Definitions

  • the invention relates to a rail pulling device for the longitudinal displacement of rails of laid rails with two transverse yokes running at right angles to the longitudinal direction of the rail, and with transverse yokes each pivotably mounted on a transverse yoke, each forming a pair spaced apart in the longitudinal direction of the rail, with clamping jaws provided for contact with the rail, whereby the two pairs of clamping pliers running parallel to one another are connected to one another by hydraulic drives.
  • a known from GB-PS 1 294 216 rail pulling device of this type is designed as an annular structural unit and has two clamping pliers spaced apart from one another in the transverse direction of the rail, each of which is rotatably connected to one another about vertical pivot axes by a holding member or transverse yoke arranged above and below the rail.
  • the clamping jaws for contacting the rail web are connected via short levers which act like a toggle lever to hydraulic drives running in the longitudinal direction of the rail and to tension members running in the longitudinal direction thereof.
  • EP-A2 o 132 227 is a device for aligning and butt welding two rail ends known.
  • This device consists of a rigid frame, which is formed from two parallel longitudinal rails running in the longitudinal direction of the rails, which in turn are rigidly connected to one another by four cross struts.
  • boxes are arranged both above and below this frame, which can be moved relative to one another by corresponding hydraulic cylinders.
  • a cylinder running transverse to the longitudinal direction of the rail presses the two jaws against the rail web.
  • Each of the lower boxes has a longitudinally displaceable device for deburring the weld seam.
  • This known device is structurally particularly complex and complicated due to the rigid frame and the numerous hydraulic cylinders and longitudinal guides.
  • DE-OS 38 35 758 describes a further rail pulling device of the generic type, the two hydraulic drives running in the longitudinal direction of the rail and the two pairs of clamping pliers being so far apart that a flash butt welding device can be inserted into the annular unit of the rail pulling device. In this way, even relatively heavy rails with larger gaps can be welded together using the flash butt welding unit and the rail pulling device.
  • the invention has for its object to provide a rail pulling device of the generic type for applying very high tensile forces, the two rail ends to be welded to one another being easily centered on one another for the unrestricted simultaneous use of a flash butt welding unit.
  • each pair of clamping pliers an at least two hydraulic cylinders which can be acted upon independently of one another is connected to the cross-yoke by means of rail-centering devices provided for contact with the rail and / or threshold.
  • rail-centering devices provided for contact with the rail and / or threshold.
  • a further embodiment of the invention is that the rail centering device has two hydraulic cylinders running perpendicular to the longitudinal direction of the hydraulic drives or to the longitudinal direction of the rail and horizontally opposite one another with respect to the plane of rail symmetry, and two further hydraulic cylinders running parallel to the pivot axis of the clamping tongs. With these four hydraulic cylinders, the rail end can be precisely centered in terms of both sides and height with minimal design effort.
  • the vertical hydraulic cylinders each have at their free, lower piston-side ends as a pressure ram a support roller with a horizontal and transverse to the longitudinal direction of the hydraulic drives or the rail Axis of rotation, the entire centering device together with the rail end can be distanced from the sleepers for height centering.
  • the support rollers By using the support rollers, an unhindered longitudinal displacement of the pairs of clamping pliers can be carried out while maintaining the height centering in order to reduce the rail joint gap.
  • a holder connected to the piston of the vertical hydraulic cylinder and supporting the support roller is designed for height-displaceable contact with a guide rib running in the longitudinal direction of the hydraulic cylinder with a guide plane running transversely to the longitudinal direction of the rail.
  • a further embodiment of the invention consists in the fact that the rail centering device has a hydraulic cylinder that runs parallel to the pivot axis of the clamping tongs and is provided for contact with the rail head and runs symmetrically to the plane of symmetry of the rail. With this vertical hydraulic cylinder, the rail end can be bent in the vertical rail symmetry plane towards the sleepers with a minimum of design effort.
  • the hydraulic cylinders of the rail centering device are fastened on a support plate which is connected directly above the clamping jaws to the transverse yoke and projects to the opposite pair of clamping pliers and which has stiffening ribs running in the longitudinal direction of the rail.
  • this is a simple and stable fixation of the rail centering device on the rail pulling device and, on the other hand, an easy to carry out fastening of the hydraulic cylinders possible without the function of the clamping pliers located in the immediate vicinity being impaired.
  • the transverse yoke is connected in the area opposite the rail centering device to a U-shaped support member provided for resting on the rail head.
