Description
HERRAMIENTA PARA EL IZADO DE UNA PALA DE AEROGENERADOR TOOL FOR LIFTING A WINDER BLADE
La presente invención se refiere a una herramienta para el izado de una pala de
aerogenerador para el montaje de esta en el rotor de éste. La función de la invención es
doble: mejorar el comportamiento del citado útil, reduciendo la posibilidad de dañar la
pala durante el izado y, además, permitir izar la pala teniendo ésta la parte cóncava del
borde de salida posicionada hacia abajo, además de hacia arriba, como se hacía hasta
ahora.
The present invention relates to a tool for hoisting a wind turbine blade for mounting it on its rotor. The function of the invention is twofold: to improve the behavior of said useful, reducing the possibility of damaging the
shovel during lifting and, in addition, allow the blade to be lifted by having the concave part of the trailing edge positioned downwards, in addition to upwards, as was done until now.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Es conocido que las palas del aerogenerador se montan de una en una, elevando cada una hasta el rotor, ya montado en góndola que, a su vez, ya está montada sobre la torre. Para elevarlas hasta ahí, para montarlas, se emplea una grúa y una herramienta de elevación como la que se representa en la figura 1. Dicha herramienta consta, en esencia, de los siguientes componentes: It is known that the wind turbine blades are mounted one at a time, raising each one to the rotor, already mounted on a gondola which, in turn, is already mounted on the tower. To lift them up there, to assemble them, a crane and a tool are used. elevation as shown in figure 1. This tool consists, in essence, of the following components:
- - -
- unos ramales de cadenas, para su amarre a la grúa; chains of chains, for its mooring to the crane;
- - -
- un “balancín” que cuelga de dichos ramales de cadenas; -una eslinga que, colgando del “balancín”, amarra la parte de la pala más próxima a la raíz de ésta: Esta zona de la pala tiene forma aproximadamente cilíndrica; -un conjunto eslinga – “teja”, para amarrar la parte de la pala más alejada de la raíz: Esta zona de la pala tiene mayor anchura, y además incluye el borde de salida de la pala, que puede dañarse fácilmente, por lo que no debe amarrarse directamente con la eslinga, sino que necesita una mayor superficie de apoyo sobre la que repose la pala; Por ello, se introduce una placa curva de apoyo denominada “teja” por su forma, tal como se puede apreciar en las figuras 2 y 3. La “teja” está fabricada con un material compuesto de fibra de vidrio y resina, y su cara superior está recubierta por una espuma acolchada, para evitar dañar la pala. Consta de 2 ranuras, en ambos extremos, para que pase la eslinga. Además, incluye, en ambos extremos, sendos tubos de protección de material elástico. Las palas suelen llegan al parque eólico agrupadas en contenedores de pala, o bien de una en una en los útiles de transporte de pala individual. Las palas que van en contenedor están posicionadas en éste de forma que algunas van con la parte cóncava del borde de salida hacia arriba y las otras van giradas, es decir, con la parte cóncava del borde de salida hacia abajo. En el parque eólico, se descargan a "rocker" hanging from said chain branches; -a sling that, hanging from the “rocker”, ties the part of the blade closest to the root of this: This area of the blade has an approximately cylindrical shape; -a sling set - “tile”, to tie the part of the shovel furthest from the root: This area of the blade has greater width, and also includes the trailing edge of the shovel, which can be easily damaged, so it should not be tied directly with the sling, but needs a larger support surface on which the blade rests; Therefore, a curved support plate called “tile” is introduced due to its shape, such as can be seen in figures 2 and 3. The "tile" is made of a composite fiberglass and resin material, and its Upper face is covered by a padded foam, to avoid damaging the blade. It consists of 2 slots, at both ends, for the sling to pass. It also includes, in both ends, two protective tubes of elastic material. The shovels usually arrive at the wind farm grouped in shovel containers, or one by one in the individual shovel transport tools. The shovels that go in container are positioned in this one so that some go with the concave part of the trailing edge facing up and the others are turned, that is, with the concave part of the trailing edge down. In the wind farm, they are unloaded
sobre una superficie horizontal y se apoyan en unos corchos de poliestireno. La descarga de las palas sobre dichos corchos se hace directamente, manteniendo las posiciones que traían en el contenedor. Éste es uno de los inconvenientes importantes de la herramienta de izado: La “teja” permite el apoyo de la pala con la parte cóncava del borde de salida posicionada hacia arriba, tal como se aprecia en la sección de la figura 3; Sin embargo, si dicha parte cóncava está posicionada hacia abajo, no tiene suficiente superficie de apoyo sobre la “teja”, lo que aumenta mucho el riesgo de que se dañe la pala, sobre todo en su borde de salida. on a horizontal surface and rely on polystyrene corks. The unloading of the shovels on said corks is done directly, maintaining the positions that they brought in the container. This is one of the important drawbacks of the lifting tool: The "tile" allows the support of the blade with the concave part of the trailing edge positioned upwards, as can be seen in the section of figure 3; However, if said concave part is positioned downwards, it does not have enough support surface on the "tile", which greatly increases the risk of the blade being damaged, especially at its trailing edge.
