the preceding claims, the container loading and unloading securing device being located within the vehicle body.

[0025] A container loading and unloading method, applicable to the transport platform as described in any of the preceding claims, includes the following steps:

[0026] When the loading container is pushed into the target position of the loading and unloading fixing device by an external force, the locking member locks into the locking engagement part at the bottom of the container, and the driving assembly drives the towing assembly and the container to move to the preset loading position.

[0027] The unloading container is driven by the drive component to move the drag component and the container to a preset unloading position, and the release mechanism drives the locking member to disengage from the locking engagement part.

[0028] The container loading and unloading fixing device provided in this application allows the locking component to lock the container's locking engagement part by applying the elastic force of the resetting elastic element of the drag assembly during container loading. Simultaneously, the drag assembly is driven by the drive assembly to move along a preset path, thereby moving the container to a preset loading position. When unloading the container, the drag assembly is driven by the drive assembly to move along a preset path to a preset unloading position, and the locking component is disengaged from the locking engagement part of the container by the release mechanism. As can be seen from the above example, the container loading and unloading fixing device provided in this application achieves closed-loop precise control and efficient movement of the container position by driving the drag assembly with the drive assembly, overcoming the problems of inaccurate positioning and low efficiency caused by slippage and inertia in traditional friction conveyors. Furthermore, by integrating the locking component, the resetting elastic element for automatic reset, and the release mechanism for active disengagement onto the drag assembly and cooperating with the drive assembly, the same device can perform both loading and unloading actions and serve as a fixing device during transportation, meeting the application requirements of lightweight and compact design. In addition, automatic locking during loading is achieved through the reset elastic element, and reliable release is achieved through the release mechanism, thus enabling fully automatic unmanned operation under various working conditions such as loading, unloading on the same side, and unloading on opposite sides, making it more adaptable.

Detailed Implementation

[0042] The core of this application is to provide a container loading and unloading and securing device to achieve automatic loading, unloading and reliable securing of containers on space-constrained vehicles.

[0043] Another core aspect of this application is to provide a transport platform having the aforementioned container loading and unloading fixing device.

[0044] Another core aspect of this application is to provide a container loading and unloading method applicable to the aforementioned transport platform.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In rail transport systems, the space and weight constraints of the transport platform impose stringent requirements on the loading, unloading, and securing of containers. Existing technologies that rely on friction-driven transmission require high-power motors, leading to increased energy consumption and reduced efficiency. Furthermore, the high inertia of motion makes it difficult to achieve precise positioning of the containers. In addition, solutions using grippers and independent conveyors require two systems to work together, resulting in complex structures and low functional integration, making them unsuitable for compact and lightweight applications. The additional locking mechanism further increases the structural complexity and weight of the system, affecting the stability of automation and operational efficiency.

[0047] Therefore, such as Figure 1 As shown in the figure, this application discloses a container loading and unloading fixing device 100, including a dragging assembly 10 and a driving assembly 20. By driving the dragging assembly 10 through the driving assembly 20, closed-loop precise control and efficient movement of the container 60's position are achieved, overcoming the problems of inaccurate positioning and low efficiency caused by slippage and inertia in traditional friction conveyor belts. Simultaneously, the locking element 11, the reset elastic element 12 for automatic reset, and the release mechanism 13 for active disengagement are all integrated onto the dragging assembly 10 and cooperate with the driving assembly 20, enabling the same device to perform loading and unloading actions as well as serve as a fixing device during transportation, meeting the application requirements of lightweight and compact design. Furthermore, the reset elastic element 12 achieves automatic locking during loading, and the release mechanism 13 enables reliable release, thereby achieving fully automated unmanned operation under various working conditions such as loading, same-side unloading, and opposite-side unloading, making it more adaptable.

[0048] The following will combine Figures 1 to 10 The container loading and unloading fixing device 100 disclosed in the embodiments of this application will be explained and described in detail.

[0049] like Figure 1 As shown, the dragging component 10 serves as the core execution unit for the movement and positioning of the container 60. It can be a linear moving platform with a fixed gripping mechanism, or the dragging component 10 can be a simple slider with components that can be connected to the container 60 and move in a straight line or curve through an external power source.

