[0022] Reference Figure 1 and Figure 2 This invention relates to a wind turbine blade feeding and towing traction device in some embodiments of the present invention. It includes a support base 1 and a pair of wind turbine blade traction mechanisms 2 separately installed on both sides of the support base 1. Each wind turbine blade traction mechanism 2 includes a mounting base 21, a traction driver 22, a winch 23, a binding assembly, and a limiting and guiding mechanism 25. The mounting base 21 is mounted on the support base 1, the traction driver 22 is mounted on the mounting base 21, the output end of the traction driver 22 is connected to the winch 23, the binding assembly is connected to the winch 23 and used to bind and lock the wind turbine blade, and the limiting and guiding mechanism 25 is connected to the mounting base 21 and used to guide and limit the binding assembly.

[0023] Understandably, this wind turbine blade feeding and towing device, by setting a pair of wind turbine blade traction mechanisms 2 on both sides of the support base 1, allows for the synchronous transport of wind turbine blades. Simultaneously, the wind turbine blades are secured and locked by a binding assembly. The traction driver 22 drives the binding assembly to move, thereby towing the wind turbine blades. Furthermore, a limiting and guiding mechanism 25 guides and limits the binding assembly. This wind turbine blade feeding and towing device has a reasonable structure, enabling stable traction of wind turbine blades, convenient operation, and secure fixing of the wind turbine blades, effectively ensuring the safety of the wind turbine blades during the towing process.

[0024] The binding assembly includes binding ropes, binding straps, and universal joints. The binding ropes are used to bind the wind turbine blades to the outside. The binding straps are connected to the binding ropes via universal joints, and the binding straps are connected to the winch 23. The binding ropes can be steel wire ropes, made of multiple strands of twisted steel wire, which are high-strength and wear-resistant. The binding straps are mainly woven or sewn from high-strength synthetic fibers such as polyester and nylon. In this embodiment, the binding straps are loop straps for easy hooking. The binding ropes can tightly fit the outside of the wind turbine blades for a secure binding. The universal joints allow the binding straps to adapt to different angle changes of the blades during traction, avoiding unnecessary tension or damage to the blades due to a fixed angle. This ensures that the binding straps can self-adapt to balance during tightening, preventing them from spinning when wound on the winch 23, and also improving traction flexibility. In use, the binding ropes are tightly bound to the outside of the wind turbine blades, and the binding straps connected by the universal joints can flexibly adapt to changes in the blade angle.

[0025] like Figure 2 As shown, the traction drive 22 includes a servo motor 221 and a worm gear reducer 222 connected to the servo motor 221. The output end of the worm gear reducer 222 is connected to the winch 23. The servo motor 221 features high control precision and fast response speed, enabling precise control of the rotation speed and amount of rotation of the winch 23, thereby achieving precise control of the wind turbine blade feed and towing speed. The worm gear reducer 222 provides a large reduction ratio and torque to meet the traction requirements of heavier wind turbine blades. It also has a self-locking function to prevent the winch 23 from reversing during traction, ensuring the stability and safety of the traction. In essence, the servo motor 221 drives the worm gear reducer 222, which in turn drives the winch 23 to rotate, thereby driving the binding assembly and towing the wind turbine blade.

[0026] The wind turbine blade feeding and towing traction device also includes a bearing housing 3 mounted on the mounting base 21, with the output end of the worm gear reducer 222 passing through the bearing housing 3. The bearing housing 3 provides support and positioning for the output end of the worm gear reducer 222, reducing the shaking of the output end during rotation, improving the stability of the entire traction drive 22, and extending the service life of the equipment.

[0027] The worm gear reducer 222 is equipped with a torque sensor, which can monitor the torque output of the worm gear reducer 222 in real time. When the torque exceeds the preset value during traction, it can send a signal in time so that the operator can take corresponding measures to prevent damage to the wind turbine blades or equipment components due to excessive traction force, thus playing an effective protective role.

[0028] The worm gear reducer 222 is equipped with a displacement sensor, which can monitor the rotational displacement of the winch 23 in real time, and then calculate the traction length of the binding assembly. This allows operators to accurately control the feed and drag distance of the wind turbine blades, achieve precise control, and improve the accuracy and efficiency of operation.

[0029] Furthermore, the limiting and guiding mechanism 25 includes a pair of limiting components, which are separately installed on both sides of the mounting base 21. Each limiting component includes a connecting seat 251 connected to the mounting base 21 and a guide shaft 252 rotatably connected to the connecting seat 251. A passage space for the binding strap to pass through is provided between the guide shaft 252 and the connecting seat 251. Understandably, by providing limiting components on both sides of the mounting base 21, the binding strap can be limited and guided from both sides of the mounting base 21, preventing the binding strap from deviating during traction and ensuring that the binding strap always moves along a preset trajectory, thus improving traction stability. The binding strap passes through the passage space. During traction, the guide shaft 252 rotates with the movement of the binding strap, converting the sliding friction between the binding strap and the limiting components into rolling friction, reducing wear on the binding strap, and also providing good guidance to ensure smooth movement of the binding strap.

[0030] The support base 1, mounting base 21, and connecting base 251 are all equipped with anti-rust coatings. The anti-rust coating can effectively isolate these components from corrosive media such as air and moisture, prevent them from rusting, and extend the service life of the equipment. It is especially suitable for harsh outdoor environments such as damp places where wind power equipment may be located.

[0031] The support frame 1, mounting base 21, and connecting base 251 are all made of stainless steel or aluminum alloy. Stainless steel has good corrosion resistance and strength, while aluminum alloy is lightweight, high-strength, and corrosion-resistant. Using these materials to make the support frame 1, mounting base 21, and connecting base 251 can ensure the structural strength of the equipment, further improve its corrosion resistance and service life, and the aluminum alloy material can also reduce the overall weight of the equipment, making it easier to transport and install.

[0032] The working principle of this wind turbine blade feeding and towing device is as follows: When feeding and towing the wind turbine blade, the blade is first securely bound with a binding rope in the binding assembly. The binding strap is connected to the binding rope via a universal joint and wound around the winch 23. The servo motor 221 is started, and it drives the winch 23 to rotate via a worm gear reducer 222. The winch 23 then winds up the binding strap, thereby towing the wind turbine blade. During the traction process, the guide shaft 252 in the limiting and guiding mechanism 25 guides and limits the binding strap, preventing it from deviating. Torque and displacement sensors monitor the traction force and displacement respectively, ensuring a safe and accurate traction process.

[0033] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
