Description

Technical Field

[0001] This application relates to the field of handling devices, and particularly to an AGV forklift handling device. Background Art

[0002] As an important logistics equipment, AGV forklifts have been widely used in modern warehousing and manufacturing. Through the automated navigation system, AGV forklifts can efficiently complete material handling tasks, significantly improving production efficiency and reducing labor costs. With the development of smart factories, AGV forklifts have become an indispensable part due to their flexibility, precision, and reliability, especially showing excellent performance in cargo loading and unloading scenarios, greatly promoting the modernization process of the logistics industry.

[0003] Currently, in order to meet different load requirements, the industry generally adopts a fixed counterweight design to enhance the stability of AGV forklifts, that is, the vehicle mass is preset to adapt to the maximum load demand. However, when an AGV forklift transports an item, the item is placed inside a box. After the AGV forklift transports the box to the designated position, the AGV forklift still has to transport the empty box back.

[0004] However, the weight of the item transported by the AGV forklift may vary, and the weight requirement of the entire AGV forklift will change. Since the vehicle mass of the AGV forklift is preset to adapt to the maximum load demand, it is easy to cause energy waste, and the high operating load of the AGV forklift is also likely to cause excessive wear of mechanical components. Summary of the Invention

[0005] In order to facilitate the adjustment of the weight of the AGV forklift, this application provides an AGV forklift handling device.

[0006] An AGV forklift handling device provided by this application adopts the following technical solutions: An AGV forklift handling device includes a vehicle body. A fork is installed on one side of the vehicle body in a lifting manner. A laser navigator is fixedly installed on the top side of the vehicle body. A counterweight box is fixedly embedded in the bottom side of the vehicle body. The bottom side of the counterweight box has an opening. A plurality of first counterweight blocks are placed inside the counterweight box. A partition block is fixedly installed on the top side of the first counterweight block. A plurality of support mechanisms are installed inside the counterweight box. The support mechanisms are used to support the first counterweight blocks. It also includes a storage groove opened on the ground. The storage groove is used to store the first counterweight blocks. Lifting and placing mechanisms are installed on the opposite side walls of the storage groove. The lifting and placing mechanisms are used to add or subtract the first counterweight blocks to / from the counterweight box.

[0007] By adopting the above technical solution, the first counterweight block in the counterweight box can be increased or decreased from the storage tank through the picking and placing mechanism according to the actual handling requirements, so as to adjust the overall weight of the entire AGV forklift. When handling heavier items, the number of the first counterweight blocks can be increased to improve stability; when handling lighter items, the number of the first counterweight blocks can be decreased to reduce energy consumption and extend the service life of the equipment.

[0008] Optionally, the supporting mechanism includes a first electromagnet, a first support plate and a first limiting block. An installation groove is formed in the inner wall of the counterweight box. One side of the first support plate is hinged to the inner bottom wall of the installation groove. The first electromagnet is installed on the inner bottom wall of the installation groove. The first limiting block is fixedly installed on one side of the first support plate. When the first support plate is horizontal, the first limiting block is located below the first support plate and abuts against the inner bottom wall of the installation groove. The first electromagnet is used to attract the first support plate.

[0009] By adopting the above technical solution, during the process of the picking and placing mechanism sending the first counterweight block into the counterweight box, the first counterweight block on the picking and placing mechanism pushes the first support plate to turn upwards and enter the installation groove. The first electromagnet can adsorb the first support plate to keep the first support plate inside the installation groove. Before the picking and placing mechanism puts the first counterweight block into the counterweight box and the picking and placing mechanism retracts, the first electromagnet releases the first support plate, and the first support plate turns downwards and abuts against the peripheral side of the first counterweight block. Then when the picking and placing mechanism retracts, the first counterweight block drops due to gravity, and the first support plate further turns downwards and enters below the first counterweight block for support, so as to facilitate adding the first counterweight block into the counterweight box.

[0010] Optionally, the first electromagnet is fixedly installed with an insertion block. The insertion block is telescopically installed on the inner bottom wall of the installation groove. The insertion block is inclined to gradually decrease from one side close to the first electromagnet to the other side. The first electromagnet is also used to attract the peripheral side wall of the first counterweight block. A slot for the first electromagnet and the insertion block to enter is formed in the peripheral side wall of the first counterweight block.

