Dispositivo de enganche de seguridad semiautomático para moldes de construcción de pilares.Safety hitch device semi-automatic for pillar construction molds.

Object of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo de enganche de seguridad semiautomático para moldes utilizados en la construcción de pilares, dispositivo que presenta unas características que permiten realizar a distancia el desenganche del molde sin necesidad de que el operario tenga que desplazarse al lugar en el que se pretende dejar dicho molde.The present invention, as expressed in the set forth in this specification, refers to a device semiautomatic safety hitch for molds used in the construction of pillars, device that presents some features that allow remote disengagement of the mold without the need for the operator to move to the place where it is intended to leave said mold.

El objeto de la invención es proporcionar al público en general y al sector de la construcción en particular, un dispositivo de enganche para elevar mediante grúa los moldes metálicos que normalmente se utilizan como fundas en la formación de pilares de hormigón, de manera que el dispositivo en cuestión cuenta con medios de seguridad que mantienen eficazmente asegurado el molde, pudiendo dichos medios ser accionados a distancia para conseguir el desenganchado, evitando con ello que el operario tenga que desplazarse (subir o bajar) hasta el lugar en el que es factible el alcance manual del enganche para llevar a cabo la operación de desenganche.The object of the invention is to provide the general public and the construction sector in particular, a hooking device to lift the molds by crane Metals that are normally used as covers in the formation of concrete pillars, so that the device in question it has security means that keep it effectively insured the mold, said means being able to be operated remotely to get the disengagement, thereby preventing the operator from having to move (up or down) to the place where it is feasible the manual reach of the hitch to carry out the Disengagement operation

Background of the invention

Como es sabido, en la formación de pilares de hormigón se utilizan unos paneles metálicos o perfiles unidos entre sí para formar una funda o molde tubular que se dispone de forma vertical para depositar sobre el mismo una cantidad de hormigón hasta su llenado, mediante la que se formará un pilar. Una vez fraguado dicho hormigón, el moldeo o funda debe ser retirado para su reutilización.As is known, in the formation of pillars of concrete are used metal panels or profiles joined between yes to form a tubular sheath or mold that is arranged so vertical to deposit on it a quantity of concrete until filling, by which a pillar will be formed. One time setting said concrete, the molding or sheath must be removed to its reuse

Lógicamente, la reutilización se efectuará en una planta superior de la edificación, lo que exige la elevación de cada uno de los moldes hasta esa planta superior, operación que se realiza mediante una grúa a cuyo cable hay que engancharlo o desengancharlo manualmente por parte de un operario, que como es evidente, debe estar en esa planta para llevar a efecto el desenganche.Logically, the reuse will take place in a upper floor of the building, which requires the elevation of each of the molds to that upper floor, operation that made by means of a crane whose cable must be hooked or unhook it manually by an operator, which as is Obviously, it must be on that floor to carry out the disengagement

Como es fácil de deducir, esa operación de enganche y desenganche, además de suponer una pérdida de tiempo por parte del operario, también supone un riesgo de accidente al tener que trepar escaleras que normalmente no están convenientemente acondicionadas, a no ser que intervengan dos operarios, uno en la planta superior y otro en la planta inferior.As it is easy to deduce, that operation of hooking and unhooking, in addition to assuming a waste of time by part of the operator, also involves an accident risk by having to climb stairs that are normally not conveniently conditioned, unless two operators intervene, one in the upper floor and another on the lower floor.

Por otro lado, los ganchos o dispositivos utilizados para suspender de la grúa el molde o funda para la formación de pilas de hormigón, están constituidos de manera tal que el desenganche debe efectuarse manualmente, sin posibilidad de poder realizar un desenganchado a distancia.On the other hand, hooks or devices used to suspend the mold or sheath for the crane formation of concrete piles, are constituted in such a way that the release must be done manually, without the possibility of be able to perform a remote disengagement.

