Problems solved by technology

However, due to the large size of the outer circle and many equal parts of the vertical ribs, this kind of rotor bracket has high requirements for dimensional and shape tolerances, and it is difficult to detect. The repair rate in the power station assembly is very high, which affects the construction progress of the hydropower station.

Embodiment 1

[0028] Reference attached Figure 1 to Figure 7 .

[0029] The measuring device for the rotor support of the inclined vertical rib support arm structure of the hydro-generator includes the basic ring plate 2, the wide yoke yoke punching piece 8, and the overlap check pin 6. The height adjustable bottom of the outer circle of the vertical rib of the rotor support 4 The height-adjustable basic ring plate 2 is installed on a height-adjustable support, and the adjustable support is a height-adjustable pillar 1 structure composed of bolts and nuts. The base ring plate 2 has a stack inspection pin 6 to stack the wide yoke yoke punching sheet 8 into a round yoke ring 3, and the round yoke ring 3 is stacked with 5-10 layers based on the stack inspection pin 6 The yoke punch 9. The upper end of the stack check pin 6 has a 30° chamfer that is convenient for stacking of the yoke punching sheet. The bottom of the vertical rib of the rotor 10 support has a bottom hole, and the round yoke r...

Abstract

The invention relates to a device for measuring a rotor bracket of a hydrogenerator oblique stud support arm structure. The invention belongs to the technical field of hydrogenerators. The device for measuring the rotor bracket of the hydrogenerator oblique stud support arm structure has the characteristics that: the device for measuring the rotor bracket comprises a basic annular plate, a wide yoke rim sheet, and a laminated inspection pin; the height-adjustable basic annular plate is arranged on the external circle bottom of a stud of the rotor bracket; the basic annular plate is provided with the laminated inspection pin to laminate the wide yoke rim sheet into a full circle yoke ring; and an equally-dividing positioning frame is embedded in an internal circle yoke key groove of the laminated full circle yoke ring. The invention has the advantages of simple structure, convenient operation, safe use, reliable performance, precise detection and the like; the requirement of rotor assembling is guaranteed, the progress for detecting the rotor bracket of the hydrogenerator oblique stud support arm structure is greatly improved, the measurement fixture cost is saved, the smoothness of the rotor assembling is guaranteed, and the designing and manufacturing level and the production efficiency are improved.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic generators, and particularly relates to a measuring device for a rotor support of a hydraulic generator with an inclined vertical rib support arm structure. Background technique [0002] At present, the design of the rotor support of the large-capacity tubular turbine generator has been changed from the traditional web structure to the oblique rib support arm structure to meet the stability of the rotor structure and the ventilation requirements, while saving a lot of raw materials and reducing the amount of welding. , Its design is more scientific and advanced. However, due to the large outer diameter of the rotor bracket, the large number of vertical ribs, high dimensional tolerances and geometric tolerances, detection is very difficult, and the repair rate in power station assembly is high, which affects the construction progress of hydropower stations. Summary of the invention [0003] In order t...
