Description

Technical Field

[0001] This invention relates to the field of wind turbine maintenance auxiliary technology, and in particular to an automatic climbing wind turbine ring maintenance platform. Background Technology

[0002] Wind turbines are exposed to the sun and rain all year round, which causes rust and corrosion on the outer surface of their towers. Inspection, maintenance and repair of the outer surface of the towers require the use of maintenance platforms. At present, maintenance platforms need to be constantly adjusted and rotated during operation to change the working position in order to achieve all-round maintenance. This not only makes the maintenance operation cycle long and costly, but also increases the instability of the maintenance platform and the risks to the operators.

[0003] Currently, the maintenance and upkeep of ultra-tall, large wind turbine nacelles, blades, and towers lacks specialized equipment. Traditional methods involve point-to-point operation using large cranes, which is difficult and unsafe. While imported equipment has been widely used in recent years for auxiliary work, specialized wind turbine maintenance equipment, especially equipment that integrates the maintenance and upkeep of wind turbine towers, nacelles, and blades, remains lacking.

A mounting groove parallel to the central axis of the platform is provided below the platform. The mounting groove is provided with a sliding rail and a positioning hole. The blade maintenance base 7013 is a plate structure with a hollow center. A mounting groove parallel to the central axis of the base is provided above the vertical plate of the blade maintenance base 7013. A sliding rail and a positioning hole are provided in the mounting groove. A rail parallel to the central axis of the base is provided below the vertical plate of the base.

[0048] The process of using an automatic climbing wind turbine ring maintenance platform is as follows:

[0049] like Figure 9-11 As shown, this device is installed on the outside of the wind turbine tower. When maintenance personnel are working on the nacelle, the nacelle maintenance mechanism support scissor structure 6016 and the blade maintenance mechanism support scissor structure 7018 extend simultaneously at a certain angle. After contacting the tower, the magnetic attraction devices of the nacelle maintenance mechanism support 6017 and the blade maintenance mechanism support 7017 are firmly attached to the tower. Subsequently, the nacelle maintenance mechanism support scissor structure 6016 continues to extend, causing the nacelle maintenance mechanism 1 to extend laterally to the designated position. The lifting scissor structure 6014 of the rear engine room maintenance mechanism extends, raising the engine room maintenance platform 6013 to a position flush with the engine room. Workers can enter the engine room through the platform for maintenance. If it is necessary to replace parts or engines in the engine room, the hook of the lifting structure 6011 can be extended into the engine room. The replacement parts are lifted out through the cooperation of the telescopic device and the hook. The parts are placed on the ground through the rotation of the lifting arm and the cooperation of the telescopic device. The new parts are then lifted back into the engine room for workers to repair.

[0050] like Figure 8As shown, when maintenance personnel are inspecting the blades, the nacelle maintenance mechanism support scissor structure 6016 and the blade maintenance mechanism support scissor structure 7018 extend simultaneously at a certain angle. After contacting the tower, the magnetic attraction devices of the nacelle maintenance mechanism support 6017 and the blade maintenance mechanism support 7017 are energized and firmly attracted to the tower. Subsequently, the blade maintenance mechanism support scissor structure 7018 continues to extend, causing the blade maintenance mechanism 4 to extend laterally to the designated position. Then, the blade maintenance mechanism lifting scissor structure 7020 extends, causing the blade maintenance platform 7012 to rise to the designated position. Maintenance personnel can move freely on the blade maintenance platform 7012 to inspect the blades, and the blade maintenance mechanism lifting scissor structure 7020 can be adjusted in height according to the needs of the maintenance personnel, allowing the maintenance personnel to work in any position.

[0051] like Figure 12 As shown, when maintenance personnel perform maintenance and repair work on the tower's exterior facade, they need to start from the top of the tower. That is, after the overall structure rises to the highest point, the central processing unit issues a descent command. Through the issued electrical signal, the drive structure drive wheel 4011, the retaining structure fixing component 3013, and the tightening structure fixing component 5012 support the main structure. The drive structure drive wheel motor works to start the drive structure drive wheel 4011, driving the overall structure to descend. During the descent, each electric cylinder continuously retracts. The tightening structure drive wheel 5019, in conjunction with the self-locking devices on each unit structure, continuously loosens the climbing main structure 3, but at the same time, the overall structure remains locked to the tower. The movement can be stopped at any time during the descent, allowing the overall structure to hold the tower tightly, so that maintenance personnel can perform maintenance and repair work on the tower's exterior facade on the circular maintenance platform 2.
