Description

Technical Field

[0001] This utility model belongs to the field of wind power hybrid tower maintenance technology, and more specifically, this utility model relates to a ring-shaped automatic lifting device for wind power hybrid towers. Background Technology

[0002] As the supporting structure of wind turbine generators, wind turbine towers are exposed to the complex outdoor environment for extended periods, making them prone to surface cracks, corrosion, and concrete spalling, requiring regular inspection and repair. Current tower maintenance work mainly relies on manual climbing, suspended platforms, or specialized lifting platforms, which presents the following problems: Poor adaptability: Wind turbine towers are mostly tapered structures with varying diameters (larger diameter at the bottom and smaller diameter at the top). Traditional lifting devices cannot keep the tower wall in place throughout the entire process, which can easily cause swaying and affect operational stability. Low safety: Manual climbing or suspended platform operations are greatly affected by high-altitude wind loads, posing a risk of falling. Limited functionality: Existing devices are mostly used only for transporting personnel or equipment. Testing requires additional testing equipment, and repair requires secondary operations, resulting in low efficiency. Insufficient flexibility: Temporary work equipment is cumbersome to assemble and disassemble, while permanent installation equipment has fixed functions, making it difficult to meet both single-time testing and regular transportation needs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a ring-shaped automatic lifting device for wind power hybrid towers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An annular automatic lifting device for a wind turbine hybrid tower includes an annular body that is fitted around the wind turbine hybrid tower. The outer side wall of the body is provided with an annular slide rail, which is fixedly connected to the outer side wall of the body. The inner side wall of the body is provided with three layers of lifting mechanisms. Each lifting mechanism includes a clamp and a horizontal telescopic hydraulic rod, wherein the clamp and the horizontal telescopic hydraulic rod are connected, and the connected lifting mechanisms are connected by a vertical telescopic hydraulic rod.

[0005] This utility model discloses a ring-shaped automatic lifting device for wind turbine hybrid towers, wherein the trajectory of the ring-shaped slide rail is perpendicular to the tower axis. This utility model discloses a ring-shaped automatic lifting device for wind power hybrid towers. The main body is a detachable truss structure, and the size of the main body can be designed according to the radius of the wind power hybrid tower.

[0006] This utility model discloses a ring-shaped automatic lifting device for wind power hybrid towers, wherein a mounting platform is provided on the ring slide rail, and the mounting platform can slide on the ring slide rail.

[0007] Compared with the prior art, the present invention has the following advantages: This device, through its own lifting function and the robot it carries, solves the problem of the original need to carry personnel up and down the wind turbine tower via a basket and seat for inspection and maintenance. This improves the efficiency of wind turbine tower inspection and maintenance, reduces costs, and most importantly, reduces the dangers of personnel working at height.

[0008] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0009] The following is a brief explanation of the contents of each of the accompanying drawings and the markings in the drawings: Figure 1 This is a schematic diagram of the present invention; Figure 2 This is a top view of the present invention; The following are marked in the diagram: 1. Horizontal telescopic hydraulic rod; 2. Clamp; 3. Vertical telescopic hydraulic rod; 4. Main body; 5. Wind power hybrid tower; 6. Circular slide rail. Detailed Implementation

[0010] The following description, with reference to the accompanying drawings, further details the specific implementation methods of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution.

[0011] like Figure 1 and Figure 2 The diagram illustrates a ring-shaped automatic lifting device for a wind turbine hybrid tower, comprising a ring-shaped body 4, which is fitted around the wind turbine hybrid tower 5. The outer wall of the body 4 is provided with a ring-shaped slide rail 6, which is fixedly connected to the outer wall of the body 4. The inner wall of the body 4 is provided with three layers of lifting mechanisms. Each lifting mechanism includes a clamp 2 and a horizontal telescopic hydraulic rod 1, wherein the clamp 2 and the horizontal telescopic hydraulic rod 1 are connected. The connected lifting mechanisms are connected by vertical telescopic hydraulic rods 4. The trajectory of the ring-shaped slide rail 6 is perpendicular to the tower axis. The body 4 is a detachable truss structure, and its size can be designed according to the radius of the wind turbine hybrid tower 5. A mounting platform is provided on the ring-shaped slide rail 6, which can slide on the ring-shaped slide rail 6.

[0012] Working principle and method The annular main body 4 uses the lowest horizontal telescopic hydraulic rod 1 to hold the lowest clamp 2 tightly against the tower wall, providing friction to support the telescopic upright to move upward. After reaching the maximum stroke, the highest horizontal telescopic hydraulic rod 1 is driven laterally to hold the highest clamp 2 tightly against the tower wall, providing friction. The clamps 2 of the two lower layers are then loosened, and the vertical telescopic hydraulic rod 3 is used to pull the two lower layers of structure up. Finally, the horizontal telescopic hydraulic rod 1 is used to hold the tower tightly.

[0013] Upward walking flowchart 1. The lowest horizontal telescopic hydraulic rod 1 pressurizes the tower, causing the lowest clamp 2 to grip the tower wall and provide friction. 2. Loosen the uppermost and middle layer transverse hydraulic telescopic rods 1 to separate the middle clamp 2 and the upper clamp 2 from the tower wall; 3. Activate the vertical telescopic hydraulic rod 3 to move the middle and upper platforms upwards; 4. Once the upper and middle platforms are in the appropriate positions, lock the vertical telescopic hydraulic rod 3. Activate the upper and middle horizontal telescopic hydraulic rods 1 to press the clamp 2 tightly against the tower wall and provide sufficient friction (considering that the tower is generally smaller at the top and larger at the bottom, the clamp is less likely to slip off). Unlock the vertical telescopic hydraulic rod 3, activate the vertical telescopic hydraulic rod 3 to pull the lower platform up to the appropriate position, lock the vertical telescopic hydraulic rod 3, and activate the horizontal telescopic hydraulic rod 1 to press the clamp 2 tightly against the tower wall.

[0014] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
