Description
Technical field
Overhaul of steam turbine field is the utility model is related to, more particularly to a kind of steam turbine rotor lifting tool.
Background technology
Steam turbine is mainly by cylinder, rotor, the stator blade in cylinder and the movable vane piece installed in rotor outer periphery
Form, develop with the maximization of steam turbine, turbine rotor is also increasingly heavier, and currently, the weight of turbine rotor is generally heavy
Up to 100~300 tons, therefore, when installing turbine rotor every time or carrying out overhaul of steam turbine, being required for will using lifting tool
Turbine rotor hangs out from cylinder or hangs in turbine rotor in cylinder.Especially, in lifting installation turbine rotor
During, it is necessary to accurately align turbine rotor levelness, avoid the stator blade in the movable vane piece and cylinder on turbine rotor
Piece occurs scraping collision, damages.
The lifting tool of lifting turbine rotor is presently used for as shown in Figure 1, it is mainly by girder 200 and installed in master
Steel wire rope 300 on beam 200 is formed.But during due to the foozle of girder 200, the error in length of steel wire rope 300, lifting
The factor such as operating error, the center of gravity of rotor 100 differs a distance with the lifting center of girder 200 after causing lifting, vacation
If the segment distance is 20mm；Exemplified by lifting by crane 100 tons of rotor, distance of the big suspension hook away from rotor axis of driving a vehicle is about 8.5m,
At this time, it is 0.135 ° to turn round oblique angle, then the difference of height of 100 or so omoplate of rotor is 20~25mm, as shown in Fig. 2, this is not fair
Perhaps.Therefore, have to carry out Levelling operation when lifting by crane rotor, ensure levelness of the rotor after lifting.
In the prior art, the mode for carrying out Levelling operation to rotor mainly has two kinds：Mode one, as shown in figure 3, in rotor
Level meter 400 is placed on 100, lifting point is moved left and right with the screw connection structure on girder 200；Mode two, as shown in figure 4,
Use the length with right-and-left threaded cord holder 500 adjustment steel wire rope 300.But all there are following for both leveling modes
Defect：Can not judge exactly before lifting rotor whether leveling, can only just can determine that whether rotor is adjusted after rotor lifting
It is flat, still, since rotor is very heavy, Levelling operation can not be just carried out at all during lifting, rotor can only be placed on bracket
On, loosen steel wire rope examination and adjust recur after screw thread or cord holder lifting, then by level meter observe rotor whether leveling, it is so heavy
Multiple circulation, until rotor leveling.Therefore, Levelling operation is very cumbersome, time-consuming and laborious, can not accurately ensure rotor after lifting
Levelness.
