DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] A heavy-duty material handling AGV device, such as Figures 1-9 As shown, it includes an AGV transport body 1, and the AGV transport body 1 is provided with a first placement groove 2 opening upward and at the rear side, and a movable plate 3 that can move laterally is provided in the first placement groove 2, and the rear side of the movable plate 3 is rotatably connected to a flip plate 4, and the surface of the flip plate 4 is hinged with a lifting plate 7 through a lifting assembly 9; when the flip plate 4 is flipped downward, the lifting plate 7 is located at the rear side of the flip plate 4.

[0022] Specifically, the first placing groove 2 opened upward and rearward on the AGV carrier body 1 provides a containing space for the lateral movement of the movable plate 3, ensuring that the movable plate 3 can be stably extended or retracted, which not only expands the lateral range of loading operation, but also can be stored in the non-use state to reduce the space occupation. The movable plate 3 can move laterally and can be extended to the outside of the AGV carrier body 1, which facilitates the pushing of the turnover plate 4 and the lifting plate 7 to a position close to the material, reducing the initial carrying distance of the material. The turnover plate 4 is rotatably connected to the rear side of the movable plate 3, and when it is turned downward, it can be in contact with the ground, forming an inclined support surface from the ground to the AGV carrier body 1, providing a stable load bearing foundation for the lifting plate 7, and at the same time reducing the height difference of the material transfer. The lifting assembly 9 on the surface of the turnover plate 4 moves up and down by driving the lifting plate 7, realizing the height adjustment of heavy load materials, and the lifting plate 7 is hinged to the lifting assembly 9 and can adapt to the angle change when the material is placed. When the turnover plate 4 is turned downward, the lifting plate 7 located at the rear side thereof can directly receive the heavy load material on the ground, and through the lifting assembly 9, the material is lifted to the same level as the load bearing surface of the AGV carrier body 1, facilitating the smooth translation of the material to the carrier body. It should be noted that all electrical equipment involved in the present application can be powered by a battery or an external power source.

[0023] When heavy load materials need to be loaded, the movable plate 3 moves laterally outward from the first placing groove 2 of the AGV carrier body 1, expanding the operating range; then, the turnover plate 4 at the rear side of the movable plate 3 is turned outward by two hundred and seventy degrees until it is perpendicular to the ground, at this time the lifting plate 7 is turned by ninety degrees and located at the rear side of the turnover plate 4, perpendicular to the turnover plate 4, in contact with the ground, facilitating the receipt of heavy load materials on the ground. After the operator places the material on the lifting plate 7, the lifting assembly 9 is started, driving the lifting plate 7 to move upward, lifting the material to the same height as the load bearing surface of the AGV carrier body 1; then, the material can be smoothly translated to the AGV carrier body 1, completing the loading. When unloading, the above process is reversed, and the lifting assembly 9 drives the lifting plate 7 to descend, conveying the material from the carrier body to the ground.

[0024] Through the cooperation of various components, a self-contained heavy load lifting and transfer system is formed. The existing AGV trolley hydraulic / electric lifting system can only slightly lower the vehicle body, and heavy load loading needs to rely on a forklift or manpower, which is laborious and inconvenient, and the material is easy to deviate and damage during transportation. However, through the unique structural design of the present device, a mechanism for independently completing the lifting and transfer of heavy load materials is constructed: the movable plate 3 can be moved laterally out of the first placing groove 2, expanding the operating range; the turnover plate 4 can be rotated to be perpendicular to the ground, forming a transition support; the lifting plate 7 is perpendicular to the turnover plate 4 through the rotating assembly 12, and cooperates with the lifting assembly 9 to realize the independent lifting of the material, without the need for external tools or a large amount of manpower, directly solving the problem of laborious loading.

