[0021] See also Figure 1-4 , the utility model provides a technical solution for a pallet lifting device:
[0022] Embodiment 1:
[0023] like Figure 1-3 As shown, a pallet lifting device comprises a lifting frame 1, a screw rod 2 is arranged on one side of the lifting frame 1, an auxiliary rod 3 is arranged on the other side of the lifting frame 1, a pallet 5 is sleeved on one end of the screw rod 2 and the auxiliary rod 3, a servo motor 4 is arranged on the top of the lifting frame 1, two supporting columns 6 are arranged inside the pallet 5, one end of the two supporting columns 6 are sleeved on a moving block 7, one side of the two moving blocks 7 are arranged with a rack 10, the bottom of the two racks 10 are arranged with a moving plate 11, a push bar 16 is arranged on one side of the top of the pallet 5, a micro motor 8 is arranged in the middle of the bottom end of the pallet 5, the output shaft of the servo motor 4 is transmission-connected with one end of the screw rod 2, and the two moving plates 11 are used in conjunction with the pallet 5 to increase the storage space for goods. Therefore, the positions of the two moving plates 11 can be adjusted according to the quantity of goods, thereby improving the practicability of the lifting device.
[0024] Embodiment 2:
[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, the two moving blocks 7 are movably mounted on one end of the two supporting columns 6 respectively, a U-shaped plate 13 is fixedly installed on the top of the pallet 5, and a restraining plate 15 is arranged on one side of the push bar 16. The utility model provides a pallet lifting device, by setting the supporting columns 6, the U-shaped plate 13, the abutment rod 14 and the restraining plate 15. After the servo motor 4 is started, the screw rod 2 rotates accordingly, and the pallet 5 mounted therewith can move up and down, so that the goods can be lifted from the ground to the production line, and the push bar 16 is pushed to one side to transmit the force to the restraining plate 15.
[0026] Working principle: Pallet lifting device, also known as pallet lifter and pallet lifter, is a mechanical equipment used for vertically lifting pallets. It is usually used in warehouses, logistics centers and factory production lines to lift goods on pallets from the ground to shelves and production lines, or lower them from shelves or production lines to the ground. Pallet lifting device has a wide range of applications, including storage and retrieval of warehouse goods, material transmission on production lines, and vehicle lifting in auto repair shops. By using pallet lifting device, work efficiency can be improved and the labor intensity of manual handling can be reduced. However, in order to reduce the footprint of pallet 5, the space of pallet 5 is small, and the space that can be used to store goods has certain limitations. When the number of goods is large, the number of times pallet 5 is used can be increased to complete the transportation of goods. Traditional lifting device cannot adjust the space where goods can be placed according to the number of goods, which reduces the practicality of the lifting device. Therefore, when the number of goods is relatively large, the staff can start the micro motor 8. After starting the micro motor 8, it drives the circular gear 9 to rotate synchronously. When the circular gear 9 rotates clockwise, it drives The two gear racks 10 meshing with the two gear racks 10 move toward each other, and then the two moving plates 11 move toward each other. The two moving plates 11 gradually extend outward from the bottom of the tray 5. The two moving plates 11 and the tray 5 are used in conjunction with each other to increase the storage space for goods. Therefore, the positions of the two moving plates 11 can be adjusted according to the number of goods, thereby improving the practicality of the lifting device. When the number of goods is small, the circular gear 9 rotates counterclockwise, driving the two gear racks 10 meshing with the two gear racks 10 to move relative to each other, and the moving block 7 can be at one end of the support column 6. When the servo motor 4 moves, the two movable plates 11 can move relative to each other, so that the two movable plates 11 can be stored at the bottom of the tray 5. At this time, the movable plates 11 will not occupy a large area and are convenient for storage. After starting the servo motor 4, the screw rod 2 rotates accordingly, and the tray 5 mounted thereon can move up and down, so that the goods can be lifted from the ground to the production line. By pushing the push bar 16 to one side, the force can be transmitted to the restraining plate 15, and the restraining plate 15 can move at one end of the abutting rod 14. The push bar 16 applies pressure to the goods, thereby speeding up the unloading of the goods.
