Description
DESCRIPCIÓN DESCRIPTION
Dispositivo trepador para desplazamiento de grandes estructuras móviles. Climbing device for moving large mobile structures.
Objeto de la invención Object of the invention
La presente invención, como su propio título indica, se refiere a un dispositivo para desplazar grandes estructuras móviles o rotativas, cubiertas de estadios deportivos, compuertas de telescopios astronómicos, estructuras de aerogeneradores, escenarios para espectáculos, así como para carga y/o descarga de buques mercantes, etc. The present invention, as its own title indicates, refers to a device for moving large mobile or rotating structures, sports stadium decks, astronomical telescope gates, wind turbine structures, stages for shows, as well as for loading and / or unloading of merchant ships, etc.
Antecedentes de la invención Background of the invention
Los sistemas de accionamiento de las grandes estructuras móviles han mostrado poca evolución desde el inicio de la construcción de grandes estadios retráctil. Estos sistemas suelen estar basados en soluciones disponibles en diferentes aplicaciones industriales, por ejemplo en los grandes equipos destinados a mover maquinaria, grúas, etc. Se trata de elementos disponibles en el mercado, que son voluminosos e ineficientes en términos de masa y volumen, y no lo suficientemente fiables cuando se aplica a grandes estructuras flexibles. Uno de los mecanismos que más se ha empleado hasta la fecha consiste en un acoplamiento entre un piñón móvil y una cremallera fija. Si estudiamos el movimiento de este mecanismo observamos que sólo uno o dos dientes del piñón contribuyen eficazmente en el accionamiento de la estructura, con lo cual si la potencia transmitida en el movimiento es elevada puede provocar la rotura de alguno de los elementos del acoplamiento; por otro lado la fiabilidad y precisión son bastante escasas.
Los mecanismos de oruga ofrecen un mayor número de dientes en contacto y por tanto resultan más compactos, rígidos y robustos. Mecanismos de este tipo se emplean por ejemplo para desplazar una cadena de arrastre que apoya directamente sobre el suelo (propia este tipo de tracción en vehículos pesados). The drive systems of large mobile structures have shown little evolution since the beginning of the construction of large retractable stadiums. These systems are usually based on solutions available in different industrial applications, for example in large equipment intended to move machinery, cranes, etc. These are commercially available items, which are bulky and inefficient in terms of mass and volume, and not reliable enough when applied to large flexible structures. One of the most widely used mechanisms to date consists of a coupling between a mobile pinion and a fixed rack. If we study the movement of this mechanism we observe that only one or two teeth of the pinion contribute effectively in the actuation of the structure, whereby if the power transmitted in the movement is high it can cause the breakage of some of the elements of the coupling; On the other hand, reliability and precision are quite scarce. The caterpillar mechanisms offer a greater number of teeth in contact and therefore are more compact, rigid and robust. Mechanisms of this type are used for example to move a drag chain that rests directly on the ground (this type of traction in heavy vehicles itself).
Descripción de la invención Description of the invention
El mecanismo de la presente invención es similar a un mecanismo de tipo oruga, en cuanto que consiste en una cremallera sobre la que se desplazan varios peines, que se disponen longitudinalmente con respecto a dicha cremallera y se accionan por medio de un mecanismo excéntrico tipo cigüeñal, de forma que cada peine va describiendo un movimiento circular encima de la cremallera, acoplando en ella al tiempo que la empuja en sentido de avance y separándose de ella para retroceder en contra al sentido de avance de la misma, para volver a acoplarse en una posición más retrasada y comenzar con el empuje de nuevo, una vez que por su movimiento circular desciende y acopla de nuevo en ella. El movimiento es más preciso que un mecanismo convencional puesto que el paso de diente de cada peine puede ser sensiblemente menor que cualquier piñón circular que se pueda desarrollar para la misma potencia de arrastre. The mechanism of the present invention is similar to a caterpillar type mechanism, in that it consists of a rack on which several combs are moved, which are arranged longitudinally with respect to said rack and are actuated by means of a crankshaft type eccentric mechanism. , so that each comb is describing a circular movement on top of the zipper, engaging in it while pushing it in the direction of advance and separating from it to retract against the direction of advance of it, to re-engage in a position more delayed and start with the thrust again, once by its circular motion it descends and engages again in it. The movement is more precise than a conventional mechanism since the tooth pitch of each comb can be significantly smaller than any circular pinion that can be developed for the same drag power.
