DESCRIPCIONDESCRIPTION

OBJETO DE LA INVENCIONOBJECT OF THE INVENTION

La presente invention se encuadra en el campo tecnico de los puentes-grua que comprenden una o mas vigas principales sensiblemente horizontales, y se refiere en particular a un puente- grua dotado de una caja de cadenas y un mecanismo elevador moviles para ampliar la superficie de trabajo cubierta por la cadena, que encuentra especial aplicacion, aunque no se limita a dicho campo, en el interior de espacios de reducidas dimensiones, como por ejemplo las gondolas de aerogeneradores.The present invention falls within the technical field of crane bridges comprising one or more substantially horizontal main beams, and refers in particular to a crane bridge equipped with a box of chains and a mobile lifting mechanism to extend the surface of work covered by the chain, which finds special application, although not limited to this field, inside small spaces, such as wind turbine gondolas.

ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION

El puente grua es un dispositivo de elevation compuesto por una viga, simple o doble, que apoya o bien sobre dos carriles elevados sobre unos postes, o bien sobre los propios componentes de la edification, y un mecanismo elevador o grua, montada sobre un carro que desplaza a lo largo de dicha viga, en lo que se denomina camino de rodadura. A diferencia de las gruas moviles empleadas en construction, los puentes grua son empleados generalmente en instalaciones fijas para movilizar cargas elevadas tanto en sentido horizontal como en vertical dentro de la propia instalacion.The bridge crane is a lifting device composed of a beam, single or double, that supports either on two raised rails on posts, or on the building's own components, and a lifting or crane mechanism, mounted on a carriage which moves along said beam, in what is called the rolling path. Unlike mobile cranes used in construction, crane bridges are generally used in fixed installations to mobilize high loads both horizontally and vertically within the facility itself.

Dentro de los parametros fundamentales a determinar en un puente grua, se conoce como luz total a la distancia maxima horizontal entre los apoyos de la viga, mientras que la luz util es la distancia maxima horizontal entre el eje del camino de rodadura mas proximo al apoyo y el eje del elemento de prension, en este caso la cadena y el gancho de la grua, emplazado sobre la viga.Within the fundamental parameters to be determined in a crane bridge, it is known as total light at the maximum horizontal distance between the supports of the beam, while the useful light is the maximum horizontal distance between the axis of the raceway closest to the support and the axis of the clamping element, in this case the chain and the crane hook, located on the beam.

Los carros comprenden unos elementos de seguridad destinados a evitar su desplazamiento hasta los respectivos extremos finales de la viga, que generalmente consisten en unos brazos retenedores que, a modo de tope, impiden su acercamiento hasta dicho extremo y retienen al carro, y al mecanismo elevador montado sobre el, en una position lo suficientemente alejada de dichos extremos finales. Dicha posicion reduce en gran medida el espacio util de trabajo deThe carriages comprise safety elements intended to prevent their movement to the respective end ends of the beam, which generally consist of retaining arms that, as a stop, prevent their approach to said end and retain the carriage, and the lifting mechanism mounted on it, in a position far enough away from said endpoints. This position greatly reduces the useful working space of

espacios reducidos con entornos irregulares, como por ejemplo sucede en el interior de las gondolas de aerogeneradores.small spaces with irregular environments, such as inside the wind turbine gondolas.

DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION

El objeto de la invention consiste en un puente grua con capacidad de giro y desplazamiento de determinados elementos, concretamente la caja contendora de cadenas y el mecanismo elevador, lo que aumenta la luz util de trabajo de su cadena en hasta un 20% respecto de los puentes-gruas convencionales, haciendolo especialmente aplicable en espacios de reducidas dimensiones, aunque sin limitarse a dicho tipo de espacios. Una realization preferente del puente grua esta concebida para ser instalada de forma permanente en el interior de gondolas de aerogeneradores, que en los casos de aquellas mas grandes tienen unas dimensiones aproximadas de 8 metros de ancho, 14 metros de largo y 8 metros de altura.The object of the invention consists of a crane bridge with the ability to turn and displace certain elements, specifically the chain containing box and the lifting mechanism, which increases the useful working light of its chain by up to 20% with respect to conventional bridge-cranes, making it especially applicable in small spaces, although not limited to such spaces. A preferred embodiment of the crane bridge is designed to be permanently installed inside wind turbine gondolas, which in the cases of larger ones have approximate dimensions of 8 meters wide, 14 meters long and 8 meters high.

