Technical Field
[0001] This utility model relates to the field of forklift technology, and in particular to an AGV forklift mast device. Background Technology
[0002] Automated Guided Vehicles (AGVs), as an important component of automated logistics equipment, are widely used in industrial production, warehousing and logistics, and other fields for the picking and handling of goods.
[0003] Traditional AGV forklift mast devices have some limitations. On the one hand, when dealing with tall goods, such as large boxes and cabinets, traditional mast devices cannot effectively prevent the goods from becoming unstable and swaying due to their high center of gravity during the picking and handling process. This results in a greater risk of the goods falling, which seriously affects the safety and reliability of handling. Utility Model Content
[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide an AGV forklift mast device, thereby enhancing handling safety and reliability.

A first fixing plate and a second fixing plate are respectively arranged above and below the left and right ends of the inner side of the mast. Several fixing shafts are fixed on opposite sides of the two first fixing plates and the two second fixing plates. Rollers located between the mast and the guide rails are movably connected to the outer surface of the fixing shafts. A first connecting seat is fixed at the bottom of the two first fixing plates, and a second connecting seat is fixed at the top of the two second fixing plates. A second servo cylinder is fixed between the first connecting seat and the second connecting seat.
[0006] Preferably, an integral clamp is fixed to the side of the two first fixing plates away from the gantry.
[0007] Preferably, a fork carriage is fixed to one side of the two second fixing plates away from the gantry, and a pair of forks are fixed to one side of the fork carriage.
[0008] Preferably, a first servo cylinder is fixed at the center of the gantry, a sprocket seat is fixed at the telescopic end of the first servo cylinder, a chain is sleeved on the outer surface of the sprocket seat, a connecting plate is fixed on the surface of the gantry, one end of the chain is fixed to the fork, and the other end of the chain is fixed to the connecting plate.
[0009] Preferably, the roller is made of wear-resistant material and is adapted to the guide rail so that it can roll smoothly along the guide rail.
[0010] Preferably, the integral clamp is an adjustable structure that can be adjusted according to the size and shape of the goods.
[0011] The beneficial effects of this utility model are:
[0012] 1. The height of the integrated clamp can be adjusted by the second servo cylinder, making the product applicable to some tall goods, such as boxes and cabinets, forklifts, clamping and straightening the goods to prevent instability and swaying caused by the high center of gravity of the goods, thereby enhancing the safety and reliability of handling.
[0013] 2. Simultaneously, the forks and integrated clamps can be used to clamp goods on two layers of the rack at the same time, and the distance between the goods can be adjusted by the second servo cylinder, thereby speeding up the handling efficiency. Attached Figure Description

[0019] Reference Figure 1-4The AGV forklift mast 1 device includes a mast 1. Guide rails 16 are threaded to both the left and right ends of the inner side of the mast 1. A first fixing plate 9 and a second fixing plate 10 are respectively arranged above and below the left and right ends of the inner side of the mast 1. Several fixing shafts 11 are welded to the opposite side of the two first fixing plates 9 and the two second fixing plates 10. Rollers 12 located between the mast 1 and the guide rails 16 are movably connected to the outer surface of the fixing shafts 11. A first connecting seat 13 is fixed to the bottom of the two first fixing plates 9. A second connecting seat 14 is fixed to the top of the two second fixing plates 10. A second servo cylinder 15 is fixed between the first connecting seat 13 and the second connecting seat 14. By activating the second servo cylinder 15, the first connecting seat 13 and the first fixing plate 9 are moved up and down. The movement of the first fixing plate 9 causes the integral clamp 7 to move up and down. At the same time, the mast 1 and the guide rails 16 guide the rollers 12 to move more smoothly.
[0020] Two first fixing plates 9 are fixed with an integrated clamp 7 on the side away from 1. The integrated clamp 7 is an adjustable structure that can be adjusted according to the size and shape of the goods. The working principle of the integrated clamp 7 is to clamp or release the goods by driving the clamping arm with a hydraulic cylinder, thereby achieving the clamping of the goods. This design makes the forklift more flexible and efficient in handling goods of different shapes and sizes. The forks 6 and the integrated clamp 7 work together to simultaneously pick up and clamp goods on both the upper and lower layers.
[0021] Two second fixing plates 10 are fixed with fork carriages 5 on the side away from the mast 1, and a pair of forks 6 are fixed on one side of the fork carriages 5. The design of the forks 6 enables them to stably carry and move various goods, and they are widely used in logistics links such as warehousing, transportation and packaging.
[0022] A first servo cylinder 2 is fixed at the center of the gantry 1. A sprocket seat 3 is fixed at the telescopic end of the first servo cylinder 2. A chain 4 is fitted on the outer surface of the sprocket seat 3. A connecting plate 8 is fixed on the surface of the gantry 1. One end of the chain 4 is fixed to the fork 5, and the other end of the chain 4 is fixed to the connecting plate 8. The first servo cylinder 2 drives the sprocket seat 3 to rise and fall, and drives the fork 5 to move synchronously through the closed-loop transmission of the chain 4.
[0023] The roller 12 is made of wear-resistant material and is adapted to the guide rail 16, so that it can roll smoothly along the guide rail 16.
[0024] In use, the extension and retraction of the first servo cylinder 22 drives the sprocket seat 33 to move, which in turn causes the chain 4 to drive the fork carriage 5 and the forks 6 to move up, down, and horizontally to meet the needs of picking up goods at different heights and positions. After the forks 6 pick up the goods, the integrated clamp 7 can clamp and fix the goods to prevent them from swaying and falling during handling due to instability of the center of gravity, effectively improving the safety and reliability of handling. The second servo cylinder 15 can also be activated to move the integrated clamp 7 up and down according to the different heights of the goods, thereby clamping and fixing the goods at different heights. It can also simultaneously clamp two layers of goods on the shelf. The distance between the goods can also be adjusted. The rollers 12 roll within the guide rails 16, reducing the friction between the mast 1 and the guide rails 16, making the movement of the forks 6 and carriage 5 smoother and improving work efficiency.