[0050] like Figures 1 to 3 As shown, the dragging assembly 10 may include a locking member 11, a reset elastic member 12, and a release mechanism 13. The locking member 11, as a component directly mechanically connected to the container 60, can be a simple pin, hook, or clamp. Simultaneously, the bottom of the container 60 may be provided with a locking engagement part 61, which can be a hole, protrusion, or groove that mates with the locking member 11. This allows the locking member 11 to engage with the locking engagement part 61 at the bottom of the container 60 after the container 60 has moved into position, thereby locking and securing the container 60. For example, the locking member 11 can be a retractable pin, and the locking engagement part 61 can be a hole that mates with the pin. When the pin extends, it inserts into the hole on the container 60, thus achieving locking. Meanwhile, one end of the reset elastic element 12 can be fixed, and the other end of the reset elastic element 12 can abut against the locking element 11 to apply an elastic force to the locking element 11. This allows the locking element 11 to maintain a locked state that can lock the locking engagement part 61 when no external force is applied. The reset elastic element 12 can be a compression spring, a tension spring, or a torsion spring. The release mechanism 13 can drive the locking element 11 to disengage from the locking engagement part 61. The release mechanism 13 can be a push rod, a cable mechanism, or a cam mechanism. For example, the release mechanism 13 can be an electric push rod. When unloading the container 60, the electric push rod can extend and push the locking element 11 to disengage it from the locking engagement part 61.

[0051] like Figure 1 and Figure 4 As shown, the drive assembly 20 can be connected to the towing assembly 10 for transmission, so that the drive assembly 20 can drive the towing assembly 10 to reciprocate along a preset path. The drive assembly 20, as the power provider for the towing assembly 10, can be a hydraulic cylinder, pneumatic cylinder, chain drive system, or rack and pinion system, etc. For example, the drive assembly 20 can be a hydraulic cylinder, with its piston rod directly or indirectly connected to the towing assembly 10, driving the towing assembly 10 to move through hydraulic pressure. Meanwhile, the preset path can be a straight line, a curve, or a composite path. For example, the drive assembly 20 can drive the towing assembly 10 to perform linear reciprocating motion on a fixed guide rail, thereby achieving precise loading, unloading, and positioning of the container 60 on the transport platform 200.

[0052] like Figure 6 and Figure 7As shown, when loading container 60, container 60 is first pushed or pulled towards the target position on the transport platform 200 by an external pushing or pulling force (generated by other conveying systems or manually). When container 60 reaches the target position, the locking engagement part 61 at its bottom aligns with the locking member 11 on the dragging assembly 10 of the container loading and unloading fixing device 100. At this time, the elastic force applied by the reset elastic member 12 to the locking member 11 causes the locking member 11 to automatically engage with the locking engagement part 61 and lock, thereby firmly fixing container 60. Then, as... Figure 8 As shown, the drive assembly 20 can be activated. Through a transmission connection with the towing assembly 10, the drive assembly 20 can drive the towing assembly 10 along a preset path, such as a straight path along the width direction of the transport platform 200. Since the container 60 is locked by the locking member 11, it will move together with the towing assembly 10 until it reaches the preset loading position, i.e., the final fixed position of the container 60 on the transport platform 200. During this process, the movement of the towing assembly 10 ensures the precise positioning of the container 60.

[0053] like Figure 9 As shown, when unloading the container 60, the drive assembly 20 can first be reactivated, driving the drag assembly 10 and the locked container 60 to move in the opposite or same direction along a preset path until a preset unloading position is reached. The preset unloading position is a location convenient for the container 60 to be received by an external system or manually removed. Specifically, the preset unloading position can be on one side of the transport platform 200 and in the same direction as the loading direction of the container 60, or on the other side of the transport platform 200 and opposite to the loading direction of the container 60. Then, the release mechanism 13 can be activated, driving the locking member 11 to disengage from the locking engagement part 61 of the container 60. For example, the release mechanism 13 can push or pull the locking member 11 to release it from the locking engagement part 61. Once the locking member 11 disengages, the container 60 is no longer secured by the drag assembly 10, and can thus be removed from the transport platform 200 by external force.

[0054] In the above embodiments, the dragging component 10 and the driving component 20 work together to achieve automatic locking, precise movement, reliable fixation, and automatic release of the container 60. The cooperation between the dragging component 10 and the driving component 20 ensures efficient reciprocating motion and precise positioning of the container 60 on the transport platform, while the cooperation between the locking element 11 and the reset elastic element 12 ensures reliable fixation of the container 60 during transportation. Simultaneously, the release mechanism 13 provides a convenient unlocking method, enabling automated unloading of the container 60.

[0055] The container loading and unloading fixing device 100 disclosed in this application can, when loading the container 60, apply the elastic force of the locking member 11 to the reset elastic member 12 of the dragging assembly 10, so that the locking member 11 can lock the locking engagement part 61 of the container 60. At the same time, the dragging assembly 10 can be driven by the driving assembly 20 to move along a preset path, thereby moving the container 60 to a preset loading position. When unloading the container 60, the dragging assembly 10 can be driven by the driving assembly 20 to move along a preset path to a preset unloading position. At the same time, the locking member 11 can be driven to disengage from the locking engagement part 61 of the container 60 by the release mechanism 13.