En tal sentido, actualmente los moldes son suspendidos de forma rudimentaria mediante la colocación por parte del operario de unas gavillas que se colocan insertándose en unos orificios, actuando como si fuesen un asa de cubo, de manera que la grúa sostiene por dicho asa o gavilla el molde y lo transporta con grave riesgo de desprendimiento, debido a la escasa sujeción del improvisado asa.In that sense, currently the molds are suspended in a rudimentary way by placement of the operator of some sheaves that are placed by inserting into holes, acting as if they were a bucket handle, so that the crane holds the mold by said handle or sheaf and transports it with severe risk of detachment, due to poor grip on the improvised handle.

Description of the invention

El dispositivo de enganche de la invención presenta unas características tales que puede decirse es de actuación semiautomática, ya que si bien el enganche del molde o funda debe hacerse manualmente, sin embargo el desenganche puede realizarse a distancia mediante una especie de pértiga o elemento similar, mediante el cual un operario lleva a cabo el desenganche correspondiente, aunque el molde se encuentre en otra planta de la edificación.The coupling device of the invention It has characteristics that can be said to be semi-automatic action, since although the mold hitch or cover must be done manually, however the release can be carried out remotely using a kind of pole or element similar, whereby an operator performs the release corresponding, although the mold is on another floor of the edification.

Concretamente, el gancho de la invención presenta la particularidad de constituirse a partir de un cuerpo con una abertura lateral e inferior para situar la misma sobre el correspondiente ala con que cuenta cada una de las aristas del molde, presentando un tetón externo a la abertura para su alojamiento en un orificio de dicho ala del molde.Specifically, the hook of the invention has the peculiarity of being constituted from a body with a side and bottom opening to place it over the corresponding wing that has each of the edges of the mold, presenting an external stud to the opening for its housing in a hole of said mold wing.

La sujeción del molde se efectuará mediante dos ganchos, uno a cada lado del molde, para manipular éste en vertical mediante la correspondiente grúa, contando ésta con dos cables, cada uno de los cuales será portador en su extremo libre del gancho de la invención, que queda sujeto al cable a través de un mosquetón o elemento similar establecido al efecto en éste.The mold will be fastened by two hooks, one on each side of the mold, to handle it vertically by means of the corresponding crane, counting this one with two cables, each of which will be a carrier at its free end of the hook of the invention, which is attached to the cable through a carabiner or similar element established for this purpose.

Además, el cuerpo del dispositivo presenta un pasador o vástago vertical y retráctil, ubicado en una conformación tubular superior a la parte dotada de la abertura anteriormente referida, pasador o vástago del que emerge lateralmente un brazo acodado que sale al exterior a través de una ventana vertical y lateral, permitiendo el desplazamiento ascendente/descendente de tal pasador, el cual es pasante por dos orificios enfrentados previstos en las dos alas entre las que se determina la abertura lateral comentada, de manera que en la posición de descenso de tal pasador, en contra de un muelle que actúa como elemento retráctil de recuperación de aquél en su posición de reposo o inoperante, el extremo inferior del repetido pasador o vástago queda situado transversalmente a la abertura lateral e inferior del cuerpo del dispositivo, alojándose por su extremo libre en un orificio del propio ala de la arista del molde, para conseguir la solidarización entre gancho y molde, manteniéndose el bloqueo de tal posición en virtud de que mediante un leve giro del brazo acodado, éste se ubica en una escotadura lateral a la ventana de emergencia de tal brazo.In addition, the body of the device has a vertical and retractable pin or rod, located in a conformation tubular superior to the part provided with the opening above referred, pin or stem from which an arm emerges laterally layered that goes outside through a vertical window and lateral, allowing upward / downward displacement of such pin, which is passed through two facing holes provided on the two wings between which the lateral opening is determined commented, so that in the position of descent of such pin, against a spring that acts as a retractable element of recovery of the one in his resting or inoperative position, the lower end of the repeated pin or rod is located transversely to the lateral and inferior opening of the body of the device, staying at its free end in a hole in the own wing of the edge of the mold, to achieve solidarity between hook and mold, keeping the lock of such position in virtue that by a slight turn of the cranked arm, it located in a side recess to the emergency window of such arm.

