Abstract

The invention relates to a hoisting and transporting device of an electric motor rotor, which relates to a device for hoisting and transporting the electric motor rotor during assembly. It mainly solves the problem that the laminated rotor needs to be press-fitted and dynamically balanced in the assembly process. At present, these processes are carried out by two people working together to lift the rotor to the target position and press-fit or dynamically balance the rotor. High labor intensity, low working efficiency and high risk factor are solved. The lifting device of the invention is thata lifting ring is arranged on the sealing end of a circular steel pipe with one end sealed and one end opened, and a round nut is fixed in one end of the circular steel pipe opening. Two round nuts are screwed on the matching thread of the rotor rotating shaft, the lifting ring is hung on the lifting hook of the sling, and the motor rotor can be lifted and transported through the sling. The invention can be operated by only one person, has high working efficiency, low labor intensity, safety and reliability, and ensures that the rotor is not damaged in the handling process.

Description

technical field [0001] The invention relates to a lifting and transporting device for a motor rotor, in particular to a device for lifting and transporting a motor rotor during assembly. Background technique [0002] Motor assembly can be divided into three stages: stator assembly, rotor assembly and final assembly. For the laminated rotor, in the rotor assembly, it needs to be press-fitted and dynamically balanced. These processes all involve the lifting and handling of the motor rotor. For the weight of the rotor below 40KG, the specific operation when moving and storing it in a small area is that two people work together to lift the rotor to the target position, and perform operations such as pressing or dynamic balancing; the disadvantages are: ①High labor intensity and waste of manpower;② Two people are required to cooperate to complete the work together, and the work efficiency is low; ③There is a risk of falling when carried by two people, the risk factor is high, an...
