Description

Dispositivo de empalme de tramos de bandeja del tipo escalera para soportar cables.Device for splicing tray sections ladder type to support cables.

Campo de la invenciónField of the Invention

La presente invención se refiere a un dispositivo de empalme de tramos de bandeja del tipo escalera de los que se emplean para soportar cables eléctricos. Dichos tramos de bandeja del tipo escalera son los constituidos por dos largueros o perfiles laterales y varios travesaños dispuestos entre los largueros y distanciados entre sí en toda su longitud.The present invention relates to a splicing device of ladder type trays those used to support electrical cables. These sections of tray of the ladder type are those constituted by two stringers or side profiles and several crossbars arranged between stringers and spaced apart from each other throughout its length.

Antecedentes de la invenciónBackground of the invention

Las instalaciones con bandejas del tipo escalera para soportar cables están constituidas por varios tramos de estas bandejas unidos entre sí.Installations with ladder type trays to support cables are constituted by several sections of these trays joined together.

Habitualmente se utilizan dos placas de unión y varios tornillos y tuercas (cuyo número podía ser de 8 ó más) para ejecutar la unión entre dos tramos, lo cual resulta lento y costos, a lo que había que sumar el coste adicional de dichas piezas. También se ha empleado la unión por medio de mordazas que se pueden fijar a los extremos de los largueros mediante pernos o remaches.Usually two joining plates are used and several screws and nuts (whose number could be 8 or more) to execute the union between two sections, which is slow and costs, To which we had to add the additional cost of these pieces. The union has also been used by means of jaws that can be fix to the ends of the stringers by bolts or rivets

El modelo de utilidad español 1041681, por "Disposición para empalmes de bandejas portacables del tipo escalera", propone una configuración de bandeja portacables en la que cada uno de los perfiles que forma los laterales de la estructura dispone en uno de sus extremos un dispositivo de enlace con el extremo opuesto del perfil siguiente, presentando el conjunto simetría binaria con respecto a un eje central perpendicular al plano de la estructura, permitiendo la fijación de cada par de tramos de estructura mediante la unión de los elementos macho y hembra del extremo de uno de los tramos con los correspondientes hembra y macho del otro. Sobre los extremos de los tramos hay varios orificios de unión-fijación complementarios que permiten asegurar la unión entre tramos.The Spanish utility model 1041681, by "Arrangement for splices of cable trays of type ladder ", proposes a cable tray configuration in which each of the profiles that forms the sides of the structure has at one of its ends a link device with the opposite end of the following profile, presenting the binary symmetry set with respect to a central axis perpendicular to the plane of the structure, allowing the fixing of each pair of structure sections by joining the elements male and female at the end of one of the sections with the corresponding female and male of the other. On the ends of the sections there are several attachment-fixing holes complementary to ensure the union between sections.

La patente europea EP 0373021 (validada en España como patente ES 2038838) propone un procedimiento de fabricación de una estructura ligera para soportar elementos como cables y canalizaciones en el que se emplean largueros cuya cara externa (la opuesta a la que toca los extremos de los travesaños) presenta una ancha garganta en forma de T abierta lateralmente y que guía en traslación los extremos de las mordazas; la mordaza se encastra en la garganta con forma de T y se fija a la pared externa del larguero, preferentemente mediante pegado.European patent EP 0373021 (validated in Spain as patent ES 2038838) proposes a procedure for manufacture of a light structure to support elements such as cables and pipes in which stringers are used whose face external (the opposite of the one that touches the ends of the crossbars) it has a wide T-shaped throat open laterally and which guides the ends of the jaws in translation; the gag is fits into the T-shaped throat and attaches to the outer wall of the stringer, preferably by gluing.

Se hace, pues, necesario un dispositivo de unión más simple y que permita obtener una unión segura entre tramos empleando un reducido número de piezas adicionales.A joining device is therefore necessary simpler and that allows to obtain a secure union between sections using a small number of additional pieces.

