The invention belongs to the technical field of nuclear power station nuclear pump maintenance engineering, and particularly relates to a vertical motor rotor hoisting and overturning device and method. The device comprises a shaft head lifting appliance and a rotor hoop, wherein the shaft head lifting appliance comprises baffles a, rotating sleeves, a spacer, a boundary lubricating bearing, baffles b, a screw and a connecting plate; a shaft head lifting appliance body is a yoke plate; the baffles b and the rotating sleeves are sequentially installed on the positions, close to the shaft head connecting positions, on two sides of the yoke plate; and the baffles a are installed on the outermost sides. According to the vertical motor rotor hoisting and overturning device and method provided by the invention, sliding friction between a lifting belt and the shaft head lifting appliance during overturning is reduced, the shaft head lifting appliance and the lifting belt are protected, damage is reduced, the service life of the lifting belt and the shaft head lifting appliance is prolonged, axial limiting of the rotor hoop is increased, axial sliding of the rotor in the overturning process is avoided, and the risk of hoisting operation is reduced.
本发明属于核电站核级泵检修工程技术领域，具体涉及一种立式电机转子吊装及翻转装置及方法，该装置包括轴头吊具和转子抱箍；其中，轴头吊具包括挡板a、旋转套、隔垫、边界润滑轴承、挡板b、螺钉和联板；轴头吊具主体为联板，联板两侧靠近轴头连接位置依次安装挡板b和旋转套，在最外侧安装挡板a。本发明减小翻转时吊带与轴头吊具间的滑动摩擦，对轴头吊具与吊带起到保护作用，减少损坏，延长吊带与轴头吊具的使用寿命，增加了转子抱箍的轴向限位，避免了转子翻转过程中的轴向滑动，降低了起重作业风险。