[0056] The container loading and unloading fixing device 100 disclosed in this application realizes closed-loop precise control and efficient movement of the container 60 position by driving the dragging component 10 through the driving component 20. This overcomes the problems of inaccurate positioning and low efficiency caused by slippage and inertia in traditional friction conveyor belts. Simultaneously, the locking component 11, the reset elastic component 12 for automatic reset, and the release mechanism 13 for active disengagement are all integrated onto the dragging component 10 and cooperate with the driving component 20. This allows the same device to perform loading and unloading actions as well as act as a fixing device during transportation, meeting the application requirements of lightweight and compact design. Furthermore, the reset elastic component 12 achieves automatic locking during loading, and the release mechanism 13 enables reliable release, thereby achieving fully automated unmanned operation under various working conditions such as loading, same-side unloading, and opposite-side unloading, making it more adaptable.

[0057] In some embodiments, such as Figures 1 to 3As shown, the drag assembly 10 may further include a drag base 14, and a locking member 11 is rotatably mounted on the drag base 14. The first end of the locking member 11 is provided with a hook portion 111, which can engage with the locking engagement portion 61. One end of the reset elastic member 12 is connected to the second end of the locking member 11, and the other end of the reset elastic member 12 is connected to the drag base 14, so that an elastic force can be applied to the locking member 11 through the reset elastic member 12. Specifically, the drag base 14, as the structural foundation component of the drag assembly 10, can support and fix other components in the drag assembly 10, and it can be made of a metal plate, profile, or casting with a certain strength and rigidity. The locking member 11 is rotatably mounted on the towing base 14, allowing it to rotate around an axis. When subjected to external force, the locking member 11 can change its position and orientation by rotation, thereby locking or disengaging it from the locking engagement part 61 of the container 60. Simultaneously, the hook part 111 can be located at the first end of the locking member 11, engaging with the locking engagement part 61 of the container 60 to ensure the container 60 is securely fixed during towing. One end of the reset elastic member 12 is connected to the second end of the locking member 11, which is the opposite end to the hook part 111. The other end of the reset elastic member 12 is fixedly connected to the towing base 14, allowing it to generate an elastic restoring force when stretched. This force is transmitted to the locking member 11 through its connection to the second end of the locking member 11, driving the locking member 11 to rotate and maintain it in the locked position.

[0058] In some embodiments, such as Figures 1 to 3As shown, the drag seat 14 can be made of high-strength steel or aluminum alloy profile, and a hinge seat can be provided on the top of the drag seat 14 so that the locking member 11 can be rotatably mounted on the hinge seat at the middle position through the rotating pin 113. That is, a shaft hole can be opened at the middle position of the locking member 11 so that the rotating pin 113 can rotatably pass through the shaft hole and be fixed on the hinge seat. A bearing or bushing can be provided at the shaft hole to reduce rotational friction. The locking member 11 can be an L-shaped or hooked metal component, and the first end of the locking member 11 can form a hook portion 111 to engage with the locking engagement portion 61 at the bottom of the container 60. At the same time, the reset elastic member 12 can be a tension spring, and one end of the tension spring can be connected to the second end of the locking member 11, and the other end of the tension spring is connected to the corresponding fixing point on the drag seat 14. When the container 60 is pushed or pulled from the first end to the second end of the locking member 11 by an external force, the locking member 11 will rotate around the rotating pin 113 as the container 60 moves. That is, the first end of the locking member 11 gradually moves downward under the pressure of the locking engagement part 61 of the container 60, while the second end of the locking member 11 moves upward. At this time, the tension spring at the second end of the locking member 11 is stretched until the hook part 111 at the first end of the locking member 11 hooks the locking engagement part 61. The tension spring can return to its initial state without external force, and thus, under the restoring force of the tension spring, the locking member 11 will quickly lock the locking engagement part 61. It should be noted that the reset elastic member 12 can also be a torsion spring, and the torsion spring can be sleeved on the rotating pin 113 of the locking member 11. The two ends of the torsion spring can respectively abut against the locking member 11 and the drag seat 14 to provide rotational reset force.

[0059] In some embodiments, such as Figure 3 As shown, to ensure the smooth movement of the locking engagement portion 61 of the container 60 from the first end to the second end of the locking member 11, a guide surface 1111 that can cooperate with the locking engagement portion 61 can be provided on the side of the hook portion 111 away from the hook groove, so as to ensure the smooth movement of the locking engagement portion 61. Specifically, the guide surface 1111 can be an inclined surface that gradually slopes from the top surface of the hook portion 111 to the bottom surface, that is, the cross-sectional area of ​​the top end of the hook portion 111 gradually increases towards the bottom end of the hook portion 111. At the same time, the locking engagement portion 61 can adopt a rectangular protrusion structure, and an arc chamfer can be provided at the edge of the locking engagement portion 61, so that when the locking engagement portion 61 of the container 60 contacts the hook portion 111, it can move smoothly, thereby ensuring the smooth movement of the locking engagement portion 61 of the container 60 from the first end to the second end of the locking member 11, and thus improving the stability of the locking member 11 locking the locking engagement portion 61 of the container 60.

