Definitions

  • the invention relates to a railroad track switch device comprising a stock rail, a switching rail that merges into a control rail such as a channel rail, a guide rail, a retainer that holds the switching rail on the control rail side in a force-fit, in particular by means of a wedge element, and a slide device, such as a slide plate, that slidably supports the switching rail.
  • a corresponding railroad track switch device is known from EP 0 603 883 B1.
  • the guide or secondary rail may consist of flat stock.
  • the retainer which can also be described as a switch adapter, for the switching rail accommodates the switching rail by sections and secures it, in particular, by a double wedge clamping plate.
  • the switch adapter itself sectionally limits a channel merging into the connecting rail.
  • a railroad track switch device is known from DE 199 20 858 A1 in which the guide rail and support bed for the switching rail are made as one piece.
  • a foundation block may be produced by casting and may be given the desired geometry by machining.
  • the switch adapter itself can thereby also be formed from the block.
  • This is associated with structural and production-related disadvantages which are caused by the use of a massive component.
  • massive rectangular sections do not have a defined rolling structure due to their low degree of shaping, so that gas bubbles and shrink holes may be present in the block interior which can permeate the surface during finishing, as a result of which the function of the component is affected.
  • Massive rectangular sections also have worse material properties and mechanical properties in comparison to individual rolled components. Since there is basically no homogeneous structure, the slight fissure elongation promotes the tendency to crack formation.
  • EP 013 826 A1 relates to a switching rail which has a geometric shape on the connecting rail side that corresponds to the connecting rail. To this end, there is a partial reforging of the end section of the switching rail on the rail side.
  • a switching device in monoblock form is known from DE 808 713 C.
  • the present invention is based on the problem of further developing a railroad track switch device of the aforementioned type, as well as a method for the manufacture thereof, such that only a few components must be used for manufacturing the device without forfeiting any functional efficiency.
  • good material properties are to be provided and they should not change, or not substantially change, during a necessary machining.
  • materials are to used which exhibit optimum suitability for a railroad track switch device. A simplified production should also be made possible.
  • the problem is essentially solved in that the guide rail is a machined section of a rolled section consisting, in particular, of a rail-steel, which has on the control rail side a cross-section that corresponds to the control rail and seamlessly merges into the latter.
  • the rolled section is a structural rail such as a thick web rail or a filled section rail or a rectangular rail having e.g. a cross section of 180 ⁇ 180 mm 2 .
  • a rolled section such as a structural rail
  • the guide rail which has good material properties and high mechanical quality values, as is known for rail steel.
  • rail steel proven weld constructions are maintained, so that all elements can be made with materials best suited for their function.
  • a rolled sheet of a wear-resistant type of steel can be used for the slide device, such as a slide plate, a possibility that is not possible when building the railroad track switch device in a monoblock manner.
  • a more economical production is obtained, in comparison to monoblock constructions, since the processing cost, such as the machining cost, is kept within bounds.
  • the retainer such as a switch adapter, receiving the end of the switching rail on the control rail side is welded with the machined rolled section such as the machined structural rail. Consequently, there is an apparent monoblock construction in the area of the connection of the switching rail with the adapter, so that the advantages existing in this respect are assumed.
  • the retainer is a reforged section of the rolled section. It is also possible to connect a separately produced retainer to the machined rolled section fixedly, e.g. by a screw connection.
  • the alignment of the retainer, on the one hand, to the machined rolled section and, on the other hand, to the section of the switching rail receiving the retainer is such that the channel extending in the area of the retainer and continuing in the control rail is only limited by the machined rolled section and the section of the switching rail.
  • a further embodiment of the invention provides that the rolled section, in the form of a structural rail has before the retainer, as viewed from the switch rail tip, a course which is displaced is compared to the course in and beyond the retainer.
  • the railroad track switch device according to the invention has a structure which has the advantages of a monoblock construction without assuming the disadvantages thereof. In this case, appropriate materials can be used which satisfy an optimum functional efficiency without having to accept any production-related disadvantages.
  • the guide rail is made from one component, that is machined to the required degree, over the entire length of the switching rail up to the control rail.
  • a method for forming a section of a railroad track switch device comprising a stock rail, a switching rail that merges into a control rail such as a channel rail, a guide rail, a retainer that holds the switching rail as well as a slide device that slidably supports the switching rail between the stock rail and the guide rail is characterized in that the guide rail is made from a rolled section consisting of a rail steel by machining and changes into a section having a cross-sectional shape which corresponds to the control rail and which is formed by machining of a section of the rolled section.
  • the rolled section can be bent prior to this processing, in particular the machining, thereof.
  • the rolled section receives its basic contour prior to the machining by e.g. autogenous gas cutting.
  • the rolled section can be connected, e.g. by welding, with the retainer after the machining and the rolled section can then be bent to obtain the desired shape.
