Definitions

  • the invention relates to a ballast clearing device for a track construction machine for collecting ballast, with an endless clearing chain that is guided along a transverse guide, an ascending longitudinal guide and a descending longitudinal guide, with a discharge point being arranged between the ascending longitudinal guide and the descending longitudinal guide.
  • the invention also relates to a track construction machine with a corresponding ballast clearing device and a method for operating the track construction machine.
  • a generic ballast clearing device is used, for example, in a EP 0 621 371 A2 known track construction machine is used to renew or lay a railway track.
  • the old rails are first lifted off the sleepers and moved outwards to the side.
  • the old sleepers are then picked up using a sleeper pick-up device and transported away on conveyor belts.
  • excess ballast is picked up using the ballast clearing device and thrown to the side of the ballast bed.
  • the ballast bed surface is smoothed using a smoothing device before new sleepers are laid using a sleeper depositing device. Finally, the rails in front are positioned on the new sleepers.
  • the same track construction machine can be used to lay a new track. To do this, the working direction is reversed. The sleeper pick-up device and the ballast clearing device are not in operation in this working mode. New sleepers are laid on an already smoothed ballast bed using the sleeper deposit device. The The positioning of the rails on the new sleepers is carried out using guide devices arranged on the track construction machine. A separate machine is required to smooth the ballast bed.
  • a rotating ballast clearing device is available from the EP 1 162 311 A2 This makes it possible to use a track construction machine to renew a track in both directions.
  • the sleeper pick-up device and the sleeper deposit device are converted accordingly so that, depending on the direction of work, the old sleepers are first picked up and the new sleepers are deposited after the ballast bed has been smoothed.
  • Coupling devices are provided to simplify this conversion process.
  • the invention is based on the object of improving a ballast clearing device of the type mentioned at the beginning in such a way that the possible uses are expanded with little conversion effort. It is also an object of the invention to provide a track construction machine which makes use of the expanded possible uses. In addition, an advantageous method for operating such a track construction machine is to be provided.
  • a clearing blade is arranged on the ballast clearing device almost parallel to the transverse guide, with a lower edge of the clearing blade extending at least partially below a clearing level of the clearing chain in a working position.
  • the ballast clearing device can be used in the opposite direction to a normal working direction without the entire ballast clearing device having to be rotated.
  • the discharge point is in front of the transverse guide of the clearing chain.
  • the clearing blade in the working position causes ballast to collect between the clearing blade and the clearing chain and to be transported to the discharge point by means of the clearing chain along the ascending longitudinal guide.
  • the position and shape The lower edge of the dozer blade determines the level and contour of the resulting bedding surface. The resulting smooth profile of the bedding surface allows new sleepers to be laid down immediately.
  • the lower edge of the dozer blade advantageously has a contour with several sections, with a middle section and side sections being lower in the working position than sections between the middle section and the side sections.
  • the resulting surface profile of the ballast bed forms a particularly stable support for sleepers. Specifically, there are raised sections of the ballast bed under the rails mounted on the sleepers. In the middle section and in the side sections, the ballast bed surface is lower.
  • the raised sections of the ballast bed profile serve as supports for the sleepers in the area of the rails, so that vehicle forces acting on the rails cannot cause the sleepers to tip over.
  • At least one cross conveyor belt is arranged below the discharge point. Using this cross conveyor belt, the collected ballast is transported away to the side and discharged next to the track. In another embodiment, it can be useful to transport the collected ballast further within a track construction machine. For example, the material is cleaned, possibly with storage in a material wagon coupled to the track construction machine.
  • two cross conveyor belts are arranged parallel to each other, with the cross conveyor belts being driven in opposite conveying directions. With such an arrangement, the collected ballast is thrown onto both sides of the track and is available there for subsequent ballasting of new sleepers that have been laid.
  • a preferred blade is characterized by its lower section being bent or kinked in the direction of the clearing chain. This allows an upward movement of the material The gravel is then drawn off in the direction of the clearing chain. This results in an optimized flow of gravel all the way to the discharge point.
  • the clearing chain is guided in an ascending transport channel and a descending empty channel, with the clearing blade being attached to the channels with supports. This creates an inherently stable arrangement. During operation, the ballast forces acting on the clearing blade are absorbed by the load-bearing elements of the transport channel and the empty channel.
  • the clearing blade is connected to a pneumatic, hydraulic or electric actuator.
  • a clearing blade can be brought into the working position without assembly operations, whereby a remote-controlled actuation of the actuator is provided in particular. In this way, no operating personnel are required in the work area where safety is at risk in order to carry out manipulations on the ballast clearing device or the clearing blade.
