Definitions

  • the invention relates to a device for securing the position of the tongue rails of track switches, in which an arm of an angle lever is articulated to each tongue rail, the other arm of which is supported against an energy accumulator, in particular formed by a compression spring, each angle lever at the point of intersection thereof Arms is mounted on a fixed pivot axis and the line of action of the force of the energy accumulator is in the two end positions of the angle lever on different sides of the pivot axis of the angle lever.
  • an energy accumulator in particular formed by a compression spring
  • the line of action of the force of the energy accumulator includes a relatively small angle in the end positions of the angle lever with the associated arm thereof, against which the energy accumulator is supported.
  • the force component which acts on the arm in question transversely to it and presses the angle lever into its end position, is therefore relatively small and the angle lever is not held in its end position with the necessary certainty by this force component.
  • the object of the invention is to increase the safety with which each angle lever is held in its end position by the energy accumulator in the device described at the outset.
  • the invention essentially consists in the fact that a single energy store is supported against the arms of the two angle levers and is articulated directly on these arms.
  • both angle levers swivel in different directions. Since the energy accumulator supported on the arm of one angle lever is not stationary but is supported against the arm of the other angle lever, the support points of the energy accumulator shift opposite.
  • the angles which include the direction of force of the energy accumulator with the arms of the two angle levers acting on the energy accumulator in the end positions thereof are increased.
  • the force components acting transversely to these arms are thus increased and the two angle levers are therefore held in their end positions with greater certainty. This increased security is of paramount importance.
  • the angle levers can be articulated to the switch tongues by means of length-adjustable rods.
  • This enables the position of the tongue rail in the end positions of the angle levers to be set precisely.
  • the end position of each angle lever which determines the distance of the tongue rail can be determined by a fixed, optionally adjustable, stop.
  • the position of the tongue rail is determined by these fixed stops and if these fixed stops are adjustable, the position of the tongue rail can also be adjusted or corrected accordingly by these stops, in which case the length adjustment of the rods by means of which the angle levers are articulated to the switch tongues are not absolutely necessary.
  • the device is arranged in turnouts with a large radius in at least an intermediate region of the length of the turnout.
  • the correct position of the tongue rails in the central area of the turnout cannot be guaranteed due to the length and elasticity of the turnout tongues, and in this case the device can support the tongue rails in the intermediate area of the turnout.
  • an insufficient clearance between the tongue rails and stock rails could hinder the free passage of the wheel rims of the wheels, which could result in damage to the wheel rims.
  • the arrangement can also be such that the two tongue rails are connected to one another by a connecting rod which is articulated and preferably adjustable in length and on which the free arms of the angle lever and the switch device engage.
  • a connecting rod which is articulated and preferably adjustable in length and on which the free arms of the angle lever and the switch device engage.
  • Such an arrangement can be used as an adjustment device instead of the usual clamp lock, in particular in the case of low-stress switches, such as switches for industrial tracks or underfloor and grooved rail switches. This is where the greater safety comes into play, which is achieved in that the arms of the angle levers are supported against one another by a single energy accumulator and the force with which the angle levers are held in their end positions is increased.
  • 1 shows a device arranged in the central region of a switch.
  • 2 shows a device which is arranged in the tip area of the switch tongues and which at the same time serves to switch the switch.
  • 1 shows a plan view of the central area of a switch.
  • 1 and 2 are the stock rails
  • 3 and 4 are the tongue rails.
  • a plate 5 is fixed to the sleepers.
  • This plate carries pivot axes 6, on which angle levers 7 and 8 are pivotally attached.
  • the ends of the arms 9 and 10 are articulated on the tongue rails via length-adjustable rods 11.
  • the arms 12 and 13 are supported against one another by an energy accumulator 14 formed by a compression spring.
  • the tongue rail 4 lies away from the stock rail 2, the passage between the stock rail 2 and the tongue rail 4 being designated by 15.
  • the tongue tip (not shown) of the tongue rail 3 lies on the stock rail 1 at.
  • the end position of the angle lever 8, which determines the largest passage 15 between the stock rail 2 and the tongue rail 4, is determined by a stop 16.
  • the end position of the angle lever 7 is determined in an analogous manner by a stop 17.
  • the axes 6 and the stops 16 and 17 are fixed in place on the plate 5.
  • the angle lever 7 and 8 in cooperation with the Energy store 14 also limits the narrowest passage 15 between stock rail 2 and tongue rail 4 and it is important to ensure this narrowest passage so that the wheel flanges of the edges can pass over stock rails 1 and 2 without hindrance.
  • the ends or articulation points 18 and 19 of the arms 12 and 13 move in opposite directions.
  • the angle ⁇ which includes the line of action 20 of the force of the energy accumulator 14 with the arms 12 and 13, is considerably larger than when the energy accumulator 14 would be supported in a stationary manner, and the end position of the angle levers 7 and 8, which determines the passage 15 between the stock rail and the tongue rail, is maintained with greater certainty.
  • 21 is a telescopic tube which prevents the compression spring 14 forming the energy accumulator from buckling.
  • the device is arranged in the area of the tongue tips and at the same time serves as a switching device for the switch.
  • a length-adjustable connecting rod 24 is articulated on the tongue rails 3 and 4.
  • the lever arms 9 and 10 are articulated on this connecting rod 24 at 25 and 26 and on the connecting rod 24 an adjusting rod 28 engages at 27, which serves to adjust the switch.
  • the positions of the tongue rails are secured again by the angle levers 9 and 10. However, since the two tongue rails are connected by the connecting rod 24, the stops 16 and 17 according to FIG. 1 are unnecessary.
  • the end positions of the angle levers 9 and 10 are determined in that one of the tongue tips 22 or 23 bears against the respective stock rail 1 or 2.
  • An embodiment according to FIG. 2 can be used with points that are not subject to high loads, such as, for example, industrial iron switches, underfloor switches or grooved rail switches.