  • stops are provided on the underside of the transverse yoke to limit the opening movement of the clamping pliers. This ensures that when the hydraulic drives are acted upon, the two clamping tongs lying opposite one another in the transverse direction are opened symmetrically, which means that the rail pulling device can be easily lifted off the two rail ends.
  • An advantageous development of the invention also consists in that the two transverse yokes spaced apart from one another in the area of the hydraulic drives connecting the pairs of clamping pliers to one another by parallel to these extending positioning drives are interconnected.
  • Such positioning devices advantageously enable a corresponding opening of the pairs of clamping pliers by correspondingly changing the distance between the two transverse yokes, without having to act on the heavy hydraulic drives for this purpose.
  • the positioning devices also ensure that the distance between the two transverse yokes is not changed by the hydraulic drives when the clamping pliers are opened.
  • the clamping tongs are connected to each other by two hydraulic drives arranged parallel to each other, each of the four hydraulic drives of the rail pulling device with their longitudinal axes being arranged in a common plane running perpendicular to the pivot axes of the clamping tongs, in which also the System on the rail web provided jaws are arranged symmetrically with respect to their height.
  • Such a construction of four hydraulic drives connecting the two pairs of clamping pliers to one another enables - due to the cylinder diameter that can be reduced without reducing the tensile force - their arrangement in a plane running perpendicular to the pivot axes and identical to the plane of symmetry of the clamping jaws, so that in a particularly advantageous manner the clamping pliers can be arranged in a single plane running perpendicular to the swivel axes and centering in relation to the rail height. In contrast to a cranked design of the clamping pliers, this reliably prevents the formation of bending moments.
  • each pivotable Clamping pliers in the longitudinal direction of the rail pulling device in the area before and after the pivot axis each have a clamping jaw that can be placed on the rail web or a corresponding fastening device for optionally arranging a clamping jaw.
  • a welding machine 1 with a bridge-shaped machine frame 2 can be moved by rail carriages 3 arranged at the ends on a track 6 having rails 4 and sleepers 5 with the aid of a travel drive 7.
  • a central energy unit 8 with a drive motor, hydraulic pumps and a generator ensures the necessary energy supply.
  • An electric flash butt welding unit 9 is arranged in the middle between the two trolleys 3, which is connected to a telescopically extendable and height-adjustable lifting arm 10, which in turn is attached to the machine frame 2 and can be rotated about a vertical axis 11.
  • a rail pulling device 12 is connected to the machine frame 2 by height adjustment drives 13.
  • In the area of one of the two undercarriages 3 there are two lifting rams 14 spaced apart from one another in the cross-machine direction, which are designed to lift the machine frame 2 by resting on the top of the sleeper.
  • the rail pulling device 12 shown enlarged in FIG. 2, for longitudinally displacing the rails 4, consists of two transverse yokes 15 which run transversely to the machine or longitudinal direction of the rail 15 and on each of which a pair of clamping pliers 16 forming clamping pliers 17 are arranged, each around a vertical one or pivot axis 18 extending perpendicular to the track plane are pivotably connected to the transverse yoke 15.
  • the two upper clamps 17 in the drawing are visible in the open position, while the lower clamps 17 are shown in the closed position.
  • Each of the clamping jaws 19, which can be pivoted against the rail web, is connected in an articulated manner to two hydraulic drives 20 in the end region opposite the pivot axis 18.
  • An insulation layer 22 is provided between the piston-side end of the hydraulic drives 2o which run parallel to one another and an articulated part 21 which is connected in an articulated manner to the clamping pliers 17. This reliably prevents a short circuit between the two rail ends 23, 24 to be welded to one another, which is possible in the flash butt welding process.
  • the transverse yokes 15 are each connected to a rail centering device 25 on the side facing each other. This has hydraulic cylinders 27, 28 and 29 arranged symmetrically and parallel or vertically with respect to a rail symmetry plane 26 running in the longitudinal direction of the rail, with pressure stamps 3o provided for abutment against the rail ends 23, 24.
  • All hydraulic cylinders 27 to 29 of the rail centering device 25 are fastened on a support plate 31 connected directly above the clamping jaws 19 to the transverse yoke 15 with stiffening ribs 32, 33 running in the longitudinal direction of the rail.
  • Each transverse yoke 15 is connected in the area opposite the rail centering device 25 to a U-shaped support member 34 which is intended to rest on the rail head.
  • stops 35 are provided to limit the opening movement of the clamping pliers 17.
  • Both transverse yokes 15 are connected to one another in the area of the double hydraulic drives 2o by positioning drives 36 running parallel to these. Like the hydraulic drives 2o, these have an electrical insulation layer 22 at the end on the piston side.
