OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una corona de perforación, es decir a una herramienta utilizada principalmente para la implantación de tuberías en cualquier tipo de terreno, con independencia de la dureza del mismo, incluso cuando éste es de piedra, roca, hormigón o similar, siendo utilizable también como apoyo para la construcción de túneles.The present invention relates to a drilling crown, that is to say a tool used mainly for the implantation of pipes in any type of terrain, regardless of the hardness of the same, even when it is made of stone, rock, concrete or similar, It can also be used as support for the construction of tunnels.
El objeto de la invención es conseguir una herramienta con mayor facilidad de penetración en el terreno, reduciendo así el tiempo de ejecución de la obra.The object of the invention is to achieve a tool with greater ease of penetration into the ground, thus reducing the execution time of the work.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El objeto de la invención se consigue debido a que la herramienta no ataca a todo el área del diámetro de la perforación, como es convencional, sino solamente al área de las propia corona, es decir a un área prácticamente circunferencial en lugar de circular, lo que determinan la mayor facilidad de penetración en el terreno a que se ha hecho mención con anterioridad.The object of the invention is achieved because the tool does not attack the entire area of the diameter of the perforation, as is conventional, but only the area of the crown itself, that is to say a practically circumferential rather than circular area, which determine the greatest ease of penetration into the land mentioned above.
Para ello y de forma más concreta la herramienta está compuesta por un cilindro hueco que constituye el soporte el soporte físico para una pluralidad de anillos, concretamente seis, montados coaxialmente y con funciones especificas y distintas. Concretamente el primer anillo constituye la cabeza de perforación y es donde lógicamente se encuentran los dientes de corte y los orificios de salida para el fluido que por un lado hace girar la herramienta y por otro facilita la evacuación del material, así como la refrigeración de la corona en su conjunto.For this and more specifically the tool is composed of a hollow cylinder that constitutes the support the physical support for a plurality of rings, specifically six, coaxially mounted and with specific and distinct functions. Specifically, the first ring constitutes the drill head and it is where the cutting teeth and the exit holes for the fluid that on one side rotates the tool and on the other facilitates the evacuation of the material, as well as the cooling of the material. crown as a whole.
Inmediatamente a continuación, un segundo anillo incorpora tres grupos de rodamientos para tres bandas de rodadura, una para la cabeza de perforación, otra para el anillo siguiente y la tercera para un cilindro interior.Immediately thereafter, a second ring incorporates three groups of bearings for three treads, one for the drill head, another for the next ring and the third for an inner cylinder.
En este cilindro interior están fijados la cabeza de perforación así como el tercero y el quinto anillo, mientras que el cuarto anillo está fijado por medio del cilindro exterior a los anillos segundo y sexto.In this inner cylinder the drill head is fixed as well as the third and fifth ring, while the fourth ring is fixed by means of the outer cylinder to the second and sixth rings.
Los anillos tercero, cuarto y quinto, forman una cámara estanca que es la que suministra el giro de la corona cuando entra el fluido a presión a través del cuarto anillo, que dispone de unas ranuras trasversales donde se ubican palas que se desplazan transversalmente, conforme barre la superficie sinuosa de los anillos tercero y quinto.The third, fourth and fifth rings form a sealed chamber that is what supplies the crown's rotation when the pressurized fluid enters through the fourth ring, which has transverse grooves where blades are located that move transversely, as Sweep the sinuous surface of the third and fifth rings.
Finalmente el sexto anillo es un conjunto de rodamientos para dos bandas de rodadura, una para el quinto anillo y otra para cilindro interior, estableciéndose en este último anillo la entrada de fluido y la cámara distribución del mismo.Finally, the sixth ring is a set of bearings for two treads, one for the fifth ring and one for the inner cylinder, establishing the fluid inlet and the distribution chamber in the latter ring.

A la vista de las figuras reseñadas, y en especial de la figura I5 puede observarse como la corona de perforación que se preconiza está constituida a partir de un primer anillo (1), que constituye la cabeza de perforación, donde se encuentran los dientes de corte (2), incorporando un rebaje postero-interior y escalonado en el que se acopla un cilindro interior (3) que se extiende a lo largo de toda la corona, afectando a los seis anillos constitutivos de la misma, como se verá seguidamente.In view of the figures outlined, and in particular of Figure I 5, it can be seen how the drilling crown that is recommended is constituted from a first ring (1), which constitutes the drill head, where the teeth are located cutting (2), incorporating a postero-interior and stepped recess in which an inner cylinder (3) is extended that extends along the entire crown, affecting the six constituent rings thereof, as will be seen below .
Inmediatamente detrás del primer anillo (1) se sitúa el segundo anillo (4) que cuenta con tres grupos de rodamientos, un primer grupo de rodamientos (5) actuantes sobre la banda de rodadura (6) de la cabeza de perforación (1), un segundo grupo de rodamientos (7), interior, actuante sobre el tubo interior (3), y un tercer grupo de rodamientos (8) actuantes sobre la banda de rodadura (9) del tercer anillo (10), tras el que se sitúa una cámara de presión (11) establecida entre dicho tercer anillo (10) y el cuarto anillo (12), en la que participa una junta de nylon (13).Immediately behind the first ring (1) is the second ring (4) which has three groups of bearings, a first group of bearings (5) acting on the tread (6) of the drill head (1), a second group of bearings (7), inner, acting on the inner tube (3), and a third group of bearings (8) acting on the tread (9) of the third ring (10), after which it is placed a pressure chamber (11) established between said third ring (10) and the fourth ring (12), in which a nylon seal (13) participates.
Al cilindro interior (3) están fijados tanto la cabeza de perforación (1) o primer anillo como el tercer anillo (10) y el quinto anillo (14), como se desprende de la observación de la figura 1, mientras que el cuarto anillo (12) está fijado a su vez al segundo anillo (4) y al último anillo (15) es decir al sexto anillo, mediante un cilindro exterior (16).Both the drill head (1) or first ring and the third ring (10) and the fifth ring (14) are attached to the inner cylinder (3), as can be seen from the observation in Figure 1, while the fourth ring (12) is in turn fixed to the second ring (4) and the last ring (15) ie the sixth ring, by an outer cylinder (16).
La cámara de presión (11) es la que suministra el movimiento giratorio a la corona cuando entra fluido a presión a través del cuarto anillo (12), que dispone a tal efecto de unas ranuras trasversales (17) donde se ubican palas que se desplazan transversalmente conforme barre la superficie sinuosa y enfrentada (18) de los anillos (10) y (14). Finalmente el sexto anillo (15) incorpora dos grupos de rodamientos, uno axial (19) de actuación sobre la banda de rodadura (20) del quinto anillo (14), y otro grupo de rodamientos radial e interior (21) de actuación sobre el cilindro interior (3).The pressure chamber (11) is the one that supplies the rotating movement to the crown when pressurized fluid enters through the fourth ring (12), which has for this purpose some transverse grooves (17) where moving blades are located transversely as it sweeps the sinuous and facing surface (18) of the rings (10) and (14). Finally, the sixth ring (15) incorporates two groups of bearings, one axial (19) acting on the tread band (20) of the fifth ring (14), and another radial and inner bearing group (21) acting on the inner cylinder (3).
Además este último anillo (15) incorpora la conexión (22) para la entrada de fluido y la cámara de distribución (23) del mismo. Furthermore, this last ring (15) incorporates the connection (22) for the fluid inlet and the distribution chamber (23) thereof.
