Description

TECHNICAL FIELD

[0001] The present application relates to the field of loading and unloading transportation technology, in particular to a rapid loading and unloading device for offshore containers. BACKGROUND

[0002] With the vigorous development of global trade and regional economy, offshore container transportation has become an important logistics mode connecting small ports, islands and coastal areas due to its flexibility and efficiency. However, compared with inland large ports with deep water berths and large specialized equipment, the transfer operation of offshore containers faces unique and severe technical challenges.

[0003] Offshore transfer is completely different from the calm inland port area. It usually occurs in open barge wharfs, which are mostly lifted and assembled by cranes or forklifts, and then transferred and unloaded by AGV trolleys. However, there are many problems when coordinating with cranes and forklifts, as follows: Although the traditional crane on the wharf can complete lifting, the steel rope suspension system will cause the container to swing violently in the air when the ship sways with the waves, which not only makes it difficult to align with the AGV trolley and reduces the loading and unloading efficiency, but also causes the container to collide with the containers stacked on the wharf during movement, posing a huge safety risk.

[0004] Specifically, the longitudinal or transverse corner points of the container fail to align with the main body of the AGV trolley, causing the container to be suspended in an inclined state above the AGV trolley; or, the container is roughly positioned, but its center of gravity is seriously offset from the geometric center of the AGV trolley bearing surface. At this time, if forcibly locked or simply lowered, a static but unbalanced load is applied to the AGV trolley, and an unbalanced container will cause the AGV trolley's bearing structure (such as the frame and bearings) to bear additional torsional load, and long-term or short-term overload will cause metal fatigue, deformation or even breakage.

[0005] Therefore, the present application proposes a rapid loading and unloading device for offshore containers to solve the above-mentioned defects. SUMMARY

[0017] The technical scheme provided by the embodiment of the present application has at least the following beneficial effects: The present application creatively sets the loading and unloading function directly on the AGV trolley, so that the AGV trolley is upgraded from a passive transportation unit to an active loading and unloading terminal. Through the motor-driven carrying roller group in the carrying unit, the container can be quickly received or transferred from the ship or the yard to the inside of the frame of the device, so that the loading and unloading are realized in place, the time delay caused by the waiting of the AGV trolley for the external crane or forklift is completely eliminated, the offshore transfer process can be continuously and smoothly carried out, and the operation efficiency is improved by orders of magnitude.

[0018] Real-time posture monitoring is performed on the suspended container by a position scanner. Once it is detected that the corner points of the container and the bearing surface of the AGV trolley are misaligned or the center of gravity is offset, the system can immediately drive the second hydraulic cylinder to push the support seat and the upper positioning table to move horizontally, and at the same time, the positioning table is rotated by the first motor, so as to finely adjust the container in the horizontal and circumferential directions. The active correction mechanism can effectively compensate for the inaccurate position caused by the wave fluctuation of the lifting appliance or the operation error, ensure that the container can be accurately seated and locked on the AGV trolley in a balanced and stable state, and fundamentally eliminate the major safety hazards such as stress concentration of the AGV trolley body, abnormal wear of the driving system and even overturning during operation caused by the unbalanced load.

[0019] The cooperation of the clamping assembly and the rotating swing piece of the present application can be adjusted in real time according to the two different forms of lifting and forklift placement. When cooperating with the lifting mechanism, the movable abutment plate is locked in the vertical state by the clamping assembly and cooperates with the fixed abutment plate to firmly clamp the container from both sides. This all-around constraint not only enhances the stability during lifting, but also effectively suppresses the swing of the container, realizes clamping type anti-swing, and greatly improves the operation safety.

[0020] When cooperating with the forklift for loading and unloading, the movable abutment plate can be rotated outward and flattened under the drive of the hydraulic cylinder by releasing the locking of the clamping assembly, thereby leaving a spacious access channel for the forks of the forklift. This design enables the device to perfectly adapt to the traditional forklift operation mode without any modification to the existing forklift process, greatly widening the application scenarios of the device and solving the compatibility problem of automatic equipment and traditional process.

