La máquina está provista de unos soportes para albergar dispositivos de limpieza de tuberías que, en general, se tratará de herramientas eléctricas, tales como amoladoras, cepilladoras o similares. The present invention relates to an exterior pipe and pipe cleaning machine comprising a structure designed to be able to adapt and embrace ducts of different diameters. The machine is provided with supports to house pipe cleaning devices that, in general, will be power tools, such as grinders, planers or similar.
La máquina de la invención encuentra especial aplicación en la industria relacionada con el mantenimiento de las redes de oleoductos y gasoductos, así como de cualquier tipo de conductos o tuberías en general. The machine of the invention finds special application in the industry related to the maintenance of oil and gas pipeline networks, as well as any type of conduits or pipes in general.
PROBLEMA TÉCNICO A RESOLVER Y ANTECEDENTES DE LA INVENCIÓN TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION
El procedimiento para la limpieza exterior de conductos y tuberías empleado habitualmente, ya sea para eliminar el recubrimiento exterior de óxido creado o para eliminar impurezas presentes, es un proceso realizado por un operario de manera manual con un cepillado de la superficie del conducto mediante máquinas radiales o cepilladoras que incorporan cerdas de alambre. Este procedimiento manual presenta una serie de desventajas como que pueda el resultado ser de una calidad muy variable, no es seguro para el operario que realiza la limpieza y, sobre todo, no es eficaz por resultar muy lento. The procedure for the external cleaning of conduits and pipes usually used, either to eliminate the outer coating of rust created or to eliminate impurities present, is a process performed by an operator manually with a brushing of the surface of the conduit by radial machines or planers incorporating wire bristles. This manual procedure presents a series of disadvantages such that the result may be of a very variable quality, it is not safe for the operator who performs the cleaning and, above all, it is not effective because it is very slow.
Como alternativa al procedimiento manual, son conocidos en el estado de la técnica otras herramientas o máquinas para la limpieza de tuberías. Como por ejemplo en el documento de patente GB2500106 se describe una herramienta para la eliminación de recubrimientos en tuberías que se acopla a la tubería y elimina el recubrimiento mediante materiales abrasivos dispuestos en su cara interna. Sin embargo, el dispositivo descrito en este documento presenta, como principal desventaja, una baja eficacia y la imposibilidad para ser adaptado a conductos de diferentes diámetros. As an alternative to the manual procedure, other tools or machines for pipe cleaning are known in the state of the art. As for example in patent document GB2500106 a tool for the elimination of coatings in pipes is described which is coupled to the pipe and removes the coating by abrasive materials arranged on its inner face. However, the device described in this document presents, as the main disadvantage, low efficiency and the inability to be adapted to ducts of different diameters.
La presente invención evita estas desventajas proporcionando una máquina limpiadora de conductos que se adapta a un amplio rango de diámetros de conductos con una alta versatilidad y eficacia. The present invention avoids these disadvantages by providing a duct cleaning machine that adapts to a wide range of duct diameters with high versatility and efficiency.
DESCRIPCIÓN DE LA INVENCIÓN La presente invención tiene por objeto una máquina de limpieza exterior de conductos. La máquina de la invención comprende una estructura formada por dos discos y una pluralidad de barras que los unen. Los discos tienen un sistema de apertura y cierre mediante el cual permiten que la estructura pueda ser ubicada y fijada alrededor de un conducto para proceder a su limpieza. DESCRIPTION OF THE INVENTION The object of the present invention is an external duct cleaning machine. The machine of the invention comprises a structure formed by two discs and a plurality of bars that join them. The discs have an opening and closing system by means of which they allow the structure to be located and fixed around a conduit for cleaning.
