Definitions

  • the invention relates to a solution, which comprises the fastening of rails on sleepers by resilient clips.
  • the invention belongs to the field indicated under E 01 B 9/28.
  • the fastening of rails on sleepers is a very time consuming, hard and responsible work, which requires the engagement of a large number of workers or the use of very specialized machinery.
  • the fastening of rails on sleepers is carried out in practice on the location itself, where the fastening by sleeper screws is a very time consuming job, while the quality and firmness of the connection as carried out is very hard to be examined.
  • Such a weakening of the connection between a sleeper and a rail is potentially a great risk for the safety of the railway traffic. Examination of the connection firmness, and checking whether the clip generates the prescribed pressure on the rail is almost not allowable or feasible.
  • the further disadvantage of such a solution comprises the fact that the clip makes pressure on the rail in one spot only, so as the time passes, and due to heavy loads and vibrations, the clip becomes deformed at such a spot, loosing its pressure force.
  • This solution contains deficiencies also when using the insulation material between the clip and the rail, which may become thinner and even broke by the time. It is practically impossible to control every clip used on a route. Dismounting as well as mounting is for the mentioned reasons very slow and inconvenient.
  • the further solution known under the title “SKL system” is described in the patent file U.S. Pat. No. 5,096,119, and is also using spring round steel.
  • the solution consists of a clip, made of round spring steel, bent into the modified letter “M”, and a tie-plate.
  • the connection between a rail and a sleeper is achieved by screwing a sleeper screw through a clip and a tie-plate into the sleeper.
  • One part of the clip makes pressure on the tie-plate, lying on the sleeper, and the other part of the clip makes pressure on the rail.
  • the pressure of the clip on the rail is achieved through two spots, and disadvantages of such a connection are similar to the ones indicated in the previous example.
  • the mounting and dismounting are carried out very slowly, because every screw has to be screwed or unscrewed, requiring stopping intervals at each sleeper.
  • a metal plate of trapezoid form serves as a clip, lying with its wider end on the track, ensuring thereby even distribution of the pressure force. After installing a rail, the metal plate is put in its final position. This solution allows pre-assembling. Dismounting is still time consuming, because every screw has to be unscrewed individually enabling the clip to be removed from the bedding, and finally the rail to be removed itself.
  • a solution to the problem comprising the fastening of rails on sleepers and their dismounting is carried out according to this invention by a metal pressure plate—a clip, in the form of trapezoid and a plastic tie-plate.
  • the metal pressure plate-clip and the plastic tie-plate form an entirety, which allows pre-assembly of the entire assembly in the factory, and subsequent incorporation of a rail on the spot.
  • the form of the metal pressure plate-clip ensures a continued pressure along the entire edge, providing a firm and reliable connection.
  • the edge leaning against the rail is formed in the way to allow smooth gliding along the base of the rail during pulling on, and prevents unnecessary resistance and damage.
  • the other side of the pressure plate is formed in the way to prevent any shifting, after the plate is pulled on the rail and the mounting is finished.
  • the plastic pressure plate has a groove on its outer end, in which enters a narrower, outer end of the pressure plate. The groove is formed in the way that it forms a firm connection with the outer end of the pressure plate, preventing the pressure plate to be taken out.
  • the tie-plate also contains one bigger groove, which allows deformation of the pressure plate and the dismounting thereof.
  • the coloured edge of the tie-plate allows a very simple and quick visual checking and establishing whether all the pressure plates are put on correctly to the rail base, which prevents the waist of time on the control of every screw and pressure plate.
  • FIG. 1 A fastening assembly in a pre-assembled condition
  • FIG. 2 A fastening assembly in an assembled condition
  • FIG. 3 A metal pressure plate—a clip
  • FIG. 4 Tie-plate
  • a solution comprising a reliable and fast fastening of rails on wooden and concrete sleepers includes two basic components.
  • the first is a metal pressure plate ( FIG. 3 ), or a clip, respectively, exerting the required force on the rail base ( FIG. 1 Pos. 1 . 3 ).
