DESCRIPCIÓN OBJETO DE LA INVENCIÓN DESCRIPTION OBJECT OF THE INVENTION

La invención, dispositivo para extraer cajas base de balizas empotradas, se refiere a un dispositivo cuya finalidad es permitir la extracción, rápida y sin importad la integridad, de las cajas base en que se incorporan las balizas, en particular de las balizas de señalización luminosa que se disponen empotradas en el pavimento, estando estructuralmente diseñado con unos brazos expansivos que proporcionan unos medios de fijación a dicha caja base tales que, al tirar de él, con ayuda de medios de sustentación y accionamiento apropiados, se traban bajo el marco perimetral que presenta el borde superior de dicha caja base, permitiendo efectuar la extracción de dicha caja base tirando hacia arriba de la misma. En concreto, la extracción rápida de la caja base puede provocar que la misma sea extraída deformada de manera que queda invalidada para su utilización posterior. The invention, a device for extracting base boxes from recessed beacons, refers to a device whose purpose is to allow the extraction, quickly and regardless of integrity, of the base boxes in which the beacons are incorporated, in particular of the light signaling beacons which are arranged embedded in the pavement, being structurally designed with expansive arms that provide fixing means to said base box such that, when pulled, with the help of appropriate support and actuation means, they are locked under the perimeter frame that it has the upper edge of said base box, allowing the removal of said base box by pulling it upwards. In particular, the rapid removal of the base box can cause it to be removed deformed so that it is invalidated for later use.

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de aparatos y dispositivos para la extracción de elementos empotrados en el terreno. The field of application of the present invention is part of the industry sector dedicated to the manufacture of devices and devices for the extraction of embedded elements in the field.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Como es sabido, las balizas empotradas son dispositivos para la señalización luminosa de viales, calles o carriles de carreteras, autopistas y otras vías de circulación, para pistas de aeropuertos y para emplazamientos similares durante la noche o en condiciones de baja visibilidad. As is known, embedded beacons are devices for the light signaling of roads, streets or lanes of roads, highways and other roads, for airport runways and for similar locations at night or in low visibility conditions.

Dichas balizas están incorporadas al terreno alojadas dentro de una caja base que es la parte que queda empotrada en un hueco practicado al efecto en el pavimento, presentando, normalmente, una configuración circular con un reborde superior en el que se fija la baliza propiamente dicha y que queda a ras del pavimento. Said beacons are incorporated into the ground housed within a base box that is the part that is embedded in a hole made for this purpose in the pavement, normally presenting a circular configuration with an upper flange in which the beacon itself is fixed and that is flush with the pavement.

Para proceder a la retirada de estas balizas, cuando es necesario por motivos de reparación o sustitución, y evitar la necesidad de emplear una fresa o corona de diámetro mayor que la caja para hacer una perforación concéntrica alrededor de la misma y demoler el contorno que podría deteriorar las conexiones y la propia baliza, ya que la caja se fija al asfalto mediante resina o mortero, por el documento WO2016075346A1, se conoce un útil que, comprendiendo una estructura de soporte al terreno, unos medios de fijación sobre el borde superior de la caja base de una baliza y unos medios de desplazamiento lineal unidos a estos último y dotados de medios de accionamiento acoplados al soporte, proporciona un To proceed with the removal of these beacons, when necessary for reasons of repair or replacement, and avoid the need to use a drill or crown larger than the box to make a concentric perforation around it and demolish the contour that could deteriorate the connections and the beacon itself, since the box is fixed to the asphalt by resin or mortar, from WO2016075346A1, a tool is known which, comprising a support structure to the ground, fixing means on the upper edge of the base box of a beacon and linear displacement means attached to the latter and provided with actuating means coupled to the support, provides a

sistema para la extracción de las balizas y de sus cajas. system for the extraction of beacons and their boxes.