La máquina de la invención incorpora también un sistema para el desplazamiento por el conducto, unido a la estructura, y al menos un dispositivo de limpieza de conductos ubicado en un soporte que está unido a la estructura. A pesar de que en la presente invención se habla de conductos, esto debe entenderse de forma genérica y no restrictiva, incluyendo todo tipo de conductos, tubos o tuberías. De esta forma, la máquina de la invención puede utilizarse para todo tipo de conductos, pudiendo eliminar tanto el recubrimiento exterior de los conductos como restos de óxido o impurezas presentes. The machine of the invention also incorporates a system for displacement through the duct, attached to the structure, and at least one duct cleaning device located on a support that is attached to the structure. Although the present invention refers to conduits, this should be understood in a generic and non-restrictive manner, including all types of conduits, tubes or pipes. In this way, the machine of the invention can be used for all types of ducts, being able to eliminate both the outer covering of the ducts and the remains of rust or impurities present.
La máquina de la invención puede incorporar un contrapeso para facilitar el movimiento rotacional por el conducto cuando se usa de forma manual mediante un operario. La máquina de la invención puede incorporar un motor para activar el sistema de desplazamiento, de forma que la utilización de la máquina pueda realizarse de forma autónoma. En estos casos, la máquina puede llevar incorporado un microprocesador en el que esté programado un movimiento o recorrido determinado, simplemente, un receptor mediante el cual pueda controlarse la máquina a través de un mando a distancia o cualquier otro sistema de control remoto. De acuerdo con la invención, el dispositivo de limpieza que incorpora la máquina es una herramienta eléctrica como, por ejemplo, una amoladora, una cepilladora, una lijadora o una herramienta similar que, como medio abrasivo puede incorporar un cepillo de alambres, una lija o combinaciones de estas o de otros medios conocidos para alcanzar este resultado. The machine of the invention can incorporate a counterweight to facilitate rotational movement through the duct when used manually by an operator. The machine of the invention can incorporate a motor to activate the displacement system, so that the use of the machine can be carried out autonomously. In these cases, the machine can have a microprocessor incorporated in which a certain movement or route is programmed, simply a receiver through which the machine can be controlled through a remote control or any other remote control system. In accordance with the invention, the cleaning device that incorporates the machine is an electric tool such as a grinder, a planer, a sander or a similar tool that, as an abrasive medium, can incorporate a wire brush, a sandpaper or combinations of these or other known means to achieve this result.
El soporte para albergar el dispositivo de limpieza también puede comprender un elemento de regulación de la distancia al conducto que puede ser, por ejemplo, un tornillo. Así, el elemento de regulación permite regular a la medida requerida la proximidad del dispositivo de limpieza al conducto, pudiendo regular con ello el grado de cepillado y conseguir con ello mayor homogeneidad en el acabado. The support for housing the cleaning device can also comprise an element for regulating the distance to the conduit, which can be, for example, a screw. Thus, the regulating element allows the proximity of the cleaning device to the duct to be adjusted to the required extent, thereby being able to regulate the degree of brushing and thereby achieve greater homogeneity in the finish.
Acerca del sistema de desplazamiento, hay que decir que puede estar ubicado en cualquier parte de la estructura, aunque normalmente está localizado en cada uno de los discos. El sistema de desplazamiento, normalmente, se trata de un juego de rodamientos que pueden ser de bolas o cilindricos, pudiendo estos últimos incorporar sistemas para el desplazamiento en cualquier dirección. En función del diámetro del conducto, la estructura de la máquina puede tener de entre 2 y 12 barras. About the displacement system, it must be said that it can be located anywhere in the structure, although it is normally located on each of the disks. The displacement system is normally a set of bearings that can be ball or cylindrical, the latter being able to incorporate systems for displacement in any direction. Depending on the diameter of the duct, the structure of the machine can have between 2 and 12 bars.
El sistema de apertura y cierre del disco para abrazar y adaptarse al conducto puede ser una bisagra que se puede complementar con algún mecanismo de seguridad para evitar aperturas descontroladas. The system for opening and closing the disc to hug and adapt to the duct can be a hinge that can be complemented with some safety mechanism to avoid uncontrolled openings.
