Fecha de publicación: 09/02/2024 Fuente: WIPO "circular economy" The utility model relates to the technical field of AGV transfer robots, and discloses an AGV transfer robot with a spiral lifting mechanism, which comprises a host, a housing and a support table, the housing is clamped with the host, a support plate is mounted on the side wall of an inner cavity of the housing, and a plurality of groups of support columns are distributed on the bottom wall of the inner cavity of the host. And rotary lifting mechanisms are distributed on the supporting plate and the supporting column, are used for driving and controlling the supporting table to ascend and descend and comprise driving boxes, connecting blocks, double-head motors, connecting shafts, helical tooth driving wheels, helical tooth driven wheels, threaded lead screws and shaft sleeves. When the spiral lifting mechanism works, the helical tooth driving wheel is driven to rotate and the helical tooth driven wheel meshed with the helical tooth driving wheel is driven to rotate through the connecting shaft by utilizing the positive and negative rotation of the double-head motor, so that the threaded screw rod is driven to spirally ascend or descend along the vertical direction, and the lifting or descending function of the support table is realized by matching with the shaft sleeve; the AGV carrying robot is convenient to adapt to goods or workbenches of different heights, the load unloading task is completed, and the applicability of the AGV carrying robot is improved.