[0060] In some embodiments, such as Figures 1 to 3As shown, the release mechanism 13 may include a release telescopic member 131 and a release member 132. The second end of the locking member 11 may have a release portion 112 that cooperates with the release member 132. The fixed end of the release telescopic member 131 may be mounted on a vertical support column extending outward from the drag seat 14, and the movable end of the release telescopic member 131 is connected to the release member 132. The release telescopic member 131 may drive the release member 132 to push the release portion 112 of the locking member 11, so that the locking member 11 may rotate around its rotation axis, i.e., the rotating pin 113, and disengage from the locking engagement portion 61. Specifically, the fixed end of the release telescopic member 131 can be installed on the vertical support column extending outward from the drag seat 14 using fasteners such as bolts, and the movable end of the release telescopic member 131 can be connected and fixed to the release member 132 using fasteners such as bolts, to ensure that the movement of the release telescopic member 131 can be directly transmitted to the release member 132, thereby driving the release member 132 to move. The release telescopic member 131 can be a pneumatic telescopic rod, a hydraulic telescopic rod, or an electric telescopic rod, etc. The release member 132, as an intermediate transmission component, can convert the telescopic movement of the release telescopic member 131 into a pushing action on the release part 112 of the locking member 11. The release member 132 can be a push rod, a fork, a connecting rod, or a block with a specific shape, so that it can effectively cooperate with the release part 112 and transmit force to the locking member 11. The release part 112, which is located at the second end of the locking member 11 away from the hook part 111, serves as the area on the locking member 11 that makes mechanical contact and transmits force with the release member 132. It can be a protruding structure, a pin, or a roller so that when the release member 132 is in action, it can generate a rotational torque that rotates around the rotating pin 113.

[0061] In some embodiments, the release telescopic member 131 may be an electric telescopic rod, which may contain a motor and a lead screw mechanism to precisely control the extension and retraction stroke of the telescopic rod. The movable end of the electric telescopic rod, i.e., the extended portion of the telescopic rod, can be connected to one end of the release member 132 via fasteners such as bolts. The release member 132 may be an L-shaped lever, with its short arm end connected to the movable end of the electric telescopic rod and its long arm end forming a push block. Simultaneously, the release portion 112 at the second end of the locking member 11 may have a cylindrical structure and can contact the push block of the L-shaped lever. When the electric telescopic rod extends, the push block of the L-shaped lever pushes the release portion 112 of the locking member 11, causing the locking member 11 to rotate counterclockwise around its rotating pin 113, thereby causing the hook portion 111 to move downwards and disengage from the locking engagement portion 61. Conversely, when the electric telescopic rod retracts, the elastic force of the reset elastic member 12 causes the locking member 11 to quickly reset.

[0062] In some embodiments, such as Figures 1 to 3As shown, the release part 112 may include a rolling element 1121, and the release element 132 has a guide slope 1321 that can cooperate with the rolling element 1121, so that the release element 132 can push the rolling element 1121 through the guide slope 1321. Specifically, the rolling element 1121, as a component capable of rolling motion, can reduce the friction between the release element 132 and the release part 112, ensuring the stability of the release extension element 131 pushing the release part 112 through the release element 132. The rolling element 1121 may be a roller rotatably mounted on the cylindrical release part 112, and its material may be a high-strength wear-resistant material, such as alloy steel, engineering plastics, or ceramics, to ensure its stability and durability in long-term use. The surface of the rolling element 1121 may also be hardened or coated with a friction-reducing coating. Furthermore, the rolling element 1121 may also be a protruding structure integrated into the rotatable release part 112, and the protruding structure may have an arc-shaped or spherical surface to facilitate rolling contact with the guide slope 1321. The guide ramp 1321, as a surface with a certain inclination angle on the release member 132, can cooperate with the rolling member 1121 to convert the linear motion of the release telescopic member 131 into a rotational pushing force on the locking member 11. The guide ramp 1321 can be a straight ramp, an arc ramp, or a composite ramp. Its inclination angle can be determined according to the required pushing force and the rotational stroke of the locking member 11 to better guide the movement trajectory of the rolling member 1121, ensuring effective force transmission and precise rotation of the locking member 11.

[0063] In some embodiments, the release part 112 may employ an integrated roller bearing as the rolling element 1121, with the axis of the roller bearing parallel to the rotation axis of the locking element 11. Simultaneously, a linear guide ramp that contacts the roller bearing may be provided on the release part 132. When the release telescopic element 131 extends, it can drive the guide ramp 1321 of the release part 132 to smoothly push the roller bearing, and the roller bearing rolls on the guide ramp 1321, thereby converting the linear motion of the release part 132 into a rotational torque on the locking element 11, causing the locking element 11 to rotate around its rotating pin 113, thus disengaging from the locking engagement part 61.