  • stiffening ribs are advantageously extended over the edge of the clearing blade and also serve as supports for attaching the clearing blade to load-bearing elements of the ballast clearing device.
  • a track construction machine comprises a machine frame which can be moved along a track on undercarriages, wherein a first sleeper device for receiving sleepers and a second sleeper device for depositing sleepers are arranged on the machine frame, wherein a ballast clearing device as described above is arranged between the first and the second sleeper device and wherein the first sleeper device is optionally set up for receiving and depositing sleepers.
  • a track construction machine can be operated in two working directions, i.e. in both directions of travel of a track. In one working direction for renewing a track, old sleepers are picked up and new sleepers are deposited, wherein in between with the ballast clearing device excess ballast is removed. The clearing blade remains out of operation in this working mode.
  • the track construction machine works in a mode for laying a new track.
  • a previously filled ballast bed is profiled using the ballast clearing device using the clearing blade in order to ensure an optimal support for the placement of the new sleepers using the first sleeper device.
  • the second sleeper device remains out of operation in this mode.
  • an actuator for the clearing blade and a height actuator for adjusting the height of the ballast clearing device relative to the machine frame are coupled to a common control device. This allows a coordinated height adjustment of the clearing blade relative to the track on which the track construction machine travels.
  • the track construction machine described has a first working direction for renewing an existing track.
  • the track construction machine is moved forward in a second working direction opposite to the first working direction, with the ballast clearing device being operated to profile a ballast bed with the clearing blade in the working position.
  • Two different working modes are therefore available for the same track construction machine, with only a change in working direction and minor adaptations of the ballast clearing device and the sleeper devices taking place. In particular, there is no need to replace or laboriously rotate the ballast clearing device around a vertical axis.
  • the clearing blade is moved from an inoperative position to the working position in one set-up process. This is done in particular by a swivel movement that is carried out by means of an actuator.
  • an actuator of the clearing blade and a height actuator for adjusting the height of the ballast clearing device relative to the machine frame are controlled by a common control device in order to achieve a surface level of the ballast bed. In this way, optimal profiling of the ballast bed can be achieved, taking into account the position of the machine frame.
  • This variant is improved by detecting the surface level of the ballast bed using a sensor system, whereby a sensor signal is fed to the control device and the ballast bed is profiled to a target level using a control system.
  • a sensor signal is fed to the control device and the ballast bed is profiled to a target level using a control system.
  • the exemplary track construction machine 1 shown can be used in a first working direction 2 to renew an existing track 3 and in a second working direction 4 to lay a new track 3.
  • the machine 1 works in what is known as an assembly line process with a continuous forward movement.
  • a machine frame 5 is supported on several chassis 6, 7, with at least one crawler chassis 6 being provided for driving on a ballast bed 8.
  • Rail chassis 7 are used for driving on rails 9 to be dismantled or rails 9 that have already been laid.
  • the height-adjustable crawler chassis 6 is used to raise the machine frame 5 with the associated rail chassis 7 during a rail change or during rail laying.
  • the machine frame 5 is additionally supported with a height-adjustable support 10 on a rail-guided carriage 11. In this way, a gap is created in which rails 9 can be moved by means of height- and side-adjustable rail guides 12.
  • a ballast clearing device 13 for collecting ballast 14 is arranged in front of the crawler track 6, and in front of it a first sleeper device 15 for selectively collecting and depositing sleepers 16.
  • this second sleeper device 17 is out of operation ( Fig.2 ).
  • the respective sleeper device 15, 17 is coupled to conveyor means 18 for transporting sleepers 16 within the track construction machine 1.
  • the first sleeper device 15 permanently comprises all components for lifting sleepers 16 from the ballast bed 8 or depositing them on the ballast bed 8.
  • the work processes are reversed.
  • the first sleeper device 15 comprises a coupling device to which components for sleeper reception or sleeper storage are optionally attached, as shown in the EP 1 162 311 A2 described.
  • FIGS. 3 to 6 show the ballast clearing device 13 in different variants.
  • An endless clearing chain 19 consists of chain links 20 that can move relative to one another and are equipped with scraper blades.
  • the clearing chain 19 picks up ballast 14 between the scraper blades and transports it in the running direction 21 of the chain 19.
  • the clearing chain 19 is guided along a transverse guide 23, an ascending longitudinal guide 24 and a descending longitudinal guide 25.
  • the transverse guide 23 runs along a crossbar 26 that serves to pick up the ballast 14.
  • the ascending longitudinal guide 24 runs along a transport channel 27. In this transport channel 27, the picked up ballast 14 is transported upwards to a discharge point 28.
