The invention discloses a hoisting and turning-over device and method for a rotor center body of a variable-speed pumped storage unit. The hoisting and turning-over device comprises a hoisting tool and a turning-over boot, the method comprises the steps that firstly, a lifting tool is installed at the upper end of a rotor center body, the lifting tool comprises a supporting side plate, a clamping piece and a lifting assembly, and the lifting assembly comprises a main lifting piece and two lifting hook pins installed on the main lifting piece; 2, installing a turning boot at the lower end of the rotor center body; and thirdly, the rotor center body is hoisted and turned over. The hoisting device is reasonable in structural design, the hoisting method is simple and convenient, the main hoisting piece and the clamping ring base are installed between the two supporting side plates, when the rotor center body is hoisted, a bridge crane main hook is directly hooked to a hoisting hook pin installed on the main hoisting piece, friction force of a steel wire rope and a hoisting lug is not needed, friction loss in the hoisting process is reduced, and the hoisting efficiency is improved. The hoisting efficiency is improved, so that the stress of the rotor center body is more uniform, the stability in the hoisting process is favorably kept, and the hoisting precision is improved.
本发明公开了一种变速抽水蓄能机组转子中心体起吊翻身装置及方法,该装置包括起吊工具和翻身靴;该方法包括步骤一、在转子中心体上端上安装起吊工具,起吊工具包括支撑侧板、卡装件和吊装组件,吊装组件包括主吊件和两个安装在主吊件上的吊钩销;步骤二、在转子中心体下端上安装翻身靴;步骤三、转子中心体起吊翻身。本发明结构设计合理,吊装方法简便,通过在两个支撑侧板之间安装主吊件和卡环底座,在进行转子中心体的吊装时,将桥机主钩直接勾设在主吊件上安装的吊钩销上,无需钢丝绳和吊耳的摩擦力,减少了吊装过程中的摩擦损失,提高了吊装效率,使得转子中心体的受力更加均匀,有利于保持吊装过程中的稳定性,提高了吊装精度。
