Definitions

  • the invention relates to a device for locking a switch tongue with a stock rail, a locking element effecting the locking starting from the switch tongue or from a tongue block.
  • a corresponding device with an adjusting rod, which lead to the switch tongues, has an angle lever is known from DE-B-930 454.
  • the stock rail and angle lever do not always have to be at a defined distance, this can change unintentionally or uncontrollably.
  • the same problems occur with switch locking systems, as are indicated in DE-A-33 878, DE-A-252 508 or FR-A-881 749.
  • the object of the present invention is to design a device of the type mentioned at the outset in such a way that a structurally simple means can be used to securely close a switch tongue, the locking remaining without additional safety measures even if a force acts on the switch tongue the stock rail is turned away.
  • the third axis (A) is arranged on or at a defined, non-changeable distance from the stock rail, that by rotating the rotating element into a first end position, the locking element can be pivoted in such a way that a constant contact causing the locking Switch tongue can be effected on the stock rail, and that when the rotary element is rotated into the first end position, the first and second axes (B, C) are aligned with respect to the third axis (A) in such a way that a force exerted by the switch tongue acts on the closure element Unlocking counteracts.
  • the first, second and third axes in the closed position are oriented as follows.
  • the connecting line between the first and second axes lies outside the third axis in the region of a stop which prevents the rotary movement of the rotary element when it is in the first end position. If a force acting in the direction of the connecting line between the first and second axes now acts on the closure element from the tongue, the rotary element is pressed further against the stop, which ultimately causes the switch tongue to be pulled further towards the stock rail. Only when the connecting line between the first and second axes is moved away from the stop via the third axis can the switch tongue be opened by the stock rail. The switch tongue is removed from the stock rail in that a force acts on the rotary element which rotated the rotating element about the third axis and thus the closure element is pivoted about the first axis.
  • the teaching according to the invention consequently proposes a device in which, when the switch tongue and stock rail are locked, they form a unit, which, for. B. cannot be canceled uncontrollably by a change in position of one of the elements.
  • the locking element is preferably a rod-shaped or rod-shaped locking lever, in the end sections of which the first and second axes run.
  • the rotating element which, if necessary, for. B. can be formed as a disc, preferably consists of two rigidly interconnected first and second legs that describe an angle ⁇ to each other.
  • the rotary element can therefore be referred to as an angle lever.
  • the third axis which is fixed to the stock rail, for example in a fastening element extending from the stock rail, preferably runs at the intersection of the legs, whereas the second axis runs in the first or second leg, preferably in the respective free end region.
  • an adjusting element such as a push rod acts on the second leg to rotate the rotary element, that is to say the angle lever.
  • the push rod is connected to the rotary element in an articulated manner about a first axis and can be actuated, for example, by means of a servomotor in order to bring about the rotary element and consequently the switch tongue movement.
  • the closure element, rotating element and adjusting element run below the stock rail and the switch tongue.
  • the switch tongue is already in contact with the stock rail when the connecting line between the first and second axes lies in one plane with the third axis.
  • the locking element can be elastically mounted in the switch tongue or the tongue block and / or the switch tongue itself is elastically twisted during this movement.
  • the device according to the invention also has the advantage that, for example, with a relative length shift between the stock rail and switch tongue, in the direction of the third axis and stop, the switch tongue is further tightened to the stock rail, since the connecting line between the first and second axes continues away from the third axis. If, on the other hand, there is a length shift in the opposite direction, the connecting line first / second axis could exceed the zero point position, so that the locking mechanism then no longer offers the necessary security against uncontrolled opening.
  • a stop originates from the switch tongue, preferably the tongue block, which can interact with a protrusion extending from the stock rail, which is preferably arranged on the fastening element for the rotating element. The projection and stop interfere when the switch tongue to the stock rail is extended to an unacceptable extent in the direction described above. Due to the interaction of the stop and the projection, it is then no longer possible to adjust the switch tongue, which triggers a fault message.
  • FIG. 1 shows an example of a device for locking a switch in the area of a switch tongue 12 and a stock rail 10, in which the switch tongue 12 is opened to the stock rail 10. Furthermore, in the exemplary embodiment, the turnout start WA should be on the left and the turnout end WE on the right.
  • a locking element such as locking lever 16 extends, which can be pivoted about an axis B.
  • the other end of the locking lever 16 is pivotally connected about an axis C to a rotary element such as angled lever 18, which in turn is rotatable about an axis A which is arranged in a fixed manner with respect to the stock rail 10.
  • the axis A according to the embodiment according to FIG.