El puente grua giratorio comprende por una viga, preferentemente una viga doble, fijada por sus respectivos extremos a una estructura, por la cual desplazan longitudinalmente un carro, un mecanismo elevador tipo grua vinculado superiormente al carro, y una caja de cadenas vinculada inferiormente a dicho carro, en una position inferior a la viga y desplazada respecto a un eje longitudinal central del carro y el mecanismo elevador.The rotating crane bridge comprises a beam, preferably a double beam, fixed at their respective ends to a structure, by which they move a carriage longitudinally, a crane-type lifting mechanism linked superiorly to the carriage, and a chain box linked inferiorly to said carriage. carriage, in a position inferior to the beam and displaced with respect to a central longitudinal axis of the carriage and the lifting mechanism.

Para permitir el acercamiento de la cadena, y del gancho vinculado a dicha cadena, a los respectivos extremos finales de la viga, aumentando de esa manera su espacio util de trabajo, en primer lugar se disponen todos los componentes del mecanismo de elevation sobre una base o plataforma, la cual es desplazable giratoriamente sobre un cojinete de rodadura definido en el carro sobre el que apoya el mecanismo de elevacion que desplaza longitudinalmente a lo largo de la viga.In order to allow the chain, and the hook linked to said chain, to the respective end ends of the beam, thereby increasing its useful working space, first all the components of the lifting mechanism are arranged on a base or platform, which is rotatably movable on a rolling bearing defined in the car on which the lifting mechanism that moves longitudinally along the beam rests.

En segundo lugar, la caja de cadenas es desplazable lateralmente respecto al carro. Para ello, dicha caja de cadenas se vincula inferiormente al carro mediante unos medios de union liberables, siendo preferentemente dichos medios de union un brazo liberable, dotados de unos medios de fijacion que vinculan a los medios de union con un punto de fijacion definido en el carro, lo que permite un desplazamiento longitudinal de la caja de cadenas, hasta situarse a la derecha del carro, momento en que los medios de fijacion fijan la posicion de la caja de cadenas respecto al carro.Second, the chain box is laterally movable relative to the car. To this end, said chain box is inferiorly linked to the carriage by means of releasable joining means, said joining means being preferably a releasable arm, provided with fixing means that link the joining means with a fixing point defined in the carriage, which allows a longitudinal displacement of the chain box, until it is located to the right of the car, at which point the fixing means fix the position of the chain box with respect to the car.

Todos los movimientos anteriormente descritos son susceptibles de automatizarse y ser gobernados desde una unidad de control externa.All the movements described above are capable of being automated and governed from an external control unit.

Seguidamente se proporciona, con ayuda de las figuras anteriormente referidas, una explication detallada de un ejemplo de realization preferente del objeto de la presente invention.Next, a detailed explanation of an example of preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.

El puente grua giratorio que se describe, mostrado en las figuras 1 y 2, esta conformado por una viga (1) doble, fijada por sus respectivos extremos a una estructura, por la que desplazan longitudinalmente un carro (2), un mecanismo elevador (3) tipo grua vinculado superiormente al carro (2), y una caja de cadenas (4) vinculada inferiormente a dicho carro (2). Como puede observarse en dichas figuras, la caja de cadenas (4) se situa en una position inferior a la vigaThe rotating crane bridge described, shown in figures 1 and 2, is formed by a double beam (1), fixed at their respective ends to a structure, by which they move a carriage (2) longitudinally, a lifting mechanism ( 3) crane type linked superiorly to the carriage (2), and a chain box (4) inferiorly linked to said carriage (2). As can be seen in these figures, the chain box (4) is located in a position lower than the beam

(I) y desplazada respecto a un eje longitudinal central del carro (2) y el mecanismo elevador (3).(I) and displaced with respect to a central longitudinal axis of the carriage (2) and the lifting mechanism (3).