DETAILED DESCRIPTION

[0032] In order to make the person in the art better understand the technical scheme in the embodiment of the present application, the technical scheme of the present application will be described clearly and completely below in combination with the figures, obviously, the described embodiment is a part of the embodiment of the present application, and is not all the embodiment. It should be understood that these descriptions are only exemplary, and are not used to limit the scope of the present application. Based on the embodiment of the present application, all other embodiments obtained by the ordinary skilled in the art without making creative labor should belong to the scope of protection of the present application.

[0033] Furthermore, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts disclosed in the present disclosure.

[0034] Exemplary embodiments will be described in detail with reference to the drawings, of which examples are shown. In the following description, like reference numerals refer to like elements unless the context clearly dictates otherwise. The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the present disclosure.

[0035] Reference is made to the drawings Figures 1 to 8 The embodiment of the present application provides a rapid loading and unloading device for offshore containers, which comprises an AGV trolley 1, a hydraulic lifting device 2, a scanning rod 18, a position scanner 21 and a stable frame 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 with the bottom of the stable frame 24. A frame 3 is fixedly installed on the upper part of the stable frame 24. A rotating unit is arranged in the frame 3. Bottom beams 8 are fixedly installed on both sides of the bottom of the frame 3. Carrying units are arranged on the outer walls of the sides away from each other of the two bottom beams 8. Telescopic box clamping units are arranged at both ends in the two bottom beams 8. Box adjusting units are arranged at both ends of the stable frame 24 away from the carrying units. In a possible implementation, when the AGV trolley 1 autonomously navigates to a predetermined position below the container, the hydraulic lifting device 2 is started to lift the stable frame 24 and the entire frame 3, so that the bearing surface on the frame 3 is in contact with the bottom surface of the container and bears the weight of the container. The rotating unit in the frame 3 is used for low-friction receiving. The box adjusting units arranged at both ends of the stable frame 24 are responsible for fine adjustment of the position and posture of the container when the container falls onto the bearing surface. After the fine adjustment is completed, the telescopic box clamping units on the bottom beams 8 are responsible for clamping the container from both sides. The carrying units are used for horizontal exchange of the container with the wharf conveying equipment. The above achieves the integration of loading and unloading and transportation functions at the wharf, and realizes seamless connection of offshore wharf transfer.

[0036] The box adjusting unit further comprises two guide rods 14, a support seat 19, a barrel shell 17, a position adjusting table 20 and a second hydraulic cylinder 23. One end of the second hydraulic cylinder 23 is fixedly installed on the outer side of the stable frame 24. The telescopic end of the second hydraulic cylinder 23 is connected with the outer side of the support seat 19. The barrel shell 17 is installed through the inside of the support seat 19. A driving unit is arranged below the barrel shell 17. One end of the driving unit is connected with the position adjusting table 20. Two guide rods 14 are fixedly installed on the outer wall of the stable frame 24 and close to both sides of the second hydraulic cylinder 23. The support seat 19 is slidably sleeved on the outside of the two guide rods 14. In a possible implementation, the horizontal movement of the adjusting unit is the basis for the alignment, the unit is provided with a horizontal driving force by the second hydraulic cylinder 23, and the movement stability is ensured by the two guide rods 14. One end of the guide rod 14 is fixedly connected to the outside of the stabilizing frame 24, and the support seat 19 is sleeved on the two guide rods 14 through a linear bearing or a sliding sleeve; Specifically, when the second hydraulic cylinder 23 is extended or retracted, the support seat 19 and the entire scanning and adjusting mechanism thereon are pushed to slide along the guide rods 14 in the axial direction. The guide rods 14 form a high-rigidity movement pair, effectively resisting the overturning moment that may be generated due to the overhanging of the mechanism, and ensuring that the entire adjusting unit does not shake or jam during horizontal movement.

