Problems solved by technology

There is no corresponding product in China for the wind wheel turning device with ultra-high torque in an unbalanced state. The imported turning device has complex structure, cumbersome installation, high cost, and difficult maintenance, and an installation platform and mechanical interface need to be reserved. The structure of fan products needs to be greatly adjusted

Embodiment

[0045] A wind turbine turning device, such as Figure 1-Figure 2 As shown, it includes a base 1, the base is provided with a variable connection block 2, and a rotating arm 3 is also provided on the base. A rotating disc 5 is also provided to realize the rotation of the rotating arm. The rotating disc is rotatably assembled on the base, and the rotating arm can be driven to rotate by the rotating disc. Connect the hook and the wind system.

[0046] In this embodiment, the current problem that the blades of wind turbines need to be hoisted and assembled after the assembly is completed is solved by the turning device of the generator set. The turning device can realize the assembly of the blades after assembling the hub. The design effectively improves the safety performance of the assembly, especially in the process of hoisting the entire blade device, the three blades plus the hub increase the weight of the hoisting, and the risk factor is very high, and this design is effect...

Embodiment 2

[0058] A method for hoisting a single blade of a wind turbine, such as Figure 3-Figure 19 shown, including the following steps:

[0059] S1, such as Figure 4 and Figure 5 As shown in the figure, install the turning device of the wind turbine, use the hook and the wind system to rotate it from the initial state of the hub, so that the axis of the installation position of the first blade is in a horizontal state, and after locking the wind wheel, hang it horizontally and install the first blade. blade;

[0060] S2, such as Image 6 As shown, the wind turbine nacelle rotates 180° around the center of the tower (that is, the yaw of the unit is 180°);

[0061] S3, such as Figure 7-Figure 10 As shown in the figure, connect the wind sweeping system to the hanging point connecting device of the turning device, and use the gravity action of the installed first blade and the wind sweeping system to pull the turning device, so that the hub rotates 60°, so that the second blade i...

Abstract

The invention discloses a turning device and single-blade hoisting method of a wind power generating set, belonging to the technical field of wind power devices; comprising a base, the base is provided with a variable connection block, and the base is also provided with a rotating arm, and the rotating arm is powered by power. The system can be rotated up and down on the base, and there is a rotating disk between the base and the rotating arm to realize the rotation of the rotating arm; the present invention can realize the wind wheel turning with super high torque in the unbalanced state, so that it can be turned with the blade The axis of the docked hub mounting surface is adjusted to the horizontal position in turn, thereby realizing the horizontal hoisting of a single blade of the wind turbine. At the same time, the device of the present invention has strong versatility and is suitable for a variety of wind turbines of different sizes; the structure is simple and easy to install. The operation is convenient and the maintenance is simple. It can turn the wind rotor with ultra-high torque in the unbalanced state, and realize the single-blade hoisting of the wind turbine in the horizontal position.

Description

technical field [0001] The invention relates to a turning device of a wind generator set and a method for hoisting a single blade, belonging to the technical field of wind power devices. Background technique [0002] At present, the wind turbine blades are installed on the ground platform of the wind farm or the offshore operation platform to assemble the three blades and the hub to form the wind rotor as a whole, and then use the crane to lift the wind rotor as a whole to high altitude to complete the docking work of the wind rotor. [0003] The single-blade hoisting technology changes the traditional wind turbine assembly mode. The blade and the hub are upgraded from ground assembly to aerial pairing. A single blade is hoisted separately and docked with the hub in the air. Generally, the three blades of the fan need to be hoisted three times. The assembly process requirements for single-blade hoisting are relatively high. In order to reduce the high-performance requirement...
