Description

Die Erfindung bezieht sich auf einen Spülkopf für biegsame Rohrwellen zum Zuleiten des Kühlwassers durch die Rohrwelle und zum Spülen des Bohrkopfes. Bei den biegsamen Rohrwellen, wie solche seit einiger Zeit im Gebrauch sind, wird das für den Bohrkopf erforderliche Spülwasser durch die hohle Welle geleitet und letztere gleichzeitig gekühlt. Die Verbindung des Antriebsmotors mit der Rohrwelle erfolgt durch Zwischenschaltung vorliegenden Spülkopfes.The invention relates to a flushing head for flexible pipe shafts for feeding the cooling water through the tubular shaft and for flushing the drill head. With the flexible ones Tubular shafts, such as have been in use for some time, the flushing water required for the drill head through the hollow shaft and the latter cooled at the same time. The connection of the drive motor with the tubular shaft takes place through the interposition of the existing flushing head.

In der Muffe r, welche an beiden Enden mit Muttern 2 sowie Stopfbüchsen 3 mit Packungen 4 versehen ist, liegt ein drehbares Wellenstück 5, welches mit einer zentralen Bohrung 6 versehen ist. Diese Bohrung ist nur ein gewisses Stück durchgeführt und ist das Wellenstück an dem geschlossenen Ende mit Außengewinde 7 versehen zum Anschluß an den Antriebsmotor. Das andere offene Ende des Wellenstückes besitzt Innengewinde 8, in welches die biegsame Rohrwelle eingeschraubt wird. Die Muffe besitzt in der Mitte einen das Wellenstück umgebenden Hohlraum 10, zu welchem ein Rohr 9 führt, das mit einer Wasserleitung in Verbindung steht. Das Wellenstück ist mit mehreren zu der zentralen Bohrung führenden üffnungen 11 versehen, durch welche das in den Hohlraum 10 unter Druck gelangende Wasser in das Wellenstück und von hier in die Rohrwelle und zu dem Bohrkopf gelangt. Da mehrere öffnungen 11 zu der zentralen Bohrung 6 führen, ist ein Eintreten des Wassers trotz der schnellen Umdrehung der Welle gewährleistet, wobei ein Austreten des Wassers zwischen Muffe und Wellenstück durch die Stopfbüchsen verhindert wird. Ein Verschieben des Wellenstückes 5 in der Muffe wird durch einen Stellring 12 verhindert.In the socket r, which at both ends with nuts 2 and stuffing boxes 3 with Packs 4 is provided, is a rotatable shaft piece 5, which with a central Hole 6 is provided. This drilling is carried out and is only a certain distance the shaft piece provided at the closed end with an external thread 7 for connection to the drive motor. The other open end of the shaft piece has internal threads 8, into which the flexible tubular shaft is screwed. The sleeve has a shaft piece in the middle that surrounds it Cavity 10, to which a pipe 9 leads, which is connected to a water pipe stands. The shaft piece has several openings leading to the central bore 11 provided, through which the water entering the cavity 10 under pressure gets into the shaft piece and from here into the tubular shaft and to the drill head. There several openings 11 to the central bore 6 lead, water is guaranteed to enter despite the rapid rotation of the shaft, the leakage of the water between the sleeve and the shaft piece through the stuffing boxes is prevented. A shift of the shaft piece 5 in the sleeve is prevented by an adjusting ring 12.