[0064] In some embodiments, such as Figure 1 and Figure 2As shown, the release mechanism 13 may further include a slide rail 133 and a slide block 134. The slide rail 133 may be mounted on the drag seat 14, and the slide block 134 may be mounted on the release component 132, while the slide block 134 can slide on the slide rail 133. Specifically, the slide rail 133 can be fixed to the drag seat 14 by bolts, riveting, welding, or integral molding to provide a stable reference for the movement of the slide block 134. The slide rail 133 may be a V-groove guide rail, providing guidance through its V-shaped cross-section and matching slide block 134; the slide rail 133 may also be a dovetail groove guide rail, providing high-rigidity guidance through its dovetail cross-section and matching slide block 134. The slide block 134 can be connected to the release member 132 by fasteners such as bolts or by an integrated design, ensuring that there is sufficient rigidity and stability between the two to transmit the force of the release telescopic member 131 and precisely drive the release member 132. The slide block 134 can slide along the slide rail 133, so that the release member 132 can move stably in a straight line. At the same time, the movement of the release member 132 can be precisely guided and supported by the slide block 134.

[0065] In some embodiments, such as Figure 1 and Figure 2 As shown, at least two locking members 11 can be arranged at intervals, and adjacent locking members 11 are distributed in a cross pattern. That is, two, three or more locking members 11 can be arranged at intervals, and adjacent locking members 11 are distributed in a cross pattern. At the same time, the reset elastic member 12 and the release mechanism 13 can both be adapted to the locking members 11, that is, each locking member 11 corresponds to one reset elastic member 12 and one release mechanism 13. Thus, the container 60 can be fixed by multiple independent locking units to maximize the contact area and coverage of the locking member 11 and the locking mating part 61 of the container 60, effectively preventing the container 60 from rotating or deflecting during loading and unloading, and further enhancing the fixing effect and stability.

[0066] In some embodiments, such as Figure 1 and Figure 2As shown, two locking members 11 can be arranged at intervals, with adjacent locking members 11 arranged in a crisscross pattern, meaning the hook portions 111 of the two locking members 11 are located on opposite sides. For ease of understanding, the two locking members 11 are defined as the first locking member and the second locking member. Specifically, the hook portion 111 at the first end of the first locking member is located on the side where the second end of the second locking member is located, and the hook portion 111 at the first end of the second locking member is located on the side where the second end of the first locking member is located. When the container 60 is pushed or pulled from the first end to the second end of the first locking member by an external force, the first locking member will rotate around the rotating pin 113 as the container 60 moves. That is, the first end of the first locking member gradually moves downward under the pressure of the locking engagement part 61 of the container 60, while the second end of the first locking member moves upward. At this time, the reset elastic member 12 of the second end of the first locking member is stretched until the hook part 111 of the first end of the first locking member can hook one side of the locking engagement part 61, and the hook part 111 of the first end of the second locking member can hook the other side of the locking engagement part 61. The reset elastic member 12 of the first locking member can return to its initial state without the action of external force. Thus, under the action of the restoring force of the reset elastic member 12, the first locking member will quickly lock the locking engagement part 61. Of course, the container 60 can also be pushed or pulled from the first end to the second end of the second locking member by an external force. For specific implementation methods, please refer to the above embodiments, which will not be repeated here.

[0067] In the above embodiments, by employing multiple locking elements 11 spaced apart and arranged in a crisscross pattern, the container 60 can be provided with multi-point, more uniform locking support. This enhances the overall stability of the container 60 during loading and unloading, effectively avoiding problems such as shaking, tilting, or uneven force distribution that may occur with single-point locking, thus significantly improving the fixing reliability of the container 60. Simultaneously, each locking element 11 is equipped with a reset elastic element 12 and a release mechanism 13, ensuring that each locking point can independently and reliably perform locking and releasing operations, further improving the safety, reliability, and efficiency of loading and unloading operations.

[0068] It should be noted that the locking engagement part 61 can also be two parts spaced apart along the moving direction of the container 60, so that the container 60 can be moved from different directions to the pre-loading position of the transport platform 200, which improves the convenience and flexibility of the container 60's movement.

