Definitions

  • the invention relates to a heart piece with a heart tip and wing splints which are connected to the heart tip, in which the wing splints are welded to the heart tip using lining pieces.
  • heart tips with cast-on or welded-on lining pieces are also known for the production of heart pieces, the wing rails being screwed onto the heart tip by means of the lining pieces.
  • the chucks serve to keep the distance and the high-strength screw connection is exposed to various loads in use, which make frequent maintenance and inspection necessary.
  • the forces that occur in the track, which is laid without gaps, result in a relative movement between the apex of the heart and the wing rails, which on the one hand loosens the screw connection and on the other hand introduces additional shear forces and tensile forces into the screw connection.
  • block frogs are often used in which the frog tip is formed in one piece with the wing rails.
  • the vibrations occurring in the track are introduced into the entire block frog consisting of the frog tip and wing rails there are a number of disturbing factors in the vibration behavior compared to the rest of the track.
  • the centerpiece according to the invention essentially consists in the fact that the lining pieces have a lower height in the welding position than the web of the wing rails.
  • Such chucks allow the elasticity of the wing splints in the vertical direction while ensuring the desired elasticity of the welded joint and ensure that the vibrations of the track are only transmitted to the part directly connected to these rails and thus to the wing splints or the apex of the heart, the rigid Coupling between the apex of the heart and wing splints is released. Since the screw connections are omitted, the maintenance effort is significantly reduced.
  • the fact that lining pieces are used avoids the disadvantages of center block centerpieces or monoblock centerpieces, in which a continuous groove generally remains between the wing rail and the centerpiece, which can result in malfunctions in operation. Furthermore, with such monoblock or middle block heart pieces, subsequent bending of the heart piece for curved switches is generally difficult.
  • the elastic construction according to the invention using welded lining pieces such adjustments to the heart of the turnout.
  • the design according to the invention is such that the lining pieces are formed by plate-shaped elements, the main plane of which extends in the longitudinal direction of the rail.
  • Such plate-shaped elements as lining pieces with the main plane running in the longitudinal direction of the rails are capable of absorbing the relative movements between the apex of the heart and the wing rail without this leading to excessive stress on the weld seams.
  • the height of the plate-shaped elements can advantageously be less than the width of the elements between the tip of the heart and the wing splint in order to allow relative movements between the heart tip and the wing splint.
  • Particularly favorable vibration-damping properties can be achieved if the length of the lining pieces corresponds to half to three times the width of the lining pieces.
  • the width of the chuck is dependent on the rail profile.
  • the height of the pieces of lining can advantageously correspond to one to two thirds of the width, preferably approximately half of the width, which enables the oscillation of the wing splints to be largely decoupled from vibrations of the tip of the heart introduced via the heart connecting splints.
  • Such dimensioning which is only to be taken into account in the case of chucks between the frog tip and wing splints, has, in addition to the advantageous vibration properties, the advantage that the susceptibility to faults can be further reduced by spacing the chucks in the longitudinal direction of the wing splints or the heart tip are arranged, which corresponds to three to five times the length of the feed pieces. A continuous groove between the tip of the heart and the wing splints is thus avoided, so that there is also a groove in this groove Accumulation of material that could give rise to faults cannot occur.
  • a particularly stable design can be achieved in that the wing splints near the apex are also welded to one another with at least one lining piece, the relative movement between the wing splints and the apex being in no way impaired by such a direct welding of the wing splints using a lining piece.
  • the wing rails can be further fixed to the heart connection rails in a conventional manner by means of screwed chuck pieces, the remaining stress on the screw connection in the screw axis being low by moving the wheels at the rear wing rail inlet and no maintenance effort being required when using a screw lock.
  • FIG. 1 shows a plan view of a centerpiece according to the invention
  • FIG. 2 shows a section along the line II-II of FIG. 1
  • FIG. 3 shows a section along the line III-III of FIG. 1.
  • a heart tip 1 is shown, with which heart connecting rails 2 and 3 are connected.
  • Wing rails 4 and 5 are provided to the side of the cardiac tip 1 and are welded to the cardiac tip 1 via chucks 6.
  • Wing rail connection rails or control rails 7 and 8 are connected to the wing rails 4 and 5.
  • the wing rails 4 and 5 are screwed to the heart connection rails 2 and 3 by means of chucks 9.
  • one or more chucks 10 are welded in front of the frog tip between the wing rails.
  • the selected lining pieces 6, which are respectively welded to the wing rails 4 and 5, have a height a which is significantly less than the height b of the web of the wing rails 4.
  • the lining pieces 6 are formed by plate-shaped elements, the main plane of which extends in the longitudinal direction of the wing rails 4 or the connecting rails. The length in this longitudinal direction c is significantly greater than the height a of the plate-shaped elements which are used as lining pieces 6.
  • the heart tip 1 is formed as a composite material in the embodiment according to FIG. 3 and carries a highly wear-resistant material at the wheel overflow point.
  • the tip of the heart can be made of composite material or cast manganese steel. It is also possible to design the wing rails from composite material or from rolled manganese steel.
  • connection between wing rail and cardiac tip is made by welding in the spacers 6, depending on the choice of material for the cardiac tip and the wing rails, a material must be selected that ensures the perfect welding of these materials in the combinations mentioned as a material for the execution of the center piece can be selected a composite workpiece, the wheel tread of a hardenable steel with the composition C 0.01 to 0.05% Si 0.01 to 0.2% Mn 0.01 to 0.2% Co 0 to 15% Mo 1.5 to 6% Ni 7 to 20% Ti 0.1 to 1% Cr 0 to 13% Al 0 to 0.2% B 0 to 0.1% Zr 0 to 0.1% is trained.
  • a hardenable steel with the composition C 0.01 to 0.05% Si 0.01 to 0.2% Mn 0.01 to 0.2% Co 0 to 15% Mo 1.5 to 6% Ni 7 to 20% Ti 0.1 to 1% Cr 0 to 13% Al 0 to 0.2% B 0 to 0.1% Zr 0 to 0.1% is trained.
  • Such a steel is easy to weld and easy to machine in the solution-
  • Steel grades of this type are distinguished by the fact that, by aging at 200 ° C. to 600 ° C., they assume a very high hardness with good toughness, which is achieved by martensitic transformation and / or precipitation of intermetallic phases.
  • the wing rails can also consist of a composite material of this type or can be rolled, for example, from high manganese steel.
  • the tip of the heart from cast manganese steel in a known manner, and the wing rails can also be made from manganese steel in order to simplify the welding and the subsequent temperature treatment.
  • a targeted temperature control must be observed in accordance with the selected starting materials, the spacers being positioned with a view to improving the vibration behavior of the overall construction.
