Problems solved by technology
The segmented installation reduces the requirements for transportation and construction sites, but it has high requirements for the alignment of the blades during installation. Often the alignment of the blades at high altitude will waste a lot of time and prolong the construction period.
[0004] However, the existing tooling for stabilizing blades can only be used for specific models and cannot be used widely. Its versatility is low, which increases the operating costs of wind farm installation and reduces the efficiency of on-site installation.

Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation to the present invention.
[0026] A fan blade positioning device that can move on the boom, such as figure 1 As shown, the trolley frame 1 is included, and the trolley frame 1 is slidably connected to the boom along the length direction of the boom; the telescopic arm 2 is arranged on both sides of the trolley frame 1 and the telescopic arm 2 is controlled to extend out of the trolley frame 1. Two telescopic arms 2 are perpendicular to the length direction of the boom and are mutually staggered. The two telescopic arms 2 are all worn with wire ropes 3. The lower ends of the two wire ropes 3 are fixed with a fan blade hoisting frame 31 for positioning the fan blades. In this embodiment, two slide rails 0 arranged along its length direction are welded on both sides of the boom, and...

The invention discloses a fan blade locating device capable of moving on a lifting arm, and relates to the technical field of fan blade installing. The problems that tooling of an existing stabilizerblade can be only used for specific models, popularization using can not be realized, and universality is low are solved. A trolley frame of the device is slidably and movably connected to the liftingarm in the length direction of the lifting arm; the two sides of the trolley frame are provided with extensible arms, and driving devices for controlling the length of the parts, extending out of thetrolley frame, of the extensible arms; steel wire ropes both penetrate through the extensible arms, and a fan blade lifting frame for locating the fan blade is fixed to the upper end of the two steelwire ropes; and the extensible arms and / or the trolley frame is connected to a diversion pulley block used for changing the penetrating directions of the steel wire ropes, and the upper ends of the steel wire ropes are arranged in the length direction of the lifting arm. The fan blade locating device capable of moving on the lifting arm is suitable for the locating installation of all kinds of offshore wind turbine model blades and is applied to precise adjustment of single fan blade installation and dismounting of all offshore wind turbines, the various operating costs of wind field installation are saved effectively, and installation efficiency on site is improved.
Description
technical field [0001] The invention relates to the technical field of fan blade installation, in particular to a fan blade positioning device that can move on a boom. Background technique [0002] With the continuous development of the global offshore wind power industry, various types of wind turbines have appeared in the market, and the installation process of wind turbines has been continuously improved. Types of installation: 1. Integral installation, where three blades and hubs are assembled on a land dock or on a ship, then the overall hoisting of the wind field and assembly of the main engine are carried out; On the field, install the hub to the main engine, and then install the blades on the hub one by one. [0003] Integral installation, due to the relatively large diameter of the wind rotor, the overall installation requires a large construction site and transportation equipment, and the requirements for the hoisting platform are relatively high during hoisting. ...