Para el desbloqueo de ese enganche bastará con traccionar y girar levemente a distancia, mediante la ya comentada pértiga o elemento alargado similar, del acodamiento del brazo lateral correspondiente del vástago o pasador, para volver a posicionar dicho brazo en la ventana del cuerpo, siendo retraído tal vástago o pasador por el muelle para ocupar su posición de empuje hacia arriba, desenclavándose del orificio del ala lateral del molde, con lo que el gancho queda liberado de éste. Esta operación de desenganche o desbloqueo se realizará a distancia mediante un útil apropiado, tal como una especie de pértiga rígida rematada con la forma apropiada para poder traccionar del brazo lateral del pasador de bloqueo.For the release of that hitch will suffice with pull and turn slightly at a distance, using the one already mentioned Pole or similar elongated element of the arm bending corresponding side of the rod or pin, to return to position said arm in the body window, being retracted such rod or pin by the spring to occupy its position of push up, unlocking from the side wing hole of the mold, with which the hook is released from it. This unlocking or unlocking operation will be performed remotely by an appropriate tool, such as a kind of rigid pole finished off with the appropriate form to be able to pull the arm side of the locking pin.

El cuerpo general del dispositivo de enganche se complementa con un puente o semianilla superior giratoria, para su vinculación o enganche al correspondiente elemento (tal como un mosquetón o similar) previsto al efecto en el extremo de cada uno de los dos cables con que la grúa cuenta para poder enganchar de dos puntos el molde.The general body of the hitch device is complements with a rotating bridge or upper half-ring, for its linking or hooking to the corresponding element (such as a carabiner or similar) provided for that purpose at the end of each of the two cables that the crane has to be able to hook Two points the mold.

De esta forma se consigue un dispositivo o gancho que permite una más fácil, rápida y cómoda manipulación de los moldes utilizados para la formación de pilares de hormigón en la construcción, con la ventaja de resultar de alta seguridad, ya que la abertura lateral del cuerpo del dispositivo para ubicación del ala del molde, en colaboración con el pivote lateral a esa abertura y del pasador o vástago de enclavamiento, proporcionan al conjunto del dispositivo de enganche tres puntos de seguridad, evitándose el riesgo de accidentes que tan frecuentes resultan en la construcción.This way you get a device or hook which allows easier, faster and more convenient handling of molds used for the formation of concrete pillars in the construction, with the advantage of being high security, since the lateral opening of the device body for location of the mold wing, in collaboration with the side pivot to that opening and of the pin or interlocking rod, they provide the set of the hook-up device three safety points, avoiding the risk of accidents that are so frequent in the building.

A la vista de las comentadas figuras, puede observarse cómo el dispositivo de la invención se constituye a partir de un cuerpo en el que se establece una parte inferior con una abertura lateral 1 que da lugar a una pareja de alas, una superior 2 y otra inferior 3, prolongándose ésta en un tramo lateral 3' con un tetón 4 proyectado hacia arriba, mientras que del ala superior 2 correspondiente a la abertura lateral 1, se proyecta una conformación tubular 5 en la que queda alojado axialmente y con facultad de desplazamiento ascendente y descendente un vástago o pasador 6 requerido hacia una posición de ascenso por medio de un muelle 7, con la particularidad de que el extremo libre de ese vástago o pasador 6, en su posición de descenso en contra de la acción del resorte o muelle 7, es pasante a través de sendos orificios enfrentados 8' previstos al efecto en las alas 2 y 3 que delimitan la abertura lateral 1.In view of the commented figures, you can observe how the device of the invention is constituted to from a body in which a lower part is established with a side opening 1 that gives rise to a pair of wings, a upper 2 and lower 3, extending this in a section 3 'side with a bust 4 projected upwards, while the upper wing 2 corresponding to the side opening 1, is projected a tubular conformation 5 in which it is axially housed and with faculty of upward and downward displacement a stem or pin 6 required towards an ascending position by means of a spring 7, with the particularity that the free end of that rod or pin 6, in its downward position against the spring or spring action 7, is passed through each other 8 'facing holes provided for the purpose on wings 2 and 3 that delimit the lateral opening 1.

