The invention discloses a turning-over device and method for a runner plate of a water-turbine generator set. The turning-over device comprises a first hanging plate and a second hanging plate, and a plurality of sets of bolt holes are formed in the first hanging plate and the second hanging plate; a plurality of protruding blocks used for abutting against the runner plate are integrally formed on the first lifting plate and the second lifting plate, four lifting holes are formed in the first lifting plate and the second lifting plate, and the lifting holes are formed in the protruding blocks. The tool further comprises at least four sets of screw jacking mechanisms connected between the first lifting plate and the second lifting plate, and the screw jacking mechanisms are used for limiting the runner plate located between the first lifting plate and the second lifting plate in the radial direction. According to the turning device for the runner plate of the water-turbine generator set, the maintenance mode that the runner plate of the thrust block is turned over integrally can be replaced, that is, the runner plate of the thrust block with the weight of 12 tons is turned over independently, the runner plate of the thrust block with the weight of 80 tons is turned over integrally, the workload of assembling and disassembling the runner plate of the thrust block is reduced, and the working efficiency is improved. And the working efficiency of turning over the runner plate is also improved.
本发明公开了一种水轮发电机组镜板的翻身装置及翻身方法,该装置包括第一吊板和第二吊板,第一吊板和第二吊板上开设有多组螺栓孔;第一吊板和第二吊板上均一体成型有多个用于与镜板抵接的凸块,第一吊板和第二吊板上开设有四个起吊孔,起吊孔开设在凸块上;还包括连接在第一吊板和第二吊板之间的至少四组螺杆顶紧机构,螺杆顶紧机构用于对位于所述第一吊板和第二吊板之间的镜板进行径向限位。本发明提供的一种水轮发电机组镜板的翻身装置,可以替代推力头镜板一体翻身的检修方式,即采用对重量为12吨的镜板单独翻身取代了对重量达80吨的推力头镜板整体翻身,不仅减少了推力头镜板组装、分解的工作量,还提高了镜板翻身的工作效率。