[0069] In some embodiments, such as Figure 3As shown, the dragging assembly 10 may also include a position detection element 15, which monitors the position status of the container 60 and feeds it back to the control system. Specifically, the position detection element 15 provides real-time position data of the container 60, enabling the control system to perform precise control and judgment. The position detection element 15 may be a limit switch, and the limit switch may be adapted to the locking member 11. That is, each locking member 11 may have a corresponding limit switch, and the limit switch may be installed on the dragging base 14 and located below the corresponding locking member 11. This allows the limit switch to monitor the movement of the corresponding rotating locking member 11 and feed back a signal to the control system that the container 60 has been loaded, thereby enabling the control system to issue a movement command to the drive assembly 20. Alternatively, the position detection element 15 may also be a photoelectric sensor, which detects changes in the light signal of the edge or specific marker of the container 60 to determine whether it has reached a preset position and feeds it back to the control system.

[0070] In some embodiments, the position detection element 15 may employ two photoelectric sensors mounted on the towing bracket 14, with the two photoelectric sensors located at the starting point of the container 60 entering the locking area and the ending point after the container 60 is fully in place, respectively. When the container 60 is pushed in, the first photoelectric sensor is triggered, indicating that the container 60 has entered the detection range; when the container 60 continues to move and triggers the second photoelectric sensor, it indicates that the container 60 has reached the preset locking position and locked. At this time, the control system can issue a command to allow the drive assembly 20 to drive the towing assembly 10 to move. Of course, during the process of the towing assembly 10 driving the container 60 to move, additional photoelectric sensors or proximity switches may also be provided on the container loading and unloading fixing device 100 to monitor whether the container 60 moves correctly along the preset path. Once the container 60 deviates, causing the corresponding sensor to not be triggered, the control system can issue an alarm or stop the operation of the drive assembly 20.

[0071] In some embodiments, such as Figure 1 and Figure 4As shown, the drive assembly 20 may include a linear guide rail 21 and a drive mechanism 22, and the drive mechanism 22 can drive the drag assembly 10 to move along the linear guide rail 21. Specifically, two linear guide rails 21 may be arranged in parallel, and the two linear guide rails 21 can be fixed to the transport platform 200 by a base plate 211. At the same time, guide sliders 141 adapted to the linear guide rail 21 are fixed on both sides of the bottom of the drag seat 14 of the drag assembly 10 by fasteners such as bolts or integral forming, so that the guide sliders 141 at the bottom of the drag seat 14 of the drag assembly 10 can slide along the linear guide rail 21 under the drive action of the drive mechanism 22, thereby ensuring that the drag assembly 10 can drive the container 60 on it to move stably along a straight line to the transport platform 200. Among them, the linear guide rail 21 may adopt a dovetail groove structure, and the guide sliders 141 can be adapted to the linear guide rail 21 to achieve high rigidity and high precision linear guidance through the precisely machined dovetail cross section. Of course, the linear guide 21 can also adopt a T-shaped structure, a C-shaped structure, etc. Meanwhile, the drive mechanism 22 can adopt a gear and rack mechanism, in which the motor drives the gear to rotate, and the gear meshes with the rack fixed next to the linear guide 21, thereby driving the towing assembly 10 to move; or, the drive mechanism 22 can also adopt a hydraulic or pneumatic cylinder, which directly drives the towing assembly 10 to move along the linear guide 21 by hydraulic or pneumatic thrust; of course, the drive mechanism 22 can also adopt a synchronous belt drive mechanism, in which the motor drives the synchronous belt, and the synchronous belt is fixed to the connecting parts on the towing assembly 10, thereby driving the towing assembly 10 to move.

[0072] In some embodiments, such as Figure 1 and Figure 4 As shown, the drive mechanism 22 may include a transmission screw 221, a drive motor 222, and a transmission assembly. The transmission screw 221 may be arranged parallel to the linear guide rail 21. The dragging assembly 10 has a transmission seat 23 that cooperates with the transmission screw 221. The output shaft of the drive motor 222 can be connected to one end of the transmission screw 221 through the transmission assembly, so that the drive motor 222 drives the transmission screw 221 to rotate, thereby moving the dragging assembly 10 on the transmission seat 23. Specifically, both ends of the transmission screw 221 can be mounted on the transport platform 200 or the base plate 211 respectively through screw seats 2211 with bearings. The transmission seat 23 can be a transmission nut fixed to the bottom of the dragging seat 14, and the transmission nut is threadedly engaged with the transmission screw 221. In addition, the drive motor 222 can be mounted on the transport platform 200 or the base plate 211 via the motor mount 2221. The drive motor 222 can be a servo motor with a brake and an encoder. At the same time, the output shaft of the drive motor 222 can transmit its torque to the transmission screw 221 via a synchronous belt transmission assembly or a gear transmission assembly to drive the transmission screw 221 to rotate, thereby driving the towing assembly 10 fixed with the transmission nut to move.

