Definitions

  • the present invention relates to an anchor for a sleeper embedded in ballast of a track system, with an attached to the sleeper, which essentially wraps transversely to its sleeper axis in the area of the sleeper top and the sleeper side surfaces, approximately U-shaped bracket, at the ends of which a essentially in a vertical plane, transversely and / or parallel to the threshold axis and protruding into the ballast plate to increase the transverse displacement resistance and / or the longitudinal displacement resistance of the track system is attached.
  • anchors of the type described above can be easily installed on the ballast bed without any significant exposure work (cf. DE-PS 31 07 990). For this it is only necessary to push the U-shaped bracket with its opening side onto the sill approximately transversely to the sill axis under the action of force from top to bottom in such a way that the plates dig into the ballast bed in front of and behind the sill, possibly using vibrations.
  • Anchors of this type can be arranged at any point on the threshold, ie also in the middle of the threshold are, so that the already heavily loaded ballast bed in the area of the sleeper heads is relieved and possibly saved on wide gravel belts in front of the sleeper heads.
  • the object of the present invention is now to develop an anchor of the type described in such a way that the assembly, in particular with regard to the problems described above, is further simplified.
  • the clip is formed in two or more parts and the clip parts are connected to each other in the assembled state.
  • An anchor is created for the first time by the features according to the invention, in which the plates are no longer together and in particular simultaneously, i.e. must be driven into the ballast bed synchronously, but independently of each other, i.e. can be driven into the ballast bed one after the other or at least alternately one after the other. This considerably simplifies and simplifies assembly.
  • the plates and the clamp parts are in the predetermined position, they can be fastened to the threshold in any way, for example by screws or the like.
  • the clip halves can be shaped in any way. However, it is advantageous if an essentially L-shaped shape is selected which is curved in the area of the upper side of the threshold.
  • the clip halves are made of spring steel.
  • the joint arrangement can in principle be designed in a wide variety of ways. According to an advantageous development, it is expedient to design the joint arrangement as a hinge with a hinge axis running parallel to the threshold axis.
  • the joint arrangement is particularly advantageous to design the joint arrangement as a coupling arrangement with which the ends of the two clamp halves can be coupled to one another in a tensile manner, but can be pivoted relative to one another within limits about an axis running approximately parallel to the threshold axis.
  • Such a coupling arrangement can be integrated into the ends of the two clip halves as well as include additional parts.
  • the coupling arrangement has a separate coupling piece which has an upwardly open receiving channel which receives the overlapping ends of the clamp halves.
  • the coupling piece is equipped with a vertically oriented sleeve, which is fastened with its lower end in a bore of the coupling piece, preferably welded, and with its free end protrudes through elongated holes aligned in the overlapping ends of the clip halves.
  • the overlapping ends of the clamp halves are guided laterally in the receiving channel, the elongated holes ensuring the required mobility on the sleeve.
  • the ends of the clip halves are connected to one another in a tensile manner, on the other hand, however, it ensures that the required articulation is given at the connection point.
  • the clamping means can basically be designed in any manner.
  • wedge or screw arrangements are particularly simple and expedient clamping means. It is essential with such wedge or screw arrangements that they are supported on the one hand on the upper side of the threshold and on the other hand on the joint arrangement of the armature.
  • a screw bolt is chosen as the clamping means, which is arranged in an internal thread of the bore of the sleeve and is supported with its free lower end via a pressure plate on the top of the threshold.
  • the clamping force can be continuously adjusted by appropriately designing the clamping device.
  • Anchors of the type according to the invention are therefore suitable both for use on wooden sleepers and for use on concrete sleepers.
  • Anchors of the type according to the invention can also be used again after a long period of inactivity or storage. It is only necessary to prevent corrosion by selecting the appropriate material or using suitable surface protection.
  • tie anchor of the type according to the invention need not be removed the. It is only necessary to loosen the clamping device and restore the tension again after working through. This work can be carried out without difficulty when using clamping devices in the form of screw arrangements with conventional screwing machines.
  • ballast bed remains completely intact when anchors of the type according to the invention are installed, the desired increase in the transverse or longitudinal displacement resistance is immediately present in full after installation.
  • each plate can be shaped in many different ways. A particularly advantageous effect results, however, if the lower edge of each plate is essentially rectilinear and in each case forms an angle with the associated side surface of the threshold that is less than 90 °, preferably in the range between 60 ° and 80 °.
  • the lower edge of each plate is essentially rectilinear and in each case forms an angle with the associated side surface of the threshold that is less than 90 °, preferably in the range between 60 ° and 80 °.
  • each plate is also substantially rectilinear and inclined in such a way that it encloses an angle with the associated side surface of the threshold which is less than 90 ° and preferably between 60 ° and 80 °. This measure also ensures that the plate when one driving process maintains contact with the threshold, since the inclination of the upper edge by means of a driving tool placed on the upper edge provides not only a component running in the vertical direction but also a component directed towards the threshold side surface.
  • each plate consists of two essentially rectilinear sections, the first section adjoining the respective clamp half being at an angle of 60 ° to 80 ° with respect to the associated side surface of the threshold and the adjoining second section an angle of between 30 ° and 40 °. It is usually sufficient if the driving tool acts on the first section. However, if the clamp or the projection provided for it does not sufficiently reach under the threshold due to the unfavorable position of the ballast in the ballast bed, it is only necessary to convert the driving tool to the second section and to exert a driving force on the plate again. Due to the relatively acute angle between 30 ° and 40 ° relative to the assigned side surface of the threshold, the plate will easily assume the predetermined position in such a case.
