[0021] Example 1, such as Figure 1-2 As shown, the multi-functional AGV forklift includes a frame 1. The bottom of the frame 1 is equipped with motor-driven wheels. A first servo motor 4 is mounted on the top of the frame 1. A lead screw 5 is mounted on the output end of the first servo motor 4 via a coupling. The upper and lower ends of the lead screw 5 rotate on the inner wall of the frame 1. A support rod 6 is threaded onto the outer surface of the lead screw 5 and slides on the outer surface of the frame 1. A laser scanner is mounted on the top of the support rod 6. Two forks 7 are fixedly connected to one side of the support rod 6. A clamping device 2 is mounted on the top of the frame 1 to further secure the position of the item box on the forks 7. When the AGV forklift is working, the laser scanner on the top of the frame 1 emits a laser beam, which is reflected after contact with the building in the environment and received by the receiving radar inside the laser scanner. The calculation... The distance to the obstacle is controlled by the drive device inside the frame 1, which moves the moving wheels to drive the vehicle body. According to the pre-designed route, it moves to the side of the item box and slowly moves when it gets close to the item box, so that the fork 7 enters the bottom of the item box. Then, the first servo motor 4 at the top of the frame 1 drives the lead screw 5 to rotate, so that the support rod 6 moves upward on the outer surface of the lead screw 5 to lift the item box. Then, the vehicle body moves according to the predetermined route to transport the item box to the unloading point. The first servo motor 4 is operated to control the lead screw 5 to rotate, so that the support rod 6 moves downward on the outer surface of the lead screw 5 and the outer surface of the frame 1, so that the fork 7 is misaligned with the placement rack of the item box. After the fork 7 descends to the bottom of the placement rack, the bottom of the item box contacts the placement rack and enters the surface of the placement rack to complete the unloading.
[0022] Reference Figure 1-5As shown in this embodiment: the clamping device 2 includes a shaft 22, which rotates on one side of the top of the frame 1. A grooved rod 23 is fixedly connected to the outer surface of the shaft 22, and a sliding rod 25 is slidably connected to the inner wall of the grooved rod 23. A rotating shaft 26 is fixedly connected to one end of the sliding rod 25, and a pressure plate 28 is rotatably connected to the outer surface of the rotating shaft 26. A coil spring 27 is provided at one end of the rotating shaft 26, and both ends of the coil spring 27 are fixedly connected to one side of the rotating shaft 26 and one side of the inner wall of the pressure plate 28, respectively. A second servo motor 21 is provided on one side of the top of the frame 1, and the output end of the second servo motor 21 is fixedly connected to one end of the shaft 22 through a coupling. A first electric push rod 24 is provided on one side of the grooved rod 23, and the output rod of the first electric push rod 24 is fixedly connected to one side of the sliding rod 25. By setting the pressure plate 28, when using an AGV forklift, after the item box is moved to the outer surface of the fork 7 by the fork 7, it can be transported. The second servo motor 21 controls the shaft 22 to drive the groove rod 23 and slide rod 25 to rotate downwards. During the rotation, the first electric push rod 24 extends and pushes the slide rod 25 to slide on the inner wall of the groove rod 23, causing the pressure plate 28 to descend. One end of the pressure plate 28 contacts the top of the item box. After one end of the pressure plate 28 contacts the item, the entire plate rotates on the outer surface of the rotating shaft 26 and deforms the coil spring 27, so that the bottom end of the pressure plate 28 fits against the top of the item box. Then the operation of the second servo motor 21 and the first electric push rod 24 stops, leaving the pressure plate 28 pressing on the top of the item box. During the movement of the frame 1, the pressure plate 28 pressing on the top of the item box further restricts the position of the item box on the fork arm 7, minimizing the problem of the item box falling off the fork arm 7 due to inertia when the forklift is driving, turning, or braking, thus improving the stability of the forklift during use.
[0023] Reference Figure 2 , Figure 4 and Figure 5 As shown in this embodiment: the bottom end of the pressure plate 28 is rotatably connected to several rotating rollers 211, which are rubber rollers. When the pressure plate 28 is pressed against the top of the item box, the rubber rollers 211 are pressed tightly. When the item box is placed on the shelf and the item box is unloaded, the pressure plate 28 rises a certain distance to release the pressure on the rollers 211 and the top of the item box contacts the rollers 211. When the fork 7 moves away from the item box, the rollers 211 will roll on the top of the item box. The position of the item box is continuously restricted by the pressure plate 28, which improves the stability when unloading the item box. The top of the pressure plate 28 is provided with a second electric push rod 29. The output rod of the second electric push rod 29 is fixedly connected to the pressure rod 210. After the bottom end of the pressure plate 28 is attached to the top of the item box, the second electric push rod 29 can be operated to extend and control one end of the pressure rod 210 to press against the top of the pressure plate 28, further restricting the position of the item box on the fork 7 and preventing the item box from rolling under the rollers 211.
