  • the device considered comprising a support for the object to be moved in the vicinity of the surface, comprising at least two guide rollers engaged respectively in one and the other of two separate grooves forming rails, formed in a support structure on the ground, mobile and disposed as close as possible to the surface, this structure having a profile corresponding substantially to that of this surface, the two rollers being arranged in their respective grooves so that they are always separated by a invariable distance, control means being provided for moving the rollers in their grooves, is characterized in that the grooves receiving the rollers are open towards the outside and provided on either side of an upright belonging to the structure d 'support, these grooves having different profiles which are a function of the curvature of the surface and arranged so that the line joining the rollers always remains parallel it itself when these rollers describe the grooves under the action of control means, forming a constant angle with a given reference line of the support of the object.
  • the angle formed by the line joining the rollers and the reference line of the support is close to 45 °.
  • the invention notably consists in giving the profiles of the grooves receiving the rollers respective curvatures adapted to precisely obtain that the aforementioned angle remains permanently constant, the reference line of the support of the object therefore remaining always parallel to itself.
  • the grooves are arranged in such a way that they can cross each other in space without the risk that they can directly interfere with each other due to their distinct positions, on either side of the upright. who has them.
  • the object support is constituted by a flat plate, crossed by a first and a second transverse shafts, the first shaft being rotatably mounted and the second being immobilized relative to the plate, the guide rollers being secured to the ends of these two trees.
  • the device comprises four guide rollers, respectively arranged in pairs at the ends of the two transverse shafts, these rollers being associated two by two in open grooves, provided respectively on two uprights of the support structure, parallel to each other and arranged on each side of the plate.
  • one of the rollers is mounted and stopped at the end of the first rotary shaft and is associated with a control pinion for moving the plate, also keyed onto the shaft and arranged in a parallel plane to that of the roller, this pinion driven by a motor carried by the plate meshing with a chain or toothing mounted and immobilized in the bottom of the groove receiving this roller.
  • the other roller is mounted idly on an axis parallel to the second shaft and is carried by a crank pin, itself secured to the end of this shaft, this crank pin being wedged on this shaft with a fixed fixed orientation, defining, in combination with the position of the two shafts on the plate, the invariable distance between the two rollers.
  • each lateral upright of the support structure comprises a central metal plate, on the opposite faces of which are welded or otherwise fixed curved U-section profiles, delimiting the open grooves receiving the rollers with a clearance inside these grooves canceling out depending on whether the roller rolls on one or the other of the opposite sides of the profile, depending on the direction of movement of the object support with respect to the support structure.
  • the tray supports a protective nacelle for an operator, moving according to the height of the structure relative to the surface.
  • the support structure is mounted on wheels so that it can be moved on the ground and spread or approached as close as possible to the surface.
  • the support structure comprises means for immobilizing the ground and possibly means for tilting its uprights so that they can be brought into the immediate vicinity of the profile of the surface.
  • the reference 1 designates the external surface of any part 2 of large dimensions of the box, tank or other type, which it is desired to follow by means of any object, in particular a tool or a control device (not shown) to control the profile or intervene thereon.
  • the structure 3 comprises a base 7, preferably having a U-shaped profile whose lateral sides, respectively 8 and 9, are provided with wheels, 10 and 11, making it possible to move the structure on the ground 4 in combination with a third wheel 12 mounted at the end of a middle arm 13, extending parallel to the lateral sides 8 and 9 substantially at the center of a connecting beam 14 provided perpendicularly between these sides.
  • the wheels 10 and 11 are provided with an appropriate locking system (not shown) once the structure has been properly placed in front of the surface 1 of the part 2, a jack 15 being also provided in the vicinity of the central wheel 12 so to immobilize the assembly in the final position.
  • the base 7 comprises a transverse axis 17 on which the support structure 3 itself is articulated, the latter preferably comprising two lateral uprights, respectively 18 and 19, extending in two vertical planes parallel to the lateral sides 8 and 9 of the base 7.
  • Cylinders 20 are provided between the base and an appropriate point of articulation on the uprights 18 and 19 so as to make it possible to raise or to lower the latter properly in order to arrange the structure as close as possible to the surface 1, the uprights presenting by construction a profile whose curvature is substantially similar to that of the surface 1 so as to partially envelop the latter, as shown diagrammatically the elevation view of Figure 1.
