Description

Máquina limpia rejas por brazo oscilante para presas hidráulicas. Machine clean bars by swing arm for hydraulic dams.
La presente memoria descriptiva se refiere, como su título indica, a una máquina limpia rejas por brazo oscilante para presas hidráulicas del tipo de las empleadas para limpiar la suciedad que se deposita en las rejas de las presas hidráulicas, principalmente cuando el caudal de agua es destinado a centrales eléctricas.The present specification refers, as its title indicates, to a clean machine bars by swing arm for hydraulic dams of the type used to clean the dirt that is deposited in the bars of the hydraulic dams, mainly when the water flow is intended for power plants.
Los mecanismos conocidos generalmente, consisten en una máquina montada sobre un bastidor el cual dispone de un sistema de rodadura, para desplazar a la máquina que comporta a lo largo de la presa, mediante unos raíles o guías fijados al suelo. Este tipo de máquinas incorporan una cuchara con un sistema de apertura por cable que se desliza por la reja bajando abierta y subiendo cerrada.The generally known mechanisms consist of a machine mounted on a frame which has a rolling system, to move the machine along the dam, by means of rails or guides fixed to the ground. This type of machines incorporates a spoon with a cable opening system that slides down the gate, going down and up.
También suelen incorporar las máquinas descritas anteriormente a una pluma o brazo grύa, provisto de articulaciones fijadas a una base orientable y disponiendo en el extremo de aprensión de unas pinzas capaces de agarrar a los cuerpos voluminosos y grandes troncos que la cuchara o pala no ha sido capaz de extraer de la superficie del agua; el manejo de estas máquinas lo realiza un operador que en todo momento deberá estar dispuesto a mantener la limpieza adecuada del agua que como nos hemos referido con anterioridad, ésta es destinada para mover las turbinas de centrales eléctricas.They also usually incorporate the machines described above to a pen or gray arm, provided with joints fixed to an adjustable base and having at the end of apprehension some tweezers capable of grasping bulky bodies and large trunks that the spoon or shovel has not been able to extract from the surface of the water; The operation of these machines is carried out by an operator who at all times must be willing to maintain the proper cleaning of the water that, as we have previously mentioned, is intended to move the turbines of power plants.
otro mecanismo conocido consiste en un sistema a modo de peine fijo que cubre toda la anchura de la presa subiendo y bajando por medio de dos cremalleras que son accionadas por medio de un motor eléctrico exterior. Otro sistema conocido consiste en que la máquina conlleva a un rastrillo, pala o similar el cual está fijado al extremo inferior de un brazo y que actúa por elevación de todo el mencionado brazo.Another known mechanism consists of a fixed comb system that covers the entire width of the dam by rising and falling by means of two zippers that are driven by an external electric motor. Another known system is that the machine leads to a rake, shovel or the like which is fixed to the lower end of an arm and that acts by lifting the entire said arm.
Algunos de los mecanismos o máquinas descritos anteriormente incorporan a un transportador que retira la suciedad extraída, estando situado este transportador en la parte inferior de la máquina y generalmente por el suelo o muy cercano a éste siendo limitado el paso de la suciedad hacia el transportador, por un hueco a modo de ventana; cuando no incorporan transportador en el sistema de limpieza de las rejas, la cuchara deposita la suciedad sobre el piso teniéndose que retirar ésta manualmente.Some of the mechanisms or machines described above incorporate a conveyor that removes the dirt removed, this conveyor being located at the bottom of the machine and generally on the ground or very close to it being limited the passage of dirt to the conveyor, by a hole as a window; when they do not incorporate conveyor in the cleaning system of the bars, the spoon deposits the dirt on the floor having to remove it manually.
Los mecanismos que incorporan a una cuchara que se desliza por la reja, presentan el inconveniente de que por bajar pegados a la citada reja, no pueden salvar troncos o cuerpos flotantes de grandes dimensiones y en el supuesto de que en el movimiento de ascensión consiguiera atrapar a alguno de éstos, no podría evacuarlo por estar limitado el paso para la extracción de la suciedad, a través de un hueco semejante a una ventana.The mechanisms that incorporate a spoon that slides through the fence, have the disadvantage that by lowering them glued to the aforementioned fence, they cannot save large logs or floating bodies and in the assumption that in the ascending movement they managed to catch to any of these, I could not evacuate it because the passage for dirt extraction is limited, through a window-like hole.
El sistema de limpieza de las rejas por un peine fijo tiene el inconveniente de que al deslizarse pegado a la reja no puede recoger objetos muy voluminosos así como troncos de considerables dimensiones, teniendo además el inconveniente de que su uso está limitado a presas de reducidas dimensiones en cuanto a anchura y altura se refiere.The cleaning system of the bars by a fixed comb has the disadvantage that when sliding attached to the fence it cannot collect very bulky objects as well as trunks of considerable dimensions, also having the disadvantage that its use is limited to small-sized dams as far as width and height is concerned.