La caja de cadenas (4), mostrada en la figura 3, desplaza longitudinalmente a lo largo del extremo inferior de la viga (1), por rodadura de unas primeras ruedas (5) por unos patines inferiores de dicha viga (1), de los cuales se suspenden. Dicha caja de cadenas (4) comprende una carcasa (6) de geometrla esencialmente paralelepipedica e interior hueco, destinada a alojar una cadena (7) del mecanismo elevador (3), la cual es extralda de dicha carcasa (6) a traves de una abertura (8) definida en una cara superior.The chain box (4), shown in Figure 3, travels longitudinally along the lower end of the beam (1), by rolling first wheels (5) by lower skates of said beam (1), of which are suspended. Said chain box (4) comprises a housing (6) of essentially parallelepipedic geometry and hollow interior, intended to accommodate a chain (7) of the lifting mechanism (3), which is removed from said housing (6) through a opening (8) defined on an upper face.

Esta caja de cadenas (4) se vincula al carro (2) a traves de unos medios de union (9), que en esta realizacion preferente son un brazo liberable, fijado por uno de sus extremos a una gula (10) definida en la superficie de la carcasa (6) y vinculado por su otro extremo a un punto de fijacion (11) del carro (2), a traves de unos medios de fijacion (12), que en este caso son un posicionador de muelle roscado. La caja de cadenas (4) comprende adicionalmente una pluralidad de asideros (13) definidos en la superficie externa de la carcasa (6).This box of chains (4) is linked to the carriage (2) through means of union (9), which in this preferred embodiment are a releasable arm, fixed at one of its ends to a glutton (10) defined in the surface of the housing (6) and linked at its other end to a fixing point (11) of the carriage (2), through fixing means (12), which in this case are a threaded spring positioner. The chain box (4) additionally comprises a plurality of handles (13) defined on the outer surface of the housing (6).

El carro (2), ilustrado en la figura 4, desplaza longitudinalmente a lo largo del extremo superior de la viga (1), por rodadura de unas segundas ruedas (14) por unas cabezas superiores de dicha viga (1), sobre las cuales apoyan. Dicho carro (2) comprende una base (15) esencialmente paralelepipedica y plana, con una cara inferior a la que se vinculan las segundas ruedas (14) y un motor (16), y una cara superior desde la que se proyectan el punto de fijacionThe carriage (2), illustrated in Figure 4, moves longitudinally along the upper end of the beam (1), by rolling of second wheels (14) by upper heads of said beam (1), on which support Said carriage (2) comprises an essentially parallel and flat base (15), with a lower face to which the second wheels (14) and a motor (16) are linked, and an upper face from which the point of projecting is projected. fixation

Un orificio (18) pasante de geometria esencialmente circular, definido en la parte central de la base (15), conecta sus caras superior e inferior. En el borde longitudinal de dicho orificio (18) se fija un cojinete (19) de rodadura elaborado en teflon.An orifice (18) of essentially circular geometry, defined in the central part of the base (15), connects its upper and lower faces. A rolling bearing (19) made of teflon is fixed on the longitudinal edge of said hole (18).

El mecanismo elevador (3), como se observa en la figura 5, comprende en primer lugar un soporte (20) de geometria y dimensiones esencialmente similares a las del cojinete (19) del carro (2), con el cual esta destinado a vincularse. Dicho soporte (20) comprende asimismo una cara superior, una cara inferior y un orificio central pasante.The lifting mechanism (3), as seen in Figure 5, first comprises a support (20) of geometry and dimensions essentially similar to those of the bearing (19) of the carriage (2), with which it is intended to be linked . Said support (20) also comprises an upper face, a lower face and a through central hole.

