Description

TECHNICAL FIELD

[0001] The present application relates to the field of carrying devices, in particular to an AGV forklift carrying device. BACKGROUND

[0002] AGV forklifts, as an important logistics equipment, have been widely used in modern warehousing and manufacturing industries. Through an automated navigation system, AGV forklifts can efficiently complete material carrying 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, accuracy, and reliability, especially 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 uses fixed counterweight design to enhance the stability of AGV forklifts, that is, the overall vehicle mass is pre-set to adapt to the maximum load requirement. However, when AGV forklifts carry goods, the goods are loaded inside a box. After the AGV forklift carries the box to the designated location, the AGV forklift also needs to carry the empty box back.

[0004] However, the weight of the goods carried by the AGV forklift may vary, and the overall weight requirement of the AGV forklift will change, while the AGV forklift is pre-set to adapt to the maximum load requirement, which can easily cause energy waste, and the high operating load of the AGV forklift can also cause excessive wear of mechanical parts. SUMMARY

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

[0006] The AGV forklift carrying device provided by the present application adopts the following technical scheme:

[0007] An AGV forklift carrying device, comprising a vehicle body, a cargo 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 on 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 supporting mechanisms are installed inside the counterweight box, the supporting mechanisms are used to support the first counterweight blocks, further comprising a storage tank opened on the ground, the storage tank is used to store the first counterweight blocks, a taking and placing mechanism is installed on the opposite two side walls of the storage tank, and the taking and placing mechanism is used to add or reduce the first counterweight blocks to the counterweight box.

[0008] By adopting the technical scheme, the first counterweight block in the counterweight box can be increased or reduced from the storage groove by the taking and placing mechanism according to actual carrying requirements, so as to adjust the overall weight of the AGV forklift. When heavy objects are carried, the number of the first counterweight block can be increased to improve stability; when light objects are carried, the number of the first counterweight block can be reduced to reduce energy consumption and prolong the service life of the equipment.

[0009] Optionally, the support mechanism comprises a first electromagnet, a first support plate and a first limiting block, an inner wall of the counterweight box is provided with a mounting groove, one side of the first support plate is hinged to an inner bottom wall of the mounting groove, the first electromagnet is mounted to the inner bottom wall of the mounting groove, and the first limiting block is fixedly mounted to 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 mounting groove, and the first electromagnet is used for attracting the first support plate.

[0010] By adopting the technical scheme, in the process that the taking and placing mechanism sends the first counterweight block into the counterweight box, the first counterweight block on the taking and placing mechanism pushes the first support plate to turn upward into the mounting groove, and the first electromagnet can attract the first support plate to keep the first support plate in the mounting groove. Before the taking and placing mechanism puts the first counterweight block into the counterweight box and the taking and placing mechanism retreats, the first electromagnet releases the first support plate, and the first support plate turns downward to abut against the circumferential side of the first counterweight block. Then, when the taking and placing mechanism retreats, the first counterweight block descends under the action of gravity, and the first support plate further turns downward to support below the first counterweight block, thereby facilitating the addition of the first counterweight block into the counterweight box.

[0011] Optionally, the first electromagnet is fixedly mounted with a plug block, the plug block is telescopically mounted to the inner bottom wall of the mounting groove, the plug block is gradually lowered from one side close to the first electromagnet to the other side to be obliquely arranged, the first electromagnet is further used for attracting the circumferential wall of the first counterweight block, and the circumferential wall of the first counterweight block is provided with a plug groove for the first electromagnet and the plug block to enter.

[0012] By adopting the technical scheme, when the first counterweight block is put into the counterweight box, the first electromagnet is started, the first electromagnet attracts the first counterweight block, so that the first electromagnet and the plug block are inserted into the plug groove. The first counterweight block is supported by the plug block, thereby improving the stability of the first counterweight block in the counterweight box. After the first electromagnet is turned off, the plug block is automatically pulled out of the plug groove under the action of the inclined guide and gravity.

[0013] Optionally, the bottom side of the first counterweight block is provided with a limiting groove for the separation block to enter, and the depth of the limiting groove is smaller than the thickness of the separation block in the height direction.

[0014] By adopting the technical scheme, the limit groove is arranged at the bottom of the first counterweight block, the limit groove can accommodate the partition block, the adjacent first counterweight blocks can be positioned through the cooperation of the partition block and the limit groove, and horizontal movement or tilting of the first counterweight blocks in the counterweight box is prevented. Meanwhile, since the depth of the limit groove is less than the height of the partition block, space is left between the adjacent two first counterweight blocks for the support mechanism to support.

