Definitions

  • the present invention relates to a device for adjusting two movable switch tongues arranged between two opposite pole rails.
  • the pawl of a pawl lock is pivotably held on a lock bearing.
  • the switch tongue is also fastened to the locking bearing directly or via an intermediate component, for the adjustment and locking of which the pawl lock is used.
  • the pawl lock therefore has the task of holding the point tongue resting on a stick rail and the point tongue lying off in a geometrically precisely defined position and locking it mechanically.
  • the type of mechanical locking is advantageously carried out in a form-fitting manner. Due to the safety relevance of the functionality described, there are increased demands on the manufacture and maintenance of switches, so that it is a particular task of the design to build the switch lock as simply and safely as possible. Likewise, the same scale applies to the production, which has to provide the necessary parts of the pawl lock without errors.
  • each switch has to be individually adjusted by stocking different locking bearings and locking latches within the scope of the respective adjustability. It is often also unavoidable that holes have to be drilled in the web of the stick rails to attach the locking bearing, which not only requires a great deal of effort when assembling the switch and when managing a large number of components, but also repeatedly leads to comparatively expensive small series in design and manufacture.
  • an external lock for example the pawl lock
  • Such locking pawls are attached to both switch blades by means of a suitable bearing and thus lock the switch blade directly to the stock rail.
  • Such an arrangement in combination with a point machine, ensures safe passage of a rail vehicle. Due to the different track gauges (meter gauge, cape gauge, standard gauge, broad gauge, etc.) and in combination with the high variance of the profiles for switch tongues or stock rails, there is a wide range of geometric requirements for the realization of the external closures mentioned. As a rule, a separate type of closure is required for each design variant, which is suboptimal from the point of view of the design or manufacture of the closures.
  • the present invention is therefore based on the object of specifying a simply designed and functionally reliable pawl lock in which the design can be more easily adapted to the different gauges and profiles of the switch tongues without having to give up the advantageous locking effects of known switch adjustment mechanisms.
  • the inventive value therefore lies in the realization of a universally usable locking unit, which connects the two pole rails in a form-fitting manner via the base plates, which also prevents a track widening in the area of the switch tips.
  • the base plates can be easily adapted for different track widths and/or profiles of the switch tongues and/or stock rails due to the easily drilled holes (template-like) in them, which means that the device can be adapted to comparatively numerous configurations even with only a few parts to be stored.
  • the two base plates can have an internal opening into which the closure unit can be inserted.
  • the locking unit can be designed as a locking box that rests on the base plates with flanges. For easy attachment of the lock box to the base plates, it can be provided that the lock unit can be screwed to the base plates.
  • the area around the switch is often also particularly relevant to safety in relation to its occupancy by a train or its clearing.
  • track circuits are also used for track vacancy detection, the principle of which is based on two electrically isolated stick rails being short-circuited by the axle of a rail vehicle, which can be detected accordingly in the evaluation unit of the track circuit. It is therefore expedient if the closure unit and the base plates can be electrically insulated from one another by means of insulating elements, preferably insulating plates and/or insulating bushings. In this way, the two base plates are each at the tension level of the pole rail to which they are attached.
  • the figure 1 shows a schematic representation of a lateral view of a point adjustment mechanism, which is arranged in a sleeper compartment 12 (ie the space located between two sleeper bodies and left out by the track ballast) which is not shown in any more detail here.
  • a pawl lock is used according to the principle of action in the EP 0 624 508 A1 latch lock shown used.
  • the switch adjustment mechanism is used to adjust two movable switch tongues 6a, 6b arranged between two opposite pole rails 4a, 4b.
  • a base plate 8a, 8b can be fastened to each of the two stick rails 4a, 4b by means of clamping pieces 10a, 10b.
  • the base plates 8a, 8b are aligned largely horizontally and protrude into the threshold compartment 12 located between the two floor rails 4a, 4b figure 2 It can be seen that the two base plates 8a, 8b do not touch in the threshold compartment 12 and are designed in such a way that they offer an opening 14 into which a locking box 16 is inserted.
  • the lock box 16 is bolted to the base plates 8a, 8b using insulating plates and bushings 18.
  • a cam rod 18 is guided, which is not shown here in the direction of an arrow 20 between the two end positions of a switch drive of the switch tongues 6a, 6b is movable.
  • the cam bar 18 fulfills two functions.
  • the tongue-actuating rods 22a, 22b required to move the switch tongues 6a, 6b act on the cam rod 18 via corresponding connecting means.
  • a lock of two locking pawls 24a, 24b is achieved in the locking box 18 in that the cam rod 18 guided in the locking box 16 locks the pivoted locking pawls 24a, 24b in the locking position and thus holds the switch tongues 6a, 6b firmly in their end positions.
  • closure box 16 rests with its flanges on the base plates 8a, 8b and is screwed to them using insulating plates and bushings 18, which are electrically isolated from one another.
