Description

Technical Field

[0001] The invention relates to the technical field of generator rotor manufacturing, and in particular to a generator rotor painting support tool and a use method thereof. Background Art

[0002] During the production of generators, the painting of the generator rotor is an important process. Currently, a crane is usually used to lift the generator rotor so that workers can paint the rotor from below. However, this traditional operation method has many serious problems.

[0003] On the one hand, during the operation of the crane, if the operator is not skilled or makes mistakes, it is very easy to cause the rotor to collide. For example, it may collide with surrounding equipment, building structures, etc., which will not only damage the expensive generator rotor, affect its mechanical and electrical properties, and thus reduce the overall efficiency and reliability of the generator, but the impact force generated by the collision may also damage the mechanical structure of the crane, shorten the service life of the crane, and increase maintenance costs.

[0004] On the other hand, if the rotor is not firmly fixed during the lifting process, there is a risk of falling at any time. Once the rotor falls, it will cause an extremely serious safety accident, posing a huge threat to the life safety of on-site workers, and will also cause serious damage to surrounding equipment and facilities, leading to production stagnation and causing immeasurable economic losses to the company.

[0005] In addition, during the painting process, the unstable state of the rotor being lifted makes it difficult to ensure the uniformity of the painting, which not only affects the appearance quality of the rotor, but also may affect its anti-corrosion and anti-rust properties due to uneven paint layer thickness, thus reducing the service life of the generator rotor.

[0006] In summary, the existing generator rotor painting method has serious safety hazards and quality problems, and a new type of generator rotor painting support tooling is urgently needed to solve these problems. Summary of the invention
