The invention discloses a lifting device of a wind turbine generator set. The lifting device is installed on the basis of an original crawling ladder of a tower drum and used for carrying maintenancepersonnel to ascend and descend, the difficulty that the maintenance personnel arrive at a cabin is lowered, and cabin maintenance is facilitated. The lifting device can be installed in combination with the structure of the original crawling ladder of the tower drum of the wind turbine generator set, the original crawling ladder does not need to be disassembled, an elevator shaft does not need tobe additionally constructed, and the installation efficiency of the lifting device is improved. Compared with a dragging type lifting scheme in the prior art, the lifting device does not need a counterweight structure, the structure of the lifting device is further simplified, and installation and maintenance are facilitated.
本发明公开了一种风电机组的升降装置,通过在塔筒原有爬梯的基础上,安装升降装置用于搭载维护人员升降,降低了维护人员到达机舱的难度,便于开展对机舱的维护。本发明的升降装置能够结合风电机组塔筒原有爬梯的结构进行安装,不需要拆掉原有的爬梯,也不需要另外构建电梯井,提高了升降装置的安装效率。本发明的升降装置相较于现有技术中的拽引式升降方案不需要对重结构,进一步简化了升降装置的结构,便于安装和维护。