  • the metal pressure plate-clip ( FIG. 3 ) has a form of equilateral trapezoid, the longer side of which is bent at a certain radius ( FIG. 3 Pos. 2 . 1 ), allowing a smooth gliding along the tie-plate ( FIG. 1 , Pos. 1 . 4 ) as well as along the rail base ( FIG. 1 , Pos. 1 . 3 ), during pressure.
  • the opposite, shorter side of the metal pressure plate-clip FIG.
  • FIG. 3 is also bent to the same side as the longer one, but in the manner that its edge, resulting from bending is sharp, or making an angle of 90°, respectively ( FIG. 3 , Pos. 3 . 2 ).
  • Such an edge is designed to be within the groove provided on the tie-plate ( FIG. 4 , Pos. 4 . 2 ) in its final, assembled position.
  • the pressure surface ( FIG. 3 , Pos. 3 . 3 ) developed after bending of the shorter side of the metal pressure plate-clip ( FIG. 3 , Pos. 3 . 1 ) serves as the spot to be exerted a force upon acting vertically on such surface, with a purpose of pressing and pulling on the metal pressure plate-clip the rail base. Additional function of the pressure plate ( FIG. 3 , Pos. 3 . 3 ) is to prevent any shifting of the metal pressure plate-clip after finishing the pulling on or the assemblage, respectively. This is achieved by leaning of the pressure surface ( FIG. 3 , Pos. 3 . 3 ) against the inner edge ( FIG. 4 , Pos. 4 . 3 ) of the groove ( FIG. 4 , Pos. 4 .
  • the metal pressure plate-clip ( FIG. 3 ) contains along its central line an oval opening ( FIG. 3 , Pos. 3 . 5 ) designed for the screw to pass through it ( FIG. 3 , Pos. 3 . 4 ).
  • the metal pressure plate-clip ( FIG. 3 ) is on its curving line bent at an obtuse angle ( FIG. 3 , Pos 3 . 4 ), giving the metal pressure plate-clip a resilient pre-stress to exert the required pressure force upon the rail base ( FIG. 1 , Pos. 1 . 3 ).
  • the second component of the solution is a plastic tie-plate ( FIG. 4 ) containing a round hole ( FIG. 4 . Pos. 4 . 5 ) designed for the sleeper screw to pass through it ( FIG. 1 , Pos. 1 . 6 ).
  • the tie-plate ( FIG. 4 ) contains a groove ( FIG. 4 , Pos. 4 . 2 ) designed for the fixation or locking, respectively of the metal pressure plate ( FIG. 3 ) in its final, assembled condition, in the manner that the lower edge ( FIG. 3 , Pos. 3 . 2 ) of the metal pressure plate-clip ( FIG. 3 ) fits in it.
  • the form and depth of the fixation groove ( FIG. 4 , Pos. 4 . 2 ) allows locking.
  • the form of the fixation groove ( FIG. 4 , Pos. 4 . 2 ) is such as to correspond completely to the lower edge of the metal pressure plate-clip ( FIG. 3 , Pos. 3 . 2 ).
  • the pressure surface ( FIG. 3 , Pos. 3 . 3 ) of the metal pressure plate-clip, and the surface of the fixation delimiter ( FIG. 4 , Pos. 4 . 3 ), leaning against each other, ensures a firm locking in the final, assembled position and prevents any shifting of the pressure plate and possible disengagement of the fixation end ( FIG. 3 , Pos. 3 . 2 ) from the fixation groove ( FIG. 4 , Pos. 4 . 2 ).
  • the tie-plate ( FIG. 4 ) also contains a bigger groove ( FIG. 4 , Pos. 4 . 4 ), which is designed for plastic deformation of the metal pressure plate-clip, as applied in the pressure plate dismounting process.
  • the tie-plate ( FIG. 4 ) also contains a surface ( FIG. 4 . Pos. 4 . 6 ) on which the edge of the metal pressure plate-clip ( FIG. 3 , Pos. 3 . 4 ) lies in a pre-assembled condition.
