La invención concierne a un tubo telescópico para una instalación de descarga en un carro de carga para hornos de coque, que comprende un tubo de llenado, un tubo exterior verticalmente desplazable que abraza al tubo de llenado, una disposición de junta para sellar la rendija anular entre el tubo de llenado y el tubo exterior y que presenta una junta deformable elásticamente que abraza al tubo de llenado, y un dispositivo de apriete que actúa sobre la junta y que presenta un accionamiento para realizar la función de apriete y suelta durante el funcionamiento, pudiendo ser presionada la junta por apriete del dispositivo de apriete contra el tubo de llenado y contra una superficie de brida unida con el tubo exterior, y quedando la junta nuevamente libre de la pared del tubo de llenado por suelta del dispositivo de apriete, con lo que el tubo exterior puede ser desplazado verticalmente sin desgaste de la junta.The invention concerns a telescopic tube for an unloading installation in a cargo car for furnaces coke, comprising a filling tube, an outer tube vertically movable that hugs the filling tube, a gasket arrangement to seal the annular slit between the tube filling and the outer tube and presenting a deformable joint elastically hugging the filling tube, and a device for tighten acting on the joint and presenting a drive to perform the squeeze and release function during operation, the joint can be pressed by tightening the clamping device against the filling tube and against a flange surface attached to the outer tube, and the seal remaining Newly free from the wall of the loose fill tube clamping device, so that the outer tube can be displaced vertically without wear of the joint.

Los carros de carga para una explotación moderna de hornos de coque están equipados con un tubo telescópico que transfiere el carbón de alimentación desde una instalación de descarga que se encuentra por debajo de la tolva de llenado hasta la cámara del horno de coque. El tubo telescópico está construido en varias partes y presenta al menos un tubo de llenado conectado a la instalación de descarga y un tubo exterior que puede ser subido y bajado. En la construcción del tubo telescópico se concede un valor especial a una ejecución hermética, de modo que durante la carga del carbón en la cámara del horno de coque no lleguen emisiones de llenado al medio ambiente a través del tubo telescópico. En un tubo telescópico conocido por el documento DE-C 29 22 571 el tubo de llenado conectado fijamente a la instalación de descarga presenta en su extremo inferior un collar anular lleno de arena. El tubo exterior verticalmente desplazable posee en su extremo superior una regleta de sellado que penetra en el lecho de arena al hacer descender el tubo exterior. La ejecución conocida no permite compensar diferencias de altura entre el canto inferior del tubo exterior descendido y el marco del agujero de llenado.Cargo trucks for a modern operation of coke ovens are equipped with a telescopic tube that transfers the feed coal from an installation of discharge located below the filling hopper until the coke oven chamber. The telescopic tube is built in several parts and has at least one filling tube connected to the discharge facility and an outer tube that can be climbed and gone down. In the construction of the telescopic tube a value is granted special to a hermetic execution, so that during the loading of the coal in the coke oven chamber does not reach emissions of environmentally filled through the telescopic tube. In a tube telescopic known from document DE-C 29 22 571 the filling tube fixedly connected to the discharge installation It presents at its lower end an annular necklace filled with sand. He vertically movable outer tube has at its upper end a sealing strip that penetrates the sand bed when lower the outer tube. The known execution does not allow compensate for height differences between the lower edge of the tube exterior descended and the hole frame filled.

Debido a variaciones locales de la mampostería del techo del horno se pueden presentar considerables diferencias de altura a lo largo de dicho techo, las cuales tienen que ser compensadas por el tubo telescópico al llenar las distintas cámaras del horno de coque. A este fin, se incorporan en los tubos telescópicos unos compensadores que, por un lado, impiden la salida de emisiones de llenado y, por otra lado, compensan en cierta medida, debido a su capacidad de dilatación, diferencias de altura de un marco de agujero de llenado a otro. En una ejecución conocida por el documento EP-B 0 632 117 el tubo de llenado unido fijamente con la instalación de descarga y el tubo exterior susceptible de ser subido y bajado están rodeados por un manguito construido como un tubo ondulado que se dilata al hacer descender el tubo exterior. El manguito, fabricado casi siempre de acero o de un tejido especial, posee sólo una capacidad de dilatación limitada que está en relación directa con su longitud de construcción y que no puede ser sensiblemente influenciada ni por la ejecución constructiva ni por la elección del material. En la práctica, especialmente en instalaciones antiguas de hornos de coque, la distancia entre el canto inferior del tubo telescópico en estado elevado y el canto superior del marco del agujero de llenado es con frecuencia mayor que la dilatación admisible del compensador, de modo que zonas enteras del techo del horno tienen que ser elevadas con el marco del agujero de llenado en acciones complicadas, ligadas a considerables costes, y llevadas a la zona de las dilataciones admisibles del compensador.Due to local variations of the masonry considerable differences of height along said roof, which have to be compensated by the telescopic tube when filling the different chambers from the coke oven. To this end, they are incorporated into the tubes telescopic compensators that, on the one hand, prevent the exit of filling emissions and, on the other hand, compensate in some measure, due to its expansion capacity, height differences from one filling hole frame to another. In a known execution by EP-B 0 632 117 the filling tube fixedly connected to the discharge system and the outer tube liable to be raised and lowered are surrounded by a sleeve built as a wavy tube that expands by lowering the outer tube The sleeve, almost always made of steel or a special fabric, has only a limited expansion capacity that is directly related to its construction length and that can be significantly influenced by execution constructive or by the choice of material. In practice, especially in old coke oven installations, the distance between the lower edge of the telescopic tube in state raised and the top edge of the fill hole frame is with frequency greater than the allowable expansion of the compensator, of so that entire areas of the oven roof have to be elevated with the frame of the filling hole in complicated actions, linked at considerable costs, and taken to the dilatation zone allowable compensator.

Un tubo telescópico con las características descritas al principio es conocido por el documento EP-
A 0 396 877. En la ejecución conocida está prevista una junta elásticamente deformable que abraza al tubo de llenado, que está dispuesta en una carcasa anular limitada por dos anillos de brida y unida con el tubo exterior y que es solicitada radialmente por una banda de apriete colocada dentro de la carcasa. El accionamiento del dispositivo de apriete presenta un sistema de tracción que contrae los extremos de la banda de apriete.

En el proceso de apriete se comprime la junta por medio de un movimiento de ajuste vertical del anillo de apriete y se presiona ésta contra el tubo de llenado y contra las correspondientes superficies de contacto del tubo exterior. Después de soltar el dispositivo de apriete se deforma la junta volviendo a su estado anterior, con lo que el tubo exterior puede ser desplazado verticalmente sin que la junta esté expuesta a un desgaste. Ejecuciones preferidas de la disposición según la invención se describen en las reivindicaciones 2 y 3.The problem is solved according to the invention in a telescopic tube of the structure described the principle because the gasket is arranged in an annular space limited by a ring flange and a pipe segment and is requested in axial direction by a vertically movable clamping ring connected to the drive In the tightening process the joint is compressed by middle of a vertical adjustment movement of the clamping ring and it press it against the filling tube and against the corresponding contact surfaces of the outer tube. After releasing the clamping device deforms the joint by returning to its previous state, so that the outer tube can be displaced vertically without the seal being exposed to wear. Preferred embodiments of the arrangement according to the invention are described in claims 2 and 3.
