Description

Dispositivo para abatimiento de torres en estructuras móviles.Device for tower abatement in mobile structures

Objeto de la invenciónObject of the invention

La presente invención se refiere a un dispositivo que ha sido especialmente concebido para facilitar el abatimiento de torres, tanto en su elevación como en su descenso, en estructuras móviles, como por ejemplo en estructuras para servicios relacionados con el espectáculo.The present invention relates to a device which has been specially designed to facilitate dejection of towers, both in its elevation and in its descent, in mobile structures, such as service structures related to the show.

El objeto de la invención es conseguir el abatimiento de dichas torres de una manera rápida, fácil y sencilla, minimizando de forma muy considerable los riesgos de accidentes durante su manipulación.The object of the invention is to achieve the dejection of these towers in a fast, easy and simple, greatly minimizing the risks of accidents during handling.

Antecedentes de la invenciónBackground of the invention

En eventos al aire libre se utilizan habitualmente estructuras, que se montan temporalmente sobre el terreno, y en dichas estructuras participan torres de considerable altura, por las que generalmente suelen ser deslizantes respectivos carros capaces de alcanzar la cota determinada por la altura de la correspondiente torre, de manera que estos carros pueden ser portadores de medios de iluminación del evento, de Cámaras para filmación del mismo, etc.In outdoor events they are used usually structures, which are temporarily mounted on the land, and in these structures participate towers of considerable height, for which they are usually respective slides cars capable of reaching the level determined by the height of the corresponding tower, so that these cars can be carriers of event lighting media, from Cameras to filming of it, etc.

Estos espectáculos suelen ser de escasa repetitividad, en muchas ocasiones de una sola actuación en el determinado lugar, de manera que el abatimiento de las torres constituye una tarea constante, prácticamente diaria.These shows are usually scarce repetitiveness, on many occasions of a single performance in the certain place, so that the dejection of the towers It is a constant, almost daily task.

En la actualidad y para llevar a cabo estas maniobras de manipulación de las torres, se utiliza fundamentalmente mano de obra, habitualmente con el concurso de diez personas que tiran de la torre por ambos lados de la misma, para que ésta pase de la posición horizontal a la vertical y viceversa, solución poco fiable y segura, que evidentemente necesita además de una considerable participación de mano de obra.Currently and to carry out these tower manipulation maneuvers, it is used primarily labor, usually with the contest of ten people pulling the tower on both sides of it, so that it goes from horizontal to vertical position and vice versa, unreliable and secure solution, which obviously it also needs considerable participation from work.

En ocasiones las torres también se abaten con un sistema trapezoidal que utiliza el propio motor de la torre, el de movilización del citado carro, para pasar de la posición vertical a la horizontal, sistema que supone unas condiciones de seguridad inaceptables.Sometimes the towers also get down with a trapezoidal system that uses the tower's own engine, that of mobilization of said car, to move from the vertical position to the horizontal, system that involves safety conditions unacceptable

Igualmente inseguro es el sistema de abatimiento basado en traccionar de la torre con una cuerda o soga, traccionada manualmente con un torito, ya que es frecuente que dicha cuerda se deslice e incluso se rompa.Equally insecure is the dejection system based on pulling the tower with a rope or rope, pulled manually with a bull, since it is frequent that said rope is slide and even break.

También se utilizan sistemas de grúa para manipular las torres, anclándolas mediante un gancho en su extremidad superior, pero evidentemente ésta solución resulta muy costosa por la inversión o el alquiler de dicha grúa.Crane systems are also used to manipulate the towers, anchoring them with a hook on their upper limb, but obviously this solution is very expensive for the investment or rent of said crane.

Descripción de la invenciónDescription of the invention

El dispositivo para abatimiento de torres que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, constituyendo una estructuración simple y segura, de fácil manipulación y plenamente eficaz.The device for tower abatement that the proposed invention resolves in a fully satisfactory manner the problem described above, constituting a simple and safe structuring, easy handling and fully effective.

