LIFTING MECHANISM AND LIFTING APPARATUS USING LIFTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/222990
Kind Code:
A1
Abstract:
Disclosed is a lifting mechanism. The lifting mechanism is installed on a lifting apparatus. The lifting apparatus comprises a bearing unit, and the lifting mechanism is arranged at the bottom of the bearing unit. The lifting mechanism comprises a driving assembly and a lifting assembly. The driving assembly comprises a wheel shaft fixing block, driving wheels and a power source. The lifting assembly comprises a lead screw nut and a lead screw, and the upper end of the lead screw is fixedly connected to the bearing unit. When the lifting mechanism moves forward, all the driving wheels come into contact with a foundation surface and move the lifting apparatus on the foundation surface; and when the lifting mechanism is used for lifting, all the driving wheels rotate on the foundation surface to drive the lead screw nut to rotate about a vertical axis relative to the bearing unit so as to drive the lead screw to move in the vertical direction to lift the bearing unit. The present invention has at least the following advantages: multi-angle rotation of all the driving wheels can be realized, and the forward movement of a conveying robot and the lifting of the lifting mechanism are realized under the action of the same driving assembly.
