[0002] AGV forklifts include pallet forklift AGV, wide-leg stacker AGV, and footless stacker AGV. They are used for the logistics turnover of stacked pallet goods and consist of a hydraulic lifting system, differential drive system, PLC control system, guidance system, communication system, warning system, operating system, and power supply. They are programmable wireless dispatchable automatic guided vehicles that integrate hydraulic lifting and PLC control. They use electromagnetic induction as a navigation method to assist RFID identification and can run on complex paths and multi-site reliable tracking. The main drive adopts a self-developed differential servo motor drive and is equipped with a high-precision angle steering servo, which makes the whole vehicle respond quickly and accurately. The independent hydraulic lifting system assists the high-precision displacement sensor so that the forklift can stop at any position within its lifting range, greatly improving the flexibility of loading and the position accuracy of lifting.

[0003] A Chinese patent with publication number "CN213387649U" discloses an intelligent AGV forklift body, which specifically relates to the field of AGV forklift technology, including a forklift body, a forklift arm is movably mounted on one side of the forklift body, a storage plate is arranged inside the forklift arm, a forklift head is fixedly connected to the side of the forklift arm away from the forklift body, side panels are arranged on the front and rear sides of the forklift arm, a top plate is arranged on the top of the forklift arm, and the top plate is fixedly connected to one side of the forklift body.

[0004] However, this forklift still has some shortcomings, because the way the forklift forks items is to place the items on the forklift arm through the forklift head, and then lift the forklift arm to transfer the items. However, the top of the forklift arm does not have a structure to limit the items. During the transfer, the shaking caused by the forklift will cause the items to fall from the forklift arm, which will not only damage the items, but also affect the subsequent work efficiency of the forklift. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide an intelligent AGV forklift to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] An intelligent AGV forklift comprises a forklift body, a bracket is fixedly connected to the front side of the forklift body, a forklift arm is installed at the front lower end of the bracket, a forklift head is threadedly connected to the front side of the forklift arm, a support plate is fixedly connected to the front upper end of the bracket, a telescopic cylinder is fixedly connected to the top end of the support plate, the bottom end of the telescopic cylinder penetrates the support plate, a clamping plate is fixedly connected to the bottom end of the telescopic cylinder, the position of the clamping plate is symmetrical to the position of the forklift arm, a first telescopic rod is fixedly connected to the bottom end of the support plate, and the bottom end of the first telescopic rod is fixedly connected to the top end of the clamping plate. Due to the existence of the clamping plate, when an object is forked onto the forklift arm, the user can start the telescopic cylinder to push the clamping plate downward, and the clamping plate can clamp and fix the top end of the object, thereby preventing the object from falling during transportation.

[0008] As a preferred technical solution, a groove is provided at the bottom end of the splint, and a rubber pad is fixedly connected to the inner side of the groove. The rubber pad covers the inner side of the groove, and the position of the bottom end of the rubber pad is on the same horizontal line as the bottom end of the splint. Since the rubber pad has good anti-slip and shock-absorbing effects, the objects can be clamped more stably, and collisions between the objects and the splint can also be avoided.

[0009] As a preferred technical solution, a slot is provided on the front side of the forklift arm, and a plug plate matching the slot is fixedly connected to the rear side of the forklift head, the plug plate is plugged into the inner side of the slot, and a first screw hole is provided on the top of the forklift arm, the first screw hole passes through the forklift arm and the plug plate, a first bolt is threadedly connected to the inner side of the first screw hole, and the bottom end of the first bolt is threadedly connected to the inside of the plug plate through the first screw hole. Because the forklift head is threadedly fixed to the front side of the forklift arm, when the forklift head needs to be disassembled and maintained later, the user only needs to unscrew the first bolt out of the first screw hole to pull out the forklift head, thereby achieving the purpose of convenient disassembly and assembly of the forklift head.

[0010] As a preferred technical solution, a limiting plate is fixedly connected to the outer wall of the support plate, a first sliding groove is provided on the inner side of the limiting plate, a connecting block is slidably connected to the inner side of the first sliding groove, one side of the connecting block is fixedly connected to the other side of the forklift arm, due to the existence of the limiting plate, the position of the forklift arm sliding up and down can be effectively limited, so that the forklift arm can be more stable when adjusting the height.

[0011] As a preferred technical solution, a baffle is slidably connected to the inner wall of the limit plate, a second telescopic rod is fixedly connected to the front side of the baffle, a push plate is fixedly connected to the front side of the second telescopic rod, the bottom end of the push plate is fixedly connected to the fixed plate, the bottom end of the fixed plate is in contact with the top of the forklift arm, and due to the presence of the second telescopic rod, it is convenient to adjust the position of the push plate. When the position of the push plate changes, the position of the object placed on the top of the forklift arm will also change accordingly. Adjusting the position of the push plate according to the size of the object can avoid leaving a lot of space when the object is forked onto the forklift arm, thereby facilitating the subsequent unloading of the object.

[0012] As a preferred technical solution, a second sliding groove matching the baffle is provided on the inner wall of the limit plate, and the baffle is slidably connected to the inner wall of the limit plate through the second sliding groove. The opening of the second sliding groove facilitates the up and down sliding of the baffle, thereby preventing the baffle from being pinched off when adjusting the height of the forklift arm.

[0013] As a preferred technical solution, a fixing block is fixedly connected to the rear side of the fixing plate, and the bottom end of the fixing block is in contact with the top end of the forklift arm. A second screw hole is provided at the top end of the fixing block, and a second bolt is threadedly connected to the inner side of the second screw hole. The bottom end of the second bolt is in contact with the top end of the forklift arm through the second screw hole. When the position of the push plate is adjusted, the user can tighten the second bolt, thereby limiting and fixing the position of the push plate, thereby preventing the push plate from being displaced.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] First, when using the forklift body, the forklift head can be used to place the item on the forklift arm. After the item is placed, the user can adjust the height of the forklift arm, and then adjust the height of the clamping plate through the telescopic cylinder. The clamping plate can clamp and fix the top of the item, thereby effectively limiting and fixing the position of the item, thereby preventing the item from falling during transportation. The first telescopic rod can improve the stability of the clamping plate without hindering the adjustment of the clamping plate height, so as to avoid the clamping plate from angular deviation.

[0016] Second, because the sizes of different items are different, the user can adjust the position of the push plate through the second telescopic rod, and then fix the position of the push plate by screwing the second bolt to fix the fixing block. The position of the push plate changes as the space for placing items on the top of the forklift arm changes accordingly. By adjusting the space for placing items on the forklift arm to a size that matches the items, it can be avoided that a large amount of space is left when the items are forked on the forklift arm. At the same time, forking and transporting items without leaving any space is also more conducive to unloading the items later, thereby improving the work efficiency of item disassembly.
