ROPELESS ELEVATOR WIRELESS POWER TRANSMISSION SYSTEM

WIPO Patent Application WO/2020/013523

A1

The present invention relates to a ropeless elevator wireless power transmission system. More specifically, the present invention provides a ropeless elevator wireless power transmission system for horizontally transferring an elevator car by using a carrier. Power transmission lines are installed along a vertical shaft and a horizontal shaft, respectively, and pickup devices are installed in the elevator car and the carrier, respectively, such that when the elevator car moves vertically and horizontally, power is selectively delivered through the car pickup device and the carrier pickup device, thereby always enabling stable wireless power transmission. A separate auxiliary vertical power transmission line is installed in the carrier to be able to receive a wireless power signal from the horizontal power transmission line such that, when the elevator car moves vertically, wireless power can be supplied in a double pickup type in the process of passing through a branching section. Accordingly, stable wireless power supply is always possible, and the system configuration can be simplified, thereby making installation and control operations easy and further facilitating maintenance/management.
