Definitions

  • the present invention relates to a latch lock for the setting tongues of railway switches, which has a locking pawl which can be actuated by means of a slide rod and a locking piece, the locking pawl being pivotably arranged in a locking bearing and the adjusting tongue being fastened to the upper end of the locking bearing.
  • Lock bearings of this type are used in railway switches in order to pull the tongue tips to the adjacent rail flank and to hold them there.
  • the positioning tongues are slidable over a certain length on the rail sleepers.
  • One end merges into rail sections firmly connected to the sleepers, while the tip of the tongue can be moved by means of a device.
  • the tip of the tongue In the closed position, the tip of the tongue is pulled up to the adjacent rail flank and held or held there. bracketed while it is positioned in the open position a certain distance from the rail flank.
  • Convention switches such a lock bearing works satisfactorily.
  • the object of the present invention was to improve the known latch lock in such a way that the problems described above are eliminated.
  • lock bearing bears in a form-fitting manner on the lock piece in the closed position of the lock pawl. This prevents the lock bearing from rotating. This also prevents the positioning tongue from being twisted and lifted off the rail flank with this twisting. that there is a gap between the rail flank and the tip of the tongue.
  • a preferred embodiment of the invention is characterized in that the foot of the locking bearing has an extension projecting in the direction of the locking piece, the free end of which rests on the foot of the locking piece in the closed position of the locking pawl. This simple measure advantageously effectively prevents the locking bearing from rotating.
  • the closure according to the invention is advantageously suitable for being accommodated in a box threshold.
  • the entire turnout drive can be accommodated in this threshold, which considerably simplifies the ballast processing of the track bed in these areas.
  • the ballast With a conventional arrangement of the drive between two sleepers, the ballast must be manually processed in this area, for example during maintenance. This means that the rails or the sleepers cannot be shaken sufficiently into the gravel, resp. the ballast cannot provide enough support, which means that the rails can vibrate more in this area.
  • a conventional latch lock for a railway switch is shown in Figure 1.
  • a locking piece 2 is attached to a rail 1 on one side of the rail foot by means of retaining clips 3 which hook under the rail on the other side of the rail foot.
  • the setting tongue 4 of the switch is connected at its free end to a lock bearing 5.
  • the adjusting tongue 4 is shown here in the open position, ie the adjusting tongue 4 is pulled away from the rail flank. A train traveling over the switch would be guided in the direction of the rail 1.
  • On the locking bearing 5, a locking pawl 6 is pivotally arranged in a bearing 7.
  • a slide rod 8 is provided for the adjustment of the adjusting tongue 4.
  • the slide rod 8 is moved transversely to the longitudinal axis of the rail by means of a drive, not shown.
  • the latch 6 and the slide rod 8 are now designed such that the free end of the locking pawl 6 can slide under the foot of the rail 1 as shown in FIG.
  • the slide rod 8 is moved against the rail 1.
  • the locking pawl 6 is also carried in this direction by its edge 8 ′, as a result of which the setting tongue 4 is finally moved against the rail 1. Due to the design of the slide rod 8 and the locking pawl 6, this is printed against the top as soon as the positioning tongue 4 rests on the flank of the rail 1.
  • the blocking surface 6 'of the locking pawl 6 thus comes into contact with the locking piece 2, as shown in FIG. 2. In this position, the switch is closed and a train would now be directed in the direction of the positioning tongue 4.
  • This latch lock now causes the setting tongue 4 to be positively connected to the rail 1 via the latch 6 in the closed position.
  • the setting of this connection can be achieved, for example, in that the bearing 7 has an adjustment option by means of an eccentric.
  • the alignment of the locking pawl 6 can thus be set or readjusted such that the locking surface 6 ′ rests with a defined play on the locking piece 2 when the adjusting tongue 4 rests on the flank of the rail 1.
  • a web 9 can be provided on the foot of the locking bearing 5, which comes into contact with the foot of the locking piece 2 in the closed position of the pawl, as shown in FIG. 4. This measure effectively prevents twisting and thus lifting of the positioning tongue 4 from the flank of the rail 1.
  • a latch lock according to the invention is particularly suitable for switches which are used for high-speed lines.
  • Such turnouts have very large curve radii so that the trains can pass this turnout at high speeds.
  • This in turn means that the positioning tongues have very large free lengths, for example up to 40 meters. This increases the likelihood of the tip of the tongue twisting, all the more because the high drive-through speeds cause vibrations to be generated by the wheels with very high intensity. It is therefore very important that the positioning tongue can be guaranteed to rest reliably without the risk of it lifting off the flank of the rail.
  • a plurality of latch locks are preferably provided in succession on an adjusting tongue, so that the adjusting tongue can be moved and positioned reliably.
  • the latch lock according to the invention is nevertheless suitable for this.
