Definitions

  • the invention relates to a device for functional testing of devices for the conversion of movable switch parts, in which the movable switch parts are connected to each other via a coupling rod.
  • a device for the conversion of movable switch parts is for example from the AT 405 925 B known.
  • two relatively axially displaceable parts are displaceable in a non-positively coupled at least in one direction coupled to each other position
  • the relatively movable parts are formed by a tube and a rod guided in the tube and at least partially disposed in a stationary outer tube.
  • the locking members for the end position locking are formed by balls, which cooperate with the mutually axially displaceable parts and the outer tube and are displaceable in the radial direction in a locking position in a recess or êtringnut the outer tube.
  • the guided in the tube rod is at the same time designed as a piston rod for a hydraulic cylinder piston unit, so that from the AT 405 925 B known device not only ensures an end position lock for moving switch parts, but also causes the conversion of the switch.
  • a rigid coupling rod is provided in the known device, via which the switch tongues are connected, so that when an adjustment of a tongue, the correspondingly corresponding movement of the second tongue is frictionally ensured.
  • the hitherto known safety devices are not sufficient and it is therefore an object of the present invention to provide a device with which an additional functional test of devices for the Conversion and Endlagenverriegelung movable switch parts is possible.
  • the invention aims to provide an additional mechanical function control in which any deviation of the tongue position from the respective target position and any malfunction of Endlagenverriegelung can be monitored directly electronically and in which due to the generated signals can be directly closed to the exact cause of the error.
  • the inventive construction consists essentially in the fact that the coupling rod consists of two axially displaceable relative to each other bar parts and that sensors for the detection of at least two mutually different displacement positions of Coupling rod parts are arranged.
  • the coupling rod consists of two axially displaceable relative to each other bar parts and that sensors for the detection of at least two mutually different displacement positions of Coupling rod parts are arranged.
  • a two-part coupling rod is provided, whose two parts are displaceable relative to each other in the axial direction, the axial length of the coupling rod changes during the Umstellvorganges the switch and it is thereby created the opportunity during the switching sensor signals to generate which the different displacement positions play the coupling rod parts to each other.
  • sensors for detecting at least two mutually different displacement positions of the coupling rod parts are therefore provided.
  • such a two-part coupling rod is in the use of switching devices in which the movable switch parts are not synchronous, ie, for example, moved via a rigid coupling rod, but at which first the remote tongue unlocked and moved over a first partial path, whereupon the changeover process for the adjacent tongue begins.
  • a changeover device has the advantage that the respective tongue located in the system is held longer in this position, even during the beginning of the changeover process.
  • the coupling rod parts so move so that the coupling rod is initially longer at the beginning of the Umstellvorganges, then retains its length and reaches its original length at the end of the Umstellvorganges.
  • the sensors can signal during the entire Umstellvorganges thus at least three switching operations, so that a nearly continuous function verification of the changeover is guaranteed.
  • a second control level can be realized with the inventive verification device and thus also a statement about the cause of any error can be made.
  • a preferred embodiment of the device according to the invention is that the coupling rod parts have stops for limiting the axial mutual displaceability.
  • a coupling rod part on a tubular at least one axial portion of the other coupling rod part encompassing part.
  • Such a design allows a coaxial arrangement of the one rod member within the tubular part of the other coupling rod part, so that an overall encapsulated, outwardly closed device is provided, within which also the sensors and other components can be arranged protected from external influences.
  • the tubular part of a coupling rod part in this case has a stop which engages behind a piston-shaped end piece of the other coupling rod part.
  • a precise stop is defined in a simple manner, which defines the maximum length of the coupling rod.
  • the coupling rod parts are connected to each other via a spring, in particular a helical spring.
  • a spring in particular a helical spring.
  • the sensors are designed as contact switches, so that the reliability of such sensors can be further increased and a corresponding signal is reliably generated only when the corresponding end position is reached.
  • a first sensor is rigidly connected to a coupling rod part, wherein the sensor for detecting a first displacement end position of the coupling rod parts cooperates with an actuator disposed on the tubular part.
  • This sensor is thus arranged such that it is displaceable together with a coupling rod part relative to the other coupling rod part and upon reaching a Verschiebendlage, ie when the stops cooperate to limit the change in length of the coupling rod, cooperating with a tubular member arranged on the rigid actuator and on this type generates a signal.
  • a second sensor is preferably rigidly connected to a coupling rod part, wherein this second sensor for detecting a second displacement end position of the coupling rod parts cooperates with an abutment surface arranged inside the tubular part, wherein the abutment surface within the tubular part can also be mounted resiliently displaceable relative thereto.
