Definitions

  • the invention relates to a closure for switch machines.
  • Turnouts for rail vehicles have two switch points, which are pivotally located between so-called stock rails of a switch and can be adjusted in the direction transverse to the stock rails with the aid of the points setter.
  • the adjacent tongue In each stationary state of the switch machine is one of the two switch blades on the associated stock rail. It is therefore called the adjacent tongue.
  • the other switch tongue is referred to as a remote tongue, since its free end to the associated stock rail has a certain distance.
  • the closure serves to positively block the adjacent switch blade in the adjacent position, so that they can not be moved away from the stock rail, as this could lead to derailment of the rail vehicle.
  • the point setting device must therefore have an unlocking mechanism which unlocks the closure before the actual changeover process can begin.
  • the object of the invention is to provide a novel closure for switches setting devices, which is characterized by a high reliability and a compact design.
  • a closure piece which forms a running in the adjustment direction of the switch guide slot and a transversely outgoing from the guide slot locking seat, a hingedly connected to an adjacent switch tongue locking lever which carries at the remote from the switch blade end lockable on the locking seat locking pin, a guide pin slidable in the guide slot, a hinge pin connected to a distal switch tongue, a bracket pivotable about the axis of the guide pin, and in which the lock pin, guide pin and hinge pin are supported in a triangular configuration such that the lock pin and the hinge pin lie on opposite sides of the guide slot and the adjacent switch blade are closer than the guide pin, and a spring that vors the remote switch blade towards its remote position panning one.
  • Figure 1 is a schematic section through a switch and an associated Weichenstellvorraum.
  • FIG. 2 shows the point setting device according to FIG. 1 in plan view
  • FIGS. 3 to 5 are sectional views similar to FIG. 1, for different operating states of the point setting device.
  • a switch 10 for rail vehicles, a closure 12 of an associated switch device are shown.
  • the switch 10 has two stock rails 14, 16 and two switch blades 18, 20.
  • the switch blade 18 abuts against the stock rail 14 (adjacent tongue), while the switch blade 20 is moved away from the stock rail 16 (tongue off).
  • the closure 12 has a stationary between the jaw rails 14, 16 arranged closure piece 22 which forms a transverse to the cheek rails guide slot 24.
  • the guide slot 24 is formed by a straight on a majority of its length in a wall of the closure piece 22 extending slot, which is at one end, left in Fig. 1, extended so that a transversely from the guide slot 24 outgoing locking seat 26 for a Arresting pin 28 is formed.
  • the locking pin 28 is seated at the free end of a Z-shaped angled locking lever 30 which is connected at the other end by a hinge 32 with the adjacent switch blade 18.
  • the locking lever 30 and the locking bolt 28 resting against the locking seat 26 thus ensure that the adjoining switch points ge 18 positively locked in the adjacent position. Since the axis of the hinge 32 is horizontal and the locking seat 26 is formed on the underside of the guide slot 24, the weight of the locking lever 30 contributes to the fact that the locking pin 28 reliably engages in the locking position.
  • the locking pin 28 is held in a bearing block 34, which also receives a guide pin 36 and a hinge pin 38.
  • the hinge pin 38 connects the bearing block 34 articulated to a connecting member 40, which in turn is connected via a hinge 42 with the remote switch blade 20.
  • the axes of the locking pin 28, the guide pin 36 and the hinge pin 38 form a triangle.
  • the guide pin 36 is slidably guided in the guide slot 24.
  • the locking pin 28 and the hinge pin 38 are offset from the guide pin 36 to the adjacent switch blade 18 out and lie on opposite sides (below and above) of the central axis of the guide slot 24th
  • the connecting member 40 has in the middle between the hinge pin 38 and the joint 42 on a downwardly projecting lug 44 on which a spring 46 engages via a hinge 46.
  • the other end of the spring 48 is connected in the example shown here via a control rod 50 with a drive, not shown, of the point setting device.
  • the entire closure 12 is housed in a box-shaped housing 52, which is arranged below the stock rails 14, 16 and in the area between the stock rails slightly higher drawn side walls, between which the closure piece 22 is held.
  • the closure 12 has a total symmetrical structure, wherein the plane of symmetry by the locking lever 30 and the connecting member 40 is defined.
  • the closure piece 22 has in plan a C-shaped configuration with lying symmetrically to the locking lever 30 side walls in which the slots are formed, which are the chiefsku- form lisse 24.
  • these slots can also be formed congruently in the walls of the housing 52, so that the housing 52 can be considered as part of the closure piece.
  • the locking pin 28 passes through the entire housing 52. Its middle part is covered in Fig. 2 by the overlying hinge pin 38.
  • the bearing block 34 and the guide pin 36 are each formed by two separate parts due to the symmetrical structure, which lie on both sides of the plane of symmetry. Each part of the guide pin 36 extends through the guide slot 24 and is mounted in the associated part of the bearing block 34.
  • the hinge pin 38 connects the connecting member 40 with the two parts of the bearing block 34, but does not quite reach the walls of the closure piece 22, in which the guide slot 24 is formed.