  • the double and Hydraulic drives 2o arranged parallel to one another form, together with the two parallel yokes running parallel to one another, an annular structural unit and are spaced apart from one another in such a way that the flash butt welding unit 9 indicated by dash-dotted lines unhindered on the two rail ends during the use of the rail pulling device 12 or during the rail pulling process 23,24 is deductible for welding.
  • the height adjustment drives 13 shown in FIG. 1 are connected for the height adjustment of the rail pulling device 12 with tabs 37 attached to the transverse yoke 15, but are not shown in FIGS. 2 to 6 for the sake of a better overview.
  • the vertical hydraulic cylinders 27 of the rail centering device 25 are each connected at their free, lower and piston-side ends to a pressure stamp designed as a support roller 39.
  • These support rollers 39 are rotatably mounted on a bracket 4o fastened to the piston about an axis of rotation 41 running transversely to the longitudinal direction of the hydraulic drives 2o or the rail 4.
  • a bracket 4o fastened to the piston about an axis of rotation 41 running transversely to the longitudinal direction of the hydraulic drives 2o or the rail 4.
  • an anti-rotation device for the holder 4o it lies against a vertical and transverse to the longitudinal direction of the rail extending and connected to the underside of the support plate 31 guide rib 42.
  • the rail pulling device 12 which is centered over the rail ends 23, 24 to be welded, is lowered under the action of the drives 13 until the two support members 34 connected to the transverse yokes 15 rest on the rail head. All four clamping pliers 17 are in contact with the stops 35 in the open position (see upper half of the rail pulling device 12 in FIG. 2).
  • the support plates 43 are placed in the area of the support rollers 39 on the sleepers 5 and the two transverse yokes 15 are spaced apart from one another while the two positioning drives 36 are acted on. This longitudinal displacement of the two transverse yokes 15 results in a closing movement of the Clamping pliers 17 until the four clamping jaws 19 rest against the rail web.
  • the two jacks 14 are lowered onto the sleepers 5 in the area of the rail track to be used and thereby slightly lift the adjacent undercarriage 3 from the rails 4.
  • the total of four hydraulic drives 20 are acted on simultaneously, whereby the rail pulling process is initiated to reduce the rail joint gap 44.
  • the rail pulling process is continued until the distance between the two rail ends 23, 24 required for the initiation of the welding process is reached.
  • the rail ends 23, 24 held under tensile stress are subsequently centered on one another by using the two rail centering devices 25.
  • the hydraulic cylinders 27, 28 and 29 are optionally acted on until both rail ends 23, 24 lie in a common alignment line. Bending up of the two rail ends 23, 24 to the desired extent is achieved in that the two support rollers 39 are pressed onto the support plates 43 by acting on the hydraulic cylinders 27. At the same time, an optional lateral alignment of the rail ends can also be achieved by correspondingly loading the left or right hydraulic cylinder 29, which runs perpendicular to the longitudinal direction of the rail. If one end of the rail is too high, a lowering is possible by applying the hydraulic cylinder 28.
  • the flash-butt welding unit 9 is raised with the aid of the lifting arm 1o lowered onto the two rail ends 23, 24 between the hydraulic drives 2o and the two transverse yokes 15 of the rail pulling device 12 (see dash-dotted lines in FIG. 2).
  • the hydraulic drives 2o remain applied to maintain the tension even during the welding process.
  • the upset required for the completion of the welding process, in which the rail ends 23, 24 heated to the melting temperature are pressed against one another with very high force, takes place with the synchronous use of the hydraulic drives 2o and corresponding longitudinal displacement drives integrated in the flash butt welding unit 9.
  • two clamping jaws 46, 47 are arranged on each clamping tongs 45 in such a way that, on the two rail ends 23, 24, either tensile (dash-dotted arrows) or pushing forces (arrows shown with solid lines) ) are transferable.
  • tensile das-dotted arrows
  • pushing forces arrows shown with solid lines
  • To apply the thrust forces only a swiveling of the clamping tongs 45 into the position shown in solid lines is required, so that the clamping jaws 46 opposite the rail centering device 25 are pressed against the rail web.
  • This means that appropriate welding work can also be carried out in summer at elevated temperatures while maintaining the appropriate compressive stresses.
  • the tongs 45 are pivoted by tensile forces into the position indicated by dash-dotted lines.
  • the rail centering device 25 shown in simplified form corresponds to that described in more detail in FIGS.
  • the inner or outer clamping jaws 46, 47 which are not required can also be removed.
