GRUA PARA MANIPULACION DE CONTENEDORESCRANE FOR CONTAINER HANDLING
DESCRIPCIONDESCRIPTION
OBJETO DE LA INVENCIONOBJECT OF THE INVENTION
La presente invencion se refiere a una grua para la manipulacion de contenedores, en concreto, la presente invencion se refiere a un accesorio acoplable a una grua que permite la manipulacion de contenedores cuyas medidas no son estandar.The present invention refers to a crane for the handling of containers, in particular, the present invention refers to an attachment that can be attached to a crane that allows the handling of containers whose measures are not standard.
La presente invencion es aplicable tanto a gruas de portico como a las gruas moviles autopropulsadas portacontenedores del tipo conocido en la tecnica.The present invention is applicable to both gantry cranes as well as self-propelled mobile container cranes of the type known in the art.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
Son conocidos diversos tipos de gruas para la manipulacion de contenedores, en terminos generales se puede decir que, si las dividimos en el tipo de mecanismo utilizado para levantar los contenedores, existen dos tipos de gruas: las que cuentan con un sistema de bayoneta en el que la bayoneta se introduce en la parte superior del contenedor adaptada para recibir dicha bayoneta y mediante un sistema de bloqueo por rotacion (o twistlock, por su denomination en ingles) fija el contenedor a la grua, lo que permite levantarlo y manipularlo; o las que cuentan con un sistema de pinzas en el que las pinzas se extienden por los laterales del contenedor y sujetan al contenedor por su parte inferior.Various types of cranes are known for the handling of containers, in general terms it can be said that, if we divide them into the type of mechanism used to lift the containers, there are two types of cranes: those with a bayonet system in the that the bayonet is inserted in the upper part of the container adapted to receive said bayonet and by means of a system of blocking by rotation (or twistlock, by its denomination in English) fixes the container to the crane, which allows it to be lifted and manipulated; or those that have a gripper system in which the clips extend along the sides of the container and hold the container at its bottom.
En aplicaciones que requieren una rapida operation de carga y descarga de contenedores es preferible el uso del sistema de sujecion por la parte superior del contenedor ya que es mas rapida y no requiere acceso a la parte inferior del contenedor que, normalmente, es de dificil acceso.In applications that require a fast loading and unloading operation of containers, it is preferable to use the upper part of the container as it is faster and does not require access to the lower part of the container, which is usually difficult to access .
Uno de los problemas que poseen las gruas con el sistema de manipulacion por bayoneta es que, se necesita algun tipo de mecanismo que permita realizar un alineamiento entre la bayoneta y el contenedor. Para solucionar este problema, las gruas cuentan con un sistema de aletas (o flippers, por su denomination en ingles) que permiten centrar el contenedor y, en consecuencia, alinear la bayoneta con el contenedor. Normalmente estas aletas se encuentran ubicadas en los spreader y es habitual encontrarlas tanto en las gruas como en las carretillas portico para el traslado de contenedores.One of the problems that the cranes have with the bayonet manipulation system is that some type of mechanism is needed to make a alignment between the bayonet and the container. To solve this problem, the cranes have a system of fins (or flippers, by their denomination in English) that allow to center the container and, consequently, align the bayonet with the container. Normally these fins are located in the spreaders and it is common to find them both in the cranes and in the portico trucks for the transfer of containers.
Sin embargo, uno de los requerimientos para que este arreglo spreader-aleta funcione correctamente es que la aleta se extienda a una distancia transversal del spreader que, por una parte, permita acceder al lateral del contenedor y, por otra parte, este lo suficientemente cerca al mismo como para poder ejercer un centrado entre la bayoneta y el punto de levantamiento del contenedor. En consecuencia, la distancia axial que separa la aleta del spreader es una distancia fija y esta pre-definida lo que limita esta solution a un tipo de contenedor con unas medidas determinadas.However, one of the requirements for this spreader-fin arrangement to work properly is that the fin extends to a transversal distance of the spreader that, on the one hand, allows access to the side of the container and, on the other hand, is close enough to the same as to be able to exert a centering between the bayonet and the lifting point of the container. Consequently, the axial distance separating the fin from the spreader is a fixed distance and it is pre-defined, which limits this solution to a type of container with certain dimensions.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
Es un objetivo de la presente invention dar a conocer un tipo de grua que permite solucionar los problemas de la tecnica anterior mediante la adicion de un mecanismo de configuration del tamano del contenedor a utilizar. Esto permite utilizar una misma grua para diferentes tamanos de contenedores agilizando, en consecuencia, las labores de movimiento de contenedores.It is an object of the present invention to provide a type of crane that allows to solve the problems of the prior art by adding a mechanism for configuring the size of the container to be used. This makes it possible to use the same crane for different sizes of containers, thus speeding up the movement of containers.