La máquinas que integran a un rastrillo o pala fijado en el extremo de un brazo que se eleva en su totalidad para poder extraer la suciedad acumulada en la reja, presentan el inconveniente de que para presas que tengan una profundidad considerable el brazo resulta excesivamente largo a la par que si extrae algún cuerpo de grandes dimensiones o troncos y ramajes voluminosos, estos materiales no pueden ser evacuados por tener limitado el paso por un hueco semejante a una ventana similar a otras máquinas.The machines that integrate a rake or shovel fixed at the end of an arm that rises in its entirety to be able to extract the dirt accumulated in the grating, they have the disadvantage that for dams that have a considerable depth the arm is excessively long at the same time that if you remove any large body or bulky trunks and branches, these materials cannot be evacuated by having limited passage through a hole similar to a window similar to other machines.
Para solventar estos inconvenientes se ha ideado el limpia rejas por brazo oscilante para presas hidráulicas objeto de la presente invención en donde se incorpora un brazo oscilante sobre un punto de giro por el cual discurren unas guías capaces de permitir el deslizamiento de un carro provisto de unas rodaduras que conlleva a un soporte en el que está fijada la pala o rastrillo capaz de extraer la suciedad atrapada por la reja tanto del fondo como de la superficie del agua aunque sean cuerpos, troncos o ramajes de considerables dimensiones, pues no existe ningún paso obligado o ventana entre la pala al descargar y el tranportador que retirará la suciedad extraída.In order to solve these inconveniences, the clean bars by swing arm for hydraulic dams object of the present invention have been devised where a swing arm is incorporated on a turning point through which guides run capable of allowing the sliding of a carriage provided with some Breaks that lead to a support in which the shovel or rake is fixed capable of extracting the dirt trapped by the grating of both the bottom and the surface of the water even if they are bodies, trunks or branches of considerable dimensions, since there is no obligatory step or window between the shovel when unloading and the transporter that will remove the dirt removed.
La pala o rastrillo que es solidaria al carro de rodadura se desliza por el brazo oscilante, merced a una cadena de arrastre que es accionada por un motor hidráulico.The blade or rake that is integral to the carriage slides along the swing arm, thanks to a drag chain that is driven by a hydraulic motor.
La máquina limpia rejas por brazo oscilante para presas hidráulicas que nos ocupa tiene la ventaja sobre todos los sistemas conocidos de que en el movimiento de descenso de la cuchara, el brazo que la guía al ser oscilante se separa de la reja mediante la acción de un cilindro hidráulico lo suficiente, como para que en su fase de acercamiento hacia el fondo de la reja, poder cargar la suciedad depositada en dicho fondo. __ι _The machine cleans bars by oscillating arm for hydraulic dams that occupies us has the advantage over all known systems that in the movement of lowering the bucket, the arm that guides the oscillating being is separated from the fence by the action of a Enough hydraulic cylinder, so that in its approach phase towards the bottom of the fence, it is possible to load the dirt deposited in said bottom. __ι _
Otra ventaja que se aporta en el presente invento es que la estructura de la máquina evita la formación de un paso obligado hacia el transportador para cuando la cuchara extrae la suciedad que puede estar compuesta de porciones pequeñas así como de grandes cuerpos y troncos de considerables dimensiones.Another advantage that is provided in the present invention is that the structure of the machine prevents the formation of a forced passage towards the conveyor when the bucket removes dirt that can be composed of small portions as well as large bodies and trunks of considerable dimensions .
otra ventaja económica aportada en este invento, supone la eliminación del brazo grúa complementario que otros sistemas de limpieza de rejas tienen que instalar para poder extraer a los ya referidos grandes cuerpos y troncos consi erables.Another economic advantage provided in this invention is the elimination of the complementary crane arm that other fence cleaning systems have to install in order to extract the aforementioned large bodies and substantial logs.
otra ventaja referente a este invento consiste en que el gobierno de los mecanismos mediante una central hidráulica puede hacerse tanto manual como automáticamente con lo cual el operario del sistema puede compartir las tareas de limpieza con diversas misiones.Another advantage concerning this invention is that the governance of the mechanisms by means of a hydraulic power plant can be done both manually and automatically, with which the system operator can share the cleaning tasks with various missions.
Otra ventaja de la máquina limpia rejas que presentamos consiste en que es capaz de limpiar cualquier forma de presa y cualquier profundidad ya que su brazo oscilante permite el acceso a cualquier punto de la reja aunque ésta tenga forma irregular.Another advantage of the machine that lattices clean is that it is able to clean any form of prey and any depth since its swing arm allows access to any point of the fence even if it is irregularly shaped.
