Definitions

  • the invention relates to a tamping unit for tamping a track bed of a track body, the tamping unit having a longitudinal direction running essentially in the direction of a longitudinal extension of the track body, the tamping unit having at least one displacement device on which at least one support box is arranged, with several on the support box in the direction their longitudinal axes adjustable and longitudinally pivotable tamping tines are arranged, wherein the tamping tines are arranged in at least two spaced apart and transversely to the longitudinal direction rows, wherein at least one tamping tine of one row and at least one tamping tine of the adjacent row are essentially aligned in the longitudinal direction, and wherein at least one of the essentially aligned tamping ax can be pivoted in the longitudinal direction independently of the other essentially aligned tamping ax.
  • the invention also relates to a tamping machine for tamping a track bed of a track body.
  • Track bodies usually consist of a track arranged on a track bed, consisting of two rails running parallel to one another and in the longitudinal extension of the track body, which are arranged on sleepers that are spaced apart from one another and run transversely to the longitudinal extension.
  • the track bed arranged under the track can consist of gravel.
  • tamping units which are equipped with tamping tines
  • these are arranged on support boxes which are lowered and raised during tamping.
  • all tamping axles of a support box are lowered at the same time or all tamping axles dip into the track bed at the same time.
  • the tamping tines usually in pairs, can be swiveled to the side with the help of a mechanical adjusting mechanism on the support box. As a result, some of the tamping tines of the carrying case do not dip into the track bed.
  • the tamping ax of known tamping units can be adjusted in pairs with the help of a mechanical exciter (e.g. an eccentric shaft or a hydraulic cylinder) that is connected to the adjusting mechanism - usually with a frequency of 25 to 50 Hz and a deflection from 2 to 8 mm - can be made to vibrate.
  • a mechanical exciter e.g. an eccentric shaft or a hydraulic cylinder
  • tamping takes place cyclically or almost continuously.
  • the tamping machine is braked for each individual tamping process, whereas with continuous tamping only the part of the tamping machine on which the tamping unit and the operating area of the tamping unit are arranged needs to be braked.
  • the tamping machine can be a vehicle traveling on the rails or a vehicle traveling alongside the rails.
  • a lifting and straightening unit that is independent of the tamping unit also acts on the rails of the track during tamping and adapts the position of the track to a specified target track position based on an ACTUAL track position measured with a measuring device.
  • Tamping units with tamping tines are, for example, off U.S. 3,430,579 A and AT 227 750 B known.
  • Other tamping units with tamping tines are, for example, off AT 385 298 B , U.S. 4,369,712 A , WO 2016/054667 A1 and GB 1,358,762 A known.
  • the tamping tines can only be immersed or pivoted together into the track bed, which means that targeted tamping that is adapted to the particular nature of the track bed is not possible.
  • the tamping unit, the lifting and straightening device and the measuring device are three working units that are independent of one another.
  • the measuring device for detecting the actual track position is arranged outside the tamping unit, which makes it difficult to correct the track position.
  • the invention is based on the object of an improved tamping unit, an improved tamping machine and a to provide an improved method for tamping a track bed.
  • At least one of the essentially aligned tamping ax can be pivoted in the longitudinal direction independently of the other essentially aligned tamping ax.
  • the ballast can be pushed under the sleeper to different degrees on both sides of the sleepers of the track, so that the tamping process can be individually adapted to the conditions of the track bed in the area of each sleeper.
  • tamping tines are essentially aligned in the longitudinal direction means, within the scope of the invention, that they are arranged essentially in a straight line as seen in the longitudinal direction. Within the scope of the invention, however, tamping tines that are arranged slightly offset from one another as seen in the longitudinal direction are also regarded as being essentially in alignment.
  • both tamping tines can be pivoted in the longitudinal direction independently of the other tamping tick, and can be pivoted towards or away from the other tamping tick as required. This allows the track bed to be compacted even more specifically and effectively.
  • a tamping unit since in a tamping unit according to the invention at least one of the tamping tines can be adjusted in the direction of its longitudinal axis independently of other tamping tines, individual areas on the track body can be left out when tamping. Furthermore, on Tamping unit weight can be saved, since the need to pivot the tamping tine to the side is eliminated. In addition, the entire mass of the support box does not have to be lowered and raised when tamping.
  • all tamping tines of the tamping unit can be adjusted independently of one another in the direction of their longitudinal axis, so that any number of tamping tines adapted to the given circumstances can dip into the track bed during tamping.
  • tamping can be particularly effective in all areas of the track system, including switches, for example.
  • tamping tines in a row are arranged essentially aligned in the longitudinal direction, and if at least one of the essentially aligned tamping tines is independent of the other essentially aligned tamping tine is pivotable in the longitudinal direction.

  • a tamping unit designed in this way can thus compact the track bed in a more targeted and effective manner over the entire length of the rows.

  • the track bed can be particularly strongly compacted in that area or areas on which the highest pressure is exerted by passing rail vehicles.
  • each of these carriers can be arranged on the support box via an adjusting device, for example in a preferred embodiment with carriers.
  • the carriers can also be pivoted transversely to the longitudinal direction and thus altogether obliquely to the longitudinal direction on the support box.
