Description

Dispositivo de empalme de tramos de bandeja portacables del tipo escalera, tramo de bandeja y procedimiento de sustitución de dichos tramos.Tray section splicing device cable-type ladder, tray section and procedure replacement of said sections.

Campo de la invenciónField of the Invention

La presente invención se refiere a un dispositivo de empalme de tramos de bandeja portacables, en especial de bandejas del tipo escalera de las que se emplean para soportar cables eléctricos, a un tramo de bandeja y a un procedimiento de sustitución (desmontaje y montaje) de dichos tramos de bandeja. 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 splice device of cable tray sections, especially of ladder type trays that are used to support electrical cables, a section of tray and a procedure of replacement (disassembly and assembly) of said tray sections. Said sections of the ladder type tray are those constituted by two stringers or side profiles and several arranged crossbars between the stringers and spaced apart from each other throughout its length.

Antecedentes de la invenciónBackground of the invention

Las instalaciones con bandejas portacables del tipo escalera están constituidas por varios tramos de estas bandejas unidos entre sí.The installations with cable trays stair type are made up of several sections of these trays joined together.

Es frecuente utilizar 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 costoso, a lo que habría 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.It is common to use two joining plates and several screws and nuts (whose number could be 8 or more) to execute the union between two sections, which is slow and expensive, to which we would have 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 the that 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 set binary symmetry with respect to a central axis perpendicular to the plane of the structure, allowing the fixation of each pair of stretches of structure by joining the male elements and female end of one of the sections with the corresponding female and male of the other. On the ends of the sections there are several complementary attachment-fixing holes that allow 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 that guide 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.

El modelo de utilidad español 1069986, por "Dispositivo de empalme de tramos de bandeja del tipo escalera para soportar cables", describe un dispositivo con una prolongación central trapecial aplanada en uno de los extremos de un larguero, y, en el otro extremo, un par de guías rectas inclinadas con la misma inclinación que los bordes superior e inferior de la prolongación trapecial.The Spanish utility model 1069986, by "Device for splicing tray sections of the ladder type to support cables, "describes a device with a trapecial central extension flattened at one end of a stringer, and, at the other end, a pair of inclined straight guides with the same inclination as the upper and lower edges of the trapecial extension.

El modelo de utilidad español 1073243, por "Dispositivo de empalme de tramos de bandeja del tipo escalera", describe un sistema con una prolongación en sentido longitudinal, ligeramente metida con respecto al plano de la pared lateral del larguero, cuyos contornos superior e inferior son paralelos, y con una embutición hacia dentro cuyo borde interno es biselado, teniendo esta prolongación practicado un orificio pasante, y, en el otro extremo, un par de guías rectas paralelas, que delimitan un hueco cuya altura es ligeramente superior a la altura de la prolongación.The Spanish utility model 1073243, by "Device for splicing tray sections of type ladder ", describes a system with an extension in the direction longitudinal, slightly inserted with respect to the plane of the wall lateral of the stringer, whose upper and lower contours are parallel, and with an inward drawing whose inner edge is bevelled, having this extension made a through hole, and, at the other end, a pair of parallel straight guides, which delimit a gap whose height is slightly higher than the height of the extension.

Los dispositivos de empalme que no necesitan placas adicionales de unión permiten el montaje y desmontaje de tramos intermedios de bandeja portacables desplazando longitudinalmente los tramos colindantes.Splicing devices that do not need additional joining plates allow the assembly and disassembly of intermediate sections of cable tray moving longitudinally adjacent sections.

En estos casos, el hecho de sustituir un tramo de bandeja portacables cuando la instalación ya está terminada resulta bastante engorroso, ya que hay que desplazar los tramos colindantes al que se desea sustituir. Este inconveniente resulta aún más claro en las bandejas portacables de escalera, las cuales soportan un peso y una tensión considerable de cables.In these cases, the fact of replacing a section cable tray when installation is finished It is quite cumbersome, since you have to move the sections adjacent to which you want to replace. This inconvenience results even clearer in the ladder cable trays, which they support a considerable weight and tension of cables.

Se hace, pues, necesario un dispositivo de unión simple que permita sustituir tramos intermedios de bandeja portacables de manera sencilla.A joining device is therefore necessary simple to replace intermediate sections of tray cable holder in a simple way.

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 que incorporan el dispositivo 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 to support cables that incorporate the device 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 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 12 y un extremo hembra 7, de tal modo que cada parte extrema del tramo 1, 2 de bandeja comprende el extremo macho 12 de un larguero 3 y el extremo hembra 7 del otro. El dispositivo de empalme, pues, está constituido por los extremos macho 12 y hembra 7 de los largueros 3 situados sobre cada extremo del tramo de bandeja.The ladder type tray features a general configuration consisting of two lateral stringers 3 parallel and several crossbars 4 fixed between said stringers 3 and separated from each other, usually uniformly. In section 1, 2 of tray of the invention, each stringer 3 comprises one end male 12 and one female end 7, such that each end part of the tray section 1, 2 comprises the male end 12 of a stringer 3 and the female end 7 of the other. The device of splice, then, is constituted by male 12 and female 7 of the stringers 3 located on each end of the section of tray.

