Description

Technical Field

[0001] This application relates to the technical field of support devices, and particularly to an anti-tipping support device for the outer guide vane ring. Background Art

[0002] The outer guide vane ring is a main component in the guide vane mechanism of a tubular hydro-generator unit. Its shape is a rotating body with a gradually decreasing cross-section curve from the water inlet and outlet ends. A large outer guide vane ring is generally a structure formed by four segments bolted together to form a complete circle. When a single segment is placed vertically with the small end facing up, although the overall center of gravity is within the downward projected sector cross-section and theoretically will not tip over, the upper nearly 1 / 3 part extends beyond the lower support surface. If it is subjected to a large external force and collision, it is prone to tipping over and causing accidents.

[0003] To prevent accidental tipping, channel steel or angle steel is usually welded at one end to the flow-through surface and the other end is supported on the ground, welded before inspection and removed after inspection. When the outer guide vane ring is placed vertically during the intermediate process after the flow-through surface is machined, it is also necessary to support it by welding channel steel on the flow-through surface until it is finally cut off. This process will cause surface quality damage to the flow-through surface, and for this reason, fitters need to further polish it to deal with the damage. At the same time, since channel steel and angle steel cannot be reused repeatedly for a long time, repetitive welding, cutting and other operations will bring a large amount of repetitive labor to workers, consume a lot of manpower and material resources, and thus increase the manufacturing cost of workpieces. It is not conducive to production and will also cause waste of resources. Summary of the Utility Model
