Abstract

An apparatus investigates a technical device using a borescope. The apparatus has: a guide tube which is introducible through a borescope opening on the technical device to be inspected using the borescope; and a repeatedly plastically deformable carrier configured to guide a borescope head arranged at one end of the carrier. The guide tube is designed to deform the carrier during the passage of the carrier through the guide tube.

First claim

The invention claimed is:

1 . An apparatus for investigating a technical device using a borescope, the apparatus comprising:
a guide tube which is introducible through a borescope opening on the technical device to be inspected using the borescope and configured to be arranged on the technical device; and a repeatedly plastically deformable carrier configured to guide a borescope head arranged at one end of the carrier, wherein the guide tube is designed to deform the carrier during the passage of the carrier through the guide tube such that a shape of the deformed carrier when introduced into the technical device is specified by the guide tube arranged on the technical device.

2 . The apparatus as claimed in claim 1 , wherein the carrier is a material composite tube.

3 . The apparatus as claimed in claim 2 , wherein the material composite tube comprises a core consisting of a wound aluminum strip, the material composite tube having an inner side and further comprising a plastic covering or a protective coating on the inner side.

4 . The apparatus of claim 3 , wherein the wound aluminum strip is wound lengthwise.

5 . The apparatus as claimed in claim 1 , wherein the guide tube is designed for fastening to the technical device in a distinct position.

6 . The apparatus as claimed in claim 1 , further comprising a predeforming unit configured to predeform, by twisting or bending, the carrier before the passage of the carrier through the guide tube, wherein the predeforming unit is controllable.

7 . The apparatus as claimed in claim 1 , wherein a drive is provided for the carrier and/or the borescope guided through the carrier.

8 . The apparatus as claimed in claim 1 , wherein the guide tube is adaptively adjustable.

9 . The apparatus as claimed in claim 1 , further comprising a probe configured to determine a position and/or orientation of an introduction end of the carrier and/or of the borescope head at that end of the carrier which is to be introduced into the technical device.

10 . The apparatus as claimed in claim 9 , wherein the probe is integral with the borescope head.

11 . The apparatus as claimed in claim 1 , wherein the borescope head is arranged directly on the carrier or on a flexible borescope shaft which is guidable through the carrier.

12 . The apparatus as claimed in claim 1 , further comprising a controller configured to control a guide tube fastener, a predeforming unit, and/or a drive, taking into account a positional and/or orientational information of an introduction end of the carrier and/or the borescope head, obtained via a probe or by the borescope guided through the carrier.

13 . An assembly comprising the apparatus as claimed in claim 1 and the borescope comprising the borescope head, wherein the carrier of the apparatus has a tubular design and the borescope is introduced into the carrier of the apparatus.

14 . The apparatus as claimed in claim 1 , further comprising a guide tube fastener designed for fastening to the technical device in a distinct position, wherein the guide tube fastener is designed to modify the situation of the guide tube relative to the technical device systematically and controllably.