  • the angle lever 18 comprises two legs 22 and 24, at the intersection of which the axis A runs. If the leg 22 is articulated in the axis C to the locking lever 16, a push rod 26 extends from the free end of the leg 24 and is connected to the leg 22 in the D axis. Because the legs 22, 24 are rigidly connected to one another, their longitudinal axes describe an angle to one another. As a result, the distance A - C - D is fixed and unchangeable.
  • the following data are given, for example: ⁇ ⁇ 40 °, X% e 160 mm, L ⁇ 132 mm and Y ⁇ 353 mm.
  • the actuating element or the push rod 26 can be moved in the direction of the arrow by means of a servomotor, not shown. If the push rod 26 is displaced in the direction of the stock rail 10, the rotary element 18 rotates about the axis A. At the same time, the axis C moves along the dashed circle 30 with the radius X. This results in the switch tongue 12 being pulled towards the stock rail 10 The switch tongue 12 is already in contact with the stock rail 10 before the connecting line between the axes B and C lies in a common plane with the axis A which runs predominantly perpendicular to the longitudinal axis of the stock rail (32).
  • the switch tongue 12 is pulled further in the direction of the stock rail 10 until the connecting lines between the axes D and C lie in a common plane with the axis A, which runs predominantly perpendicular to the stock rail longitudinal axis.
  • This can be made possible by the fact that the closure element 16 is mounted elastically in the switch tongue 12 or in the tongue block 14 or that the switch tongue 12 itself is elastically twisted.
  • the rotating element 22 In order to allow the tongue 12 to open, the rotating element 22 must be rotated counterclockwise about the axis A by moving the adjusting element 26 away from the stock rail 10, so that the connecting line B - C exceeds the zero point position 32, whereupon the switch tongue 12 closes the stock rail 10 can be opened.
  • the device according to the invention has the further advantage that the turnout cannot be unlocked in the locked state even if, for example, the turnout tongue should move towards the stock rail 10 in the direction of the turnout start WA.
  • the connecting line B - C would only move further from the axis A and thus from the zero point line 32 to the left, as a result of which the switch tongue would be pulled further towards the stock rail 10.
  • a switch can be locked with structurally simple means without the need for locking hooks, clamps or the like. (Of course, a corresponding device according to the invention is arranged on the opposing stock rail or switch tongue of the switch.)
  • FIG. 3 shows that the actuating element 26, the angle lever 18 and the locking lever 16 run below the stock rail 10 and the switch tongue 12.
  • the locking lever 16 is rotatable about the axis B by the tongue block 14 and the angle lever 18 rotatable about the axis A from the fastening element 20, which starts from the stock rail 10 taken.
  • the elements 16, 18, 26 run in different planes, so that a mutual hindrance cannot occur when rotating or pivoting.
  • a stop 34 extends from the tongue block 14 below the push rod 26, which then interacts with a projection 36 starting from the fastening element when the switch tongue 12 in the exemplary embodiment should have moved in the direction of the switch end to the stock rail 10.
  • the connecting line B - C can run to the right of the axis A when the leg 22 abuts the stop 28, as a result of which a firm locking would not be guaranteed; because when force is applied in the direction of the switch tongue, the rotating element 18 would easily be rotatable in a clockwise direction about the axis A, as a result of which the switch tongue 12 would open.
  • the stop 34 and the projection 36 act together when an inadmissible displacement of the stock rail 10 and switch tongue 12 relative to one another should have taken place.
  • the stop 34 would already abut the projection 36 before the locking of the turnout fence and then via a guide or the like, not shown. generate a warning signal which indicates that the turnout cannot be locked.
  • angle lever 18 is reproduced in the exemplary embodiment in FIG. 3 in such a way that its legs 22, 24 run in one plane, it is made clear by FIG. 5 that these also have forks 38, 40 with the closure element 16 or the actuating element 26 can be connected in order to ensure a safe interaction in the area of the axes C and D.
  • the legs 22 and 22 run in planes offset parallel to one another.
  • angle lever as a rotating element 18
  • a circular element which can be rotated about an axis which is fixed with respect to the stock rail 10 and which has a fixed geometric relationship with the articulation points of the closure element 16 and actuator 26.
  • the circular element must of course also hit a stop corresponding to the stop 28 when the closure element 16 has exceeded the previously discussed zero position.
  • the zero point position 32 to the right of the stop 28 has been described in the exemplary embodiment, it can also run to the left of the stop 28 if the axes C, D are changed accordingly, the rotary element then having to be turned clockwise if the unlocking is to take place.
