Machine and method for profiling and distributing gravel of a track field of technology

[01] The invention relates to a machine for profiling and distributing

Gravel of a track, with a frame supported on rail bogies and with lateral ballast receivers which are adjustably mounted on the frame, each ballast receiving means being provided with a conveyor drive. In addition, the invention relates to a

corresponding procedure.

State of the art

[02] Such machines are usually used after

Tamping work to distribute the ballast ballast and profiling. Above all, the depressions on both sides of the rails created during the clogging of the sleepers are to be filled up with ballast. Specifically, the ballast by the ballast receiving facilities of the

Bettungsflanken moved up to the rails.

[03] If the machine is used behind a tamping machine, the working speed must be equal to the slow feed of the

Track tamping machine adapted. Then the speed of a rigid plow shield is not enough to turn the ballast into a dynamic one

Move upwards. Therefore, in the prior art ballast pick-up devices are equipped for slow working trips with a conveyor drive. According to EP 0 092 886 A1, plow plates, for example, are set in an oscillating motion in order to convey the ballast upwards.

[04] The CH 550 282 A is a ballast pick-up with a

circulating conveyor chain or equipped with conveyor belts to convey ballast upwards on a bedding flank. The US 4,707,935 A discloses a ballast plow with laterally arranged drums, which are set for ballast conveyance by means of a drive in rotation. Summary of the invention

[05] The invention is based on the object of specifying an improvement over the prior art for a machine of the type mentioned at the beginning and a corresponding method. In particular, a more flexible applicability of the machine should be achieved.

[06] According to the invention, these objects are achieved by a machine

according to claim 1 and a method according to claim 13. Dependent claims indicate advantageous embodiments of the invention.

[07] The machine is designed such that the upper contour lines of the machine at least in a non-working position below a

Limiting plane are arranged, which is sloping in the direction of work and passes through a viewing area of a cab of an engageable with the machine at the rear end rail vehicle. Thus, the machine can be used as a feed carriage of the rail vehicle, with a sufficient view from the cab is ensured on the track.

In any case, the machine is as Vorlaufwagen in non-working position

Railways in regular operation (for example, transfer trips) movable. In this case, for example, the ballast conveyors are locked in a position which lies within a predetermined light profile. Even in a working position, possibly only individual components protrude over the

Limiting level, so that even in the working mode, which is characterized by a low speed, is given from the cab enough visibility to the front.

[09] Gravel profiling and gravel distribution can then be carried out flexibly independently of the sequence within a rail vehicle network. This provides in particular the possibility to couple the machine in front of a track tamping machine and to use excess ballast from the ballast edges for lifting and submerging the track. In this way, a separate ballast supply can be omitted in many cases and thus be saved in a track processing gravel. Even previously dropped at the ballast edges gravel is displaced by means of the machine according to the invention on the track. A use of a tracked machine operated separately from the track tamping machine for Ballast Distribution System is no longer necessary.

It is favorable if the boundary plane and a through

Radaufstandspunkte the rail bogies formed reference plane an angle between 3 ° and 10 °, in particular between 5 ° and 8 °, include. The free view of the track is then sufficient for all applications, so that the machine can be used anywhere.

[1 1] A further development of the machine envisages that the machine comprises, above each rail of the track, a ballast distribution device for distributing the ballast on both sides of each rail. This is done in an advantageous manner targeted ballasting of the track at the points of a

subsequent submission.

It is also useful a cross conveyor for lateral ejection of the

Ballast. This is used, for example, when of the

Bettungsflanken too much gravel is added and a storage of the excess gravel next to the track is desired.

In a further improvement of the machine this includes a center

arranged longitudinal conveyor belt to gravel of the

To transport ballast pick-up devices to a catchment funnel. This additional ballast conveyor increases the adjustability of the ballast pick-up devices and simplifies the arrangement of the individual machine components below the boundary plane.

[14] Conveniently, there is a ballast silo at the collecting funnel

shot to temporarily store gravel when needed. A

irregular gravel distribution on a track to be processed can be easily compensated in this way over a longer distance.

Another simplification of the machine structure provides that the

Longitudinal conveyor belt is pivotable by means of a Versteilantriebs from a working position to a non-working position. With this measure, in particular a larger collecting funnel or ballast silo can be used. The longitudinal conveyor belt conveys only in working position the ballast in the catching funnel and is for the non-employment under the

Lowered boundary level.

[16] For a simple machine control, it is advantageous if the respective ballast receiving device is adjustable by means of a pivot drive about a pivot axis extending orthogonal to an associated ballast edge. To avoid lateral obstacles, the ballast pick-up device is pivoted upward only about this pivot axis, without predetermining the profiling

Bedding flank angle to change.