Para ello y de forma más concreta dicho dispositivo consiste en una pieza abatidora, a modo de biela, que relaciona articuladamente la estructura general y básica sobre la que está anclada la base de la torre, con la parte móvil de dicha torre, es decir con la parte mayoritaria de la misma que se une con carácter abatible a la citada base, de manera que éstos elementos, el conjunto base de la torre-estructura general, parte móvil de la torre y biela configuran un cuadrilátero deformable que permite a la parte móvil de la torre adoptar dos posiciones extremas; una horizontal o de abatimiento, y otra vertical o de uso.To do this and more specifically said device consists of a grinding piece, as a connecting rod, which articulate the general and basic structure on the that the base of the tower is anchored, with the mobile part of said tower, that is to say with the majority of it that joins with character foldable to that base, so that these elements, the base set of the general tower-structure, moving part of the tower and connecting rod set up a quadrilateral deformable that allows the mobile part of the tower to adopt two extreme positions; one horizontal or dejection, and another vertical or use.

Para el cambio de una a otra posición de la citada parte móvil de la torre, entre la zona media de la mencionada biela y la estructura general se establece un pistón cuya situación de máxima retracción se corresponde con la posición horizontal o abatida de la parte móvil de la torre, mientras que su situación de máxima extensión se corresponde a su vez con la disposición vertical para la parte móvil de la torre.For the change from one to another position of the cited mobile part of the tower, between the middle area of the mentioned connecting rod and the general structure is established a piston whose maximum retraction situation corresponds to the position horizontal or dejected of the mobile part of the tower, while its situation of maximum extension corresponds in turn with the Vertical layout for the mobile part of the tower.

Preferentemente el citado pistón será hidráulico, contando el dispositivo con una bomba de presión accionada por un motor eléctrico con la tensión habitual de red, es decir con una tensión nominal de 220 V en corriente alterna, pero obviamente existe la posibilidad de que el citado pistón sea sustituido por un sistema de extensión "husillo-tuerca", en el que el citado husillo será directamente accionado por un motor eléctrico, sin que prácticamente exista limitación alguna en cuanto a las posibilidades de selección para el mecanismo encargado de hacer bascular la biela o pieza abatidora.Preferably said piston will be hydraulic, counting the device with a pressure pump driven by a electric motor with the usual mains voltage, that is with a nominal voltage of 220 V in alternating current, but obviously there is a possibility that said piston is replaced by a spindle-nut extension system, in the that said spindle will be directly driven by a motor electrical, with virtually no limitation as far as to the selection possibilities for the mechanism in charge of swing the connecting rod or piece.

Realización preferente de la invenciónPreferred Embodiment of the Invention

En las figuras reseñadas se ha referenciado con (1) la estructura general móvil, es decir desmontable y transportable, que participa en montajes para espectáculos al aire libre y similares, que por ejemplo define un marco rectangular, de acuerdo con la representación de la figura 4, en uno o en cada uno de cuyos vértices se establece la base fija (2) de una torre, fija a la estructura (1), base (2) que sobresale en altura con respecto a la estructura (1) y que a través de un eje de abisagramiento (3) recibe a la parte móvil o abatible (4) de la torre, la cual se remata habitualmente por su extremidad superior y libre en una cruceta (5), con poleas o coronas dentadas para transmisión de movimiento a correas o cadenas que, accionadas por un motor eléctrico inferior, permiten la elevación y descenso de un carro utilizable en funciones de plataforma do trabajo o de soporte para diferentes elementos que van a ser instalados a la altura definida por la torre.In the figures outlined it has been referenced with (1) the general mobile structure, that is detachable and transportable, which participates in assemblies for outdoor shows free and similar, which for example defines a rectangular frame, of according to the representation of figure 4, in one or in each of whose vertices the fixed base (2) of a tower is established, fixed to the structure (1), base (2) that stands out in height with respect to the structure (1) and that through a hinge shaft (3) receive the mobile or collapsible part (4) of the tower, which usually topped by its upper and free limb in a crosshead (5), with pulleys or toothed crowns for transmission of movement to belts or chains that, driven by an engine Electric bottom, allow the lifting and lowering of a car Usable in work platform or support functions for different elements that will be installed at the defined height by the tower