El pasador o vástago 6 presenta un brazo lateral 9 que emerge hacia el exterior y se acoda determinando un corto tramo superior ascendente 9' cuya función se expondrá con posterioridad, con la particularidad de que ese brazo 9 en los desplazamientos ascendente y descendente del vástago o pasador 6 se guía en una ranura o ventana vertical 10 prevista al efecto en el cuerpo tubular 5, y cuya ventana o ranura 10 se complementa con una escotadura lateral e inferior 8 en la que es susceptible de situarse el brazo 9 en la posición de descenso del vástago o pasador 6, ya que en la posición de ascenso el brazo 9 queda en el extremo superior de la ventana o ranura 10 por estar traccionando o empujando hacia arriba el muelle 7 al propio vástago 6 y por lo tanto al brazo 9 emergente lateralmente de tal brazo.The pin or rod 6 has a side arm 9 that emerges outward and layered determining a short upper section ascending 9 'whose function will be exposed with later, with the particularity that this arm 9 in the upward and downward displacements of the rod or pin 6 se guide in a slot or vertical window 10 provided for this purpose in the tubular body 5, and whose window or groove 10 is complemented by a lateral and lower recess 8 in which it is susceptible to put the arm 9 in the rod drop position or pin 6, since in the ascent position the arm 9 is in the upper end of the window or slot 10 for being pulling or pushing the spring 7 up to the stem 6 itself and so both to arm 9 emerging laterally from such arm.

Por otro lado, el extremo superior del comentado vástago 6 se remata en una cabeza 7' pasante a través de un orificio central 11 establecido al efecto en una especie de sombrerete 12 previsto superiormente y sobre el que va articulado un puente o semianilla 13, como elemento de enganche del dispositivo sobre un elemento 14, tal como un mosquetón o similar, previsto al efecto en el extremo inferior del cable 15 correspondiente a una grúa de manipu-
lación.On the other hand, the upper end of said rod 6 is finished off in a head 7 'through a central hole 11 established for this purpose in a kind of cap 12 provided above and on which a bridge or half-ring 13 is articulated, as hooking element of the device on an element 14, such as a carabiner or the like, provided for that purpose at the lower end of the cable 15 corresponding to a handling crane
lotion

De acuerdo con estas características, la forma de efectuar o llevar a cabo el enganche/desenganche del aludido dispositivo respecto de un molde o funda 16 para la formación de pilares es como sigue:According to these characteristics, the form of carry out or carry out the coupling / disengagement of the aforementioned device with respect to a mold or sheath 16 for the formation of Pillars is as follows:

Teniendo en cuenta que el molde o funda 16 se forma mediante la disposición perpendicular entre sí de cuatro paneles como se representa en la figura 3, para formar un cuerpo hueco prismático cuadrangular o rectangular, o incluso por dos paneles formados cada uno de ellos en ángulo o incluso para formar un molde cilíndrico en cuyo caso estaría formado por dos paneles semicilíndricos, se decía que el molde o funda 16, sea cual sea su configuración, presenta unas alas laterales y longitudinales 17 que sobresalen respecto del cuerpo tubular 16, y cuyas alas están afectadas de orificios 18 mediante los cuales se va a conseguir la fijación del dispositivo respecto del molde 16, teniendo en cuenta que éste quedará suspendido de dos elementos de enganche como el descrito en dos puntos opuestos, es decir en dos alas 17, por lo que la grúa tendrá dos cables de suspensión y cada uno de ellos vinculado a un dispositivo a través del elemento de enganche 14 como se decía con
anterioridad.Taking into account that the mold or sheath 16 is formed by the perpendicular arrangement of four panels perpendicularly to each other as shown in Figure 3, to form a quadrangular or rectangular hollow prismatic body, or even by two panels each formed at an angle or even to form a cylindrical mold in which case it would be formed by two semi-cylindrical panels, it was said that the mold or sheath 16, whatever its configuration, has lateral and longitudinal wings 17 that protrude with respect to the tubular body 16, and whose wings they are affected by holes 18 by means of which the device is to be fixed with respect to the mold 16, taking into account that it will be suspended from two hooking elements as described in two opposite points, that is to say in two wings 17, so that the crane will have two suspension cables and each of them linked to a device through the coupling element 14 as it was said with
anteriority.