[0015] Optionally, the taking and placing mechanism comprises 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 in the driving box in an up-down manner, the body of the motor is fixedly installed on the bottom side of the driving box, the rotating shaft of the motor is screwed through the driving plate, the mounting block is fixedly installed on the side wall of the driving plate, the side wall of the driving box is provided with a sliding opening for the mounting block to slide up and down, and the second support plate is connected with the mounting block.

[0018] By adopting the technical scheme, the hinge between the second support plate and the mounting block is realized, and the stability of the second support plate in the horizontal state is ensured through the second limiting block, so as to facilitate the second support plate to support the first counterweight block. Meanwhile, the second support plate is attracted by the second electromagnet on the driving plate, so as to facilitate the second support plate to be turned up.

[0019] Optionally, a cover plate is hinged to the inner wall of the groove opening, one side of the cover plate is fixedly installed with a third limiting block, and the third limiting block is located below the cover plate and abuts against the inner side wall of the storage groove when the cover plate is horizontal.

[0020] By adopting the technical scheme, the cover plate can effectively prevent dust and impurities from entering the storage groove, and protect the stored first counterweight blocks from being polluted or damaged.

[0021] Optionally, the inner top wall of the drive box is provided with a fixed pulley, the fixed pulley is provided with a pull rope, one end of the pull rope is fixedly connected with the top surface of the drive plate, the other end of the pull rope is fixedly provided with a second counterweight, the second counterweight is liftingly installed in the interior of the drive box, and the drive plate is provided with an avoiding opening through which the second counterweight passes.

Meanwhile, the design of the avoiding opening ensures that the movements of the drive plate and the second counterweight do not interfere with each other, and the stability of the structure in operation is ensured.

[0023] Optionally, the side wall of the drive plate and the side wall of the second counterweight are both fixedly provided with a guide block, and the inner wall of the drive box is provided with a guide groove in which the guide block slidingly moves.

[0025] Optionally, the side wall of the vehicle body is fixedly provided with an anti-collision frame.

[0026] By adopting the above technical scheme, the fixed installation of the anti-collision frame on the side wall of the vehicle body can effectively reduce the damage of the AGV forklift caused by accidental collision in the operation process, and improve the overall durability and safety of the equipment.

DETAILED DESCRIPTION

[0040] The following will be described in detail below with reference to the accompanying drawings. Figures 1-8 The present application will be further described in detail. Embodiment 1

[0041] The present application discloses an AGV forklift carrying device.

[0042] Reference will be made to Figure 1 An AGV forklift carrying device, comprising a vehicle body 1, a 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 is navigated by the laser navigator 3 to move to a position for loading and unloading articles, the fork 2 enters the lower side of the articles. Then the vehicle body 1 drives the fork 2 to lift the articles for carrying.

[0043] The peripheral wall of the vehicle body 1 is fixedly provided with an anti-collision frame 4. The anti-collision frame 4 can effectively reduce the damage caused by accidental collision during the operation of the AGV forklift, and improve the overall durability and safety of the equipment.

[0044] With reference to Figure 1 , Figure 2 , the bottom side of the vehicle body 1 is fixedly embedded with a counterweight box 5, 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 in or taken out from the opening at the bottom side of the counterweight box 5.

[0045] With reference to Figure 2 , Figure 3 , the counterweight box 5 is internally provided with a support mechanism 7. In the embodiment of the application, the support mechanism 7 is arranged in multiple layers along the peripheral side of the counterweight box 5. The support mechanism 7 has multiple layers in the height direction.

[0046] The top side of the first counterweight block 6 is fixedly provided with a partition block 8, and the bottom side of the first counterweight block 6 is provided with a limiting groove 9 for the partition block 8 to enter, the depth of the limiting groove 9 being 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, thereby facilitating the alignment of each first counterweight block 6. At the same time, the partition block 8 leaves a space between the adjacent two first counterweight blocks 6 for the support mechanism 7 to support.

[0047] With reference 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. The inner wall of the counterweight box 5 is provided with a mounting groove 10, and the first electromagnet 71 is fixedly embedded in the inner bottom wall of the mounting groove 10. One side of the first support plate 72 is hinged to the inner bottom wall of the mounting groove 10, so that the first support plate 72 can be flipped up and down. When the first support plate 72 is flipped down to be horizontal, the first support plate 72 is below the first counterweight block 6, thereby facilitating the first support plate 72 to support the first counterweight block 6. When the first support plate 72 is flipped up to enter the inside of the mounting groove 10, the first counterweight block 6 inside the counterweight box 5 lacks support, thereby facilitating the first counterweight block 6 to be taken out of the counterweight box 5.