[0011] By adopting the above technical solution, when the first counterweight block is put into the counterweight box, the first electromagnet is started, and the first electromagnet attracts the first counterweight block, so that the first electromagnet and the insertion block are inserted into the slot. The insertion block supports the first counterweight block, so as to improve the stability of the first counterweight block inside the counterweight box. After the first electromagnet is turned off, the insertion block is automatically pulled out of the slot under the guidance of the inclination and gravity.

[0012] Optionally, a limiting groove for the partition block to enter is formed in the bottom side of the first counterweight block. The depth of the limiting groove is smaller than the thickness of the partition block in the height direction.

[0013] By adopting the above technical solution, a limiting groove is formed at the bottom of the first counterweight block. This limiting groove can accommodate the partition block, enabling the adjacent first counterweight blocks to be positioned through the cooperation of the partition block and the limiting groove, preventing the first counterweight blocks from moving horizontally or tipping over in the counterweight box. At the same time, since the depth of the limiting groove is less than the height of the partition block, it is convenient to leave a space between two adjacent first counterweight blocks for the support mechanism to support.

[0014] Optionally, the picking and placing mechanism includes a driving box, a motor, a driving plate, a mounting block, and a second support plate. The driving box is fixedly installed on the inner side wall of the storage groove. The driving plate is arranged to move up and down inside the driving box. The body of the motor is fixedly installed on the bottom side of the driving box. The rotating shaft of the motor threadedly penetrates the driving plate. The mounting block is fixedly installed on the side wall of the driving plate. A sliding opening for the mounting block to move up and down and slide is formed on the side wall of the driving box. The second support plate is connected to the mounting block.

[0015] By adopting the above technical solution, a picking and placing mechanism with a high degree of automation is realized. This mechanism uses the motor to drive the rotating shaft to rotate, driving the driving plate to move up and down in the driving box, thereby controlling the movement of the second support plate through the mounting block. This design can accurately adjust the position of the second support plate, facilitating the removal of the first counterweight block from the storage groove and placing it into the counterweight box, improving the flexibility and adaptability of the AGV forklift handling device.

[0016] Optionally, the second support plate is hinged to the mounting block. A second limiting block is fixedly installed on one side of the second support plate. When the second support plate is horizontal, the second limiting block is located below the second support plate and abuts against the side wall of the driving box. A second electromagnet is fixedly installed on the top surface of the driving plate. The second electromagnet is used to attract the second support plate.

[0017] By adopting the above technical solution, the hinge between the second support plate and the mounting block is realized, and the stability of the second support plate when it is in a horizontal state is ensured through the second limiting block, thus facilitating the second support plate to support the first counterweight block. At the same time, the second support plate is attracted by the second electromagnet on the driving plate, facilitating the upward flipping of the second support plate.

[0018] Optionally, a cover plate is hinged to the inner wall of the storage groove at the notch. A third limiting block is fixedly installed on one side of the cover plate. When the cover plate is horizontal, the third limiting block is located below the cover plate and abuts against the inner side wall of the storage groove.

[0019] By adopting the above technical solution, the cover plate can effectively prevent dust and impurities from entering the storage groove, protecting the stored first counterweight blocks from being contaminated or damaged.

[0020] Optionally, a fixed pulley is installed on the inner top wall of the drive box. A pulling rope is wound around the fixed pulley. One end of the pulling rope is fixedly connected to the top surface of the drive plate. The other end of the pulling rope is fixedly installed with a second counterweight. The second counterweight is installed in the drive box in a lifting manner. The drive plate is provided with an avoidance opening for the second counterweight to pass through.

[0021] By adopting the above technical solution, the fixed pulley and the pulling rope are arranged in the drive box and cooperate with the second counterweight, which can reduce the power required for the drive plate to rise, thereby reducing the driving force required by the motor. At the same time, the design of the avoidance opening ensures that the movements between the drive plate and the second counterweight do not interfere with each other, ensuring the stability of the structure operation.

[0022] Optionally, guide blocks are fixedly installed on the peripheral side wall of the drive plate and the side wall of the second counterweight. Guide grooves for the guide blocks to lift and slide are formed on the inner wall of the drive box.

[0023] By adopting the above technical solution, the cooperation between the guide blocks and the guide grooves can effectively improve the stability of the drive plate and the second counterweight during the lifting process, avoid tilting or jamming phenomena, and thus ensure the reliability of the picking and placing mechanism operation.

[0024] Optionally, a collision prevention frame is fixedly installed on the peripheral side wall of the vehicle body.

