Wireless power supply system for elevators

Abstract

The present invention relates to the technical field of wireless energy transmission, and specifically discloses a wireless power-taking elevator power supply system, which includes a transmitting end arranged in the elevator shaft and a pick-up end arranged on the elevator car; the transmitting end includes a launching guide rail, and the launching guide rail At least one energy transmission section in the elevator car is arranged along the moving direction of the elevator car; the pick-up end includes a power taker, and the power taker includes a receiving coil adapted to the magnetic field distribution of the transmitting guide rail; The moving receiving coil of the energy transmission section of the guide rail and the transmitting guide rail always maintain wireless magnetic coupling. The present invention arranges the launch guide rail in the elevator shaft, and arranges the corresponding electric pick-up on the elevator car, and the launch guide rail is set according to the working path of the elevator car, so that in the working process of the elevator car, the pick-up and launch guide rail Always maintain wireless magnetic coupling to obtain energy for uninterrupted and continuous power supply to the elevator car.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a wireless power-taking elevator power supply system. Background technique [0002] As a kind of electromechanical equipment that moves vertically, elevators currently supply power to the elevator car by dragging the accompanying cables. The accompanying cables move up and down with the elevator car, which has the disadvantages of low efficiency and high maintenance costs. Especially in super high-rise buildings and high-speed elevators, the running speed of the elevator is too high or the free suspension length is too long, which will increase the bearing load of the traveling cable, and there are safety risks such as wear, accelerated aging, and unsafe exposure, which greatly reduces the reliability of the elevator. performance and operational efficiency. SUMMARY OF THE INVENTION [0003] The present invention provides a wireless power-taking elevator po...

[0002] As a kind of electromechanical equipment that moves vertically, the elevator currently uses the method of dragging the accompanying cable to supply power to the elevator car. The accompanying cable goes up and down with the elevator car, which has the disadvantages of low efficiency and high maintenance costs.

Especially in super high-rise buildings and high-speed elevators, if the elevator running speed is too high or the free suspension length is too long, it will increase the carrying load of the accompanying cables, and there will be safety risks such as wear, accelerated aging, and unsafe exposure, which will greatly reduce the reliability of the elevator. performance and operational efficiency
