Magnetic levitation rail type material vertical conveying system and method

Abstract

This invention discloses a magnetic levitation guide rail vertical material conveying system and method, including a permanent magnet guide rail system, a levitation and guiding mechanism, a linear motor drive mechanism, and a control system. The permanent magnet guide rail system is vertically arranged along the building shaft to provide a stable magnetic field to generate levitation and guiding forces. The levitation and guiding mechanism is disposed on the conveying car and generates levitation force under the action of the magnetic field of the permanent magnet guide rail system, so that the car is suspended above the guide rail with a preset gap and achieves stable guidance. The linear motor drive mechanism includes a stator coil disposed on the side of the guide rail and a mover permanent magnet disposed on the car, which drives the car to move up and down along the guide rail direction through electromagnetic action. The control system receives multi-source sensor signals and performs closed-loop control to realize car positioning, speed adjustment, levitation gap control, and safety protection. This invention can achieve low noise and high positioning accuracy, while also possessing high robustness and self-diagnostic capabilities.
