Definitions

  • the invention relates to a point machine according to the Preamble of claim 1.
  • a point machine in the non-collapsible version is in the DE 31 06 708 C1 and in a retractable version in the DE 31 06 704 C1 described in detail.
  • the deflection device takes for the motor rotation in a translatory Slider movement, namely one on a spindle guided spindle nut, at the beginning of each changeover process the introduction of actuating forces in the or the slide valve with a ruler and moves one with this ruler Gate valve from its locked position in which it u. a. the unintentional loosening of a mechanical lock for the one articulated to the respective switch tongue Setting slide prevents from.
  • DE 29 28 194 C2 discloses a retractable turnout drive with outside lock, in which the switching ruler for disengagement sunken gate valve with the backdrop for the Driving the holding clutch is structurally united. Also there, the deflection device first moves the one that has fallen Gate valve out before going through a predetermined free travel on the holding clutch on the single slide valve can act. The locking slides fall with this point machine not only in corresponding recesses of a check valve and lay down from the one or the other side of the holding clutch, but they also fall into the recesses provided for the slide valve a; they thus create an additional mechanical Retaining and monitoring the slide valve.
  • the gate valve in addition to their function as actuating means for the Actuator contacts and as a holder for the setting slide also the function that the positioning force on the or Adjusting slide transmitting coupling piece in its each mechanically hold the end position reached and thus prevent it that the lock through when driving the switch shock-like loads introduced into the drive from the outside can unintentionally solve; this is only possible if the Locking slide gate each when reversing the drive or when opening the switch in the unlocking Position has been disengaged.
  • This function should also Maintained with adjustable slide and tester slides differently designed for the drives Couplings are used against which the Put on the gate valve. None of this makes sense for drives with different stroke lengths adjustable control and monitoring slides to use.
  • the object of the present invention is a point machine to further develop according to the preamble of claim 1, that with him different lengths of stroke are without differently executed actuators and Inspector slide must be kept ready.
  • Different Distances between the interacting gate valves for Use of different adjustment strokes should be possible without measuring work on site according to a predetermined scheme easily and can be set reliably and the once set Distance should be reliably maintained even in rough rail operations stay.
  • the invention solves this problem by the characterizing Features of claim 1.
  • the Gate valve By arranging the Gate valve between guides provided in the housing and bringing in the remaining space between the Spacers filling guides is easy Way possible, the distance between the individual gate valves by inserting correspondingly thick spacer elements, being held between the guides Spacer elements also a subsequent unwanted change prevent the distance between the gate valves.
  • the features of claim 3 include the means to cancel the locks at the beginning of each turnout as Prerequisite for the subsequent slide movement; the length of the ruler is independent of the Length of the actuating stroke to be executed.
  • the disengagement the locking slide over the switching ruler follows the teaching of claim 4, while the coupling piece for Actuating force transmission moves along the driving spindle; the disengagement process must be completed before the actuator clutch according to claim 5 against the clutch housing Holding clutch is running.
  • the drive motor according to claim 6 provided with a gear be different if necessary with gears Number of teeth to be populated.
  • the speed of the adjustment process according to the teaching of claim 7 can also be changed in that the drive motor is designed as a three-phase motor, which controllable frequency converter is to be operated.
  • the claim 8 names the features that the point machine make drivable.
  • the turnout drive according to the invention both left should also be installed to the right of the track, it is from Advantage if he turns the same side of the track, because then the slide valve (s) is only on this side are to be led out of the housing (short housing length). So far, this has not been possible with conventional drives, because the tester slide is always on the tip of the tongue to be arranged on the side facing the adjusting slide are and this arrangement when turning the drive 180 ° is lost. To such a rotation of the drive too achieve, sees the invention according to the teaching of the claim 9 in front, separate guides for Inspector slide on both sides of the control slide to be arranged and the test slide only on the side of the or to arrange the slide valve, which is closer to the tip of the tongue lies.
  • Claims 14 and 15 relate to the attachment of the Point machine on the track.
  • the setting and test slides can be protected within be arranged a threshold. Because of the compact structure it is even possible to use this as well to accommodate within the thresholds.
  • the invention is based on one in the drawing illustrated embodiment explained in more detail.
  • the embodiment shows several in Figures 1 to 4 Section through a point machine with external lock and in Figure 5 a detail for disengaging the Locking slide when starting the point machine.
  • detail 1 shows a vertical section through the drive
  • Figure 2 is a top view of the open drive housing and Figures 3 and 4 one and the other side view of cut open drive housing.
  • the drive housing consists of a preferably metallic Tray 1 and a non-slip and non-slip cover 2, which both accommodate the point machine.
  • Electric motor 3 designed as a three-phase motor moves over a gear stage with the pinion 4, the idler gear 5 and the large wheel 6 a ball screw.
  • This consists of a spindle 7, a guided on the spindle, not shown spindle nut and one the spindle nut comprehensive adjustable power clutch 8.
