Definitions

  • the invention relates to a sliding chair for supporting a second rail, such as a switch tongue, which can be adjusted to a first rail such as a stock rail, the sliding chair being releasably fixable on a base plate such as a ribbed plate by means of a spring element which extends on the one hand in a recess in the sliding chair and on the other can be supported on counter bearings extending laterally along the sliding chair and extending from the base plate.
  • a second rail such as a switch tongue
  • a corresponding sliding chair is e.g. can be found in DE 38 11 408 C2.
  • the U-shaped spring element in plan view extends with its side legs in the longitudinal direction of the sliding chair, ie perpendicular to the longitudinal direction of the rails.
  • the extension of the sliding chair is such that the switch tongue is supported on the sliding chair both in its adjacent and in its remote position.
  • an L-shaped spring element is based on a sliding chair, via which a stock rail is held down.
  • a horseshoe-shaped or ring-shaped slotted spring element is provided according to DE 41 12 926 A1.
  • the present invention is based on the problem of developing a sliding chair of the type mentioned at the outset in such a way that it can be designed to be extremely compact, but at the same time it is ensured that the sliding chair can be fixed to a sufficient extent on the base plate and indirectly or directly the first rail such as a stock rail holds down.
  • the problem is essentially solved in that the sliding chair has a continuous opening running in the longitudinal direction of the rail as the recess penetrated by the spring element, a counter bearing being arranged in the area of the opening of the opening running on one side surface of the sliding chair.
  • the teaching according to the invention has the advantage that the spring element no longer has to run in the longitudinal direction of the sliding chair in order to secure it and at the same time hold down the first rail like the stock rail by means of the sliding chair.
  • This in turn means that the sliding chair can be shortened, only a length being required which must ensure that the second rail is securely supported when it abuts the first rail.
  • in the remote position of the second rail it can run outside or largely outside the sliding chair.
  • the sliding chair extends only to a small extent perpendicular to the longitudinal direction of the rail in a ballast bed, so that sleepers running directly next to the sliding chair can be stuffed with conventional measures and machines. If, on the other hand, sliding chairs were used, which in the usual way also supported the second rail in its remote position, problems regarding the stuffing of neighboring sleepers would arise if the sliding chair did not start from one threshold, but ran between two sleepers.
  • the spring element is a rod-shaped, eccentric spring element which, in the tensioned state, is supported on the one hand in the bottom region of the opening and on the other hand on the counter bearings.
  • the counter bearings themselves are preferably each a plate-shaped element which projects vertically upwards from the base and has an opening which is aligned with the opening of the opening in the sliding chair.
  • the sliding chair itself can be supported directly or indirectly on the foot of the first rail with its rail-side end and, with its end facing away from the rail, is in a U-shaped receptacle made of plastic can exist.
  • fastenings for the base run laterally through the opening of the slide chair.
  • the underlay itself is preferably connected to a carrier, which in turn is based on successive sleepers, in particular a normal sleeper such as a concrete sleeper and a hollow sleeper.
  • the fastening elements such as screws penetrate both the base and the carrier in order to connect the documents to the carrier to the required extent.
  • a fastening such as a screw for connecting the base plate to the carrier is preferably provided in the area of each counter bearing alone.
  • the fastenings serve as safeguards for uncontrolled removal of the spring element, which preferably has a curved course in the untensioned state and is provided with bead-like reinforcements both in the middle and in the end region for support on the bottom of the opening or the counter bearing.
  • the spring element can be designed as a polygonal head at least at one end, preferably at each end, in order to rotate and tension or release the spring element in the opening to the required extent.
  • a base plate such as rib plate 10
  • a carrier 12 is fastened to a carrier 12 by means of screws 14 and 16, the carrier 12 being able to extend between two successive sleepers, in particular between a conventional sleeper such as a concrete sleeper and a hollow sleeper.
  • a conventional sleeper such as a concrete sleeper and a hollow sleeper.
  • the carrier 12 has a T-shape in section, the flange 18, on which the rib plate 10 is fastened, extends along the top of a conventional sleeper or which can be welded to a hollow sleeper, within which a switch lock can be arranged .
  • the carrier 12 is preferably designed such that there is a deflection in the region of the rib plate, which corresponds to the deflection of supports which are fastened on conventional sleepers.
  • a first rail in the form of a stock rail 20 is fastened, which rests with its foot 22 on one side against stops 24, 26 and is held down by tensioning brackets (not shown).
  • the foot 22 is held down by means of a sliding chair 28, the fixing of which is described in more detail below.
  • the rib plate 10 has a T-shape in plan view, the cross leg 30 being penetrated at the end by the screws 14 and 16 in order to fix the rib plate 10 on the flange 18 of the carrier 10.
  • the ribbed plate 10 is vulcanized into an elastic intermediate layer 32, which acts as the first spring element.
