Definitions

  • the invention relates to a device for mounting a tongue rail of a switch, according to the preamble of claim 1.
  • Tongue lifting devices as in DE 198 12 795 C1 described, reduce wear and thus save large amounts of lubricant by pressing the tongue rail upwards by a spring and only resting on the sliding chair when a train passes over it.
  • a disadvantage is the still considerable actuating force, since the frictional force is largely independent of the area.
  • connection to the threshold or the switch base plate requires precise adjustment at at least two points.
  • EP 2 995 718 A1 discloses a device for mounting a tongue rail of a switch, comprising a rolling element and a cantilevered leaf spring which can be pretensioned to the tongue rail and on which the tongue rail is arranged so as to be displaceable by means of the rolling element.
  • the leaf spring is arranged in a guide body, which can be fastened to a stock rail of the switch.
  • the tongue rail is stored in several places.
  • the tongue stroke and the distance to the stock rail are different for the different bearings.
  • the tongue stroke is small near the tongue root and the distance to the stock rail is large.
  • the tongue stroke is large and the distance in the adjacent position is zero.
  • the object of the present invention is to expand the function of conventional bearings and to offer a much simpler, and therefore also quick-to-assemble and inexpensive device for storing tongue rails.
  • this object is achieved by a device having the features of claim 1.
  • tongue storage can be considerably simplified.
  • the required actuating force is significantly lower than with conventional storage of switch tongues or tongue rails. This significantly reduces the switching force.
  • the forces to be exerted by the drives are significantly lower, which protects them.
  • the actuator could be made significantly smaller.
  • the adjustability of the position of the leaf spring bearing in the guide body via a slide proves to be particularly advantageous, as a result of which the device can be used universally and production and storage are greatly simplified. This enables the position of the rolling element to be adjusted in a simple manner and be adapted to the circumstances with high accuracy. Regardless of the position of the slide in the guide body and thus the position of the Rolling body compared to the stock rail, the spring length, and thus the mechanical or elastic properties remain constant.
  • the slide can be fixed in the guide body both positively and frictionally, the frictional variant comprising splines, for example. This has the advantage of a stepless adjustment.
  • the slide can be fastened to the guide body via a connection which consists of a surface of greater hardness with a regular or irregular surface structure and a counter surface of lower hardness.
  • the harder surface can be made of steel, for example, and the counter surface can be made of brass or aluminum, for example. Security against loosening is achieved by embossing the surface structure of the harder surface into the softer counter surface when the screw is tightened.
  • teeth can be provided both on the slide and in the guide body, as a result of which the position of the slide is permanently fixed in the direction of adjustment, which is preferably fastened by screwing. An adjustment of the cantilever over the life of the device by vibration, for example, is thus prevented. It proves to be particularly favorable if the toothing is arranged on one side of the guide body or the matching counterpart on one side of the slide. A secure connection can be achieved if the screw connection is arranged on the same side as the toothing.
  • the position of the guide body relative to the stock rail can also be changed.
  • the clamping body which represents the connection to the stock rail, and on the guide body, with which the clamping body and guide body can be screwed together in different positions. This enables a rough adjustment, the fine adjustment can be carried out by moving the slide in the guide body.
  • Another possible embodiment variant provides that the clamps are arranged directly on the guide body in order to obtain a simpler system from fewer individual parts.
  • the contact force between the tongue rail and sliding chair can be reduced as desired.
  • the tongue When the tongue is rolled up, it can be lifted entirely from the sliding chair, which completely eliminates the contact force when sliding over it.
  • the preload can be adjusted via the height of the rolling element in relation to the roller block.
  • a height adjustment of the rolling element in a roller block, which forms the connection between the rolling element and the leaf spring, can therefore be particularly advantageous for precise adjustment.
  • the use of screws for adjustment proves to be advantageous.
  • roller block is attached to the leaf spring by means of a dowel with a rotational degree of freedom that allows the roller block with rolling element to pivot slightly about a vertical axis.