Descripción detallada de la invenciónDetailed description of the invention

En la figura 1 se observa una vista en perspectiva del conjunto formado por dos tramos 1, 2 de bandeja del tipo escalera para soportar cables de acuerdo con la invención, en una posición previa al acoplamiento.Figure 1 shows a view in perspective of the set formed by two sections 1, 2 of the tray ladder type for supporting cables according to the invention, in a position prior to coupling.

La bandeja del tipo escalera presenta una configuración general constituida por dos largueros 3 laterales paralelos y varios travesaños 4, 5 fijados entre dichos largueros 3 y separados entre sí, normalmente de manera uniforme. En el tramo 1, 2 de bandeja de la invención, cada larguero 3 comprende un extremo macho 6 y un extremo hembra 7, de tal modo que cada parte extrema del tramo 1, 2 de bandeja comprende el extremo macho 6 de un larguero 3 y el extremo hembra 7 del otro.The ladder type tray features a general configuration consisting of two lateral stringers 3 parallel and several crossbars 4, 5 fixed between said stringers 3 and separated from each other, usually uniformly. On the stretch 1, 2 tray of the invention, each stringer 3 comprises a male end 6 and one female end 7, such that each part end of section 1, 2 of tray comprises the male end 6 of a  stringer 3 and the female end 7 of the other.

En el extremo macho 6 sobresale una prolongación 9 central trapecial sustancialmente aplanada, situada entre dos pequeños escalonamientos 8 entrantes practicados en el borde 12 del extremo del larguero 3 correspondiente (véase la figura 2). Como se ve en la figura 1, la prolongación 9 se encuentra sobre un plano diferente al de la pared lateral del larguero 3, ligeramente metida con respecto a él.On the male end 6 an extension protrudes 9 substantially flattened trapezoidal central, located between two small steps 8 incoming practiced on the edge 12 of the end of the corresponding stringer 3 (see figure 2). How I know see in figure 1, the extension 9 is on a plane different from the side wall of the stringer 3, slightly inserted regarding him.

La prolongación 9 trapecial presenta un nervio 10 sobre su cara interna, que se prolonga ligeramente por la cara interna del larguero 3 correspondiente, y que es paralelo a su borde exterior. Dicha prolongación 9 trapecial presenta un orificio 11 en su parte central. Las figuras 2 y 3 permiten observar los detalles del extremo macho 6.Trapecial extension 9 has a nerve 10 on its inner face, which extends slightly down the face internal of the corresponding stringer 3, and which is parallel to its Outer edge. Said trapecial extension 9 has a hole 11 in its central part. Figures 2 and 3 allow us to observe the male end details 6.

El extremo hembra 7 comprende un par de guías 13 rectas inclinadas. Estas dos guías 13 presentan la misma inclinación, respectivamente, que los bordes superior e inferior de la prolongación 9 trapecial, y son divergentes hacia el extremo libre más próximo del larguero 3. Por otro lado, los extremos más próximos entre sí de las guías 13 están situados a una distancia del extremo libre más próximo del larguero 3 que es sustancialmente igual a la distancia entre el extremo libre de la prolongación 9 trapecial y el borde 12 del extremo macho 6 del larguero 3. Sobre la pared del larguero 3 del extremo hembra 7 hay practicado un orificio 14 pasante centrado entre ambas guías 13. Las figuras 2 y 4 permiten observar los detalles del extremo hembra 7.The female end 7 comprises a pair of guides 13 inclined lines These two guides 13 present the same inclination, respectively, that the upper and lower edges of the trapecial extension 9, and are divergent towards the end free nearest the stringer 3. On the other hand, the ends more next to each other of the guides 13 are located at a distance from the nearest free end of stringer 3 which is substantially equal to the distance between the free end of the extension 9 trapecial and edge 12 of male end 6 of stringer 3. Envelope the wall of the stringer 3 of the female end 7 there is a through hole 14 centered between both guides 13. Figures 2 and 4 allow to observe the details of the female end 7.