En concreto, la presente invencion da a conocer una grua para la manipulation de contenedores que comprende:In particular, the present invention discloses a crane for the manipulation of containers comprising:
• una cabina de control;• a control cabin;
• un spreader que comprende actuadores para su desplazamiento y medios de comunicacion con la cabina de control;• a spreader comprising actuators for its movement and means of communication with the control cabin;
• al menos una aleta acoplada a dicho spreader; y• at least one fin coupled to said spreader; Y
• una bayoneta que, a su vez, comprende un sistema de bloqueo por rotacion adaptada para acoplarse a la parte superior de un contenedor; en el que dicha aleta se extiende transversalmente a una distancia determinada del spreader. Ademas, la grua segun la presente invencion comprende un mecanismo de desplazamiento de la aleta en una direccion sustancialmente transversal respecto al spreader. Esta capacidad de desplazamiento de la aleta es lo que permite que la grua pueda alinearse, mediante una facil reconfiguration de las aletas, a diferentes tamanos de contenedores que es especialmente ventajoso, por ejemplo, en el caso de contenedores que disponen de un aislamiento termico que aumenta sus dimensiones. En concreto, la presente invencion comprende dos aletas acopladas al spreader.• a bayonet which, in turn, comprises a rotational locking system adapted to be coupled to the upper part of a container; wherein said fin extends transversely at a certain distance from the spreader In addition, the crane according to the present invention comprises a mechanism for moving the fin in a direction substantially transverse to the spreader. This ability to move the fin is what allows the crane to be aligned, through an easy reconfiguration of the fins, to different sizes of containers that is especially advantageous, for example, in the case of containers that have a thermal insulation that increases its dimensions. In particular, the present invention comprises two fins coupled to the spreader.
En una realization especialmente preferente, el mecanismo de desplazamiento de la aleta es un mecanismo hidraulico, por ejemplo, mediante cilindros hidraulicos. Adicionalmente, se podria contemplar que el mecanismo de desplazamiento de la aleta es un mecanismo electrico, por ejemplo mediante un solenoide.In a particularly preferred embodiment, the movement mechanism of the fin is a hydraulic mechanism, for example, by hydraulic cylinders. Additionally, it could be contemplated that the movement mechanism of the fin is an electrical mechanism, for example by means of a solenoid.
Opcionalmente, el desplazamiento de la aleta es un desplazamiento lineal y puede contar con diferentes posiciones predefinidas dependiendo del tamano de contenedor a manipular o puede dejarse a cargo de la cabina de control de determinar la magnitud de desplazamiento que se requiere para cada operacion.Optionally, the displacement of the fin is a linear displacement and can have different predefined positions depending on the size of the container to be manipulated or it can be left in charge of the control cabin to determine the amount of displacement that is required for each operation.
En cuanto al manejo de las partes de la grua, la presente invencion da a conocer una realizacion preferente en la que el mecanismo de desplazamiento de la aleta comprende medios de comunicacion con la cabina de control y, desde alli, se puede seleccionar una magnitud de desplazamiento predeterminada o se puede disponer de medios para que sea el operador el que determine la posicion optima para cada operation. Preferentemente la aleta dispone de dos posiciones, una para contenedores estandar y otra para contenedores con un ancho mayor (por ejemplo, debido a aislamientos termicos).As regards the handling of the parts of the crane, the present invention discloses a preferred embodiment in which the movement mechanism of the fin comprises means of communication with the control cabin and, from there, a magnitude of default displacement or means may be available for the operator to determine the optimal position for each operation. Preferably the fin has two positions, one for standard containers and another for containers with a wider width (for example, due to thermal insulation).
Adicionalmente, tal y como se ha mencionado anteriormente, la presente invencion es aplicable a cualquier tipo de grua para el manejo de contenedores, especialmente, gruas de portico y gruas moviles autopropulsadas portacontenedores. Additionally, as mentioned above, the present invention is applicable to any type of crane for handling containers, especially gantry cranes and self-propelled mobile containers cranes.

La figura 4 muestra en detalle la aleta del spreader de la figura 3.Figure 4 shows in detail the fin of the spreader of figure 3.
