[0009] Hollow rectangular tubes are provided at the left and right ends of the base, and the forklift forks can extend into the rectangular tubes from the front and rear directions.
[0010] Multiple rectangular cut plates are arranged on the front side of the upright. The rectangular cut plates on the two uprights are arranged symmetrically and are inclined relative to each other so that the arc-shaped cross section of the wind vane with the opening facing forward is tangent to the corresponding rectangular cut plate.
[0011] Furthermore, the base includes two rectangular tubes arranged in parallel, a fixing rod, and a middle rod perpendicular to the fixing rod;
[0012] The two ends of the fixing rod are perpendicular to the middle positions of opposite sides of the rectangular tube;
[0013] The intermediate rod is perpendicular to the middle position of the front side of the fixed rod.
[0014] Furthermore, the orientation of the rectangular cutting plate is adjustable, two flat plates are fixed on the rectangular cutting plate, and two mounting plates are fixed on the front side of the upright. The flat plates and mounting plates are fastened with bolts and nuts after the positions are adjusted.
[0015] Furthermore, multiple climbing handles are arrayed on the rear side of the diagonal bar.
[0016] Furthermore, a rubber pad is laid on the top surface of the base.
[0017] Furthermore, the number of rectangular cutting plates is four, with two rectangular cutting plates fixed on each upright.
[0018] Furthermore, it also includes two lifting rings, which are fixed to the upper end of the diagonal rod.
[0019] In the above technical solution, the present invention has the following beneficial effects:
[0020] In use, place the bottom surface of the wind turbine tower blades upright on the top surface of the base, with the curved surface of the wind turbine tower blades facing backward and the opening facing forward, allowing multiple rectangular cut plates to surround one side of the curved surface. Then, use ropes to tie the wind turbine blades and the transfer fixture together, and finally, use a forklift to move them together. The transfer fixture takes into full account the shape of the wind turbine tower blades; the outer surface of the curved surface in the vertical direction can be tied to the transfer fixture, facilitating binding.

[0029] like Figure 1-3 The illustrated fan blade transfer fixture includes a base 1, two square uprights 4, a reinforcing rod 3, two diagonal rods 2, and multiple rectangular cutting plates 5.
[0030] Base 1 is the foundation for the transfer tooling to install various parts, and the bottom surfaces of the wind vanes and wind turbine tower plates are placed on the base.
[0031] Two upright poles 4 are erected and vertically fixed to the left and right ends of the base 1; the two ends of the reinforcing rod 3 are vertically fixed to the upper ends of the two upright poles 4; the two upright poles 4 and the reinforcing rod 3 are fixed in a gate-shaped configuration in the middle area of the base. The reinforcing rod 3 prevents the wind vanes from moving.
[0032] The two ends of the diagonal brace are fixedly connected to the upper end of the upright 4 and the rear end of the base 1, respectively; the diagonal brace, the base and the upright form a right triangle.
[0033] Hollow rectangular tubes 61 are provided at the left and right ends of the base 1, and the forklift forks can extend into the rectangular tubes 61 from the front and rear directions; the size of the rectangular tubes of the base 1 matches the forks, and the base increases the forklift's mobility.
[0034] Preferably, the base 1 includes two rectangular tubes 61 arranged in parallel, a fixed rod, and a middle rod 62 perpendicular to the fixed rod.
[0035] The two ends of the fixing rod are perpendicular to the middle of opposite sides of the rectangular tube 61, forming an I-shape. The middle rod 62 is perpendicular to the middle of the front side of the fixing rod. The middle rod 62 provides support for the middle of the bottom surface of the fan blade. This base has more openings, providing more space for the rope to pass through.
[0036] Multiple rectangular cut plates 5 are installed on the front side of the upright 4. The rectangular cut plates 5 on the two uprights 4 are arranged symmetrically. The rectangular cut plates 5 on the two uprights 4 are inclined relative to each other so that the arc-shaped cross section of the air vane with the opening facing forward is tangent to the corresponding rectangular cut plate 5. One side of the arc-shaped surface of the air vane is attached to the rectangular cut plate 5. From back to front, two rectangular cut plates 5 at the same height are arranged in a V-shape facing each other.
[0037] Preferably, there are four rectangular cutting plates 5, with two rectangular cutting plates 5 fixed on each upright 4. This provides support for the curved side of the fan blade in all four directions: top, bottom, left, and right.
[0038] The rectangular cut plate 5 can be fixed to the front side of the pole 4, or the following connection scheme can be used to adapt to wind blades with different curvatures.
[0039] Preferably, the orientation of the rectangular cutting plate 5 is adjustable. Two flat plates 51 are fixed on the rectangular cutting plate 5, arranged horizontally and vertically, located on the rear side of the rectangular cutting plate. Two mounting plates are fixed on the front side of the upright 4, and the two mounting plates can be attached to the two flat plates 51 respectively. The flat plates 51 and the mounting plates are fastened with vertical bolts and nuts after the positions are adjusted.
[0040] Preferably, multiple climbing handles 7 are arrayed on the rear side of the diagonal bar 5. A person can climb to the top of the transfer device to operate the rope.
[0041] Preferably, a rubber pad 8 is laid on the top surface of the base 1. The rubber pad serves to protect the fan blades.
[0042] Preferably, it also includes two lifting rings 9, which are fixed to the upper end of the diagonal rod 2. This facilitates the use of lifting fixtures to lift and transport the fixtures, adding another method of transportation.
[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