Como quiera que el número de peines es relativamente elevado, como mínimo se colocan entre 3 y 9 peines, preferentemente 6, en todo momento al menos uno de estos peines está engranado en la cremallera realizando así un desplazamiento muy preciso y, aunque la fuerza de tracción sea grande, la tensión de cada diente es sensiblemente menor que un mecanismo convencional piñón-cremallera, puesto que la fuerza total se divide entre el número de dientes. Además, el mecanismo está pensado para que al menos todos los dientes de un peine (y en ocasiones de dos) estén en contacto con la cremallera en un momento dado, con lo cual el número de dientes en contacto siempre es alto, a diferencia de los mecanismos de tipo piñón-cremallera en el que el número medio de dientes
es contacto es siempre menor de dos; por ello, se minimiza el esfuerzo en cada diente, aún con una fuerza de arrastre sensiblemente menor, por lo que los dientes pueden ser mucho más pequeños y se puede conseguir un sistema de desplazamiento de mayor precisión y fiabilidad. Since the number of combs is relatively high, at least 3 to 9 combs are placed, preferably 6, at least one of these combs is at all times engaged in the rack, thus carrying out a very precise movement and, although the force of traction is large, the tension of each tooth is significantly less than a conventional pinion-rack mechanism, since the total force is divided by the number of teeth. In addition, the mechanism is designed so that at least all the teeth of a comb (and sometimes two) are in contact with the zipper at any given time, with which the number of teeth in contact is always high, unlike the pinion-rack type mechanisms in which the average number of teeth It's contact is always less than two; therefore, the effort in each tooth is minimized, even with a significantly lower drag force, so that the teeth can be much smaller and a more precise and reliable displacement system can be achieved.
Así pues, los principales beneficios del mecanismo en comparación con los sistemas de transmisión tradicional de las grandes estructuras móviles es que es más eficiente y compacto si tomamos en consideración la velocidad requeridas para una aplicación determinada. Proporciona además una conexión muy fuerte entre la parte fija (de referencia) de la estructura y la estructura móvil, asegurando una gran precisión de la posición requerida y un funcionamiento suave. Thus, the main benefits of the mechanism compared to traditional transmission systems of large mobile structures is that it is more efficient and compact if we consider the speed required for a given application. It also provides a very strong connection between the fixed (reference) part of the structure and the mobile structure, ensuring high accuracy of the required position and smooth operation.
Para efectuar el movimiento circular de los peines, de avance acoplado en la cremallera y retroceso en vacío, éstos se montan en dos cigüeñales cuyas excéntricas determinan al girar la posición de cada peine. Ambos cigüeñales son iguales y están sincronizados o montados en igual posición para que el movimiento de los dos extremos del peine sea uniforme y el cuerpo del mismo permanezca en posición horizontal encima de la cremallera en todo momento. El conjunto de peines con sus cigüeñales y el resto de elementos del dispositivo se monta en un bastidor que presenta dos placas de cierre, que incorporan los cojinetes para los cigüeñales y los rodamientos para una serie de rodillos de apoyo del mecanismo en la cremallera, en los que recae la labor de soportar el peso del sistema, de forma que los peines de arrastra no sufren en este sentido ya que ellos no soportan ningún peso. El hecho de que el dispositivo se apoye en un conjunto de rodillos permite que la fricción de deslizamiento no se produzca en el punto de contacto del mecanismo de accionamiento, lo que aumenta la eficiencia de mecanismo y reduce el desgaste de los peines y rodillos, el único punto de fricción se produce en el contacto entre los rodillos y pasadores de la cremallera, donde la distribución de la presión es más uniforme. En este sentido, el funcionamiento del dispositivo es más similar a un sistema piñón-cadena que a un sistema cremallera.
