Definitions

  • Tongue lifting device for adjusting switch tongues
  • the invention relates to a tongue lifting device for adjusting switch tongues, with a bearing block for attaching the tongue lifting device to a stock rail and with at least one roller carriage for storing at least one roller, the switch tongue resting on the roller at least during adjustment, and wherein the roller slide on at least one on the Bearing block is supported on the positioning disc.
  • EP 0 674 049 B1 discloses a tongue lifting device with rollers arranged in a downward free chamber for supporting the tongue of a switch, the tongue lifting device being adjustable in height and arranged in the threshold area and the rail foot of the stock rail being fastened to the rail under it.
  • the known tongue lifting device is firmly fixed to the rail base of the stock rail by means of a clamping device.
  • the axes of the rollers are guided together on both sides in a height-adjustable guide piece, which is inserted into and connected to the side pockets of the roller housing that are open at the top.
  • adjustment inserts can be inserted between the bottom surface of the pockets and the guide pieces.
  • a disadvantage of the known tongue lifting device is that the guide piece must be removed together with the rollers in order to adjust the height of the switch tongue or to change the tuning inserts. This is labor intensive and leads to higher costs when adjusting the height of the switch tongue relative to the rail head of the stock rail.
  • the object of the present invention is to provide a tongue lifting device of the type mentioned, in which the height adjustment of the roller and thus the adjustment of the height of the switch tongue relative to Rail head of the stock rail is simple and can be carried out with little labor and cost.
  • the above-mentioned object is achieved according to the invention in a tongue lifting device of the type mentioned at the outset in that the adjusting disc is rotatably arranged on the bearing block in such a way that a rotation of the adjusting disc brings about a height adjustment of the roller carriage.
  • the invention offers the essential advantage that it is no longer necessary to remove the roller carriage in order to adjust the height of the roller carriage or to adjust the height of the switch tongue during the adjustment process.
  • the height adjustment of the roller carriage is brought about by the rotation of at least one adjusting disc. This makes it possible in a simple manner to compensate for tolerances both in the switch tongue and in the stock rail and to adapt the tongue lifting device to different stock rail cross sections.
  • the tongue lifting device according to the invention is characterized in that only a small force has to be used to turn the adjusting disk, which additionally facilitates the height adjustment of the roller carriage.
  • the adjusting disk is arranged on the bearing block so as to be displaceable in the longitudinal direction relative to the stock rail such that a longitudinal displacement of the adjusting disk causes a height adjustment of the roller slide.
  • a particularly simple embodiment of the tongue lifting device provides that at least two mutually adjustable Disks are arranged one above the other in such a way that an adjustment of the adjusting disks brings about a height adjustment of the roller carriage.
  • the mutually adjustable adjusting disks cooperate, wherein in the installed state of the tongue lifting device, preferably adjusting surfaces of the adjusting discs point to one another, with, more preferably, a positioning surface of at least one step of a first adjusting plate resting on a positioning surface of at least one step of a further adjusting plate.
  • the switch tongue it is preferably pulled onto the rollers by motor and rests on the roller in the further course of the adjustment movement.
  • a first adjusting disk preferably serves as an abutment for the second of the two adjusting disks, which are adjustable relative to one another.
  • each individual roller according to the invention in a height-adjustable manner.
  • This offers the essential advantage that the rollers of the tongue lifting device adjacent to the jaw rail can be set at a lower height than the rollers which are arranged away from the jaw rail, without the roller carriage having to be removed.
  • the lower adjusting disk has a slight inclination in the area of its footprint in the direction of the floor rail or is itself arranged at a corresponding inclination.
  • the adjusting disc has a wedge-shaped thickness profile and / or a step-shaped thickness profile with at least two steps with different step heights. Each step corresponds to a fixed height adjustment of the roller carriage. It is basically the case that - if only one adjusting disc is provided for the height adjustment of the roller carriage - a wedge-shaped thickness profile of the adjusting disc can also be provided in order to enable height adjustment of the roller carriage. In the case of a step-shaped thickness profile of the adjusting disc, it is important that the number of steps, over the footprints of which the weight of the switch tongue or the roller carriage is introduced into the bearing block, is sufficiently large so that the limit of the permissible surface pressure is not exceeded.
  • the adjusting disk preferably has a plurality of step sequences lying next to one another, each with a plurality of steps with different step heights.
  • the step heights of adjacent steps of a step sequence are preferably graded ascending or descending, whereby the gradual lifting or lowering of the roller carriage relative to the bearing block is possible with little effort. It must be taken into account here that with increasing distance between two step heights, the effort required to raise the roller carriage increases from one step to the next.
