Definitions

  • the invention relates to a retractable switch drive, with a push rod which adjusts the switch tongues, and with a coupling device which is arranged between a drive unit and the push rod and which, in the coupled state, has a holding roller which engages in a recess in the push rod in a spring-loaded state.
  • the object of the present invention is to improve a point machine of the type mentioned in such a way that the disadvantages of the known arrangements are avoided and that, in particular, the coupling device between the drive unit and the push rod can be constructed in a space-saving manner with an equally reliable function.
  • the retaining spring is - as previously mostly - designed as a helical compression spring, but can now be arranged essentially parallel to the push rod, which is optimal in view of the space-saving construction mentioned.
  • the holding roller is mounted at least on one side in a sliding block guided perpendicularly to the push rod in a housing of the coupling device, the two counter rollers being arranged on counter roller housings which can be displaced in the housing of the coupling device parallel to the push rod and which are loaded against one another via the retaining spring are.
  • a further embodiment of the invention has proven particularly advantageous, according to which a single retaining spring on the one hand directly on one of the counter roller housings and on the other hand via a clamping piece with an adjusting screw and transmission bracket engages the other counter roller housing.
  • the desired threshold force for triggering the rigid coupling between the push rod and the drive unit can also be adjusted.
  • FIG. 1 shows a partial cross section through a switch drive according to the invention in the area of the coupling device between the drive unit and push rod, not shown
  • FIG. 2 shows a partial top view of the arrangement according to FIG. 1 from above.
  • a push rod 1 which, if necessary, adjusts the switch tongues (not shown) is movable in the direction of the double arrow 2, the actual drive unit (not shown here) acting on the push rod 1 via a coupling device 3.
  • a left retaining bolt 5 articulated on the housing 4 of the coupling device 3 is latched in a catch 6 on the housing base 7, whereby the associated end position of the switch tongues actuated via the push rod 1 is fixed.
  • a right retaining bolt is designated, which in turn is spring-loaded on the housing 4 and in the right end position of the push rod 1 comes into engagement with a corresponding not shown on the housing base 7.
  • the coupling device 3 has a spring-loaded in the coupled state shown in a Recess 9 of the push rod 1 engaging holding roller 10, which is mounted here on both sides in a sliding block 11 guided perpendicularly to the push rod 1 in the housing 4 of the coupling device 3. Furthermore, two counter-rollers 12, 12 'are provided, which are arranged essentially symmetrically with respect to the direction of movement of the holding roller 10, which are in turn movably mounted substantially perpendicular to the direction of movement of the holding roller 10 and loaded by a retaining spring 13 in the direction of contact with the holding roller 10 are.
  • the retaining spring 13 is designed here as a helical compression spring and is arranged essentially parallel to the push rod 1, which results in a very compact design with a safe function of the coupling device 3.
  • the only retaining spring 13 is supported for this purpose on the one hand directly on the counter-roller housing 14 and on the other hand via a clamping piece 16 with adjusting screw 17 and transmission bracket 18 - here consisting essentially of the two threaded rods 19 and the head pieces 20 - on the other counter-roller housing 15, which is very allows a simple deflection of the effect of the spring force on the load on the holding roller 10.
  • the push rod 1 (with the coupling device and the holding roller 10 held in place via the holding bolts 5 or 8) is pressed with its recess 9 out of the engagement area of the holding roller 10, which causes the holding roller 10 to retreat against the action of the spring-loaded counter rollers 12. 12 'leads, which in turn are pressed apart together with the counter roller housings 14, 15.
  • the push rod 1 is thus freely movable relative to the coupling device 3 or to the drive unit until it matches the position of the holding roller 10 with the recess 9 in turn comes to a coupling.
  • two or more springs which are also designed, for example, as plate springs or the like, could of course also be arranged in a suitable manner, possibly also on both sides of the holding roller 10 - an angle with respect to the illustration would also be possible