  • the intermediate layer 32 should have a linear characteristic, i.e. Force and travel should be proportional to each other.
  • a second spring element which in the exemplary embodiment is designed as rib-like projections 34, 36, 40, 42, each of which has a cap 44, 46 or recesses 35, 38, 41, 42 present in it in the manner described below Way to be included.
  • the characteristic curve of the second spring element formed from the rib-like sections 34, 36, 40 and 42 has a flatter course in the non-prestressed state than the first spring element formed by the intermediate layer 32.
  • the second spring element formed by the rib-like sections 34, 36, 40, 42 and thus the rib plate 10 is pretensioned relative to the carrier 12 in such a way that there is an overall course consisting of the flat section and a steeply rising section results.
  • This steeply rising section is achieved in that the sections 34, 36, 40, 42 are prestressed by means of the caps 44, 46 in such a way that they are compressed on all sides.
  • the rib-like projections 34, 36, 40 and 42 can no longer exert spring properties in the actual sense, so that the steep course results.
  • the caps 44, 46 are tightened by means of the screws 14, 16, so that the recesses 35, 38, 41, 42 present in the caps 44, 46 are full of the rib-like sections 34, 36, 40, 42 fill out.
  • the rib-like sections 34, 36, 40, 42 each have a projection 48, 50, 52, 54, which is dashed in FIG. 4 and has a corresponding depression in the top of the rib-shaped sections 34 in the relaxed state , 36, 40, 42, is assigned.
  • These are also indicated in the figure and have the reference numerals 56, 58, 60 and 62.
  • the recesses 35, 38, 41, 43 in the caps 44, 46 are completely filled and shown by the rib-like sections 34, 36, 40, 42 an approximately rectangular or hat-shaped geometry in section, which is indicated by the hatched area within the cap 44, 46.
  • the intermediate layer 32 as the first spring element and the rib-shaped sections 34, 36, 40, 42 as the second spring element result in an overall spring system which has a kinked characteristic curve in accordance with WO 94/08093, which causes the system to be hard in the static state and dynamic state, ie when the rail 20 is traversed by a vehicle, has soft properties.
  • the sliding chair 28 has an extension perpendicular to the longitudinal axis of the rail 20, which is only slightly longer than the width of a foot 64 of a switch tongue 66, referred to as the second rail, which is adjustable relative to the stock rail 20, that is, it should either rest against the stock rail 20 ( solid representation in Fig. 2) or spaced apart (dashed representation). 2 shows that in the remote position of the switch tongue 66, the switch tongue extends essentially outside the sliding chair 28 and is then supported by roller elements, not shown, which can originate from adjacent sleepers.
  • the sliding chair 28 Due to the short extension of the sliding chair 28 (length transversely to the longitudinal direction of the rail, for example 150 mm and width, for example 120 mm), there is the advantage that the sliding chair 28 does not protrude laterally beyond the carrier 12, so that it is easy to plug adjacent sleepers with conventional tools and Machines is possible.
  • the sliding chair 28 can be securely fixed on the ribbed plate 10 and at the same time holds down the rail foot 22 of the stock rail 20 to the required extent.
  • the sliding chair 28 has a continuous opening 68 which runs in the longitudinal direction of the stock rail 20 and runs parallel to it.
  • a rod-shaped spring element 80 is pushed into the opening 68 via one of the openings 74 and 76 and then rotated in this way by means of at least one tool and thus clamped that the spring element 80 is supported on the one hand on the bottom 82 of the opening 68 and on the other hand on the upper inner surfaces 84, 86 of the counter bearing 74, 76 or the openings 78, 80 of the latter.
  • the spring element 80 is arched in the relaxed state (FIG. 5) and has bead-like reinforcements both in its central region 88 and in its end regions 90, 92, which reinforcements on the one hand on the bottom 82 of the opening 68 or on the upper inner surfaces 84 , 86 of the openings 78) 80 can rest.
  • the spring element 80 In order to be able to rotate and tension the spring element 80, it has polygonal heads 94, 96 at the end, which can be gripped by a tool.
  • the polygonal heads 94, 96 extend between the counter bearings 74 and 76 and the caps 44, 46 when the sliding chair 28 is properly installed. These areas are then covered by caps 100, 102.
  • the sliding chair 28 is positioned in a U-shaped receptacle 104, which can be made of plastic and extends in the longitudinal direction of the stock rail 20. Furthermore, the clear distance between the counter bearings 74, 76, which protrude perpendicularly from the surface of the rib plate 10, is approximately equal to the width of the rib plate 28.
  • the rib plate 10 is supported with its front end on the foot 22 of the stock rail 20 in order to hold it down and thus prevent the stock rail 20 from tipping when a vehicle is being driven through.
  • the sliding chair 28 is secured at the end, that is to say on the side remote from the stock rail 20, by a rib 106 extending in the longitudinal direction of the stock rail 20 and from the rib plate 10.