Las guías 13 se pueden formar a partir de la propia superficie lateral de los largueros 3, recortando y doblando la chapa en las zonas deseadas. De ese modo se obtienen una ventanas rectangulares en las caras laterales de los largueros 3 y se pueden formar dichas guías 13 mediante doblado. Preferentemente, las guías 13 tendrán una forma con sección en L, como se observa en la figura 4.The guides 13 can be formed from the own lateral surface of the stringers 3, trimming and folding the sheet in the desired areas. That way you get a rectangular windows on the side faces of the stringers 3 and said guides 13 can be formed by bending. Preferably the guides 13 will have an L-shaped shape, as seen in Figure 4

En una realización preferida las guías 13 se encuentran sobre la cara interna de los largueros 3, lo cual es preferible para facilitar su acoplamiento con las prolongaciones 9.In a preferred embodiment the guides 13 are found on the inner side of the stringers 3, which is preferable to facilitate its coupling with extensions 9.

Preferentemente, el orificio 11 practicado sobre la prolongación 9 trapecial es cuadrado y el orificio 14 practicado sobre la pared del larguero 3 y centrado entre las guías 13 es de forma rectangular y rasgado, como se observa mejor en la figura 2.Preferably, the hole 11 made on the trapecial extension 9 is square and the hole 14 practiced on the wall of the stringer 3 and centered between the guides 13 is of rectangular and torn shape, as best seen in the figure 2.

Al acoplarse ambos tramos 1, 2 de bandeja (véase la figura 1), e introducir el extremo macho 6 en el extremo hembra 7, el orificio 11 practicado sobre la prolongación 9 trapecial coincidirá con el orificio 14 practicado sobre la pared del larguero 3, lo que permitirá el empleo de un tornillo de cuello cuadrado para asegurar la unión, mejorando la continuidad eléctrica del conjunto.When coupling both sections 1, 2 of tray (see Figure 1), and insert the male end 6 into the female end 7, the hole 11 practiced on the trapecial extension 9 will coincide with the hole 14 made on the wall of the beam 3, which will allow the use of a neck screw square to ensure bonding, improving electrical continuity of the set

El hecho de que el orificio 14 practicado sobre el extremo hembra 7 sea alargado, permite que haya cierta holgura en la posición de la prolongación 9 trapecial (y, por tanto, del orificio 11 practicado en ella) con respecto al extremo hembra 7.The fact that hole 14 practiced on the female end 7 is elongated, allows some slack in the position of the trapecial extension 9 (and, therefore, of the hole 11 practiced therein) with respect to the female end 7.

Con la configuración descrita del extremo hembra 7 y el extremo macho 6 de los largueros 3 del tramo 1, 2 de bandeja de tipo escalera (véase la figura 1), al acoplar dichos extremos entre sí se introducen las prolongaciones 9 trapeciales sobre las guías 13 del extremo hembra 7 (véase la figura 2). Los nervios 10 entrantes de las prolongaciones 9 trapeciales permiten encajar dichas prolongaciones en las guías 13; éstas podrán abrirse ligeramente ante la presión de dichos nervios 10, debido a su elasticidad, ajustando el encaje y logrando un apriete adecuado.With the described configuration of the female end 7 and the male end 6 of the stringers 3 of the tray section 1, 2 ladder type (see figure 1), when coupling said ends the trapecial extensions 9 on each other are introduced guides 13 of the female end 7 (see Figure 2). The nerves 10 incoming 9 trapecial extensions allow to fit said extensions in guides 13; these can be opened slightly before the pressure of said nerves 10, due to its elasticity, adjusting the fit and achieving a tightening suitable.

