Concave portion 25 is formed with, axis pin 7 is arranged in concave portion 25.Preferably, the first lug boss 21 and the second lug boss 31 respectively by
Two pieces of protrusive boards are formed.Preferably, the front end concave portion 23 and the first above-mentioned lug boss 21 that upper plate 2 has in front end form recessed
It can be same concave portion to enter portion 25, and the rear end concave portion 24 and the second above-mentioned lug boss 31 that lower plate 3 has in rear end are formed
Concave portion 25 or same concave portion, as long as being arranged on concave portion and connecting the first telescoping member 4 respectively (or second stretch
Contracting component 5) it is mutually non-interference with the axis pin of elastic component 6, so as to reduce the installation space to axis pin, simplify hinge
The design of structure.
Preferably, the first telescoping member 4, the second telescoping member 5 and elastic component 6 can be cylinder or hydraulic cylinder.
At this point, the working medium pressure in cylinder or hydraulic cylinder can be adjusted by pressure control device, so that its elongation or contracting
It is short.
Each component of the hinge arrangement of the utility model is not limited to axis pin connection, can also pass through bolt or other connectors
Connection, as long as hinged between can ensureing component.
As depicted in figs. 1 and 2, the center of upper plate 2 can form the first opening 22, and the center of lower plate 3 can be formed opens with first
It is flexible to be preferably symmetrical arranged first in the both sides of the first opening 22 and the second opening 32 at this time for 22 corresponding second opening 32 of mouth
Component 4, the second telescoping member 5 and elastic component 6.First opening 22 and the second 32 peripheries of opening may be provided with multiple be used for
Connect the mounting hole 40 of other components.The number and shape of mounting hole 40 setting can according to the structure of practical connecting elements come
It is configured.Similarly, the first opening 22 and the second opening 32 are not limited to circle as depicted in figs. 1 and 2, can be according to reality
The structure of connecting elements is configured.
When cabin and tower that the hinge arrangement for wind power generating set of above-mentioned composition is installed on to wind power generating set
When between cylinder, as shown in figure 3, the bottom of cabin 8 can be bolted to the upper surface of upper plate 2, and by the top of tower 9
Portion's (for example, top flange of tower) is bolted the lower surface of lower plate 3, and the fixed form other than bolt can also be used,
As long as play the role of firm fixed.Hinge arrangement state in unit running process is as shown in Figure 1,3 base of upper plate 2 and lower plate
This keeping parallelism, when tower 9 is shaken, hinge arrangement can pass through the first telescoping member 4, the second telescoping member 5 and elastic structure
Part 6 absorbs the vibrations of tower 9, and entire cabin 8 and upper plate 2 are together in the first telescoping member 4, the second telescoping member 5 and front and rear
It floats under the support of telescoping member 6, using the damping action of the working medias such as hydraulic oil, buffers between original cabin 8 and tower 9
Impact and vibrations, achieve the purpose that damping and reduce impact so that cabin 8 still keeps stable state.Also second can be omitted
At least one of telescoping member 5 and elastic component 6 can also play cushioning effect in this case.
As shown in figure 3, due to the pre- bending deformation of blade 10, it is close to tower when blade 10 is even at state vertically downward
The part at bottom still farther out, is unfavorable for the maintenance of blade 10 with a distance from tower.However, in the hinge arrangement for being mounted with the utility model
Wind power generating set in, when needing to safeguard blade 10, the expanding-contracting action of telescoping mechanism can be passed through so that 2 He of upper plate
Lower plate 3 is in predetermined inclination, consequently facilitating being safeguarded.At this point, as shown in Fig. 2, the first telescoping member 4 extends, the second flexible structure
Part 5 and elastic component 6 shorten, and the angle between upper plate 2 and lower plate 3 becomes larger, and upper plate 2 is tilted towards front.Therewith, as schemed
Shown in 4, cabin 8 can be as the angle between upper plate 2 and lower plate 3 becomes larger and turns forward, and the blade 10 mounted on 8 head of cabin exists
It, can be close to the reduction of the distance between tower 9, tower 9 close to the part of bottom of towe so that need to tie up when turning to tower position
The blade 10 of shield is vertically downward close to tower wall.Staff only need to be from the barrel of the tower 9 of following relatively low one section of climbing in this way
It can safeguard blade 10, come without using other device close to blade 10, so as to facilitate the maintenance of blade 10.Hinge arrangement institute
Without too big, guarantee 8 normal elbow of cabin because wind generator set blade 10 is longer, only needs the angle of generation
Superposed hinge arrangement is wanted to generate a smaller angle and may be such that barrel of the blade 10 close to tower 9.Blade 10 should
Close proximity to tower 9 in order to safeguard, but interference cannot be generated with tower 9.Blade 10 is needed when safeguarding blade 10 vertically downward,
Blade tip is directed toward ground.
First telescoping member 4, the second telescoping member 5 and the flexible of elastic component 6 can pass through hydraulicdirectional control valve
It realizes.For example, artificially providing transmission signal, stretched by manual adjustment reversal valve, when needing to tie up in stopping process
Hydraulicdirectional control valve (may be provided at engine room inside) is adjusted when protecting blade can be so that the elongation of the first telescoping member 4 be stretched while around
Contracting component 6 shortens so that unit is in maintenance state as shown in Figure 4.
The utility model is not limited to the above embodiments, for example, can also using elastic damper instead of cylinder or hydraulic cylinder come
The first telescoping member 4, the second telescoping member 5 and elastic component 6 are made, so as to play the role of bumper and absorbing shock.As long as
It disclosure satisfy that the intensity requirement of support 8 total weight of cabin, while disclosure satisfy that and absorb impact endurance test shock when cabin 8 is shaken under wind load
Effect.
In addition, front with set respectively in the left and right sides 4, second telescoping members 5 of first telescoping member and
It is illustrated for one elastic component 6.But the first telescoping member 4, the second telescoping member 5 and elastic
The quantity and installation site of component 6 are not limited to diagramatic way, can suitably adjust as needed.
Moreover, the link position of the first telescoping member 4 and upper plate and lower plate is not limited to rear end, it also can be at middle part or by nearby
End.
In addition, though be illustrated by taking the situation that hinge arrangement is installed between cabin and tower as an example, but this reality
Between other two connectors being can also be applied to novel hinge arrangement.
Moreover, in the case where not departing from the scope of the utility model, various changes and modifications can be carried out.
