Definitions

  • the present invention relates to a device for fixing a running rail, and in particular to a device for fixing a running rail subjected to very heavy loads such as a rail for crane or harbor crane.
  • the present invention also relates to the parts constituting said fixing device, and covers by extension any system comprising said device, and in particular which comprises at least said device and the running rail.
  • the present invention also relates to the method of manufacturing such a device.
  • Rail fasteners such as roller rails are well known. They are preferably used in pairs, the devices of each pair being disposed opposite each other, on each side of the pad of said rails, to fix them to the surface of a support, preferably flat.
  • fasteners there are two types of fasteners, fasteners to bolt and fastening systems to weld.
  • the present invention is more specifically in the framework bolt fasteners, and more specifically still within the so-called flexible fastening devices.
  • fixing clips consist of at least two elements, called “primary element” and “secondary element”.
  • the "primary element” generally comprises two pieces.
  • the first piece is supported on the support and is firmly attached to it.
  • the second part makes it possible to trap the rail, and more particularly the soleplate or the runner of the rail, for example by having an overhanging lateral surface coming into contact with the soleplate or the runner of the rail.
  • the "secondary element”, which defines here the type of fastener, is a means for fixing the first and second parts together. In general, it comprises at least one screw whose head is inserted into an opening in the first and the second element and on which is fixed a nut. More generally, the term “secondary element” includes all fasteners, including in particular the washer or washers that may be associated therewith.
  • the lateral surface of the second piece of the primary element may have an elastomer nose.
  • This nose allows a certain vertical flexibility, particularly suitable for the absorption of stresses induced by the passage of rollers of rolling vehicles on the rail.
  • the rail is not completely clamped, since it is held laterally firmly but retains the ability to move vertically in certain proportions.
  • the primary element may also consist of only one piece, the screw (secondary element) then to pass through the support on which this piece rests.
  • the support which is most often a metal beam, can be drilled for this purpose.
  • interlayer a continuous rubber strip that is placed under the support of the rail, together with that of these clips, contributes to ensure, under operating conditions, a certain vertical flexibility of the rail and thus obtain a fixation flexible rail.
  • this solution is particularly advantageous in the case of large loads or in the case of particularly severe use rates as in the case of continuous operation of cranes.
  • cranes and cranes are at the same time heavier, taller and more bulky than before. In addition, they move and work faster. Comparatively, the number of wheels and their diameters do not increase in proportion, which has the effect of increasing the wheel load of cranes and cranes.
  • the vibrations cause a rotation of the rail, which causes tensions and clearances in the fastening systems and thus wear or even unscrewing parts.
  • the present invention aims to propose a solution that overcomes some or all of the disadvantages mentioned above.
  • the present invention aims at providing a fixing device comprising a new clip and a suitable screw and which could be used for cranes and / or cranes with particularly high loads, and in particular greater than 100 tons.
  • Another object of the invention is to provide a fixing device that is easily and simply mountable / removable while providing maximum safety.
  • the present invention aims at providing a device for fixing minimal space.
  • the inclination of the screw itself has the effect of sliding (pushing) the primary element towards the rail.
  • the idea therefore of the present invention is to design a fixing device which, once mounted, exerts not only a substantially vertical force on the screw (perpendicular to the plane of the support), but tends to reveal a new component, preferably horizontal, so as to tilt the screw (bend) towards the rail and thus to slide the primary element towards the rail.
  • the axis of the upper box and the axis of the lower box are merged (same common central axis for the two boxes).
  • the tilting means (the tilting element) form an integral part of the upper surface of the part.
  • the tilting means correspond to one or more different (s) of the piece constituting the primary element.
  • the tilting element (the positioning means) can (can) take different forms.
  • the tilting element can thus for example take the form of a bulge present on the edges of the upper surface of the workpiece.
  • the tilting member may also take the form of a spring present on the edges of the upper surface of the workpiece.
  • tilting means such as in particular a set of wedged wedges or a compressible wedge.
  • the lower box (box on the bottom surface) of the part includes stops designed to lock the head of the screw when the device is mounted.
  • said stops are further inclined at a certain slope inclination relative to the plane of the upper surface which is parallel to the inclination slope of the shim.
  • the inclination means of the screw also comprise said stops which are inclined at a certain slope inclination parallel to the slope of inclination of the tilting element.
  • the upper surface of the component constituting the primary element comprises a portion which protrudes beyond the lower surface of said piece and is adapted to come into contact with the sole of the rail when the device is attached to the rail.
  • said portion has a flexible member, preferably an elastomer, designed to make contact with the sole of the rail when the device is attached to the rail.
  • a flexible member preferably an elastomer

  • the portion of the upper piece is not in direct contact with the bottom piece.
  • the lower box has an insertion zone, through which the screw is introduced into the box in an initial position, and a clamping zone, corresponding to a final position of the screw which allows the locking and clamping of said screw, when it is positioned there.
  • the passage of the screw in the lower box of the zone of introduction to the clamping zone is made by rotation.
  • the passage of the screw in the lower box of the zone of introduction to the clamping zone is done by translation.
  • the passage of the screw in the lower box of the introduction zone to the clamping zone is by rotation and translation.
  • the lower chamber of the workpiece includes stops located at the clamping zone (21) and adapted to lock the screw head when the device is mounted.
  • the passage of the screw in the lower box (8 ') of the zone of introduction to the clamping zone can be done either by rotation, by translation, or by rotation and translation.