An advantageous expression of the machine provides that the respective

Ballast receiving device comprises a screw conveyor. This ensures effective support of the ballast, regardless of

Grain sizes and the degree of contamination of the track bed. With the

Conveyor screw is introduced on the one hand in the ballast kinetic energy to loosen this. On the other hand, the auger and an attached plow shield serve as a conveyor of the ballast.

In a simple design is also provided that the machine is designed without its own drive. This allows a particularly compact design, without restricting the benefits. Of the end-dockable rail vehicle is only a thrust to

Overcoming the driving resistance of the machine apply. in the

Contrary to common gravel plows need the

Ballast receiving devices of the present machine due to the existing conveyor drives no feed force.

For better usability of the machine, it makes sense, if on

front end of the machine is arranged a working direction camera. Then by means of the transferred into the cab

In any case, camera images also ensure an unrestricted view of the track during operation.

[20] In addition, it is advantageous if the machine comprises a machine control, which is set up for data exchange with a controller of the engageable rail vehicle. This facilitates the arrangement of the machine within a rail vehicle network. [21] The inventive method provides that the machine as

Vorlauffahrzeug designed as a track construction machine

Rail vehicle receives by means of ballast receiving devices located laterally of the track ballast and deposited in a central region of the track. This creates an effective method for gravel profiling and ballast distribution in the context of a track rehabilitation.

An advantageous development is given when the position of the respective ballast receiving device is changed by means of a control of the track-laying machine to obstacles located laterally of the track

dodge. In this case, position data stored in the track-laying machine or detected by means of detection devices can also be used by obstacles.

For a simple use of the machine, it makes sense if the

Ballast receiving devices and optionally a conveyor belt and a ballast distribution device by means of associated drives for a

Transfer trip to be brought into a non-working position. in the

Worker use these components in an adjustable

Working position, whereby the use of the machine is optimized.

Ballast distribution equipment and cross conveyor belt Description of the embodiments

[25] The machine 1 shown in FIG. 1 for profiling and distributing

Gravel 2 is movable by rail trolleys 3 on a track 4. By way of example, the machine 1 as a launch vehicle to a than

Track tamping machine (line tamping machine or universal tamping machine) trained rail vehicle 5 coupled. The tamping machine comprises a lifting / straightening unit 6 for lifting and straightening the track 4, whereby a predetermined track position is produced. To fix this track position, the track 4 is supported with a Stopfaggregat 7.

[26] Also the coupling in front of other track-laying machines (for example Dynamic

Track stabilizer) or ordinary traction vehicles (for transfer trips) may be useful.

Often at ballast edges 8 excess gravel 2 is present or there additional gravel 2 is deposited. With the present machine 1, this ballast 2 is picked up and placed in the track 4 at the points to be stuffed. For this purpose, the machine 1 comprises a gravel receiving device 9 on both sides.

[28] The structure of the machine 1 is designed so that the upper

Outlines 10 are arranged at least in a non-working position of the machine 1 below a boundary plane 1 1. At the

Embodiment of FIG. 1 is also during a

Working operation of the case when the ballast receiving devices 9 are swung laterally into a working position. In non-working position, the machine 1 is movable without restrictions on railway lines in regular operation, being coupled as a forward vehicle to a rail vehicle 5 arranged behind it.

[29] The boundary plane 1 1 is formed in a working direction 12 with respect to a by Radaufstandspunkte 13 of the rail bogies 3

Reference plane 14 sloping at an angle of about 5 ° to 8 °, wherein the boundary plane 1 1 extends through a viewing area 15 of a cab 16 of the coupled rail vehicle 5. This means that the boundary plane 1 1 above the rear end 17 of the machine. 1

opposite to the wheel support points 13 of the rail bogies 3 formed reference plane 14 usually at a height of about 2.5m to 3.0m runs.

[30] The supporting component of the machine 1 is a frame 18 which

is formed, for example, welded together steel tubes and is supported on the rail chassis 3. On this frame 18 are on each side of suspension devices 19 and actuators 20 the

Ballast receiving devices 9 adjustable attached. in the

Embodiment promote the ballast pickup devices 9 the ballast 2 on a centrally arranged longitudinal conveyor 21. In a simpler form, the ballast pickups 9 throw the ballast 2 in the rail 22 directly on the track 4 or the respective ballast pickup 9 promotes the ballast 2 via its own lateral Longitudinal conveyor belt upwards.

[31] The respective illustrated ballast pick-up device 9 comprises a

Conveying screw 23, which is set by means of the conveyor drive 24 in rotation and the ballast 2 along a channel-shaped plow blade 25 transported upwards. Alternatively, other ballast receivers 9 with conveyor drive 24 may be used, e.g. Conveyor chains,

Vibration drives etc.