En la figura 1 se observa que cada extremo macho 12 comprende una prolongación 5 en sentido longitudinal. Esta prolongación 5 está ligeramente metida con respecto al plano de la cara interior de la pared lateral del larguero 3 correspondiente y es paralela a ella, con sus contornos superior e inferior paralelos entre sí y su contorno superior a menor altura que el contorno superior de la pared lateral correspondiente. Sobre está prolongación 5 se practica al menos un orificio pasante 6, de contorno rectangular en la realización mostrada en las figuras.Figure 1 shows that each male end 12 comprises an extension 5 in the longitudinal direction. This extension 5 is slightly inserted with respect to the plane of the inner side of the side wall of the corresponding stringer 3 and It is parallel to it, with its upper and lower contours parallel each other and its upper contour at a lower height than the contour upper side wall corresponding. About this extension 5 at least one through hole 6 is made of rectangular contour in the embodiment shown in the figures.

En dicha figura 1 también se observa que cada extremo hembra 7 tiene la cara interior de su pared lateral plana, con orificios 8 situados a una distancia del borde libre de dicho extremo sustancialmente igual a la distancia entre cada orificio 6 correspondiente practicado sobre la prolongación 5 y el borde libre de la pared lateral en el extremo del otro larguero 3, y situado sustancialmente a la misma altura que el orificio 6 correspondiente practicado sobre la prolongación 5. En la figura se observa que existen cuatro orificios 6 rectangulares practicados en la prolongación 5, y que el extremo hembra 7 presenta asimismo cuatro orificios 8, también rectangulares en dicha figura, en correspondencia con las posiciones relativas de los orificios 6 de la prolongación 5.In said figure 1 it is also observed that each female end 7 has the inside face of its flat side wall, with holes 8 located at a distance from the free edge of said end substantially equal to the distance between each hole 6 corresponding practiced on extension 5 and the free edge of the side wall at the end of the other stringer 3, and located substantially at the same height as the corresponding hole 6 practiced on prolongation 5. The figure shows that there are four rectangular holes 6 made in the extension 5, and that the female end 7 also has four holes 8, also rectangular in said figure, in correspondence with the relative positions of holes 6 of the extension 5.

En esta realización, los orificios 6 de la prolongación 5 y los practicados sobre la pared del larguero 3 en su extremo hembra 7 son rectangulares y de iguales dimensiones.In this embodiment, the holes 6 of the extension 5 and those practiced on the wall of the stringer 3 in its Female end 7 are rectangular and of equal dimensions.

En dicha figura 1 se observa asimismo que la prolongación 5 tiene esquinas redondeadas 9 en sus extremos superior e inferior, lo que evita los cortes en el usuario durante la manipulación del producto y también en los propios cables 11 que irán apoyados sobre la bandeja.In said figure 1 it is also observed that the extension 5 has rounded corners 9 at its upper ends and lower, which prevents cuts in the user during the product handling and also on the cables 11 themselves that They will rest on the tray.

En las figuras 4 a 10 se observa que el tramo 1, 1', 2 de bandeja portacables que incorpora en cada uno de sus dos extremos un dispositivo de empalme como el descrito tiene un extremo macho 12 y un extremo hembra 7 opuesto en cada uno de sus largueros 3.In figures 4 to 10 it can be seen that section 1, 1 ', 2 cable tray that incorporates in each of its two ends a splicing device like the one described has an end male 12 and an opposite female end 7 on each of its stringers 3.

Al acoplarse ambos tramos 1, 2 de bandeja (véanse las figuras 1 y 2), e introducir el extremo macho 12 en el extremo hembra 7, los orificios 6 practicados sobre la prolongación 5 coincidirán con los orificios 8 practicados sobre la pared del larguero 3, lo que permitirá el empleo de medios 10 de unión (por ejemplo, conjuntos formados por tornillo y tuerca) para asegurar la fijación (véase la figura 3). Se observa también que se consigue un efecto de doble pared en la unión, al insertarse la prolongación 5 en el extremo hembra 7 correspondiente.When coupling both sections 1, 2 of tray (see Figures 1 and 2), and insert the male end 12 into the female end 7, the holes 6 made on the extension 5 will coincide with the holes 8 made on the wall of the beam 3, which will allow the use of joining means 10 (for example, sets formed by screw and nut) to ensure the fixing (see figure 3). It is also observed that a double wall effect at the junction, when the extension 5 is inserted at the corresponding female end 7.
