Device for checking a turbomachine engine
View Patent ↗A device for non-destructive in situ inspection of parts of a turbine engine, the device including a stick carrying at its distal end a pivoting finger carrying at one of its ends a blade for supporting an inspection probe, and at its opposite end a skid for bearing against and/or catching on an element of the engine, the skid being movable in a direction parallel to the longitudinal axis of the finger.
1. A device for non-destructive in situ inspection of parts of an engine, the device comprising:
a longitudinal stick including an inspection probe mounted at a distal end thereof; and
a longitudinal finger pivotally mounted to the distal end of the stick, the finger carrying at a first end support means for supporting the inspection probe, and at a second end catch means for catching on an element of the engine, the catch means being movable in a direction parallel to the finger.
2. A device according to claim 1 , wherein the support means comprises a blade of elongate shape that is pivotally mounted via one of its ends to the first end of the finger to pivot between a folded position in which it extends substantially parallel to the finger and a deployed position in which it extends substantially perpendicularly to the finger.
3. A device according to claim 2 , wherein the blade is elastically deformable in bending.
4. A device according to claim 2 , wherein the inspection probe is fastened to the free end of the blade.
5. A device according to claim 2 , further comprising resilient return means urging the blade towards its folded position or its deployed position.
6. A device according to claim 2 , further comprising at least one control cable for controlling pivoting of the blade from its deployed position to its folded position and/or from its folded position to its deployed position, the control cable(s) extending along the stick.
7. A device according to claim 1 , wherein the finger is pivotally mounted in its middle portion to the distal end of the stick, to pivot between a folded position in which it extends substantially parallel to the stick and a deployed position in which it extends substantially perpendicularly to the stick.
8. A device according to claim 7 , further comprising resilient return means urging the finger into its folded position or its deployed position.
9. A device according to claim 7 , further comprising at least one control cable for controlling pivoting of the finger from its deployed position to its folded position and/or from its folded position to its deployed position, the control cable(s) extending along the stick.
10. A device according to claim 1 , wherein the catch means comprises a rod that is slidably mounted in a corresponding axial recess in the second end of the finger and that carries at its free end a bearing tab that extends substantially perpendicularly to the rod.
11. A device according to claim 10 , wherein movement of the catch means is controlled by at least one cable extending along the stick and connected at its distal end to the end of the rod that is opposite from the bearing tab.
