Definitions

  • the invention relates to a device for end position testing of moving parts of a rail switch, wherein each movable switch part is assigned at least one separate Endlagenprüf healthy, the Endlagenprüf shark comprises a rod and a scholarergeophuse, in which the rod is inserted and in which at least one limit switch for detecting the both end positions of the movable switch part is arranged.
  • Adjustments for movable switch parts such as in particular tongue rails or movable frogs, which are provided with a Endlangprüf noise are known as belonging to the prior art generally.
  • the mechanical changeover of the movable switch part is effected by means of an electric or hydraulic point drive, wherein in addition to the points drive a separate or integrated in this closure device and in any case a separate Endlagenprüf sexual is provided.
  • Such Endlagenprüf sexualen serve to mechanically scan the current state of the switch soft and produce a test signal, can be reliably determined by means of whether the switch has been correctly changed and whether the adjacent and the outlying tongue are in their respective correct end position.
  • the Endlagenprüf has a scholarergestlinde, which extends substantially transversely to the rail longitudinal direction and which is displaced when changing the switch in the longitudinal direction of the linkage.
  • the positions of the tester bars are detected by means of electromechanical transducers, for example in the form of limit switches or tongue test contacts, which are arranged in a housing, which is usually mounted laterally of the switch on a threshold.
  • the end position tester has also been integrated into a common housing with the adjustment drive.
  • Another version is from the DE 29917829 U1 become known, in which a continuous Anlagenric acid is provided, the two rod parts are guided telescopically under interposition of a spring element.
  • the limit switches are designed as rigidly connected to the für tange shift finger, which interact with proximity switches.
  • solutions are known in which grooves are formed on the für tange, which can engage in the shift lever and trigger the limit switch in this way.
  • this will be the US 5,669,587 and the WO2004 / 014710 A1 cited.
  • the present invention aims to provide a Endlagenprüf adopted, in which a simple way to adapt to the different displacement paths of the movable switch parts is possible without complicated conversion work is required, and in particular without an opening of the excergeophuses is necessary.
  • the adaptation to the different displacement paths should also in the installed state of Endlagenprüf boots be possible to make, for example, a subsequent adaptation to the resulting wear and tear during operation changes the Umstellhubes.
  • the device according to the invention is substantially designed such that the rod has in its immersed in the housing portion or the housing at least two axially spaced apart switching edges for the actuation of the at least one limit switch, wherein at least one of the switching edges relative to the other switching edge is adjustable in the axial direction and is arranged fixable in the respective position.
  • each tongue rail is assigned a separate Endlagenprüf coupled, so that the adaptation to different adjustment paths for each tongue rail can be made separately.
  • the possibility of the exact setting of the test device means that even slight deviations from the end position cause the limit switch is not actuated, so that a corresponding malfunction at the control point is immediately apparent.
  • a reliable functioning of Endlagenprüf consensus is only guaranteed if proper guidance of the für eachmandange is given in the housing.
  • the Endlagenprüf resonance is usually exposed to mechanical stress, for example, by the influence of vibrations, which are transmitted from the tongue rail on the tester, by thermal stresses or bending or torsional moments.
  • the housing is designed as a tube with a circular cross section, in which the rod dips sealingly. Due to the circular cross-section of the housing, the functionality of the end position tester is not impaired even in the event of torsional stress or torsion of the tester linkage, and in particular of the tester rod, with the seal termination of the tester housing in the area in which the tester rod dips into the tester housing. is preserved in any case by the circular design. In addition, such a design ensures a particularly compact design, so that the limited space in the area of the switch tongue can be taken into account optimally.
  • the rod-shaped component is designed as a tester rod which is coupled to the movable soft part and which is immersed in a stationary or stationary housing, the limit switches being rigidly connected to the stationary housing.
  • the rod is connected to a fixed part of the switch and the tube is coupled to the movable part, which is particularly advantageous if, as it corresponds to a further preferred embodiment , the at least one Limit switch is connected to the rod and can be actuated by the arranged on the inner surface of the tube switching edges. As a result, a particularly compact design is achieved.
  • the switching edges for the actuation of the limit switches are thus arranged in this embodiment on the movable housing and cooperate with limit switches, which are arranged on the rod connected to a stationary part of the switches.
  • the axial adjustment of the switching flanks provided in the tube for adjusting the distance between the two switching flanks and thus substantially easier to adapt to the respective Umstellhub wherein it is preferably provided that on the inner surface of the tube defined by the switching edges switching grooves are formed.
  • the limit switches can engage upon reaching the respective end position, wherein for adjusting the distance between the switching grooves is preferably provided that at least one of the switching edges is formed on a relative to the pipe in the axial direction adjustable component.
  • the adjustable component can in this case be designed as screwed into the tube inner tube, so that by rotation of the inner tube relative to the housing tube, the switching edge can be adjusted in the axial direction.
  • the at least one limit switch comprises a spring-loaded plunger or cooperates with a spring-loaded actuator, which (s) when correctly adjusted the movable switch member engages in the switching groove defined by the switching edge.