  • Such resilient mounting of the abutment surface for the second sensor which signals the Verschiebendlage, which corresponds to the system of tongues, has the advantage that an elastic deflection of the adjacent tongue, which can be triggered, for example, by driving over a train, does not trigger a switching signal , since the spring-mounted stop surface follows this resilient movement of the tongue.
  • the design is such that the attacks are arranged displaceably.
  • the given by the stops limiting the change in length of the piston rod can be adjusted so that an adjustment of the test device can be made to the conditions given by the Umstell- and locking device respectively.
  • the piston-shaped end piece is connected in an advantageous manner via a thread with a coupling rod part, wherein furthermore also the tubular part can be connected via a thread with a coupling rod part.
  • the sensors are advantageously connected to an evaluation and monitoring device.
  • an evaluation and monitoring device can also be supplied with the signals of other sensors, so that a detailed error analysis can be carried out.
  • FIG. 1 a point changeover device with a coupling rod
  • Fig. 2 an enlarged view of the left side of the switching device according to Fig. 1
  • Fig. 3 an enlarged view of the right side of the changeover according to Fig. 1
  • Fig. 4 a partial view of the coupling rod in section.
  • Fig. 1 is a stock rail 1 can be seen, with 2 a voltage applied to the stock rail 1 switch blade is shown.
  • the remote switch tongue is designated 3.
  • the changeover device 4 in this case comprises an outboard tube 5, which extends on both sides of a central region, which is designed as a cylinder 6.
  • the piston 7 is connected to a continuous piston rod 10, which has different cross-sectional areas over its axial length.
  • tubes 11 are provided, which are connected via terminal devices 12 with the switch blades 2 and 3 respectively.
  • Fig. 1 is further a coupling rod 13 can be seen, which consists of the rod parts 14 and 15.
  • the parts 14 and 15 are each coupled to a part of the connecting device 12 connected to the switch tongue 2 or 3.
  • the encapsulated part 16 of the coupling rod 13 is in Fig. 4 shown in more detail and described in more detail below.
  • Fig. 2 and 3 now the operation of the changeover and locking mechanism is shown in more detail.
  • Fig. 2 illustrated left side of the Fig. 1 it is the side which is responsible for the locking position of the remote tongue 3.
  • the locking elements which are formed by an expandable ring 17 and the associated balls 18 are held by an axial region 19 of the piston rod 10 in the locking position against a stop 20 in a recess 21 of the outer tube 5, wherein a displacement of the with Tongue 3 connected pipe 11 from the remote position of the tongue is prevented in a plant position by the stop 20 and the ring 17.
  • the piston rod 10 enters a position in which the outer located in the locking position ring 26 can escape under the force of its spring 27 with the associated balls 25 on the smaller diameter offset end portion 28 of the coupling rod 10 from the locking position, creating a relative displacement the tubular part 11 with respect to the outer tube 5 is made possible.
  • the inner stop shoulder 29 of the formed with a full cross-section axial region 19 is usually not in operative connection with the balls 18, since the entrainment of the tongue 2 via the coupling rod thirteenth he follows.
  • the overlap lengths of the closure members can in this case for example be chosen such that after a piston adjustment of 14 mm (a) an active adjustment of the remote tongue 3 begins, so that entrainment of the coupling rod member 14 takes place through the remote tongue 3.
  • the coupling rod part 15 is in this case connected via a thread with a tubular part 30 which engages around the coupling rod part 14.
  • Connected to the coupling rod part 14 is a piston-shaped end piece 31, which is engaged behind by a stop 32 of the tubular part 30.
  • a distance b is provided at the beginning of the changeover process.
  • a piston stroke of, for example, 12 mm now comes the piston-shaped end piece 31 in abutment against the stop 32 of the tubular member 30, so that the coupling rod member 15 and thus the adjacent Tongue 2 is taken.
  • the closure of the adjacent tongue 2 is already unlocked, so that the tongue 2 is moved from the system into the tray via the coupling rod.
  • the length c must be greater than the sum of the lengths a and b.
  • the annular contact part 36 is resiliently mounted within the tubular member 30 via a spring 40.
  • a spring 41 is provided between the coupling rod part 15 and the end piece 31 of the other coupling rod part 14. In a breakage of the coupling rod causes the spring 41, that the distance b between the stops 32 and 33 is maintained. In this way, a relative displacement of the coupling rod parts 14 and 15 to each other can be avoided, so that in this case the contact switches 34 and 35 do not trigger signals. Overall, the two coupling rod parts 14 and 15 are secured by a nut 42.
