Definitions

  • This invention relates to a novel and innovative method to replace or renew a part or component of a railway track for passenger and/or goods transport.
  • the invention is particularly adapted to replace a ballast formation for a switch and crossing or turnout.
  • the invention is also applicable for replacement of a ballast formation for another part or component of the railway track, e.g. a straight or curved track part.
  • the invention is adapted for ballast comprised from bulk or loose laying material, e.g. pebbles or crushed stone.
  • a turnout is sometimes termed switch; bearers are sometimes termed crossties; adjacent track is sometimes termed neighbour track; digging device is sometimes termed ballast removing means.
  • the object of the invention is to provide a method which requires merely 8 hours out of service time at a stretch for the complete renewal of a turnout of a railway track with overhead power supply. It will be appreciated that the equipment of the overhead power supply (particularly the power supply cables) remains installed during turnout renewal, although the power will be switched off for safety reasons. As such, the overhead power supply provides an interference for the equipment used to carry out the renewal method.
  • the ballast is removed in several layers. These layers can be at the same level, thus adjacent each other. Or the layers can be below each other. If at the same level, the layers are preferably removed simultaneously. If on top of each other, the layers are removed one after the other, starting from the top layer and each time removing a layer at the next lower level.
  • ballast is removed by a single passage of a ballast removing device that preferably advances along/runs over/bears onto the adjacent track.
  • Said device preferably comprises ballast removing means which provide a preferably substantially continuously forward moving ballast removing front. If the ballast is removed in several layers, each layer has its own continuously forward moving ballast removing front.
  • the method is carried out such that one or more of the following applies: successive, forward moving, ballast removing fronts are provided, each at a lower level, as viewed in downstream direction, or adjacent each other; which fronts substantially continuously move forward; which fronts keep a substantially constant mutual spacing in forward direction; which fronts cover substantially the complete width of the ballast bed to be removed, either each one (if at different levels) or together (in case of adjacent fronts, each front preferably covers only part of the complete width of the ballast bed).
  • forward direction is parallel to the lengthwise direction of the track.
  • the ballast removing fronts preferably extend according to a substantially straight line, possibly inclined relative to the forward direction.
  • the old ballast is first moved sideways, as viewed in forward direction, by the ballast removing means, to be collected at e.g. a side of the ballast bed (chain digger).
  • the old ballast is first elevated by the ballast removing means to be collected at e.g. a conveyor system (drum digger).
  • ballast removal is preferably carried out from the co-extensive or neighbour track and the removed ballast is preferably dumped onto a conveyor mechanism at said adjacent track or into a container at said adjacent track.
  • ballast removing means can act simultaneously such that a large removing capacity is provided, while ramping in and ramping out at the longitudinal ends of the track part to be renewed can also be provided in a simple manner by successively switching on and off the more downstream ballast removing means during ramping in respectively ramping out, such that elevating/lifting the ballast removing means can be avoided.
  • ballast removal in layers adjacent each other also allows for simultaneous action of a plurality of ballast removing means such that a large removing capacity is provided.
  • ramping in and ramping out is provided by lowering and lifting, respectively, the ballast removing means or digging device while advancing the ballast removing device.
  • the new ballast bed is installed at the same location. Installing the new ballast bed is preferably carried out during the same passage of the ballast removing device.
  • the ballast removing device and the device to install the new ballast move and/or operate the one after the other and preferably move simultaneously/together, e.g. are integrated in a single installation/vehicle.
  • the turnout is installed on top of the ballast bed. Then the longitudinal ends of the turnout are connected to the track, such that railway traffic can resume.
  • a vehicle is used that is displaceably carried by the co-extensive or adjacent track.
  • the vehicle is provided with wheels adapted to run across rails of the track.
  • This vehicle is preferably equipped with sideways projecting processing equipment to carry out the activities to the ballast bed of concern.
  • Said equipment e.g. comprises one or more substantially horizontally extendable ballast moving means adapted to almost completely cover the ballast bed of the turnout to be renewed.
  • the ballast moving means are adapted to move the ballast.
  • the ballast moving means are adapted to move the ballast across the ballast bed, towards a ballast elevating means located at one side of the ballast bed of the turnout to be renewed, preferably the side closest to the vehicle.
  • the ballast moving means are adapted to take up the ballast to slightly elevate it and transfer it to a conveyor that moves the ballast towards a ballast elevating means located at the side of the ballast bed of the turnout to be renewed, preferably the side closest to the vehicle.
  • This ballast elevating means brings the ballast from substantially the level of the ballast bed to a higher level from where the ballast can be further processed, e.g. be brought to a container, possibly being part of the same vehicle.
  • the ballast elevating means transfers the ballast to a conveyor at higher level, the output of which ends e.g. above the container.
  • the design is such that the inlet of the ballast elevating means covers or crosses or overlaps the outlet of a and preferably each ballast moving means, such that a ballast moving means transports ballast directly towards the ballast elevating means that takes up said ballast.
  • a ballast moving means preferably comprises one or more movable members engaging the ballast.
  • the movement of said movable members causes the ballast to move in a predetermined direction while tumbling across ballast or the substrate underneath.
  • the ballast moving means it is not required for the ballast moving means to take up ballast.
  • the ballast moving means it is simply required for the ballast moving means to push or draw or otherwise propel the ballast while supported by the underneath ballast or substrate, possibly after loosening said ballast.
  • such movable members move according to an endless loop.
  • such movable members move in succession, preferably keeping a mutual spacing.
  • the movable members move/circulate/orbit in a substantially horizontal (chain digger) or vertical plane (drum digger) or around an upward, preferably substantially vertical axis (chain digger) or around a substantially horizontal axis (drum digger).
  • the moving means comprises one or more drums carrying the movable members at the circumferential surface.
  • Said movable members engage the ballast and immediately lift it or take it up to dump it onto a conveyor that moves the removed ballast towards the side of the ballast bed.
  • Said drum preferably rotates around a substantially horizontal axis.
  • ballast moving means are preferably adapted to move the ballast selectively in any of two opposite directions and/or are preferably adapted to move up and down, e.g. to adapt the level at which the ballast is engaged.
  • ballast moving means are preferably designed to adapt its attitude horizontally and/or vertically, e.g. by adapting the angle of their extension.
  • ballast moving means are preferably designed to adapt their magnitude of coverage of the ballast bed, e.g. by being movable or extendable or adapting their angle of extension.
