[Industrial applications]

 The present invention has a machine frame supported on a rail traveling wheel mechanism, to which a height-adjustable scraping leveling work unit and a ballast sweeper having a rotatable sweeping member are connected. The present invention relates to a ballast scraping and leveling machine of the type in which a suction nozzle connected to a suction device is provided in the ballast sweeper.

[0002]

[Prior art]

 For example, a rail-operable ballast scraping and leveling machine of the above-mentioned type, which has become known based on European Patent Application Publication No. 0418428, has a desired cross-sectional shape for a ballast bed of a track and a cross-sectional shape that complies with railway regulations. Or to repair the ballast bed profile and thus form the prerequisites for a durable track condition, during the course of track operations such as track tamping and track leveling operations. Or, it is used subsequent to the orbital work. In this case, the ballast newly inserted into the roadbed for the purpose of compensating the ballast between the sleepers or the ballast excess scattered in various places in the sleeper compartment is a leveling-adjustable scraping work unit. Are distributed and distributed in the cross section of the orbit. The ballast sweeper, which is arranged in the machine frame behind the leveling work unit in the working direction, is tracked by a rotatable sweeping member in order to remove excess ballast accumulated on the top of the sleepers or on the bed. Used to sweep the top of the sash. This excess ballast is blown off onto the transfer device through the inclined guide plate and is further discharged toward the shoulders of the roadbed on both sides. The suction nozzle of the suction device is fixed on the sweeper cover that shields the sweeping member in an inverted U shape in order to suppress the dust that inevitably rises due to the operation of the sweeping member at the same time as it is generated. The suction device supplies dust-containing air to the filter device via a high-output suction fan. When a ballast scraping machine is used in the track where the conductors are attached to the upper surface of the sleepers at the center of the track or other so-called "forced track area", it should be removed by a known ballast scraping machine of this type. Ballast cannot be completely recovered. This is because it is impossible for the sweeping members to capture the ballast residue located under the conductors for each line between the sleepers.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to improve the known ballast scraping and leveling machine so that even ballasts located below the line conductors can be removed.

[0004]

[Means for Solving the Problems]

 The construction means of the present invention for solving the above-mentioned problems includes a suction nozzle disposed rearward of a sweeping member when viewed in a working direction of a ballast scraping and leveling machine, and a machine for sucking out ballast in a conductor area for each line. It is arranged at the midpoint of the extension length of the sweeping member when viewed in the transverse direction at right angles to the longitudinal direction, and the suction nozzle is adjustable in height independently of the ballast sweeper by its own drive device. There is a point.

Advantageous embodiments of the invention are described in the second and subsequent claims.

[0006]

[Action]

 By arranging the suction nozzle with respect to the sweeping member as in the present invention, for example, after the ballast tamping work, the track misalignment adjustment work, or the ballast scraping work, the final ballast ballast surface of the track is not leaked. Processing becomes possible. Even in the inaccessible areas of the sweeping member, e.g. in the lower areas of the line conductors, residual ballast can now be easily recovered or sucked out by suction nozzles, which is conventionally required for ballast removal in this area. It is possible to save the expensive work cost that was said to be. The height of the ballast sweeper can be adjusted independently of the ballast sweeper, and the suction nozzle is configured to be slidable in the lateral direction, so that all parts of the track (and those parts are partially covered by obstacles) (Even) will be accessible without any problems. In this case, the laterally adjustable construction of the suction nozzle is particularly advantageous when the line conductors do not extend perfectly in a straight line. By arranging the suction nozzle on a unique guide frame that can travel along the track, a reliable guide at the work site is guaranteed, and the suction nozzle can be adjusted in the longitudinal direction of the guide frame. Based on this, it becomes possible to obtain a desired uniform ballast surface while continuously operating the ballast scraping and leveling machine. Independently of this, in this case, the guide frame can be moved step by step from one sleeper compartment to the next sleeper compartment via the sleeper sensor. In this connection, by constructing the suction nozzle so as to be rotatable about an axis extending in the machine longitudinal direction, there is an advantage that the work progress can be further assisted.

Due to the presence of the ballast lock gate mechanism arranged in the suction device, when the container in the suction area of the suction device is totally filled with ballast, the suction device is used to empty or replace the container. Inconvenient situations such as having to shut off can be avoided. Therefore, the sucked-in ballast is easily separated by gravity through the rotating rock gate chamber continuously in the lower area of the ballast lock gate mechanism, then transferred by the transfer device and, if necessary, to the ballast reservoir. It can be stored or, if necessary, refilled into the track bed via the outlet. In that case, the transport amount can be controlled by the rotation speed of the rotating ballast lock gate mechanism. The oblique orientation of the ballast lock gate mechanism significantly facilitates and facilitates ballast delivery to the carrier.

