BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a machine frame supported on a rail traveling wheel mechanism, and the machine frame has a height-adjustable scraping work unit and a rotatable sweeping member. The present invention relates to a ballast scraping and leveling machine of a type in which a ballast sweeper is connected and a suction nozzle connected to a suction device is arranged in the ballast sweeper.

[0002]

2. Description of the Related Art For example, European Patent Application Publication No. 041842
A ballast leveling machine capable of running on rails of the above-mentioned type, which is known from the specification of No. 8, gives the ballast bed of the track a desired cross-sectional shape and a cross-sectional shape in conformity with railway regulations, or the ballast bed. In order to restore the cross-sectional shape and thus to form the preconditions for a durable track condition, either during or subsequent to a track task, such as a roadbed tamping and track leveling task. used. In this case, the ballast newly inserted into the roadbed for the purpose of filling the inter-sleeper section with ballast or the excess ballast scattered in various places in the inter-sleeper section is removed by the height-adjustable scraping work unit. It is scraped and distributed in the cross section of the track. The ballast sweeper, which is arranged in the machine frame behind the scraping work unit when viewed in the working direction, has a track top surface that can be rotated by a rotatable sweeping member to remove excess ballast accumulated on the sleeper top surface or the road bed top surface. Used to sweep away. This excess ballast is blown off onto the conveying device via 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 the dust is generated. The device supplies dust-laden air to the filter device via a high power suction blower. When a ballast scraping and leveling machine is used in a track where conductors are attached to the upper surface of the sleepers at the center of the track or other so-called "forced track area", the ballast to be removed by a known ballast scraping and leveling machine of this type. Cannot be completely recovered. This is because it is impossible for the sweeping member to capture the ballast residuals located under the conductor for each line between the sleepers.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve the known ballast scraping and leveling machine so that even the ballast located in the lower region of the conductor by route can be removed.

[0004]

In order to solve the above-mentioned problems, the construction means of the present invention is such that the suction nozzle is placed behind the sweeping member when viewed in the working direction of the ballast scraping and leveling machine, and the conductors for each line are arranged. In order to suck out the ballast of the area, it is arranged at the midpoint of the extension length of the sweeping member when viewed in the lateral direction at right angles to the machine longitudinal direction, and the suction nozzle is a ballast sweeper by its own drive device. Is that the height can be adjusted independently.

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

[0006]

By arranging the suction nozzle with respect to the sweeping member as in the present invention, leakage of the ballast ballast surface of the track following, for example, road bed compaction work, track misalignment adjustment work, or ballast scraping work. No final processing is possible. Even in the inaccessible areas of the sweeping member, for example in the lower areas of the line conductors, the residual ballast can now be easily recovered or sucked out by the suction nozzle.
It is possible to eliminate the high work cost conventionally required for ballast removal in this area. By adjusting the suction nozzle so that the height can be adjusted independently of the ballast sweeper and that it can slide laterally, it is possible to make it possible to cover all parts of the track (and when the part is partially covered by obstacles). (Even) it will be possible to access without any problems. In this case, the laterally adjustable construction of the suction nozzle is particularly advantageous when the line conductors do not extend completely linearly. Based on the fact that the suction nozzle is placed on the unique guide frame that can travel along the track, a reliable guide is guaranteed at the work site, and the suction nozzle can be adjusted in the longitudinal direction of the guide frame. Therefore, 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, it is possible to further promote the work progress.

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 shut off in order to empty or replace the container. Inconvenient situations such as having to be done can be avoided. Therefore, the sucked-in ballast is easily separated by gravity through the rotating lock gate chamber continuously in the lower region of the ballast lock gate mechanism, and then transferred by the transfer device and stored in the ballast reservoir as needed. Or it is refilled into the track bed via the outlet if necessary. In that case, the carry 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.

Ballast Scraping Machine 1 at Work Site
In order to even out the ballast bed surface as evenly as possible,
The scraping / working unit 11 is lowered by the drive device 10 and continuously travels along the track 6. The ballast remaining on the sleepers 5 or the ballast excess remaining in the section between sleepers is placed on the transfer device 16 via the guide plate 15 by the sweeping member 14 of the ballast sweeper 12 and stored in the ballast storage device 18. Transported to
The ballast from the ballast storage device is charged into the track 6 again through the discharge port 19 as needed for compensation. When the line-specific conductor 28 is present, the guide frame 29 is lowered together with the suction nozzle 25 via the height adjusting drive device 34, the flanged wheel 33 is mounted on the rail 4, and the suction device 20 and the ballast lock are provided. The rotary drive device 23 of the gate mechanism 21 is operated. The drives 34 and 37 are pressureless controlled and guided to enable the suction nozzle 25 to be lowered by the drive 32 for use in the sleeper compartment during continuous advancement of the ballast scraping machine 1. The frame 29 is clamped 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 the drive 37, and thus the guide frame 29 via the sleeper sensor 38 is used for ballast suction. You can re-descent in the next sleeper section (see the double arrow at the bottom left of Figure 1).

The ballast sucked through the suction hose 24 enters into the lock gate chamber 40, which is located just at the uppermost position of the ballast lock gate mechanism 21, and rotates the ballast lock gate mechanism about the axis 22.