  • the height of the surface ( FIG. 4 , Pos. 4 . 6 ) of the tie-plate corresponds to the height of the rail base itself ( FIG. 1 , Pos. 1 . 3 ), being in contact with it, meaning that those two points are at the same level.
  • FIG. 4 , Pos. 4 . 6 The surface ( FIG. 4 , Pos. 4 . 6 ) is followed by the inclined surface of the tie-plate ( FIG. 4 , Pos. 4 . 7 ) at an angle corresponding to the angle ( FIG. 3 , Pos. 3 . 4 ) at which the metal pressure plate-clip is bent.
  • this coloured surface FIG. 2 , Pos. 2 . 2
  • becomes visible giving the sign that the pressure plate is in the final position.
  • the technical solution according to the invention can be applied in all the cases in which the fastening of rails on concrete or wooden sleepers are concerned.
  • This technical solution provides a high degree of automation in the process of fastening the railway rails on and removing them from sleepers.
  • a self-propelled maintenance vehicle or a device mounted on it, which would continually shift pressure plates in their final position, may be used.
  • a solution to the technical problem according to the invention concerned is based on the embodiment of the metal pressure plate-clip ( FIG. 3 ) and plastic tie-plate ( FIG. 4 ) and their use in the assembly in the manner such as follows.
  • the assembly which is in a pre-assembled condition, and is shown in FIG. 1 , consists of a railway sleeper ( FIG. 1 , Pos. 1 . 1 ) and a tie-plate ( FIG. 1 , Pos. 1 . 4 , and FIG. 4 ), placed on the sleeper, while a metal pressure plate-clip ( FIG. 1 , Pos. 1 . 5 and FIG. 3 ) is placed on the tie-plate in the way that its wider side ( FIG. 1 and FIG. 3 , Pos. 2 . 1 ) is leaned against the surface of the tie-plate ( FIG. 1 and FIG. 4 , Pos. 4 . 6 ) while the rest of the metal pressure plate-clip is placed on the upper surface of the tie-plate ( FIG.
  • the tie-plate ( FIG. 1 , Pos. 4 . 6 and FIG. 4 ) has at its lower part, which is opposite to the groove—a space designed for deformation of the metal pressure plate ( FIG. 4 , Pos. 4 . 5 ), a corresponding protrusion ( FIG. 4 , Pos. 4 . 8 ) made in the same direction as the groove, the surface of which is carried out in such a the way as to lean against a similar groove carried out on the sleeper (Pos. 4 . 8 , FIG. 1 and FIG. 2 ), meaning that they have the same leaning surface (Pos. 4 . 8 , FIG. 1 and FIG. 2 ) and prevent any shifts between the tie-plate (Pos. 1 . 4 , FIG. 1 and FIG. 2 ) and the sleeper (Pos. 4 . 8 , FIG. 1 and FIG. 2 ).
  • the assembly as formed which consists of the tie-plate ( FIG. 1 , Pos. 1 . 4 ) and the metal pressure plate-clip ( FIG. 1 , Pos. 1 . 5 ) is fastened on a sleeper ( FIG. 3 , Pos. 1 . 1 ) by screwing a sleeper screw ( FIG. 1 , Pos. 1 . 6 ) in the railway sleeper ( FIG. 1 , Pos. 1 . 1 ), which screw passes through the oval opening ( FIG. 3 , Pos. 3 . 5 ) made on the metal pressure plate-clip ( FIG. 3 ), and continues through the round hole made on the tie-plate ( FIG. 4 , Pos. 4 . 4 ).
  • the sleeper screw ( FIG. 1 , Pos. 1 . 6 ) by screwing it in the sleeper in the described manner may be fastened even in the factory, using a force, which is pre-determined and sufficient to make the assembly to be firm in its final, assembled condition ( FIG. 2 ), and to make the metal pressure plate-clip ( FIG. 1 , Pos- 1 . 5 ) to exert the force which is required to press the rail base ( FIG. 1 , Pos. 1 . 3 ) against the sleeper, keeping the rail ( FIG. 2 , Pos. 1 . 2 ) in the required position. In such a position, the pressure plate ( FIG. 3 , Pos. 1 . 5 ) covers the vividly coloured upper surface of the tie-plate ( FIG. 2 , Pos. 1 . 4 ), making it invisible.
