Description

Technical Field

[0001] This invention relates to the field of loading and unloading transportation technology, and in particular to a rapid loading and unloading device for near-shore containers. Background Technology

[0002] With the booming development of global trade and regional economies, offshore container shipping has become an important logistics mode connecting small ports, islands, and coastal areas due to its flexibility and efficiency. However, compared with large inland ports with deep-water berths and large-scale specialized equipment, offshore container transshipment operations face unique and severe technical challenges.

[0003] Offshore transshipment is entirely different from the calm waters of inland ports. It typically occurs at open barge wharves, where cranes or forklifts are mostly used for lifting and assembling, followed by AGV (Automated Guided Vehicle) carts to complete the transshipment and loading / unloading work. However, coordinating with cranes and forklifts can lead to several problems, specifically as follows:

[0004] While traditional cranes at the dock can lift containers, their steel cable suspension systems cause containers to sway violently in the air when the ship moves with the waves. This not only makes it difficult to align with AGVs and reduces loading and unloading efficiency, but also poses a significant safety risk as the containers may collide with other containers stacked at the dock due to instability during movement.

[0005] Specifically, this manifests as follows: the longitudinal or lateral corners of the container fail to align with the main body of the AGV, causing the container to be suspended at an angle above the AGV; or, although the container is roughly positioned, its center of gravity projection is significantly deviated from the geometric center of the AGV's load-bearing surface. In this case, if it is forcibly locked or simply lowered, a static but unbalanced load is applied to the AGV. An unbalanced container causes the AGV's load-bearing structure (such as the frame and bearings) to bear additional torsional loads, and long-term or short-term overload can lead to metal fatigue, deformation, or even fracture.

[0006] Therefore, this invention proposes a rapid loading and unloading device for near-shore containers to solve the above-mentioned defects. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide a rapid loading and unloading device for near-shore containers, which can solve the technical problems of low loading and unloading efficiency and poor adaptability in the prior art.

[0008] The technical solutions provided by the embodiments of the present invention are as follows:

[0009] This invention provides a rapid loading and unloading device for near-shore containers, comprising an AGV trolley, a hydraulic lifting device, a scanning rod, a position scanner, and a stabilizing platform. The hydraulic lifting device is installed in the middle of the AGV trolley, and its upper part is connected to the bottom of the stabilizing platform. A frame is fixedly installed on the top of the stabilizing platform, and a rotating unit is provided inside the frame. Bottom beams are fixedly installed on both sides of the bottom of the frame. A transport unit is provided on the outer wall of the side of the two bottom beams that are far apart from each other. Telescopic container clamping units are provided at both ends inside the two bottom beams. Container adjusting units are provided at both ends of the stabilizing platform that are far away from the transport units.

[0010] The adjustment unit also includes two guide rods, a support base, a cylindrical shell, an adjustment platform, and a second hydraulic cylinder. One end of the second hydraulic cylinder is fixedly installed on the outside of the stabilizing frame, and the telescopic end of the second hydraulic cylinder is connected to the outside of the support base. The cylindrical shell is installed through the support base, and a drive unit is provided below the cylindrical shell. One end of the drive unit is connected to the adjustment platform.

[0011] In the above technical solution, one end of each of the two guide rods is fixedly installed on the outer wall of the stabilizing frame and on both sides near the second hydraulic cylinder, and the support base is slidably sleeved on the outside of the two guide rods.

[0012] In the above technical solution, the drive unit further includes a first motor fixedly installed below the cylindrical shell, the output shaft of the first motor is fixedly connected to a rotating shaft, and the upper end of the rotating shaft is embedded in the middle of the adjustment platform.

[0013] In the above technical solution, the rotating unit further includes multiple rotating rollers, which are equidistantly mounted inside the frame in a horizontal direction.

[0014] In the above technical solution, the transport unit further includes a mounting frame, multiple transport rollers, a synchronous chain, and a second motor. The mounting frame is fixedly installed on one side of the outer wall of the frame. The multiple transport rollers are installed at equal intervals along the horizontal direction inside the mounting frame. A sprocket is fixedly sleeved on the outside of one end of each of the multiple transport rollers. The synchronous chain is sleeved on the outside of the multiple sprockets. One end of one of the transport rollers is connected to the output end of the second motor. The outside of the second motor is connected to the outside of the mounting frame through a bracket fixedly connected below.

[0015] In the above technical solution, the telescopic clamping box unit further includes two sets of movable support plates, two sets of fixed support plates, four sets of first hydraulic cylinders, four sets of connecting sections, and two sets of abutment blocks. The two sets of abutment blocks are rotatably engaged with the two sets of movable support plates through a set rotating swing member. The four sets of first hydraulic cylinders are symmetrically installed in pairs at both ends inside the corresponding bottom beam. The telescopic ends of the two sets of first hydraulic cylinders on the side corresponding to the movable support plate are fixedly connected to the two sets of abutment blocks, and the telescopic ends of the two sets of first hydraulic cylinders on the side corresponding to the fixed support plate are fixedly connected to the outside of the fixed support plate.

