Description

风电机组叶片自更换装置及其工作方法 技术领域
本发明关于一种风电机组领域， 更具体地说， 关于一种风电机组叶片自 更换装置。 背景技术
目前， 风电机组的叶片更换一般采用各种臂架类型起重机将叶轮装置卸 下， 然后在地面上进行叶片的更换， 之后再将叶轮吊装到风电机组上。 其具 有如下缺点：
1、 更换时需要借助外部工具（如起重机等）， 给更换过程带来较多不便， 并且要求起重机的臂长较长， 起重量较大， 如兆瓦级风机叶轮中心高一般在 60m以上， 重量 30000kg以上。 另外， 风电机组一般设置在偏远地区， 给起 重机的运输带来了困难， 对于海上型风电机组尤其困难。
2、 更换工作量大。 更换叶片的同时还需要进行叶轮的拆卸与安装。
3、 受外界天气的影响较大。 在更换叶轮时如果外界风力较大， 安装叶轮 则会较困难。 发明内容
