The invention discloses a hydro electric generating set large shaft lifting appliance and a lifting method. The bottom ends of a first vertical plate and a second vertical plate are fixedly connected through a bottom plate; the two ends of the lower portion of the first vertical plate and the two ends of the lower portion of the second vertical plate are symmetrically provided with screw connecting structures used for being connected with large shaft end screws in a matched mode. Pin penetrating holes are formed in the top of the first vertical plate and the top of the second vertical plate. Arc-shaped supporting seats are symmetrically fixed to the outer walls of the first vertical plate and the second vertical plate and located at the positions where the pin penetrating holes are located, an oil cylinder used for pushing the cylindrical pin is fixed to the tail end of the arc-shaped supporting seat on one side, and the tail end of a piston rod of the oil cylinder is detachably connected with the end of the cylindrical pin. The lifting appliance can be used for auxiliary lifting of a large shaft, in the lifting process, the pin penetrating action of a cylindrical pin is achieved through hydraulic driving, the traditional manual pin penetrating operation process is replaced, and the pin penetrating efficiency is effectively improved.

    本发明公开了水力发电机组大轴吊具及吊装方法,第一立板和第二立板的底端通过底板固定相连;所述第一立板和第二立板的下部两端对称设置有用于和大轴端头螺杆配合相连的螺杆连接结构;所述第一立板和第二立板的顶部设置有穿销孔;所述第一立板和第二立板的外壁上并位于穿销孔所在位置对称固定有弧形支撑座,其中一侧的弧形支撑座末端固定有用于推动圆柱销的油缸,油缸的活塞杆末端与圆柱销的端头采用可拆卸连接。吊具能够用于大轴的辅助吊装,在吊装过程中,通过液压驱动来实现圆柱销的穿销动作,替代传统的人工穿销作业过程,有效提高了穿销效率。