[0073] In some embodiments, such as Figure 4 As shown, the transmission assembly may include a transmission belt 223 and a synchronous pulley 224. The synchronous pulley 224 can be connected to the output shaft of the drive motor 222 and one end of the transmission screw 221 respectively. For example, the synchronous pulley 224 can be fixed to the output shaft of the drive motor 222 and one end of the transmission screw 221 by spline or directly. At the same time, the transmission belt 223 can be wrapped around the synchronous pulley 224 at one end of the output shaft of the drive motor 222 and the transmission screw 221 respectively, so as to transmit the torque output by the output shaft of the drive motor 222 to the transmission screw 221 through the transmission belt 223, thereby driving the transmission screw 221 to rotate, and thus driving the dragging assembly 10 fixed with the transmission nut to move.

[0074] In the above embodiments, the drive mechanism 22 employs a combination of a transmission screw 221, a drive motor 222, and a transmission belt 223, supplemented by the precise cooperation of the transmission seat 23 and the synchronous pulley 224, constructing a highly efficient and stable linear drive system. This ensures that the towing assembly 10 performs high-precision, highly repeatable reciprocating motion on the linear guide rail 21, significantly improving the positioning accuracy and operational stability of the container 60 during loading and unloading. Simultaneously, the transmission belt 223 ensures the synchronization of power transmission, preventing slippage, while the screw drive provides precise linear displacement, effectively addressing the shortcomings of traditional drive methods in terms of precision and stability, thereby improving the reliability and working efficiency of the entire container loading and unloading fixing device 100.

[0075] In some embodiments, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the container loading and unloading fixing device 100 may further include a locking assembly 30. The locking assembly 30 secures the container 60, preventing displacement. The locking assembly 30 may employ a mechanical clamping mechanism, applying pressure or forming a physical barrier to secure the container 60; alternatively, the locking assembly 30 may employ a pin or wedge system, inserting into specific structures of the container 60, such as corner pieces or side holes, to restrict its movement and ensure the stability of the transport platform 200 during container 60 transport.

[0076] In some embodiments, such as Figure 1As shown, the locking assembly 30 may include a locking telescopic member 31 and an angled fixing seat 32. The fixed end of the locking telescopic member 31 can be fixed to the transport platform 200, and the movable end of the locking telescopic member 31 can be connected to the angled fixing seat 32, so that the telescopic movement of the locking telescopic member 31 drives the angled fixing seat 32 to lock or release the corner of the container 60. The locking telescopic member 31 may be a pneumatic telescopic rod, a hydraulic telescopic rod, or an electric telescopic rod, etc., and the angled fixing seat 32 may have an L-shaped structure to match the corner structure of the container 60, thereby achieving effective fixation of the container 60. The movable end of the locking telescopic member 31 can be connected to the angled fixing seat 32 by bolts or other fasteners or by welding, ensuring that the telescopic movement of the locking telescopic member 31 can be directly transmitted to the angled fixing seat 32, enabling it to lock or release the corner of the container 60.

[0077] In some embodiments, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, at least two locking components 30 can be used, i.e., two, three, four, or more locking components 30 can be used. Locking components 30 can be respectively provided at the front and rear ends after the container 60 is loaded into position, so that the front and rear locking components 30 can extend out of the angled fixing seats 32, thereby locking the corners of the front and rear ends of the container 60. Thus, multiple locking components 30 can achieve multi-point fixation after the container 60 is loaded into position, ensuring the reliability of the container 60 loading, improving the stability of the transport platform 200 in transporting the container 60, and reducing the risk of the container 60 moving after the failure of the towing component 10 and the drive component 20, ensuring a certain degree of safety redundancy. It should be noted that the front and rear ends refer to the two ends opposite each other in the direction of movement of the container 60.

[0078] In some embodiments, such as Figure 1 and Figure 6 As shown, the container loading and unloading fixing device 100 may further include a first guide roller assembly 40 and a second guide roller assembly 50. Two first guide roller assemblies 40 may be arranged in parallel to guide the sliding surfaces 62 on both sides of the bottom of the container 60. Two second guide roller assemblies 50 may be arranged opposite each other to guide the two opposite sides of the container 60. Simultaneously, the two second guide roller assemblies 50 can limit the movement of the container 60, ensuring that the locking engagement part 61 at the bottom of the container 60 can accurately engage with the locking member 11 of the towing assembly 10.

[0079] In some embodiments, the first guide roller assembly 40 and the second guide roller assembly 50 may each consist of a mounting frame and a plurality of guide rollers located on the mounting frame. The first guide roller assembly 40 and the second guide roller assembly 50 may be fixed to the transport platform 200 by the mounting frame to achieve the guiding function for loading and unloading of the container 60.