[0025] As another specific embodiment, the movable plate 3 is provided with a second placing groove 5, the two sides of the first placing groove 2 are provided with a rack 21, the two sides of the movable plate 3 are provided with a gear 22 corresponding to the rack 21, the inner side of the gear 22 is connected with a driving wheel 23 through a transmission shaft, and the driving wheel 23 is arranged in the second placing groove 5; a driven wheel 24 is transmissionally connected at the rotating shaft of the turnover plate 4, and the driving wheel 23 and the driven wheel 24 are transmissionally connected through a chain or a belt 25. The second placing groove 5 provides an internal mounting space for the transmission components such as the turnover plate 4, the driving wheel 23 and the transmission shaft, which not only avoids collision damage caused by exposed components, but also makes the internal structure of the movable plate 3 more compact and saves space; the rack 21 on the two sides of the first placing groove 2 is engaged with the gear 22 on the two sides of the movable plate 3, forming a precise gear 22-rack 21 transmission pair, when the gear 22 rotates, the movable plate 3 can be driven to move stably transversely along the rack 21, replacing manual pulling, realizing mechanical driving of the movable plate 3 movement, and improving the moving precision and labor-saving property; the inner side of the gear 22 is connected with the driving wheel 23 through the transmission shaft, so that the rotating power of the gear 22 can be synchronously transmitted to the driving wheel 23 through the transmission shaft, forming an intermediate hub of power transmission; the driven wheel 24 at the rotating shaft of the turnover plate 4 and the driving wheel 23 are transmissionally connected through the chain or the belt 25, the rotation of the driving wheel 23 is converted into the rotation of the rotating shaft of the turnover plate 4, and then the linkage of the movable plate 3 movement and the turnover plate 4 turnover is realized - when the movable plate 3 moves outward, the gear 22 rotates along the rack 21, the driving wheel 23 is rotated through the transmission shaft, and the driving wheel 23 drives the driven wheel 24 through the chain / belt 25, finally driving the turnover plate 4 to automatically overturn downward, without the need for separate operation of the turnover plate 4. Optionally, the first placing groove 2 is provided with a limiting groove 301 on the two sides, and the movable plate 3 is fixedly connected with a limiting block 302 on the two sides, and the limiting block 302 slides in the limiting groove 301. The limiting groove 301 on the two sides of the first placing groove 2 and the limiting block 302 on the two sides of the movable plate 3 form a sliding fit, which further strengthens the constraint and guiding effect on the movement of the movable plate 3: the limiting groove 301 limits the movement track of the limiting block 302 through the groove profile, so that the movable plate 3 always smoothly slides along the preset path when moving transversely, avoiding the movable plate 3 from being skewed or deviated due to heavy load material pressure or movement inertia, ensuring the relative position accuracy of the movable plate 3 and the first placing groove 2; at the same time, when the limiting block 302 slides to the two ends of the limiting groove 301, it will be blocked by the end of the groove body, which can strictly limit the maximum movement distance of the movable plate 3, prevent the movable plate 3 from being completely pulled out of the first placing groove 2, and ensure the stability of the structure connection. When the automatic form is not adopted, the turnover plate 4 is provided with a lug 6, and the movable plate 3 is pulled outward to the AGV carrier body 1 through the lug 6.

