Embodiment

[0025] Such as Figure 1-3 As shown, the yaw mechanism of the sling of the present invention is arranged at both ends of the main beam 103 of the fan blade sling, and plays the role of adjusting the posture of the fan blade. The vehicle frame 45 of the yaw mechanism 101 is hinged to the bracket assembly 102 of the fan blade spreader through pins, and plays the role of carrying and fixing the fan blades.

[0026] The yaw mechanism 101 includes a driving trolley 4, a circular arc-shaped track 2 and a corresponding arc-shaped rack 3; the arc-shaped track 2 is fixed on the main beam 103 by bolts.

[0027] The driving trolley 4 includes a motor 41 , a speed reducer 46 , an axle 42 , a bearing seat 43 , a toothed roller 44 and a vehicle frame 45 . The speed reducer 46 is fixed on the vehicle frame 45; the two ends of the axle 42 are respectively provided with a bearing seat 43, and the bearing seat 43 is nested on the vehicle frame 45 to play the role of supporting the bearing.

Abstract

The invention discloses a deflection mechanism of a lifting appliance. The deflection mechanism comprises a drive trolley, an arc-shaped arc rail and an arc gear rack corresponding to the arc rail. The drive trolley comprises a motor, a speed reducer, an axle, bearing pedestals and tooth-shaped rollers. The output end of the motor is connected with the speed reducer. The axle transversely penetrates an output hole of the speed reducer, an angle of 90 degrees is formed by the axle and an output shaft of the speed reducer, and the axle is driven by the speed reducer to rotate. The tooth-shaped rollers are fixed to the two ends of the axle. Each tooth-shaped roller comprises a tooth-shaped roller upper cylindrical face and a tooth-shaped roller upper gear, wherein the tooth-shaped roller upper cylindrical face is engaged with the arc rail, and the tooth-shaped roller upper gear is engaged with the arc gear rack. When used for mounting and demounting of fan blades by the fan blade lifting appliance in an high-altitude unmanned state, the deflection mechanism of the lifting appliance assists in adjusting the postures of the fan blades; the deflection mechanism is simple in overall structure and convenient to use; and compared with an existing deflection mechanism, the phenomenon that clamping appears due to the fact that the gravity center of a hanging object deflects is not prone to happening.

Description

technical field [0001] The invention relates to a yaw mechanism, in particular to a yaw mechanism for assisting the adjustment of the attitude of the blade when the blade spreader is installed and removed in the high-altitude unmanned state, and belongs to the field of auxiliary tools for the blade spreader . Background technique [0002] There are two main ways to lift the wind blades, one is integral lifting suitable for small wind turbine blades hoisting, and the other is split stepwise lifting suitable for large wind turbine blades hoisting. [0003] Since wind turbines are mostly installed in land or ocean areas with abundant wind resources, relatively large wind blades are mostly used at sea, and it is extremely inconvenient to lift or disassemble the wind blades. With the gradual increase of wind turbines and the further increase of installed capacity, there are also different technical requirements for the hoisting process and spreaders for lifting wind blades.