[0025] By adopting the above technical solution, fixedly installing a collision prevention frame on the peripheral side wall of the vehicle body can effectively reduce the damage caused by accidental collisions during the operation of the AGV forklift, improving the overall durability and safety of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: By arranging a counterweight box at the bottom of the vehicle body and cooperating with the ground storage tank to realize the dynamic increase and decrease of the first counterweight, the overall counterweight of the AGV forklift can be flexibly adjusted according to the weight of different handling items, thereby reducing the occurrence of excessive energy consumption or excessive wear of mechanical components; Through the flip design of the first support plate, it is convenient to select different numbers of first counterweights for lifting, and thus convenient to adjust the counterweight of the AGV forklift; The picking and placing mechanism realizes the automatic transfer of the counterweight from the storage tank to the counterweight box through motor drive and the design of the second support plate, simplifies the operation process and improves the work efficiency.

Detailed implementation manners

[0029] The following further elaborates on the present application in conjunction with the attached Figure 1-8 drawings. Embodiment 1

[0030] Embodiment 1 of the present application discloses an AGV forklift handling device.

[0031] Referring to Figure 1 , an AGV forklift handling device includes a vehicle body 1, a forklift fork 2 is installed on one side of the vehicle body 1 in a lifting manner, and a laser navigator 3 is fixedly installed on the top side of the vehicle body 1. After the AGV forklift moves to the position for loading and unloading items through the navigation of the laser navigator 3, the forklift fork 2 enters below the items. Then the vehicle body 1 drives the forklift fork 2 to lift the items for handling.

[0032] An anti-collision frame 4 is fixedly installed on the peripheral side wall of the vehicle body 1. The anti-collision frame 4 can effectively reduce the damage caused by accidental collisions during the operation of the AGV forklift, and improve the overall durability and safety of the equipment.

[0033] Referring to Figure 1 , Figure 2, a counterweight box 5 is fixedly embedded in the bottom side of the vehicle body 1, and the bottom side of the counterweight box 5 has an opening. A plurality of first counterweight blocks 6 are placed inside the counterweight box 5, and the first counterweight blocks 6 are put into or taken out from the opening at the bottom side of the counterweight box 5.

[0034] Referring to Figure 2 , Figure 3 , a support mechanism 7 is installed inside the counterweight box 5. In the embodiment of the present application, a plurality of support mechanisms 7 are arranged at intervals along the circumferential side of the counterweight box 5 to form a layer. The support mechanism 7 has multiple layers in the height direction.

[0035] A partition block 8 is fixedly installed on the top side of the first counterweight block 6, and a limiting groove 9 for the partition block 8 to enter is opened on the bottom side of the first counterweight block 6. The depth of the limiting groove 9 is less than the thickness of the partition block 8 in the height direction. The partition block 8 enters the inside of the limiting groove 9, so as to facilitate the alignment of each first counterweight block 6. At the same time, the partition block 8 leaves a space between two adjacent first counterweight blocks 6 for the support mechanism 7 to support.

[0036] Referring to Figure 2 , Figure 3 , the support mechanism 7 includes a first electromagnet 71, a first support plate 72 and a first limiting block 73. An installation groove 10 is opened on the inner wall of the counterweight box 5, and the first electromagnet 71 is fixedly embedded in the inner bottom wall of the installation groove 10. One side of the first support plate 72 is hinged to the inner bottom wall of the installation groove 10, so that the first support plate 72 can be turned up and down. When the first support plate 72 is turned downwards to be horizontal, the first support plate 72 is located below the first counterweight block 6, so as to facilitate the first support plate 72 to support the first counterweight block 6. When the first support plate 72 is turned upwards and enters the inside of the installation groove 10, the first counterweight block 6 inside the counterweight box 5 lacks support, so as to facilitate taking out the first counterweight block 6 from the counterweight box 5.

[0037] The first electromagnet 71 is used to attract the first support plate 72. When the first support plate 72 is turned upwards and enters the inside of the installation groove 10, the first electromagnet 71 is started, and the first electromagnet 71 attracts the first support plate 72, so that the first support plate 72 is kept inside the installation groove 10.

[0038] The first limiting block 73 is fixedly installed on one side of the first support plate 72. When the first support plate 72 is horizontal, the first limiting block 73 is located below the first support plate 72 and abuts against the inner bottom wall of the installation groove 10, so as to play a role in restricting the rotation angle of the first support plate 72, and further facilitate the first support plate 72 to support the first counterweight block 6.