  • When starting the drive motor moves the spindle nut, non-rotatably longitudinal actuating clutch 8 over an empty travel in the adjustment direction on the spindle 7 until it is on strikes a stop 9 or 10 of a clutch housing 11.
  • This clutch housing is structurally combined with an adjustable one Retaining clutch 12, which has a detent 13th non-positively and positively with the slide valve 14 of the drive connected is.
  • the output speed of the gear stage by exchanging z. B. of intermediate gear and pinion at least change within limits.
  • Another, possibly additional to change the gear ratio of the gear stage Possibility for change to be used the valve speed is the electric motor train as a three-phase motor and controllable To operate frequency converter.
  • the from the spindle 7 and the spindle nut, not shown existing ball screw drive is via roller bearing 15 and a pin 16 connected to the housing trough in the drive housing almost on the fly.
  • Both the power clutch 8 and the holding clutch 12 are limited adjustable. happenss in the holding clutch 12 this by turning one more or less Threaded cap 12.1 in the clutch housing 11 and thereby caused change in pressure of the compressed by the cap Belleville washers.
  • the adjustable power clutch 8 is in the unpublished German patent application P 44 27 809 described in more detail.
  • the from the power clutch 8 applicable force is below in a known manner the retention force of the retention clutch 12 to ensure that the actuating clutch when the specified one is exceeded Actuating force can spin without the holding clutch releases the slide valve.
  • the holding clutch 12 only speaks and releases the setting slide 14 if the switch is opened and high forces from outside be carried into the point machine. On the The process of opening a switch will be closer later received.
  • the slide valve 14 is in a known manner in its two end positions positively and positively.
  • gate valves 17 and 18, which are in corresponding Recesses 19 and 20 of the slide valve 14 occur. This happens under the action of coil springs 21, 22; these coil springs are guided on guide pins 23, 24, over the coil springs against a stop on the inner wall of the housing trough 1.
  • the coil springs are supported in recesses 25 (FIG. 3) the gate valve.
  • the locking slide 17 under the influence of his Coil spring 21 in the recess 19 of the slide valve 14 come up with. It had a drive contact shown in Figure 3 26 changed its switching position and the supply circuit interrupted for the drive motor.
  • the minimum distance between the two guides 27 and 28 is equal to the difference between that to be realized by the drive largest and smallest stroke and the width of the two gate valves.
  • the actuating stroke is the smaller, ever farther apart the two gate valves are.
  • the spacer elements are like the locking slides and the guides run flat so that they are full lie next to each other and the locking slide works independently allow each other from their position without that there will be any canting.
  • the gate valve can be a variety of thinner planer spacers can be used. It is more advantageous however, using spacers of different thicknesses as is also the case in the present exemplary embodiment. Starting from a spacer 32 of the smallest thickness other spacers each twice as thick as the next thinner spacer.
  • the guides can be used to compensate for tolerances 27 and 28 adjustable in the housing or if necessary an additional controllable spacer between the guide 27 and the locking slide 17 to be arranged; This measure does not affect the distance between the gate valves and therefore not the length of the set stroke.
  • the switch drive according to the invention nor check valve 33, 34 which serve the actual Position of the switch elements controlled by the setting slide on the Point machine to report back.

  • the check valve 33, 34 like the adjusting slide 14, have a rectangular shape Cross section and are able to relatively large forces between to transfer the turnout elements and the turnout drive. In addition to monitoring the position, they also serve to drive the Switch elements in their respective end positions to hold on and so a predetermined track width between the To ensure rails of a switch.
  • the gate valve can be in the other end position of the drive 18 with his nose 18.1 only in the recess 20 of the Adjusting slide 14 occur, if at the same time the nose 18.2 of the locking slide in a recess provided for this purpose 37 of the slide valve 33 can occur.
  • This recess 37 is considerably wider in the longitudinal direction of the slide valve 33 than due to the width of the nose 18.2 of the locking slide 18 is; this will be described later in the description of the opening process discussed in more detail.
  • the two movable switch tongues in their other end positions are used in their shape of the recess 35 corresponding recess 36 in the tester slide 34, via which the switch tongue then attached is monitored and a correspondingly wide recess 38 for monitoring the remote switch tongue.
  • the recess 38 of the test slide 34 so wide that the tester slide is moving can, without being blocked by the locking slide 17.
  • the nose 17.1 of the locking slide 17 is finally out of the Recess 19 of slide valve 14 completely disengaged, the locking slide 17 also has the test slide 34 completely released so that this the further movement of the can follow remote switch tongue.
  • the locking is similar to opening the switch the one that has fallen into the actuating slide and the inspection slide Locking slide also released with every switch changeover.
  • one of the actuating force clutch 8 is used when starting each of the actuator can be moved in the setting direction 39 ( Figure 5), which is designed to be on the way the actuating clutch between its starting position at the beginning an adjustment process and hitting the stop 9 and 10 of the clutch housing 11 each in the actuating and the check slider sunken locking slide 17, 18 from the recesses of these sliders disengages.
