[0037] Combine the following Figure 1-Figure 6 The wind turbine blade transfer device of the present invention is described.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a wind turbine blade transfer device includes a transport vehicle body 100 , a first hydraulic cylinder 200 , a positioning frame 300 , a support plate 400 , an adjustment assembly 500 and a second hydraulic cylinder 600 .

[0039] The transport vehicle body 100 has a support base 110 .

[0040] The first hydraulic cylinder 200 is installed on the support base 110 .

[0041] The positioning frame 300 is hinged at the output end of the first hydraulic cylinder 200 , the positioning frame 300 is rotatably connected to the support seat 110 , and the positioning frame 300 has a bottom plate 310 .

[0042] The support plate 400 is rotatably connected to the positioning frame 300 , and the support plate 400 has a plurality of positioning holes 410 .

[0043] The adjusting assembly 500 is installed on the positioning frame 300 , and the adjusting assembly 500 is used to adjust the position of the positioning hole 410 .

[0044] The second hydraulic cylinder 600 is installed on the positioning frame 300 , and the output end of the second hydraulic cylinder 600 has a clamping plate 610 .

[0045] When the bolt at the end of the wind turbine blade is inserted into the corresponding positioning hole 410, the bottom plate 310 abuts against the wind turbine blade, and the clamping plate 610 has a slot 620 matching the end of the wind turbine blade, see Figure 4 .

[0046] When the wind turbine blade transfer device is in use, the bolt at the end of the wind turbine blade is inserted into the corresponding positioning hole 410, so that the bottom plate 310 abuts against the wind turbine blade, and the second hydraulic cylinder 600 is started to make the end of the wind turbine blade just snap into the slot 620. When turning is required during transportation, the elevation angle of the wind turbine blade can be adjusted according to the road conditions by controlling the first hydraulic cylinder 200, thereby reducing the turning radius. At the same time, it is convenient to reduce the damage to the surface of the wind turbine blade caused by the surrounding tree trunks when turning. The operation is simple and easy to use.

[0047] In this embodiment, when the first hydraulic cylinder 200 drives the positioning frame 300 to rotate, the angle between the supporting plate 400 and the supporting seat 110 ranges from 90 degrees to 150 degrees.

[0048] When the angle between the support plate 400 and the support seat 110 is 90 degrees, the wind turbine blades are parallel to the support seat 110, which makes it convenient to install the wind turbine blades on the support plate 400. At this time, the turning radius required by the wind turbine blades is longer, but the force acting on the support plate 400 is smaller, and the weight of the wind turbine blades is dispersed on the base plate 310, which is suitable for flat and straight roads. When the angle between the support plate 400 and the support seat 110 is 150 degrees, the elevation angle of the wind turbine blades is 60 degrees. At this time, the turning radius required by the wind turbine blades is smaller, but the weight of the wind turbine blades is concentrated on the support plate 400, and the strength requirements of the support plate 400 are higher, which is suitable for mountain roads that require turning.

[0049] Specifically, the adjustment assembly 500 includes a second motor 510, a first gear 520 and a gear ring 530. The second motor 510 is installed on the positioning frame 300, the first gear 520 is fixed at the output end of the second motor 510, and the gear ring 530 is fixed on the outer wall of the support plate 400. The first gear 520 and the gear ring 530 are meshed with each other.

[0050] During adjustment, the second motor 510 is started to drive the first gear 520 to rotate, the first gear 520 drives the gear ring 530 to rotate, and the gear ring 530 drives the support plate 400 to rotate, so as to facilitate the adjustment of the position of the positioning hole 410 according to the bolt position at the end of the wind turbine blade.

[0051] like Figure 2 As shown, in one embodiment, a first motor 120 is installed on the transport vehicle body 100 , and an output end of the first motor 120 is fixedly connected to the support base 110 .

[0052] The first motor 120 is started to drive the support base 110 to rotate, and the support base 110 drives the positioning frame 300 to rotate, so that when installing the wind turbine blades, the support plate 400 is located at one end close to the head of the transport body 100. During transportation, the support plate 400 is located at one end close to the rear of the transport body 100, further reducing the turning radius during transportation.

