Definitions

  • the invention relates to a device for mechanically locking the End positions of movable switch parts, with two adjusting rods, each connected to one of the switch parts and mechanically coupled are, at least one locking piece for locking the actuating rods in one of their end positions and a force limiting device, which releases the lock when the switch parts on the control rods exerted force exceeds a certain value.
  • a device for locking the switch tongues of tram tracks In particular deals the invention with a device for locking the switch tongues of tram tracks.
  • switch setting devices it is important that the movable switch parts are held securely in their respective end positions. If a switch driving is pointed, that is, when the wheels of the rail vehicle come first on the free ends of the switch tongues, one tongue, the so-called tongue, close to the continuous rail, while the other tongue, the so-called remote tongue, is a sufficient one Must be at a distance from the associated continuous rail, so that the wheels can safely pass the switch and not damage it or the rail vehicle derails. on the other hand
  • the switch tongues must be exceeded when a certain one is exceeded Give way to force, so that they avoid the wheels of the rail vehicle can, if the switch is driven bluntly and the switch itself is not in the correct position. Remain with a retractable switch in such a case the switch blades in the newly set position, that is, the switch is made by the wheels of the rail vehicle changed.
  • Switch setting devices are known in which the for adjusting mechanically decoupled from the two switch tongues are and operated directly by the drive of the actuator and can be locked with respective locking clips (e.g. clip tip lock).
  • the adjacent tongue is locked rigidly, e.g. against one Stock rail, while the remote tongue from the self-holding or lockable drive is held.
  • This arrangement has the advantage that the adjacent tongue with a much higher force in its end position can be held as the remote tongue.
  • the disadvantage is the relative high design effort.
  • the drive is not with one Adjusting iron can be changed by hand, and when the switch is opened, the Control rods separated from the drive, so that the drive is actively in the new switch position must be tracked so that the switch is operational again is.
  • An actuating device of the type mentioned at the outset is known in practice (Actuating device HW 60 AVV from Hanning & Kahl), in which the two Control rods are mechanically coupled.
  • the actuator housing is preferably arranged in the middle between the two switch tongues, and the mutually coaxial adjusting rods come from opposite sides forth in the housing.
  • the control rods are through inside the housing a connector rigidly connected.
  • the closure piece is arranged pivotably on the connecting piece and on the one hand cooperates a locking plate coupled to the actuator drive and on the other hand with the force limiting device arranged in the housing together. Due to the force limiting device, both tongues are attached the same holding force held in the respective end position. If this force when the switch is opened, the force limiting device gives after, the lock is unlocked and the switch is inserted into the adjusted new position in which the lock with the help of the closure piece is restored.
  • the object of the invention is to provide a device of the type mentioned create one of the two movable switch parts in each end position (the adjacent tongue) can be held with greater force.
  • the force limiting device by at least one coupling device that yields under stress, which couples the control rods to each other, and through a transmission mechanism, which is the movement of one of the control rods in one movement implemented to unlock the locking piece locking the other actuating rod, is formed.
  • the holding force for one of the movable switch parts is determined by the Force limiting device limited. In practice, this is The soft part usually around the tongue.
  • the control rod for the adjacent tongue is theoretically with the help of the closure piece unlimited power locked on the case. When opening the switch this lock is only released when the remote tongue something has been deflected and this leads to a movement of the associated Control rod has come.
  • the holding force can also be higher than that positioning force required to change the switch.
  • the actuator can be therefore, without reducing the holding force, lay it out so that it easily Hand or with the help of a drive that does not have to be self-holding, can be changed.
  • the closure piece is movable on held a connector, and the coupling device acts between the connector and each of the control rods and there are only when the control rod is loaded in one direction.
  • the two adjusting rods are arranged coaxially to one another, and that Connector is located within the housing of the actuator the free ends of the control rods so that it rigidly supports the control rods. Coupling members are then arranged so that they give way when the associated control rod with sufficient force from the housing is pulled out.
  • the coupling members can, for example, by springs, force-limiting Couplings, clamping members and the like are formed.
  • the transmission mechanism is preferably through a locking plate formed, the driver attached to the free ends of the control rods engages and a locking contour for that held on the connector Has closure piece.
  • This solution has the advantage that the locking of the control rods is not indirectly via a connector, but directly on the housing of the Device is done and not on self-locking effects, but on one Form fit is based. This ensures a high level of functional reliability reached, and the position in which the control rods are locked leaves define yourself precisely and adjust if necessary.
  • two Locking pieces can also be set independently for the two adjusting rods from each other.
  • the closure pieces are preferably designed as strips which extend transversely to extend the control rods and slide over inclined surfaces or by means Rolling elements on and parallel to the control rods Support movable unlocking strips in the longitudinal direction.
  • the locking pieces then perform a pure during the locking and unlocking processes Translation movement.
  • This arrangement is particularly advantageous if the locking device is used in combination with a test facility which is the tongue position with the help of parallel to the control rods arranged test rods scans.
  • the locking device locking pieces can then extend into the test facility and there also serve to lock the test rods, so that an additional Security is achieved.
  • the locking pieces then only fall into the locking position when both the control rods and the test rods are in the correct position. By scanning the position of the locking pieces can thus be obtained a signal that the locked state the actuator by a logical AND with the status signal linked to the testing facility.
  • the release bars interacting with the locking pieces are preferably attached to a slide that is parallel to the control rods is guided in the housing and on which the actuator engages.
  • This carriage is thus the function of the closure plate in the comparable embodiment described first.
  • the closure plate or the carriage can in the housing by a Clamping mechanism be held in the middle position of the closure plate has a dead center and the closure plate on both sides of the dead center preloaded elastically in the respective end position. Because the closure plate is mechanically coupled to the control rods by the drivers the clamping mechanism for the fact that the actuating rods after overcoming the Dead center are automatically transferred to the respective end position. The soft can therefore be very easily with the help of a on the closure plate change the attacking adjusting mechanism.
  • the adjusting mechanism can, for example, manually, magnetically, motorically, hydraulically or pneumatically be operated.
  • the clamping mechanism is used to hold the tightly fitting one Tongue additionally pressed elastically against the associated rail.
  • the holding force for the tongue is additively composed of the Force of the coupling member and the force of the tensioning mechanism.
  • FIG. 1 shows an open half-shell of a housing 10 of a point setting device, the middle between two switch tongues, not shown is arranged.
  • a driver 16 is attached at the free end of each control rod.

This switch tongue is then the adjacent tongue. Because the verb Extension piece 18 in the position shown in Figure 3 by the closure piece 28 and the locking contour 36 on the guide rail 34 fixed to the housing is locked, the adjacent tongue is also locked rigidly in its position.
  • the switch tongue connected to the right adjusting rod 14 is used in the Process described above first by the force of the coupling device 32 and is then added in the final phase ( Figure 3) held in the remote position by the force of the springs 54.
  • the holding power corresponds to the sum of the forces of the coupling device 32 and the springs 54. Since the coupling device 32 by a total of four springs 44, 46 is formed, even if one of these springs breaks still has a high holding force.
