Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic mechanical field, especially a kind of stereoscopic warehousing robot. BACKGROUND

[0002] The axle of the wheel of the conventional stereoscopic warehousing robot is connected to the main body of the stereoscopic warehousing robot by rigid connection. The stereoscopic warehousing robot carries goods to walk on the track. Because of rigid connection, the extrusion force generated by the gravity of goods and the gravity of the stereoscopic warehousing robot is directly transmitted to the wheel of the stereoscopic warehousing robot, which causes the wheel of the stereoscopic warehousing robot to be severely worn during walking.

[0003] In the shelf area, there is a height difference between the tracks arranged in different directions (for example, the parent track and the child track). When the stereoscopic warehousing robot switches from a track with a higher longitudinal position to a track with a lower longitudinal position, especially under heavy load, the wheel will be damaged due to the great impact force when it touches the track at the low position. Because the wheel and the main body of the stereoscopic warehousing robot are connected by rigid connection, the wheel will bounce vertically when it touches the track at the low position, and the bounce will be transmitted to the main body of the stereoscopic warehousing robot and the objects placed on it. The objects will move under the action of the bounce. SUMMARY
