Abstract

La présente invention concerne un dispositif de support rotatif, un mécanisme de remplacement de plateau, un système de remplacement rapide et un procédé de levage, le dispositif de support rotatif comprenant un châssis, un disque rotatif et un mécanisme d'entraînement, le disque rotatif étant emmanché sur le châssis, et la partie supérieure du disque rotatif étant utilisée pour raccorder de manière fixe un support à mettre en rotation ; et le mécanisme d'entraînement est raccordé au disque rotatif et est utilisé pour entraîner le disque rotatif en rotation sur la circonférence extérieure du châssis. Un ensemble plateau de batterie comprend un mécanisme de support et au moins un ensemble rotatif situé sur le mécanisme de support ; l'ensemble rotatif comprend un plateau de batterie et le dispositif de support rotatif décrit ; le fond du châssis est raccordé au mécanisme de support, et la partie supérieure du disque rotatif est raccordée au plateau de batterie. Un système de remplacement rapide pour un boîtier de batterie comprend l'ensemble plateau de batterie décrit. Selon la présente invention, étant donné que le plateau de batterie est de petite taille et de poids léger, le plateau de batterie est directement mis en rotation au moyen du disque rotatif, ce qui permet d'améliorer considérablement la précision de rotation du dispositif de support rotatif, et d'éviter efficacement une position imprécise lorsque le boîtier de batterie est pris et placé. Par ailleurs, le dispositif de support rotatif présente une structure simple, occupe un espace réduit, et est facile à entretenir.