[0048] The first electromagnet 71 is used to attract the first support plate 72. When the first support plate 72 is flipped up to enter the inside of the mounting 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 mounting groove 10.

[0049] The first limiting block 73 is fixedly installed on one side of the first support plate 72, and when the first support plate 72 is horizontal, the first limiting block 73 is below the first support plate 72 and abuts against the inner bottom wall of the mounting groove 10, thereby limiting the rotation angle of the first support plate 72, and facilitating the first support plate 72 to support the first counterweight block 6.

[0050] Referring to Figure 4 , Figure 5 , the storage tank 11 is arranged on the ground and used for storing the first counterweight 6 for replacement by the AGV forklift. In the embodiment, the storage tank 11 can be arranged at the position where the articles are loaded and unloaded.

[0051] Referring to Figure 5 , Figure 6 , the opposite sidewalls of the storage tank 11 are provided with the taking and placing mechanism 12, which comprises a driving box 121, a motor 122, a driving plate 123, a mounting block 124 and a second supporting plate 125. The driving box 121 is fixedly arranged on the inner sidewall of the storage tank 11. The peripheral sidewall of the driving plate 123 is fixedly provided with a guide block 13, and the inner wall of the driving box 121 is provided with a guide groove 14 for the lifting and sliding of the guide block 13, so that the driving plate 123 is conveniently arranged inside the driving box 121 through the cooperation of the guide block 13 and the guide groove 14.

[0052] The body of the motor 122 is fixedly arranged on the bottom side of the driving box 121, and the rotating shaft of the motor 122 is screwed through the driving plate 123. The motor 122 drives the driving plate 123 to lift when it is started. The mounting block 124 is fixedly arranged on the sidewall of the driving plate 123, and the sidewall of the driving box 121 is provided with a sliding opening for the lifting and sliding of the mounting block 124. One side of the second supporting plate 125 is hingedly connected to the mounting block 124, so that the second supporting plate 125 can be flipped up and down.

[0053] One side of the second supporting plate 125 is fixedly provided with a second limiting block 15, which is located below the second supporting plate 125 and abuts against the sidewall of the driving box 121 when the second supporting plate 125 is horizontal, so as to limit the downward rotation angle of the second supporting plate 125. The top surface of the driving plate 123 is fixedly provided with a second electromagnet 16, which is used for attracting the second supporting plate 125.

[0054] The motor 122 is started to lift the driving plate 123. The driving plate 123 drives the second supporting plate 125 to lift through the mounting block 124. When it is needed to send the first counterweight 6 from the storage tank 11 into the counterweight box 5, the first electromagnet 71 releases the second supporting plate 125, and the second supporting plate 125 abuts against the peripheral side of the first counterweight 6. Then the driving plate 123 is lowered, and after the second supporting plate 125 continues to flip down and enters between the adjacent two first counterweights 6, the driving plate 123 is lifted. The second supporting plate 125 is blocked by the first counterweight 6 and continues to rotate downward. When the second limiting block 15 abuts against the sidewall of the driving box 121, the second supporting plate 125 stops rotating upward, and then the second supporting plate 125 drives the first counterweight 6 to lift, so as to conveniently send the first counterweight 6 from the storage tank 11 into the counterweight box 5.

[0055] The storage tank 11 is hinged with a cover plate 17 on the inner wall of the slot, one side of the cover plate 17 is fixedly installed with a third limiting block 18, the third limiting block 18 is below the cover plate 17 when the cover plate 17 is horizontal and abuts against the inner side wall of the storage tank 11. The cover plate 17 is used to block the storage tank 11, thereby playing a dustproof role, and reducing the situation that the AGV forklift and the staff fall into the inside of the storage tank 11.

[0056] The implementation principle of the AGV forklift carrying device in the embodiment of the application is that a deployment system generally deploys multiple AGV forklifts to carry. Meanwhile, the deployment system records basic information such as the weight and size of the to-be-carried articles. In the application, the deployment system also records the number of the first counterweight blocks 6 remaining in the inside of the storage tank 11 and the number of the first counterweight blocks 6 remaining in the inside of the counterweight box 5 of each AGV forklift. The deployment system is built-in with a counterweight comparison table, and the counterweight comparison table corresponds to the number of the first counterweight blocks 6 required for different article weight ranges.

