The invention discloses a wind driven generator blade lifting device with a protective structure, a positioning lantern ring and a connecting lantern ring are sleeved on the top of a stand column of a wind driven generator, and the positioning lantern ring is positioned on the stand column through a positioning bolt. The fixed base is movably sleeved with a rotating disc, the rotating disc is fixedly connected with the movable cross beam, and the cross beam driving mechanism drives the movable frame to move in the length direction of the movable cross beam; the lifting and hoisting mechanism is connected to the movable frame and used for hoisting the blade. A fixing rod of the blade protection structure and the lifting hoisting mechanism synchronously ascend and descend; the spring clamping mechanism provides clamping force for the two baffle connecting rods. At the beginning, the spring clamping mechanism drives the two protection baffles to be clamped and make contact to define a U shape. When the blade is lifted, the baffle connecting rod rotates to open the two protective baffles, and the spring clamping mechanism acts to enable the two protective baffles to clamp the blade. The hoisting device is prevented from shielding the blades of the generator, and hoisting, mounting and use of the multiple blades and adjustment of hoisting and mounting positions are facilitated.

    本发明公开了一种带有防护结构的风力发电机叶片起吊装置,其定位套环和连接套环套在风力发电机的立柱顶部,定位套环通过定位螺栓定位到立柱上。固定底座活动套接有旋转盘,旋转盘固定连接移动横梁,横梁驱动机构驱动移动框架沿移动横梁的长度方向移动;升降起吊机构连接于移动框架上并用以起吊叶片;叶片防护结构的固定杆与升降起吊机构同步升降;弹簧夹紧机构为两个挡板连接杆提供夹持力;初始时,弹簧夹紧机构驱动两个防护挡板夹紧并接触围成U型;起吊叶片时,挡板连接杆转动使两个防护挡板打开,弹簧夹紧机构作用使两个防护挡板夹紧叶片。本发明防止起吊装置对发电机叶片造成遮挡,便于多个叶片的起吊安装使用和调整起吊和安装的位置。
