LIFTING UNIT, PLATFORM EQUIPPED THEREWITH AND WAREHOUSE ROBOT Russian patent published in 2025 - IPC B65G1/04 

FIELD: lifting devices.

SUBSTANCE: lifting assembly comprises a lifting frame having a longitudinal central plane, a gear wheel capable of cooperating with a guide and capable of being rotated about the axis of the gear wheel, as well as first, second and third rollers, capable of rotating around the axes of the first, second and third rollers, respectively. Gear wheel axis perpendicular to longitudinal central plane is parallel to axes of the first and second rollers. Distance along vertical line between axis of gear wheel and axis of the second roller is less than radius of gear wheel. Axis of the third roller is parallel to longitudinal central plane.

EFFECT: when the lifting assembly interacts with the guide, the first and second rollers are capable of covering the first segment of the guide on both sides, limiting the longitudinal movement of the lifting frame, and the third roller is capable of resting against the second guide segment, limiting the transverse movement of the lifting frame.
