6 and 7 are reference diagrams for explaining the action of the blade transport trailer for wind turbines according to the present invention.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
2 to 7 shows a blade transport trailer for a wind turbine in the present invention, the support frame (2) which is extended in the front and rear direction so that the front end is pivotally connected to the rear side of the trailer truck (1); , A plurality of rear wheels 3 provided on the rear side of the support frame 2, and fixing means 4 provided on an upper surface of the support frame 2 to fix the blades 5. Fixing with the fixing means 4 with the proximal end of 5) facing forward is the same as in the prior art.
At this time, as shown in Figure 4, the base portion of the blade 5, a flange portion 5a for coupling to the rotating shaft provided in the hub of the wind power generator is formed, the flange portion 5a through the front and rear surfaces A plurality of through holes 5b are formed.
In addition, according to the present invention, the fixing means 4 is hinged to the support panel 10 provided on the upper surface of the support frame 2 and the support panel 10 to be rotatable in the vertical direction and the blade Rotating panel 20 and the both ends are connected to the support panel 10 and the rotating panel 20 to secure the proximal end of (5), and rotates the rotating panel 20 in the vertical direction according to the stretching action. It consists of a hydraulic cylinder (30).
The support panel 10 is configured in the form of a square plate, the lower side is provided with a rotary shaft 11 rotatably coupled to the upper surface of the support frame 2 in the upper surface of the support frame (2) Rotating in the lateral direction to the rotation shaft 11, the rotation drive mechanism 12 is connected.
The rotation drive mechanism 12 uses a hydraulic motor, and is connected to the circumferential surface of the rotation shaft 11 by a gear so as to rotate the support panel 10 laterally according to the driving thereof.
The rotating panel 20 is configured in the form of a square plate, as shown in Figures 2 and 4, the lower end can be rotated in the front and rear direction to the rotating bracket 13 provided in front of the support panel 10. To be combined.
At this time, the rotation panel 20 is configured to be rotated forward by the hydraulic cylinder 30 in the installation state installed to stand vertically on the upper portion of the support panel 10.
In addition, as shown in FIGS. 4 and 5, a plurality of coupling holes 21 are formed in the pivoting panel 20 so as to correspond to the through holes 5b formed in the flange portion 5a of the blade 5. It is formed to penetrate the surface, it is possible to fix the proximal end of the blade (5) to the rear side of the rotation panel 20 by using the bolt 22 through the through hole (5b) and the coupling hole (21). It is configured to be.
The hydraulic cylinder 30 is stretched by the pressure of the oil supplied to the inside, it consists of a pair of left and right, both ends of the hinge bracket 14 is provided on both sides of the support panel 10 and the rotation panel 20. 23 is hinged to.
Therefore, as shown in FIGS. 4 and 6, when the hydraulic cylinder 30 is contracted, the pivot panel 20 stands vertically, and when the hydraulic cylinder 30 is extended, the pivot panel 20 is moved forward. It is rotated inclined so that the tip portion of the blade 5 is lifted upward.
In addition, an auxiliary fixing means 40 is further provided on the rear upper surface of the support frame 2 to support and fix the middle portion of the blade 5. The auxiliary fixing means 40 is configured by assembling a high strength metal beam, by the vibration generated when the trailer moves by supporting the intermediate portion of the blade 5 in the state where the tip of the blade 5 is lowered The blade 5 is prevented from moving.
The blade transport trailer for wind turbines configured as described above is configured by rotating the hydraulic cylinder 30 to rotate the pivoting panel 20, as shown in FIG. 6, and having a proximal end fixed to the pivoting panel 20. ) Can be lifted upward, and the support panel 10 is rotated laterally using the rotation drive mechanism 12 in a state where the tip of the blade 5 is lifted upward. Can rotate sideways.
Therefore, when driving on a straight road, the blade 5 is lowered so that the blade 5 is fixed to the auxiliary fixing means 40, and the blade 5 is moved upward when moving along a corner or a mountain road. The tip of the blade 5 extending obliquely to the rear side of the trailer may not interfere with the surrounding trees or structures.
In addition, when the height of the surrounding trees or structures or the width of the road is very narrow so that the blade 5 may interfere with the surrounding trees or structures even when the front end of the blade 5 is lifted upward, FIG. As shown, the support panel 10 can be rotated laterally using the rotation driving mechanism 12 so that the blade 5 does not interfere with the surrounding trees or structures.
Therefore, when the blade 5 is transported using a trailer, the blade 5 can be effectively prevented from being damaged by interference with surrounding trees or structures, and the blade 5 can be smoothly transported. There is an advantage.
In addition, a plurality of coupling holes 21 corresponding to the through holes 5b formed in the flange portion 5a of the blade 5 are formed in the rotation panel 20, and the through holes 5b and the coupling holes are formed. The bolt 22 penetrating through the 21 has the advantage that the base end of the blade (5) can be firmly fixed to the rear side of the rotation panel (20).
In addition, the rear frame of the support frame 2 is further provided with an auxiliary fixing means 40 for supporting and fixing the intermediate portion of the blade 5 to the blade 5 in the lowered state of the blade 5 Since the intermediate part is supported and fixed by the auxiliary fixing means 40, the vibration generated when the trailer moves is transmitted to the blade 5 and the fixing means 4, and thus to the blade 5 and the fixing means 4 There is an advantage that can be prevented from being subjected to excessive shock.
It is to be understood that the foregoing is merely illustrative of one preferred embodiment of the present invention and that modifications and variations may be made thereto without departing from the spirit of the invention.