[0026] As another specific embodiment, the lifting assembly 9 comprises a sliding groove 901 opened on one side of the turnover plate 4, a threaded rod 902 is rotatably matched in the sliding groove 901, the threaded rod 902 is connected with a transmission assembly 11, a first threaded block 903 is provided on the threaded rod 902 and is slidingly matched in the sliding groove 901, and the first threaded block 903 is rotatably connected with the lifting plate 7. The threaded transmission pair composed of the threaded rod 902 and the first threaded block 903 converts the rotary motion of the threaded rod 902 into the linear motion of the first threaded block 903. When the transmission assembly 11 drives the threaded rod 902 to rotate, the first threaded block 903 linearly slides along the sliding groove 901, and drives the lifting plate 7 to stably lift. Wherein, the thread angle with self-locking characteristic is adopted, which can lock the position of the lifting plate 7 when power is off or no power input, avoids the risk of sliding down caused by the weight of the material, and is suitable for heavy load scene. The sliding groove 901 provides an accurate sliding track for the first threaded block 903, limits the axial movement of the first threaded block 903 along the threaded rod 902, prevents the threaded block from rotating with the threaded rod 902, and ensures the perpendicularity of the lifting direction. At the same time, the sliding fit surface between the inner wall of the sliding groove 901 and the first threaded block 903 can bear the lateral force generated by the heavy load, avoids the shaking or deviation during lifting, and improves the structural rigidity. The rotary connection between the first threaded block 903 and the lifting plate 7 enables the lifting plate 7 to be turned to a horizontal state. Wherein, the first threaded block 903 is provided with a recess 1201 on one side, and a rotating rod 1202 is arranged in the recess 1201; the lifting plate 7 is provided with a connecting block 1204, the connecting block 1204 is sleeved on the rotating rod 1202, and the rotating rod 1202 is provided with a friction piece 1203 at the connecting position with the recess 1201. When heavy objects need to be carried, the lifting assembly 9 can be at least two, and the lifting assemblies 9 are connected through a shaft coupling to realize synchronous operation.

[0027] As another specific embodiment, the inner cavity 10 in communication with the chute 901 is arranged in the turnover plate 4, and the transmission assembly 11 is arranged in the inner cavity 10; the transmission assembly 11 comprises a first bevel gear 1101 fixedly connected with the threaded rod 902, a second bevel gear 1102 engaged with the first bevel gear 1101, and a driving member 1103 connected with the second bevel gear 1102. The inner cavity 10 in communication with the chute 901 in the turnover plate 4 provides a closed installation space for the transmission assembly 11, which not only avoids the exposure of the first bevel gear 1101, the second bevel gear 1102 and the driving member 1103 to the external environment such as dust and collision, but also makes the transmission components compactly integrated with the chute 901 and the threaded rod 902 of the turnover plate 4, thereby reducing the overall volume and improving the overall structural integrity. At the same time, the communication design of the inner cavity 10 and the chute 901 ensures that the first bevel gear 1101 can be fixedly connected with the threaded rod 902, thereby providing a direct path for power transmission. In this embodiment, the driving member 1103 can be horizontally installed along the length direction of the turnover plate 4, and through the engagement of the second bevel gear 1102 and the first bevel gear 1101, the horizontal rotating power is converted into the vertical rotation of the threaded rod 902, so that the driving member 1103 is more suitable for the long and narrow structure of the turnover plate 4, the structure of the turnover plate 4 is more compact, space conflicts are avoided, and the operation requirements of the narrow channel in the intelligent logistics park are adapted. The driving member 1103 serves as a power source to provide continuous torque for the entire transmission system, so that the threaded rod 902 can stably drive the first threaded block 903 and the lifting plate 7 to rise and fall, thereby meeting the power requirements of heavy loads. The driving member 1103 drives the second bevel gear 1102 to rotate, the second bevel gear 1102 drives the first bevel gear 1101 to rotate, the first bevel gear 1101 drives the threaded rod 902 to rotate, and the threaded rod 902 drives the first threaded block 903 to move in the channel 1601, the first threaded block 903 moves through the rotating assembly 12 to drive the lifting plate 7 to move, and the lifting plate 7 moves upward to drive the heavy load to move upward, As another specific embodiment, the active side of the lifting plate 7 is provided with an inclined surface 8, which is inclined downward when the lifting plate 7 is placed flat. When the lifting plate 7 is placed flat, the inclined surface 8 inclined downward can form a natural transition between the edge of the lifting plate 7 and the contact surface, eliminating the vertical height difference and further reducing the labor consumption in the loading and unloading process of heavy loads. It is especially suitable for large and heavy materials - without precise alignment of the edge of the lifting plate 7, the smooth transfer of the material can be realized through the inclined surface 8, reducing the operation difficulty; at the same time, the inclined surface 8 can disperse the contact stress between the material and the edge of the lifting plate 7, reduce the material wear or equipment damage caused by hard collision, and improve the operation safety.