  • Attachment to the base of the stock rail enables storage that is independent of different sleepers or sliding chair geometries. This can be achieved particularly cheaply by a clamp connection.
  • a rigid clamp which is preferably formed in one piece by the clamp body, and a screw clamp, which can be screwed to the clamp body, are particularly suitable for this purpose.
  • a universal use can be achieved by several receptacles in a row for the screw terminal and a corresponding toothing. During installation, the distance between the clamps can thus be adapted to the existing rail system, in particular the width of the base of the stock rail.
  • a guide body 1 is fastened to a stock rail 3 via a clamp body 15 of a device according to the invention by means of clamps 2a, 2b.
  • the guide body 1 is box-shaped in a U-shape and firmly connected to terminals 2a, 2b by means of a clamping body, a rigid terminal 2a and a screw terminal 2b being present.
  • the rigid clamp 2a is arranged on the clamp body 15, to which a screw clamp 2b is screwed.
  • the guide body 1 is screwed to the clamping body 15.
  • a carriage 4 which in turn can be displaced and fastened in the longitudinal direction within the guide body 1.
  • elongated holes 12 on a side wall of the guide body 1 for fixing the slide 4 with a screw 13.
  • a rack 5 is provided on the inner wall of the guide body 1.
  • Rack pieces 6 engaging in the rack 5 are arranged on the side of the slide 4.
  • the relative position of the clamping body 15 to the slide 4 can thus be roughly defined by means of the connection between the clamping body 15 and the guide body 1, a fine adjustment is possible via the connection between the guide body 1 and the slide 4.
  • Both the distance between the stock rail 3 and a tongue rail 11 and the tongue stroke of the tongue rail 11 differ according to the position of the storage within the switch. In the vicinity of the tongue root, the range of movement of the tongue rail 11 is small and the distance to the stock rail 3 is large.
  • Such a structure is in the 3a and b , such as 4a and b to see.
  • 3a and b show the tongue rail 11 in a position adjacent to the stock rail 3.
  • 4a and b show the tongue rail 11 in a position remote from the stock rail 3.
  • the distance between the middle of the stock rail and the edge of the tongue (contact with the roller) differs depending on the type of turnout.
  • FIGS Fig. 1a, b A device according to the invention in a region closer to the tip of the tongue is shown in FIGS Fig. 1a, b in the position of the stock rail 3 and 2a, b shown in the position remote from the stock rail 3.
  • a leaf spring 8 is attached to the slide 4.
  • the surface of the guide body facing away from the stock rail 3 is held at a distance A by the slide 4. This is dimensioned such that the leaf spring 8 does not rest on the guide body 1 even at maximum load. As a result, the effective length of the leaf spring 8 and thus the spring properties remain constant.
  • Another end of the leaf spring 8 is connected to a roller body 10 via a roller block 9 and set screws 17.
  • the base of the tongue rail 11 lies on this.
  • the roller block 9 is connected to the leaf spring 8 by a vertical dowel pin 16. This allows a slight rotation about its axis, as a result of which the tolerances of the rolling elements 10 align at the correct angle to the contact surface of the tongue rail 11.
  • set screws 17 are also arranged in the roller block, with which the rolling element 10 is adjustable in height.
  • the pretensioning of the tongue rail 11 can be adapted to the requirements.
  • the roughly required rolling element position is initially set via the clamping body 15 - guide body 1 connection. This can be done at the factory in the form of product variants consisting of the same parts, or at the construction site at the start of assembly.
  • the entire device is clamped to the stock rail 3 via the clamps 2a, 2b.
  • the slide 4 is fine-adjusted in the guide body 1, and thus also the position of the roller body 10 relative to the stock rail 3.
  • the position of the slide 4 is fixed with the screw 13, through the rack 5 and the rack pieces 6 an adjustment, for example by vibration , leaning forward.
  • the entire system is biased against the tongue rail 11.
  • Fig. 10 shows an alternative embodiment with two roles. This can be used, for example, when the tongue stroke is greater than the width of the foot of the tongue rail plus the roll-up path.