En los extremos, dicho bastidor incorpora unos muñones montados en unas rótulas esféricas, sobre los que se apoya la estructura móvil, transmitiendo el peso al mecanismo y éste a través las ruedas de apoyo en la estructura fija, constituida en este caso por una cremallera sobre la que se desplaza la carga. El bastidor del trepador monta también otro conjunto de ruedas verticales que evitan que se eleve en cualquier momento; estas ruedas apoyan en otra pista instalada en frente, soportando las reacciones causadas por el ángulo de presión del contacto del peine. To effect the circular movement of the combs, of advance coupled in the zipper and reverse in empty, these are mounted in two crankshafts whose eccentric ones determine when turning the position of each comb. Both crankshafts are the same and are synchronized or mounted in the same position so that the movement of the two ends of the comb is uniform and the body of the comb remains horizontally above the rack at all times. The set of combs with their crankshafts and the rest of the elements of the device is mounted on a frame that has two closing plates, which incorporate the bearings for the crankshafts and the bearings for a series of rollers supporting the mechanism in the rack, in those who relapse the work of supporting the weight of the system, so that the drag combs do not suffer in this sense since they do not support any weight. The fact that the device is supported by a set of rollers allows sliding friction not to occur at the point of contact of the drive mechanism, which increases the efficiency of the mechanism and reduces the wear of the combs and rollers, the Single point of friction occurs at the contact between the rollers and rack pins, where the pressure distribution is more uniform. In this sense, the operation of the device is more similar to a pinion-chain system than to a rack system. At the ends, said frame incorporates stumps mounted on spherical ball joints, on which the mobile structure rests, transmitting the weight to the mechanism and this through the support wheels in the fixed structure, constituted in this case by a rack on the one that moves the load. The climber frame also mounts another set of vertical wheels that prevent it from rising at any time; These wheels rest on another track installed in front, supporting the reactions caused by the pressure angle of the comb contact.

Realización preferente de la invención Preferred Embodiment of the Invention
Como se puede observar en las figuras referenciadas el dispositivo para desplazamiento de grandes estructuras movibles, se interpone entre la estructura fija, que incorpora una cremallera sobre la que se desplaza la estructura móvil, apoyada en distintos dispositivos de esta índole situados en
diversos puntos convenientemente distribuidos de conformidad con la estructura a mover. As can be seen in the referenced figures, the device for the movement of large movable structures, is interposed between the fixed structure, which incorporates a zipper on which the mobile structure moves, supported by different devices of this nature located in various points conveniently distributed in accordance with the structure to be moved.
Cada dispositivo está accionado por dos servomotores sincronizados (1 ), que mueven sendos cigüeñales (3), que se montan en un bastidor formado por dos placas de cierre (5), en las que se montan los cojinetes y rodamientos en los que giran dichos cigüeñales y diversas ruedas o rodillos (4,6). En los cigüeñales (3) se montan una serie de peines (2) dispuestos paralelos entre sí y con respecto a la cremallera o la línea de avance del dispositivo. Los dientes (8) de los peines (2) están configurados con el paso de la cremallera fija, de forma que son susceptibles de acoplar mecánicamente en ella. Al girar los dos cigüeñales (3), que los atraviesan transversalmente, cada uno de los peines efectúa un movimiento determinado por las respectivas excéntricas que presentan los respectivos cigüeñales en la zona de acoplamiento del peine, las cuales presentan en todo momento la misma disposición para que el peine siempre esté en posición horizontal y efectúe un movimiento de rotación sobre dos ejes laterales, coincidentes con los respectivos cigüeñales, que longitudinalmente se traduce en un movimiento de aproximación y arrastre del dispositivo al apoyarse en la cremallera y seguidamente de alejamiento de la cremallera y retroceso a una posición anterior. Each device is driven by two synchronized servomotors (1), which move two crankshafts (3), which are mounted on a frame formed by two closing plates (5), in which the bearings and bearings on which they rotate are mounted. crankshafts and various wheels or rollers (4,6). On the crankshafts (3) a series of combs (2) are mounted parallel to each other and with respect to the rack or the advance line of the device. The teeth (8) of the combs (2) are configured with the passage of the fixed rack, so that they can be mechanically coupled thereto. By turning the two crankshafts (3), which cross them transversely, each of the combs makes a movement determined by the respective eccentrics presented by the respective crankshafts in the comb coupling area, which at all times have the same arrangement for that the comb is always in a horizontal position and makes a rotation movement on two lateral axes, coinciding with the respective crankshafts, which longitudinally translates into an approach and drag movement of the device when resting on the zipper and then away from the zipper and back to a previous position.