[32] In the embodiment, each rail 22 is its own

Assigned ballast distribution device 26, wherein the ballast means

Longitudinal conveyor belt 21 or in a simplified variant directly by means of the ballast receiving means 9 is supplied. The respective

Ballast distribution device 26 has adjustable drives

Outlets on, with each set opening width regulates the ballast discharge. In this way, an adjustable amount of ballast is deposited on the track 4 on both sides of each rail 22. In an alternative embodiment, the ballast distribution device 26 is a belt which can be pivoted about an approximately vertical axis. A free end of the conveyor belt is pivoted back and forth in labor input and drops the ballast 2 on both sides of the rails 22.

By means of a diverting device 27, the ballast 2 can be diverted onto a transverse conveyor belt 28. This makes it possible, the of the Bettungsflanken 8 deposited gravel 2 deposited at a desired location laterally next to the track 4. The direction of the cross conveyor belt 28 determines the deposition side. By a Querversteilbarkeit of

Cross conveyor belts 28 and a variable belt speed can also be the distance of the discharge point to the rails 22 are varied.

[34] To supply the driven devices 9, 21, 26, 28, a power module 29 is preferably arranged on the machine 2. These are e.g. an internal combustion engine with a generator and / or a hydraulic pump. A fuel tank 30 is optionally without influence on the upper contour lines 10 of the machine 1 in the front region on the

Bottom of the frame 18 is arranged. Another drive variant is an electrically powered hydraulic unit (hydraulic power pack), which is arranged on the machine, wherein an accumulator can be provided as an energy buffer. The ballast receiving devices 9, treadmills 21, 28 and other means are electrically or hydraulically

driven. In this case, a supply by the coupled rail vehicle 5 is possible.

[35] Figures 2 and 3 show another expression of the machine 1 in a working position and in a non-working position. The longitudinal conveyor belt 21 is designed to be adjustable in height in order to convey the ballast 2 in working operation into a collecting hopper 31, to which a ballast silo 32

connected. The intermediate storage in the ballast silo 32 allows a better distribution of the ballast 2 over a longer track distance.

[36] Alternatively, the ballast 2 from the ballast silo 32 over

Schotterverteileinrichtungen 26 on both sides of each rail 22 or via a cross conveyor 28 laterally of the track 4 deposited. Both the

Gravel receiving devices 9 so also the ballast distribution devices 26 and the longitudinal conveyor belt 21 are by means of drives 20 in a

Out of work position convertible, as shown in Fig. 3.

[37] In this case, the longitudinal conveyor belt 21 is lowered so far that the contour lines 10 extend below the boundary plane 1 1. But also in the

Working operation projects the longitudinal conveyor belt 21 only slightly above the boundary plane 1 1, so from the cab 16 from at least one straight view 33 forward continues unrestricted possible. With this foresight, a low-speed operation is easily possible.

[38] In an advanced embodiment, a camera 34 is arranged at the front end of the machine 1, the images of which are displayed in real time in the driver's cab 16. This provides an additional safety device for working operation.

[39] In FIGS. 4 and 5, cross-sections of the machine 1 are shown. Fig. 4 shows the effected by means of the ballast receiving means 9, in

Essentially uphill gravel flow 35 from the

Bettungsflanken 8 up to a lower end of the longitudinal conveyor belt 21. This promotes the ballast 2 to the rear of the collecting hopper 31st

[40] Fig. 5 shows the further, substantially downwardly extending

Gravel flow 36 from the upper end of the longitudinal conveyor belt 21, via the collecting hopper 31 and optionally the ballast silo 32 to the

Ballast distribution devices 26. By means of a diverting device 27, the ballast flow can be partially or completely diverted onto the transverse conveyor belt 28 and thrown off the track 4.

[41] In order to avoid obstacles located next to the track 4, each ballast receiving device 9 can be pivoted about a pivot axis 37 by means of a pivot drive 38. In this case, the pivot axis 37 is adjusted before starting work to profile the associated Bettungsflanke 8 with a predetermined Bettungsflankenwinkel ß. For this purpose, a carrier with end brackets for supporting the auger 23 is arranged at the respective ballast receiving device 9 behind the plow blade 25. The carrier is attached to adjust the pivot axis 37 via a cardan joint on the associated suspension device 19.

Concretely, the pivot axis 37 by means of auxiliary drives orthogonal to

associated Bettungsflanke 8 furnished. When panning around the

Swivel axis 37 thus remains the set Bettungsflankenwinkel ß obtained, creating a simple control to evade

Obstacles is given. As a rule, the Gravel receiving devices 9 guided exactly over a planning protection layer 39 located below the ballast bed.

The machine 1 is preferably controlled by the driver's cab 16 of the coupled rail vehicle 5. For this purpose, the machine 1 comprises a machine controller 40, which is set up for data exchange with a controller 41 of the rail vehicle 5. In this case, an operator 42 in the driver's cab 16 via control elements trigger control commands and make adjustments to the machine 1. An automated ballast distribution can also be provided.