De la cara superior del soporte (20) parte superiormente el dispositivo de izado, compuesto por un motor de izado (21) y un carrete (22) sobre cuya superficie se arrolla la cadena (7). Tambien se proyectan hacia la parte superior del soporte (20) una pluralidad de asas (23), uniformemente distribuidas por el borde exterior de dicha cara superior, y unas argollas (17) pivotantes similares a las dispuestas en la cara superior del carro (2). Asimismo, un brazo fijo (24) que parte lateralmente del soporte (20) limita el desplazamiento del mecanismo elevador (3) y el carro (2) al que se vincula a lo largo del camino de rodadura sobre la viga (1) para evitar impactos del soporte (20) y sus elementos con los extremos de dicha viga (1) y de la estructura en la que se sustenta, al llegar al final del camino de rodadura.From the upper face of the support (20) the lifting device is upper part, composed of a lifting motor (21) and a reel (22) on whose surface the chain (7) is wound. A plurality of handles (23), evenly distributed along the outer edge of said upper face, and pivoting rings (17) similar to those arranged on the upper face of the carriage (2) are also projected towards the upper part of the support (20). ). Also, a fixed arm (24) that laterally part of the support (20) limits the displacement of the lifting mechanism (3) and the carriage (2) to which it is linked along the raceway on the beam (1) to avoid impacts of the support (20) and its elements with the ends of said beam (1) and the structure on which it is supported, upon reaching the end of the road.

La cadena (7), comprende un primer extremo vinculado al carrete (22) y un segundo extremo libre al que se une un gancho (25) para vinculacion con los elementos a desplazar por parte del mecanismo elevador (3). Dicha cadena (7) desplaza longitudinalmente en movimiento ascendente o descendente atravesando el espacio comprendido entre los dos cuerpos que constituyen la viga (1) doble, en funcion de las ordenes enviadas por un dispositivo de mando externo, no representado en las figuras adjuntas. Como si puede observarse en dichas figuras, la cadena (7) tiene una disposition excentrica respecto al eje longitudinal central del carro (2) y el mecanismo elevador (3).The chain (7), comprises a first end linked to the reel (22) and a second free end to which a hook (25) is attached to link with the elements to be displaced by the lifting mechanism (3). Said chain (7) moves longitudinally in upward or downward movement through the space between the two bodies that constitute the double beam (1), depending on the orders sent by an external control device, not shown in the attached figures. As can be seen in said figures, the chain (7) has an eccentric arrangement with respect to the central longitudinal axis of the carriage (2) and the lifting mechanism (3).

Una manguera (26) flexible, de geometria esencialmente cillndrica e interior hueco contiene y protege el cableado necesario para el funcionamiento del puente grua. Dicha manguera (26) discurre entre las respectivas argollas (17) del carro (2) y el mecanismo elevador (3). Se contempla asimismo la incorporation de una pluralidad de sensores (27) dispuestos tanto en el carro (2), como en el mecanismo elevador (3) y en la caja de cadenas (4) que envlan information acerca de la position de dichos elementos a una caja de sensores (28) dispuesta en uno de los extremos finales de la viga (1).A flexible hose (26) of essentially cylindrical geometry and hollow interior contains and protects the wiring necessary for the operation of the crane bridge. Said hose (26) runs between the respective rings (17) of the carriage (2) and the lifting mechanism (3). It is also contemplated the incorporation of a plurality of sensors (27) arranged both in the carriage (2), as in the lifting mechanism (3) and in the chain box (4) that send information about the position of said elements to a sensor box (28) arranged at one of the end ends of the beam (1).

En las figuras 6 y 7 se muestran dos vistas del carro (2) y el mecanismo elevador (3) montado sobre dicho carro (2) dispuestos al final del camino de rodadura, proximos al extremo final de la viga (1) en el que se dispone la caja de sensores (28). Como puede observarse en dichas figuras, el voladizo util de la cadena (7) se ve reducido en una distancia marcada en la figura 6 5 como "a”, distancia en la cual dicha cadena (7) no alcanza para transportar ninguna carga.Figures 6 and 7 show two views of the carriage (2) and the lifting mechanism (3) mounted on said carriage (2) arranged at the end of the raceway, near the end of the beam (1) in which the sensor box (28) is arranged. As can be seen in said figures, the useful overhang of the chain (7) is reduced by a distance marked in Figure 6 5 as "a", distance in which said chain (7) is not enough to transport any cargo.