[0080] like Figure 10 As shown in the illustration, this application also discloses a transport platform 200, including a vehicle body 201 and a container loading and unloading fixing device 100 as disclosed in the above embodiment, located within the vehicle body 201. Therefore, this container loading and unloading fixing device 100 possesses all the technical effects of the aforementioned container loading and unloading fixing device 100, which will not be repeated here. The sides of the vehicle body 201 can be designed to be open to facilitate the loading and unloading of the containers 60. Simultaneously, two container loading and unloading fixing devices 100 can be used, and a support bracket 202 is provided inside the vehicle body 201. The two container loading and unloading fixing devices 100 can be located on opposite sides of the support bracket 202, allowing multiple containers 60 to be loaded and unloaded simultaneously via the transport platform 200, thus improving the transportation and operational efficiency of the transport platform 200.

[0081] This application also discloses a container loading and unloading method, applicable to the transport platform 200 disclosed in the above embodiments, and therefore possesses all the technical effects of the transport platform 200, which will not be repeated here. The container loading and unloading method may include steps of loading the container and steps of unloading the container.

[0082] When loading container 60, such as Figures 6 to 8As shown, when the container 60 is pushed into the target position of the container loading and unloading fixing device 100 by an external force, the locking member 11 locks into the locking engagement part 61 at the bottom of the container 60, and the drive assembly 20 can drive the towing assembly 10 and the container 60 to move to the preset loading position. Specifically, first, after the empty transport platform 200 stops, the ground control system determines the loading direction of the container 60, and the control system moves the towing assembly 10 to the corresponding position of the loading direction in advance. Then, the ground transfer trolley with power transports the container 60 to be aligned with the transport platform 200. After alignment, the container 60 is pushed into the target position by an external force. The container 60 is in the initial stage of the loading process, that is, it is pushed by an external force, such as a forklift, AGV trolley, manual pushing or conveyor belt system, so that it enters the initial receiving area or sensing area of ​​the container loading and unloading fixing device 100. The target position can be a position that allows the locking member 11 to be initially aligned with the locking engagement part 61, or a position where the locking member 11 is locked to the locking engagement part 61 at the bottom of the container 60. For example, the target position can be one-third of the way along the loading direction of the container 60 on the container loading and unloading fixing device 100. When the container 60 reaches the target position, the locking member 11 of the container loading and unloading fixing device 100 will automatically lock mechanically with the locking engagement part 61 at the bottom of the container 60 under the elastic force of the reset elastic member 12. Once the container 60 is firmly fixed by the locking member 11, the drive assembly 20 will start and, through the transmission connection with the towing assembly 10, drive the entire towing assembly 10 and the locked container 60 thereon to move to the final preset loading position, i.e., the final parking position on the transport platform 200. Once the container 60 is in place, the drive motor 222 of the drive assembly 20 activates its braking function to ensure that the towing assembly 10 stops moving. Simultaneously, the locking telescopic member 31 of the locking assembly 30 extends, allowing the angled fixing seat 32 to provide secondary fixation to the container 60, thus completing the loading of the container 60. It should be noted that when the locking member 11 of the container loading and unloading fixing device 100 automatically engages with the locking mating part 61 at the bottom of the container 60 under the elastic force of the reset elastic member 12, the position detection element 15 monitors the movement of the locking member 11 and inputs a signal indicating that the container 60 has been loaded to the control system.

[0083] When unloading container 60, such as Figure 9As shown, the drive assembly 20 can drive the drag assembly 10 and the container 60 to move to the preset unloading position, and the release mechanism 13 drives the locking member 11 to disengage from the locking engagement part 61, so that the container 60 can be unloaded under the action of external force. Specifically, after the transport platform 200 stops, the unloading direction of the container 60 is input by the ground control system. For example, it can be unloaded on the same side as the loading side of the container 60, or it can be unloaded on the opposite side of the loading side of the container 60, that is, unloaded on the opposite side of the loading container 60. Then, the locking telescopic member 31 of the locking component 30 can be retracted first, and then the unloading operation can be performed. At this time, the drive component 20 will start again, driving the drag component 10 and the container 60 locked on it to move from the current loading position to the preset unloading position. The preset unloading position can be located at the exit of the container loading and unloading fixing device 100, that is, on both sides of the vehicle body 201. For example, the preset unloading position can be that the container 60 is pushed out of the container loading and unloading fixing device 100 at 2 / 3 of the unloading direction, so that external equipment such as ground transfer trolleys or manual labor can move the container 60 away. When the container 60 reaches the preset unloading position, the release mechanism 13 is activated, allowing it to exert force on the locking member 11 through its internal release telescopic member 131 and release member 132, causing it to overcome the elastic force of the reset elastic member 12 and rotate around its rotating pin 113, thereby separating it from the locking engagement part 61 of the container 60. Once the locking member 11 disengages from the locking engagement part 61, the container 60 is no longer secured by the container loading and unloading fixing device 100 and can be moved away from the side of the vehicle body 201 under the action of external force.