[0057] The deployment system queries the counterweight comparison table to obtain a counterweight requirement according to the weight of the to-be-carried articles, and the counterweight requirement is the number of the first counterweight blocks 6 required.

[0058] If the number of the first counterweight blocks 6 in the inside of the counterweight box 5 of the AGV forklift is equal to the counterweight requirement, the deployment system issues an instruction to the AGV forklift, and the AGV forklift moves to the article loading and unloading position to load and unload through the laser navigator 3 after receiving the instruction.

[0059] If the number of the first counterweight blocks 6 in the inside of the counterweight box 5 of the AGV forklift is greater than the counterweight requirement, the deployment system issues an instruction to the AGV forklift, and the AGV forklift moves to the article loading and unloading position through the laser navigator 3 after receiving the instruction. Then the first counterweight blocks 6 in the inside of the counterweight box 5 are taken out through the taking and placing mechanism 12.

[0060] If the number of the first counterweight blocks 6 in the inside of the counterweight box 5 of the AGV forklift is less than the counterweight requirement, the deployment system issues an instruction to the AGV forklift, and the AGV forklift moves to the article loading and unloading position through the laser navigator 3 after receiving the instruction. Then the number of the first counterweight blocks 6 in the inside of the counterweight box 5 is increased through the taking and placing mechanism 12.

[0061] When the first counterweight blocks 6 in the inside of the counterweight box 5 are taken and placed through the taking and placing mechanism 12, the deployment system obtains a first counterweight number by subtracting the number of the existing first counterweight blocks 6 from the maximum number of the first counterweight blocks 6 that can be stored in the counterweight box 5, and obtains a second counterweight number by adding a preset compensation number to the first counterweight number.

[0062] The dispensing system starts the motor 122 to move the second support plate 125 to the position where the number of the first counterweights 6 inside the storage tank 11 is one more than the second counterweight number. Then the dispensing system turns off the second electromagnet 16, and the second electromagnet 16 releases the second support plate 125, which flips down and abuts the circumferential side of the first counterweight 6.

[0063] After the second support plate 125 flips down and abuts the circumferential side of the first counterweight 6, the motor 122 drives the second support plate 125 to rise, and because there is a gap between the adjacent two first counterweights 6 separated by the partition 8, the second support plate 125 enters between the adjacent two first counterweights 6. Then the second support plate 125 continues to rise and takes out the first counterweights 6 equal in number to the second counterweight number from the storage tank 11 and into the counterweight box 5.

[0064] When the taking and placing mechanism 12 sends the first counterweight 6 into the counterweight box 5, the taking and placing mechanism 12 lifts each first counterweight 6 inside the counterweight box 5. After each first counterweight 6 inside the counterweight box 5 is lifted, the first support plate 72 is pushed by the first counterweight 6, and the first support plate 72 flips up and enters the installation tank 10. The first electromagnet 71 of the layer counted from top to bottom to the number of the counterweight requirement remains closed, and the first electromagnet 71 of the remaining layers is opened, so that the first support plate 72 remains in the installation tank 10. Then the second support plate 125 of the taking and placing mechanism 12 descends and returns to the inside of the storage tank 11.

[0065] When the taking and placing mechanism 12 returns to the storage tank 11, each first counterweight 6 inside the counterweight box 5 is lowered by gravity, and the first support plate 72 not attracted by the first electromagnet 71 flips down and enters between the adjacent two first counterweights 6 for support, and the remaining first counterweights 6 not supported by the first support plate 72 return to the inside of the storage tank 11 with the taking and placing mechanism 12. The number of the first counterweights 6 inside the counterweight box 5 is increased or decreased, and the adjustment is completed, thereby facilitating the adjustment of the weight of the AGV forklift.

[0066] For factory-produced goods, only the weight changes when producing different goods. In the process of continuously carrying the same goods, only the counterweight of each AGV forklift is adjusted at the beginning of carrying to adapt to the weight of the goods plus the box, thereby playing a role in energy saving and prolonging the service life of the mechanical parts of the AGV forklift. Then the counterweight of the AGV forklift is adjusted again when carrying different goods subsequently. When the AGV forklift carries factory-produced goods, a storage tank 11 is provided at both the position where the goods are loaded and the position where the goods are unloaded to adjust the weight of the AGV forklift, or only one of the position where the goods are loaded and the position where the goods are unloaded is provided with a storage tank 11 to adjust the weight of the AGV forklift.

