Definitions

  • the present invention relates to a noise-reducing device of a rail for railway vehicles comprising a jacket of elastic material, said jacket comprising two parts intended to extend on either side of the rail, in particular a trolley rail, on the one hand, for wrapping the two lateral flanks of this rail, and, on the other hand, for positioning said rail in a channel formed in a solid material, in particular prefabricated or cast concrete, the elastic material being sufficiently rigid for that the two aforesaid parts can maintain the rail in position during the passage of a vehicle on the rail.
  • One of the essential aims of the present invention is to propose a simple solution that makes it possible to remedy this important drawback.
  • the anti-noise device comprises fastening means comprising a removable clamping element for applying the two aforesaid parts in the channel against said lateral flanks of the rail, so as to fix the rail in the channel and release the rail in the latter by eliminating the clamping element.
  • the clamping element comprises a band of reinforced elastic material positioned in a slot parallel to the lateral flanks of the rail provided in the channel on the side of one of the elastic parts opposite to that oriented towards the rail in such a way as to be able to on the one hand, be removed from the slot to release the rail and, on the other hand, be forced into the slot to secure the rail.
  • the channel has side walls substantially parallel to the lateral sides of the rail, a recess oriented towards the latter being provided in each of these walls, one of the parts elastics that can penetrate into the hollow of one of these walls, the clamping element being engageable in the hollow of the other wall.
  • the rail rests on a sole of elastic material located on the bottom of the channel.
  • Figure 1 is a perspective view of a portion of a railway provided with an anti-noise device according to a first embodiment of the invention.
  • Figure 2 is, on a larger scale, a section along the line II-II of Figure 1.
  • FIG. 3 is, on a larger scale, a section of the anti-noise device with a rail along line III-III of FIG. 1.
  • FIG. 4 is a perspective view of a part of the noise protection device with a rail according to the first embodiment of the invention.
  • FIG. 5 is an exploded view of the device of FIG. 4.
  • Figure 6 is also a section similar to that of Figure 3 of another embodiment of the invention.
  • Figure 7 is also a section similar to that of Figure 3 of yet another embodiment of the invention.
  • the invention relates to a noise-reducing device for rails for railway vehicles.
  • This device is housed with the rail in a channel and comprises a jacket of elastic material consisting of two parts intended to extend on either side against the two lateral sides of a rail so as to surround these flanks.
  • This elastic material is sufficiently rigid and is for example formed of rubber granules bonded together by an elastomeric resin, in particular polyurethane.
  • the jacket is applied with sufficient force against the sidewalls of the rail to maintain the rail in position when a vehicle passes on this rail.
  • this force is achieved by fastening means comprising a removable clamping element extending over the entire length of the rail and firmly applied against the outer face of the jacket in the direction of the flanks of the rail.
  • fastening means comprising a removable clamping element extending over the entire length of the rail and firmly applied against the outer face of the jacket in the direction of the flanks of the rail.
  • Figures 1 to 5 show a first embodiment of the noise protection device according to the invention.
  • the jacket consists of two parts 1 and 2 separated elastic material of parallelepiped right look extending on either side of a rails 3 against the side flanks 4 and 5 of the latter.
  • This elastic material is of the same nature as that referred to in the patent European EP 0 854 234 B1 as well as in the international patent application WO 2006/032684 A1 .
  • This channel 6 is bordered on either side of the rail 3 by walls 7 and 8 extending parallel to the lateral sides of the latter made of an elastic material whose rigidity is, for example, somewhat greater than that of which is constituted the jacket.
  • the walls 7 and 8 each have a recess 10 and 11 facing the rail 3 along their entire length.
  • the clamping element 9 is somewhat curved on the lateral faces so that this element 9 can engage in the hollow 10 of the wall 7 and in a corresponding hollow 10 'provided in the part 1 of the jacket.
  • the elastic portion 2 enters the recess 11 of the wall 8, under the action of the clamping element 9 which engages in the recess 10 of the wall 7.
  • the rail 3 rests on a sole of rigid elastic material 12 located on the bottom of the channel 6.
  • Concrete 23 is then cast around the walls 7 and 8 and the sole 12 so as to form the channel 6 containing the rail 3 and the two parts 1 and 2 of the elastic material of the jacket, reserving on both sides rail at regular distances from recesses 21.
  • the parts 1 and 2 of the jacket and the clamping member 9 extend to the recess 21 so that in this recess 21 the rail 3 and accessible.
  • the recesses 21 give, in particular, access to the rail 3 for cutting it by means of a saw and removing the rail end between two recesses after eliminating the clamping element 9.
  • the recesses 21 also provide access to this element 9 so as to be able to push it out of the slot between the wall 7 and the part 1 of the jacket.
  • This clamping element 9 is, in particular, manually removed with appropriate material, such as a presser foot or a lever, which is inserted into the space below the clamping element 9 and accessible by the obviously 21.
  • FIG. 6 relates to a second embodiment, according to the invention, which is essentially distinguished from the first by the nature of the clamping elements 9.
  • the clamping elements 9 comprise Z-shaped bearing profiles 15 threaded onto spaced vertical threaded rods 16 secured by their lower end to a base 17 on which the rail 3 is supported by means of a sole 12.
  • the profiles 15 can be subjected to a downward movement and thus act on the upper surface of the two parts 1 and 2 of the jacket to compress them and apply them firmly against the sidewalls. 4 and 5 of the rail 3.
  • An L-shaped protection profile 19 covers the upper end of the threaded rod 16 and is fixed thereto by a screw 20.
  • Concrete 23 is then cast around the assembly formed by the rail 3 and the jacket 1, 2 to the level of the upper surface thereof, so as to form a channel 6 containing the rail 3 with the jacket 1, 2.
  • FIG. 7 relates to a third embodiment of the invention which differs essentially from the previous embodiments in that the channel 6 has a trapezoidal cross section in such a way as to gradually narrow towards the bottom thereof and thus to present inclined plane walls 7 and 8.
  • the clamping elements 9 may for example be of the same kind as in the second embodiment.
  • the clamping element 9 may be formed by a flat, long and narrow profile 15 'fixed by screws 18 on the concrete edges 22 delimiting the channel 6 and protruding relative to the latter. taking support on the upper face of the jacket. As a result of the force exerted by the section 15 'on the parts 1 and 2 of the jacket they are pushed against the lateral flanks 4 and 5 of the rail 3 and the latter is held in position during the passage of a vehicle on the rail.
  • the parts made of elastic material can be of very varied shapes. It is the same for the other components of the noise protection device.
  • the clamping element can be formed by a band of elastic material armed with a metal grid extending along the median plane of the band.
  • the jacket can be formed in one piece, the two parts can, in this case, be hinged to one another so as to be able to undo the rail.
  • the side walls provided in the channel on either side of the rail need not be perpendicular but may be slightly curved thus forming a hollow oriented towards the lateral sides of the rail.