[0016] In the above technical solution, furthermore, two abutment columns are installed on the upper and lower sides of the outer walls of the two sets of movable abutment plates and the two sets of fixed abutment plates that are close to each other, and the outer walls of the abutment columns are made of wear-resistant rubber material.

[0017] In the above technical solution, the rotating swing component further includes a fixed shaft that is fixedly inserted into the lower part of the movable support plate. Both ends of the fixed shaft are fixedly sleeved with connecting rods. The support block has a connecting shaft fixedly inserted inside. The end of the connecting rod away from the fixed shaft is rotatably engaged with the connecting shaft. A locking component is provided on one side of the outer wall of the support block.

[0018] In the above technical solution, the positioning component further includes an L-shaped frame fixedly installed on one side of the outer wall of the abutment block. A third hydraulic cylinder is fixedly installed inside the L-shaped frame. A limiting slide is provided at the telescopic end of the third hydraulic cylinder. A limiting groove is opened inside the limiting slide. The two sides of the inner wall of the limiting slide are movably fitted with the connecting rod and the two outer walls of the abutment block.

[0019] In the above technical solution, there are two scanning rods, and the two scanning rods are respectively fixedly installed on both sides of the outer wall of the support base. There are several position scanners, and the several position scanners are respectively fixedly installed above the two scanning rods.

[0020] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0021] This invention creatively integrates loading and unloading functions directly onto the AGV (Automated Guided Vehicle), upgrading it from a passive transport unit to an active loading and unloading terminal. Through motor-driven rollers within the transport unit, containers can be quickly received or transferred laterally from ships or yards into the frame of this device, achieving immediate loading and unloading upon arrival. This completely eliminates the time delay caused by the AGV waiting for external cranes or forklifts, enabling continuous and smooth near-shore transshipment processes and resulting in an order-of-magnitude improvement in operational efficiency.

[0022] The system monitors the suspended container's attitude in real time using a position scanner. If any misalignment or center of gravity shift is detected between the container's corner and the AGV's load-bearing surface, the system immediately activates a second hydraulic cylinder to move the support base and the upper adjustment platform horizontally. Simultaneously, a first motor drives the adjustment platform to rotate, thus fine-tuning the container's lateral and circumferential directions. This active correction mechanism effectively compensates for positional inaccuracies caused by wave-induced spreader fluctuations or operational errors, ensuring the container is precisely positioned and locked onto the AGV in a balanced and stable state. This fundamentally eliminates the significant safety hazards of stress concentration on the AGV body, abnormal wear of the drive system, and even overturning during operation caused by uneven loading.

[0023] The synergistic cooperation of the positioning component and the rotating swing element in this invention allows for real-time adjustment based on two different placement configurations: hoisting and forklift operation. When used with a hoisting mechanism, the movable stop plate is locked in a vertical position by the positioning component, working in conjunction with the fixed stop plate to securely clamp the container from both sides. This comprehensive constraint not only enhances stability during hoisting but also effectively suppresses container swaying, achieving clamping anti-sway and significantly improving operational safety.

[0024] When used in conjunction with a forklift for loading and unloading: By releasing the locking mechanism, the movable stop can rotate outward and flatten under the drive of a hydraulic cylinder, thus creating a wide passage for the forklift forks to enter and exit. This design allows the device to perfectly adapt to traditional forklift operation modes without requiring any modifications to existing forklift processes, greatly expanding the applicable scenarios of the device and solving the compatibility problem between automated equipment and traditional processes.

[0036] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0039] Reference manual attached Figures 1 to 8 The present invention provides a rapid loading and unloading device for near-shore containers, including an AGV trolley 1, a hydraulic lifting device 2, a scanning bar 18, a position scanner 21, and a stabilizing platform 24. The hydraulic lifting device 2 is installed in the middle of the AGV trolley 1, and the upper part of the hydraulic lifting device 2 is connected to the bottom of the stabilizing platform 24. A frame 3 is fixedly installed on the upper part of the stabilizing platform 24. A rotating unit is provided inside the frame 3. Bottom beams 8 are fixedly installed on both sides of the bottom of the frame 3. A transport unit is provided on the outer wall of the side of the two bottom beams 8 that is far away from each other. Telescopic container clamping units are provided at both ends of the two bottom beams 8. Container adjustment units are provided at both ends of the stabilizing platform 24 that are far away from the transport units.

