Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a track construction machine for track tracking, with a machine frame mounted on rail bogies, to which a ballast tank with discharge openings and a deflecting member are associated.

BACKGROUND OF THE INVENTION

A machine for distributing and leveling bed ballast is already known from AT 404 039 B. The machine has a machine frame mounted on the rail bogies on which the sweepers are arranged, the central and side plows and the ballast hopper with a continuous floor conveyor belt. The ballast tank has drain holes for ballasting the track. Each discharge opening is associated with a conveyor belt which is arranged immediately below it. When these conveyor belts are at rest, an effective closure of the discharge openings is provided. In order to achieve a precisely metered ballast discharge, the conveyor belts are easy to operate. Gravel filling is also possible in the switch areas, since the conveyor belts are rotatable about a vertical axis.

From AT 389 333 B a ballast truck for ballast material is known on the rail. The freight wagon has a V-shaped deflection device on its transfer conveyor belt, which directs the transport of gravel optionally via the transfer conveyor belt to a subsequent freight wagon or via discharge troughs to the rail. Emptying gravel next to the track is not possible with this construction.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide the above-mentioned track condition machine in such a way that the problem of possible gravel build-up can be solved by simple structural means.

The track construction machine for track tracking, with a machine frame mounted on rail bogies, to which a ballast tank with discharge openings and a deflecting member is associated, according to the invention, which is designed by means of a drive to be displaced from a non-operational manner a position to an operating position adapted to receive gravel below the discharge opening.

With such an arrangement, by simply adjusting the deflection member, an excessive amount of gravel that suddenly occurs during gravel filling can be thrown away next to the track or the gravel container can simply be emptied. If material for backfill of the track is again required, the deflection member is moved back to its off-position position. Again, it is again possible to feed the ballast unrestrictedly through the discharge openings into the ballast bed of the rail.

According to a preferred embodiment of the invention, the deflecting member is pivotable about a horizontal axis arranged in the transverse direction of the machine.

Preferably, the deflecting member is pivotable about a vertical axis.

According to a further variant, the deflecting member is preferably displaceable in the longitudinal direction of the machine.

The deflecting member is preferably designed as a conveyor belt.

Alternatively, the deflecting member is preferably a groove.

A particularly advantageous embodiment consists in that the machine further comprises a side plow and a central plow, between which a deflecting member is arranged.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic side view of a track construction machine with an adjustable deflection member; FIGS. 2 and 3 are side views of other exemplary embodiments of the deflection members; FIGS. 4 and 5; schematically when viewed in the machine direction, two further exemplary embodiments of the deflection members.

DETAILED DESCRIPTION OF THE INVENTION

The track construction machine 1 shown in FIG. 1 for ballast filling the track 2 essentially consists of a machine frame 4 which is mounted on rail bogies 3. In the working direction shown by the arrow 5, the machine frame 4 is arranged one after the other the following working units. These consist of a sweeping device 7 having a conveyor belt arrangement 6, a central plow 8 and a side plow 9. All these working units 7, 8, 9 are formed in height-adjustable by means of drives 10 articulated on the machine frame 4. As well as the traction drive 11, a motor 12 is provided. In the region above the central plow 8, a ballast tank 13 is provided which is arranged on the machine frame 4. This ballast tank 13 is provided in the longitudinal direction of the machine 1 for building the track 2 from the transfer end 14 The floor area of the ballast tank 13 is formed by a floor conveyor belt 16. On both ends of the track condition machine 1, traction or working cabins are arranged. 17. Depending on the working direction in the front traction or working cab 17 is an actuating device 18 for operating various working units. Immediately below the discharge opening 15, which is formed as a trough 19, a deflecting member 20 is provided. It is designed as a conveyor belt 21 and is adjustable by means of a drive 22 from a non-operational position indicated by dashed lines around the axis 23 arranged horizontally and transversely. direction of the machine 1 for the state of the track 2, to the working position. The conveyor belt 21 is driven by a drive 24 and is provided in the transverse direction of the track building machine 1.

The operation of the track construction machine 1 according to the invention is described in more detail below. Already before working, the ballast container 13 of the track building machine 1 is filled. Part of the ballast capacity is reserved for the ballast returned by the sweeper 7 to the conveyor belt arrangement 6. Upon reaching the workplace, the sweepers 7, the central plow 8 and the side plow 9 are lowered by means of drives 10 onto the track 2. The deflecting member 20 is in the off-position position.

During the continuous forward movement of the track building machine 1 in the direction of the arrow 5, the track 2 is filled with gravel and the bed is profiled. Any excess gravel is conveyed to the ballast container 13 via the sweeping device 7 and the conveyor belt arrangement 6.

In the event of a lack of gravel, gravel from the gravel container 13 can be ejected to the rail 2 via the discharge opening 15. If the gravel container 13 is full and the gravel container 7 is still receiving more gravel, the deflector 20 is moved into its working positions. Now the ballast can be ejected according to the ballast bed. Of course, the deflecting member 20 can also be used to empty the ballast container 13 after the work deployment is completed elsewhere. Once it is

The gravel is again used for the ballast bed, so that the deflecting member 20 is moved back to its off-position position.

In the embodiments shown in Figures 2 to 5, the same reference numerals as in the description of Figure 1 are used for simplicity in functionally identical parts.

In Fig. 2 there is a deflection member 20 which is movable by means of a drive 22 in the longitudinal direction of the track construction machine 1. For this purpose, the deflection member 20 has guide rollers 25 which are provided in a longitudinal guide 26 arranged on the machine frame 4. The deflecting member 20 of FIG. 3 is pivotable by a drive 22 about a vertical axis 27.

Two further exemplary embodiments in which the deflecting member 20 is formed as a groove 28 are shown in FIGS. 4 and 5. The groove 28 is each mounted in longitudinal guides 26 and can be adjusted by means of a drive 22 in the longitudinal direction of the machine 1 for construction. 4, while the groove 28 in FIG. 4 is formed in two parts to simultaneously eject ballast on both sides of the track 2, the groove 28 of FIG. 5 can additionally be adjusted. This adjustment is effected by means of drives 29 around the axis 30 provided in the longitudinal direction of the track construction machine 1. This allows the optional discharge of gravel to one of the two sides of the track 2. It is of course also possible to combine these two embodiments. By means of a two-part and adjustable groove 28, it is possible to discharge to both or to any side of the track 2.