[0024] Reference Figure 2 , Figure 4 and Figure 5 As shown in this embodiment: a rubber disc 212 is fixedly connected to one end of the shaft 22. One side of the disc 212 is attached to the top side of the frame 1. By setting the rubber disc 212, the friction between the shaft 22 and the frame 1 can be increased, making the shaft 22 more stable when it drives the groove rod 23 and the pressure plate 28 to rotate.
[0025] Reference Figure 1-3 As shown in this embodiment: a buffer device 3 is provided at one end of the fork lever 7. The buffer device 3 includes a rubber rod 35. Two rectangular rods 34 are fixedly connected to one side of the rubber rod 35. Two slots 31 are opened at one end of the fork lever 7. When using a forklift, the two rectangular rods 34 on one side of the rubber rod 35 can be inserted into the slots 31 at one end of the two fork levers 7 respectively, and the rubber rod 35 is installed at one end of the fork lever 7. When the fork lever 7 collides with an object at one end during loading and unloading, the rubber rod 35 can block the collision and reduce the damage caused by the collision. A spring 32 is provided inside the slot 31. A stop block 33 is provided at one end of the spring 32. The two ends of the spring 32 are respectively connected to one side of the stop block 33 and the inner wall of the slot 31. One side is fixedly connected. When the rectangular rod 34 is inserted into the slot 31, one end of the rectangular rod 34 contacts the surface of the stop block 33. When one end of the rubber rod 35 is impacted and squeezed, it will push the rectangular rod 34 to slide into the slot 31, apply pressure to the stop block 33 and compress the spring 32. The spring 32 can further buffer the impact on one end of the rubber rod 35 and the fork 7. Several protrusions 36 are fixedly connected to the upper and lower sides of the rectangular rod 34. The protrusions 36 are linearly distributed on the outer surface of the rubber rod 35. Pinching the protrusions 36 on the upper and lower sides of the rubber rod 35 can increase the friction between the hand and the surface of the rubber rod 35 when pinching the rubber rod 35, making it easier to remove the rubber rod 35 and less likely to slip.
[0026] Working principle: When using the forklift, two rectangular rods 34 on one side of a rubber rod 35 can be inserted into the slot 31 at one end of each of the two forks 7, and the rubber rod 35 is installed at one end of the forklift 7. When the AGV forklift is working, the laser scanner at the top of the frame 1 emits a laser, which is reflected after contact with buildings in the environment and received by the receiving radar inside the laser scanner. The distance to obstacles is calculated, and the drive device inside the frame 1 controls the movement of the moving wheels to move the vehicle body. According to the pre-designed route, it moves to the side of the item box, and when it gets close to the item box, it moves slowly so that the forklift 7 enters the bottom of the item box. Then, the first servo motor 4 at the top of the frame 1 drives the lead screw 5 to rotate, so that the support rod 6 moves upward on the outer surface of the lead screw 5 to lift the item box. Then, the second servo motor 21 controls the shaft 22 to drive the groove rod 23 and the slide rod 25 to rotate downward. During the rotation, the first electric push rod 24 is controlled to extend and push the slide rod 25 to slide on the inner wall of the groove rod 23, so that the pressure plate 28 drops, causing one end of the pressure plate 28 to... As the pressure plate 28 continues to descend after contacting the top of the item box, it rotates on the outer surface of the rotating shaft 26, causing the coil spring 27 to deform. This causes the bottom of the pressure plate 28 to adhere to the top of the item box. Then, the operation of the second servo motor 21 and the first electric push rod 24 stops, leaving the pressure plate 28 pressed against the top of the item box. The second electric push rod 29 then extends, controlling one end of the pressure rod 210 to press against the top of the pressure plate 28, further restricting the position of the item box on the fork 7. Subsequently, the vehicle body... The item box is moved to the unloading area according to the predetermined route. When the frame 1 moves or when the fork 7 is loading or unloading the item box, if one end collides with an object, the rubber rod 35 can block it to reduce the damage caused by the collision. The first servo motor 4 controls the lead screw 5 to rotate, so that the frame rod 6 moves downward on the outer surface of the lead screw 5 and the outer surface of the frame 1, so that the position of the fork 7 is offset from the position of the shelf where the item box is placed. After the fork 7 descends to the bottom of the shelf, the bottom of the item box contacts the shelf and enters the surface of the shelf to complete the unloading.
