Description
Technical field
The present invention relates to a kind of wind-driven generator unit single blade mounting hanger, especially it is a kind of simultaneously suitable for double-fed and
The suspender of the single blade installation of straight drive blower, belongs to wind electricity blade hoisting technology field.
Background technology
In recent years, wind-power market is fast-developing.Generally, straight drive blower does not have gear-box, therefore can not carry out
Jiggering makes blade on the type for not possessing jiggering, it is necessary to by 30 ° of blade lean, realizes that single blade lifts.
The various wind electricity blade hoisting mechanisms occurred in the market.The hoisting mechanism cost is high, and function is single,
Stability is poor, does not possess 30 ° of functions of tilting installation single blade.
Therefore, a kind of suspender simple for structure is designed, in-site installation convenient disassembly, double-fed and straight wind dispelling can be realized simultaneously
The single blade lifting of machine.Pass through the flexible of dump ram, you can the change of main arm and main beam angle is realized, so as to realize leaf
The change of pitch angle that -30 ° in the air~30 ° of piece, it can realize that single blade lifts on the type for not possessing jiggering.
The content of the invention
The present invention is to solve to lift problem to solve wind power generating set single blade, not possessing jiggering function especially
Blower fan single blade lifting problem, and provide a kind of wind power generating set single blade mounting hanger, pass through stretching for dump ram
Contracting, you can realize the change of main arm and main beam angle, so as to realize the change of pitch angle of -30 ° in the air~30 ° of blade, lead to
Cross adjustment oil cylinder and clamping cylinder stretches to realize upper clamp and lower clamp closure and angle adjustment.
To achieve these goals, the technical solution adopted by the present invention is：A kind of wind power generating set single blade installation is hung
Tool, there are a main beam, a main arm and two blade clamping devices, the main arm is arranged in the middle part of main beam,
Main arm bottom is supported on main beam bottom by bearing pin, and can be rotated around bearing pin, between the main arm and main beam
Dump ram is also equipped with, dump ram both ends are respectively hinged on the lower end of main beam and the middle part of main arm, main beam both ends
Blade clamping device is respectively provided with, by the flexible lifting angle to adjust between main arm 2 and main beam of dump ram, so that
Realize the change of pitch angle of -30 ° in the air~30 ° of the blade clamped in blade clamping device；The blade clamping device is by adjusting
Oil cylinder, clamping cylinder, upper clamp, lower clamp composition；It is respectively hinged between the upper clamp and lower clamp in clamp column, it is described
Clamping cylinder and adjustment oil cylinder, the adjustment oil cylinder both ends point are respectively provided between upper clamp and lower clamp rearward end and clamp column
It is not hinged on clamp column top and lower clamp rearward end, the clamping cylinder both ends are respectively hinged in the middle part of clamp column and upper folder
Clamp in rearward end；The upper clamp and lower clamp realize that closure and angle are adjusted by adjusting the flexible of oil cylinder and clamping cylinder
It is whole.
Upper clamp and lower clamp in the blade clamping device are detachable clamp, can be selected according to different airfoil profiles
Different clamps.
The adjustment oil cylinder and clamping cylinder are equipped with mechanical lock, after preventing upper clamp and lower clamp clamping blade
Loosen.
The main beam is connected by flange face and bolt with blade clamping device, facilitates in-site installation to dismantle and transport
It is defeated；Balancing weight is housed on the main beam both ends.
The beneficial effects of the invention are as follows：
1. simple for structure, reliability is high
This hanger structure is succinct, and using being welded, girder is connected main frame with the grip unit of both sides by flange face.
Overall structure need to dismount part, in-site installation convenient disassembly with other.Adjustment oil cylinder, clamping cylinder, upper and lower tongses can clamp
Blade, everything are all completed by six oil cylinders.And critical oil cylinder is equipped with mechanical lock, ensure oil cylinder posture in the air.
Main beam is single welding structural element, reduces suspender deadweight to a greater extent.
2. possessing the function of -30~30 ° of installation blades, the single blade lifting of double-fed and straight drive blower can be realized simultaneously.
Pass through the flexible of dump ram, you can the change of main arm and main beam angle is realized, from realizing -30 ° in the air~30 ° of blade
Change of pitch angle.Because straight drive blower does not have gear-box, therefore can not carry out jiggering, 30 ° of blade lean can not have
On the type of standby jiggering, realize that single blade lifts.
3. scissor clamp structure, make blade installation/clipping operation simple and reliable
Clamping cylinder is used to control blade folder to clamp and open, and equipped with mechanical lock, can ensure that blade folder clamps leaf
Any loosening is not had after piece, avoids clamping, the lifting device of complexity, while adjusts oil cylinder to realize leaf angle degree
Fine setting, improve the efficiency of suspender clamping blade process.
4. applicability is wide, the installation of a variety of blades can be used
5. counterweight is adjustable, influence of the reduction blade center of gravity to lifting stability.