  • the height difference between two step heights of adjacent steps should therefore be relatively small and preferably in the range from 0.5 to 5 mm, preferably approximately 1 mm.
  • the adjusting disk has identical step sequences, preferably two or three step sequences being provided. It is the case here that at least one step of a first step sequence and at least one further step of at least one further step sequence have the same step height.
  • the weight of the roller slide or switch tongue is therefore distributed over the footprints of several steps of a setting disk, as a result of which the surface pressure of each individual footprint decreases. If the roller carriage is supported on a plurality of shelves, the stability of the roller carriage bearing on the storage go for it.
  • the same purpose also serves that, in the case of a circular adjusting disc, steps with the same step height are arranged symmetrically over the circumference of the adjusting disc.
  • steps with the same step height are arranged symmetrically over the circumference of the adjusting disc.
  • the latter For rotating and / or longitudinally displacing the adjusting disk, the latter has at least one engagement section, the engagement section preferably being provided in the area of a step with a large step height, for example in the area of the step with the largest step height.
  • the engagement section must be arranged so that there is no material breakage of the adjusting disk when adjusting the adjusting disk.
  • the engagement section should therefore be arranged as far as possible in a region of the adjusting disc in which the material thickness of the adjusting disc is particularly large.
  • flanks of the steps of a step sequence are beveled with respect to the vertical, so that run-up slopes result.
  • the step with the greatest step height should preferably have a non-beveled flank.
  • the non-beveled flank can serve, for example, as a stop surface to limit the adjustment path of the adjusting disk.
  • the adjusting disks each have step sequences and / or steps with step heights that are complementary to one another with a preferably minimal height setting of the adjusting disks.
  • the contact surfaces of the mutually complementary steps of the adjusting discs rest on one another, so that essentially the entire cross-sectional area of the adjusting disc serves as a supporting surface for the roller carriage.
  • the engagement sections of the adjusting disks, which are adjustable relative to one another can come to a stop preferably at a minimal height position of the roller carriage.
  • the flanks of the steps can come to abut against each other.
  • the stop is preferred when the adjusting discs are at a minimum height, it is of course also possible to be seen that the engagement sections of the mutually adjustable adjusting disks or the flanks of at least individual steps of the adjusting disks come to abut against one another at the maximum height position of the adjusting disks.
  • the adjusting disks, which are adjustable relative to one another are identical components which rest on one another with their respective positioning surfaces in the installed state.
  • the adjusting disk In order to center the adjusting disk or the adjusting disks which are adjustable relative to one another between the roller carriage and the bearing block, the adjusting disk preferably has a central through-bore for a centering means, for example for an adjusting screw.
  • the roller carriage is preferably clamped in the bearing block or fixed on the bearing block by the centering means.
  • the roller carriage has a recess for receiving the adjusting disk or disks, as a result of which these are fixed or fixed in the roller bed.
  • the recess in the roller carriage exposes an engagement region, preferably when the roller is mounted on the longitudinal side of the roller carriage on the long side of the roller carriage facing away from the roller. If the roller is mounted on the end of the roller carriage, the engagement area preferably points into the threshold area. Via the engagement area, it is possible to access the engagement section of the adjusting disk and to twist or adjust the adjusting disk. It can also be provided that the engagement area limits the permissible travel of the mutually adjustable adjusting discs.
  • the engagement area can be determined by the distance between two stop surfaces of the roller carriage, the engagement section of at least one adjusting disc preferably abutting a stop surface of the roller carriage at a minimum or maximum height position of the roller carriage.
  • the roller carriage it is also possible for the roller carriage to be provided for supporting a plurality of rollers, the switch tongue preferably resting on a roller plane defined by the rollers during the adjustment.
  • a plurality of adjusting disks can be provided in order to incline the rolling plane in the direction of the horizontal. This makes it easier to roll the switch onto the roller level.
  • An inclination of the roller plane of the rollers can also be brought about by the formation of the adjusting disc as such, the adjusting disc preferably having a wedge-shaped cross-sectional shape and / or being arranged obliquely.
  • At least one damping means preferably a plastic intermediate layer, between the roller carriage and the bearing block for damping vibrations.
  • Overloads of the tongue lifting device, the z. B. caused by gaping tongues, which are no longer correctly resting on the jaw rails or on the tongue supports, can be prevented by disc springs arranged between the roller carriage and the bearing block.
