The invention belongs to a lifting device used for a wall climbing robot, and relates to a suction cup lifting device with an air channel on-off function. The suction cup lifting device comprises rails, chain wheels and a chain, wherein suction cups are in threaded connection with suction cup fixing plates by suction cup air exhaust joints; guide posts are fixedly connected with guide post fixing plates; track rolling wheels are connected with the guide post fixing plates; mechanical valves are in threaded connection with the guide post fixing plates and the suction cup fixing plates respectively; bearing supports are in threaded connection with the guide post fixing plates and the suction cup fixing plates respectively; linear bearings are in interference connection with bearing supports; optical axes are slidingly connected with the linear bearings; one end of each optical axis is in threaded connection with a guide sleeve; first springs are connected with the exteriors of the optical axes in a sleeving manner; the other ends of the optical axes are in threaded connection with lifting height adjusting nuts; the guide sleeves are slidingly connected with the guide posts; and suction cup module connecting plates are fixedly connected with the guide sleeves. The suction cup lifting device has the advantages that the structure is novel; no rolling creases are generated when the suction cups make contact with an adsorption surface; pressure fluctuation of a vacuum system is small; the volume and weight of the robot are reduced; and the cost is lowered.
Description
technical field [0001] The invention belongs to a lifting device for a wall-climbing robot, in particular to a suction cup lifting device with an air circuit on-off function. Background technique [0002] Suction cups are widely used in wall-climbing robots that require negative pressure adsorption. Generally, there are two types of multi-suction cup wall-climbing robots: legged and crawler. Considering the crawler wall-climbing robot, in the process of continuous movement, before the suction cup is in contact with the crawling surface, the phenomenon of suction cup curling will inevitably occur. At the same time, when the suction cup is adsorbed and detached from the adsorption surface, the pressure of the vacuum system is likely to fluctuate, which leads to the failure of the suction cup and seriously affects the reliability of the robot. Contents of the invention [0003] The invention provides a suction cup lifting device with the function of on-off air path, so as to...
