Problems solved by technology

There are a lot of unreliability in this kind method, for example: firstly, when running into the weather of bigger wind force, the ground personnel can't easily adjust the ground control rope; This increases the risk of the wind blade swinging in the air; again, because the lifting and control ropes are flexible, there is relative motion between the wind blade and the wind turbine at the moment of installation contact, which is prone to collision damage

Abstract

The invention discloses an aerial posture adjusting device for fan mounting and dismounting. A clamping mechanical arm device is hoisted on a lazy arm through a second traction winch and a second bearing cable, the front end of a rigidity arm is hoisted on the lazy arm through a first traction winch and a first bearing cable, and the rear end of the rigidity arm is rotationally connected with the lazy arm. Posture adjusting connecting rods are connected with the front end of the rigidity arm. One end of one telescopic drive assembly is fixedly connected with the clamping mechanical arm device, and the other end of the telescopic drive assembly is rotationally connected with the posture adjusting connecting rod. One end of the other telescopic drive assembly is rotationally connected with the clamping mechanical arm device, and the other end of the other telescopic drive assembly is rotationally connected with the posture adjusting connecting rod. The two telescopic drive assemblies, the first traction winch and the second traction winch are remotely controlled through one remote control device. According to the aerial posture adjusting device, blade grabbing, elevating, positioning and posture fine adjusting are achieved in a complete remote control manner, operation is convenient, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to an air attitude adjustment device for assembling and disassembling a fan blade, which is used for adjusting the attitude of the fan blade in the process of assembling and disassembling the fan blade, so that the installation surface of the fan blade is matched with the installation surface of the wind turbine. Background technique [0002] The air attitude adjustment when the fan blade is installed, at present, most of the methods used at home and abroad are to use at least two flexible control steel cables to pull the fan blade hoisting frame to keep the fan blade in the air in a basic horizontal state. This method can only control the direction of the fan blade to hang. The control of the movement of the outside of the arm also requires multiple ground control ropes to ensure that the fan blades do not swing in the direction of the boom or rotate around the boom. There are many unreliability in this method, for example: first...
