Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.
According to inventive concept provided by the invention, as shown in Figure 1, 2, every two panels blade 1,2 is that one group of head and the tail is exchanged and is arranged side by side, by combinationally use at least two central supports 5,6, two limiting brackets 3,4, bandage, hanging beam 13 to be to carry out the transport of blade of wind-driven generator.
Fig. 3 shows the section drawing of one of them central support, this central support comprises two column jackets being positioned at both sides and the inner prop being positioned at centre, position between this inner prop and two column jackets is respectively used to fix same group of transported two panels blade, and is provided with for placing the fixing of blade and damping elastomer block 11,12.This column jacket top can be provided with the lifting point for hoisting blade.This central support also can arrange the parts such as connecting bore and detouchable guide finger, stacks to facilitate the fixing or layering of blade on transportation means.
Fig. 4 shows the schematic diagram of vane airfoil profile.Reference numeral 14,15 show respectively acting face and the suction surface of blade, and in the transportation resources of the specific embodiment of the invention, the two panels blade with group is preferably relative with respective suction surface and acting face is opposing mode is transported.
In the technical scheme of the specific embodiment of the invention, first, every two panels blade is that one group of head and the tail is exchanged and is arranged side by side, and is arranged side by side by the root of wherein a slice blade, makes two central supports be near two panels blade center-of-gravity station respectively with another sheet blade tip (afterbody) organized; Then, fixed carrying out binding between blade, central support and same group blade by bandage, and limiting bracket is arranged between root of blade and central support; Finally, use hanging beam by with on group leaf blade hanging to transport vehicle or on the deck of transport ship, transport after being connected and fixed.
When combining assembling, can consider blade is arranged in relative (acting face the is opposing) mode of respective suction surface, for the blade having pre-bending, when suction surface is relative, then blade tip pre-bending is outside, convenient like this binding.
According to the pre-bending deformation size of blade, the angular range of the root end face of blade and the cross-sectional plane of central support is 0 ~ 5 °, can reduce the van-type volume with group blade integral like this.
Blade maximum chord direction and horizontal surface angle are 30 ° ~ 80 °, to reduce the van-type volume with group blade integral.
The center-of-gravity position distance of central support position and blade is less than 5% of length of blade, if apart from excessive, needs the vehicle more grown during land transport, increases cost of transportation; Apart from too small, blade is when putting central support, and blade root is sagging, and blade tip can tilt, and binding difficulty, so often organizing blade integral stability will be poor.
Hanging beam is connected on the lifting point of central support, and deviation in range is less than 10% of the spacing of two central supports between hanging beam length and two central supports, to realize the integral hoisting of single group two panels blade, more promptly loading-unloading vehicle, the sea-freight of handling steamer, effectively can reduce the charge and discharge operations man-hour of blade, save shipping and delivery cost.
Central support bears blade Action of Gravity Field, and during terrestrial transportation, central support is fixed on the base plate of transport vehicle, and during sea-freight, central support is fixed in ship's deck.The top of central support has connecting bore simultaneously, and during sea-freight, central support can also use detouchable guide finger to be assemblied in the central support top of bottom blade, carries out layering and stacks.
Limiting bracket is used for the axial motion of stationary blade, abrades finish coat and the Structural layer of blade when preventing blade from transporting by land along the forward and backward slippage of vehicle heading, reduces the maintenance cost before blower fan installation.
Bandage by fastening with the two panels blade of group be overall, can prevent blade from sliding relative to central support, and blade pre-bending can be effectively reduced reduce shared volume when transporting.
Fixing and the damping elastomer block of central support can adopt the manufacture of the flexible material such as rubber, foam, its contact surface shape must be consistent with central support place blade inlet edge profile, localized contact stress can be reduced and absorb impact load blade produced because of road bump or the heave of waves, avoiding blade to sustain damage in transportation.
