7MW, the water energy total amount than that can be developed on the earth are also big 10 times.
The body of work part of wind-driven generator includes flabellum and blower fan main shaft, and the tail end of flabellum is fixed on blower fan main shaft
On.Big blower fan needs two crane installations when mounted, very inconvenient.If with a crane, it is necessary to there is a fixed dress
Put the flabellum of fixed big blower fan.
The content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of fixed dress of fixed fan leaf
Put, by setting main shaft installing mechanism to fix blower fan main shaft, fan leaf is fixed by blade installing mechanism, in installation blower fan
When, it is only necessary to a crane is very convenient with regard to operable.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
Fan leaf fixing device, including for installing the main shaft installing mechanism of blower fan main shaft and being arranged on main shaft fitting machine
The blade installing mechanism of structure side, the blade installing mechanism have three, set between three blade installing mechanisms in 120 ° of intervals
Put.The utility model fixes fan leaf by setting main shaft installing mechanism to fix blower fan main shaft, by blade installing mechanism,
When blower fan is installed, it is only necessary to which a crane is very convenient with regard to operable.120 ° of accurate positioning, avoid artificial check and correction angle
Error.
Preferably, the main shaft installing mechanism includes central shaft and the mounting flange of centrally disposed axle upper end, institute
State and two groups of predetermined holes are offered on mounting flange, two groups of predetermined rounded arrangements in hole, and the circular circle of two groups of predetermined hole compositions
The heart is identical.By setting two groups of predetermined holes to be used to fix blower fan main shaft now on center shaft.
Preferably, the blade installing mechanism includes being fixed on one section of main shaft installing mechanism side canned paragraph, the side of passing through
Two sections of horizontal segments that shape flange is fixedly connected with one section of canned paragraph and three sections of arcs that two sections of horizontal segments are fixed by square flange
Section and the four sections of horizontal segments fixed with three sections of segmental arcs by square flange, are provided with four sections of horizontal segments for controlling this
The hydraulic mechanism of fixing device lifting.Because the volume of big blower fan is very large, so must dismantle in transit, the application is led to
Setting hydraulic mechanism is crossed, conveniently regulation can be lifted, and blade installing mechanism is made up of multistage, dismounting position is designed into position, tears open
Unload easily, convenient transportation.
Compared with prior art, the beneficial effects of the invention are as follows：
1. the utility model fixes blower fan by setting main shaft installing mechanism to fix blower fan main shaft, by blade installing mechanism
Flabellum, when installing blower fan, it is only necessary to which a crane is very convenient with regard to operable.120 ° of accurate positioning, avoid artificial school
Angle is malfunctioned.
2. because the volume of big blower fan is very large, so must dismantle in transit, the application is by setting hydraulic press
Structure, conveniently regulation it can lift, and blade installing mechanism is made up of multistage, dismounting position is designed into position, and dismounting is easy, transporter
Just.

Between in 120 ° interval setting.The utility model passes through blade fitting machine by setting main shaft installing mechanism to fix blower fan main shaft
Structure fixes fan leaf, when installing blower fan, it is only necessary to which a crane is very convenient with regard to operable.120 ° of accurate positioning, keeps away
Artificial check and correction angle error is exempted from.
Main shaft installing mechanism 1 includes the mounting flange 4 of central shaft 3 and the upper end of centrally disposed axle 3, on mounting flange 4
Two groups of predetermined holes 5, two groups of predetermined 5 rounded arrangements of hole are offered, and the circular center of circle that two groups of predetermined holes 5 form is identical.
Blade installing mechanism 2 includes being fixed on one section of 1 side of main shaft installing mechanism canned paragraph 6, passes through square flange 7 and one
Two sections of horizontal segments 8 that section canned paragraph 6 is fixedly connected, the three sections of segmental arcs 9 fixed by square flange 7 with two sections of horizontal segments 8 with
And the four sections of horizontal segments 10 fixed with three sections of segmental arcs 9 by square flange 7, it is provided with four sections of horizontal segments 10 for controlling
The hydraulic mechanism 11 of fixing device lifting.Because the volume of big blower fan is very large, so must dismantle in transit, this Shen
Please by setting hydraulic mechanism, conveniently regulation can lift, and blade installing mechanism is made up of multistage, dismounting position is designed into
Position, dismounting is easy, convenient transportation.
Above content described in this specification is only to the utility model example explanation.The utility model