[0039] Referring to Figure 4 , Figure 5 , it further includes a storage groove 11 opened on the ground. The storage groove 11 is used to store the first counterweight blocks 6 for replacement by an AGV forklift. In the embodiment of the present application, the storage groove 11 can be opened at the position where goods are loaded and unloaded.

[0040] Refer to Figure 5 、 Figure 6 On opposite side walls of the storage tank 11, a picking and placing mechanism 12 is installed. The picking and placing mechanism 12 includes a driving box 121, a motor 122, a driving plate 123, a mounting block 124, and a second support plate 125. The driving box 121 is fixedly installed on the inner side wall of the storage tank 11. A guiding block 13 is fixedly installed on the peripheral side wall of the driving plate 123, and a guiding groove 14 for the guiding block 13 to lift and slide is formed on the inner wall of the driving box 121. By the cooperation of the guiding block 13 and the guiding groove 14, the driving plate 123 is conveniently arranged to be lifted and lowered inside the driving box 121.

[0041] The body of the motor 122 is fixedly installed on the bottom side of the driving box 121, and the rotating shaft of the motor 122 penetrates through the driving plate 123 in a threaded manner. When the motor 122 is started, the motor 122 drives the driving plate 123 to lift and lower. The mounting block 124 is fixedly installed on the side wall of the driving plate 123, and a sliding opening for the mounting block 124 to lift and slide is formed on the side wall of the driving box 121. One side of the second support plate 125 is hinged to the mounting block 124, so that the second support plate 125 can be turned up and down.

[0042] A second limiting block 15 is fixedly installed on one side of the second support plate 125. When the second support plate 125 is horizontal, the second limiting block 15 is located below the second support plate 125 and abuts against the side wall of the driving box 121, thus playing a role in restricting the downward rotation angle of the second support plate 125. A second electromagnet 16 is fixedly installed on the top surface of the driving plate 123, and the second electromagnet 16 is used to attract the second support plate 125.

[0043] Start the motor 122 to lift and lower the driving plate 123. The driving plate 123 drives the second support plate 125 to lift and lower through the mounting block 124. When it is necessary to send the first counterweight 6 from the storage tank 11 into the counterweight box 5, the first electromagnet 71 releases the second support plate 125, and the second support plate 125 abuts against the periphery of the first counterweight 6. Then the driving plate 123 descends. After the second support plate 125 continues to turn downward and enters between two adjacent first counterweights 6. The driving plate 123 rises. The second support plate 125 is blocked by the first counterweight 6 and continues to turn downward. When the second limiting block 15 abuts against the side wall of the driving box 121, the second support plate 125 stops turning upward. Then the second support plate 125 drives the first counterweight 6 to rise, thus facilitating the sending of the first counterweight 6 from the storage tank 11 into the counterweight box 5.

[0044] A cover plate 17 is hinged to the inner wall of the notch of the storage tank 11. A third limiting block 18 is fixedly installed on one side of the cover plate 17. When the cover plate 17 is horizontal, the third limiting block 18 is located below the cover plate 17 and abuts against the inner side wall of the storage tank 11. The cover plate 17 is used to seal the storage tank 11, so as to play a role in dust prevention, and at the same time reduce the situation that the AGV forklift and the staff fall into the storage tank 11.

[0045] The implementation principle of an AGV forklift handling device according to an embodiment of the present application is as follows: Generally, a dispatching system is used to dispatch multiple AGV forklifts for handling. At the same time, the dispatching system will record basic information such as the weight and size of the items to be transported. In the present application, the dispatching system also records the number of the first counterweight blocks 6 remaining inside the storage tank 11 and the number of the first counterweight blocks 6 remaining inside the counterweight box 5 of each AGV forklift. The dispatching system is built-in with a counterweight comparison table, and the counterweight comparison table is the number of the first counterweight blocks 6 required for different weight ranges of items.

[0046] The dispatching system queries the counterweight comparison table according to the weight of the item to be transported to obtain the counterweight requirement, and the counterweight requirement is the number of the first counterweight blocks 6 required.

[0047] If the number of the first counterweight blocks 6 inside the counterweight box 5 of the AGV forklift is equal to the counterweight requirement, the dispatching system sends an instruction to the AGV forklift. After receiving the instruction, the AGV forklift moves to the position for loading and unloading items through the laser navigator 3 for loading and unloading.

