DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0018] Reference Figure 1-3, an intelligent forklift for unmanned handling, comprising a forklift body 1, a lifting frame 2 is fixedly connected to one side of the forklift body 1, a driving motor 3 is fixedly connected to the top of the lifting frame 2, a lifting screw 4 is fixedly connected to the output end of the driving motor 3, and a connecting platform 5 is threadedly connected to the outer side of the lifting screw 4, and the connecting platform 5 is arranged on the inner side of the lifting frame 2, and one side of the connecting platform 5 is fixedly connected to two symmetrically arranged fork plates 6, through the operation of the driving motor 3, the lifting screw 4 is driven to rotate, and then the connecting platform 5 is moved up and down along the lifting screw 4 under the limit of the lifting frame 2 to adjust the height of the goods or adjust the height of the fork plate 6 according to the height of the goods, and a telescopic plate 7 is arranged inside one end of the two fork plates 6, and a through groove 10 is opened at one end of the telescopic plate 7, and a steering gear 11 is fixedly connected to the inside of one end of the through groove 10, and a rotating shaft 12 is fixedly connected to the output end of the steering gear 11, and one end of the rotating shaft 12 is rotatably connected to the inner wall of the through groove 10, and a blocking plate 13 is fixedly connected to the outer side of the rotating shaft 12.

[0019] An electric push rod 15 is fixedly connected to the bottom of one side of the fork plate 6, and the output end of the electric push rod 15 is connected to one end of the telescopic plate 7. A card slot 14 is provided on the top surface of one end of the blocking plate 13. The electric push rod 15 is used to push the telescopic plate 7 to extend and retract, so that the blocking plate 13 contacts the bottom of the cargo. The card slot 14 is used to clamp the blocking plate 13 on the edge of the telescopic plate 7, so that the blocking plate 13 is rotated and clamped to form a tilted state to block the cargo.

[0020] When the fork plate 6 forks the goods, the electric push rod 15 pushes the telescopic plate 7 to extend out of the fork plate 6, and then the servo 11 drives the rotating shaft 12 to rotate, and then drives the blocking plate 13 to rotate. The blocking plate 13 rotates to make the slot 14 stuck in the edge of the telescopic plate 7, and then the output end of the electric push rod 15 retracts, driving the telescopic plate 7 to retract, so that the blocking plate 13 contacts the bottom of the goods. At this time, the blocking plate 13 is in an inclined state, blocking the goods to prevent them from falling during transportation.

[0021] Connecting arms 8 are fixedly connected to both sides of the middle of the connecting platform 5, a connecting tube 16 is fixedly connected to the inner side of one end of the connecting arm 8, a connecting rod 17 is movably connected inside the connecting tube 16, and one end of the connecting rod 17 is fixedly connected to the side guard plate 9.

[0022] A through hole is opened at one end of the connecting arm 8, and one end of the connecting rod 17 passes through the through hole. A spring 18 is arranged on the outer side of the end of the connecting rod 17 close to the side guard plate 9, and the end of the connecting rod 17 away from the side guard plate 9 is fixedly connected to a limiting plate 19. Through the setting of the limiting plate 19, one end of the connecting rod 17 will not pass through the through hole and detach from the connecting tube 16, thereby playing a limiting role.

[0023] When the fork plate 6 lifts the goods, it will push the side guard plate 9, and the side guard plate 9 will squeeze the spring 18 and make the connecting rod 17 sink into the connecting tube 16. Under the reaction of the spring 18, the side guard plate 9 will be close to the outside of the goods, ensuring the stability of the goods during the transfer process and preventing the goods from tilting during transportation.

[0024] One end of the spring 18 is fixedly connected to one end of the connecting tube 16, and the other end of the spring 18 is fixedly connected to the middle of one side of the side guard plate 9. The opposite side of the side guard plate 9 is fixedly connected with a rubber pad, and the rubber pad can prevent the side guard plate 9 from damaging the outer surface of the cargo during contact with the cargo.