As can be seen from the detailed configuration diagram of the suction nozzle 25 shown in FIG. 2, the suction nozzle is arranged behind the sweeping member 14 in the working direction of the ballast scraping and leveling machine 1 and, at the same time, in the machine longitudinal direction. It is located in the center of the length of the sweeping member extending in a lateral direction at right angles to, so that the ballast can be sucked from the lower section of the conductor 28 for each line. The conductor 28 for each line is fixed to the upper surface of the sleeper 5 substantially in the middle between the rails 4 and extends in the longitudinal direction of the track as is customary. The suction nozzle 25 is rotatably supported on a guide frame 29 via a holder 30 for adjusting the height independently of the ballast sweeper 12 about an axis 31 extending in the machine longitudinal direction. In this case, the holder 30 is connected to a drive device 32 pivotally mounted on the guide frame 29. In this way, the suction nozzle 25 is positioned above the sleeper plane defined by the upper surface of the sleeper, from a non-operating position (position indicated by a chain line), and partially below the sleeper plane. The height can be adjusted to the suction operation position located at.

The guide frame 29 can roll along the track 6 via the flanged wheels 33, and is pivotally attached to the machine frame 2 by a height adjusting drive device 34. The drive allows the guide frame 29 to be lifted from the track 6 to stop operation. The clamping jaws 36, which cooperate with the flanged wheels 33 and can be loaded via the drive 35, guide the guide frame 29 to the track 6 for a short time in the suction nozzle operating position between the two sleepers 5 when the suction nozzle 25 descends. Used to lock in place during. Furthermore, the guide frame 29 is constructed so that it can be adjusted relative to the machine frame 2 in the machine longitudinal direction by a drive device 37 pivotally attached to the machine frame 2, and is a sleeper fixed to the lower surface thereof. The sleeper sensor is provided to detect the position of the sleeper 5 with respect to the guide frame 29 in a contactless manner.

As can be seen from FIG. 3, the ballast lock gate mechanism 21 is composed of a drum-shaped casing 39, and inside the drum-shaped casing, six lock gate chambers 40 rotatable about an axis 22 are arranged. ing. The rotary drive device 23 is coaxially mounted on the end face of the ballast lock gate mechanism 21 located on the side opposite to the suction hose 24, and the ballast outlet 26 is provided at the deepest part of the ballast lock gate mechanism. It is arranged. Both the connection part of the suction hose 24 and the suction device 20 are provided in the upper region of the ballast lock gate mechanism 21. The ballast lock gate mechanism 21 may also cooperate with another suction nozzle or another type of suction nozzle that captures or covers the entire lateral extent of the ballast bed, for example instead of the suction nozzle 25 for the central area of the ballast bed. .

At the work site, the ballast leveling machine 1 lowers the leveling work unit 11 by the drive device 10 and runs continuously along the track 6 in order to level the ballast bed surface as evenly as possible. . The ballast remaining on the sleepers 5 or the ballast excess remaining in the sleeper inter-compartment is placed on the transfer device 16 via the guide plate 15 by the sweeping member 14 of the ballast sweeper 12 to be stored in the ballast storage device. The ballast is transported to the inside of the ballast 18, and the ballast from the ballast storage device is loaded into the track 6 again through the discharge port 19 as needed for the filling. When the line-specific conductor 28 is present, the guide frame 29 is lowered together with the suction nozzle 25 through the height adjusting drive device 34, the flanged wheel 33 is placed on the rail 4, and the suction device 20 and the ballast are provided. The rotary drive device 23 of the lock gate mechanism 21 is operated. In order to allow the suction nozzle 25 to be lowered by the drive 32 for use in the sleeper compartment during the continuous advancement of the ballast leveling machine 1, the drives 34 and 37 are pressureless controlled and The guide frame 29 is fastened to the rail 4 for a short time by the drive device 35 and the clamp jaws 36. After lifting the suction nozzle 25 again, the guide frame 29 is advanced more quickly than the machine frame 2 in the working direction by means of the drive 37, and thus the guide frame 29 via the sleeper sensor 38 is used for ballast wicking. It is possible to re-drop in the next sleeper section (see the double arrow in the lower left of Fig. 1).

The ballast sucked through the suction hose 24 enters the lock gate chamber 40 located at the just uppermost position of the ballast lock gate mechanism 21, and the rotation of the ballast lock gate mechanism about the axis 22 is performed. By the action of gravity, the ballast is brought to the ballast outlet 26, from which the ballast is conveyed via the trough 27 and the conveying device 16 into the ballast storage device 18 where it is stored.

In the variant embodiment shown in FIG. 4, the guide frame 41 is pivotally attached to the machine frame 43 of the ballast scraping and leveling machine 44 via a height adjusting drive 42 and via flanged wheels 45. It is possible to roll along the track 46. In order to absorb the ballast from the lower area of the conductor 47 for each line extending in the longitudinal direction of the track, the suction nozzle 48 is arranged at the center of the track above the conductor 47 for each line and via the suction hose 49. It is connected to a suction device (not shown). The suction nozzle 48 is supported by the drive device 50 so as to be able to slide laterally along the guide frame 41, and is also height-adjustably supported by another drive device 51, and therefore the condition of the track 46. And the position of the conductor 47 for each route. The sleeper sensor 52 and the rail clamp device 53 are used to position the guide frame 41 at the work site, and the process of positioning the guide frame is substantially the same as that of the above-described embodiment of the present invention.
