ABSTRACT:
The invention relates to an apparatus for survey and/or treatment of a smooth curved surface.
The apparatus comprises a vehicle able to be moved on the surface along a predetermined path, the vehicle being provided with abutment means movable with respect to the body of the vehicle. A support arm of the vehicle is fixed to this by a swivel pivot point. The support arm is fixed close to the center of curvature of the curved surface. The axes of the abutment means and of the arm of two supports can be oriented to be substantially concurrent in the vicinity of the center of curvature of the curved surface. Means for survey and/or treatment of the curved surfaces are fixed to the vehicle. Means for control of driving of the vehicle and of the survey and/or treatment means are also provided.
Application to the survey and to the maintenance of water boxes of steam generators of electo-nuclear power stations.
