Definitions
- the present invention relates to a spacing device and more particularly to lifting per ⁇ putting aside or lifting parts and particularly when they have a very small space between the bearing faces.
- spacers comprising jaws articulated by a jack; given the thickness that these jaws must have in order to withstand significant forces, these spacers can only be used if there is sufficient space between the two bearing faces. Due to their design, they only allow to lift small loads at the end of the hooks.
- 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 support 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 jack (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 on the other hand allow l 'deviates between 5 or the bringing together of said sheets one in relation to the 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 wedge (1), even when the device is inactive, by means of elements such as springs stretched between the pivots d 'articulation (10) and (11) and (10 1 ) and (11').
- FIG. 2 which represents a cross section of the device f 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 interior faces pianos dcsciit.es Liers are in 0 contact with the inclined plane faces of the corner.
- -Article pivots are fixed to the wings of the sheets (10), (10 '), (11) and (11 1 ) to allow the rotation of the connecting rods, (7), (7') and (8) , (8 ') in the case shown.
- the angle and the length of the corner can be determined according to the application.
- the lifting force can reach 12 tonnes, but the invention also makes it possible to use other more powerful jacks or double-acting jacks.
- the advancement of the corner can also be done mechanically with a screw.
- the 2 sheets can be kept in contact with the wedge by springs fixed to the screws, but any other form of support can be provided, such as, for example, rubber rings.
- the outer faces of the support plates can be striated or grooved to increase adhesion with the ground or the part to be lifted.
- the spacing and more particularly lifting device, object of the present invention is thus essentially characterized in that it comprises an inner part in the form of a wedge, the two inclined faces of said wedge being covered each with a green U-shaped sheet whose inner face is in contact with the corresponding inclined face of the corner which it covers, a thrust system of the corner between the two direct sheets tion of the elements to be removed or the part to be lifted and means for connecting the sheets to the corner thrust system, comprising pivots for 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.
- the wedge thrust system is constituted by a hydraulic cylinder; also according to the invention, the means for connecting the thrust system from the corner to the U-shaped sheets consist of connecting rods.
- the elastic means for holding the U-shaped sheets in contact with the inclined fa ⁇ of the corner consist of springs, preferably fixed to the articulation pivots. sheets.
- the articulation pivots of the upper sheet can be fixed either in the wings of the sheet, or in an integral housing and located above this sheet.
- the U-shaped sheets can advantageously be extended by flat sections in the form of spouts, ensuring the protection of the corner during its movement.