[0053] In this embodiment, see Figure 5 A guide rail 700 is fixedly connected to the support seat 110, and a third motor 710 is installed on the support seat 110. A screw rod 720 is fixedly connected to the output end of the third motor 710. A slider 730 is threadedly connected to the outer wall of the screw rod 720. The slider 730 is slidably connected to the guide rail 700. A lifting platform 740 is installed on the surface of the slider 730. A support frame 750 is fixedly connected to the free end of the lifting platform 740. A clamping assembly 760 is installed on the support frame 750. The clamping assembly 760 is used to clamp the wind turbine blades.

[0054] When adjusting the elevation angle of the wind turbine blade, the lifting platform 740 is synchronously controlled so that the clamping assembly 760 always clamps and fixes the wind turbine blade. By starting the third motor 710 to drive the screw rod 720 to rotate, the screw rod 720 drives the slider 730 to move on the guide rail 700, so as to facilitate the adjustment of the support point of the wind turbine blade by the clamping assembly 760 according to the elevation angle of the wind turbine blade, so as to facilitate the lifting platform 740 to share the force of the wind turbine blade on the support plate 400, thereby increasing the service life of the support plate 400 and, at the same time, improving the stability and preventing the wind turbine blade from shaking during transportation, thereby reducing the driving difficulty of the transport personnel and improving the safety of the transport personnel.

[0055] In this embodiment, the clamping assembly 760 includes a power piece 761, a first rotating shaft 765 and a mechanical gripper 768. The first rotating shaft 765 is symmetrically rotatably connected to the support frame 750. The power piece 761 is used to drive the two first rotating shafts 765 to rotate towards each other. The mechanical gripper 768 corresponds to the first rotating shaft 765 one by one, and the mechanical gripper 768 is fixed on the corresponding first rotating shaft 765.

[0056] For details, see Figure 5 and Figure 6 The power member 761 includes a fourth motor 762, a second gear 763 and a third gear 764. The fourth motor 762 is installed on the support frame 750. The output end of the fourth motor 762 is fixedly connected to the second rotating shaft 766. The second gear 763 is fixed to the outer wall of the second rotating shaft 766. One of the first rotating shafts 765 is fixed to the third gear 764. The second gear 763 and the third gear 764 are meshed with each other. A chain 767 is transmission-connected between the other first rotating shaft 765 and the second rotating shaft 766.

[0057] When the clamping assembly 760 is in use, the fourth motor 762 is started to drive the second rotating shaft 766 to rotate, the second rotating shaft 766 drives the second gear 763 to rotate, and the second gear 763 drives the third gear 764 to rotate. At the same time, under the transmission action of the chain 767, the two first rotating shafts 765 rotate towards each other, thereby facilitating the mechanical gripper 768 to clamp and fix the wind turbine blades.

[0058] It should be noted that an auxiliary belt 769 is fixedly connected between adjacent mechanical grippers 768, so that when the pitch angle of the wind turbine blade is adjusted, the auxiliary belt 769 can always support the wind turbine blade, thereby improving the stability of the wind turbine blade during transportation.

[0059] like Figure 1 and Figure 2 As shown, in one embodiment, a monitoring station 130 is provided on one end of the support seat 110 away from the support plate 400, so as to facilitate the cooperation between the monitoring personnel and the driver of the transport vehicle 100, thereby improving the safety performance during transportation and ensuring the transfer quality of the wind turbine blades.

[0060] In this embodiment, a controller 140 is provided on the monitoring station 130, and the controller 140 is used to control the first motor 120, the first hydraulic cylinder 200, the second motor 510, the second hydraulic cylinder 600, the third motor 710, the lifting platform 740 and the fourth motor 762, so as to facilitate the monitoring personnel at the monitoring station 130 to control the angle and position of the wind turbine blades according to the road conditions.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
