Wind power blade repair platform

Abstract

The invention discloses a wind power blade repair platform in the field of repair and detection of wind driven generators. The wind power blade repair platform comprises an ascending and descending platform arranged in a way of corresponding to wind power blades, outer side fences are arranged on the peripheral edges of the ascending and descending platform; an installing frame is fixedly arranged above the ascending and descending platform through a supporting mechanism; and a plurality of lifting motors are arranged on the outer side fences; a plurality of steel wire ropes are arranged corresponding to each lifting motor; the upper end of each steel wire rope is fixed to the top of a wind driven generator; the steel wire ropes pass through the corresponding lifting motors after being guided by the corresponding pulley guide mechanisms; the lower ends of the steel wire ropes are fixed; the outward sides of the wind power blades are set into arc shapes; a climbing guide mechanism is arranged on the side, corresponding to the outward sides of the wind power blades, of the installing frame; and a tilt angle sensor is arranged on the ascending and descending platform; and the tilt angle sensor and each lifting motor are electrically connected with a control system. The wind power blade repair platform provided by the invention can keep horizontal vertical ascending and descending along the wind power blades, the safety is higher, the operation is convenient, and the moving range is wider.

Description

technical field [0001] The invention belongs to the field of wind power generator maintenance and detection, and in particular relates to a wind power blade maintenance platform. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The working principle of the wind turbine is relatively simple. The wind blade rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind blade shaft. Usually, the tower of the wind turbine is erected in a place with abundant wind resources, such as a place without obstacles, that is, it needs to be erected in a relatively remote place. Because wind turbines are exposed to the external environment all the year round, the surface of the wind turbine blades is provi...

AI Technical Summary

Problems solved by technology

[0003] The maintenance platform for wind turbine blades in the prior art usually moves up and down along the surface of the tower, and it is necessary to adjust the position of the blades to get close to the position of the maintenance platform to facilitate personnel maintenance. The disadvantage is that the existing large-scale wind turbines Some of the heights are as high as hundreds of meters. After the staff have been lifted into the air through the platform, it is very dangerous to start the wind turbine to adjust the position and angle of the blades; ; The clamping device is used to fix the maintenance platform and the tower, and the selected clamping device has a complex structure
