Definitions

  • the present invention relates to a fastening device for rails of the type comprising the characteristics expressed in the preamble to Claim 1.
  • the rails that compose tracks are supported by sleepers, made of wood or cement, whereto they are fastened by means of fastening devices.
  • the "Pandrol” device comprises a base element fastened in the sleeper supporting the rail, and having in correspondence with the surface of the sleeper itself a tubular seat in which a first end of the clip is inserted.
  • the rail To carry out its adjustment, the rail must be at least partially free to slide longitudinally, but at the same time it must be held laterally, since a certain number of trains must be made to travel over the track in order to perform a correct adjustment operation.
  • the rail once placed back in service, has in its interior a non uniform tension, with compressed areas alternating with areas under traction.
  • the technical task constituting the basis for the present invention is to obtain a fastening device for rails that overcomes the aforementioned drawbacks.
  • a technical task of the present invention is to obtain a fastening device for rails that can allow the longitudinal sliding of the rail and, at the same time, guarantees lateral grip on the rail itself.
  • a further technical task of the present invention is to obtain a fastening device for rails that allows the temporary substitution of the clip used in "Pandrol" devices.
  • the reference number 1 globally indicates a fastening device for rails according to the present invention.
  • the fastening device 1 comprises a structure 2 in which are mounted a hinging element 3, a contact element 4 and adjustment means 5.
  • the structure 2 has a first and a second end portions 6, 7 and an intermediate portion 8 connected between the two end portions 6, 7.
  • the direction that goes from the first to the second end portion 6, 7 can be defined as a first direction of development of the structure 2.
  • the structure 2 comprises a main plate 9 presenting an upper surface 10 and a lower surface 11 and two shoulders 12, substantially specular relative to each other and positioned facing each other and mutually distanced.
  • Each shoulder 12 is laterally fastened to the plate 9 and develops mainly in a plane parallel to the first direction of development and perpendicular to the lower surface 11 of the plate 9.
  • the structure 2 has at least two through holes 13, mutually coaxial according to a direction of development that is substantially perpendicular to the first direction of development of the structure 2.
  • the through holes are obtained through the two shoulders 12 and develop according to a direction parallel to the lower face of the plate 9.
  • the structure 2 further presents, in correspondence with the second end portion 7, a threaded through hole 14 developing perpendicularly to the plate 9.
  • the hinging element 3 can be pivotally engaged to a hitching element 15 mounted in proximity to a rail, and is mounted on the structure 2 in correspondence with the intermediate portion 8.
  • the hinging element 3 develops substantially transversely to the direction of development of the structure 2 to allow, once associated to the hitching element 15, the oscillation of the structure 2 in a vertical plane passing through the first direction of development.
  • the hinging element 3 is constituted by a first pivot pin 16 removably inserted in the two through holes 13 obtained in the shoulders 12.
  • the first pivot pin 16 has, in correspondence with its own first end 17, an obstruction head 18 whose diameter is greater than that of the through holes 13.
  • the second end 19 of the first pivot pin 16 is further provided with removable obstruction means 20 to prevent the passage of the second end 19 through the holes 13.
  • said removable obstruction means 20 are constituted by a removable pin 21, passing through the second end 19 of the first pivot pin 16.
  • said first pivot pin 16 can be pivotally inserted in a housing 22 which is obtained inside the hitching element 15 mounted in proximity to the rail, and which is constituted by a substantially rectilinear through hole.
  • the contact element 4 is pivotally mounted on the structure 2 in correspondence with the first end portion 6 of the structure 2, and presents an operative face 23 able to be pressed against the surface of the flange 24 of the rail 25.
  • the operative face 23 can be associated in abutting contact against the upper surface 10 of the flange 24 of the rail 25, either directly or through a bearing element 26 which may or may not already be associated to the rail 25.
  • the operative face 23 of the contact element 4 can further present a knurled surface, in order to exert a greater friction against the surface of the rail 5.
  • the adjustment means 5 are mounted on the structure 2 in correspondence with the first end portion 6 and serve to adjust the pressure of the contact element 4 against the rail 25.
  • the adjusting means 5 comprise a second threaded pivot pin 27 able to be screwed through the structure 2 according to a direction of development that is perpendicular both to the first direction of development, and to the main direction of development of the first pivot pin 16.
  • said second pivot pin 27 is screwed in threaded through hole 14 obtained through the first end portion 6 of the structure 2.
  • the fastening device 1 may or may not also comprise the hitching element 15 able to be fastened to the sleeper of a rail 25.
  • fastening means 1 of the present invention is constructed to constitute a wholly autonomous fastening device 1, usable instead of traditional ones, it also comprises the hitching element 15.
  • the fastening device 1 is constructed to be used to replace temporarily the elastic clips of "Pandrol" fastening devices, it lacks the hitching element 15.
  • the fastening device 1 is used in the following way.
  • the fastening device is to be used as an autonomous fastening device 1, the first step is to fasten the hitching element 15 to the sleeper of the rail 25.
  • the hitching element 15 of said device is used.
  • the first step is to extract the first pivot pin 16 from the through holes 13, after removing the removable obstruction means 20.
  • the structure 2 is then positioned on the upper portion of the hitching element 15 in such a way as to align the through holes 13 with the housing obtained on the hitching element itself, and in such a way that the contact element 4 is in correspondence with the flange 24 of the rail 25.
  • the first pivot pin 16 is then inserted through the holes 13 and the housing, and the removable obstruction means 20 are positioned.
  • the structure 2 is in the condition to be able to rotate about the first pivot pin 16, relative to the hitching element 15 in a substantially vertical plane.
  • the pressure exerted by the contact element 4 on the flange 24 of the rail 25 can be adjusted.
  • the present invention achieves important advantages.
  • the fastening device for rails of the present invention allows, by adjusting the pressure of the contact element against the flange of the rail through the adjustment means, the longitudinal sliding of the rail, whilst guaranteeing the lateral immobility of the rail itself.
  • the fastening device for rails of the present invention can therefore be used to replace temporarily the clips of "Pandrol" devices during the adjustment operations of long welded rails.
  • the fastening device of the present invention can be used in a wholly autonomous fashion instead of the fastening devices in use today, also because it is relatively easy to produce and its cost is not very high.
