Description

Technical Field

[0001] The utility model relates to the field of steam turbine generators, in particular to a transition manifold structure for segmented transportation of a steam turbine generator stator. Background Art

[0002] At present, the stator bars of large-capacity steam turbine generators in China are generally water-cooled, and manifolds fixed to the machine base are arranged at both ends of the stator. When the stator is transported as a whole, the transportation method and route are limited by the size and weight of the stator, and the stator can be changed to segmented transportation. At this time, the manifold extends out of the middle section of the stator and cannot be fixed to the side section machine base. The transition manifold structure of this application can meet the needs of segmented transportation. Utility Model Content

[0003] In view of this, the purpose of this utility model is to disclose a transition manifold structure suitable for stator segment transportation, which is used to add a supporting structure to the middle section of the stator to temporarily fix the manifold during transportation.

[0004] The technical solution of the utility model is that it consists of a manifold, a middle section connecting block, a side section connecting block, a middle section supporting plate, a side section supporting plate, an adjusting gasket, a pressure ring, a connecting pin, a middle section machine base and a side section machine base; when the generator stator is transported in sections, the manifold is connected and fixed to the pressure ring inside the middle section machine base through the middle section connecting block, the middle section supporting plate, the adjusting gasket and the connecting pin; when the segmented stator is assembled, the manifold is connected and fixed to the side section machine base through the side section connecting block, the side section supporting plate and the connecting pin.

[0005] As a preferred embodiment, the middle section connecting block and the side section connecting block are fixed to the manifold by welding, the middle section support plate is fixed to the pressure ring by welding, and the side section support plate is fixed to the side section machine base by welding.

[0006] Technical effects:

[0007] 1. In the present invention, the support plates are welded according to the actual assembly position, which can effectively reduce the difficulty of manifold assembly.

[0008] 2. In the present invention, the thickness of the adjusting gasket of the manifold is processed according to the actual assembly situation, which can effectively absorb the length deviation during the welding and processing of the side section machine base. BRIEF DESCRIPTION OF THE DRAWINGS