[0067] For the goods to be transported by logistics, the weight and volume of the goods are easy to change, and the size of the box for loading the goods will also change accordingly. Therefore, the storage tank 11 is provided at the loading position and the unloading position to adjust the weight of the AGV forklift. The AGV forklift adjusts the counterweight once when it lifts the goods from the loading position, and adjusts the counterweight again when it unloads the goods and lifts the empty box at the unloading position, thereby achieving energy saving and prolonging the service life of the mechanical parts of the AGV forklift.

[0068] If the number of first counterweight blocks 6 inside the storage tank 11 at the loading position is small, the matching system matches the AGV forklift with idle and the weight of the AGV forklift is greater than or equal to the weight of the goods to be transported, and the AGV forklift reduces the counterweight, thereby increasing the number of first counterweight blocks 6 inside the storage tank 11 at the loading position.

[0069] If the number of first counterweight blocks 6 inside the storage tank 11 at the loading position is large, the matching system matches the AGV forklift with idle and the weight of the AGV forklift is less than or equal to the weight of the goods to be transported, and the AGV forklift increases the counterweight, thereby reducing the number of first counterweight blocks 6 inside the storage tank 11 at the loading position.

[0070] The size and weight of the goods are different, and the box for loading the goods is also different. After the AGV forklift transports the box containing goods to the unloading position, the AGV forklift needs to transport another empty box to return. The unloading position has a plurality of boxes of different sizes.

[0071] If the number of first counterweight blocks 6 inside the storage tank 11 at the unloading position is small, the matching system makes the AGV forklift transport the empty box that matches the weight of the AGV forklift, or the AGV forklift transports the empty box that needs a small counterweight.

[0072] If the number of first counterweight blocks 6 inside the storage tank 11 at the unloading position is large, the matching system makes the AGV forklift transport the empty box that matches the weight of the AGV forklift, or the AGV forklift transports the empty box that needs a large counterweight.

[0073] By selecting different sizes of empty boxes for the AGV forklift to transport according to the number of first counterweight blocks 6 at the unloading position, the change speed of the number of first counterweight blocks 6 at the unloading position is slowed down. When the number of first counterweight blocks 6 at the unloading position exceeds the predetermined number, the matching system controls an AGV forklift to transport the first counterweight blocks 6 at the unloading position to the loading position.

[0074] By adjusting the counterweight of the AGV forklift, the AGV forklift increases the counterweight when transporting the box containing goods, thereby improving the stability of the AGV forklift in transporting the goods. When the AGV forklift transports the empty box, the AGV forklift reduces the counterweight, thereby achieving energy saving and prolonging the service life of the mechanical parts of the AGV forklift. Embodiment 2

[0075] The embodiment of the present application discloses an AGV forklift carrying device.

[0076] With reference to Figure 7 , Figure 8 The AGV forklift carrying device of the embodiment of the present application is different from the embodiment 1 in that a fixed pulley 19 is mounted on the inner top wall of the drive box 121, and the fixed pulley 19 is wound with a pull rope 20. One end of the pull rope 20 is fixedly connected with the top surface of the drive plate 123, and the other end of the pull rope 20 is fixedly installed with a second counterweight 21. The second counterweight 21 is also installed with the guide block 13 to slide up and down in the drive box 121. The drive plate 123 is provided with an avoiding opening 22 through which the second counterweight 21 passes. The second counterweight 21 exerts an upward pulling force on the drive plate 123, thereby reducing the driving force required by the motor 122.

[0077] The first electromagnet 71 is fixedly installed with an insertion block 23, the insertion block 23 is telescopically installed on the inner bottom wall of the installation slot 10, and the insertion block 23 gradually decreases from one side close to the first electromagnet 71 to the other side, and is inclined. Influenced by the inclination of the insertion block 23, the insertion block 23 will retract into the installation slot 10 under the action of gravity. The circumferential wall of the first counterweight 6 is provided with an insertion slot 24 through which the first electromagnet 71 and the insertion block 23 enter. After the first electromagnet 71 is electrified, the first electromagnet 71 generates a magnetic force to attract the first counterweight 6, so that the first electromagnet 71 slides to the first counterweight 6 and is inserted into the insertion slot 24.

[0078] The implementation principle of the AGV forklift carrying device of the embodiment of the present application is that when the first support plate 72 supports the first counterweight 6, the first electromagnet 71 is started.
