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] Refer to attached Figure 1 to Figure 7 .

[0029] The measuring device for the rotor bracket of the hydro-generator oblique rib support arm structure, including the base ring plate 2, the wide yoke yoke punching piece 8, and the stack inspection pin 6, and the height-adjustable The base ring plate 2, the height-adjustable base 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. There are stacking pins 6 on the base ring plate 2, and the wide yoke punches 8 are stacked to form a full-circle yoke ring 3, and the full-circle yoke ring 3 is stacked with 5-10 layers of ordinary Yoke punch 9. There is 30 ° of chamfers on the upper end of stack inspection pin 6 to facilitate the stacking of yoke punching sheets. There are bottom holes at the bottom of the vertical ribs of the rotor 10 support, and the full circle yoke ring has bolts 5 that are combined with the bottom hol...

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 hydroelectric generators, and in particular relates to a measuring device for a rotor support of a hydroelectric generator with an oblique rib support arm structure. Background technique [0002] At present, the design of the rotor support of the large-capacity tubular hydro-generator has been changed from the traditional web structure to the inclined rib support arm structure to meet the requirements of the rotor structure's operation stability and ventilation, 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 size of the outer circle and the large number of 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 ...