  • the plates can be aligned parallel to the threshold axis to increase the transverse displacement resistance transversely to the sleeper axis or to increase the longitudinal displacement resistance of the track system. According to an advantageous further development, however, it is also possible to assemble a plate from plate sections oriented parallel and transversely to the threshold axis and in this way to contribute with one and the same plate both to increase the transverse displacement resistance and to increase the longitudinal displacement resistance of a track system.
  • the anchors shown in the figures consist of an approximately U-shaped bracket 4, which surrounds a sleeper 1 essentially transversely to its axis in the area of the sleeper top 2 and the sleeper side surfaces 3, at the ends of which plates 5 are fastened.
  • the U-shaped clamp 4 is designed in two parts according to the invention, the clamp parts 6 and 7 being approximately the same size to form clamp halves.
  • connection of the clamp halves 6 and 7 is also designed as a joint arrangement 8 and in the region of the joint arrangement a tensioning means 9 is provided for generating a clamping force which clamps the clamp halves on the threshold.
  • the threshold 4 is gripped under the threshold on both sides.
  • support surfaces 10 are provided in both embodiments, which in the case of the exemplary embodiment according to FIG. 1 are integrated into the clip ends or the plates and, in the case of the exemplary embodiment according to FIGS. 3 and 4, are formed by support angles which are welded to the plates 5.
  • the clip halves 6 and 7 are bent approximately L-shaped and made of spring steel.
  • the joint arrangement 8 is designed as a hinge 11 with a hinge axis 12 running parallel to the threshold axis.
  • the joint arrangement 8 is designed in the manner of a coupling arrangement with which the ends of the two clamp halves 6 and 7 are connected to one another in a tensile manner. Due to the special design, which will be described in the following, the two ends can, however, be pivoted against each other within limits about an axis running approximately parallel to the threshold axis, so that the coupling to one another also takes place in an articulated manner in this exemplary embodiment.
  • the coupling arrangement for the ends of the two clamp halves 6 and 7 in the embodiment shown in FIGS. 3 and 4 comprises a coupling piece 13 which, as can be seen in particular from FIG. 5, consists of a piece of commercially available U-profile.
  • the coupling piece 13 has an upwardly open receiving channel 14 in which the overlapping ends of the clamp halves 6 and 7 are mounted.
  • the coupling piece 13 is provided in its bottom area with a bore in which a vertically oriented sleeve 15 - preferably by welding - is attached.
  • the sleeve 15 is dimensioned such that it protrudes slightly upwards over the coupling piece 13.
  • the ends of the two clip halves are provided with elongated holes 16 and 17, through which the sleeve 15 protrudes.
  • the sleeve 15 is equipped in its bore with an internal thread that carries a screw bolt 18, which is supported with its free lower end via a pressure plate 19 on the top of the threshold 1.
  • the shape of the plates 5 is essentially trapezoidal in the embodiment shown in FIGS. 3 to 5.
  • the lower edge 20 of each plate is formed in a straight line and aligned obliquely such that it encloses an angle of approximately 75 ° with the associated side surface of the threshold.
  • each plate 5 is in turn composed of two substantially straight sections.
  • the first section 21 adjoining the respective clamp half is inclined in such a way that it encloses an angle of approximately 80 ° with the associated side surface of the threshold.
  • the second section 22 adjoining this first section 21 is in turn inclined such that it encloses an angle of approximately 40 ° with the associated side surface.
  • the plates 5 are driven either jointly or, after pulling the hinge pin one after the other, into the ballast bed via the clamp halves 6 or 7 via a device.
  • the wedge is driven between the top 2 of the threshold and the hinge 11, as shown in FIG. 1.
  • the hinge is raised relative to the upper side of the threshold so that the support surfaces 10 come into firm contact with the lower side of the threshold and dig into it slightly.
  • the shape of the clamp halves and the height of the wedge is dimensioned such that a clamping force previously defined in temptation is generated.
  • the curved design of the spring halves 6 and 7 made of spring steel ensures that the predetermined tension is maintained even when the wedge is slightly worked into the top or the support surfaces into the bottom of the threshold during operation.
  • the wedge has a so-called latching step. This ensures that on the one hand the wedge can only be driven under the joint arrangement up to a certain amount, on the other hand it can no longer slide out of its final position when shaken.
  • a driving tool is placed on the first section 21 of the plate 5. Due to the inclination of the first section 21, a component directed towards the threshold always acts on the plate during the driving-in process, so that the plate always remains in contact with the side surface 3 of the threshold during this process. This effect is reinforced by the inclination of the lower edge 20 of the plate 5, so that even with difficult ballast bed conditions it is ensured that the support surface 10 in the form of the holding bracket engages under the underside of the threshold in the final position.
  • the plate 5 does not yet have the required position close to the threshold in the lowered state, it is only necessary to convert the driving tool from the first section 21 to the second section 22. Due to the inclination of the second section 22, a force can then be exerted on the plate 5, which in any case ensures that the mounting bracket engages under the threshold in the desired manner.
  • the coupling piece 13 is threaded with the sleeve 15 into the L. gloch 16 and then the opposite plate 5 with the bracket half 7 in the ballast bed in the manner shown above driven until the slot 17 of the clamp half 7 is also penetrated by the bush 15 of the coupling piece 13.
  • the upper end face of the sleeve 15 serves as a voltage limiter. As soon as the hexagon head of the bolt 18 lies against the upper end face, further rotation of the bolt and thus an increase in the clamping force is no longer possible.
  • the shape of the clip halves and the plates can be designed in a wide variety of ways. According to the invention, it is only necessary to form the clip in two or more parts, so that the anchor can be driven in the untensioned state. According to the invention, the clamping force required for fastening to the threshold is then to be applied only in the final position of the anchor.
