Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine blades, and in particular to a wind turbine blade elevation tool. Background Technology

[0002] Wind power generation is a renewable energy technology that converts wind energy into electrical energy. Wind turbine blades are crucial devices for capturing wind energy. A wind turbine blade is a long, narrow structure that tapers from its root to its tip. At the root of the blade is a base cylinder, one end of which is connected to the wind turbine tower via root bolts, and the other end connects to the fan blade section. As the blade transitions from the base cylinder to the fan blade section, its shape gradually widens, forming a larger fan-shaped area. The fan blade section is typically designed with a streamlined shape to reduce air resistance and improve efficiency.

[0003] As an important component of wind power generation, wind turbine blades require regular maintenance. However, wind turbine blades are usually installed at the top of wind turbine towers, which is a considerable distance from the ground. When maintenance personnel work on the cut-edge platform or the surface of the blade, they are prone to accidents such as falls, injuries, and even death.

[0004] CN217434235U provides a working fixture for the root of wind turbine blades, mainly including front and rear support frames, a crossbar, and an operating platform. The front support frame is fixed to the bolt holes at the blade root by bolts, and the rear support frame is supported inside the blade. One end of the crossbar is connected to the front support frame, and the other end passes through a manhole on the blade root to enter the blade and connect to the rear support frame. The operating platform is slidably mounted on the crossbar and can move horizontally along the crossbar. This ultimately enables installation work in the special working space of the blade. However, this device cannot be used on the outside of the blade; it is only suitable for work inside the blade root. Furthermore, the fixture is only fixed to the blade root bolt holes by two bolts, which is prone to deformation, resulting in an unstable fixture. Utility Model Content

The terms "upper," "lower," "front," "rear," "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or part referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be understood that such data can be interchanged where appropriate for the embodiments of this utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0024] This utility model provides an embodiment of a climbing fixture suitable for wind turbine blades, such as... Figures 1-4As shown, it includes a pair of first protection systems and a pair of second protection systems; the pair of first protection systems are symmetrically and at the same height on both sides of the root of the wind turbine blade, and the pair of second protection systems are symmetrically and at the same height on both sides of the root of the wind turbine blade, with the first and second protection systems on one side of the root of the wind turbine blade connected; the first protection system includes a first arc steel plate 1, a first angled steel pipe 2, and a first column 3; the second protection system includes a second angled steel pipe 4 and a second column 5; the first arc steel plate 1 is fixed to the flange at the root of the wind turbine blade; the first angled steel pipe 2 and the second angled steel pipe 4... Each pipe 4 includes a long side and a short side; the long side of the first angled steel pipe 2 is arranged along the length of the wind turbine blade, and a gap is left between the long side of the first angled steel pipe 2 and the wind turbine blade; the short side of the first angled steel pipe 2 is fixed to the first arc steel plate 1, and the long side of the first angled steel pipe 2 is fixed to the first column 3; the long side of the second angled steel pipe 4 is arranged along the length of the wind turbine blade, and a gap is left between the long side of the second angled steel pipe 4 and the wind turbine blade; the short side of the second angled steel pipe 4 is fixed to the first column 3, and the long side of the second angled steel pipe 4 is fixed to the second column 5; both the first column 3 and the second column 5 are vertical.

[0025] The gap between the long side of the first angled steel pipe 2 and the wind turbine blade, and the gap between the long side of the second angled steel pipe 4 and the wind turbine blade, allow the safety lock to slide on the first angled steel pipe 2 or the second angled steel pipe 4.

[0026] In use, the various components of the climbing equipment are assembled sequentially starting at the base of the wind turbine blade. After donning safety clothing, the worker connects one end of the safety rope buckle to the safety clothing, while the other end buckle can be fastened to either the first angled steel pipe 2 or the second angled steel pipe 4, depending on the work position. This allows the worker to walk on the cutting platform or the blade surface to perform grinding, inspection, and other operations. The safety buckle allows for free sliding on the angled steel pipes, enabling the worker to work freely on the blade and effectively preventing falls, thus ensuring worker safety.

[0027] Generally, to ensure the stability of the entire tooling, the first protective system is equipped with at least 3 first angled steel pipes 2 on one side, and the second protective system is equipped with at least 3 second angled steel pipes 4 on one side.

[0028] Generally, the short side lengths of the first angled steel pipe 2 and the second angled steel pipe 4 are 50-100cm. This reserved length on the short side facilitates both the fixed connection between the short side and the arc-shaped steel plate and the sliding of the safety lock. The sum of the long sides of the first angled steel pipe 2 and the second angled steel pipe 4 is less than or equal to the length of the base cylindrical section of the wind turbine blade, ensuring that workers have sufficient working area on the blade.

[0029] Generally, the first column 3 includes, from top to bottom, a second arc-shaped steel plate 6, a first column steel pipe 7, and a bottom support 8. The inner diameter of the second arc-shaped steel plate 6 is larger than the outer diameter of the wind turbine blade at its location. The second arc-shaped steel plate 6 has pre-drilled holes 9 corresponding to the connection of the first angled steel pipe 2. The end of the long side of the first angled steel pipe 2 passes through the holes 9 and is fixed by a fixing pin. A pin sleeve 13 is pre-drilled on one side of the second arc-shaped steel plate 6. The short side of the second angled steel pipe 4 is inserted into the pin sleeve 13 to realize the connection between the first protection system and the second protection system. The second arc-shaped steel plate 6 and the first column steel pipe 7, as well as the first column steel pipe 7 and the bottom support 8, are all welded together.

[0030] Generally, the second column 5 consists of a third arc steel plate 10, a second column steel pipe 11, and a bottom support 8 from top to bottom. The inner diameter of the third arc steel plate 10 is larger than the outer diameter of the wind turbine blade at its location. The third arc steel plate 10 has pre-drilled holes corresponding to the connection with the second angled steel pipe 4. The end of the long side of the second angled steel pipe 4 passes through the hole 9 and is fixed by a fixing pin. The third arc steel plate 10 and the second column steel pipe 11, as well as the second column steel pipe 11 and the bottom support 8, are all welded together.

[0031] In a preferred embodiment, both the first angled steel pipe 2 and the second angled steel pipe 4 are L-shaped square tubes. The angle of the first angled steel pipe 2 faces outward from the wind turbine blade, and the angle of the second angled steel pipe 4 faces inward from the wind turbine blade. By setting the angles of the steel pipes in opposite directions, the entire fixture fits more closely with the part of the wind turbine blade that gradually transitions from the base cylinder to the fan blade.

[0032] In a preferred embodiment, the holes 9 are evenly distributed on the first arc steel plate 1 and the third arc steel plate 10, so that the first angled steel pipe 2 and the second angled steel pipe 4 can be arranged at equal intervals and uniformly to achieve the force balance of the entire tooling.

[0033] In a preferred embodiment, the second column steel pipe 11 is an angled steel pipe with reinforcing ribs 12 provided on it. The two ends of the reinforcing ribs 12 are welded to the two angled sides of the second column steel pipe 11. The arrangement of the reinforcing ribs 12 can increase the local stiffness of the second column 5, thereby improving the load-bearing capacity of the entire climbing equipment structure.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of implementation of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and all such improvements and modifications should be covered within the protection scope of this utility model.
