Description
Stoßtränkgerät für den Abbau von Kohle.Impact impregnator for mining coal.
Die Erfindung bezieht sich auf ein Stoßtränkgerät für den Abbau von Kohle, das aus einem im Bohrloch durch Aufblähen abdichtenden, dehnbaren Schlauch besteht. Am Ausflußende dieses Blähschlauches befindet sich eine Düse, um innerhalb des Blähschlauches einen solchen Druck des Tränkwassers aufbauen zu lassen, damit die Außenwandung des Schlauches das Bohrloch in gehöriger Weise abdichtet. Bei den bekannten Ausführungsformen ist die Düse dehnbar ausgestaltet und von dem gleichen Werkstoff gebildet, wie das aufblähbare Schlauchstück. Durch die Ausdehnung innerhalb der Düsenwandung vermag sich nur ein ungenügender Druck in der Schlauchblase aufzubauen, so daß eine ungenügende Abdichtung entsteht.The invention relates to a shock impregnating device for the mining of coal, which is extracted from a borehole by inflation sealing, stretchable hose. At the outflow end of this inflation tube there is a nozzle to inside of the inflation hose to build up such a pressure of the drinking water that the outer wall of the hose does Seals the borehole in a proper manner. In the known embodiments, the nozzle is designed and expandable made of the same material as the inflatable tube. Due to the expansion within the nozzle wall only insufficient pressure can build up in the tube bladder, so that an insufficient seal arises.
Die Erfindung hat sich zur Aufgabe gestellt, die aufgezeigten Nachteile auf einfachste WeiseThe invention has set itself the task of solving the disadvantages indicated in the simplest possible way

zu beheben. Ihr Wesen wird insbesondere darin gesehen, daß das düsenartige Ausflußende undehnbar ausgestaltet ist·to fix. Its essence is seen in particular in that the nozzle-like outlet end is inextensible
Der Erfindungsgegenstand ist auf der Zeichnung in einer beispielsweisen Ausführungsform schematisch im Längsschnitt dargestellt.The subject matter of the invention is shown schematically in an exemplary embodiment in the drawing shown in longitudinal section.
Die Erfindung geht von der Erkenntnis aus,The invention is based on the knowledge
daß dann ein abdichtendes Aufblähen des Schlauches und ein genügender Durchgang des Tränkwassers gewährleistet ist, wenn das Ausflußende von einer undehnbaren Düse gebildet wird. Der aufblähbare Teil eines TränkSchlauches trägt auf der Zeichnung die Kennziffer 1 und verjüngt sich an seinem Ausflußende zu einer Düse 2.that a sealing inflation of the hose and a sufficient passage of the drinking water is guaranteed, when the outlet end is formed by an inextensible nozzle will. The inflatable part of a drinking hose is bulky The number 1 in the drawing and tapers at its outlet end to form a nozzle 2.
Um das dösenartige Ausflußende 2 undjshnharAround the doze-like discharge end 2 undjshnhar
auszugestalten, befindet sich in der Düsenwandung eine starre Einlage 3· Diese starre Einlage kann wie auf der Zeichnung dargestellt, aus einem metallischen Rohrstück bestehen. Der Erfindungsgegenstand wird dadurch nicht verlassen, daß die starre Einlage 3 in der Wandung des düsenartigen Ausflußendes aus Fäden mit hoher Festigkeit besteht, die in Umfangsrichtung auf die dehnbare Gewebeeinlage 4 gewickelt sind.design, there is a rigid insert 3 in the nozzle wall · This rigid insert can be as shown in the drawing shown, consist of a metallic pipe section. The subject of the invention is not left by the fact that the rigid insert 3 in the wall of the nozzle-like outflow end consists of high-strength threads that are wound onto the stretchable fabric insert 4 in the circumferential direction are.