Sin embargo, dicho útil, presenta ciertos aspectos susceptibles de ser mejorados, ya que, si bien los elementos que comprende, en cuanto al soporte que lo fija al terreno y en cuanto a los medios de desplazamiento y accionamiento de los medios de fijación al borde de la caja baliza, cumplen satisfactoriamente su cometido, no ocurre lo mismo con dichos medios de fijación al borde de la caja de la baliza y que, de hecho, constituyen la parte más importante del útil, ya que, en su opción preferida, precisan de una fijación atornillada en dicho borde, lo cual supone que el borde esté en condiciones de recibir dicho atornillado, cosa que puede no ocurrir, además de invertir un tiempo considerable de actuación por parte de los operarios que llevan a cabo la extracción. However, said tool has certain aspects that can be improved, since, although the elements that it comprises, in terms of the support that fixes it to the ground and in terms of the means of movement and actuation of the means for fixing to the edge of the beacon box, they satisfactorily fulfill their task, the same does not happen with said fixing means at the edge of the beacon box and which, in fact, constitute the most important part of the tool, since, in their preferred option, they need of a fastening screwed on said edge, which means that the edge is in a position to receive said screwed, which may not occur, in addition to investing a considerable time of action by the operators who carry out the extraction.

Asimismo, alternativamente los citados medios de fijación al borde de la caja de la baliza son tales que quedan bajo el borde perimetral superior de la caja de la baliza, si bien no se describen específicamente, siendo justamente el objetivo de la presente invención el desarrollo de un dispositivo dotado con una configuración estructural que incluye dicho tipo de medios de sujeción para que, de manera automática, queden trabados en el mencionado borde de la caja y permitir la extracción de la misma al tirar hacia arriba del conjunto del dispositivo. Likewise, alternatively said means for fixing to the edge of the beacon box are such that they remain under the upper perimeter edge of the beacon box, although they are not specifically described, the objective of the present invention being precisely the development of a device equipped with a structural configuration that includes said type of fastening means so that, automatically, they are locked in the mentioned edge of the box and allow its removal when the device assembly is pulled up.

EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION

Así, el dispositivo para extraer cajas base de balizas empotradas que la invención propone es un dispositivo de para la extracción de la caja base de una baliza empotrada en el terreno que, preferiblemente destinado a su sustentación a través de una estructura de soporte al terreno y con medios accionamiento para su desplazamiento lineal, determina un medio de fijación al borde superior de la caja base tal que, al tirar de él hacia arriba, se efectúa la extracción de dicha caja. Más específicamente, dichos medios de fijación a la caja base se traban bajo el marco perimetral del mencionado borde superior de la caja, con la particularidad de estar determinados por sendos brazos que se expanden y se traban bajo dicho marco de manera automática al tirar del dispositivo hacia arriba. Para ello, se tiene que retirar la óptica de la baliza y que tras ser retirada deja visible una abertura que da acceso al interior de la caja base. El dispositivo de la presente invención, se introduce en el interior de dicha caja base a través de la abertura para así proceder a la extracción de la misma. Thus, the device for extracting base boxes from embedded beacons that the invention proposes is a device for extracting the base box from a recessed beacon on the ground which, preferably intended for its support through a ground support structure and with drive means for its linear displacement, it determines a fixing means to the upper edge of the base box such that, when pulled upwards, said box is removed. More specifically, said fixing means to the base box are locked under the perimeter frame of said upper edge of the box, with the particularity of being determined by two arms that expand and lock under said frame automatically when pulling the device upwards. To do this, the optics of the beacon must be removed and after being removed it leaves an opening visible that gives access to the interior of the base box. The device of the present invention is introduced inside said base box through the opening in order to proceed to the extraction thereof.

Por lo tanto es objeto de la presente invención un dispositivo según la reivindicación Therefore, a device according to claim is the subject of the present invention.

1. one.