[0040] In one possible implementation, after the AGV trolley 1 autonomously navigates to a predetermined position under the container, the hydraulic lifting device 2 is activated, lifting the stabilizing platform 24 and the entire frame 3, so that the bearing surface on the frame 3 contacts the bottom surface of the container and supports its weight. The rotating unit inside the frame 3 is used for low-friction receiving; while the container adjustment unit located at both ends of the stabilizing platform 24 is responsible for fine-tuning the position of the container when it falls onto the bearing surface; after the fine-tuning is completed, the telescopic container clamping unit on the bottom beam 8 is responsible for clamping the container from both sides; the transport unit is used for lateral exchange of containers with the terminal conveyor equipment;

[0041] The above achieves the integration of loading, unloading and transportation functions at the dock, and realizes seamless connection of transshipment at near-shore docks.

[0042] The adjustment unit also includes two guide rods 14, a support base 19, a cylindrical shell 17, an adjustment platform 20, and a second hydraulic cylinder 23. One end of the second hydraulic cylinder 23 is fixedly installed on the outside of the stabilizing frame 24, and the telescopic end of the second hydraulic cylinder 23 is connected to the outside of the support base 19. The cylindrical shell 17 is installed through the inside of the support base 19. A drive unit is provided below the cylindrical shell 17. One end of the drive unit is connected to the adjustment platform 20. One end of the two guide rods 14 is fixedly installed on the outer wall of the stabilizing frame 24 and on both sides close to the second hydraulic cylinder 23. The support base 19 is slidably sleeved on the outside of the two guide rods 14.

[0043] In one possible implementation, the horizontal movement of the box-changing unit is the basis for achieving alignment. This unit is provided with horizontal driving force by a second hydraulic cylinder 23, while its motion stability is ensured by two guide rods 14. One end of the guide rod 14 is firmly fixed to the outside of the stabilizing frame 24, and the support base 19 is slidably sleeved on the two guide rods 14 by a linear bearing or a sliding sleeve.

[0044] Specifically, when the second hydraulic cylinder 23 extends or retracts, it pushes the support base 19 and the entire scanning and adjusting mechanism on it to slide precisely along the axial direction of the guide rod 14. The guide rod 14 forms a highly rigid kinematic pair, effectively resisting the overturning moment that may be generated by the mechanism's extension, ensuring that the entire box-adjusting unit moves horizontally without shaking or jamming.

[0045] The drive unit includes a first motor 9 fixedly installed below the cylindrical shell 17. The output shaft of the first motor 9 is fixedly connected to a rotating shaft 22. The upper end of the rotating shaft 22 is embedded in the middle of the adjustment platform 20. There are two scanning rods 18, and the two scanning rods 18 are respectively fixedly installed on both sides of the outer wall of the support base 19. There are several position scanners 21, and the several position scanners 21 are respectively fixedly installed above the two scanning rods 18.

[0046] In one possible implementation, the drive unit realizes the rotation adjustment of the adjustment platform at more than 20 angles, which can correct the deflection angle of the container caused by the swing of the sea waves or the initial placement deviation during hoisting, and ensure that its longitudinal center line is consistent with the bearing surface of the AGV trolley 1, thus ensuring the correct transportation posture and preventing deviation.

[0047] Specifically, when the position scanner 21 detects that the container needs circumferential angle adjustment, the first motor 9 starts. The output torque of the first motor 9 is directly transmitted to the upper adjustment platform 20 through the rotating shaft 22, driving it to rotate around its own axis. The cylindrical shell 17, as the main support structure, is equipped with bearings inside, which not only bear part of the weight of the adjustment platform 20 and the container, but also ensure its rotational flexibility;

[0048] It should be noted that the multiple position scanners 21 are infrared laser scanners, which are connected to the main body of the AGV trolley 1 via external wires;

[0049] The AGV trolley 1 consists of a supporting frame, platform, battery module, guidance sensors, main controller, driver, and safety braking system, which is existing technology and will not be described in detail.

[0050] The rotating unit includes multiple rotating rollers 5, which are installed inside the frame 3 at equal distances along the horizontal direction;

[0051] In one possible implementation, multiple rotating rollers 5 greatly reduce the resistance of the container moving inside the device, which not only saves power consumption but also reduces wear on the bottom of the container, while making precise positioning easier and more efficient.

[0052] Specifically, when the container needs to be moved from above, its bottom surface first contacts multiple rotating rollers 5. Since the rollers 5 can rotate freely, the sliding friction between the container and the frame 3 is converted into rolling friction. When lateral movement of the container is required, only a small pushing force is needed to allow it to slide easily on the frame 3.

[0053] The transport unit includes a mounting frame 7, multiple transport rollers 16, a synchronous chain 13, and a second motor 12. The mounting frame 7 is fixedly installed on one side of the outer wall of the frame 3. The multiple transport rollers 16 are installed at equal intervals in the horizontal direction inside the mounting frame 7. A sprocket is fixedly sleeved on the outside of one end of each of the multiple transport rollers 16. The synchronous chain 13 is sleeved on the outside of the multiple sprockets. The end of one of the transport rollers 16 is connected to the output end of the second motor 12. The outside of the second motor 12 is connected to the outside of the mounting frame 7 through a bracket fixedly connected below.

