Description

Schntzkape fär Bhrrohre. Die Rohre von Bohrgestängen besitzen an ihren Enden ein konisches Gewinde, das während des Transportes leicht beschädigt wird. Um diesem Ubelstand abzuhelfen, verschraubt man die Enden der Rohre mit Schutzkappen aus einem leichten elastischen Werkstoff, wie Gummi oder gummiähnlichenKunststoff. Die in daß Muffenende eines Bohrrohres eingeschraubte Schutzkappe ist als ein Hohl- körperausgebildet, der ztm Rehrinnern hin offen ist « Der Gewindeteil der Kappe hat die Ausgestaltung eines Rohrstückes. Hierdurch entstehen Nachteile in verschie- dener Hinsicht. Bei auftretenden Btõßen, Schlägen gegen die Kappe findet leicht eine Deformierung des Gewinde- teils der elastischen Kappe statt, ao daß die Sehüts- kappe leicht herausfällt. Des weiteren ist die Schytz- kappe, bedingt durch ihren verhältnismäßig großen Dureh- messar, nieht griffig. Die au4ezeigten Nachteile auf einfachste Weise s bheben st die Erfindm zum Zweck. Ihr Wesen wirdinebe-sondere darin geseheng daß die in das Muffenen- de eines Bohrrohres eingeschraubte Schutzkappe als ein nachaußen offener Hohlkörper ausgebildet ist. Der Efindungsgegenstand ist auf der Eich- nung in einoy beispielswlsen AüsfHhrungsfrm sohesatish im Längsschnitt dargestellt. raa äus der Zeichnung ersìeh'tlieh, besteht dieerfindungegezäß ausgeataltete Kappe aus einem Geviln- detell 1 und einem Planzoh 2.

The tubes of drill rods have a conical thread at their ends, which is easily damaged during transport. To remedy this Ubelstand, one screwed the ends of the tubes with protective caps made of a light elastic material such as rubber or rubber-like plastic. The one in that socket end The protective cap screwed into the drill pipe is designed as a hollow physically trained, which is open to the inside of the deer " The threaded portion of the cap is in the form of a Pipe section. This creates disadvantages in different in this respect. If bumps occur, blows against the cap easily finds a deformation of the thread part of the elastic cap instead, ao that the protective cap easily falls out. Furthermore, the Schytz- cap, due to its relatively large diameter messy, not easy to grip. The disadvantages shown in the simplest way In this way, inventions are used for the purpose. Your essence is particularly seen in the fact that the de a drill pipe screwed in protective cap as a outwardly open hollow body is formed. The object of the invention is on the calibration In some examples, for example, the statement of sohesatish shown in longitudinal section. there is no evidence of the drawing dieinventionegezäß expired cap made of a Geviln- detell 1 and a Planzoh 2.
