Description
Die zum Antrieb der Rotarygestänge bzw. Bohrwerkzeuge benötigten Mitnehmerstangen werden in der Regel aus Vollmaterial angefertigt. :Ulan hat auch bereits vorgeschlagen, für die Anfertigung von 'Mitnehmerstangen Winkelstahl zu verwenden. Die Durchführung dieses Vorschlages in der Praxis hat sich aber nicht bewährt. Die elektrisch handgeschweißten Nähte und der ungünstige Verlauf der Schweißnähte der Gewindeanschlüsse haben große Spannungserscheinungen ergeben. Infolgedessen ist das praktische Arbeiten mit diesen Mitnehmerstangen nicht von langer Dauer gewesen.The driving rods required to drive the rotary rods or drilling tools are usually made from solid material. : Ulan has already suggested to use angle steel for the production of 'drive rods. The implementation however, this proposal has not proven itself in practice. The electrically hand-welded Seams and the unfavorable course of the weld seams of the threaded connections have large Result in tension phenomena. As a result, working with these is practical Drive rods did not last long.
Nach der Erfindung sind zwei Winkelstähle mittels maschinenelektrischer Auftragschweißung zusammengefügt und schließen an sie sich die Gewindeanschlüsse mit schräg gestellten Schweißnähten an.According to the invention, two angle steels are machine-electric Overlay welded together and close to them the threaded connections with oblique welds.
Die Erfindung ergibt die Erfüllung aller Bedingungen, die an eine Mitnehmerstange im Bohrbetrieb gestellt werden. Ihr niedriges Gewicht erleichtert ihren Transport und bedeutet die Einsparung hochwertiger Stähle bzw. Arbeitskräfte. Die Schweißnähte sind in Rücksicht auf die geforderte Biegungs- und Torsionsfestigkeit schräg gestellt.The invention results in the fulfillment of all conditions that must be met by a Driving rod can be placed in drilling operation. Their low weight makes it easier their transport and means saving high-quality steels and labor. The weld seams are made in consideration of the required flexural and torsional strength inclined.
Nach einer Ausführungsform der Erfindung sind die Gewindeanschlüsse formgepreßte Schmiedestücke, deren Wandstärke sich der der Winkelstähle nähert. Hierdurch wird ein gleichmäßiger Spannungsverlauf in den Schweißnähten gesichert. In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Abb. i in Ansicht, in Abb. 2 im Querschnitt nach .der Linie II-11 der Abb. i und in Abb. 3 in Draufsicht dargestellt.According to one embodiment of the invention, the threaded connections Compression-molded forgings, the wall thickness of which approaches that of angle steels. This ensures an even tension curve in the weld seams. The drawing shows an embodiment of the subject matter of the invention in Fig. i in view, in Fig. 2 in cross section along line II-11 in Fig. i and in Fig. 3 shown in plan view.
Der TIauptteil der Mitnehmerstangebesteht aus den beiden Winkelstählen a und b, .die an den Stellen f mittels maschinenelektrischer Auftragschweißung zusammengefügt sind. Die Gewindeanschlüsse c, d sind formgepreßte Schmii:e@destücke, deren Wandstärke sich ,der Wandstärke der Winkelstähle nähert. Die Gewindeanschlüsse sind mit dem mittleren Teil der Mitnehmerstange an den schräg gestellten Schweißnähten e verbunden.The main part of the drive rod consists of the two angle steels a and b, which are joined together at points f by means of machine-electric build-up welding. The threaded connections c, d are compression-molded Schmii: e @ de pieces, the wall thickness of which approaches the wall thickness of the angle steels. The threaded connections are connected to the central part of the drive rod at the inclined weld seams e.