[0048] If the number of the first counterweight blocks 6 inside the counterweight box 5 of the AGV forklift is greater than the counterweight requirement, the dispatching system sends an instruction to the AGV forklift. After receiving the instruction, the AGV forklift moves to the position for loading and unloading items through the laser navigator 3. Then, the first counterweight blocks 6 inside the counterweight box 5 are taken out through the picking and placing mechanism 12.

[0049] If the number of the first counterweight blocks 6 inside the counterweight box 5 of the AGV forklift is less than the counterweight requirement, the dispatching system sends an instruction to the AGV forklift. After receiving the instruction, the AGV forklift moves to the position for loading and unloading items through the laser navigator 3. Then, the number of the first counterweight blocks 6 is increased inside the counterweight box 5 through the picking and placing mechanism 12.

[0050] When the first counterweight blocks 6 inside the counterweight box 5 are picked and placed through the picking and placing mechanism 12, the dispatching system obtains the first counterweight quantity by subtracting the existing number of the first counterweight blocks 6 from the maximum number of the first counterweight blocks 6 that the counterweight box 5 can store, and the second counterweight quantity is obtained by adding the preset compensation quantity to the first counterweight quantity.

[0051] The dispensing system starts the motor 122 to move the second support plate 125 to a position inside the storage tank 11 where the number of the first counterweight blocks 6 counted from top to bottom reaches one more than the number of the second counterweights. Then the dispensing system turns off the second electromagnet 16. The second electromagnet 16 releases the second support plate 125, and after the second support plate 125 flips downward, it abuts against the periphery of the first counterweight block 6.

[0052] After the second support plate 125 flips downward and abuts against the periphery of the first counterweight block 6, the motor 122 drives the second support plate 125 to rise. Since there is a gap between adjacent two first counterweight blocks 6 separated by the partition block 8, the second support plate 125 will enter the gap between adjacent two first counterweight blocks 6. Then when the second support plate 125 continues to rise, it will take out the first counterweight blocks 6 with the number equal to the number of the second counterweights from the storage tank 11 and into the counterweight box 5.

[0053] When the picking and placing mechanism 12 sends the first counterweight block 6 into the counterweight box 5, the picking and placing mechanism 12 jacks up each first counterweight block 6 inside the counterweight box 5. After each first counterweight block 6 inside the counterweight box 5 is jacked up, the first support plate 72 is pushed by the first counterweight block 6, and the first support plate 72 flips upward into the installation groove 10. The first electromagnet 71 of the layer reaching the counterweight requirement counted from top to bottom remains closed, and the first electromagnets 71 of the remaining layers are turned on, so as to keep the first support plate 72 inside the installation groove 10. Then the second support plate 125 of the picking and placing mechanism 12 descends and returns to the inside of the storage tank 11.

[0054] When the picking and placing mechanism 12 returns to the storage tank 11, each first counterweight block 6 inside the counterweight box 5 descends due to gravity. The first support plate 72 not attracted by the first electromagnet 71 flips downward and enters the position behind and supporting two adjacent first counterweight blocks 6, and the remaining first counterweight blocks 6 not supported by the first support plate 72 return to the inside of the storage tank 11 with the picking and placing mechanism 12. The adjustment of the number of the first counterweight blocks 6 inside the counterweight box 5 is completed, thus facilitating the adjustment of the weight of the AGV forklift.

[0055] For the items produced by the factory, only the weight will change when different items are produced. During the continuous handling of the same item, only at the beginning of the handling, the counterweight of each AGV forklift is adjusted to match the weight of the item plus the box, so as to play an energy-saving role and extend the service life of the mechanical components of the AGV forklift. Then when handling different items subsequently, the counterweight of the AGV forklift is adjusted again. When the AGV forklift is handling the items produced by the factory, storage tanks 11 are provided at both the item loading position and the item unloading position to adjust the weight of the AGV forklift, or only one of the item loading position and the item unloading position is provided with a storage tank 11 to adjust the weight of the AGV forklift.

[0056] For the items to be carried in logistics transportation, the weight and volume of general items are prone to change, and the size of the boxes used to contain the items will also change accordingly. Then, storage slots 11 are opened at both the item loading position and the item unloading position to adjust the weight of the AGV forklift. The AGV forklift adjusts the counterweight once when lifting the item from the item loading position, and adjusts the counterweight again when unloading the item and lifting the empty box at the item unloading position, so as to play an energy-saving role and extend the service life of the mechanical components of the AGV forklift.

