Description
Plataforma para mantenimiento de aerogeneradores dotada de sistemas de guiado, sujeción y regulación.Wind turbine maintenance platform equipped with guidance, support and regulation systems.
La invención se engloba dentro del campo de las energías renovables y más concretamente se refiere a una plataforma para mantenimiento de aerogeneradores dotada de sistemas de guiado, sujeción y regulaciónThe invention falls within the field of renewable energy and more specifically refers to a platform for maintenance of wind turbines equipped with guidance systems, clamping and regulation
La energía eólica ha experimentado en los últimos años un gran desarrollo, implantándose un elevado número de Parques Eólicos. Este desarrollo comercial ha ido paralelo a grandes avances técnicos, con la aparición de nuevos modelos de aerogeneradores de cada vez mayor potencia, pero no se ha dedicado sin embargo el mismo esfuerzo al área de mantenimiento y reparación de los equipos. El componente que presenta mayor desgaste de los aerogeneradores son las palas, principal constituyente del rotor o hélice motriz. Esto es debido a las acciones meteorológicas principalmente.Wind power has experienced in the recent years a great development, implanting a high number of Wind farms This commercial development has paralleled large technical advances, with the emergence of new models of wind turbines of increasing power, but not dedicated however the same effort to the maintenance and repair area of the teams. The component that presents greater wear of the wind turbines are the blades, the main constituent of the rotor or motor propeller This is due to weather actions. mainly.
Por este motivo se han desarrollado en los últimos años una serie de equipos de mantenimiento diseñados para acceder a las palas para su completa reparación o inspección. Del análisis realizado sobre estos diseños se observa que presentan características geométricas diferenciadas, pero todos los equipos requieren la disposición en bandera o posición de parada de la pala totalmente vertical hacia abajo. Esta colocación ideal de trabajo de la pala no resulta sin embargo la más habitual, ya que para realizar las tareas de mantenimiento los protocolos de seguridad a aplicar requieren el accionamiento de los frenos mecánicos y por lo general esto implica una desviación de la vertical de aproximadamente entre 8-10° que no permite la colocación de las plataformas convencionales.For this reason they have developed in the recent years a series of maintenance equipment designed to Access the blades for complete repair or inspection. Of the analysis performed on these designs is observed to present differentiated geometric characteristics, but all equipment require the provision in flag or stop position of the shovel fully vertical down. This ideal job placement of however, the blade is not the most common, since to perform maintenance tasks security protocols to apply require the actuation of the mechanical brakes and usually this implies a vertical deviation of approximately between 8-10 ° that does not allow the placement of conventional platforms.
Por este motivo resulta de gran interés desarrollar equipos de mantenimiento dotados de sistemas de anclaje y regulación que permitan operar en los ángulos de inclinación de pala que realmente se producen.For this reason it is of great interest develop maintenance equipment equipped with anchoring systems and regulation that allow to operate in the inclination angles of Shovel that really occur.
El sistema que se desarrolla en este documento permitirá el montaje y operación de plataformas de mantenimiento en las condiciones de trabajo reales y será de aplicación a diversos modelos de aerogeneradores en función de las configuraciones seleccionadas. Se trata además de un sistema rápido y seguro, tanto en su operación como en su montaje y desmontaje, que no requiere de personal especializado, quedando así justificado el interés de este sistema de anclaje, guiado y regulación.The system that is developed in this document will allow the assembly and operation of maintenance platforms in the actual working conditions and will apply to various wind turbine models depending on the configurations selected. It is also a fast and safe system, both in its operation as in its assembly and disassembly, which does not require specialized personnel, thus justifying the interest of this anchoring system, guidance and regulation.
La invención consiste en un equipo completo destinado a inspección y reparación de palas de aerogeneradores, compuesto por una plataforma de trabajo a la cual se incorporan los elementos necesarios para realizar el guiado de la misma siguiendo así la trayectoria requerida y dotándola además de los accesorios de regulación que permitan controlar el posicionado de la plataforma.The invention consists of a complete equipment intended for inspection and repair of wind turbine blades, composed of a work platform to which the necessary elements to guide it following thus the required trajectory and providing it with the accessories of regulation to control the positioning of the platform.

La invención ofrece tres configuraciones distintas que se adaptan a distintos modelos de aerogenerador y diversas operaciones de montaje. La primera configuración dispone el anclaje de todos los elementos a incorporar en puntos del interior de la góndola o nacelle, la segunda emplea sólo puntos exteriores y finalmente se describirá la tercera configuración para la cual se emplean puntos exteriores e interiores. En todas ellas partimos de la plataforma de trabajo configurada de manera general como una estructura metálica con una geometría adecuada a la forma específica de las palas del aerogenerador y dotada de un estribo o pieza de sujeción sobre la cual se incorpora un motor de elevación.The invention offers three configurations different that adapt to different wind turbine models and Various assembly operations. The first configuration provides the anchor of all the elements to be incorporated in interior points of the gondola or nacelle, the second uses only external points and finally the third configuration will be described for which They use exterior and interior points. In all of them we start from the work platform generally configured as a metal structure with a geometry appropriate to the specific shape of the wind turbine blades and equipped with a stirrup or piece of clamping on which a lifting motor is incorporated.
