Description
Acoplamiento de amarre para grillete para eslabones de cadenas.Shackle mooring coupling for chain links.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un acoplamiento de amarre para grillete para eslabones de cadenas u otros elementos que componen las líneas de fondeo, que se constituye mediante un grillete, preferentemente en forma de "H", en cuyas ramas laterales, tanto en su tramo superior como en su tramo inferior, van montados sendos pasadores que constituyen el medio de retención de los eslabones que se unen al cuerpo del grillete, estando además dotado de una orejeta para una argolla sobre la que es susceptible de engancharse una carga.The present invention, as expressed in the set forth in this specification, refers to a link mooring for shackles for chain links or other elements which make up the funding lines, which is constituted by a shackle, preferably in the form of "H", in whose branches lateral, both in its upper section and in its lower section, are mounted two pins that constitute the means of retention of the links that attach to the shackle body, being also provided with an lug for a ring on which It is likely to catch a load.
El objeto de la invención es proporcionar un acoplamiento de amarre para grillete del tipo referido, en el que la orejeta constituye un elemento independiente, montable/desmontable a voluntad, permitiendo su sustitución o intercambio por el que más interese en cada momento.The object of the invention is to provide a shackle coupling for shackle of the type referred to, in which the lug constitutes an independent element, mountable / detachable at will, allowing replacement or exchange for the one that interests you most at all times.
Como es conocido, las cadenas de grandes dimensiones, especialmente las utilizadas en el mar, en plataformas petrolíferas, etc., están constituidas mediante una serie de eslabones engarzados entre sí, de manera que en este tipo de cadenas comentado la longitud de la cadena que se puede formar no puede ser elevada debido a que el tamaño de los eslabones da lugar a que la cadena adquiera un gran peso, de ahí que únicamente se puedan formar tramos de cadenas de longitud limitada. Para conseguir una cadena de elevada longitud será necesario unir diferentes tramos de cadenas y esa unión se realiza mediante grilletes a los que se vinculan los eslabones extremos de cada tramo de cadena.As is known, large chains dimensions, especially those used at sea, on platforms oil, etc., are constituted by a series of links linked together, so that in this type of chains commented on the length of the chain that can be formed not it can be high because the size of the links gives rise to for the chain to acquire a great weight, hence only they can form sections of chains of limited length. For to achieve a chain of high length it will be necessary to join different stretches of chains and that union is done by shackles to which the extreme links of each link are linked stretch of chain
Pues bien, los grilletes utilizados actualmente se constituyen a partir de una pieza que es mecanizada para conseguir un cuerpo con forma aproximadamente de "H", en donde los eslabones a unir se enganchan a dicho grillete y quedan retenidos por respectivos pasadores que se alojan en orificios realizados enfrentadamente en los tramos tanto superior como inferior, que se determinan en la configuración en "H" del comentado grillete.Well, the shackles currently used they are constituted from a piece that is mechanized to get a body shaped approximately "H", where the links to join are attached to the shackle and remain retained by respective pins that are housed in holes made in the upper and lower sections lower, which are determined in the "H" configuration of the commented shackle.
A veces es necesario que el grillete se complemente con una argolla sobre la que se aplica una fuerza por enganche de algún elemento, por ejemplo, para elevación, para la colocación de una boya, etc., de manera que tal argolla referida se vincula al grillete a través de una orejeta que forma parte de éste y que se obtiene también por mecanizado de la pieza de la que se parte para conseguir el mecanizado del cuerpo del grillete. Para conseguir esa orejeta se debe partir de una pieza cuyo tamaño ha de ser aproximadamente doble, al objeto de permitir no solamente realizar el mecanizado del grillete, sino también el mecanizado de la orejeta sobre la que posteriormente se fijará la argolla.Sometimes it is necessary that the shackle be complement with a ring on which a force is applied by hooking of some element, for example, for lifting, for placement of a buoy, etc., such that said ring is bind the shackle through a lug that is part of it and that is also obtained by machining the piece from which part to get the shackle body machining. For to get that lug should be from a piece whose size has to be approximately double, in order to allow not only perform the shackle machining, but also the machining of the lug on which the ring will be fixed later.
Evidentemente, ese mecanizado y el doble tamaño de la pieza de la que se parte, lleva consigo un encarecimiento del coste de obtención de la pieza, así como un notable tiempo de ejecución, independientemente de que a veces se requiere utilizar una orejeta que ha de soportar una determinada fuerza, en cuyo caso es necesario cambiar todo el grillete, con el coste que ello supone.Obviously, that machining and double size of the piece from which it starts, carries with it an increase in cost of the cost of obtaining the piece, as well as a remarkable time of execution, regardless of the fact that sometimes it is required to use an lug that has to withstand a certain force, in which case it is necessary to change the entire shackle, with the cost that it supposed.
El acoplamiento de amarre para grillete objeto de la invención, siendo del tipo de los constituidos por un grillete, preferentemente en forma de "H" o similar, presenta como característica fundamental de novedad la de incorporar una orejeta intercambiable, lo que posibilita utilizar en cada momento la más adecuada o que más interese.The mooring coupling for shackle object of the invention, being of the type constituted by a shackle, preferably in the form of "H" or similar, presents the fundamental characteristic of novelty is to incorporate a interchangeable lug, which makes it possible to use at any time the most appropriate or most interesting.
