Description
Technical field
The invention belongs to wind-driven generator technical group field, and in particular to a kind of wind power generating set impeller formal dress method.
Background technology
At present, wind-powered electricity generation industry wheel hub change oar is divided into electric variable pitch and hydraulic vane change, and two kinds of pitching manners have its advantage and disadvantage,
It is convenient during its in-site installation blade for electric variable pitch, but its stability is poor, and fault rate is high, thus steady in order to improve unit
Qualitative, many main engine plants use hydraulic vane change, but hydraulic vane change can only adjust 90 degree of scopes, and this is just proposed more to on-site hoisting
High requirement, there is constraint when live impeller is installed.Under the conditions of hydraulic vane change, the mounting means of wheel hub can be formal dress and
Anti- dress, it is anti-when filling wheel hub lifting impeller, it is auxiliary hang slipping tail be blade leading edge, during formal dress wheel hub lifting impeller, auxiliary slipping tail of hanging
It is the trailing edge of blade, both compare, and the anti-slipping tail blade inlet edge safety coefficient that fills is high, the problems such as in the absence of leaf destruction, deformation, but
This installation method slinger duration, what slinger's duration was brought is the increase of hoisting cost, during in order to reduce slinger and
Hoisting cost, then the lifting method using formal dress slipping tail trailing edge is needed, but this hanging method has leaf destruction, become
The risk of shape.
Therefore be badly in need of it is a kind of when can not only reduce slinger and hoisting cost, and also ensure reduce leaf destruction,
The wind power generating set impeller formal dress method of the risk of deformation.
The content of the invention
It is an object of the invention to provide a kind of wind power generating set impeller formal dress method, when can not only reduce slinger and
Hoisting cost, and also ensure the risk for reducing leaf destruction, deforming.
The invention provides following technical scheme：
A kind of wind power generating set impeller formal dress method, using impeller formal dress equipment, it is auxiliary that impeller formal dress equipment includes blade
Suspender, trailing edge protector, the main suspender of impeller and impeller formal dress frock are helped, and wind power generating set impeller formal dress method includes
Following steps：S1：The wheel hub of wind-driven generator is arranged in impeller formal dress frock；S2：Install three leaves successively on wheel hub
Piece, first, by the way that the line of the position of centre of gravity of blade auxiliary lifting appliance and the position of centre of gravity of blade is perpendicular with blade, and by leaf
Piece trailing edge protector is arranged on the trailing edge position of blade, secondly, after blade auxiliary lifting appliance is by being fixed on the blade of blade
Blade is lifted by crane on edge position, again, rotating vane, finally, blade is arranged on wheel hub；S3：Single 90 degree of branch blade feathering, directly
Feathering is completed to 3 blades；S4：The trailing edge position of one of blade is fixed by blade auxiliary lifting appliance, impeller master hangs
Tool passes through stationary hub, blade auxiliary lifting appliance and the main suspender matching occlusal equilibration impeller of impeller and completes the formal dress installation of impeller.
Preferably, the impeller formal dress frock in S1 is located at three frocks on the outside of frock main body including frock main body and ring
Supporting leg, wheel hub are located in frock main body, and the angle between any two frock supporting leg is 120 degree so that can save scene
Set-up time, in-site installation cost is saved, it also avoid that blade is installed in the air, greatly reduce the potential safety hazard of personnel.
Preferably, the section of frock supporting leg is right-angled trapezium, and section is the wider base of the frock supporting leg of right-angled trapezium
Fitted with frock main body, the wider base of frock supporting leg is connected with frock main body by bolt, so as to not only cause impeller
It is easier for installation, and more convenience in transport.
Preferably, it is connected between frock main body and wheel hub by bolt so that the connection between frock main body and wheel hub is more
Add conveniently.
The beneficial effects of the invention are as follows：
1st, because the appearance and size of traffic condition limits, cause wheel hubs transport of some main engine plants can only just transport, scene
Need to turn over wheel hub during anti-dress impeller, so as to add field installation time, the increase linear belt of set-up time is peace
This increase is dressed up, furthermore due to the radian of blade blade tip itself, in order to not allow blade tip to contact to earth, what the anti-frock filled often designed
It is very high, so as to add the risk of installation personnel, in order to solve this series of problems so that using wind-driven generator wheel hub just
Dress mode, i.e., wheel hub is placed in impeller formal dress frock, wheel hub scene is reduced work hours without turning over and frock, saving is hung
This is dressed up, and frock height can be reduced, enabling reduces the installation risk of installation personnel；
2nd, during due to being arranged on wheel hub in blade, after 90 degree of feathering, blade tip can be made upward, reduce scene
To the demand in place during installation, it is possibility to have effect reduces leaf destruction, the risk of deformation, while is also convenient for last impeller
The installation of kuppe drive end bearing bracket；
