## Abstract

A device for the treatment of a surface, such as a flat and/or curved surface, the device including at least one surface treatment tool mounted onto a secondary motorized carriage capable of moving along a rail between two primary carriages that can move along tubes, preferably parallel, straight or curved. The primary carriages are mounted onto the rail, on the one hand, in such a way as to rotate around an axle that is orthogonal to the rail and, on the other hand, in such a way as to slide along the rail.

## Claims

### Claim 1

A surface treating device, said device comprising at least one surface treatment tool mounted on a secondary motorized carriage capable of moving along a rail between two primary carriages that can move along tubes, characterized in that the primary carriages are mounted on the rail in such a way as to rotate around an axle that is orthogonal to said rail and in such a way as to slide along said rail.

### Claim 2 (depends on 1)

The surface treating device according to claim 1, characterized in that each primary carriage contains a roller mounted pivotally in relation to the axle integral with said primary carriage and extending within a longitudinal guide formed with the rail.

### Claim 3 (depends on 1)

The surface treating device according to claim 1, characterized in that the primary carriages are motorized and comprise drive mechanisms capable of resting on the tubes, and rolling along said tubes in order to move said primary carriages.

### Claim 4 (depends on 3)

The surface treating device according to claim 3, characterized in that the drive mechanisms consist of a track extending between two sprockets.

### Claim 5 (depends on 4)

The surface treating device according to claim 4, characterized in that the drive mechanisms contain at least one roller held against an inner wall of the track by a spring in order to tension the track.

### Claim 6 (depends on 4)

The surface treating device according to claim 4, characterized in that each track has a flat inner wall and an outer wall with a concave cross-section in order to accommodate a diameter of the tube.

### Claim 7 (depends on 4)

The surface treating device according to claim 4, characterized in that at least one of the sprockets is driven in rotation by a motor.

### Claim 8 (depends on 1)

The surface treating device according to claim 1, characterized in that each primary carriage consists of at least two boxes extending in parallel to one another and connected by a spacer, one of the boxes being hinged onto the rail and each box containing a drive mechanism, at least one of which is motorized.

### Claim 9 (depends on 1)

The surface treating device according to o claim 1, characterized in that said tool consists of a hydroblasting head.

### Claim 10 (depends on 9)

The surface treating device according to claim 9, characterized in that the hydroblasting head comprises a cylindrical housing within which extends a rotating nozzle with holes, said nozzle being fed with water under high pressure by way of a flexible pipe so as to form jets at the outlet of the holes.

### Claim 11 (depends on 10)

The surface treating device according to claim 10, characterized in that the lower edge of the housing comprises a brush that ensures a seal when the hydroblasting head is pressed against the surface to be treated.

### Claim 12 (depends on 10)

The surface treating device according to claim 10, characterized in that said hydroblasting head contains suction pipes connected to a suction source and leading into the housing.
