Abstract

La présente invention concerne une plate-forme de travail de maintenance d'un générateur d'énergie éolienne, comprenant: une plaque de travail de tour disposée de façon à être espacée de la circonférence extérieure de la tour du générateur d'énergie éolienne de manière à s'élever le long de la direction longitudinale de la tour, et sur laquelle est monté un utilisateur; un rouleau disposé entre la plaque de travail et la tour; et une pièce fonctionnelle comprenant un support variable qui soutient le rouleau de sorte que celui-ci vient en contact étroit avec la circonférence externe de la tour, et présente une longueur variable. Selon la présente invention, la plate-forme de travail de maintenance d'un générateur d'énergie éolienne peut être montée à bord par l'utilisateur, lorsqu'elle est prévue pour la tour, et peut être soulevée, ce qui permet d'améliorer la stabilité et l'efficacité de travail de l'utilisateur en réduisant l'influence du vent ou de son environnement. De plus, la position d'un dispositif de maintenance peut être ajustée en fonction de la position d'une pale dans laquelle la pale est arrêtée, de façon à pouvoir effectuer la maintenance de la pale et de la tour, permettant ainsi d'améliorer l'efficacité de travail.
