Description
Dispositivo para el transporte de metal fundido.Metal transport device molten.
La presente invención se refiere a un dispositivo para el transporte de metal fundido, de los que comprenden una cuchara destinada a contener y transportar la colada o metal fundido para su vertido por la boca superior y que están dispuesta sobre un bastidor para su basculación durante la operación de vaciado o descarga.The present invention relates to a device for transporting molten metal, of which comprise a spoon intended to contain and transport the laundry or molten metal for pouring through the upper mouth and that are arranged on a frame for tilting during the emptying or unloading operation.
En la actualidad para el transporte de metal fundido se utilizan diversos tipos de cucharas o recipientes especialmente adaptados para este servicio. Estas cucharas pueden estar colgadas de grúas que las transportan, o en el caso de necesitar una mayor movilidad y un tamaño reducido, las cucharas están dispuestas sobre unos bastidores o estructuras que pueden ser transportados mediante carretillas elevadoras convencionales. Para ello, estos bastidores o estructuras de soporte presentan inferiormente unos alojamientos o pasajes para el agarre del dispositivo mediante las uñas de la carretilla elevadora.Currently for metal transport various types of spoons or containers are used specially adapted for this service. These spoons can be hung on cranes that transport them, or in the case of need more mobility and a reduced size, the spoons are arranged on racks or structures that can be transported by conventional forklifts. For this, these racks or support structures have inferiorly some housings or passages for the grip of the device using forklift fingernails.
Estos dispositivos presentan diversos problemas entre los que cabe destacar el riesgo de vertido involuntario de una parte de la colada al realizar maniobras bruscas durante el transporte y la falta de control en el vertido del metal cuando se vuelca la cuchara para su descarga, saliendo el metal por la boca superior de forma irregular dependiendo del ángulo basculación de la cuchara.These devices present various problems among which the risk of involuntary discharge of a part of the laundry when performing sudden maneuvers during transport and lack of control in the pouring of metal when dump the spoon for unloading, leaving the metal through the mouth upper irregularly depending on the tilting angle of the spoon.
Otros inconvenientes de estos dispositivos es que la cuchara antes de ser utilizada debe ser sometida a un precalentamiento para evitar el enfriamiento del metal fundido a transportar y que dicha cuchara debe disponer de un aislamiento adecuado para reducir la transferencia y pérdida de calor.Other drawbacks of these devices is that the spoon before being used must be subjected to a preheating to prevent cooling of molten metal to transport and that said spoon must have an insulation Suitable to reduce heat transfer and loss.
El dispositivo para el transporte de metal fundido de esta invención presenta unas particularidades constructivas que permiten un transporte seguro del metal fundido, sin riesgo de derrames accidentales y un mayor control del vertido de dicho metal cuando se vacía la cuchara.The device for transporting metal Cast of this invention has some peculiarities construction that allow safe transport of molten metal, no risk of accidental spillage and greater control of spillage of said metal when the spoon is emptied.
El dispositivo comprende una cuchara que presenta lateralmente y próxima a su boca superior una boca de descarga fijada a la boca lateral de un tubo de descarga, el cual presenta una cierta inclinación lateral y se encuentra montado con posibilidad de giro respecto a la estructura de soporte o bastidor, definiendo dicho tubo de descarga el eje de basculación de la cuchara respecto a la estructura de soporte.The device comprises a spoon that it presents laterally and next to its upper mouth a mouth of discharge attached to the side mouth of a discharge tube, which It has a certain lateral inclination and is mounted with possibility of rotation with respect to the support structure or frame, said discharge tube defining the tilt axis of the spoon with respect to the support structure.
De esta forma al bascular la cuchara, el vertido o salida del metal fundido se realiza por la boca lateral de dicho tubo, de forma más controlada, ya que la boca está dispuesta en una posición fija respecto a la estructura de soporte y el caño del tubo hace la función de aforo, limitando y regulando la salida del metal fundido.In this way when the spoon is tilted, the spill or exit of the molten metal is done through the lateral mouth of said tube, in a more controlled way, since the mouth is arranged in a fixed position with respect to the support structure and the pipe spout It acts as a capacity, limiting and regulating the metal output molten.
La cuchara comprende una tapa abatible para el cierre de su boca superior y evitar derrames involuntarios del metal fundido debido a posibles maniobras bruscas durante el transporte del dispositivo con carretilla elevadora o cualquier otro medio de transporte.The spoon comprises a folding lid for the Close your upper mouth and avoid involuntary spills of the molten metal due to possible abrupt maneuvers during transport of the device with forklift or any other conveyance.
También se ha previsto que la cuchara sea de un material cerámico aislante y de gran resistencia. Esto permite que no sea necesario realizar un precalentamiento de la cuchara antes de verter el metal fundido en su interior y evitar la pérdida de calor al exterior que comporta una solidificación del metal en su interior, si está por un tiempo prolongado, o al menos su densificación.It is also planned that the spoon is of a Ceramic insulating material and high strength. This allows it is not necessary to preheat the spoon before of pouring molten metal inside and preventing the loss of heat to the outside that entails a solidification of the metal in its inside, if it is for a long time, or at least its densification
El tubo de descarga presenta el extremo superior
cerrado y dispone en el extremo inferior, de una boca para la salida
de la colada, provista de una tapa de cierre para impedir el
vertido accidental de la colada durante el transporte. Esta tapa
colabora con la tapa abatible de la cuchara en evitar la salida
accidental de metal fundido al exterior. Esta tapa del tubo de
descarga está relacionada con un cilindro hidráulico de
accionamiento para su control a dis-
tancia.The discharge tube has the upper end closed and has at the lower end, a mouth for the exit of the laundry, provided with a closing lid to prevent accidental pouring of the laundry during transport. This lid collaborates with the folding lid of the spoon in preventing accidental outflow of molten metal to the outside. This discharge tube cover is related to a hydraulic actuating cylinder for its control in
tancia
El tubo de descarga se encuentra fijado sobre la estructura de soporte por unas abrazaderas desmontables, que permiten mediante su extracción la liberación, respecto a la estructura de soporte, del conjunto formado por la cuchara y el tubo de descarga.The discharge tube is fixed on the support structure by detachable clamps, which they allow the release, with respect to the support structure, of the set formed by the spoon and the tube Download
El dispositivo comprende al menos dos cilindros hidráulicos para el accionamiento basculante de la cuchara respecto a la estructura de soporte. De esta forma el fallo de uno de dichos cilindros no comporta la caída inmediata de la cuchara en el caso de estar procediendo al vertido del metal fundido por el tubo de descarga.The device comprises at least two cylinders hydraulic for the tilt bucket drive to the support structure. In this way the failure of one of these cylinders does not involve the immediate fall of the bucket in the case if the molten metal is being poured through the pipe discharge.
El dispositivo comprende conexiones hidráulicas de todos los elementos hidráulicos con la carretilla de transporte para su accionamiento desde los mandos de ésta.The device comprises hydraulic connections of all hydraulic elements with the transport truck for its operation from its controls.