Pues bien, a partir de ésta estructuración básica y convencional, y de acuerdo ya con la invención, entre la estructural general (1) y la parte móvil (4) de la torre se establece una biela o pieza abatidora (6), unida articuladamente a las dos piezas las que relaciona y que con estas últimas y como se observa en las figuras 1 a 3 configura un paralelogramo deformable en el que dos de sus lados, los correspondientes o definidos por la estructura general (1) y la base fija (2) de la torre, se mantienen inmóviles, mientras que los otros dos son susceptibles de cambiar de posición, concretamente de variar su inclinación desde la posición mostrada en la figura 1 a la posición mostrada en la figura 3, respectivamente correspondientes a la situación de abatimiento u horizontalidad de la parte móvil (4) de la torre y la de verticalidad de la misma.Well, from this basic structuring and conventional, and according to the invention, between the general structural (1) and the mobile part (4) of the tower is establishes a connecting rod or piece (6), jointly connected to the two pieces which relates and that with the latter and how to see in figures 1 to 3 configure a deformable parallelogram in which two of its sides, corresponding or defined by the general structure (1) and the fixed base (2) of the tower, are maintained motionless, while the other two are likely to change position, specifically to vary its inclination from the position shown in figure 1 to the position shown in the figure 3, respectively corresponding to the situation of dejection or horizontality of the mobile part (4) of the tower and the of verticality of it.

Para conseguir este cambio de posición en la parte móvil (4) de la torre, de una manera cómoda, segura y sencilla, entre la zona media de la biela (6) y la estructura general (1) se establece un pistón (7) que cuando se encuentra en situación de máxima retracción determina para la biela (6) una posición de máxima inclinación, y consecuentemente para la parte móvil (4) de la torre una posición de horizontalidad, la mostrada en la figura (1), mientras que a medida que se extiende provoca la basculación ascendente de la biela (6), con una paralela basculación también ascendente de la parte móvil (4) de la torre, tal como muestra la figura 2, hasta una situación límite, que normalmente deberá corresponderse con la máxima extensión de dicho pistón (7), en la que la inclinación de la biela (6) ha sobrepasado la vertical y se muestra de signo contrario, en la que la parte móvil (4) de la torre adopta una disposición perfectamente vertical, como prolongación de su base (2) y tal como muestra la figura 3.To get this change of position in the moving part (4) of the tower, in a comfortable, safe and simple, between the middle of the connecting rod (6) and the structure general (1) a piston (7) is established which when it is in maximum retraction situation determines for the connecting rod (6) a position of maximum inclination, and consequently for the part mobile (4) of the tower a horizontal position, the one shown in figure (1), while as it spreads it causes the upward tilt of the connecting rod (6), with a parallel also upward tilt of the mobile part (4) of the tower, as shown in figure 2, up to a limit situation, which normally it must correspond to the maximum extent of said piston (7), in which the inclination of the connecting rod (6) has exceeded the vertical and shown opposite sign, in which the part Tower mobile (4) adopts a perfectly arranged vertical, as an extension of its base (2) and as shown by the figure 3.

Solo resta señalar por último que, como es evidente, la biela o pieza abatidora (6) y el pistón (7) deben ser eliminados mientras la estructura móvil se encuentra en situación de uso o de transporte, a cuyo efecto la estructura general y la torre deben incorporara medios de acoplamiento/desacoplamiento rápido tanto para la biela como para el pistón, lo mismo que sucede con estos elementos entre sí, y de manera también que un único dispositivo resulta utilizable en las múltiples torres que pueden participar en una determinada estructura.It only remains to note that, as is Obviously, the connecting rod (6) and the piston (7) must be removed while the mobile structure is in situation for use or transport, for which purpose the general structure and the tower must incorporate coupling / decoupling means fast for both the connecting rod and the piston, the same thing that happens with these elements with each other, and so that a single device is usable in the multiple towers that can Participate in a certain structure.
