Definitions

  • the subject of the present invention is a spacing device and more particularly a lifting device making it possible to spread or lift parts and particularly when they have a very small space between the bearing faces.
  • the following description of the invention relates to the case of its application for lifting parts; this is only a special case, the use of the device also being valid link, the use of the device also being valid for enlarging the distance between two neighboring elements.
  • the present invention consists of a device capable of both lifting heavy parts and usable even when the space between the bearing surfaces - the ground, for example, and the part to be lifted is small.
  • the operating principle of the device of the invention lies in driving a wedge between the two bearing surfaces, penetration being facilitated by the presence of two sliding surfaces.
  • Figure 1 is an elevational view of the device in its starting position, that is to say when it will be used to lift a part;
  • Figure 2 is a cross section of the device;
  • Figure 3 is an elevational view of the device when the elevation height of the part to be lifted is reached;
  • Figure 4 is a plan view.
  • the cylinder (4) and the sheets (2) and (3) are connected by means of connecting rods (7) and (8) which prevent the movement of the sheets under the thrust of the jack and also allow the spacing or the approximation of said sheets relative to each other by rotation about the articulation pivots (9) (9 '), (10) and (10').
  • the two sheets (2) and (3) are kept in permanent contact with the corner (1), even in a situation of non-activity of the device, by means of elements such as springs stretched between the articulation pivots (10) and (11) and (10 ') and (11').
  • FIG. 2 which shows a cross section of the device at the location of the articulation pivots (10) and (11); we can clearly see the corner (1) and the U-shaped sheets (2) and (3); the flat inner faces of said sheets are in contact with the inclined flat faces of the corner.
  • Articulation pivots are fixed to the wings of the sheets (10), (10 ') (11) and (11') to allow the rotation of the connecting rods, (7), (7 ') and (8), (8' ) in the case shown.
  • Figure 3 shows, in elevation, the device of the invention when the jack (4) has inserted the corner (1) into the space - now the height e2 - between the ground and the part to be lifted; we note that the beak (15) of the corner is out of its housing between the two sheets, that the sheet (2) which is not in contact with the ground has moved away from the sheet (3) without contact between the sliding surfaces of the corner and the sheets has been broken, thanks to the play of the connecting rod (7) which allowed the upward movements of the sheet (2).
  • Figure 4 which shows in plan the device of the invention in the situation after lifting corresponding to Figure 3 (corner beak out), there are again the beak (15) of the corner, the sheet (2) connected to the cylinder (4) by the connecting rods (7) and (7 '). Said connecting rods being able to undergo rotation around the articulation pivots (10) and (10 ') on the one hand, (9) and (9') on the other hand.
  • the angle and length of the corner can be determined depending on the application.
  • the lifting force can reach 12 tons, but the invention also makes it possible to use other more powerful cylinders or double-acting cylinders.
  • the advancement of the corner can also be done mechanically with a screw. Between the pivots which hold the support plates to the connecting rods, the 2 sheets can be kept in contact with the corner by springs fixed to the screws, but any other form of support can be provided, such as, for example, rubber rings.
  • the outside faces of the support plates can be ribbed or grooved to increase adhesion with the ground or the part to be lifted.
  • the spacing device and more particularly the lifting device, object of the present invention is thus essentially characterized in that it comprises an inner part in the form of a corner, the two inclined faces of said corner being each covered by a U-shaped sheet, the inner face is in contact with the corresponding inclined face of the corner that it covers, a pushing system of the corner between the two sheets towards elements to be separated or the part to be lifted and means for connecting the sheets to the pushing system of the corner, comprising pivots of articulation of the sheet around an axis parallel to the plane of the inclined faces of the corner.
  • the device also comprises elastic means for holding the U-shaped sheets in contact with the inclined faces of the corner.
