The invention relates to an instrument holder for the inspection of a dynamo-electric machine having a stator (1) and a rotor (2) in which the rotor (2) is somewhat cylindrically arranged around a main shaft (3) and can rotate about it and is fitted in a cylindrical recess in the stator (1) in relation to the main shaft (3) leaving a gap (4). The instrument holder can be inserted and moved in the gap (4) along the main shaft (3) and comprises the following components: a frame component (5) circularly surrounding the main shaft (3) to which can be secured means (6, 7, 8) for making the inspection, a plurality of rollers (9) which, looked at in a plane perpendicular to the main shaft (3), are mutually staggered and each of which is secured to the frame component (5) to be rotatable about an appropriate axis of rotation (10), the axis of rotation (10) being substantially perpendicular to the main shaft (3). The instrument holder can be inserted into the gap (4) without removing the rotor (2) and can be fitted with any instruments and auxiliaries for performing the inspection. It can be moved in the gap (4) without any risk of jamming as it is directly supported on the stator. |