  • the spring-loaded ram or the spring-loaded actuator ensures that the plunger or the actuator acts against the enclosing pipe, so that always a compulsive actuation of the changeover switch takes place when the tongue rail has not yet reached the required end position. Only when reaching the end position engages the spring-loaded plunger or the spring-loaded actuator in the corresponding shift groove, which is arranged on the inner circumference of the enveloping tube.
  • at least two limit switches are preferably provided, wherein each limit switch can be actuated by an associated switching edge. With appropriate interconnection of the two limit switches this case a reliable control of the correct intake of the respective end algae can be achieved.
  • the coupling of Endlagenprüf recognized to the movable switch part is preferably carried out in that the tube or the inner tube has a connection point for a connector for coupling to the movable switch part.
  • the tube in Rail longitudinal direction slidably connected to the movable switch part.
  • the tube to the movable switch part about an axis parallel to the rail longitudinal axis is pivotally connected.
  • the pivotal mounting can be made using elastic links and / or spherical bearings, so that vibrations of the tongue rails are compensated and not forwarded to the test device. An actuation of the limit switches exclusively due to such vibrations is thus excluded, so that the reliability of the tester can be increased.
  • the tilting moments and the like acting on the movable switch parts during the passage of the switch are likewise taken up by the pivotability of the test device in the joint or in the elastic connecting link.
  • the training is advantageously developed such that the rod is connected to a sliding block, which is displaceable in the axial direction relative to a stationary bearing block.
  • the entire Endlagenprüf can be adjusted in a direction transverse to the rail longitudinal direction, so that an improved adaptation to the different Umstellhübe succeed.
  • it is thereby possible to arrange one and the same Endlagenprüf recognized at different points along the switch, which can be adjusted by the axial displacement of the Endlagenprüf drove the effective length of the strigergestlindes.
  • the displaceability can be made possible in a simple manner in that the fixed bearing block carries a transverse to the rail longitudinal direction spindle, which cooperates with an internal thread of the sliding block. By rotation of the spindle thus takes place a corresponding stepless axial displacement of educable words.
  • Fig.1 a section of a rail switch with stock rails 1 and 2 and tongue rails 3 and 4 is shown.
  • the tongue rail 3 is in this case in contact with the stock rail 1
  • the tongue rail 4 is in storage from the stock rail 2.
  • the tongue rails 3 and 4 are each assigned separate Endlagenprüf recognizeden 5 and 6, so that a complete mechanical Endkoppelung the tongue rails 3 and 4 achieved becomes.
  • the Endlagenprüf sexualen 5 and 6 are each defined via bearing blocks 7 at a threshold 15.
  • the Endlagenprüf sexualen each consist of a rod 8, which dips into a tubular housing 9 sealingly, wherein the tube 9 is coupled via an articulated clevis 10 to the tongue rail 3 and 4 respectively.
  • FIG 3 the manner of coupling the Endlagenprüf driven is shown in more detail to the movable tongue rail.
  • a hinged clevis 10 is provided, which carries a bolt 18, so that the tube 9 is pivotally coupled about an axis 19 to the tongue rail.
  • the fork head 10 surrounds the foot of the tongue rail and is fixed with a screw to the rail web.
  • a retaining plate 20 in this case fixes the position of Endlagenprüf driven in the rail longitudinal direction in which the retaining plate 20 is laterally supported on the sliding chair 38. This design prevents that a longitudinal extension of the rail transmits to the tester.
  • the holding plate 20 further has a not-visible in the figure vertically aligned slot, whereby the clevis 10 is relieved of vertical forces.
  • the rod 8 which is rigidly connected to the end piece 16, carries at its end immersed in the tube two limit switches 21 and 22.
  • the actuating mechanism for the limit switches consists of two symmetrically arranged to the central axis switch tappets 23 which are resiliently biased against each other and to the outside pressed against the inner shell 24 of the tube 9.
  • the switching plunger 23 cooperate with a switching cone 25 which acts directly on the actuating plunger 26 of the limit switch.
  • the limit switch is in this case actuated as long as the switch plunger 23 are in the radially inwardly held position, as in the situation shown in the figure for the limit switch 21 applies.
  • the switching plunger 27 are shown in the radially outwardly displaced position and engage in: a shift groove 28, whereby the limit switch 22 is no longer actuated.
  • a further shift groove 29 is provided in addition to the shift groove 28, in which the switch plunger 23 of the limit switch 21 can engage with a corresponding change of the switch.
  • Fig. 7 It can be seen that the sealing bearing of the rod 8 in the tube 9 is achieved by a capping member 34 which is screwed onto the end of the tube 9 facing the rod and carries corresponding seals 35 for the sealing guidance of the rod 8.
  • the rod 8 is further connected to a support member 36 to which the limit switches 21 and 22 are fixed.
  • a modified embodiment is shown, in which with the carrier-like member 36 a total of four limit switches are connected.
  • two switches are provided for each end position, which are each connected by a common actuating mechanism. As a result, a greater inspection reliability can be achieved.
