Definitions

  • the invention relates to box sleepers in a closed construction for switch devices, in which electrical heating elements are arranged, as by DE-A-43 15 200 known.
  • the previously used box sleepers - which for better darning by means Switch tamping machines and improved settlement behavior are the same Box cross-sections such as wooden or concrete sleepers have - to the Reduce production costs, from relatively thin folded sheets to U-profiles formed, on the two flanges of which the upper chords are welded. To the cost to keep consciously low, the entire cross section of the box sleeper is disregarded after the welding process to glow with low stress, which is a brings increased cracking and corrosion.
  • the heat transfer is the Heating rods on the entire box threshold very bad because the heating rod with only two fastening clamps on the - bulged by the ballast and thereby wavy - floor plate is mounted.
  • the heating element cross section is often in a water accumulation area so that premature corrosion and thereby a possible defect, e.g. a short circuit is preprogrammed.
  • the invention is based, with a generic box threshold the task the arrangement or accommodation of the box sleeper heating improve, in particular the availability of the switch and operational safety increase.
  • the box threshold is formed at least with an inlet opening for heating element feed lines in such a way that the heating rod can be replaced through this opening.
  • the entrance opening is located preferably in one of the two longitudinal walls of the box sleeper and is 60 ° in Inclined towards the front wall of the box sleeper. This allows the Heating rod feed lines - there are usually two heating rods for one box threshold - with a relatively small amount of buckling together through the entrance opening in the Introduce box threshold.
  • the entrance openings are chosen so large that one of the two supply cables Receiving angled cable protection tube, which is preferably made of plastic exists, can be inserted inside the box threshold. With that they are Supply cable on the one hand in the area of the entrance opening and on the other hand outside the box sleeper effectively protected against damage in the area of the ballast.
  • a is in the interior of the box threshold Cable protection tube arranged.
  • a supply cable becomes that of the selected one Inlet opening on the closest heating element is fed directly while the other supply cables through the inner protective tube to the from the Heating rod removed from the inlet opening.
  • the cable protection tube Base bars rests and is held by means of clamping springs.
  • the plinths are in the right-angled transition area between the longitudinal wall and the floor of the Box threshold arranged. Are over the entire length of the box threshold
  • Tension springs arranged between two base bars, which are in the sleeper floor trained openings protrude and on a web delimiting the opening of the sleeper floor are fixed.
  • the cable protection tube is through easy to push in between the clamping spring and base bars locked, on the other hand the clamped cable protection tube lies on the baseboards, so that any water on the sleeper floor is not in the Protective tube can penetrate.
  • end stops are advantageously assigned to the cable protection tube, between which the cable protection tube is embedded immovably axially; thereby a pinching of the cable between the front sides of the box threshold and the Cable protection tube effectively prevented.
  • a preferred embodiment of the invention provides that the heating elements on a Spacer bar arranged and locked there by means of tension springs.
  • the spacer bar is in the longitudinal axis of the box sleeper on the box sleeper floor arranged; on it lie the two arranged one after the other on one level Heating rods on.
  • the preferably S-shaped tension springs are each on a raised base.
  • the upper clamps overlap the heating rods and fix them on the spacer bar.
  • the lower clamp of the Tension spring protrudes into a turnstile which is also formed in the sleeper floor Opening and is on a web of the raised base and delimiting the opening of the sleeper floor fixed securely.
  • the heating rods are several on the Bottom rail assigned stops arranged.
  • Another embodiment of the invention provides that the heating rod heads on a Place the skirting board and fasten it with a spring clip.
  • the Skirting board is between the vertical longitudinal walls of the box threshold on the Box sleeper floor arranged.
  • the heating rod heads are with an overlapping double-lobed clamp or one made of spring steel Band resiliently screwed against the skirting board. Thanks to the resilient screw connection the heating rod heads will be safely grounded if they are no longer intact Heating rod insulation guaranteed.
  • the heating element heads are also on the side Stop assigned to when screwing the double-lobed clamp or Spring band to prevent the heating rod head from slipping.
  • the heating elements or the heating element heads on the Box sleeper floor and the associated full-surface support results on the one hand, good heat transfer to the floor area of the box sleeper.
  • the heating elements used up to now with an individual heating output of Exchange 2x450W for heating elements with a single heating output of 200-300W which has a very big economic advantage.
  • the Heating elements are not - as is usual with known arrangements - in the water collection area the box threshold, which effectively corrodes the heating rods is prevented.
  • the sleeper floor is gutter-like trained and provided with at least one water drain opening.
  • Under Channel-like formation of the floor are both in the longitudinal and in the transverse direction Floor surfaces inclined towards the water drainage opening that understand the water direct the process to the lowest point.
