Pinza-pulpo para elevación de cargas mejorada.Clamp-octopus for lifting Enhanced loads

Objeto de la invenciónObject of the invention

La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una pinza-pulpo para elevación de cargas mejorada que aporta a la función a que se destina una serie de ventajas y características perfeccionadas, que se describirán en detalle más adelante, y que suponen una innovadora mejora a lo ya conocido en este campo.The invention, as expressed in the statement of The present specification refers to a clamp-octopus for enhanced load lifting that brings to the function a series of advantages and perfected features, which will be described in more detail forward, and that represent an innovative improvement to what is already known in this field.

De forma más concreta, el objeto de la invención consiste en un mecanismo de pinza-pulpo o carramarro, de tres o más garras o palas, pensado tanto para elevación de masas (pinza), como por ejemplo bloques pétreos, de hormigón o similares, o bien materiales sueltos (pulpo), que resulta completamente distinto a todo lo anterior, estando mejorado con un sistema de bielas que permite el cierre cinemático del mecanismo y un sistema de largueros de arriostramiento que evitan la deformación del mecanismo, de forma que la posición de los diferentes elementos que comprende determinan un mejor trabajo y rendimiento de sus componentes.More specifically, the object of the invention It consists of a clamp-octopus mechanism or Carramarro, with three or more claws or blades, designed for both mass elevation (clamp), such as stone blocks, of concrete or similar, or loose materials (octopus), which It is completely different from all of the above, being improved with a crank system that allows the kinematic closure of the mechanism and a system of bracing stringers that prevent the deformation of the mechanism, so that the position of the different elements that you understand determine a better job and performance of its components.

Antecedentes de la invenciónBackground of the invention

En la actualidad, y como referencia al estado de la técnica, debe mencionarse, que los mecanismos, pinza o pulpo (también conocidos como carramarro), para el izado de cargas, accionados por gravedad, con más de dos garras o palas, presentan las siguientes características:Currently, and as a reference to the state of the technique, it should be mentioned, that the mechanisms, clamp or octopus (also known as carramarro), for lifting loads, gravity operated, with more than two claws or blades, present The following features:

Al disponer de más de dos garras o palas, presentan la posibilidad de que, en su funcionamiento normal, la sujeción de los materiales a elevar se realice únicamente mediante dos de las múltiples garras o palas. Esta situación, junto con la cadena cinemática de los mecanismos actuales, provoca un funcionamiento que sobrecarga las garras que trabajan en vacío, deformando el mecanismo y originando su rotura o mal funcionamiento.By having more than two claws or shovels, they present the possibility that, in their normal operation, the fastening of the materials to be lifted is done only by two of the multiple claws or shovels. This situation, along with the Kinematic chain of current mechanisms, causes a performance that overloads the claws that work in a vacuum, deforming the mechanism and causing its breakage or bad functioning.

El hecho de que una o varias garras trabaje en vacío, unido a la fuerte multiplicación en el tiro de aproximación entre núcleos (debido al aparejo de poleas), provoca una flexión secundaria en el plano perpendicular al de la cadena cinemática de cada uno de los brazos, afectando gravemente a las articulaciones y demás elementos que componen dicha cadena, o bien originando la sobrecarga y posible rotura de los brazos.The fact that one or more claws work in empty, together with the strong multiplication in the approach shot between cores (due to pulley rigging), causes flexion secondary in the plane perpendicular to that of the kinematic chain of each of the arms, severely affecting the joints and  other elements that make up this chain, or originating the overload and possible breakage of the arms.

La solución adoptada actualmente para evitar el fallo mencionado consiste en un sobredimensionado del mecanismo y sus componentes, articulaciones, brazos y bulones, de tal forma que los costes de manejo y explotación del mismo, debido a su elevado peso, se disparan con respecto a mecanismo de menor peso.The solution currently adopted to avoid mentioned failure consists of an oversized mechanism and its components, joints, arms and bolts, so that the costs of handling and exploitation of it, due to its high weight, they are triggered with respect to the mechanism of lower weight.

Cabe señalar, por otra parte, que la pinza-pulpo para elevación de cargas mejorada que la presente invención propugna presenta perfeccionamientos que lo dotan de características técnicas, estructurales y constitutivas innovadoras, que lo diferencian sustancialmente de los sistemas conocidos para el mismo fin, solucionando de forma práctica y efectiva la problemática anteriormente planteada.It should be noted, on the other hand, that the clamp-octopus for lifting loads better than the The present invention advocates improvements that they have technical, structural and constitutive characteristics innovative, which differentiate it substantially from systems known for the same purpose, solving in a practical way and effective the problem previously raised.

Explicación de la invenciónExplanation of the invention.

