Definitions

the present invention relates to a point adjusting device with a movable frog.
the pawl of a pawl lock is pivotably held on a lock bearing.
the switch tongue or the frog is also attached to the lock bearing directly or via an intermediate component, and the latch lock is used to adjust and lock it.
the latch lock thus has the task of holding the switch tongue resting on an auxiliary rail (stock rail) or the frog point resting on a locking rail as well as the remote switch tongue in a geometrically precisely defined position and locking it mechanically.
the type of mechanical locking is advantageously form-fitting. Due to the safety relevance of the functionality described, there are increased demands on the manufacture and maintenance of points, so that it is a particular task of the design department to set up the point lock as simply and safely as possible. Likewise, the same scale is applied to the production, which has to provide the necessary parts of the latch lock without errors.
the frog point closures currently in use have the problem that the frog point can twist, that is, it can easily tilt or twist from an intended vertical orientation. This rotation makes it possible that the switch lock closes after the cycle, but the frog point does not lock onto the Locking rail is applied.
the assembly instructions stipulate that a sample be taken with a 4mm thick sample, ie that the 4mm thick sample is held as a gauge between the locking rail and the frog tip. The switch lock must then not lock. Since this so-called 4 mm sample could not be reached again and again, an improvement of the anti-twist protection is necessary for a point adjusting device with a movable frog.
the EP 2 557 228 A1 discloses a closure part for such a switch tongue.
FIG. 1 As shown, for this purpose specially shaped closure plates 26 were equipped with height-adjustable blocks 28 which interact with a stop plate 30. When a frog tip 16 is rotated, these blocks 28 are in contact with the stop plate 30, which reliably prevents the closure plates 26 from being lifted and thus twisting the frog tip 16.
the stop plate 30 serving as a height limiter for the blocks 28 can be fastened to the hollow sleeper in the case of a point adjusting device arranged in a hollow sleeper. However, if the point adjusting device is arranged in a sleeper compartment (i.e. between two sleeper bodies), this solution can only be implemented to a limited extent.
the present invention is therefore based on the object of specifying a point adjusting device with a movable frog, in which twisting of the frog tip can be reliably avoided and which can be used both in a hollow sleeper system and in a sleeper compartment.
the closure bearing has two essentially parallel extending pins spaced from one another. In this way, the overall stability in the closed position can be increased because two pegs are now guided under the foot of the auxiliary rail or under the inlet plate attached to the foot of the auxiliary rail.
the position of the inlet plate is adjustable in height by means of a spacer plate.
This spacer plate is mounted under the foot of the auxiliary rail between the foot and the inlet plate and thus changes the height of the inlet plate for the pins guided under the inlet plate.
the Figure 1 shows a schematic representation of a side view of a switch adjusting device, here a pawl lock 2, according to the prior art with a lock carrier 4 and a lock bearing 6.
the pawl lock 2 is moved in one direction or the other by means of a slide rod 12 (also called a cam rod).
a slide rod 12 also called a cam rod.
a frog 16 resting on a locking rail 14 can be seen.
the lock carrier 4 is clamped on a rail foot 18 of an auxiliary rail not shown here.
the clamping hooks 20 used here can be seen very clearly.
the slide rod 12 (also clearly recognizable the cam 22 formed on the slide rod 12) is guided in a sliding manner in the lock carrier 4.
the slide rod 12 is used in both directions of an arrow 24 to adjust the frog 16 and the associated locking pawl 10.
the locking bearing 6 is designed in such a way that, on the one hand, it is fastened to the frog 16 via a locking plate 26 and, on the other hand, it carries the locking pawl 10 in a pivotable manner.
the closure plates 26 have height-adjustable blocks 28 which are in contact with a stop plate 30 if the closure plates 26 should be lifted on one side due to a rotation of the frog 16. As indicated by a dashed vertical axis on the frog 16, this positioning of the blocks 28 on the stop plate 30 prevents the frog 16 from rotating out of this vertical axis.
the stop plate 30 is attached to a hollow sleeper.
the hollow sleeper is a trough-like sleeper body, which has the external dimensions of a normal sleeper body, which enables automatic tamping of the track during track maintenance in the area of the point adjusting device.
the two feet 18 of the auxiliary rails and the stop plate 30 are correspondingly attached to flanges on the side cheeks of the hollow sleeper.
This configuration of the anti-rotation device is problematic when the point adjusting device is arranged in the sleeper compartment.
the threshold compartment denotes here the space between two normal sleeper bodies in which this anti-twist protection solution can only be implemented to a limited extent.
FIG. 2 now schematically in part (a) on the left side the locking bearing 6, as it is in the pawl lock 2 according to FIG Figure 1 is used.
part (b) on the right-hand side a lock bearing 32 according to the invention is shown which, on its side facing the lock carrier 4, has two molded-on pins 34, the function of which is related to FIG Figure 3 is explained in more detail.
the Figure 3 now shows schematically a pawl lock 36 according to the invention on the side of the locked lock pawl 10.
the cam 22 of the slide rod 12 now presses the lock pawl 10 under the foot 18 of an auxiliary rail 38 on the lock carrier 4. In this position, further adjustment of the frog 16 is impossible, since it is now locked by the locking pawl 10 against the locking rail 14.
the pins 34 now run under an inlet plate 40 during the adjustment movement, which is fastened under the foot 18 of the auxiliary rail 38.
the locking bearing 32 is therefore pressed under the foot 18 of the auxiliary rail 38 during the adjustment movement, thanks to the pin 34, and so cannot move upwards.
a spacer plate 42 was also inserted between the rail foot 18 and the inlet plate 40, as a result of which the position of the inlet plate 40 can still be adjusted slightly downwards (if necessary).
the locking bearing 32 with its pin 34 it would also be possible for the locking bearing 32 with its pin 34 to run directly under the rail foot 18 during the adjustment movement.
