Description
Technical field
This utility model is related to the technical field of wind-driven generator tower frame, refers in particular to a kind of Combined type wind power generation tower
Frame.
Background technology
In order to improve low wind speed area wind field exploitation economy, increase owner's income, need increase impeller diameter while
Improve hub height.It is computed, when hub centre highly brings up to 120 meters or so, can utilizing in year for some low wind speed regions is little
When number can reach 2,000 hours, with Development volue.There is when conventional steel tower height is below 90 meters larger cost
Advantage, while there is no road transport；And after working as tower height more than 90, pylon cost steeply rises, while bottom
Becoming large-sized causes transport difficult；In addition, steel pylon will become soft after doing height, and pylon natural frequency is in one times of wind wheel
Between frequency and frequency tripling, resonance harm is produced.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided it is a kind of it is rational in infrastructure it is reliable, economical and practical,
It is easy to the Combined type wind power generation tower frame for dismounting and transporting, has given full play to the performance of concrete and steel, overcomes steel tower
Cylinder rigidity is little, deform the problem of big, easy flexing, while pylon natural frequency is obviously improved.
For achieving the above object, technical scheme provided by the utility model is：A kind of Combined type wind power generation tower frame, it is main
To be made up of top steel tower and middle transition platform and bottom steel pipe concrete bracket；The upper surface of the transition platform
It is provided with for installing the upper flange of top steel tower, its lower surface is provided with for connecting bottom steel pipe concrete bracket
Lower flange, reinforced using ribs between the upper flange and transition platform；The bottom steel pipe concrete bracket
Mainly it is made up of many pillars, and be attached by bearing diagonal and flange between pillar two-by-two, in every pillar and bearing diagonal
Portion is perfused with concrete.
The upper and lower of the pillar is respectively welded the joint steel pipe with adpting flange, for connecting bearing diagonal, should
The horizontal flange of connection transition platform lower flange is fixed with the top of pillar；The bearing diagonal is by steel pipe main body and is loaded on the steel
The adpting flange composition at pipe main body two ends.
The main body of the pillar is conical steel pipe.
This utility model compared with prior art, has the advantage that and beneficial effect：
This pylon improves pylon using concrete by the way of conventional steel tower is combined with concrete filled steel tube pylon
Rigidity and frequency, reduce the deformation of pylon, overcome the problem that steel pylon is susceptible to local buckling.Bottom concrete filled steel tube
Part is made up of three pillars, is attached by bearing diagonal and flange, solves base diameter well excessive between pillar
And the transportation problem for causing.Using concrete g rill wall, with easy, cheap advantage of drawing materials；Meanwhile, it is filled in steel
The state of concrete in pipe in three dimension stress, it is to avoid concrete compression and the problem of Cracking that causes.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
As shown in figure 1, Combined type wind power generation tower frame described in the present embodiment is mainly by top steel tower 1 and middle mistake
Cross platform 2 and 3 three part of bottom steel pipe concrete bracket composition.After Fig. 2 is installed on concrete filled steel tube frame for transition platform
Schematic diagram, the structural representation of Fig. 3,4,5 for transition platform, the upper surface of transition platform 2 is provided with for installing upper steel
The upper flange 5 of tower processed 1, its lower surface are provided with for connecting the lower flange 7 of bottom steel pipe concrete bracket 3, on this
Reinforced using ribs 6 between portion's flange 5 and transition platform 2.Structural representations of the Fig. 6 for bottom steel pipe concrete bracket
Figure, steel pipe concrete bracket 3 are mainly made up of three pillars 4, and be attached by bearing diagonal and flange between pillar two-by-two,
Concrete is perfused with inside every pillar 4 and bearing diagonal.Structural representations of the Fig. 7 for pillar, the main body of pillar 4 is tapered steel
Pipe, the upper and lower of the conical steel pipe are respectively welded the joint steel pipe 10,12 of connection bearing diagonal 14, and joint steel pipe 10,
12 connection end is provided with adpting flange 11, and the connection end of joint steel pipe 12 is provided with adpting flange 13, the top of the conical steel pipe
Portion is fixed with the horizontal flange 9 of connection transition platform lower flange 7.Structural representations of the Fig. 8 for bearing diagonal, bearing diagonal 14 is by steel
Pipe main body and the composition of the adpting flange 8,15 loaded on the steel pipe main body two ends.
The parts of the present embodiment combinations thereof formula wind turbine tower are transported to after seat in the plane, first three steel tube concretes
The pillar 4 and three bearing diagonals 14 of native support 3 is assembled into an entirety (as shown in Figure 6) by flange bolt, is then pacified
Dress is fixed on seat in the plane, by way of flange bolt connects efficiently solves the oversized transportation problem for causing；From three
The entrance that the top flange face of pillar is located down concrete perfusion, install after concrete setting molding transition platform 2 and on
Portion steel tower 1, so as to form a combination pylon entirety.In steel pipe, fill concrete not only avoid the flexing of steel pipe,
The rigidity and frequency of pylon are improve simultaneously, reduce the deformation of pylon, and frequency adjusts very easy.
The examples of implementation of the above preferred embodiment only for this utility model, not limits of the present utility model with this
Practical range, therefore the change made by all shapes according to this utility model, principle, all should cover in protection domain of the present utility model
It is interior.