De forma concreta, la pinza-pulpo que la invención propugna, tanto por la geometría de su diseño y el de la cadena cinemática, como por la posición relativa de los elementos que lo componen, proporciona respecto a los mecanismos existentes las siguientes mejoras, utilidades y ventajas prácticas:Specifically, the clamp-octopus that the invention advocates, both for the geometry of its design and that of the kinematic chain, as per the relative position of the elements that compose it, provides respect to the mechanisms The following improvements, utilities and advantages exist practices:

El funcionamiento en las condiciones habituales de que sólo dos de las garras o palas sujeten la carga a elevar, y el resto trabajen en vacío o muy descargadas, es estable, compensando los esfuerzos de flexión secundaria mediante la estructura y cadena cinemática diseñadas, evitando la rotura o deformación prematura del mecanismo.Operation in the usual conditions that only two of the claws or blades hold the load to be lifted, and the rest work empty or heavily discharged, it is stable, compensating secondary bending efforts by kinematic structure and chain designed, avoiding breakage or premature deformation of the mechanism.

El diseño realizado, tanto de la estructura como de la cadena cinemática permiten que el peso del mecanismo resultante sea mucho menor que el de los mecanismos actualmente existentes a igualdad de capacidad de carga, lo cual conlleva unos costes de explotación y fabricación mucho menores.The design made, both of the structure and of the kinematic chain allow the weight of the mechanism resulting is much smaller than that of the mechanisms currently existing to equal load capacity, which entails some much lower operating and manufacturing costs.

La nueva pinza-pulpo para elevación de cargas mejorada representa, por consiguiente, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The new clamp-octopus for improved load lifting therefore represents a innovative structure of structural features and constitutives unknown so far for that purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.

Un cuerpo de poleas superior (2), consistente en un elemento que sirve de sujeción y alojamiento de las poleas superiores (3) del mecanismo así como de unión entre los brazos (4), que en un número variable y mayor de dos, se unen por un extremo a dicho cuerpo de poleas superior (2), y por el opuesto a largueros de arriostramiento.An upper pulley body (2), consisting of an element that serves as support and accommodation of the pulleys upper (3) of the mechanism as well as of union between the arms (4), which in a variable number and greater than two, are joined by a end to said upper pulley body (2), and the opposite of bracing stringers.

Dichos largueros de arriostramiento (5), en el mismo número que brazos (4), están unidos entre si en un mismo plano, formando un polígono, en cuyos vértices se unen los brazos (4) en su extremo inferior, tal como se ha mencionado, y se disponen articulaciones por medio de bulones (6) en las que se conectan las garras (7) de la pinza o las palas del pulpo o carramarro según el caso.These bracing stringers (5), in the same number as arms (4), are joined together in the same plane, forming a polygon, in whose vertices the arms join (4) at its lower end, as mentioned, and it they have joints by means of bolts (6) in which connect the claws (7) of the clamp or the octopus blades or carramarro according to the case.

En la figura 2, se aprecia como bajo el descrito bastidor (1), la pinza-pulpo dispone de un cuerpo de poleas inferior (8), consistente en un elemento que sirve de sujeción y alojamiento de las poleas inferiores (9), y al cual se unen, igualmente mediante articulación por bulones (10), bielas biarticuladas (11) en número igual al de brazos (4).In Figure 2, it can be seen as described below. frame (1), the clamp-octopus has a body of lower pulleys (8), consisting of an element that serves as clamping and accommodation of the lower pulleys (9), and to which join, also by articulation by bolts (10), connecting rods biarticulated (11) in number equal to that of arms (4).

Estas bielas (11) a su vez se encuentran unidas por su parte inferior, mediante articulación por bulones (12), a las garras o palas (7), tal como puede apreciarse en las figuras 3 y 4.These cranks (11) in turn are attached by its lower part, by articulation by bolts (12), to the claws or blades (7), as can be seen in figures 3 and 4.

Las poleas superiores (3) e inferiores (9), alojadas respectivamente en el cuerpo superior (2) e inferior (8), se enlazan mediante cableado (13) que movido externamente accionará el mecanismo para su apertura y cierre, siendo el funcionamiento de dicho mecanismo accionado por gravedad provocando su acercamiento o alejamiento, tal como se aprecia en las figuras 3 y 4.The upper (3) and lower pulleys (9), housed respectively in the upper (2) and lower (8) body, are linked by wiring (13) that externally moved will trigger the mechanism for opening and closing, being the operation of said gravity actuated mechanism causing its approach or distance, as shown in figures 3 and 4.

Visto lo anterior, se puede apreciar como el sistema de bielas (11) permite ventajosamente el cierre cinemático del mecanismo, mientras los largueros de arriostramiento (5) evitan su deformación aún cuando sólo trabajen dos de las garras o palas (7), determinándose un mejor trabajo y rendimiento de todos los componentes de la pinza-pulpo.Given the above, it can be seen as the connecting rod system (11) advantageously allows kinematic closure of the mechanism, while the bracing stringers (5) avoid their deformation even when only two of the claws or blades work (7), determining a better job and performance of all clamp-octopus components.