Por otro lado, la forma complementaria de cuña de las guías 13 permite que la prolongación 9 trapecial quede bien encajada en ellas al llegar a su posición final, lo que evita holguras en el acoplamiento. Asimismo, los escalonamientos 8 entrantes practicados en el borde 12 del extremo macho 6 del larguero 3 hacen que, al enfrentarse ambos tramos 1, 2 de bandeja, se consiga hacer tope entre el borde 12 del extremo macho 6 y el del extremo hembra 7.On the other hand, the complementary wedge shape of the guides 13 allows the trapecial extension 9 to be well embedded in them when they reach their final position, which avoids clearances in the coupling. Also, the steps 8 starters made at the edge 12 of the male end 6 of the stringer 3 make that, when facing both sections 1, 2 of tray, a stop is made between the edge 12 of the male end 6 and the of the female end 7.

Como se observa en la figura 2, los nervios 10 situados sobre la cara interna de la prolongación 9 trapecial se prolongan ligeramente por la cara interna del larguero 3 correspondiente, lo cual permite dotar a dicha prolongación 9 trapecial de mayor rigidez, especialmente cuando se encuentra acoplada con la guía 13 correspondiente.As seen in Figure 2, the nerves 10 located on the inner face of the trapecial extension 9 is extend slightly along the inner side of the crossbar 3 corresponding, which allows the extension 9 trapezoid of greater rigidity, especially when it is coupled with the corresponding guide 13.

En las figuras 5 y 6 aparece representado en detalle el sistema empleado para la unión de los travesaños 4, 5 a los largueros 3 de los tramos 1, 2 de bandeja. Los largueros 3 comprenden unas embuticiones 15 rectangulares distribuidas uniformemente sobre sus caras principales. Dichas embuticiones 15 presentan dos ranuras 16 laterales, en las que pueden insertarse sendas lengüetas 17 situadas sobre los extremos de cada travesaño 4, 5, como se observa mejor en la figura 6. En su parte central, además, las embuticiones 15 pueden presentar sendas perforaciones 18 centrales, situadas entre las ranuras 16, cuya función es permitir la evacuación del zinc fundido, en caso de aplicar un acabado protector mediante galvanizado en caliente.In figures 5 and 6 it is represented in detail the system used for joining the crossbars 4, 5 a the stringers 3 of the sections 1, 2 of tray. The stringers 3 they comprise distributed rectangular embossments 15 evenly over their main faces. Sausages 15 they have two lateral grooves 16, in which they can be inserted two tabs 17 located on the ends of each crossbar 4, 5, as best seen in Figure 6. In its central part, In addition, the drawing 15 can have perforations 18 centrals, located between slots 16, whose function is allow the evacuation of molten zinc, in case of applying a protective finish by hot dip galvanizing.

En las ranuras 16 se introducen a presión las lengüetas 17, de modo que posteriormente pueden doblarse hacia dentro (es decir, hacia la perforación 18 central) o bien hacia fuera.In the grooves 16, the tabs 17, so that later they can be bent towards inside (that is, towards the central perforation 18) or towards outside.

La disposición de las dos lengüetas 17 permite el montaje de los travesaños 4, 5 en los largueros 3 con las aberturas hacia arriba (travesaño 5) o con las aberturas hacia abajo (travesaño 4), según se observa en las figuras 1 y 7. El hecho de que el número de lengüetas 17 sea de dos en cada extremo de los travesaños permite que un mismo travesaño 4, 5 (véase la figura 7) pueda montarse con las aberturas hacia arriba o hacia abajo (véase la figura 1), siendo ambos casos habituales en este tipo de bandeja de escalera.The arrangement of the two tabs 17 allows the mounting of the crossbars 4, 5 on the stringers 3 with the openings up (crossbar 5) or with openings facing below (crossbar 4), as seen in Figures 1 and 7. The fact that the number of tabs 17 is two at each end of  the crossbars allow the same crossbar 4, 5 (see figure 7) can be mounted with openings up or down (see Figure 1), both cases being common in this type of ladder tray