Para ello, el dispositivo se configura a partir de un vástago central superior, con medios para su unión al mencionado soporte y procurar su sustentación en el mismo a través de su parte superior, y presentando acoplados en su parte inferior, mediante un primer eje transversal y por sendos lados opuestos del mismo, el extremo superior de sendas pletinas paralelas e idénticas entre las que, insertado en respectivas ranuras verticales, incorpora un segundo eje, en este caso deslizante a lo largo de dichas ranuras, que constituye la unión articulada de los antedichos brazos expansivos, existiendo, además, un tercer eje transversal que une entre sí los extremos inferiores de las pletinas. For this, the device is configured from an upper central rod, with means for its attachment to the mentioned support and ensure its support therein through its upper part, and presenting coupled at its lower part, by means of a first transverse axis and on opposite sides thereof, the upper end of parallel and identical flat paths between which, inserted in respective vertical grooves, incorporates a second axis, in this case sliding along said grooves, which constitutes the articulated joint of the Said expansive arms, there being, in addition, a third transverse axis that joins the lower ends of the plates together.

De esta manera, al tirar hacia arriba del vástago central superior, se elevan con él las pletinas paralelas, con lo cual el tercer eje transversal empuja los brazos por la zona central inferior de los mismos provocando una ligera elevación de estos y, consecuentemente, su expansión hacia extremos opuestos, al mismo tiempo que el eje deslizante que constituye la unión articulada entre ellos se desliza en las ranuras de dichas pletinas. In this way, when pulling up the upper central rod, the parallel plates rise with it, whereby the third transverse axis pushes the arms through the lower central area of the same causing a slight elevation of these and, consequently, their expansion towards opposite ends, at the same time as the sliding axis that constitutes the articulated joint between them slides in the grooves of said plates.

Esta disposición permite que la fuerza de expansión de los brazos sea mayor cuanto mayor sea el tiro de extracción. Además, el dispositivo es regulable en fuerza hacia los lados, mediante la incorporación de un resorte que vincula ambos brazos entre sí tendiendo a mantenerlos unidos, permitiendo que se bloquee la fuerza de expansión en un determinado punto para no romper hacia el exterior la caja base. This arrangement allows the expansion force of the arms to be greater the greater the extraction throw. In addition, the device is adjustable in force to the sides, by incorporating a spring that links both arms together, tending to hold them together, allowing the expansion force to be blocked at a certain point so as not to break the base box outwards. .

Cabe destacar que, en los extremos distales de ambos brazos se han previsto correspondientes engrosamientos en arco, de radio coincidente con el radio de la caja base a extraer, que, unidos solidariamente a los extremos de dichos brazos, determinan la parte del dispositivo que quedará trabada bajo el marco perimetral del borde superior de la caja base. Además, la inclinación de dichos engrosamientos así como las dimensiones de los brazos, en posición expandida, serán las necesarias para encajar dichos engrosamientos ajustados entre la pared interior de la caja base. It should be noted that, at the distal ends of both arms, corresponding arc thickening is provided, with a radius coinciding with the radius of the base box to be extracted, which, jointly and severally attached to the ends of said arms, determines the part of the device that will remain locked under the perimeter frame of the upper edge of the base box. In addition, the inclination of said thickening as well as the dimensions of the arms, in an expanded position, will be those necessary to fit said thickening between the inner wall of the base box.

Con ello, el dispositivo, normalmente incorporado en el útil ya descrito, se desliza en un movimiento lineal para hacerlo descender y penetrar dentro de la caja base a través de la embocadura de la misma, disponiendo los brazos en posición plegada de reposo, y una vez traspasado el marco, se procede a tirar hacia arriba del vástago superior central, provocando la expansión de los brazos y el subsiguiente trabado de los extremos engrosados bajo el marco perimetral del borde superior y, posteriormente, la extracción de la caja base, tirando de ella hacia arriba. With this, the device, normally incorporated in the tool already described, slides in a linear motion to make it descend and penetrate into the base box through the mouth of the same, placing the arms in the folded rest position, and a Once the frame is passed, the upper central stem is pulled up, causing the arms to expand and the subsequent locking of the thickened ends under the perimeter frame of the upper edge and, subsequently, the removal of the base box, pulling She up.