A continuación se pasa a describir de manera muy breve una serie de dibujos que ayudan a comprender mejor la invención y que se relacionan expresamente con unas realizaciones de dicha invención que se presentan como ejemplos ilustrativos y no limitativos de ésta.Then it goes on to describe very brief a series of drawings that help to better understand the invention and that expressly relate to embodiments of said invention presented as illustrative examples and not Limitations of this one.

El conjunto de cables de tracción (1) y seguridad requeridos para la elevación de la plataforma (4) suspendida empleada se anclan a puntos estables (6.1) y firmes del interior de la góndola o nacelle como por ejemplo orejetas del propio chasis o argollas de sujeción dispuestas en los equipos de generación, siguiendo las especificaciones dadas en cada caso particular por el fabricante del aerogenerador. Este cableado de tracción (1) se incorpora al motor de elevación para permitir el ascenso/descenso vertical de la plataforma (4). Para poder operar siguiendo la inclinación respecto a la vertical de la pala, derivada como ya se ha comentado de la fijación de los frenos mecánicos, se anclará uno o más cables de guiado (2) en los puntos interiores (6.2) de la góndola ya comentados y que no estén en uso. Los cables de guiado (2) se tienden hacia el suelo donde serán fijados a un punto de anclaje/contrapeso que puede ser por ejemplo el propio vehículo para transporte de los equipos o cualquier otro dispositivo de fijación al terreno (tacos para anclaje mecánico, químico...). El amarre se realizará mediante un dispositivo tensor, no representado, que nos permitirá proporcionar a las guías la tensión de trabajo adecuada. El punto de salida de la góndola del cableado, tanto de tracción (1) como de guiado (2) será el alojamiento dispuesto entre la góndola y el cono protector del rotor. Las guías tensas, siguiendo la trayectoria de la pala, se unen a la plataforma mediante la fijación en la misma de elementos de anclaje dotados de roldadas o mediante la instalación de poleas. Con estos elementos la plataforma de trabajo puede realizar la trayectoria de ascenso/descenso siguiendo la inclinación de la pala. Para aumentar la versatilidad del sistema y permitir acciones de aproximación y regulación que permitan compensar especialmente las acciones del viento se incorpora un elemento intermedio en la sujeción de las guías; en lugar de hacer discurrir el cableado guía directamente por las roldadas incorporadas a la plataforma, se dispondrán las mismas en elementos regulables como por ejemplo cabrestantes u otros dispositivos que ofrezcan longitud variable y regulable por el operador de la plataforma. De este modo se puede controlar la separación de la plataforma respecto a cada una de las guías instaladas.The set of traction cables (1) and safety required for platform lift (4) suspended employees are anchored to stable points (6.1) and firm of the inside the gondola or nacelle such as lugs own chassis or clamping rings arranged in the equipment generation, following the specifications given in each case particular by the manufacturer of the wind turbine. This wiring of traction (1) is incorporated into the lifting motor to allow vertical rise / fall of the platform (4). To be able to operate following the inclination with respect to the vertical of the blade, derived As already mentioned about the fixing of the mechanical brakes, anchor one or more guide wires (2) at the interior points (6.2) of the gondola already commented and not in use. The cables of guidance (2) tend towards the ground where they will be fixed to a anchor / counterweight point which can be for example one's own vehicle for transporting equipment or any other device of fixation to the ground (tacos for mechanical, chemical anchorage ...). He mooring will be carried out by means of a tensioning device, not shown, which will allow us to provide guides with the working tension adequate. The exit point of the wiring gondola, both of traction (1) as guide (2) will be the accommodation arranged between the gondola and the protective cone of the rotor. Strained guides, following the trajectory of the shovel, they join the platform by fixing it with anchoring elements equipped with Rolled or by installing pulleys. With these elements the work platform can realize the trajectory of ascent / descent following the inclination of the blade. To increase the versatility of the system and allow approach actions and regulation to compensate especially the actions of the wind is incorporated an intermediate element in the clamping of the guides; instead of running the guide wiring directly through the rolls incorporated to the platform, the same will be arranged in adjustable elements such as winches or others devices that offer variable length and adjustable by the platform operator. In this way you can control the platform separation with respect to each of the guides installed.