[0037] The driving unit includes a first motor 9 fixedly installed below the barrel shell 17, the output shaft of the first motor 9 is fixedly connected with a rotating shaft 22, the upper end of the rotating shaft 22 is embedded in the middle of the adjusting table 20, the scanning rods 18 are two in number and are fixedly installed on the outer wall of the support seat 19 on both sides, and the position scanners 21 are a plurality of and are fixedly installed above the two scanning rods 18; In a possible implementation, the driving unit realizes multi-angle rotation adjustment of the adjusting table 20, can correct the deflection angle of the container due to the sea wave swing or initial placement deviation during hoisting, ensures that the longitudinal center line of the container is consistent with the bearing surface of the AGV trolley 1, and guarantees the correct transportation posture and prevents deviation. Specifically, when the position scanners 21 detect that the container needs to be adjusted in the circumferential direction, the first motor 9 is started. The output torque of the first motor 9 is directly transmitted to the adjusting table 20 above through the rotating shaft 22, driving the adjusting table 20 to rotate around its own axis. The barrel shell 17 serves as the main supporting structure, has bearings inside, bears part of the weight of the adjusting table 20 and the container, and ensures the flexibility of rotation; It should be noted that the plurality of position scanners 21 are infrared laser scanners, which are connected to the AGV trolley 1 main body through external wires. The AGV trolley 1 is composed of a bearing framework, a platform, a battery module, a guide sensor, a main controller, a driver, and a safety braking system structure, which are all prior art and will not be described in detail.

[0038] The rotating unit includes a plurality of rotating rollers 5, which are installed in the frame 3 in the horizontal direction at equal distances. In a possible implementation, the plurality of rotating rollers 5 greatly reduce the resistance of the container moving inside the device, not only saving power consumption, but also reducing the wear of the bottom of the container, and making accurate positioning easier and more efficient. Specifically, when the container needs to be transported from above, its bottom surface first contacts the plurality of rotating rollers 5. Since the rotating rollers 5 can rotate freely, the sliding friction between the container and the frame 3 is converted into rolling friction. When the container needs to be moved laterally, only a small pushing force is needed to make it easily slide on the frame 3.

[0039] The carrying unit comprises a mounting rack 7, a plurality of carrying rollers 16, a synchronous chain 13, and a second motor 12. The mounting rack 7 is fixedly mounted on one side of the outer wall of the frame 3. The plurality of carrying rollers 16 are equidistantly mounted inside the mounting rack 7 in the horizontal direction. The plurality of carrying rollers 16 are each fixedly sleeved with a sprocket at one end thereof. The synchronous chain 13 is collectively sleeved outside the plurality of sprockets. One end of one of the plurality of carrying rollers 16 is connected to the output end of the second motor 12. The second motor 12 is connected to the outer side of the mounting rack 7 through the bracket fixedly connected below. In a possible implementation, the second motor 12 serves as a power source and drives the carrying rollers 16 mounted in the mounting rack 7 to rotate synchronously through the synchronous chain 13. Specifically, when loading and unloading operations are needed, the second motor 12 is started to uniformly transmit power to the carrying rollers 16 through the synchronous chain 13. The carrying rollers 16 rotating in the same direction generate frictional force to drive the container to enter or leave the frame 3 of the device laterally. The mounting rack 7 provides firm support for the entire unit.