[0028] As another specific embodiment, the AGV carrier body 1 is provided with a limiting plate 13 on each of the two side walls, and a relative moving assembly 16 connected with the two limiting plates 13 is arranged on one side of the AGV carrier body 1, and a pedal assembly 17 corresponding to the relative moving assembly 16 is arranged on one side of the AGV carrier body 1. The limiting plates 13 on both sides of the AGV carrier body 1 serve as direct constraint components, and can clamp heavy materials from both sides through relative movement, and the inner side can be fitted with a buffer material such as a rubber protective pad 18, which can not only enhance the friction with the materials, but also avoid damage to the materials caused by hard contact; the relative moving assembly 16 provides power transmission for the limiting plates 13, and through the built-in transmission structure, the power is converted into the synchronous relative movement of the two limiting plates 13, that is, when the assembly is started, the two limiting plates 13 can approach or move away at the same time, ensuring that the clamping force on the materials is uniform, and avoiding the materials from being skewed due to unilateral stress; the pedal assembly 17 serves as a human-computer interaction interface, and converts manual operation into the driving force of the relative moving assembly 16, without the need for complex electrical control or manual rotating components, and the operation is convenient and meets the needs of rapid operation in the logistics scene, especially suitable for foot-triggering when workers carry materials with both hands.

[0029] As another specific embodiment, the relative movement assembly 16 comprises a groove 1601 opened in the AGV carrier body 1, a bidirectional threaded rod 1602 is rotatably connected in the groove 1601, two second threaded blocks 1603 are respectively arranged at the two ends of the bidirectional threaded rod 1602, the two second threaded blocks 1603 are respectively fixedly connected with the two limiting plates 13, and the bidirectional threaded rod 1602 is in transmission connection with the pedal assembly 17. The AGV carrier body 1 is internally provided with a cavity 19 which is in communication with the groove 1601, and the pedal assembly 17 is arranged in the cavity 19. The pedal assembly 17 comprises a rotating disc 1702 arranged at one end of the bidirectional threaded rod 1602 close to the cavity 19, one end of a movable rod 1706 is rotatably connected to the rotating disc 1702 through a first pin shaft 1704, and the other end of the movable rod 1706 is rotatably connected to a pedal 1703 through a second pin shaft 1705. The cavity 19 is in communication with a slot 1701, the slot 1701 is provided with a support at the bottom, the pedal 1703 is located above the support, and the pedal 1703 is rotatably connected to the support. The reverse threads at the two ends of the bidirectional threaded rod 1602 are matched with the second threaded blocks 1603. When the pedal assembly 17 drives the bidirectional threaded rod 1602 to rotate, the two second threaded blocks 1603 will move in opposite directions synchronously, driving the limiting plates 13 to realize clamping or loosening action, ensuring the accurate synchronous movement of the two limiting plates 13, and avoiding the material deviation caused by uneven force on one side. The groove 1601 provides guidance and support for the second threaded blocks 1603, reduces the influence of lateral force on the threaded rod 902, and improves the transmission efficiency. When the pedal 1703 rotates around the rotating shaft on the support, the movable rod 1706 drives the rotating disc 1702 to rotate, and the pedaling action is converted into the circular motion of the bidirectional threaded rod 1602. The design of the cavity 19 and the slot 1701 not only protects the internal transmission components, but also provides a space for the pedal 1703 to move, ensuring smooth operation.

[0030] As another specific embodiment, a slot 1701 is opened in the AGV carrier body 1 of the embodiment, a placing plate is slidably connected in the slot 1701, a pressure sensor and a plurality of springs are arranged between the placing plate and the slot 1701, a sound-light alarm 20 is arranged on the AGV carrier body 1, a control box is fixedly arranged on the AGV carrier body 1, a power supply device, a processor, a data comparator and a feedback module are arranged in the control box, an output end of the pressure sensor is electrically connected with an input end of the data comparator, an output end of the data comparator is connected with an input end of the processor, an output end of the processor is electrically connected with an input end of the data comparator through the feedback module, an output end of the power supply device is electrically connected with an input end of the processor, and an output end of the processor is electrically connected with an input end of the sound-light alarm 20.

