The invention provides a large motor rotor drawing and penetrating device and method, and belongs to the technical field of motor maintenance, and the large motor rotor drawing and penetrating device comprises a main balance beam body, a hoisting unit, a first connecting rope, a second connecting rope and an extension connecting rod. According to the large motor rotor drawing and penetrating device and method provided by the invention, the extension connecting rod penetrates through the mounting hole in the motor stator, the end part of the extension connecting rod is fixedly connected to one end part of the motor rotor, and then the first connecting rope is connected to the end part of the extension connecting rod, and the second connecting rope is connected to the end part of the motor rotor; the main balance beam body is connected with the motor rotor and the extension connecting rod, and finally the motor rotor is pulled through the hoisting device. According to the utility model, through the supporting cooperation of the main balance beam body and the extension connecting rod, the motor rotor can be drawn and penetrated only by using one hoisting device, the occupied field area and the number of personnel in the motor maintenance process are reduced, the drawing and penetrating efficiency of the motor rotor is improved, and the motor maintenance speed is improved.
本发明提供了一种大电机转子抽穿装置及方法,属于电机维修技术领域,包括主平衡梁体、起吊单元、第一连接绳、第二连接绳以及延长连接杆。本发明提供的大电机转子抽穿装置及方法,可以通过将延长连接杆穿过电机定子内的安装孔,再将延长连接杆的端部连接固定到电机转子的一个端部,然后分别将第一连接绳连接在延长连接杆的端部第二连接绳连接在电机转子的端部,实现主平衡梁体与电机转子以及延长连接杆的连接,最后通过吊装装置来实现电机转子的抽穿。可以仅通过主平衡梁体与延长连接杆的支撑配合,仅使用一个吊装装置即可实现电机转子抽穿,减小了电机维护过程中所占用的场地面积与人员数量,提高了电机转子的抽穿效率,提高了电机维修速度。