REALIZACION PREFERENTE DE LA INVENCIONPREFERRED EMBODIMENT OF THE INVENTION
La figura 1 muestra una grua segun la presente invencion, en concreto la grua (1) es una grua ubicada en un puerto para descargar contenedores (7) de un barco (5). La grua (1) cuenta con una torre (2), un mastil o pluma (4), una cabina de control (3) y sus respectivos contrapesos y contrapluma.Figure 1 shows a crane according to the present invention, in particular the crane (1) is a crane located in a port for unloading containers (7) of a ship (5). The crane (1) has a tower (2), a mast or boom (4), a control cabin (3) and its respective counterweights and counter-feather.
Adicionalmente, la grua comprende un mecanismo para la manipulacion de los contenedores, conocido en la tecnica como spreader (6). Este spreader (6) tiene la funcion de acoplarse a los contenedores por su parte superior para la manipulation de los mismos. Existen otro tipo de elementos para dicho acople a los contenedores, en concreto, las pinzas son un mecanismo ampliamente conocido y utilizado en ciertos casos.Additionally, the crane comprises a mechanism for the manipulation of the containers, known in the art as spreader (6). This spreader (6) has the function of coupling to the containers by its upper part for the manipulation of the same. There are other types of elements for this coupling to containers, in particular, the clamps are a widely known mechanism and used in certain cases.
A diferencia de las pinzas, el spreader tiene unas ventajas considerables al manipular el contenedor por la parte superior entre las que destacan:Unlike the clamps, the spreader has considerable advantages when handling the container at the top, among which are:
• Mayor seguridad en las operaciones ya que en las pinzas existe el riesgo de deslizamiento a traves de las mismas• Greater safety in operations since in the grippers there is a risk of sliding through them
• Evita desperfectos por abolladuras y/o perforaciones en los contenedores por accion de las pinzas.• It avoids damage by dents and / or perforations in the containers by the action of the clamps.
• Permite manipular contenedores apilados y/o aplicar contenedores que en el caso de las pinzas es mas complejo ya que se debe acceder a la parte inferior del contenedor para su manipulacion.• It allows to manipulate stacked containers and / or to apply containers that in the case of the tweezers is more complex since it is necessary to access the lower part of the container for its manipulation.
La figura 2A muestra un caso tipico de como se acopla un contenedor (7) de tamano estandar a un spreader (6). En el caso habitual, el spreader comprende una aleta (63) (o flipper, como se denomina esta pieza en ingles) cuya funcion es centrar el contenedor y servir como guia para que una bayoneta entre en contacto con la cantonera (72) del contenedor del tipo conocido, por ejemplo, en ISO1161. En definitiva la aleta (63) se mueve una trayectoria (71) entrando en contacto con el lateral del travesano del contenedor (7) para su alineacion. Una vez la bayoneta pasa a traves de la cantonera (72), mediante un sistema de bloqueo por rotation, el contendor (7) queda acoplado al spreader (6). En las gruas de la tecnica anterior, la aleta (63) se encuentra a una distancia fija de la bayoneta (64). Es importante destacar que algunas gruas (1) cuentan con aletas abatibles de manera que, cuando estan en uso, la distancia con la bayoneta (64) es fija y cuando estan abatidas simplemente no se utilizan para centrar el contenedor (7), cuando en la presente invention se menciona que las aletas (63) se mantienen a una distancia fija de la bayoneta (64) debe interpretarse que esta distancia es fija cuando la aleta (63) esta en uso. Figure 2A shows a typical case of how a container (7) of standard size is coupled to a spreader (6). In the usual case, the spreader comprises a fin (63) (or flipper, as this piece is called in English) whose function is to center the container and serve as a guide for a bayonet to come into contact with the butt plate (72) of the container of the type known, for example, in ISO1161. In short, the fin (63) moves a path (71) coming into contact with the side of the crossbar of the container (7) for alignment. Once the bayonet passes through the butt plate (72), by means of a rotation blocking system, the container (7) is coupled to the spreader (6). In the cranes of the prior art, the fin (63) is at a fixed distance from the bayonet (64). It is important to note that some cranes (1) have folding flaps so that, when they are in use, the distance with the bayonet (64) is fixed and when they are down simply are not used to center the container (7), when in The present invention mentions that the fins (63) are held at a fixed distance from the bayonet (64). It should be interpreted that this distance is fixed when the fin (63) is in use.
En el caso de la figura 2B, se muestra que un sistema spreader-aleta convencional tiene un problema cuando se trata de manipular contenedor cuya anchura excede, aunque sea por un pequeno margen, la anchura convencional.In the case of Figure 2B, it is shown that a conventional spreader-fin system has a problem when it comes to handling container whose width exceeds, even by a small margin, the conventional width.
