[0002] Wind turbine blades are the core components of wind turbine units that convert natural wind energy into electrical energy. They are also the main basis for measuring the design and technical level of wind turbine units. After the wind turbine blades are manufactured, they need to be transferred to the location where they need to be installed, which requires transportation.

[0003] Chinese Patent Publication No. CN215398802U discloses a wind turbine blade transport device, belonging to the technical field of transport devices. It includes a load-bearing base plate and a placement frame. Two forklift holes are provided on the load-bearing base plate. A jack is detachably connected to the upper end of the load-bearing base plate. The placement frame is movably connected to the upper end of the jack via a compression spring. Two sets of jacks and compression springs are provided and symmetrically distributed along the central axis of the load-bearing base plate. A rubber pad is detachably connected inside the placement frame, and a fixing device is detachably connected to the placement frame. This utility model utilizes a U-shaped placement frame to fix the placement position of the wind turbine blade, ensuring the safety of the wind turbine blade during transportation. The rubber pad inside the placement frame reduces friction between the wind turbine blade and the frame, reducing wear on the wind turbine blade surface. The jack can lift one side of the placement frame, facilitating the loading and unloading of the wind turbine blade and increasing the flexibility of the device.

[0004] The jacks in the wind turbine blade transport device described above can lift one side of the placement frame, facilitating the loading and unloading of wind turbine blades. However, the device lacks a limit adjustment structure. Limiting the wind turbine blades using a U-shaped placement frame combined with binding ropes is cumbersome during loading and unloading. Therefore, we propose a wind turbine blade transport device with a limit adjustment structure. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the extension rod can be stretched with the limiting rod, so that the length of the limiting structure can be adjusted according to the size of the wind turbine blade.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown;

[0023] A wind turbine blade transport device with a limit adjustment structure includes a transport box 1. Positioning ends 13 are fixed on both sides of the upper part of the transport box 1. A drive motor 6 is bolted to one end of the positioning end 13. A limit rod 3 is fixed to the output end of the drive motor 6. An extension rod 4 is movably connected to one side of the limit rod 3. A fastening bolt 5 is installed at one end of the limit rod 3. A drive switch 7 is installed on the outside of the positioning end 13. A support plate 2 is installed on the inside of the transport box 1. Nut blocks 10 are fixed on both sides of the support plate 2. A linkage lifting plate 11 is fixed on the outside of the nut blocks 10.

[0024] In this implementation scheme: the extension rod 4 can be stretched with the limiting rod 3, so the length of the limiting structure can be adjusted according to the size of the wind turbine blade. The limiting rod 3 presses against the blade to limit the wind turbine blade during transportation. The drive motor 6 can drive the limiting rod 3 to rotate and open, so as to facilitate the upward movement of the support plate 2 and the blade, and facilitate the unloading of the blade.

[0025] Furthermore:

[0026] In an optional embodiment, the extension rod 4 and the limiting rod 3 form a tension structure, and the extension rod 4 is fixed relative to the limiting rod 3 by fastening bolts 5.

[0027] In this implementation scheme: the extension rod 4 can be stretched with the limiting rod 3, so that the length of the limiting structure can be adjusted according to the size of the wind turbine blade. The limiting rod 3 is used to press against the blade to limit the wind turbine blade during transportation.

[0028] Furthermore:

[0029] In an optional embodiment, a transmission screw 9 is inserted inside the nut block 10, and a transmission motor 8 is connected to one end of the transmission screw 9. The transmission motor 8 and the transmission screw 9 form a rotating structure, and the transmission screw 9 is threadedly connected to the nut block 10.

[0030] In this implementation scheme: the transmission motor 8 can drive the transmission screw 9 to rotate, and the rotating transmission screw 9 can vertically transmit the nut block 10 and the support plate 2, thereby facilitating the lifting and lowering of the blades.

[0031] Furthermore:

[0032] In an optional embodiment, a conductive patch 12 is adhered to the inner side of the linkage lifting plate 11, and the linkage lifting plate 11 corresponds to the position of the drive switch 7.

[0033] In this implementation scheme: the linkage lifting plate 11 can rise and fall together with the support plate 2. After the linkage lifting plate 11 moves up, the conductive patch 12 can come into contact with the drive switch 7, which facilitates the power supply to the drive switch 7.

[0034] Furthermore:

[0035] In an optional embodiment, the drive switch 7 is electrically connected to the drive motor 6 via a wire, and the drive motor 6 and the limit rod 3 form a rotating structure.

[0036] In this implementation scheme: after the drive switch 7 is powered on, the drive motor 6 can be started. The drive motor 6 can drive the limit rod 3 to rotate and open, thereby facilitating the upward movement of the support plate 2 and the blades, and making it convenient to unload the blades.

[0037] Working principle: First, the wind turbine blade to be transported is placed on the support plate 2. The length of the limiting structure is adjusted according to the size of the wind turbine blade. The extension rod 4 and the limiting rod 3 are stretched to a suitable position, and then fixed with fastening bolts 5. The end of the extension rod 4 is pressed against the blade, which can limit the wind turbine blade during transportation. Next, after the blade is transported to the designated location, the two conveyor motors 8 are started at the same time. The conveyor motors 8 are mature products in the existing technology. The conveyor motors 8 drive the conveyor screw 9 to rotate. The two screws can be driven by independent motors. Position synchronization is achieved through closed-loop control such as encoder feedback. The rotating conveyor screw 9 vertically conveys the nut block 10, the support plate 2, and the linkage lifting plate 11 upward, thereby moving the blade upward. After moving upward a certain distance, the conductive patch 12 on the inner side of the linkage lifting plate 11 and the drive switch... When phase 7 is in contact, the drive switch 7 is energized. Once the drive switch 7 is energized, the drive motor 6 is started. The drive motor 6 drives the limit rod 3 to rotate and open. At the same time, the support plate 2 and the blade continue to move upward to the top of the transport box 1, which facilitates the unloading of the blade without having to remove the blade from the bottom of the box. The drive motor 6 is equipped with two switches, which control the start and stop of the motor through independent contacts and use a contactor or PLC to achieve electrical interlocking to prevent the two switches from triggering at the same time and causing a short circuit. One is the drive switch 7, which is an automatic switch, and the other is a manual switch. The automatic switch can control the drive motor 6 to rotate forward, and the manual switch can control the drive motor 6 to rotate in reverse. After the blade is unloaded, the reverse transmission screw 9 drives the nut block 10 and the linkage lifting plate 11 back to their original positions, and the drive switch 7 is de-energized. At this time, the manual switch can be used to control the drive motor 6 to rotate in reverse, which can drive the limit rod 3 back to its original position.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