En las figuras 8 y 9 se muestran otras dos vistas del carro (2) y el mecanismo elevador (3) en el mismo extremo de la viga (1), en una position en la cual el voladizo util de la cadena (7) se ve reducido en una distancia marcada como “b”, que como se aprecia es inferior a la distancia "a” 10 anterior. El paso de una posicion a otra aumenta por tanto el voladizo o espacio de trabajo util de la cadena (7), lo cual redunda beneficiosamente en la operatividad del puente grua.Figures 8 and 9 show two other views of the carriage (2) and the lifting mechanism (3) at the same end of the beam (1), in a position in which the useful overhang of the chain (7) is is reduced by a distance marked "b", which, as seen, is less than the distance "a" 10 above. The passage from one position to another therefore increases the overhang or useful working space of the chain (7), which beneficially results in the operation of the crane bridge.

Dicho cambio de posicion se debe tanto a un desplazamiento lateral de la caja de cadenas (4) como a un giro del mecanismo elevador (3) respecto al carro (2). Para el desplazamiento de la 15 caja de cadenas (4), cuya secuencia se muestra en la figura 10, en primer lugar se sueltan los medios de fijacion (12) que fijan a los medios de union (9) en el punto de fijacion (11) del carro (2), lo que permite un desplazamiento longitudinal de la caja de cadenas (4), que sigue vinculada a los medios de union (9) por la gula (10) de su carcasa (6), hasta situarse a la derecha del carro (2), en una posicion simetrica a la inicial, momento en que los medios de 20 fijacion (12) se vinculan de nuevo al punto de fijacion (11), para fijar la posicion de la caja de cadenas (4) respecto al carro (2).Said position change is due both to a lateral displacement of the chain box (4) and to a rotation of the lifting mechanism (3) with respect to the carriage (2). For the displacement of the chain box (4), the sequence of which is shown in Figure 10, firstly the fixing means (12) that fix the joining means (9) at the fixing point () are released. 11) of the carriage (2), which allows a longitudinal displacement of the chain box (4), which is still linked to the joining means (9) by the glutton (10) of its housing (6), until it reaches the right of the carriage (2), in a symmetrical position to the initial one, at which time the fixing means (12) are linked again to the fixing point (11), to fix the position of the chain box (4 ) with respect to the car (2).

Por otro lado, el mecanismo elevador (3) puede desplazarse sobre el carro (2), girando 180° para pasar de la posicion mostrada en la figura 7 a la de la figura 9, y asl acercar la cadena (7) 25 y el gancho (25) a una posicion mas proxima al extremo de la viga (1) y de esa manera aumentar su espacio util de trabajo. Para ello, tomandolo de las asas (23), se hace girar el soporte (20) de dicho mecanismo elevador (3) en el interior del cojinete (19) 180°, hasta alcanzar la posicion deseada. El cableado contenido en la manguera (26) acompana al giro del mecanismo elevador (3) respecto al carro (2) gracias a la capacidad pivotante de las argollas 30 (17) fijadas en ambos elementos.On the other hand, the lifting mechanism (3) can move on the carriage (2), rotating 180 ° to move from the position shown in Figure 7 to that of Figure 9, and thus bring the chain (7) 25 and the hook (25) to a position closer to the end of the beam (1) and thereby increase its useful working space. To do this, taking it from the handles (23), the support (20) of said lifting mechanism (3) is rotated inside the bearing (19) 180 °, until reaching the desired position. The wiring contained in the hose (26) accompanies the rotation of the lifting mechanism (3) with respect to the carriage (2) thanks to the pivoting capacity of the rings 30 (17) fixed in both elements.