[0057] If the number of the first counterweight blocks 6 inside the storage slot 11 at the item loading position is small, the dispatching system matches an idle AGV forklift with a counterweight greater than or equal to the weight of the item to be carried for transportation, and the AGV forklift reduces the counterweight, thereby increasing the number of the first counterweight blocks 6 inside the storage slot 11 at the item loading position.

[0058] If the number of the first counterweight blocks 6 inside the storage slot 11 at the item loading position is large, the dispatching system matches an idle AGV forklift with a counterweight less than or equal to the weight of the item to be carried for transportation, and the AGV forklift increases the counterweight, thereby reducing the number of the first counterweight blocks 6 inside the storage slot 11 at the item loading position.

[0059] The sizes and weights of the items are different, and the boxes used to contain the items are also different. After the AGV forklift transports the box containing the item to the item unloading position, the AGV forklift needs to transport another empty box back. There are multiple boxes of different sizes at the item unloading position.

[0060] If the number of the first counterweight blocks 6 inside the storage slot 11 at the item unloading position is small, the dispatching system allows the AGV forklift to transport an empty box that matches the counterweight of the AGV forklift, or the AGV forklift transports an empty box that requires a small counterweight.

[0061] If the number of the first counterweight blocks 6 inside the storage slot 11 at the item unloading position is large, the dispatching system allows the AGV forklift to transport an empty box that matches the counterweight of the AGV forklift, or the AGV forklift transports an empty box that requires a large counterweight.

[0062] By having the AGV forklift select empty boxes of different sizes for transportation according to the number of the first counterweight blocks 6 at the item unloading position, the change speed of the number of the first counterweight blocks 6 at the item unloading position is delayed. When the number of the first counterweight blocks 6 at the item unloading position exceeds the predetermined number, the dispatching system controls an AGV forklift to transport the first counterweight blocks 6 at the item unloading position to the item loading position.

[0063] By adjusting the counterweight of the AGV forklift, when the AGV forklift transports the box containing the item, the counterweight of the AGV forklift is increased, thereby improving the stability of the AGV forklift in transporting the item. When the AGV forklift transports the empty box, the increased counterweight of the AGV forklift is reduced, so as to play an energy-saving role and extend the service life of the mechanical components of the AGV forklift. Embodiment 2

[0064] An embodiment of the present application discloses an AGV forklift handling device.

[0065] Referring to Figure 7 、 Figure 8 An AGV forklift handling device according to an embodiment of the present application is different from that in Embodiment 1 in that a fixed pulley 19 is installed on the inner top wall of the drive box 121, and a pulling rope 20 is wound around the fixed pulley 19. One end of the pulling rope 20 is fixedly connected to the top surface of the drive plate 123, and a second counterweight 21 is fixedly installed at the other end of the pulling rope 20. A guide block 13 is also installed on the second counterweight 21 to perform lifting and sliding inside the drive box 121. The drive plate 123 is provided with an avoidance opening 22 for the second counterweight 21 to pass through. The second counterweight 21 exerts an upward pulling force on the drive plate 123, thereby reducing the driving force required by the motor 122.

[0066] An insertion block 23 is fixedly installed on the first electromagnet 71. The insertion block 23 is telescopically installed on the inner bottom wall of the installation groove 10, and the insertion block 23 gradually decreases from one side close to the first electromagnet 71 to the other side and is inclined. Affected by the inclination of the insertion block 23, the insertion block 23 will retract into the installation groove 10 under the drive of gravity. A slot 24 for the first electromagnet 71 and the insertion block 23 to enter is provided on the peripheral side wall of the first counterweight 6. After the first electromagnet 71 is energized, the first electromagnet 71 generates a magnetic force to attract the first counterweight 6, so that the first electromagnet 71 slides towards the first counterweight 6 and then inserts into the slot 24.

[0067] The implementation principle of an AGV forklift handling device according to an embodiment of the present application is as follows: When the first support plate 72 supports the first counterweight 6, the first electromagnet 71 is started. The first electromagnet 71 moves towards the periphery of the first counterweight 6, so that the first electromagnet 71 and the insertion block 23 are inserted into the slot 24, thereby playing a role in fixing and supporting the first counterweight 6.

[0068] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
