Jiggering hydraulic jack withstand on disk move steam turbine main shaft when, hydraulic locking apparatus is held out against, and steam turbine main shaft is with hydraulic lock
Tight device is rotated.When jiggering hydraulic jack withstands on contraction, hydraulic locking apparatus is in relaxed state.Utilize jiggering hydraulic jack
The convergent force on top pulls hydraulic locking apparatus toward revolution, circularly works in cycles in this way, steam turbine main shaft just with
Rotation, moves up with regard to automatic domain.
The present invention solves the problems, such as that disk moves turbine rotor and must use crane, and other works are made to just vacate crane
Industry makes other operations no longer be stagnated when steam turbine is installed, while also solving crane steam turbine cannot when doing other operations
The problem of disc rotor.The total lever factor for effectively shortening steam turbine profession construction, accelerates construction speed, has filled up and used it in decades
The construction blank of its method disk turn is made that outstanding contributions for power construction cause, has good economic benefit and pushes away
Wide foreground.
Four, it illustrates：
Fig. 1 is the structural diagram of the present invention.
In figure：1--- hydraulic power units, 2--- driving devices conveying oil pipe, 3--- jiggering hydraulic jacks, 4--- spud piles,
5--- chains fix transverse slat, 6--- steam turbine main shafts, and 7--- locks chain, 8--- jiggering traction chains, and 9--- locks hydraulic pressure thousand
Jin top, the first chain connectors of 10---, the second chain connectors of 11---, 12--- jiggerings return to chain, 13--- locking devices
