Technical Field

The invention relates to the field of motor testing, in particular to a generator rotor balance supporting device and method.

Background

The generator rotor is one of the core devices in a generator plant, although the generator rotor has a large volume, the installation and the maintenance of the generator rotor are both used as precise devices, and the generator rotor is usually placed on an excitation end axis for a short time before penetrating into a stator, so that the coaxiality needs to be roughly adjusted. The conventional construction method is that the steel plate is hoisted by a crane, and after the basic coaxial center is adjusted, the steel plate is supported by a supporting pad method.

The inventor thinks that after the axis is adjusted by the crane, the supporting is carried out by a supporting pad method, and once the supporting mode is adopted, the adjustability of the outgoing line deviation is poor.

In the prior publications, for example, CN201820679449.9 is a steam turbine and generator rotor, a main shaft transportation support device, CN201220671768.8 is a large steam turbine, a blower, a generator rotor support parking rack, a CN201620916671.7 hydraulic generator rotor magnetic pole installation support rack, and CN201510754340.8 is a support rack device for small generator rotor maintenance, which all solve the technical problem, but the inventor thinks that the present invention is not beneficial to popularization and use.