  • a chain drive 30 is arranged at the deflection point between the transport channel 27 and the empty channel 29.
  • a sprocket drive is preferably used, which is coupled in particular to a chain tensioning device. This type of drive is robust and durable and ensures that the clearing chain 19 rotates evenly.
  • the position of the crossbeam 26 relative to the ballast bed 8 determines the amount of ballast taken up.
  • the height of the crossbeam 26 is adjusted by changing the position of a unit formed by the crossbeam 26, transport channel 27, empty channel 29 and chain drive 30 relative to the machine frame 5. For this purpose, this unit is connected in an articulated manner to the machine frame 5 via at least one height actuator 31.
  • the height actuator 31 is controlled by means of a control device 32.
  • At least one cross conveyor belt 33 is arranged below the discharge point 28 in order to transport the collected ballast 14 laterally and to dump it at the edge of the ballast bed 8.
  • Two cross conveyor belts 33 are provided for dumping the ballast 14 onto both sides of the ballast bed 8, with parallel alignment and opposite conveying directions.
  • the ballast clearing device 13 works in a known mode.
  • the scraper blades clear ballast 14 from the ballast bed 8 and convey it in the direction of the transport channel 27.
  • a lower edge of the crossbeam 26 or a lower envelope surface of the clearing chain 19 guided along the cross guide 23 determines a clearing level 34, above which the ballast bed 8 is removed.
  • a new operating mode is used in the opposite working direction 4.
  • a clearing blade 35 is arranged parallel or approximately parallel to the crossbeam 26.
  • a lower edge 36 of the clearing blade 35 projects at least partially below the clearing level 34 of the crossbeam 25 or the clearing chain 19.
  • the crossbeam 26 is positioned such that the clearing level 34 of the clearing chain 19 is above an existing surface level 37 of the ballast bed 8 and the lower edge 36 of the clearing blade 35 is below this existing surface level 37.
  • ballast clearing device 13 with the clearing blade 35 also picks up ballast 14 from the ballast bed 8 in the second working direction 4, with the lower edge 36 determining a surface level 38 of a resulting surface contour of the ballast bed 8. Specifically, so much ballast 14 accumulates in front of the clearing blade 35 that it is captured by the clearing chain 19 and transported in the direction of the transport channel 27.
  • the clearing blade 35 is attached to the ballast clearing device 13 during a set-up process.
  • the clearing blade 35 is adjustably arranged on the ballast clearing device 13.
  • it is attached to the side channels 27, 29 by means of hinged supports 39, as in Fig.6 Alternatively, fastening to the cross beam is possible. 26 ( Fig.5 ).

  • At least one pneumatic, hydraulic or electric actuator 41 is arranged to change the position of the clearing blade 35 between an inoperative position and the working position.
  • the actuator 41 is controlled by the control device 32 and is also used for fine adjustment of the clearing blade 35 relative to the ballast bed 8.
  • the clearing blade 35 is pivoted about a joint 42.
  • a joint control of this actuator 41 and the height actuator 31 enables a controlled tracking of the resulting surface level 38 of the surface contour.
  • the resulting surface level 38 is continuously recorded by means of a suitable sensor system 43.
  • a contactless sensor is advantageously used.
  • a corresponding sensor signal is fed to the control device 32.
  • a lower section 44 of the blade 35 is either straight ( Fig.3 ) or bent in the direction of the crossbeam 26 ( Fig.4 ). In a variant not shown, the lower section 44 is bent in the direction of the crossbeam 26. In the curved or bent variant, the ballast 14 is specifically conveyed upwards to the crossbeam 26, whereby a particularly efficient ballast pickup of the ballast clearing device 13 is achieved.
  • FIG. 7-9 show cross-sections of the ballast bed 8 in successive stages of the processing process according to Fig.2 .
  • Fig.7 the ballast bed 8 driven over by the crawler track 6 is shown.
  • the ballast 14 picked up by the ballast clearing device 13 is thrown off to the side by means of the cross conveyor belts 33 ( Fig.8 ).
  • Fig.9 shows the clearing blade 35 with an advantageous contour of the lower edge 36.
  • a middle section 45 and side sections 46 are lower than the two intermediate sections 47 arranged between them.
  • these intermediate sections 47 form raised Ballast supports 48 for the sleepers 16.
  • the contour of the lower edge 36 is adapted to the gauge of the track 3 and the sleepers 16 used in such a way that the ballast supports 48 are positioned below the rails 9 that are later attached to the sleepers 16. This ensures stable support of the sleepers 16 in the ballast bed 8.