[0054] In one possible implementation, the second motor 12 serves as a power source, driving the transport roller 16 installed in the mounting frame 7 to rotate synchronously via the synchronous chain 13.

[0055] Specifically, when loading and unloading operations are required, the second motor 12 starts and transmits power evenly to the conveyor rollers 16 via the synchronization chain 13. The conveyor rollers 16, rotating in the same direction, generate friction, causing the container to move laterally into or out of the frame 3 of the device;

[0056] Mounting bracket 7 provides robust support for the entire unit.

[0057] The telescopic clamping box unit includes two sets of movable bearing plates 4, two sets of fixed bearing plates 6, four sets of first hydraulic cylinders 10, four sets of connecting sections 15, and two sets of abutment blocks 29. The two sets of abutment blocks 29 are rotatably engaged with the two sets of movable bearing plates 4 via rotating swing members. The four sets of first hydraulic cylinders 10 are symmetrically installed in pairs at both ends inside the corresponding bottom beams 8. The telescopic ends of the two sets of first hydraulic cylinders 10 on one side of the movable bearing plate 4 are fixedly connected to the two sets of abutment blocks 29, and the telescopic ends of the two sets of first hydraulic cylinders 10 on one side of the fixed bearing plate 6 are fixedly connected to the outer side of the fixed bearing plate 6. Two abutment posts 11 are installed on the upper and lower sides of the outer walls of the two sets of movable bearing plates 4 and the two sets of fixed bearing plates 6 that are close to each other. The outer walls of the abutment posts 11 are made of wear-resistant rubber. The rotating component includes a fixed shaft 26 that is fixedly inserted into the lower part of the movable support plate 4. Both ends of the fixed shaft 26 are fixedly sleeved with connecting rods 27. A connecting shaft 28 is fixedly inserted into the support block 29. The end of the connecting rod 27 away from the fixed shaft 26 is rotatably engaged with the connecting shaft 28. A locking assembly is provided on one side of the outer wall of the support block 29. The locking assembly includes an L-shaped frame 31 fixedly installed on one side of the outer wall of the support block 29. A third hydraulic cylinder 30 is fixedly installed inside the L-shaped frame 31. A limiting slide 25 is provided at the telescopic end of the third hydraulic cylinder 30. A limiting groove 32 is opened inside the limiting slide 25. The two sides of the inner wall of the limiting slide 25 are movably fitted with the connecting rod 27 and the two outer walls of the support block 29.

[0058] In one possible implementation, the fixed abutment 6 is directly driven by the first hydraulic cylinder 10 to perform linear motion. The movable abutment 4 is connected to the abutment block 29 via a rotating swing arm, and the abutment block 29 is driven by another set of first hydraulic cylinders 10.

[0059] Specifically, the rotating component consists of a fixed shaft 26, a connecting rod 27, and a connecting shaft 28. The fixed shaft 26 is fixed to the lower part of the movable stop plate 4, one end of the connecting rod 27 is fixed to the fixed shaft 26, and the other end forms a rotating pair with the stop block 29 through the connecting shaft 28.

[0060] This allows it to adapt to two forms:

[0061] When used in conjunction with a forklift, the third hydraulic cylinder 30 retracts, causing the limiting slide 25 to move upward, releasing the constraints on the connecting rod 27 and the stop block 29. At this time, the movable stop plate 4 can rotate freely, making room for the forklift forks.

[0062] When used in conjunction with a crane, when the movable stop plate 4 rotates to the vertical position, the third hydraulic cylinder 30 extends, pushing the limiting slide 25 downwards, causing the limiting groove 32 on it to simultaneously engage the sides of the connecting rod 27 and the stop block 29. At this time, the inner wall of the limiting slide 25 is tightly fitted with the connecting rod 27 and the stop block 29, forming a limiting structure that effectively prevents the movable stop plate 4 from swinging backwards when subjected to clamping force, ensuring the firmness of the clamping.

[0063] It should be noted that when the AGV trolley 1 is moving, the movable support plate 4 needs to be adjusted to a vertical position in order to clamp the container.

[0064] This invention, by installing a container adjustment unit and a position scanner 21 on the AGV trolley 1, achieves rapid and accurate alignment and balanced placement of containers in dynamic environments, fundamentally eliminating the risk of uneven loading during AGV transportation. Its innovative telescopic container clamping unit has two working modes: when used with a lifting mechanism, it can firmly clamp the container, achieving clamp-type anti-sway; when used with a forklift, the movable support plate 4 can rotate and flatten, reserving working space for the forklift, demonstrating excellent adaptability to multiple scenarios.
