Definitions

  • the invention relates to a device for adjusting and for the elastic locking of the end position of movable Turnout parts, especially turnout tongues of grooved rail turnouts, with an axially movable rod and a die Rod surrounding tube, in which a surrounding the rod Spring is clamped against stops and radially displaceable Locking members are arranged, the Rod at an axial distance control stops for a radially inner Location of the locking members and the pipe stops for the has outer layer of the locking members.
  • a facility is disclosed for example in WO 98/54041.
  • a conversion aid are also from AT-PS 379 624 already known, with a spring rocker used here came at an angle lever at the crossing point of the arms is mounted, an energy accumulator by means of a compression spring is supported against the arms of the two angle levers. Two spring rockers were here over a coupling rod with the two tongue rails connected.
  • a conversion aid is from the Austrian application A 2137/97 for elastic locking of movable switch parts became known, in which locking members in axial distance from each other in between a tube and a Rod-arranged cages are stored, between them Cages arranged a compression spring acting in the axial direction is.
  • the rod is connected to the tongue rails via coupling rods connected, wherein control grooves are arranged on the circumference of the rod which are the locking members in their different Move positions so that the compression spring during the changeover process is tensioned and in the position of the plant on the tongue the grooved rails exert a contact pressure on the tongue.
  • the Ball cages are axially movable to a limited extent, so that it can be used with different tongue flaps or different transverse movement of the tongue is possible.
  • FR-A-2 523 537 is already a changeover aid with a integrated hydraulic drive became known, with spring rockers are in the form of two compression springs, which on Housing of the earth box are supported and after exceeding corresponding dead center positions take effect.
  • EP-A1 0 779 197 a device for securing the end positions hydraulic actuators.
  • the invention now aims to meet the requirements for to create compact short drive and changeover aid, which is particularly due to the use of grooved rails short overall length is suitable and ensures that the resilient Pressing force on the tongue independent of an adjustable one active adjustment path takes effect to constant pressure forces to the tongue regardless of the adjustment stroke can.
  • the compact unit should also give you the opportunity occurrence of lateral forces can be reduced, whereby the wear can be significantly reduced.
  • the training according to the invention essentially in that at least one of the tax attacks adjustable on the rod in the axial direction of the rod is definable. Because at least one of the tax attacks adjustable on the rod in the axial direction of the rod can be determined, the stroke and so that the required adjustment path can be set, whereby by the ability to postpone and determine the tax rate at the same time it is ensured that at the end of each stroke the full and constant spring force is effective.
  • the training can be particularly simple according to the invention Be taken so that the rod is divided is, the axial position of a rod part, which carries a tax stop, opposite the other rod part is changeable.
  • the change in the axial length of the rod part with simultaneous axial displacement of the control stop can in principle be realized in different ways become. If the axial length of a rod part compared to that other rod part is changed, for example done that a rod part with an external thread and second rod part is formed with an internal thread, wherein the rod part with the external thread into the rod part with the Internal thread is screwed in or out.
  • the adjustable control stop as the end face of a sleeve is formed, which can be screwed onto the rod and attached its free end with the coupling rod to the movable rail part connected is.
  • the adjustable tax stop supporting sleeve can be easily on the rod screw on and can also be easily adjusted afterwards.
  • such a facility can also against unintentional adjustment in a particularly simple manner secure and lock in the selected position of the sleeve or block.
  • the sleeve has an internal thread, in which a locking piece carrying an external thread like a Lock nut in the stop on the rod can be screwed.
  • the training is advantageously made such that the drive from one into the tube coaxial to the axis or rod integrated and movable cylinder piston unit whose maximum displacement is greater than the permissible Adjustment range of the control stop or the sleeve.
  • Such Integration of a hydraulic drive in the adjustment and Locking device leads to particularly short dimensions and at the same time to reduce the risk of eccentric eccentric forces which cause wear could increase.
  • Particularly compact dimensions can be achieved if the piston of the cylinder-piston unit is rigid with the Rod is connected, the piston rod with which the control stops carrying rod is ident.