  • FIG. 1 a shows a plan view of a railroad track switch device
  • FIG. 1 b shows a section of the device according to FIG. 1 a, insofar as it relates to the guide rail,
  • FIG. 2 shows a section along the line A-A in FIG. 1 a
  • FIG. 3 shows a section along the line B-B in FIG. 1 a
  • FIG. 4 shows a section along the line C-C in FIG. 1 a
  • FIG. 5 shows a section along the line D-D in FIG. 1 a
  • FIG. 6 shows a perspective illustration of a section of an arrangement corresponding in principle to the railroad track switch device of FIG. 1,
  • FIG. 7 shows an alternative design of the guide rail in FIG. 1 b in the area of a switch adapter
  • FIG. 8 shows a perspective illustration of a section of a railroad track switch device.
  • FIGS. 1 a and 1 b Essential elements of a railroad track switch device having a basically known construction can be seen in FIGS. 1 a and 1 b in a plan view.
  • the railroad track switch device comprises a guide rail 10 and a stock rail 12 and a switching rail 14 which can be slidably adjusted on a sliding plate 16 .
  • Conventional control devices (not described in greater detail) can be used to adjust the switching rail 14 .
  • the switching rail 14 is fixed in a retainer 18 on the root side, i.e. secured in the retainer 18 by means of a wedge element 20 as per FIG. 4, as described by way of example in EP 603 883 B1.
  • the rail sections adjoin control rails such as channel rails which can be joined in the conventional manner by welding with the rail sections.
  • the guide rail 10 in the entire railroad track switch device up to the end 22 at the control rail side is a section of a rolled section, in particular, in the form of a structural rail such as a thick web rail 24 , which is given the desired cross-sectional shape by machining.
  • a rolled rail-steel section is used as starting material, which is given the desired geometric shape inside the railroad track switch device, in particular by machining, in order to form the guide rail 10 on the one hand and, on the other hand, to receive a cross-sectional shape on the control rail side which corresponds to that of the control rail.
  • This cross-sectional shape is identified by reference numeral 26 in FIG. 1 b.
  • the rolled section 24 Prior to machining the rolled section 24 , which will simply be called a structural rail in the following, it can be bent to the required degree, i.e. such that an outward bend results directly in front of the retainer 18 for the switching rail 14 , also called switch adapter, as can be seen in FIG. 1 b, or can obtain a desired contour shape as shown in FIGS. 7 and 8 by e.g. cutting a corresponding profile.
  • FIG. 1 b The shape of the structural rail 24 relative to its web 28 , on the one hand, and, on the other hand, to what degree it must be machined to obtain the desired end geometry along the switching device can be seen in FIG. 1 b and in a comparison of FIG. 2 to FIG. 5. It is also especially clear from the basic illustration of FIG. 5 and the right sectional illustration in FIG. 1 b that there is a geometry in the end area on the control rail side which corresponds to the control rail to be welded to the joint abutment 22 .
  • the guide rail 10 has steps, which are not identified in greater detail, on which the slide plate 16 can be supported, which can be joined, particularly by welding, to the guide rail 10 and the stock rail 12 .
  • the slide plate 16 can essentially consist of smaller and larger slide plate sections 30 , 32 , 34 , as shown in FIG. 6.
  • the switch adapter 18 itself is welded to the structural rail 24 (FIG. 4) and holds the switching rail 14 in its end on the control rail side, i.e. root side, in a clamping manner, as already mentioned, especially by wedge clamping plates 20 .
  • the channel 36 extending in this area and continuing in the control rail is thereby defined as follows.
  • Channel flanks 38 on the one hand, and travel flanks 40 of the channel 36 , on the other hand, are formed by sections of the structural rail 24 or the switching rail 14 .
  • the channel base 42 of the channel 36 is also a section of the structural rail 24 , so that the switch adapter 18 itself does not directly limit the channel 36 . Rather, the switch adapter 18 extends along the base 42 and the outer side 44 of the switching rail 14 facing away from the channel and is welded to the web 28 of the structural rail 24 on the one hand and to the foot 46 on the other hand.
  • machined structural rail 24 extends to both sides of the switch adapter 18 , seen in longitudinal direction.
  • a thick web rail (Type D 180/105) is especially suitable as structural section.
  • Other structural rails such as filled line end rails, filled section rails or the like are also suitable.
  • a rectangular rolled rail-steel section having an edge length XY of e.g. 180 ⁇ 180 mm 2 was used as structural section to carry out the teaching of the invention in FIGS. 7 and 8. Independently thereof, the same reference numbers are used for the same elements in the embodiments of FIGS. 1 to 6 .
  • the contour and the shape of the guide rail 10 as well as the area in which the switch block 18 is connected, e.g. welded, to the structural section, as well as the area 50 corresponding to the cross-section 26 of a channel rail at the control rail side is produced by e.g. autogenous gas cutting of the initial section 124 or by similar methods and subsequent machining.
  • FIG. 7 This can also be seen in the perspective illustration of FIG. 8, in which slide plate sections 32 , 34 , as in FIG. 6, are also shown.
  • the switching rail 14 merges at the oblique joint into the travel head 48 of the end section 50 of the rolled section 124 , the cross-section 26 of which corresponds to the control rail. Consequently, the section 26 has the travel head 48 , the channel head 52 as well as the channel 54 extending between them, which merges into the channel 36 , as is shown in FIG. 4.
