Description

Technical Field

[0001] The utility model relates to the technical field of logistics automation, and in particular designs a lifting and reversing device for a four-way shuttle vehicle for a pallet. Background Art

[0002] A shuttle refers to a motorized device used in warehousing and logistics to quickly move goods around a warehouse. These vehicles are typically able to shuttle between shelves to efficiently store and retrieve merchandise. Four-way shuttles are key equipment in modern warehousing and logistics, improving warehouse operational efficiency and cargo storage capacity. Their multi-directional and vertical movement capabilities make them ideal for handling all types of goods. However, existing four-way shuttles are typically equipped with two separate systems for reversing and lifting, resulting in a complex frame structure and cumbersome reversing and lifting operations. Utility Model Content

The lifting drive mechanism is connected to a rotating shaft, and a group of gear sets are connected to each end of the rotating shaft. Racks meshing with the gear sets are provided on both sides of the gear set, and the racks are connected to the wheel mounting plate. A lifting plate is provided above the mother track wheel, and a limit block is provided at the bottom of the lifting plate. The wheel mounting plate lifts the lifting limit block to make the lifting plate rise; when the lifting drive mechanism drives the rotating shaft to rotate, the rotating shaft drives the gear set to rotate, and the gear set drives the rack and the mother track wheel to move up and down to switch the relative height between the sub-track wheel and the mother track wheel or lift the lifting limit block.

[0005] Furthermore, a guide column is provided at the bottom of the jacking plate, a guide groove matching the guide column is provided on the mother wheel, and a limit block is provided at one end of the guide column close to the jacking plate.

[0006] Furthermore, the lifting drive mechanism includes a motor and a reducer connected to the motor, and the rotating shaft is connected to the reducer.

The reducer 2 is connected to the motor 1, the rotating shaft 3 is connected to the reducer 2, and the axis of the rotating shaft 3 is parallel to the axis of the output shaft of the lifting drive mechanism. The gear set includes four mutually meshing gears (5, 6, 7, 8), and the two ends of the rotating shaft 3 are connected to the gear 5 located at one end through the coupling 4. The rack 9 is arranged on both sides of the gear set and meshes with the gears located at both ends respectively. The rack 9 is connected to the mother track wheel 10 through the wheel mounting plate 14, and the frame is provided with a guide rail 15 extending up and down, and the wheel mounting plate 14 passes through the guide rail 15 horizontally, and the wheel mounting plate 14 cooperates with the guide rail 15 in the up and down direction and can move along the guide rail 15. The frame is also provided with a guide groove 18, and the main shaft of the mother wheel 10 is installed in the guide groove 18. When the mother wheel rack 9 moves up and down, the mother wheel 10 moves along the guide groove 18, and the wheel mounting plate 14 moves in the guide rail 15 to limit the moving direction and improve the stability during movement. A lifting plate 11 is provided above the mother wheel 10, and a notch matching the lifting plate is provided on the frame 12. A guide column 16 is provided at the bottom of the lifting plate 11, and a limit block 17 is provided at one end of the guide column 16 close to the lifting plate 11, and a guide groove matching the guide column 16 is provided on the mother wheel 10. When the mother wheel 10 descends, the guide column 16 slides out of the guide groove, and the lifting plate 11 is located in the notch of the frame, flush with the upper end surface of the frame, and does not descend with the mother wheel 10. At this time, the mother wheel can descend to a height lower than the sub-wheel 13 to complete the reversal. When the mother wheel 10 rises, the limit block 17 is lifted up and drives the lifting plate 11 to rise.
