Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
As shown in fig. 1 to 9, a supporting structure of a blade of a wind turbine includes a front supporting frame and a rear supporting frame, wherein a front end of the blade is placed on the front supporting frame, and a rear end of the blade is placed on the rear supporting frame.
The front support frame comprises a rectangular bottom frame 9, two corners at the front end of the bottom frame 9 are respectively and fixedly connected with stand columns 3, the upper ends of the two stand columns 3 are connected through a cross beam 5, two corners at the rear end of the bottom frame 9 are respectively and fixedly connected with support arms 7, and the upper ends of the support arms 7 are fixedly connected with the upper ends of the stand columns 3. A fixing plate 8 is fixedly connected between the opposite sides of the two upright posts 3 and the underframe 9 respectively, and the fixing plate 8 is provided with an ear plate 2. An arc-shaped supporting piece 4 is arranged behind the fixing plate 8, and the lower end of the arc-shaped supporting piece 4 is fixed on the bottom frame 9. The arc-shaped supporting piece 4 comprises an arc-shaped steel plate, the lower end of the arc-shaped steel plate is fixedly connected with a plurality of supporting steel plates 14, and the lower ends of the supporting steel plates 14 are fixedly connected to the bottom frame 9 of the front supporting frame. The radius of the circular arc steel plate is slightly larger than the diameter of the blade of the wind driven generator at the installation position. The lug plates 2 and the cross beam 5 are respectively provided with a plurality of positioning holes 6, the positioning holes 6 are positioned on the same circumference, and the circumference is matched with the circumference formed by the blade mounting holes of the wind driven generator. In the process of placing the blade on the front support frame, the positioning hole 6 and the mounting hole of the blade are fixed through the pin shaft, and then the blade is firmly fixed, so that the relative movement between the blade and the front support frame is reduced.
The upper end of the upright post 3 of the front support frame is also provided with a hoisting area 1, and the hoisting area 1 is positioned on two side surfaces facing the outer side of the upright post 3. The hoisting area 1 comprises two D-shaped rings 10, the D-shaped rings 10 are respectively arranged in a fixing pipe 12 in a penetrating mode, the fixing pipe 12 is fixed on a connecting plate 11, and the connecting plate 11 is fixed on the side face of the upper end of the upright post 3. The front support frame can be conveniently moved on or off a truck through the D-shaped ring 10, and the front support frame can be conveniently used.
The rear support frame comprises a first rear support frame and a second rear support frame, and the second rear support frame is positioned behind the first rear support frame. First back support frame includes chassis 9, is provided with stand 3 on four angles of chassis 9 respectively, through 15 fixed connection of steel pipe between two front and back stands 3, fixedly connected with steel template 13 between the front end stand 3 and between the rear end stand 3. Since the rear end of the blade is gradually narrowed, the height of the support frame for supporting the rear end of the blade needs to be increased.
