Abstract

The invention relates to a method for correcting a track bed consisting in backfilling said track (8) in such a way that it is placed in provisionally theoretical position, in subsequently controllingly lowering said track in a final theoretical position in the frame of said track stabilisation by applying a vertically acting load to which vibrations are integrated. Gravel (19) is distributed by means of a rotatable sweeping brush (14) in order to obtain a desired homogenous ballasting of the track (8). The gravel (19) arranged in the slipper intermediary area is tamped by the action of the load and vibrations along different operations after the track stabilisation and after the sweeping brush (14) passage. Said final tamping of the gravel surface makes it possible to prevent gravel projections generated by high speeds of a train.

本発明は、請求項１の上位概念に記載の軌道位置修正方法ならびに軌道構造機械に関する。   The present invention relates to a track position correcting method and a track structure machine according to the superordinate concept of claim 1.

このような方法は、米国特許第５１７２６３７号明細書、米国特許第５１７２６３５号明細書または米国特許第４９５３４６７号明細書から公知であり、この場合ブラシは、作業方向に関して安定化装置の前後に配置されている。   Such a method is known from U.S. Pat. No. 5,172,637, U.S. Pat. No. 5,172,635 or U.S. Pat. No. 4,953,467, in which the brush is arranged before and after the stabilizing device with respect to the working direction. ing.

本発明の課題は、冒頭で述べたような方法を改良して、高い車両速度に起因する、バラスト砂利の持ち上がりを確実に防止できる方法を提供することである。   The object of the present invention is to improve the method as described at the outset and provide a method that can reliably prevent the lifting of ballast gravel due to high vehicle speed.

この課題を解決するための本発明の方法によれば、様々な作業過程の時間経過に関して、軌道安定化後でもブラシ投入後でも、まくらぎ中間域に存在するバラストを、荷重および振動に関して締め固めする。   According to the method of the present invention for solving this problem, the ballast existing in the intermediate range of the sleeper is compacted with respect to load and vibration with respect to the passage of time of various work processes, both after the track is stabilized and after the brush is charged. To do.

軌道のこのような処理を終了する表面締め固めによって、バラスト表面のいわばシーリングが達成される。これによって高速走行する車両の吸引作用によって引き起こされるバラスト飛散を回避することができる。   The so-called sealing of the ballast surface is achieved by surface compaction that terminates such treatment of the track. As a result, ballast scattering caused by the suction action of the vehicle traveling at high speed can be avoided.

本発明の別の課題は、請求項４の上位概念に記載の形式の軌道構造機械を改良して、高速走行する車両の吸引作用によって引き起こされるバラスト飛散を簡単な形式で回避することのできるものを提供することである。   Another object of the present invention is to improve the track structure machine of the type described in the superordinate concept of claim 4 and to avoid ballast scattering caused by the suction action of a vehicle traveling at high speed in a simple form.

この課題は、請求項４の特徴部に記載の構成によって解決される。   This problem is solved by the configuration described in the characterizing portion of claim 4.

ブラシの投入と安定化装置の投入とによって新たに配置された、したがって表面にソフトに載置されたバラスト砂利は、後方の機械端部に位置決めされたまくらぎ域締め固め装置によって、締め固められた表面を形成して比較的強固に固定される。したがって不都合なバラスト飛散は、ほとんど排除することができる。   The newly placed ballast gravel, placed softly on the surface with the introduction of the brush and the stabilization device, is compacted by the sleeper compaction device positioned at the rear machine end. It forms a solid surface and is fixed relatively firmly. Therefore, inconvenient ballast scattering can be almost eliminated.

本発明の別の利点は、従属請求項および図面から明らかである。   Further advantages of the invention are evident from the dependent claims and the drawings.

次に図面につき本発明の実施例を詳しく説明する。   Embodiments of the present invention will now be described in detail with reference to the drawings.

