Definitions

  • the invention relates to a method for operating a track maintenance machine on a track section with an overhead line network, wherein a power supply to the track maintenance machine is optionally interrupted by means of a pantograph from an overhead line when crossing a section separation of the overhead line network.
  • the invention relates to a track construction machine for carrying out the method.
  • AT 517771 A1 discloses a method for operating a track construction machine, which is supplied by means of a pantograph from an overhead line network.
  • the overhead line network is divided into several sectors (feeding areas), which are separated from each other by transfer points.
  • a so-called section separation causes an electrical separation of the contact wires of the adjoining sectors while maintaining the mechanical contact wire pretension.
  • the invention is based on the object of specifying a method of the type mentioned in which, compared to the prior art, the safety when driving over road separations is increased. Another object of the invention is to specify a corresponding track-laying machine.
  • Determining the position of the contact point is also advantageous when there is only one contact wire. This makes it possible to check whether the overhead line is still within a standard range (e.g. TR940 for the route network in Austria) and whether the desired lateral displacement of the overhead line is being observed. In this way, the measuring arrangement also functions as a control device for the overhead line.
  • a standard range e.g. TR940 for the route network in Austria
  • a driving speed of the track construction machine is continuously recorded, with the pantograph being automatically lowered if the speed is below a minimum speed and more than one contact point on a contact strip of the pantograph is detected.
  • equalizing currents between two supply areas can cause a contact wire to heat up very quickly.
  • softening occurs at temperatures above 100°C, causing the contact wire to lose its pretension or to tear.
  • the pantograph is automatically lowered immediately. This is particularly relevant for track construction machines, because these usually have a very low working speed ( ⁇ 2 km/h).
  • a temperature of a contact strip of the pantograph is additionally measured by means of the measuring arrangement. This ensures that the pantograph is lowered when the temperature exceeds a predetermined threshold. Too high a resistance between the contact strip and the contact wire can also lead to impermissible heating within a feed area.
  • the possible uses are increased if the track-laying machine is supplied with power from an energy source arranged in the track-laying machine when the pantograph is lowered. With this improvement, it is not just the existing kinetic energy of the track construction machine in motion that is decisive for crossing the section separation. As soon as the pantograph is lowered, the energy is supplied, for example, from an electrical energy store, a motor-generator unit or a fuel cell.
  • the contact points are advantageously detected by means of pressure sensors arranged on the current collector.
  • the direct attachment of pressure sensors to the pantograph ensures error-free detection of the contact points.
  • Optical or other non-contact measuring arrangements sometimes lead to incorrect results.
  • a detection of pressure and shock loads carried out by means of the pressure sensors also enables faults to be found in the overhead line. Unevenness in the overhead line is a major hazard, especially at high speeds. With the extended measurement arrangement, these danger spots can be identified.
  • pressure changes are detected by means of an optical waveguide arranged under a contact strip, by using a detector unit connected to the optical waveguide to transmit light waves into the optical waveguide and to evaluate reflected light waves.
  • the optical fiber is used as the sensor element of a so-called Fiber Bragg Grating Sensor (FBG sensor).
  • FBG sensor Fiber Bragg Grating Sensor
  • the fiber optic cable is not live (the electrical resistance is typically 10 16 W-cm according to DIN 53482) and can therefore be mounted on the underside of the contact strip without any problems.
  • Temperatures and strains can be measured using the FBG sensor. Due to the targeted arrangement of the optical waveguide, there are on the one hand contact forces measurable at the contact points and the positions of the contact points, resulting in the number of contact points. On the other hand, temperatures of the contact strip can also be measured. This means that another measured variable is available to define a criterion for lowering the pantograph. For example, a temperature threshold is specified, when it is reached the pantograph is automatically lowered.
  • a speedometer is arranged to continuously record the travel speed of the track construction machine, the speedometer and the measuring arrangement being coupled to an evaluation device and the evaluation device being connected to a control device for controlling a lifting drive of the pantograph.
  • the pantograph is automatically lowered as soon as a slow speed causes the vehicle to remain at the transfer point for too long.
  • pressure sensors for detecting pressure forces between a contact strip and the overhead line are arranged on the pantograph.
  • the compressive forces enable the contact points to be detected immediately, which means that the number of these contact points can be determined clearly and reliably.
  • an optical waveguide is arranged under the sliding strip, the optical waveguide being connected to a detector unit for transmitting light waves and evaluating reflected light waves.
  • the physical properties of the fiber optic cable enable precise detection of the contact points and provide the necessary electrical insulation between the pantograph and the detector unit.
  • a current collector with several contact strips is used, with an optical fiber being arranged under each contact strip. Due to the redundancy that is thus available, particularly reliable measurement results can be achieved. In particular, with this arrangement, conclusions can be drawn in a simple manner about the type of section separation. For example, section insulators with several curved guide elements can be identified.

So that the current collector 5 can be lowered in good time, according to the current state of the art, a great deal of planning is required and a great deal of attention and very good knowledge of the route on the part of an operator of the track construction machine 1 .
