Patent ID: 7305898

Claim:
An installation for non-destructive inspection of a rotor-forming part having an axis of revolution and including annular cavities axially adjacent to one another, the installation comprising a sensor support suitable for moving over a surface of said rotor-forming part to be inspected, and means for combining circular displacement and radial displacement of said support and/or of said rotor-forming part, and said support being fitted with a plurality of sensors for sensing different physical characteristics in order to pick up data groups specific to said sensors, and corresponding to respective defined zones of said surface, in a single scan thereof, wherein said rotor-forming part includes a common space extending axially between said annular cavities, the installation including a horizontal turntable on which said rotor-forming part can be placed for inspection, a vertical column movable above said turntable and arranged to engage in said common space of said rotor-forming part for inspection, a chain of locking links mounted to slide along said column, and a deflector carried by said column and comprising an angled guide duct for said chain, presenting a lateral outlet through which the chain leaves substantially horizontally in the form of a rigid segment having links blocked mutually one against another, the end of said rigid segment being connected to said sensor support to move said sensor support while facing a surface for inspection of said rotor-forming part.
