The invention belongs to the technical field of hoisting, and particularly relates to a large-tonnage wind power maintenance hoisting method which comprises the steps that a climbing mechanism is installed on the outer side wall of a wind power tower, and the climbing mechanism moves in the height direction of the wind power tower; a crane is installed on the operating platform, the operating platform is sent to the top end of the wind power tower through a climbing mechanism, the operating platform and the wind power tower are fixed, and a lifting hook of the crane extends out of the operating platform and is in transmission connection with a ground traction mechanism; a lifting hook of the crane falls to the ground through the ground traction mechanism, a lifted object is hung on the lifting hook of the crane, the lifted object and the climbing mechanism are bundled and fixed, the lifting hook of the crane is driven to ascend through the ground traction mechanism, and the lifted object is lifted to a designated position; and hoisting is completed. According to the method, the hoisting structure and the equipment cost investment are simplified, and meanwhile, adverse factors brought to the tower due to the huge eccentric acting force of the hoisted object in the climbing process of the hoisted object are avoided.
本发明属于起重技术领域,尤其涉及一种大吨位风电维修吊装方法,包括:在风电塔架的外侧壁上安装爬升机构,爬升机构沿风电塔架的高度方向移动;在操作平台上安装吊机,通过爬升机构将操作平台送往风电塔架的顶端并将操作平台与风电塔架固定,吊机的吊钩伸出操作平台,吊机的吊钩传动连接有地面牵引机构;通过地面牵引机构将吊机的吊钩下落至地面,将被吊物挂在吊机的吊钩上,并将被吊物与爬升机构捆扎固定,通过地面牵引机构驱动吊机的吊钩上升,将被吊物提升至指定位置;吊装完成。本方法在简化起吊结构和设备费用投入的同时,避免了被吊物在爬升过程中,因被吊物巨大的偏心作用力,给塔架带来的不利因素。