En este caso concreto, se observa claramente que al mover el spreader a lo largo de la trayectoria (71) la aleta no podra centrar el contenedor para permitir el contacto entre la bayoneta (64) y los agujeros de sujecion (71) del contenedor (7). En este caso ejemplar el contenedor es un contenedor frigorifico que tiene una anchura dFRiG diferente de la anchura dsTD del contenedor estandar de la figura 2A.In this particular case, it is clearly observed that by moving the spreader along the path (71) the fin will not be able to center the container to allow contact between the bayonet (64) and the fastening holes (71) of the container ( 7). In this exemplary case the container is a refrigerated container having a width dFRiG different from the width dsTD of the standard container of Figure 2A.
Esta pequena diferencia de anchura d evita la manipulacion del contenedor mediante un spreader por lo que, en la tecnica anterior, se tiene que desmontar la aleta, abatirla (en caso de spreader con aleta abatible) o cambiar el tipo de mecanismo de manipulacion a utilizar por otro como, por ejemplo, unas pinzas.This small difference in width d prevents handling of the container by means of a spreader, so in the prior art, the fin has to be disassembled, folded down (in the case of spreader with folding flap) or the type of handling mechanism to be used by another such as, for example, a pair of tweezers.
La figura 3 muestra un ejemplo de spreader (6) segun la presente invencion. En esta figura se muestra un spreader (6) que dispone de un par de vigas longitudinales (61) y un par de vigas transversales (62) aunque un experto en la materia entenderia que tambien es posible tener un unico bloque base que dispone de un eje longitudinal y un eje transversal en lugar de vigas independientes unidas entre si.Figure 3 shows an example of spreader (6) according to the present invention. This figure shows a spreader (6) that has a pair of longitudinal beams (61) and a pair of transverse beams (62) although an expert in the field would understand that it is also possible to have a single base block that has a longitudinal axis and a transverse axis instead of independent beams joined together.
A la base formada por las vigas longitudinales (61) y transversales (62) se encuentra unida al menos una aleta (63) y dicha base comprende, ademas una bayoneta (64) equipada con un mecanismo de bloqueo por rotacion. En una realization habitual de la presente invencion a la base se unen dos aletas.To the base formed by the longitudinal (61) and transverse (62) beams is attached at least one fin (63) and said base also comprises a bayonet (64) equipped with a rotation locking mechanism. In a usual embodiment of the present invention two fins are attached to the base.
La figura 4 muestra un detalle de la aleta (63) segun la presente invencion. Esta aleta comprende una guia (631) dispuesta para centrar el contenedor respecto al spreader, una placa (632) para la union de la aleta a la base (en este ejemplo concreto, a una de las vigas transversales (62)) y ademas dicha aleta (63) cuenta con un mecanismo de desplazamiento (633) de la aleta (63) en una direction sustancialmente transversal respecto a la base. Figure 4 shows a detail of the fin (63) according to the present invention. This fin comprises a guide (631) arranged to center the container with respect to the spreader, a plate (632) for joining the fin to the base (in this specific example, one of the transverse beams (62)) and also said fin (63) has a displacement mechanism (633) of the fin (63) in a direction substantially transverse to the base.
En una realization especialmente preferente, el mecanismo de desplazamiento (633) de la aleta (63) cuenta con dos posiciones, una para contenedores estandar y otra para contenedores con aislamiento termico. En este caso, la distancia a desplazar la aleta mediante el mecanismo de desplazamiento es una distancia d predeterminada y en la cabina de control solo existen dos posiciones: de aleta extendida o aleta en position estandar. Sin embargo, en otras realizaciones de la presente invention el mecanismo de desplazamiento puede contar de multiples posiciones o, incluso, puede contar de un sensor para la medicion de la distancia d de extension de la aleta y desde la cabina de control (3) se puede determinar la distancia que se requiere en cada caso.In a particularly preferred embodiment, the displacement mechanism (633) of the fin (63) has two positions, one for standard containers and another for containers with thermal insulation. In this case, the distance to move the fin by means of the displacement mechanism is a predetermined distance d and in the control cabin there are only two positions: extended fin or fin in standard position. However, in other embodiments of the present invention, the displacement mechanism may have multiple positions or may even count on a sensor for measuring the extension distance d of the fin and from the control cabin (3) it is You can determine the distance that is required in each case.
Si bien la invencion se ha descrito con respecto a ejemplos de realizaciones preferentes, estos no se deben considerar limitativos de la invencion, que se definira por la interpretacion mas amplia de las siguientes reivindicaciones Although the invention has been described with respect to examples of preferred embodiments, these should not be considered as limiting the invention, which will be defined by the broadest interpretation of the following claims
