Description

Technical Field

[0001] This utility model relates to the field of wind power equipment installation technology, specifically a high-altitude wind turbine single blade aerial precision positioning auxiliary device. Background Technology

[0002] When constructing wind farms in mountainous areas, the installation of wind turbine blades is one of the most challenging aspects of construction due to steep terrain, limited transportation, and confined working space. Single-blade installation, in particular, is widely used due to its adaptability and high safety.

[0003] Existing auxiliary devices for wind turbine single-blade installation are mostly simple traction ropes or guide bracket structures, lacking effective support structures for blade attitude stability and precise positioning in complex high-altitude environments. These devices often cannot achieve blade angle adjustment and position fine-tuning in the air, resulting in repeated adjustments during hoisting, which is time-consuming, seriously affecting construction efficiency, and increasing the operational difficulty and safety risks for workers. At the same time, most existing devices do not have the function of rapid installation and disassembly, making it difficult to meet the actual needs of frequent site relocation and limited working time in high-altitude areas. Utility Model Content

[0004] The purpose of this utility model is to provide an aerial precision positioning auxiliary device for single blades of high-altitude wind turbines, in order to solve the problems mentioned in the background art, such as difficulty in attitude control, insufficient positioning accuracy, and inability to achieve angle adjustment and position fine-tuning during the hoisting of single blades under complex terrain conditions in high-altitude areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aerial precision positioning auxiliary device for a single blade of high-altitude wind turbine, comprising a main support frame, a clamp assembly fixedly sleeved on the outside of the main tower rod on one side of the main support frame, a reinforcing frame fixed at the bottom of the main support frame, a rotating base driven by a rotary motor at the upper end of the reinforcing frame, vertically distributed lifting cylinders fixed at the top of the rotating base, a lifting bearing plate fixed at the output end of the lifting cylinders, and a dynamic auxiliary support component with multi-directional adjustment function at the top of the lifting bearing plate.