Pues bien, a partir de lo comentado, lo primero que se hace es situar el dispositivo a través de su abertura 1 en correspondencia con el canto que define una de las alas laterales 17 del molde 16, efectuándose en primer lugar la ubicación del tetón 4 correspondiente al ala o extensión 3' del ala 3, en uno de los orificios 18 del ala 17 del molde 16, para después efectuar un giro del dispositivo sobre ese ala 17, hasta que el canto de ésta quede perfectamente ubicado en la abertura lateral 1 del cuerpo del dispositivo, efectuándose seguidamente un accionamiento manual del vástago 6, a través del brazo lateral 9 del mismo, para hacer descender tal vástago 6 a través de la ventana o ranura 10 y posicionar tal brazo 9 en la escotadura 8, reteniéndose en ésta, y por lo tanto retraído el vástago 6 en contra de la acción del resorte o muelle 7, todo ello de manera tal que el extremo libre de ese vástago 6 quedará alojado en los orificios enfrentados 8' de las alas 2 y 3 y a su vez pasante por uno de los orificios 18 del ala correspondiente 17 del molde 16, con lo que el dispositivo de enganche queda perfectamente enclavado al ala 17 y por lo tanto al molde 16, de modo que con dos elementos de enganche como se decía con anterioridad se consigue a través del accionamiento de la grúa y mediante su cable o cables 15, izar el molde 16 de forma segura y eficaz, de manera que para llevar a cabo el desenganche no hace falta que el operario tenga a mano el molde 16, sino que basta con un útil alargado 19, como se representa en la figura 6, a modo de pértiga o similar rematada en un elemento 20 a modo de anillo o similar que permita su enganche del brazo 9 con su acodamiento 9', traccionado éste hacia abajo para conseguir girar tal brazo 9 y posicionarlo de nuevo en su ventana o ranura 10, dejándolo en tal situación ya que el resorte o muelle 7 tiende a elevar el pasador o vástago 6 y por lo tanto a liberarse de los orificios 8' y 18 anteriormente referidos, quedando así liberado el dispositivo respecto del ala 17 del molde 16.Well, from the comments, the first that is done is to place the device through its opening 1 in correspondence with the song that defines one of the lateral wings 17 of the mold 16, the location of the pin 4 corresponding to the wing or extension 3 'of wing 3, in one of the holes 18 of the wing 17 of the mold 16, to then make a rotation of the device on that wing 17, until the edge of it is perfectly located in the lateral opening 1 of the body of the device, then a manual operation of the stem 6, through the side arm 9 thereof, to make lowering such a rod 6 through the window or slot 10 and position such arm 9 in the recess 8, retaining it, and therefore the rod 6 retracted against the action of the spring or spring 7, all in such a way that the free end of that rod 6 will be housed in the opposite holes 8 'of wings 2 and 3 and in turn through one of the holes 18 of the corresponding wing 17 of the mold 16, whereby the device hitch is perfectly locked to wing 17 and therefore to mold 16, so that with two coupling elements as stated previously it is achieved through the crane drive and using its cable or cables 15, hoist the mold 16 securely and effective, so that to carry out the release does not it is necessary that the operator has mold 16 on hand, but it is enough with an elongated tool 19, as shown in Figure 6, by way of pole or similar finished off in an element 20 as a ring or similar that allows your arm 9 to be engaged with its 9 'bend, pulled this one down to get to turn such arm 9 and position it again in its window or slot 10, leaving it in such situation since the spring or spring 7 tends to raise the pin or stem 6 and therefore to be released from holes 8 'and 18 previously referred to, thus releasing the device with respect to wing 17 of mold 16.