図１に示した、軌道位置修正のための軌道構造機械１は、作業方向２に関して、前方に位置する第１の機械フレーム３と後続の第２の機械フレーム４とを備えており、これらの機械フレーム３，４は、レール走行機構５によって、まくらぎ６とレール７とから形成された軌道８上を走行可能である。前方の機械フレーム３には、駆動装置９によって高さ調節可能で、かつ振動可能な安定化装置１０ならびにサイドプラウ（Flankenpfluege；フランクプラウ）１１が設けられている。   The track structure machine 1 for correcting the track position shown in FIG. 1 includes a first machine frame 3 and a subsequent second machine frame 4 which are positioned forward in the working direction 2. The machine frames 3 and 4 can travel on a track 8 formed by the sleeper 6 and the rail 7 by the rail travel mechanism 5. The front machine frame 3 is provided with a stabilization device 10 that can be adjusted in height by a drive device 9 and that can vibrate, and a side plow (Flankenpfluege) 11.

両方の機械フレーム３，４を互いに枢着式に結合するフレーム継手１２の直後に、駆動装置１３によって回転可能で、かつ高さ調節可能なブラシ１４が、後方の機械フレーム４に取り付けられている。ブラシ１４の前方に、余剰のバラスト１９をバラスト道床１６の側面（フランク）に排出するための横搬送ベルト１５が配置されている。機械１の作業方向２に関して、最後位のレール走行機構５の直前に、まくらぎ６の間に存在するバラスト１９を締め固めるための、締め固め工具１７を装備したまくらぎ域締め固め装置１８が配置されている。締め固め工具１７は、工具フレーム２０と結合された２つのレール走行機構２１の間で工具フレーム２０に沿って配置されている。工具フレーム２０は、駆動装置２２（図２参照）によって、第２の機械フレーム４に対して機械縦方向で移動可能である。   Immediately after the frame joint 12 that couples both machine frames 3, 4 to each other in a pivotal manner, a brush 14, which can be rotated by a drive device 13 and is adjustable in height, is mounted on the rear machine frame 4. . A lateral conveying belt 15 for discharging excess ballast 19 to the side surface (flank) of the ballast roadbed 16 is disposed in front of the brush 14. A sleeper area compaction device 18 equipped with a compaction tool 17 for compacting a ballast 19 existing between the sleepers 6 immediately before the rearmost rail travel mechanism 5 in the working direction 2 of the machine 1 is provided. Has been placed. The compacting tool 17 is disposed along the tool frame 20 between two rail travel mechanisms 21 coupled to the tool frame 20. The tool frame 20 is movable in the machine longitudinal direction with respect to the second machine frame 4 by a driving device 22 (see FIG. 2).

図２から判るように、第２の機械フレーム４と工具フレーム２０との間に、工具フレーム２０と結合された、駆動装置２３によって伸長可能な支持装置２４が配置されている。支持装置２４は、機械フレーム４に沿って転動可能なローラ２５を備えている。締め固め工具１７は、駆動装置２６によって、高さ調節可能かつ振動可能である。相前後して配置された３つのまくらぎ中間域２７を同時に締め固めるために、３つの締め固め工具１７が相前後して配置されている。各レール走行機構２１には、独自の走行駆動装置２８が対応配置されている。   As can be seen from FIG. 2, between the second machine frame 4 and the tool frame 20, a support device 24, which is connected to the tool frame 20 and can be extended by a drive device 23, is arranged. The support device 24 includes a roller 25 that can roll along the machine frame 4. The compaction tool 17 can be adjusted in height and can be vibrated by a driving device 26. In order to simultaneously compact the three sleeper intermediate areas 27 arranged one after the other, three compacting tools 17 are arranged one after the other. Each rail travel mechanism 21 is provided with a unique travel drive device 28 corresponding thereto.

以下に、記載の軌道構造機械１を用いた軌道位置修正方法を詳しく説明する。   Below, the track position correction method using the described track structure machine 1 will be described in detail.

