Abstract
The utility model relates to a generator rotor lifting appliance which is applied to lifting a rotor when a water-turbine generator set is mounted or overhauled in a power station. The generator rotor lifting appliance comprises a main shaft lifting sleeve, a main shaft clamping slot ring and a bolt I, wherein the main shaft clamping slot ring is fixed together with the main shaft lifting sleeve through the bolt I. The generator rotor lifting appliance is characterized by also comprising a lifting shaft I and a lifting shaft II; the lifting shaft I is provided with a lifting shaft clamping ring I; the lifting shaft II is provided with a lifting shaft clamping ring II; the lifting shaft I and the lifting shaft II are parallel to each other, and two ends of the lifting shaft I and two ends of the lifting shaft II are respectively fixed into lifting shaft holes of a supporting plate I and a supporting plate II through the lifting shaft clamping ring I and the lifting shaft clamping ring II by bolts II; the main shaft lifting sleeve, the supporting plate I and the supporting plate II are connected into a whole by virtue of a lifting appliance bracket; the lifting shaft I and the lifting shaft II are positioned right above the main shaft lifting sleeve. According to the generator rotor lifting appliance, the possible potential safety hazard caused by the use of a steel wire rope in the prior art can be avoided, and the work of manual steel wire rope winding is eliminated. During overhaul or mounting, the rotor is easy to lift, and the generator rotor lifting appliance is safe and reliable.
Description
Technical field
The utility model relates to generator amature suspender, is applied to hydraulic generator unit and when power station installation or maintenance, lifts by crane rotor.
Background technology
Hydraulic generator unit need to hang rotor when installing in power station or overhauling, and conventionally need to and hang rotor instrument by factory building suspension hook generator amature is sling.For medium-sized vertical shaft hydrogenerator unit, its generator amature weight is from tens tons to hundreds of ton, and rotor is installed, between turn(a)round, will repeatedly be lifted by crane, overturn, carry in power station.
Lifting rotor, adopts steel rope lifting conventionally.Steel rope one end is on the hanger of rotor lifter both sides, and the other end is on the suspension hook of factory building.Rotor lifter is comprised of suspender body, snap ring, bolt; It is upper that suspender body is enclosed within generator shaft lifting position, snap ring is stuck in the draw-in groove of main shaft, with bolt, snap ring is fixed on suspender body.During lifting, steel rope one end is on the hanger of suspender body, and one end is on suspension hook, and the displacement by suspension hook reaches the object that rotor is hung.
When lifted by crane rotor weight reaches ton up to a hundred when above, the wire diameter of steel rope will be selected greatlyr, and quantity also will be used often, makes the winding of steel rope very difficult, to crane lifting service, brings very large difficulty.Service life of steel wire rope, shortening, is used old steel rope also to have the potential safety hazard in lifting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of generator amature suspender steel rope, that directly go up factory building suspension hook that do not use is provided.
The purpose of this utility model can reach by following technical proposals: generator amature suspender, comprises that main shaft hangs position cover, main shaft bayonet slot ring, bolt I; Main shaft bayonet slot ring hangs position cover by bolt I and main shaft and fixes; It is characterized in that also comprising hanging axis I and hanging axis II; Hanging axis I band hanging axis snap ring I; Hanging axis II band hanging axis snap ring II; The hanging axis I being parallel to each other and hanging axis II, used bolt II that two ends are fixed among the hanging axis hole of stay bearing plate I and the hanging axis hole of stay bearing plate II by hanging axis snap ring I and hanging axis snap ring II respectively; Main shaft hangs position cover, stay bearing plate I, stay bearing plate II connect as one by suspender support; Hanging axis I and hanging axis II be positioned at main shaft hang position cover directly over.
Above-mentioned generator amature suspender, the two ends that it is characterized in that hanging axis I and hanging axis II are all connected by screw one and hold up handle.
The utlity model has following advantage: avoided using steel rope to bring possibility potential safety hazard in prior art, exempted the work of artificial lay winding wire ropes.The rotor of slinging in maintenance or installation is easy, safe and reliable.
