ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Son conocidos diferentes tipos de aparatos para manipular piezas metálicas con una dimensión predominante y con elementos a soldar, basándose en la utilización de un puente grúa mediante el que, obviamente, en las operaciones de manipulación, se levita por encima del personal, requiriendo además una manipulación directa del operario sobre la pieza a montar, con la necesidad de utilizar elementos auxiliares/externos. Different types of devices for handling parts are known Metals with a predominant dimension and with elements to be welded, based on the use of a crane bridge through which, obviously, in handling operations, it is levitated above the personnel, also requiring a direct manipulation of the operator on the piece to be assembled , with the need to use auxiliary / external elements.
Por otro lado, los aparatos de manipulado convencionales no ofrecen la estabilidad que sería de desear, con los problemas e inconvenientes derivados de ello. On the other hand, conventional handling devices do not offer the stability that would be desired, with the problems and inconveniences arising from it.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El volteador de estructuras metálicas que se preconiza, ha sido concebido para resolver la problemática anteriormente expuesta, y conseguir además una serie de ventajas y prestaciones que se irán exponiendo a lo largo de la presente memoria descriptiva. The turner of metallic structures that is recommended, has been conceived to solve the problem previously exposed, and also achieve a series of advantages and benefits that will be exposed throughout the present specification.
Concretamente, el volteador de la invención ha sido concebido teniendo en cuenta una serie de premisas que se deben cumplir para que los trabajos a realizar resulten eficaces, y cuyas premisas corresponden a: Specifically, the turner of the invention has been designed taking into account a series of premises that must be met in order for the work to be carried out to be effective, and whose premises correspond to:
Cumplir la función para la que se diseñe, cual es la rotación en eje longitudinal de elementos con una dimensión predominante. Fulfill the function for which it is designed, which is the longitudinal axis rotation of elements with a predominant dimension.
Ser estable en el tiempo y estar protegido contra la corrosión ambiental, proyecciones por soldaduras e impactos derivados del normal uso del mismo. Contemplar las debidas conexiones y protecciones eléctricas para la seguridad frente a contactos indirectos de los operarios. Be stable over time and be protected against environmental corrosion, welding projections and impacts derived from normal use. Contemplate the proper connections and electrical protections for safety against indirect operator contacts.
Tener unas características de diseño que proporcionen seguridad y maniobrabilidad para los operarios de taller. Have design features that provide safety and maneuverability for workshop operators.
Teniendo en cuenta lo anteriormente expuesto, el volteador de la invención presenta como primera característica fundamental de novedad la incorporación de un brazo de carga o mástil principal provisto de un polipasto, lo que permite la carga y maniobras de colocación y situación de los elementos a soldar al elemento principal, considerado éste como la pieza metálica alargada, evitando la necesidad del uso de puente grúa durante las operaciones de montaje, resultando además autónomo en la realización de las operaciones de montaje, no necesitando la manipulación directa por parte del operario de la pieza a montar, desde que se quita del suelo hasta que queda finalmente instalada. Esta primera característica de novedad confiere seguridad a los operarios de la planta, ya que se pueden controlar elementos pesados a nivel de operario, sin levitar por encima del resto del personal, como ocurre con el uso de puente grúa. Otra característica de novedad del volteador es la incorporación de alimentación con protección eléctrica (enchufes y conectores), para los aparatos empleados en los trabajos. Taking into account the above, the turner of the invention has as its first fundamental characteristic of novelty the incorporation of a load arm or main mast provided with a hoist, which allows loading and maneuvering of placement and location of the elements to be welded to the main element, considered this as the elongated metal part, avoiding the need for the use of a bridge crane during assembly operations, being also autonomous in the realization of assembly operations, not requiring direct manipulation by the part operator to be mounted, from when it is removed from the ground until it is finally installed. This first characteristic of novelty confers safety to the operators of the plant, since heavy elements can be controlled at the operator level, without levitating above the rest of the personnel, as is the case with the use of a bridge crane. Another novelty feature of the turner is the incorporation of power with electrical protection (plugs and connectors), for the devices used in the work.
También incluye como característica de novedad la incorporación de unos soportes con arrolladores de cable para alojar las herramientas empleadas en condiciones de seguridad y comodidad para el operario. It also includes as a novelty feature the incorporation of supports with cable winders to house the tools used in conditions of safety and comfort for the operator.
Otra característica de novedad es la incorporación de un soporte para la colocación de la cara inferior de la pieza sobre la que se realiza la soldadura, quedando ésta perfectamente asentada en la posición escogida, mediante la elevación por cadena que discurre entre correspondientes ruedas y rodillos, incluido un tensor de la propia cadena. Another characteristic of novelty is the incorporation of a support for the placement of the lower face of the piece on which the welding is carried out, being this perfectly seated in the chosen position, by means of the chain lift that runs between corresponding wheels and rollers, including a chain tensioner itself.
Otra característica es la incorporación de medios de volteo de las piezas, constituidos a partir de una correa de giro que discurre entre cuatro ruedas, una de ellas motriz, relacionadas dos de ellas con respectivos brazos hidráulicos, permitiendo rotar de forma suave y suspendida la pieza metálica de que se trate, a merced del operario. Los brazos hidráulicos referidos, actúan sobre la correa levantando la pieza, quedando ésta envuelta y acunada por encima de la superficie del soporte, de manera tal que una vez suspendida la pieza, el accionamiento de la rueda motriz proporciona movimiento a la correa que, en su movimiento, hace rotar la propia pieza suspendida hasta dejarla con la superficie prevista de trabajo vista hacia arriba. Another feature is the incorporation of means of turning the pieces, constituted from a turning belt that runs between four wheels, one of them driving, related two of them with respective hydraulic arms, allowing to rotate the piece smoothly and suspended metal in question, at the mercy of the operator. The hydraulic arms referred to, act on the belt by lifting the piece, being wrapped and cradled above the surface of the support, so that once the piece is suspended, the drive of the driving wheel provides movement to the belt that, in its movement, rotates the suspended piece itself until it is left with the intended work surface facing up.
Otra característica de novedad es la incorporación en la parte inferior del bastidor general del volteador, de cuatro ruedas, dos de ellas motorizadas, constituyendo un sistema de traslación longitudinal del volteador a través de correspondientes raíles afianzados al suelo, confiriendo libertad de posicionamiento longitudinal a la pieza. Another characteristic of novelty is the incorporation in the lower part of the general frame of the turner, of four wheels, two of them motorized, constituting a system of longitudinal translation of the turner through corresponding rails anchored to the ground, giving freedom of longitudinal positioning to the piece.
Finalmente, incorpora otra característica de novedad, consistente en la incorporación de un soporte porta-herramientas y toma eléctrica, en el primer caso para un acceso mas rápido a los instrumentos que se empleen en los elementos tratados, y en el segundo caso para abastecer de energía a los equipos empleados en el trabajo. Finally, it incorporates another feature of novelty, consisting of the incorporation of a tool holder and electrical outlet, in the first case for faster access to the instruments used in the elements treated, and in the second case to supply energy to the equipment used at work.
