Definitions

  • the invention relates to a Schienenisolierformat and a method for cutting a Schienenisolierconcees.
  • the electrically conductive rails are often used as a transmission medium for electrical signals. This is e.g. in track circuits as track detection systems of the case where a section is recognized as occupied, because the rails are electrically short-circuited by the likewise electrically conductive wheelsets and thereby change the electrical properties of the applied track circuits.
  • the electrical conductivity of the rails at the track section interfaces must be interrupted. This is done by separating the rails at the interface and inserting an electrically insulating layer before reassembling the rails.
  • Isolier recital is exposed to high wear due to the different material properties between insulation and rail and the high loads from the overrunning rail vehicles.
  • the wear leads to a deterioration of the mechanical running properties for the rolling wheelsets of the railway cars.
  • bulges may form due to deformation of the edges, which lead to electrical short circuits between the rail sections to be insulated and thus nullify the insulating effect. Attempts have therefore been made to improve by a clever design of Isolierlautes the susceptibility to wear, load capacity and fatigue behavior.
  • DE 1 981 329 U describes a rail for producing an insulating piece, in which the rails have an abutment surface which is inclined at least 30 ° perpendicular to the rail axis and whose longitudinal edges of the abutting surface are injection-molded metal.
  • a rail joint which is designed as a butt joint in the region of the rail head and in the region of the rail web as a butt joint.
  • the oblique impact is perpendicular to the track plane, but formed at an angle between 30 ° and 60 ° to the rail longitudinal direction.
  • the transition region between oblique and butt joint is formed by a recess which is formed as a through hole.
  • the recess is filled by a correspondingly shaped two-part insulating intermediate layer.
  • Object of the present invention is to provide a Isolierction that can withstand the high loads in rail transport better than the insulating joints of the prior art. It is another object of the invention to provide a method for producing such a Isolier warmthes.
  • the Schienenisolierrich invention according to claim 1 comprises adjacent rail ends, which are electrically separated from each other with an electrically insulating intermediate layer.
  • the rail insulation joint is designed as a butt joint in the area of the rail head up to the area of the middle of the rail height and as a butt joint in the rest of the rail web up to and including the rail foot.
  • the transition between oblique and butt joint is continuous.
  • the inventive design of the rail nenisolierfures ensures that there is no gap in the supporting material from the rail head to the rail reaching optimum force removal.
  • the better rolling and wear properties of the oblique joint are optimally timal combined with the advantageous stability characteristics of the butt joint in the region of the rail foot and the rail web, by the transition between the two shock types is designed continuously.
  • the discontinuous force transmission paths leading to crack formation are thus avoided. Due to the continuous transition, the occurring forces can be better distributed in the material and thus optimally absorbed.
  • the continuous rotation of the cutting plane along the cutting path is advantageously realized according to claim 2 in a transition region of +/- 45 mm in the middle of the web.
  • the transition area between oblique and butt joint can thus be up to 90 mm. This avoids an abrupt change in force removal, reducing stress at the interface compared to prior art insulation joints.
  • the angle between the oblique abutment plane in the rail head and the longitudinal direction of the rail is advantageously between 30 ° and 60 ° according to claim 3. This angular range ensures the best mechanical conditions with regard to the wear of the material on the rail head and the rolling comfort for the wheel sets passing through the insulating joint.
  • the inventive method for producing a Schienenisolierhabes according to the aforementioned claims is described in claim 4. Only a non-contact separation device is able to realize the required cutting profile. For this purpose, the separator must begin the separation process at the top or bottom. The separator moves all the time along a line perpendicular to the rail longitudinal direction (separation direction). The speed of cutting is thereby continuously adapted to the material thickness to be separated.
  • the separation device In the transition region between oblique and butt joint, the separation device is moved further in the separation direction, but now the cutting plane is rotated continuously by pivoting the separation beam. If the separator begins at the foot end with the separation process, the parting line for the butt joint initially runs perpendicular to the track level.
  • the separation plane is continuously rotated in the oblique plane by the separation beam is continuously rotated about the axis lying in the direction of separation with progressive separation in the oblique plane.
  • the parting plane At the end of Transition region is the parting plane then rotated in the associated Schrägstumpfwinkel to the rail longitudinal direction.
  • the separation beam begins to separate accordingly in the oblique impact level and is analogously continuously rotated in the transitional area in the butting plane.
  • non-contact separation devices come into consideration, in particular 3D water jet cutting devices, electron beam systems, laser cutting devices or plasma cutting devices.
  • FIG. 1 The upper part of FIG. 1 shows a section through a rail insulation joint according to the invention.
  • the insulating joint is designed as a butt joint (5), in the region of the rail head (1) as an oblique joint (6).
  • the transition area (4) between the two types of impact lies in the area of the tab holes and is up to +/- 45 mm above or below the drill axis height.
  • FIG. 1 shows a plan view of a rail insulation joint according to the invention.
  • Figure 2 Shock interposition of electrically non-conductive material which is introduced between the rail ends of the invention Schienenisolierconcees.
  • Their profile is adapted to the rail profile according to the invention and thus also corresponds to a butt joint in the region of the rail foot and an oblique impact in the region of the rail head.

  • Figure 4 Definition of the descriptive geometric quantities of the embodiment.
  • a UIC 60 rail is to be equipped with an insulating joint according to the invention.
  • the rail is advantageously placed on the side, so that the rail foot plane thereby stands in the vertical (10).
  • the cutting jet can be passed into a water basin during the separation process.
  • the separation process could also be carried out at any other storage of the rail.
  • the line running in the middle of the rail web perpendicular to the rail longitudinal axis between the rail foot and the rail head is defined as the separating direction line (1 1).
  • the cutting jet (15) always leaves the cutting head tip aligned with the separating direction line (1 1).

  • the speed of cutting is continuously adjusted.
  • the water jet is now brought in the parting plane at an insertion angle ⁇ of about 30 ° to 60 ° (12) to the rail base (3) and begins at the lower edge of the rail foot with the separation.
  • the parting plane is determined by the separating direction line (1 1) and the vertical (10).
