Description
Technical field
The utility model belongs to technical field of hydroelectric generation, is related to hydro-electric power generating equipment maintenance dismounting, specifically a kind of use
Installation carriage is dismounted in the big component of the stator of heavy stay column sets turbine-generator units.
Background technique
China's water conservancy is fast-developing in recent years, has built the tubular power station of large quantities of low water head big flows.Through-flow
Formula unit equipment volume is big, and structure is complicated.To ensure that unit is stable and power generation production safety, Hydropower Plant not timing are big
Repairing is a routine work, and overhaul removes and installs the stator of hydrogenerator and other components are the links that need not can lack.
Every unit has the big component such as stator,, need to be by all parts since hole for hoist size is limited in unit equipment installation process
It successively hangs in runner, then is assembled respectively.The components such as stator, rotor, the light bulb head of bulb-type tubular hydro set are all to pass through lifting
Hole hangs in what runner was installed.Since flow channel space is limited, component hangs in sequence and is followed successively by light bulb head, rotor, stator, then
Rotor, stator installation are successively carried out, finally light bulb head assembly is installed in place.
For the hydraulic generator stator internal diameter of one of large-scale bulb-type tubular hydro set fixation member up to several meters of even more than ten rice, weight is high
Up to over one hundred ton.Unilateral general only more than ten millimeters of the air gap of stator and rotatable parts rotor.After rotor is in place, workshop is utilized
The specific purpose tool that bridge machine hangs out frame outer wall slowly transfers stator.Stator must the progress of horizontal direction downstream rotor side when installing
It is mobile, to be set with rotor.As the stator of hollow structure, its base outer wall is hung for a long time and easily occurs being permanently deformed in turn
Influence stator circularity.The slight shaking of stator easily causes stator and rotor collision to damage stator core and rotor magnetic in suit
Pole.To guarantee the air gap between generator stator and rotor, stator circularity need to carry out shaping with tens of groups of jack after suit, fixed
Son and rotor suit process time-consuming are very long, thus expend a large amount of working hours, and installation quality is not easy to guarantee.
Traditional lifting mode is: the specific purpose tool of stator outer wall suspended in midair using workshop bridge machine and rotor is set with,
The stator of hollow structure is unavoidably deformed, and the wirerope movement for suspending stator in midair has shaking, therefore stator and rotor
Suit process it is very slow, and stator and rotor the air gap situation need to be monitored at any time.Generally it will appear after stator installation is in place
The case where circularity changes must be adjusted stator circularity after the completion of suit.It, need to be with greatly when adjusting stator and rotor the air gap
The jack pair stator circularity of amount carries out shaping, and adjustment process is very difficult, and time-consuming, more important is be difficult to ensure stator
Installation quality.
Traditional lifting adjusts the position of the lifting big component of stator, for ruler using the method for steel wire hang completely
Extremely difficult control when lifting of very little and big weight stator component, needs that stator component could be hung to pre-determined bit by adjustment repeatedly
It sets, thereby results in stator component suspention overlong time, easily generation deformation.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of for heavy stay column sets hydrogenerator