  • the spring 48 is formed by two symmetrically arranged spring elements which engage the common joint 46. The other ends of these spring elements are connected to the control rod 50 by a shaft 54 which is guided in slots (not shown) in the walls of the housing 52.
  • the shutter 12 is unlocked when the switch is opened, that is, when a rail vehicle displaces the remote switch blade 20 toward the associated stock rail 16.
  • a pulling force directed to the right in FIG. 1 is then exerted on the connecting member 40.
  • the spring 48 is a tension spring, which can yield under this force, so that the joint 46 can shift further to the right in Fig. 1.
  • Also on the hinge pin 38 held in the bearing block 34 acts a rightward traction.
  • the bearing block 34 can not yield to this force because it also supports the locking pin 28, which is still caught on the locking seat 26.
  • the adjacent switch blade 18 thus initially remains blocked in its adjacent position.
  • the tensile force exerted on the hinge pin 38 results in a torque tending to pivot the bearing block 34 in the clockwise direction in FIG.
  • the locking pin 28 is caught on the locking seat 26 and the guide pin 36, which is also mounted in the bearing block 34, is supported on the lower edge of the guide slot 24, pivot the bearing block 34 and the hinge pin 38 about the axis of the guide pin 36.
  • the locking pin 28th is levered out of the locking seat 26. Since the guide pin 36 is slidable in the guide slot 24, the pivotal movement of the bearing block 34, a translation to the right in Fig. 1 are superimposed, so that the locking pin 28 does not need to move to the left during the pivoting movement, which by the at the switch blade 18 supported locking lever 30 would be prevented.
  • a certain bearing clearance and a certain play of the guide pin 36 in the guide slot 24 contribute to the fact that it does not lead to jamming of the bearing block 34 in the described process.
  • Fig. 3 the state is shown in which the bearing block 34 has been pivoted so far that the locking pin 28 is released from the locking seat 26 and is located in the guide slot 24.
  • the exact contour of the locking seat 26 can therefore be seen more clearly in FIG.
  • the remote switch tongue 20 and the connecting member 40 have moved slightly to the right in Fig. 3.
  • the link has been slightly pivoted about the hinge 42 because the bearing pin 38 has lifted.
  • the hinge 46, on which the spring 48 engages, has also shifted slightly to the right. Since the control rod 50 was not actuated when driving the switch, the spring 48 has been pulled out slightly.
  • Fig. 4 shows the state at the end of Auffahrvorgangs.
  • the switch tongue 20 now bears against the stock rail 16, while the switch tongue 18 has moved away from the stock rail 14.
  • the guide pin 36 has moved to the right end of the guide slot 24.
  • the locking pin 28 lies with its ends on the straight-line fenden upper edge of the guide slot 24 and has thus prevented further pivoting of the bearing block 34, so that the bearing block 34 has carried out a pure translational movement.
  • the spring 48 is extended and thus is under considerable tension.
  • the switch can return to the starting position shown in Fig. 1 due to the restoring force of the spring 48.
  • the locking pin 28 Towards the end of this movement, the locking pin 28 again falls on the locking seat 26, partly because of the dead weight of the locking lever 30, but mainly because of the force exerted by the bearing pin 28 on the bearing block 34 torque, which now acts in the counterclockwise direction.
  • the central axis of this locking pin 28 is slightly lower than the lower edge of the guide slot 24. If a rightward force is exerted by the switch blade 18 on the locking pin, this can not over the lock seat 26 are lifted away, but it is held self-locking on the lock seat 26.
  • the self-locking is reinforced in the example shown still by the fact that the locking lever 30 has a Z-shaped configuration, so that a rightward force acting on the hinge 32, together with the resistance of the locking seat 26 generates a clockwise torque, the presses the locking pin 28 deeper into the recess at the end of the guide slot 24, which forms the locking seat 26.
  • this shape of the locking lever 30 has the consequence that the locking pin 28 must move slightly to the right during the unlocking process.
  • the contour of the locking seat 26 may be selected so that on the one hand this movement allows, on the other hand, however, ensures the self-locking when the force is applied via the locking lever 30 and the locking pin is not raised by the pivotal movement of the bearing block 34.
  • Fig. 5 illustrates the case that the switch is not driven up, but with the help of acting on the control rod 50 (not shown) actuator is actively switched by the control rod 50 is moved to the right in Fig. 5.
  • the spring 48 is in This example is designed so that it is in the initial state of FIG. 1 on block, so that they can transmit shear forces.
  • the force of the control rod 50 is then transmitted by the spring 48 on the hinge 46 and further via the connecting member 40 on the bearing pin 38.
  • the unlocking can then be effected in the same manner as described above in connection with FIGS. 1 and 3.
  • the switch blade 20 is then moved by means of the control rod 50 and the spring 48 in the applied position.
  • a second shutter may be provided for the switch blade 20 that is identical in construction to the shutter 12 described herein, but (except for the spring 48 and the control rod 50) is disposed in mirror image relation thereto.
  • the springs 48 should then be designed so that they are not in the state shown in Fig. 1 and Fig. 5, not in the block, but in the neutral position from which they can both be stretched and compressed, so that a departure of the switch is also possible if the switch blade 20 is the adjacent tongue.
