Abstract
In stark gekrümmte oder horizontal verlaufende Tief bohrungen kann ein Kalibermeßgerät (18) nur mit Hilfe eines Gestänges eingefahren werden. Um dies zu ermög lichen, ist am Ende des Gestänges eine Hülse (1) mit einer Übergangsmuffe (3) angebracht, die am Ende einen Führungsschuh (2) trägt und die das Kalibermeßgerät (18) aufnimmt. Das Kalibermeßgerät (18) weist an seinem vor deren Ende einen Adapterschuh (16) auf, der in eine Lager büchse (9) in der Hülse (1) einsetzbar ist und das Ka libermeßgerät (18), dessen Außendurchmesser kleiner ist als der Durchmesser der Hülsenbohrung, in der Hülsen bohrung zentriert. Das Kalibermeßgeräft (18) bleibt da her frei von Verformungen, denen die Hülse (1) beim Durchfahren der Tiefenbohrung unterliegt. Die Hülse (1) ist mit Öffnungen (7) versehen, durch die die Arme (26) des Kalibermeßgeräts (18) ausgefahren werden können. Um die Arme (26) zu den Öffnungen (7) auszurichten, sind Orientierungsmittel (11, 15, 20, 22) vorgesehen, die den Adapterschuh (16) beim Einführen in die Lager büchse (9) in seiner Winkelstellung zur Hülse (1) aus richten (Figur 1). In deeply curved or horizontal depths A caliber measuring device (18) can only bore holes with the help of a linkage. To make this possible Lichen, is at the end of the rod with a sleeve (1) a transition sleeve (3) attached to the end Carries guide shoe (2) and which the caliber measuring device (18) records. The caliber measuring device (18) has on it the end of which has an adapter shoe (16) which is in a bearing sleeve (9) in the sleeve (1) can be used and the Ka Libermeßgerät (18), whose outer diameter is smaller than the diameter of the sleeve bore, in the sleeve centered hole. The caliber measuring device (18) remains there forth from deformations, which the sleeve (1) when Passing through the deep hole is subject. The sleeve (1) is provided with openings (7) through which the arms (26) of the caliber measuring device (18) can be extended. To align the arms (26) with the openings (7), orientation means (11, 15, 20, 22) are provided, the adapter shoe (16) when inserted into the bearing sleeve (9) in its angular position to the sleeve (1) straighten (Figure 1).