[0010] Preferably, a number of horizontally distributed support beams are welded and fixed to the bottom of one side of the clamp assembly, and the support beams are evenly distributed in a fan shape at the bottom of the main support frame.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This high-altitude wind turbine single-blade aerial precision positioning auxiliary device achieves precise positioning and angle adjustment of the blade in the air, improving hoisting stability and operational safety. It also features rapid installation and disassembly, significantly improving construction efficiency and adapting to the needs of complex mountainous environments.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a high-altitude wind turbine single-blade aerial precision positioning auxiliary device, including a main support frame 1, which is an L-shaped structure. A clamp assembly 2, which is fixedly fitted onto the outside of the tower main rod, is welded and fixed to one side of the main support frame 1. The clamp assembly 2 consists of two semi-circular arc-shaped clamps, which are fastened together by matching diagonal bolts, allowing for secure fitting and locking onto the outside of the tower main rod, thus enabling rapid installation and disassembly between the main support frame 1 and the tower. A reinforcing frame 3, which is a U-shaped structure, is fixed to the bottom of the main support frame 1. A rotating base 5, driven by a rotary motor, is located at the upper end of the reinforcing frame 3. The rotating base 5 is a circular structure, with its center connected to the reinforcing frame 3 via a bearing. A vertically distributed lifting cylinder 6 is bolted to the top of the base 5. A lifting bearing plate 7 is fixed to the output end of the lifting cylinder 6. The top of the lifting bearing plate 7 is equipped with a dynamic auxiliary support component 8 with multi-directional adjustment function. This structure uses a clamp assembly 2 to stably fix the main support frame 1 at a suitable height position on the main tower, ensuring the foundation stability of the entire device during high-altitude operations. The reinforcing frame 3 provides solid support for the overall structure, enhancing its load-bearing capacity and wind resistance. A rotary motor drives the rotating base 5 to achieve flexible horizontal steering adjustment, which, in conjunction with the lifting cylinder 6, adjusts the vertical height of the lifting bearing plate 7, thereby driving the dynamic auxiliary support component 8 on top to the required working position. The dynamic auxiliary support component 8 also has a multi-directional adjustment function. During blade hoisting, the spatial attitude of the support points can be finely adjusted in real time, effectively assisting the blade in achieving aerial angle changes and precise positioning. Therefore, through the coordinated work of the above structures, the controllability and stability of the hoisting process are significantly improved, solving the problems of difficult blade attitude control, insufficient positioning accuracy, and repeated adjustments affecting efficiency caused by the lack of effective support structures in existing technologies. It is particularly suitable for wind power construction needs in complex environments in high-altitude areas. The lifting bearing plate 7 has a recessed groove inside, and the recessed groove inside the lifting bearing plate 7 is connected to a rotating swing plate 9 through a swing cylinder. One end of the rotating swing plate 9 is connected to the lifting bearing plate 7 through a hinge. In this structure, the swing cylinder inside the recessed groove of the lifting bearing plate 7 can be a standard industrial double-acting swing cylinder, for example... If a pneumatic actuator of similar performance, such as the DRQ series manufactured by FESTO, is used, one end of the swing cylinder is hinged to the fixed support of the recessed groove inside the lifting support plate 7 via a pin, and the other end is connected to the middle of the bottom of the rotating swing plate 9 via an output shaft. This allows the swing cylinder to drive the rotating swing plate 9 to reciprocate around the hinge point between it and the lifting support plate 7, effectively realizing precise swing control of the rotating swing plate 9 within a certain angle range, providing a reliable power input and angle adjustment basis for subsequent support and positioning actions. A roller bracket 10 is welded and fixed to the outside of the rotating swing plate 9. The inside of the roller bracket 10 is driven by a servo motor to a rotating shaft 11. Both ends of the rotating shaft 11 are connected to the inner walls of both sides of the roller bracket 10 via a rotating shaft.Furthermore, the servo motor is bolted to one side of the outside of the roller support 10, and its output shaft is connected to the rotating shaft at one end of the rotating shaft 11. A threaded connecting column 13 is welded and fixed to the middle of the outer side of the rotating shaft 11, and a threaded connecting ring 14 that matches the structure of the threaded connecting column 13 is welded and fixed to the bottom of the dynamic auxiliary support 8. When the servo motor outside the roller support 10 drives the rotating shaft 11 to rotate, this structure can drive the dynamic auxiliary support 8 to make precise position adjustments, thereby realizing multi-directional and multi-angle fine adjustment of the wind turbine blades, ensuring their precise positioning and attitude stability in the air. At the same time, the connection method of the threaded connecting column 13 and the threaded connecting ring 14 not only ensures a firm connection between the two, but also allows for quick disassembly and assembly of the dynamic auxiliary support 8 according to actual needs, improving the flexibility and adaptability of the equipment. A "C"-shaped elastic support 12 is symmetrically connected between the lifting bearing plate 7 and the rotating base 5. The contact surfaces of the elastic support 12 with the lifting bearing plate 7 and the rotating base 5 are all fixed by welding. Located on both sides of the lifting cylinder 6 with corresponding opening directions, this structure allows the connected elastic support 12 to move synchronously when the lifting bearing plate 7 is vertically raised and lowered under the action of the lifting cylinder 6. This utilizes the elastic deformation capability of the elastic support 12, providing additional buffering while ensuring structural rigidity, effectively absorbing and mitigating vibrations and impacts that may occur during lifting, thus improving the stability and safety of the entire device. Furthermore, the elastic support 12 also provides lateral support for the lifting cylinder 6, enhancing the overall structural stability. Several horizontally distributed support beams 4 are welded and fixed to the bottom of one side of the clamp assembly 2. These support beams 4 are evenly distributed in a fan shape at the bottom of the main support frame 1. This structure enhances the foundation stability of the entire device by adding multiple support points, allowing the main support frame 1 to be more firmly attached to the tower. Especially in the face of complex and variable wind environments in high-altitude areas, it effectively disperses forces, reduces single-point stress concentration, and thus reduces the risk of structural damage.

[0018] Working Principle: When using this high-altitude wind turbine single-blade aerial precision positioning auxiliary device, the main support frame 1 is first fixed to a suitable height position outside the main tower rod by the clamp assembly 2. The clamp assembly 2 can be fastened by diagonal bolts to ensure the overall structure is stable and reliable. Then, the bottom rotating motor of the reinforcing frame 3 is started to drive the rotating base 5 to rotate and adjust in the horizontal direction, so that the lifting bearing plate 7 is in the appropriate position. At the same time, the lifting cylinder 6 starts to work, driving the lifting bearing plate 7 to lift and lower in the vertical direction. Simultaneously, the elastic support 12 connected to it moves synchronously, playing a guiding and buffering role. At this time, the swing cylinder located in the recessed groove inside the lifting bearing plate 7 starts to act, driving the rotating swing plate 9 to swing around the hinge point. The rotating swing plate 9 drives the roller bracket 10 to move synchronously. The servo motor on the outer side of the roller bracket 10 drives the rotating shaft 11 to rotate. The threaded connecting column 13 welded in the middle of the rotating shaft 11 drives the threaded connecting ring 14 at the bottom of the dynamic auxiliary support 8 to rotate synchronously, realizing the attitude adjustment of the dynamic auxiliary support 8, thereby completing a series of auxiliary blade aerial positioning operation procedures.

[0019] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
