Definitions

  • the invention relates to an alignment device for aligning at least one rail in the track construction of solid carriageways, comprising a support block, with an inner track section, an outer track section and a rail mount, a first lifting unit which has a first central axis and for lifting the support block in the direction of the first central axis is formed, a second lifting unit which has a second central axis and is designed to lift the support block in the direction of the second central axis, wherein the support block has a transverse axis that is substantially perpendicular to the first central axis, and wherein the rail receptacle is a support surface for a rail foot has, which includes a fixed, preset angle of attack with the transverse axis.
  • the tracks are then aligned and fixed in the track trough before it is then poured with suitable materials such as concrete or asphalt.
  • suitable materials such as concrete or asphalt.
  • the rails or their support structures are firmly enclosed by the potting material.
  • the potting material then hardens, creating a firm, form-fitting and / or material-locking bond. After the grouting material has hardened, the tracks are fixed.
  • alignment devices which allow the position of the rails to be precisely aligned. Furthermore, the aligned position is ensured by the alignment device until the construction work is completed. Due to the harsh construction site environment, there are special stability requirements for the alignment devices. Construction site transports are already being carried out over the not yet grouted tracks. The potting is often carried out by a potting trolley traveling on the aligned tracks. Especially when building track systems for high-speed lines, there are high accuracy requirements for the alignment of the rails. It is necessary to align the rails in terms of height, relative lateral position to the track trough, cant, rail inclination and track width.
  • the rails are usually inclined around their longitudinal axis at a defined angle to the center of the track.
  • the outside rail of the track is elevated relative to the inside rail. Even in the case of such a cant, the rail inclination to the center of the track must be ensured.
  • a lifting system for a track to be laid in a slab track for rail vehicles which has two height-adjustable lifting devices which are arranged under the first and second rails of the track.
  • the height is adjusted using two lifting spindles which are attached to the lifting devices on the inside and outside of the track.
  • the lifting spindles are arranged offset relative to a longitudinal axis of the rail to be aligned.
  • the rail is mounted on a pivot bearing device of the lifting device and is pivotable about its longitudinal axis.
  • the setting of the track width i.e. the relative distance between the rails of a track, is carried out using a lane-keeping element.
  • the lane-keeping element is hooked into the holding brackets of the lifting devices, which fix the rail inclination.
  • the retaining clips are sensitive to damage, which can impair reusability and accuracy of alignment.
  • the receiving surfaces of the retaining clips to which the lane-keeping element is placed can be damaged in the event of repeated or improper handling, so that the setting of the angle of attack is no longer possible with sufficient accuracy.
  • the setting angle is adjusted in combination with the connecting element. It is not possible to set the angle of incidence of just one rail individually.
  • the structure with the pivot bearing device is complex and prone to errors. Due to the arrangement of the lifting spindles, the adjustment of a spindle inevitably results in a change in position of the rail along or around several spatial axes, which makes alignment more difficult.
  • a device for lifting and straightening tracks of the slab track which has an integrally formed cross member.
  • the traverse is designed in such a way that it engages under both rails of the track at the same time and fixes them to one another.
  • the device is lifted by means of lifting spindles arranged inside the track.
  • the high weight and the great length of the device make it difficult to use on construction sites.
  • it is difficult to individually align a single rail.