[0031] When the total weight of heavy load placed on the placement plate reaches a certain value, the placement plate compresses the pressure sensor, the pressure sensor transmits the overload signal to the processor, and the processor controls the sound and light alarm 20 to alarm, which can remind the operator not to transport too much, and is beneficial to the safe transportation of heavy load.

[0032] A loading method of a heavy load carrying AGV device, comprising the following steps: Step 1, the movable plate 3 moves out, and the turnover plate 4 is turned over 270° to a vertical state; a stable vertical support structure is formed, which serves as the installation basis of the lifting assembly 9 and provides vertical guidance for subsequent material lifting, solving the problem of lack of stable support of traditional AGV lifting structure.

[0033] Step 2, the lifting plate 7 is turned over 90° to the ground, and the inclined surface 8 is attached to the ground; the height difference between the lifting plate 7 and the ground is eliminated through the inclined surface 8, greatly reducing the resistance of the heavy load pushing onto the lifting plate 7, so that the material can move smoothly along the inclined surface 8 without lifting, avoiding the laborious operation of direct lifting, and adapting to the loading requirements of heavy load.

[0034] Step 3, the material is pushed onto the lifting plate 7 along the inclined surface 8; the guiding effect of the inclined surface 8 enables the material to be easily pushed onto the lifting plate 7 along the inclined surface 8, converting the vertical lifting of the material into horizontal thrust along the inclined surface 8, significantly reducing the consumption of manpower, and solving the inconvenience of relying on forklift or manpower lifting during traditional AGV loading.

[0035] Step 4, the lifting plate 7 is raised, and the material is raised to the same level as the carrying surface of the vehicle body; the lifting plate 7 is raised by the lifting assembly 9 to stably lift the material to the same level as the carrying surface of the AGV carrying vehicle body 1, providing a transition basis with consistent height for subsequent translation, avoiding material jamming or collision due to height difference, and ensuring stable and controllable lifting process.

[0036] Step 5, the material is translated to the AGV carrying vehicle body 1; the material is translated to the AGV carrying vehicle body 1 along the flat carrying surface, and the consistent height design realizes unobstructed transfer, completes the last link of loading, and the whole process does not need to adjust the material attitude, improving the operation fluency.

[0037] As another specific embodiment, in step 1, the movable plate 3 driving mechanism is started, the gears 22 on both sides of the movable plate 3 rotate along the racks 21 on both sides of the first placement slot 2, driving the movable plate 3 to move horizontally outward from the placement slot; at the same time, the gears 22 drive the driving wheels 23 in the second placement slot 5 to rotate through the transmission shaft, and the driving wheels 23 drive the driven wheels 24 at the rotating shaft of the turnover plate 4 through the chain or belt 25, so that the turnover plate 4 moves synchronously with the movable plate 3 and turns downward until the turnover plate 4 is in a vertical state. On the one hand, the synchronous action reduces the steps of operating the turnover plate 4 alone, integrates the moving of the movable plate 3 and the turning of the turnover plate 4 into one-time linkage, and greatly improves the efficiency of the early preparation of loading; on the other hand, the rigid engagement of the gears 22 and the racks 21 ensures the smooth movement and accurate positioning of the movable plate 3, and the chain / belt transmission ensures the stability of power transmission, so that the turning angle of the turnover plate 4 is controllable, laying a stable vertical support foundation for the subsequent docking of the lifting plate 7 to the ground and the receiving of materials. At the same time, all transmission components are built-in or integrated in the placement slot, avoiding damage caused by external collision, adapting to the complex operation environment of the intelligent logistics park, and further enhancing the durability and operation convenience of the equipment.