En el ejemplo representado en las figuras el número de peines es de 6, siendo éste el número que se ha encontrado más idóneo para esta solución; no obstante podría diseñarse y construirse un dispositivo con un número de peines comprendido entre 3 y 9. El desfase angular entre las excéntricas que coinciden con cada peine (2), de cada cigüeñal (3), es tal que en todo momento al menos un peine está acoplado en la cremallera empujando de la parte móvil del dispositivo; aunque en ocasiones son dos los peines acoplados en la cremallera sobre la que se desplaza el dispositivo, de forma que el número de dientes que están engranando en ella es elevado.
Como ya se ha indicado, el conjunto de peines (2) y cigüeñales (3) se monta en un bastidor que presenta dos placas de cierre (5) en las que se montan los cojinetes para los dos cigüeñales (3). Entre dichas placas (5), sobre unos rodamientos, se montan dos rodillos o ruedas almenadas (4) a través de las cuales el dispositivo se apoya en la cremallera, de forma que son estos rodillos los que soportan el peso de la estructura móvil y no los peines que únicamente ejercen labores de desplazamiento por lo que sus dientes no se ven sometidos a una tensión elevada. Así mismo entre las placas (5) que configuran el bastidor del dispositivo se montan en los extremos sendos muñones (6), a través de unos rodamientos o rótulas esféricas. La finalidad de estos muñones es la de servir de apoyo para la estructura móvil, la cual transmite su peso en estos puntos al bastidor y éste a través de los ruedas de soporte (4) a la estructura fija a través de la cremallera existente en ella. In the example represented in the figures the number of combs is 6, this being the number that has been found most suitable for this solution; however, a device with a number of combs between 3 and 9 could be designed and constructed. The angular offset between the eccentrics that coincide with each comb (2), of each crankshaft (3), is such that at least one Comb is attached to the zipper by pushing the moving part of the device; although sometimes there are two combs attached to the zipper on which the device moves, so that the number of teeth that are engaging in it is high. As already indicated, the set of combs (2) and crankshafts (3) is mounted on a frame that has two closing plates (5) on which the bearings for the two crankshafts (3) are mounted. Between said plates (5), on some bearings, two rollers or crenellated wheels (4) are mounted through which the device is supported by the rack, so that it is these rollers that support the weight of the mobile structure and not the combs that only exercise displacement so that their teeth are not subjected to high tension. Also between the plates (5) that make up the frame of the device are mounted on the ends of each stump (6), through spherical bearings or spherical plain bearings. The purpose of these stumps is to serve as support for the mobile structure, which transmits its weight at these points to the frame and this through the support wheels (4) to the fixed structure through the existing rack in it .
Según se aprecia en las figuras el dispositivo se completa con sendos cojinetes en los que se montan una serie de ruedas verticales (7) que apoyan en una pista situada en frente. La finalidad de estas ruedas es evitar que el dispositivo se pueda elevar por cualquier causa. As can be seen in the figures, the device is completed with two bearings in which a series of vertical wheels (7) are mounted, which rest on a track located in front. The purpose of these wheels is to prevent the device from being lifted for any reason.
