Description
Technical field
Fields of measurement is installed the invention belongs to metal structure and the accurate of component, and in particular to one kind tracks skill based on laser
The large scale hydraulic generator stator of art installs measuring method, is installed applied to large scale hydrogenerator with detecting accurate measurement
In.
Background technology
At present, laser tracker is applied to industrial machinery manufacture installation with detecting in work more and more widely,
In the more production for being applied to the large scale structures such as aircraft manufacturing, shipbuilding of China, installation process, but answering in hydropower industry
With also less, precedent is there is no in being installed applied to Hydropower Unit.We introduce Leica AT402 laser trackers（Measurement is nominal
± (15 μm+6 μm/m of precision））, using its high-precision advantage, overall application is installed in measurement in turbine-generator units stator,
Achieve good effect.
Because Hydropower Unit stator installation accuracy requires very high, the positional accuracy requirement of surveying and locating is less than 0.1mm.Tradition
Stator install control accuracy measurement means around survey round frame expansion, survey round frame one be processing and installation accuracy require
It is high；Two be that build is huge, is installed and adjustment is time-consuming takes a lot of work；Three be that measurement efficiency is low and precision controlling difficulty is big.And laser is tracked