  • the support plate 5 with its nacelle 6 is provided, in accordance with the invention, to move along the uprights 18 and 19 of the support structure 3, always remaining parallel to itself and in particular in the example considered, still horizontal, the cantilever of the nacelle relative to the structure being usefully balanced thanks to a counterweight 21 disposed on the base 7.
  • the plate 5 is supported on each of its lateral sides by two rollers, respectively 22 and 23, each engaged in a groove 24 or 25, these grooves being arranged on the uprights 18 and 19 of the structure in a manner which will be described below.
  • FIG. 3 shows in more detail the production of the plate 5 and the mounting thereon of the guide rollers 22 and 23.
  • This plate is in particular provided with a first rotary shaft 26, freely crossing the sides of the plate and swiveling by relative to the latter in support bearings (not shown), the shaft 26 comprising at each of its ends projecting from the lateral sides of the plate towards the uprights 18 and 19 respectively a roller 22.
  • Each of the rollers 22 is also associated to a pinion 27, keyed onto the shaft 26 and disposed in the immediate vicinity of the roller in a plane parallel to the latter, a similar arrangement being naturally provided at the opposite end of the shaft 26.
  • the plate 5 also comprises, extending parallel to the rotary shaft 26, a second shaft 31, also passing through the plate but which is immobilized relative to the latter, by welding or other suitable fixing means.
  • a crank pin 32 At each end of the shaft 31, projecting from the lateral sides of the plate, is fixed a crank pin 32 whose orientation is determined by construction, in particular with an appropriate inclination so that the roller 23, mounted freely on an axis 33 provided on the crank pin opposite the shaft 31 and parallel to it, is spaced from the roller 22 carried by the shaft 26 by a determined distance remaining invariable, regardless of the position of the plate on the support structure .
  • the shaft 31 supports at its opposite end another roller 23, mounted on a similar crankpin, so as to be disposed vis-à-vis the homologous roller carried by the shaft 26 in an exactly identical position.
  • rollers 22 and 23 are respectively mounted in the grooves 24 and 25, provided in the uprights 18 and 19 and arranged thereon according to an arrangement that Figures 4, 5 and 6 make it possible to explain more clearly. detailed.
  • cross sections of one of the uprights appear at different levels thereof, here the upright 19, it being naturally understood that exactly similar and symmetrical arrangements of the first are implemented on the upright 18.
  • Each of the uprights 18 and 19 comprises in particular a central plate 34, extending in a vertical plane and against the opposite surfaces of which the grooves are arranged, 24 and 25 respectively, these receiving the rollers 22 and 23.
  • the groove 24 comprises in addition, to the right of the gable 27 associated with the roller 22, a toothing or chain 35, immobilized or otherwise fixed in the bottom of the groove so as to allow, when it cooperates with the pinion, to ensure by reaction the movement of the plate 5 relative to the support structure 3.
  • the roller 23 is for its part engaged in the second groove 25, the two rollers 22 and 23 forming with the side walls of the grooves 24 and 25 against which they bear games 36, which are specific to cancel each other depending on whether the corresponding roller rolls on one or the other of these walls.
  • each groove is delimited by means of a profile 37, which has come from manufacturing or attached and welded to the flat 34, the shape of these profiles being such that the open grooves 24 and 25 which they thus delimit, cross in the space according to the height of the support structure, without naturally interfering with each other since they each remain arranged on one and the other of the two opposite faces of the central plate 34.
  • the proposed structure can by construction be easily produced so as to present itself a profile partially surrounding the part or the work whose surface is to be followed or controlled, the curvature of the grooves receiving the rollers being determined so as to ensure invariance in the space of the plane of the plate and as a result of the relative orientation of the two guide rollers, the angle chosen between these two directions being determined to best pick up the moments of bending which are exerted on the structure according to the successive positions of the plate on the structure.
  • the invention is not limited to the embodiment more specifically described and shown above; on the contrary, it embraces all its variants.
  • the shape of the uprights of the support structure could be easily adapted to any profile of the surface to be followed, the latter possibly having successive concave or convex parts, the grooves crossing each other as much times necessary to maintain always equal to itself the angle of the reference line of the plate and the relative direction of the two guide rollers.