  • the assembly as finished is ready to be transported to the location where rails would be fastened on sleepers.
  • the final fastening of the rail on sleepers may start by shifting the metal pressure plate-clip ( FIG. 1 , Pos. 1 . 5 ) along the tie-plate ( FIG. 1 , Pos. 1 . 4 ) by the action of Fa force ( FIG. 1 , Pos. Fa) perpendicularly to the surface of the pressure plate ( FIG. 3 , Pos. 3 . 3 ), which is, at the same time, perpendicularly to the rail.
  • Free movement of the metal pressure plate-clip ( FIG. 1 , Pos. 1 . 5 ) in the Fa force direction ( FIG. 1 , Pos. Fa) is enabled by the oval opening ( FIG. 3 , Pos. 3 . 5 ), the dimensions of which are sufficient enough to enable free passage of the sleeper screw body ( FIG. 1 , Pos. 1 . 6 ), but not sufficient to enable the passage of the screw head.
  • Fa force FIG. 1 , Pos. Fa
  • the metal pressure plate-clip is shifted towards the rail base ( FIG. 1 , Pos. 1 . 3 ), until its upper sharp fixation edge, at its opposite side ( FIG. 3 , Pos. 3 .

  • the form of the fixation edge made on the metal pressure plate-clip ( FIG. 3 , Pos. 3 . 2 ) and the depth of the groove made on the tie-plate ( FIG. 4 , Pos. 4 . 2 ) are completely leaning against each other, not allowing thereby the pressure plate-clip ( FIG. 3 , Pos. 3 . 3 ) to return to the previous position.
  • the Fb force ( FIG. 2 , Pos. Fb), by which the metal pressure plate-clip, in its assembled condition ( FIG. 2 , Pos. 1 . 5 ), acts using its edge ( FIG. 2 , Pos. 2 . 1 ) on the rail base ( FIG. 2 , Pos. 1 . 3 ) is in fact the force created by the sleeper screw ( FIG. 2 , Pos. 1 . 6 ), as screwed in the sleeper ( FIG. 2 , Pos. 1 . 1 ), by the fastening force used on the metal pressure plate-clip ( FIG. 1 , Pos. 1 . 5 ), made of spring sheet metal with resilient characteristics, and in the manner that it is, in a non-assembled condition, previously bent according to a curving line ( FIG. 3 , Pos. 3 . 4 ) at a corresponding angle in the direction of Fb force activity.
  • the process of fixation of a rail on a sleeper ends by putting the metal pressure plate-clip ( FIG. 2 , Pos. 1 . 5 ) in the final position in which its lower sharp fixation edge ( FIG. 3 , Pos. 3 . 2 ) enters the fixation groove, made on the tie-plate ( FIG. 4 , Pos. 4 . 2 ).

  • a rail assembled in such a way is ready for traffic and no work performed manually, comprising the fastening of rails on sleepers at that location, is required.
  • Removal of a rail ( FIG. 2 , Pos. 1 . 2 ) from a sleeper ( FIG. 2 , Pos. 1 . 1 ) is achieved by the Fc force ( FIG. 2 , Pos. Fc), which acts perpendicularly to the surface of the metal pressure plate-clip ( FIG. 2 , Pos. 1 . 5 ), achieving its bending deformation, to fill the groove—space for deformation of the metal pressure plate-clip ( FIG. 4 , Pos. 4 . 4 ).
  • the technical solution comprising the fastening of rails on sleepers by resilient clips according to the invention includes the use of the corresponding device, which can be mounted on the maintenance vehicle, and the whole process of fastening the rails on sleepers as well as removing them from the sleepers may be carried out fast with a high degree of automation, reduced costs, reduced number of workers, and reduced time to be spent on mounting and dismounting activities.
