Description
Technical field
The utility model belongs to power station turbine-generator units auxiliary equipment field, and in particular to a kind of power station water wheels hair
Steel wire rope barring gear is matched somebody with somebody in group of motors driving.
Background technology
There are multiple big axles to be connected in hydrogenerator, between rotor and runner, it is therefore desirable to by manpower to rotor
Rotate one week, to judge whether the load by motor driven has stuck and resistance increase situation, so as to which electricity will not be made
The startup load of machine becomes big and damages motor, and here it is the jiggering operation in hydrogenerator.Traditional middle-size and small-size hydraulic generator
Machine jiggering lifts by crane jiggering usually using Manual hand-push jiggering or steel cable, and electric barring is costly, and floor space is big, generally not
It is used.The mode operating difficulties of Manual hand-push jiggering, barring speed, jiggering low precision can be difficult to control；Traditional steel cable rises
Hanging scaffold car is difficult to accurately control hand turning tool to rotate a circle, and influences jiggering quality, and hand turning tool deadweight is larger, and mobile and installation is tired
It is difficult.
Utility model content
To solve the problems, such as that above technology is present, the utility model provides a kind of power station turbine-generator units driving and matches somebody with somebody steel
Cord barring gear, accurately hand turning tool can be controlled to rotate a circle, obtain whether the load of motor driven is normal, and raising jiggering is smart
Degree；Hand turning tool weight, which replies, to be mitigated, and intensity meets to require, convenient disassembly.
Its technical scheme is：
Steel wire rope barring gear is matched somebody with somebody in a kind of driving of power station turbine-generator units, including electric machine main shaft, connecting shaft, spindle nose,
Hand turning tool, assembly pulley, frame, fixing hole, steel cable and hook of driving a vehicle, are connected to connecting shaft on the electric machine main shaft, connect
Axle upper end is fixedly installed spindle nose, and hand turning tool is fixedly installed on the spindle nose, and the both sides setting of the electric machine main shaft is organic
Frame, fixing hole is provided with the frame of the both sides of electric machine main shaft, the steel cable is connected to the assembly pulley of fixing hole, described another
Root steel cable both ends are fixedly installed on hand turning tool, and assembly pulley and driving hook are passed through among another steel cable；
The hand turning tool includes retainer ring, tie-beam, jiggering circle, steel cable groove and connecting pin, and the retainer ring is fixed and set
To put on spindle nose, retainer ring is connected to jiggering circle by multiple tie-beams, is provided with two circle steel cable grooves on the outside of the jiggering circle, and two
Connecting pin is provided with circle steel cable groove, described two connecting pins are in through on the same plane in jiggering circle axle center.
Further, the junction of tie-beam and the jiggering circle is provided with reinforcement.
Further, more than one screwed hole is provided with the connecting shaft, push rod is provided with the screwed hole, it is described
Limiting card is provided with the frame of the both sides of electric machine main shaft；
The push rod includes expansion link, rod set, six prism telescopic sections and threaded rod, and described rod set one end is provided with screw thread
Bar, the rod set other end are connected to expansion link, and six prism telescopic sections on the expansion link are arranged in rod set, the threaded rod with
Screwed hole screw thread in connecting shaft coordinates.
After Medium and Small Hydraulic Generator shuts down a class, it is again started up before motor, it is necessary to carry out jiggering operation.Jiggering is opened
During the beginning, electric machine main shaft has been set with thrust collar, possesses the condition that rotating part weight is transferred to thrust bearing, internal rotor inspected
No-sundries, the air gap inspected no-sundries meet rotating part rotation condition.The Fixing shrink ring of hand turning tool leads on spindle nose
Cross and be bolted in connecting shaft.Retainer ring is connected to jiggering circle by multiple tie-beams, facilitate hand turning tool disassemble installation with
And maintenance is exchanged.After hand turning tool installation, connecting shaft is promoted using push rod, rotates hand turning tool, it is ensured that the company on jiggering circle
Pin is in same horizontal line with steel cable.Expansion link is now twitched, six prism telescopic sections in rod set is extracted certain distance out,
Six prism telescopic sections can use the spanner of dimension to rotate, and facilitate threaded rod to coordinate with the screwed hole in connecting shaft.Expansion link is taken out
Push rod is increased after going out, may be stuck in push rod by the jiggering after on the limiting card in the frame of the both sides of owner's axle, preventing adjustment
Rotation occurs for instrument.Then after steel cable is enclosed along the steel cable groove arrangement one on jiggering circle, it is fixedly connected on connecting pin, starts
Hook of driving a vehicle pulls, and steel cable is shut down after producing tension force, and shrinking expansion link makes push rod depart from limiting card, or the directly company of removing
Push rod in spindle, it is spacing to remove jiggering.Now restart driving hook and at the uniform velocity pull steel cable, steel cable passes through assembly pulley deflecting
Afterwards, horizontal to pull hand turning tool rotation, after connecting pin rotates a circle, the rotation of steel cable pulling force banking pin rotates, now disk
Turner tool rotates a circle, and jiggering rotating speed is uniform, and precision is high.Steel cable and assembly pulley can arrange that floor space is small according to site space.
The beneficial effects of the utility model：
The utility model is simple in construction, easy for installation, can be arranged according to site space, floor space is small；Jiggering mode is closed
Reason, accurately can control hand turning tool to rotate a circle, and whether obtain the load of motor driven normal, improve jiggering precision；Jiggering work
Have weight and reply mitigation, intensity meets to require, convenient disassembly.