En tal sentido, la orejeta puede ir fijada internamente en el grillete en "H", o bien externamente a éste. En cualquier caso, dicha orejeta está formada por una pieza que puede considerarse en "U" con su rama intermedia o transversal determinada por una porción saliente afectada de un orificio para la fijación de la argolla correspondiente, mientras que las ramas laterales de tal pieza u orejeta están afectadas de orificios para paso de tornillos, bulones o similares que han de realizar la fijación de tal orejeta al grillete, con carácter desmontable y por tanto intercambiable de aquélla.In that sense, the lug can be fixed internally in the shackle in "H", or externally to East. In any case, said lug is formed by a piece which can be considered in "U" with its intermediate branch or transverse determined by an affected protruding portion of a hole for fixing the corresponding ring, while that the lateral branches of such a piece or lug are affected by holes for the passage of screws, bolts or the like to be make the fixing of such lug to the shackle, with character detachable and therefore interchangeable.
En el caso de que la fijación de la orejeta sea interior, entonces la separación de las ramas laterales de ésta será la correspondiente al grosor del tramo transversal interno del grillete en "H", quedando dichas ramas abrazando a dicho tramo transversal y fijadas a éste mediante los oportunos pasadores o bulones pasantes por los orificios de dichas ramas laterales de la orejeta y, por supuesto, a través de los oportunos orificios previstos al efecto en esa comentada rama o tramo transversal del grillete, quedando la parte saliente triangular de la orejeta sobresaliendo respecto del borde correspondiente a las ramas laterales del grillete en "H", y paralelamente entre dichas ramas laterales, es decir, en disposición longitudinal del conjunto orejeta/argolla respecto a la cadena.In the event that the fixation of the lug is interior, then the separation of the lateral branches of it will be the corresponding to the thickness of the internal transverse section of the shackle on "H", leaving these branches hugging said section transversal and fixed to it by means of the appropriate pins or bolts through the holes of said lateral branches of the lug and, of course, through the appropriate holes provided for that purpose in that commented branch or cross section of the shackle, leaving the triangular protruding part of the lug protruding from the edge corresponding to the branches shackle sides in "H", and in parallel between said lateral branches, that is, in longitudinal arrangement of the assembly lug / ring with respect to the chain.
Para el caso de fijación externa de la orejeta, se ha previsto que ésta presente sus ramas laterales con una notable mayor separación, ya que el grillete, es decir, ambas ramas laterales del mismo, deberá quedar abrazado entre las comentadas ramas laterales de la orejeta, efectuándose la fijación mediante pasadores o bulones pasantes a través de orificios previstos tanto en las ramas laterales del grillete en "H" como en las ramas laterales de la orejeta que abrazan aquéllas. En este caso, el conjunto orejeta/argolla queda en disposición transversal a la correspondiente cadena, disposición que permite soportar mayores fuerzas.In the case of external fixation of the lug, it is expected that this present its lateral branches with a noticeable greater separation, since the shackle, that is, both branches side of the same, should be embraced between the commented lateral branches of the lug, fixing by means of pins or bolts through holes provided for both in the lateral branches of the shackle in "H" as in the branches sides of the lug that embrace them. In this case, the lug / ring assembly is in transverse arrangement to the corresponding chain, provision that allows to support older forces.
Los orificios correspondientes a la rama transversal del grillete en "H", se realizarán mediante mecanizado durante el proceso de fabricación de dicho grillete en "H", aunque esos orificios pueden realizarse igualmente en una etapa posterior a la del proceso de fabricación de dicho grillete.The holes corresponding to the branch transverse shackle in "H", will be made by machining during the manufacturing process of said shackle in "H", although these holes can also be made in a stage after the manufacturing process of said fetter.
En base a las características referidas para el acoplamiento de amarre para grillete de la invención, se consiguen una serie de ventajas respecto a las convencionales, entre las que se pueden citar como más importantes las siguientes:Based on the characteristics referred to for the shackle mooring coupling of the invention, are achieved a series of advantages over conventional ones, among which The following may be cited as more important:
- Facilidad de fabricación, ya que no es necesario partir de una pieza metálica con dimensiones aproximadamente dobles para mecanizar el grillete y la orejeta, ya que estos dos elementos se realizan independientemente.- Ease of manufacturing, since it is not necessary to start with a metal part with dimensions approximately double to mechanize the shackle and the lug, already These two elements are performed independently.
- Posibilidad de realizar los orificios del cuerpo del grillete en la propia fase o proceso de mecanizado del mismo, o bien en una fase independiente al proceso de fabricación.- Possibility of making the holes of the shackle body in the own phase or machining process of the same, or in a phase independent of the process of manufacturing.
- La realización de los orificios en el cuerpo del grillete y por supuesto en la orejeta que se vincula al mismo, será en número variable, dependiendo del tipo de carga a enganchar y la colocación de la misma.- The realization of the holes in the body of the shackle and of course on the lug that is attached to it, it will be in variable number, depending on the type of load to be hooked and the placement of it.
- Mayor versatibilidad del grillete respecto a los convencionales, como consecuencia de lo expuesto en los puntos anteriores.- Greater versatility of the shackle compared to the conventional ones, as a result of what is stated in the points previous.
- Posibilidad de cambiar la orejeta cuando se requiera una mayor o menor fuerza, sin tener que cambiar todo el grillete.- Possibility to change the lug when it requires a greater or lesser force, without having to change all the fetter.
