A traction suspension device for wind turbine maintenance

Abstract

A traction suspension device for fan repair belongs to the technical field of fans. The traction suspension device comprises a pulley block hanger, a working platform, and a depended wheel mechanism, fixed pulley mechanisms, roll mechanisms and steel wire ropes, all of which are installed on the working platform. The pulley block hanger is fixed on an engine room above the working platform. The working platform is of an 'L'-shaped frame structure, and forms a frame with an upper layer and a lower layer. The end, with two layers of frames, of the working platform is near a tower, and the side is connected with the depended wheel mechanism which can extend or retract and is supported on the tower. The upper layer of frame and the lower layer of frame are respectively equipped with one roll mechanism and one fixed pulley mechanism. The steel wire ropes on rolls are respectively connected with pulleys on the pulley block hanger. The fixed pulleys on the upper and lower layers of the 'L'-shaped frame are fixedly connected to the working platform. The roll mechanisms roll the steel wire ropes up and down to enable the traction suspension device to go up and down. The traction suspension device of the structure has a light and flexible structure, and is applicable to maintaining and repairing the exterior facades of towers, the outer surfaces of engine rooms and the blades of fans of various wind-driven generators.

Description

technical field [0001] The invention relates to a traction and suspension device for fan maintenance, belonging to the technical field of fan. In particular, it relates to a maintenance operation applied to blades, nacelles and towers of various wind power generators, and is suitable for working devices attached to the outer facade of wind power generator towers. Background technique [0002] With the shortage of energy, wind power generators are developing rapidly. There is a lack of special construction equipment for the maintenance of the inside and outside of the ultra-high large-scale wind turbine tower, the nacelle and the blades. A large number of imported equipment is used in the construction, or replaced by traditional construction equipment with a low safety factor and low work efficiency, which seriously affects my country's ultra-high The improvement of the technical level of construction equipment has hindered the supporting development of the ultra-high buildin...

There is a lack of special construction equipment for the maintenance of the inside and outside of the ultra-high large-scale wind turbine tower, the nacelle and the blades. A large number of imported equipment is used in the construction, or replaced by traditional construction equipment with a low safety factor and low work efficiency, which seriously affects my country's ultra-high The improvement of the technical level of construction equipment has hindered the supporting development of the ultra-high building construction industry

The maintenance and repair equipment technology for the facade of the wind turbine tower, the outer surface of the nacelle and the blades of the wind turbine is still blank in China

However, the contradiction between the amount of maintenance work and maintenance equipment that has been presented year by year continues to intensify, which will eventually restrict the healthy development of my country's wind power energy.

Therefore, a variable-diameter attachment device for fan maintenance is designed to solve the actual maintenance and repair of various types of wind turbine tower facades, cabin outer surfaces, and fan blades.