軌道位置修正のために、バラスト道床１６に接触する軌道８は、先ず一時的な目標位置に持ち上げて、突き固めが行われる（前置の図示していない突き固め機械によって）。次いで軌道８は、安定化装置１０の投入による軌道安定化の範囲内で、鉛直方向で作用する移動荷重および振動を及ぼして、最終的に管理下で最終的な目標位置に降下される。この場合機械１は、連続的に作業方向２で走行する。これに対して並行して、後置の回転ブラシ１４によって、軌道８上もしくはまくらぎ中間域２７に存在するバラスト１９は、軌道８の、所望の均等なバラスト分散を達成するために分配される。   In order to correct the trajectory position, the trajectory 8 in contact with the ballast road bed 16 is first lifted to a temporary target position and tamped (by a tamping machine not shown in the front). Next, the track 8 is subjected to a moving load and vibration acting in the vertical direction within the range of the track stabilization by turning on the stabilizing device 10, and finally lowered to the final target position under management. In this case, the machine 1 continuously travels in the working direction 2. In parallel to this, the ballast 19 present on the track 8 or in the sleeper intermediate zone 27 is distributed by the rear rotary brush 14 in order to achieve the desired uniform ballast distribution of the track 8. .

次いで様々な作業過程の時間経過に関して、軌道安定化後でも、またブラシ１４の投入後でも、まくらぎ中間域２７に存在するバラスト１９は、まくらぎ域締め固め装置１８によって締め固められる。このために相前後して配置された締め固め工具１７は、それぞれまくらぎ中間域２７に降下され、鉛直方向の荷重と振動との組み合わせで、短時間でバラスト１９に押圧される。この場合工具フレーム２０は、位置的に安定していて、かつこれによって、連続的に前進移動する後方の機械フレーム４に対して、最後位のレール走行機構５に向かって移動される。   The ballast 19 present in the sleeper intermediate region 27 is then compacted by the sleeper region compaction device 18 with respect to the passage of time of the various work processes, both after stabilization of the track and after the introduction of the brush 14. For this purpose, the compaction tools 17 arranged one after the other are respectively lowered to the sleeper intermediate zone 27 and pressed against the ballast 19 in a short time by a combination of vertical load and vibration. In this case, the tool frame 20 is stable in position, and is thereby moved toward the rearmost rail travel mechanism 5 with respect to the rear machine frame 4 that continuously moves forward.

所望のバラスト締め固めが達成されると、走行駆動装置２８および駆動装置２２がアクティブ化され、これによって工具フレーム２０は、先行の端部位置に迅速に移動される。適当なまくらぎ中間域２７の上方で締め固め工具１７をセンタリングしたあとで、新たな締め固めサイクルが行われる。これに対して並行して、バラスト道床１６の、まくらぎ６に隣接するまくらぎ前縁領域２９に存在するバラスト１９は、前縁締め固め装置３０によって締め固められる。   When the desired ballast compaction is achieved, the travel drive 28 and drive 22 are activated, thereby quickly moving the tool frame 20 to the previous end position. After centering the compaction tool 17 above the appropriate sleeper intermediate zone 27, a new compaction cycle is performed. In parallel to this, the ballast 19 existing in the sleeper leading edge region 29 adjacent to the sleeper 6 of the ballast road bed 16 is compacted by the leading edge compacting device 30.

そのあとで選択的に、バラスト表面のシーリング（Versiegerung；封止処理）を実現するための別の作業過程として、溶剤の蒸発により硬化する液体が、バラスト１９に吹き付けられる。   Thereafter, as another work process for realizing the sealing of the ballast surface (Versiegerung), a liquid that is hardened by evaporation of the solvent is sprayed on the ballast 19.

本発明による方法は、図３および図４に示した実施例で行うこともできる。図３に示した実施例によれば、ブラシ１４およびまくらぎ域締め固め装置１８は、独自の機械３１に設けられており、この機械３１は、安定化装置３２の後方で用いられる。図４の実施例によれば、まくらぎ域締め固め装置１８は、独自の機械３３に設けられている。   The method according to the invention can also be carried out in the embodiment shown in FIGS. According to the embodiment shown in FIG. 3, the brush 14 and the sleeper area compaction device 18 are provided in a unique machine 31, which is used behind the stabilization device 32.
