A special high-altitude work platform for wind power installation

Abstract

This application provides a dedicated high-altitude work platform for wind power installation, including a platform body. A T-shaped ring is rotatably connected inside the platform body, and a protective cover is fixedly mounted on the T-shaped ring. The protective cover has an oblique opening, and a circular ring is fixedly connected inside the protective cover and mounted on the platform body. The platform body and the circular ring are connected by a limiting mechanism. Through the cooperation between the circular ring and the limiting mechanism, when adjusting the position of the protective cover, simply stepping down on the footplate to its maximum extent releases the limiting effect on the protective cover. Then, rotating the protective cover adjusts its position. After adjusting the protective cover to its lowest point facing the inspection point, removing the foot from the footplate re-limits the protective cover. This process is very convenient, effectively improving installation efficiency, preventing maintenance personnel from falling backward, and aligning the lowest point of the protective cover with the inspection point further facilitates operation by maintenance personnel.

Technical Field

[0001] This utility model relates to the field of wind power installation technology, and in particular to a special high-altitude work platform for wind power installation. Background Technology

[0002] With the continuous growth of global demand for clean energy, wind power, as a sustainable energy solution, has been widely applied and rapidly developed. The scale of wind farms is constantly expanding, and the single-unit capacity of wind turbines is also continuously increasing, which brings many new challenges to the installation and maintenance of wind power equipment. As a key piece of equipment ensuring the safe and efficient installation and maintenance of wind power equipment, the technological development of specialized aerial work platforms for wind power installation is of great significance to the entire wind power industry.

[0003] A wind power installation-specific aerial work platform, disclosed in CN216922378U, includes a platform body. A protective cover is rotatably mounted on the upper end of the platform body. The front part of the protective cover is lower than the rear part. A latch is fixedly connected to the lower front end of the protective cover. A padlock is slidably fitted on the front part of the protective cover. A chain is fixedly connected to the lower end of the padlock. A tool latch is fixedly connected to the lower end of the chain. The protective cover includes a cover body, a swivel ring, a restraining hook, and a stop bar. The lower end of the cover body is fixedly connected to the upper end of the swivel ring.

[0022] A specialized aerial work platform for wind power installation includes a platform body 1. A T-shaped ring 3 is rotatably connected inside the platform body 1. A protective cover 2 is fixedly mounted on the T-shaped ring 3. The protective cover 2 has an angled opening. A circular ring 4 is fixedly connected inside the protective cover 2 and is mounted on the platform body 1. The platform body 1 and the circular ring 4 are connected by a limiting mechanism. The circular ring 4 contacts the upper surface of the platform body 1. By creating the angled opening on the protective cover 2, it can be shaped with a lower front and a higher back. When adjusting the position of the protective cover 2, the lower part of the protective cover 2 faces the maintenance point, making it easier for maintenance personnel to operate, while the higher back prevents maintenance personnel from tilting backward, ensuring safety.

[0025] Preferably, the limiting mechanism includes a right-angle plate 100 fixedly connected to the upper surface of the platform 1. A housing 5 is fixedly mounted on the outer end of the right-angle plate 100. A first sliding plate 61 and a second sliding plate 62 are slidably connected inside the housing 5. A stepping plate 7 is provided on the inner side of the housing 5, and the bottom surface of the stepping plate 7 is fixedly connected to the first sliding plate 61 and the second sliding plate 62 respectively. The two sliding plates 6 are reinforced by a connecting plate. The housing 5 has a groove inside that matches the sliding plates 6.

[0027] Preferably, a rotating shaft 8 is rotatably connected inside the housing 5, and a gear 9 is fixedly connected to the rotating shaft 8. A first toothed plate 11 and a second toothed plate 13 are respectively provided on both sides of the gear 9, and both the first toothed plate 11 and the second toothed plate 13 mesh with the gear 9. A first movable plate 10 is fixedly connected to the outer surface of the first toothed plate 11, and the first movable plate 10 is slidably connected inside the housing 5. The side of the first movable plate 10 away from the first toothed plate 11 is fixedly connected to the second sliding plate 62. In actual operation, the two sliding plates 6 are reinforced by a connecting plate, and a groove adapted to the sliding plates 6 is provided inside the housing 5.

[0028] See Figure 5 This utility model Figure 2 An enlarged schematic diagram of the structure at point A in the middle.

[0029] Preferably, two cylinders 18 are fixedly connected to the outer surface of the rotating shaft 8, and a torsion spring 19 is fixedly connected inside each of the two cylinders 18, with the other end of the torsion spring 19 fixedly connected to the inner wall of the housing 5. When the gear 9 rotates, it can drive the rotating shaft 8 and the cylinders 18 to rotate accordingly, and the rotation of the cylinders 18 can cause the torsion springs 19 to deform accordingly.

[0030] Preferably, a second movable plate 12 is fixedly connected to the outer surface of the second toothed plate 13, and a lifting plate 14 is fixedly connected to the upper surface of the second movable plate 12.

[0032] When adjusting the position of the protective cover 2, first step down on the footplate 7. The footplate 7 can drive the first sliding plate 61, the second sliding plate 62, the first moving plate 10, and the first toothed plate 11 to move downward. The downward movement of the first toothed plate 11 can drive the gear 9 to rotate. The rotation of the gear 9 can drive the rotating shaft 8 and the cylinder 18 to rotate accordingly. The rotation of the cylinder 18 can drive the torsion spring 19 to deform accordingly. The rotation of the gear 9 can also drive the second toothed plate 13 to move upward. The upward movement of the second toothed plate 13 can drive the lifting plate 14 and the limiting rod 15 to move upward. When the footplate 7 moves downward to its maximum extent... When the limit rod 15 moves out of the limit hole 17, the limit of the ring 4 and the protective cover 2 can be released. Then the position of the protective cover 2 can be adjusted so that the lower part of the protective cover 2 faces the inspection point. Then the foot is removed from the foot plate 7. At this time, under the action of the torsion spring 19, the gear 9 will rotate to the reset position. During the rotation of the gear 9 to the reset position, it will drive the first tooth plate 11 and the foot plate 7 to move upward, and the second tooth plate 13 and the limit rod 15 to move downward. Thus, the limit rod 15 will be inserted into the corresponding limit hole 17, and the protective cover 2 can be fixed again.