[0040] The telescopic container clamping unit comprises two groups of movable abutting plates 4, two groups of fixed abutting plates 6, four groups of first hydraulic cylinders 10, four groups of connecting joints 15, and two groups of abutting blocks 29. The two groups of abutting blocks 29 are rotatably connected to the two groups of movable abutting plates 4 through the rotating pivots. The four groups of first hydraulic cylinders 10 are symmetrically installed at both ends of the corresponding bottom beams 8. The telescopic ends of the two groups of first hydraulic cylinders 10 corresponding to one side of the movable abutting plates 4 are fixedly connected to the two groups of abutting blocks 29. The telescopic ends of the two groups of first hydraulic cylinders 10 corresponding to one side of the fixed abutting plates 6 are fixedly connected to the outer side of the fixed abutting plates 6. Two abutting columns 11 are installed on the outer walls of the two groups of movable abutting plates 4 and the two groups of fixed abutting plates 6 on the sides close to each other. The outer walls of the abutting columns 11 are made of wear-resistant rubber material. The rotating pivot comprises a fixed shaft 26 fixedly inserted into the movable abutting plate 4 below. The outer ends of the fixed shaft 26 are fixedly sleeved with connecting rods 27. The abutting block 29 is fixedly inserted with a connecting shaft 28. The connecting rod 27 remote from the fixed shaft 26 is rotatably connected to the connecting shaft 28. The outer wall of the abutting block 29 is provided with a clamping assembly. The clamping assembly comprises an L-shaped frame 31 fixedly installed on one side of the outer wall of the abutting block 29. The L-shaped frame 31 is fixedly installed with a third hydraulic cylinder 30. The telescopic end of the third hydraulic cylinder 30 is provided with a limiting sliding table 25. The limiting sliding table 25 is provided with a limiting groove 32 in the inside. The inner walls of the limiting sliding table 25 are movably attached to the outer walls of the connecting rod 27 and the abutting block 29 on both sides. In a possible implementation, the fixed abutting plate 6 is directly driven by the first hydraulic cylinder 10 to move linearly. The movable abutting plate 4 is connected with the abutting block 29 through the rotating swing piece, and the abutting block 29 is driven by another group of first hydraulic cylinders 10. Specifically, the rotating swing piece is composed of a fixed shaft 26, a connecting rod 27 and a connecting shaft 28. The fixed shaft 26 is fixed at the lower part of the movable abutting plate 4, one end of the connecting rod 27 is fixedly connected with the fixed shaft 26, and the other end is connected with the abutting block 29 through the connecting shaft 28 to form a rotating pair. In this way, two modes are adapted: If the forklift is matched, the third hydraulic cylinder 30 is retracted to drive the limiting sliding table 25 to move upwards, thereby releasing the constraint on the connecting rod 27 and the abutting block 29. At this time, the movable abutting plate 4 can be freely rotated to leave space for the forklift fork.

[0041] If the crane is matched, when the movable abutting plate 4 is rotated to the vertical position, the third hydraulic cylinder 30 is extended to push the limiting sliding table 25 to move downwards, so that the limiting groove 32 on the limiting sliding table 25 simultaneously clamps the side surface of the connecting rod 27 and the abutting block 29. At this time, the inner wall of the limiting sliding table 25 is tightly fitted with the connecting rod 27 and the abutting block 29 to form a limiting structure, which effectively prevents the movable abutting plate 4 from swinging backward when clamping under force, thereby ensuring the firmness of clamping; It should be noted that when the AGV trolley 1 is running, the movable abutting plate 4 needs to be adjusted to the vertical state, and then the container is clamped.

[0042] The present application realizes the rapid and accurate alignment and balanced seating of the container in the dynamic environment by setting the container adjusting unit and the position scanner 21 on the AGV trolley 1, and fundamentally eliminates the risk of AGV transportation unbalanced load. The innovative telescopic container clamping unit has two working modes: when matched with the lifting mechanism, it can firmly clamp the container to realize clamping type anti-shaking; when matched with the forklift, the movable abutting plate 4 can be rotated to be flat to reserve the operation space for the forklift, thereby showing excellent multi-scene adaptability.

In order to make the public have a thorough understanding of the present application, specific details are described in the preferred embodiments of the present application, and the present application can also be completely understood without the description of these details for those skilled in the art.
