Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A dual-system lifting device comprises an upright post 1 and a pair of lifting assemblies 5, wherein the lifting assemblies 5 are symmetrically arranged on two opposite sides of the upright post 1 in the horizontal direction, and driving devices are respectively arranged between the lifting assemblies 5 and the upright post 1, so that the two lifting assemblies 5 can be lifted independently;

when the lifting device is applied to the existing surfacing system, when one lifting assembly 5 or the robot breaks down, the other lifting assembly 5 can be independently controlled to be matched with the robot to complete surfacing work, and when the damaged lifting assembly 5 is positioned in a high space, maintenance personnel can be conveyed to the high space through the other lifting assembly 5 to maintain the broken lifting assembly 5, so that the fault tolerance of the surfacing system is greatly improved.

The upright column 1 is a quadrangular prism, wherein a pair of opposite outer side surfaces of the upright column 1 are provided with racks 2, the racks 2 extend and are fixedly installed along the vertical direction, a gear 101 meshed with the racks 2 is installed on the lifting assembly 5, the gear 101 and the racks 2 form a main structure of the driving device, and the lifting assembly 5 is moved and fixed by driving the gear 101 to rotate or fix.