  • a training secured against the ingress of dust can thereby can be achieved that the tube on both sides of end faces is closed, preferably in a manner known per se the locking members are designed as balls and in axial sliding cages are guided radially, the spring arranged between the facing end faces of the cages is.
  • FIG. 1 shows a top view of a schematic Arrangement of the device according to the invention and Fig. 2 a Axial section through a device for elastic locking and adjustment of switch parts with integrated hydraulic Drive.
  • a grooved rail switch can be seen, the movable switch tongues with 1 and the stock rails with 2 are.
  • the switch tongues 1 are via a tongue linkage 3 and universal joints 4 with the device according to the invention for Adjust and for elastic locking of movable Turnout parts 5 connected.
  • the switching device 5 is with the Inspector linkage 6 in a first U-shaped open box 7 stored. Due to the coupled design of the changeover device Installation in an open earth box is possible and therefore one easy accessibility for service measures.
  • the electrohydraulic Drive 8 is sealed in a separate box part 9 firmly attached to the box 7. Both Box parts are provided with a cover plate, whereby at Requirement the entire box construction is isolated from each other the rails is embedded.
  • the changeover device is shown in one position, in the tongue on the left side of the stock rail is applied.
  • the 17 designated outer tube forms the Housing for the changeover device.
  • a rod 15 and a sleeve screwed onto the rod 15 16 arranged, which at its free ends with the in Fig. 1st shown universal joints are connected.
  • two cylinder blocks 19 are arranged, which form a cylinder space Limit 20 and this to the outside or to the drawing Seal the left part of the device sealingly.
  • On the Rod 15 is a cylinder piston in the area of the cylinder space 20 21 screwed on, which with the pressure of a hydraulic fluid can be acted upon in the outer tube 17 provided connections 18 and those shown in Fig.
  • the rod 15 has an in its circumference Cross-section of trapezoidal groove 22 and has a section 23 with a smaller diameter, which section 23 together with the End face 25 of the sleeve 16 screwed onto the rod 15 forms a second groove, which is also trapezoidal in cross section is.
  • the end face 25 of the sleeve 16 forms at the same time a control stop for the radially inner position of a first Locking member formed by balls 26 and in one axially displaceable cage 27 is guided radially.
  • the stop 24 of the groove 22 is effective.
  • the cages 27 and 27 'each have a support ring 28 and 28', respectively which is a compression spring acting between the cages 27 and 27 ' 29 supports.
  • In the fixed outer tube 17 are pieces of pipe 30 and 31 inserted, which stops 32 and 33 for have the radially outer position of the locking members.
  • the Pipe piece 30 is supported on the cylinder block 19 and that Pipe piece 31 on the outer cover 34, with a locking ring 35 is fixed in its axial position.
  • the first Spring 29 compresses until the locking members 26 themselves shift radially outward into the stop 33.
  • the further shift the rod 15 in the direction of arrow 36 is as long free from any spring force until the locking members 26 'enter radially inward into the groove 22 of the rod and cooperate with the stop 24 such that the further displacement now by relaxing the compression spring 29 is supported and that when the right end position is reached the spring contact of the right tongue under the action of the compression spring 29 is guaranteed.
  • the hydraulic system of the cylinder-piston unit is in circulation switched and therefore does not exert any force on the drive piston 21 out.
  • the spring 29 slightly compressed and in the respective end position relaxed again to length L. It can therefore be a very short one Compression spring should be chosen, because only a small spring travel during of the changeover process is required. It is therefore a linear one Cylinder / spring rocker arrangement provided by the tubular design can be easily encapsulated and sealed to the outside.
  • the unit is adjustable for a stroke of approximately 35 to 60 mm and ensures an end position holding force via the compression spring from approx. 2600 to 2800 N. Because the hydraulics of the Cylinder-piston unit in the end positions each in circulation is switched, the device also enables a forced changeover with the wheel flanges (opening the switch).
  • the slicing force of the changeover mechanism is approximately 4000 N. according to the maximum preload force of the end position holding mechanism and the displacement resistance of the compression spring of the Spring toy mechanism. Overloads or damage to the Actuating mechanisms cannot occur here.
