Definitions

  • the invention relates to a tamping machine for compacting the ballast bedding of a track with two rails, with tamping units for tamping under the track, with a main lifting device with lifting cylinders and roller tongs for leveling and straightening the two rails, arranged between drives, preferably in front of the tamping units of the track and with an additional lifting device for leveling and straightening a track branching off from the track in the area of a switch.
  • the additional lifting device is used to lift a track branching off from the main track in a switch.
  • Track tamping machines are machines that correct the position of tracks and switches. For this purpose, measuring systems are used that measure the actual track height and actual position of the track direction as well as the actual elevation of the track during work and compare them with specified target values. With the help of a lifting and straightening device, the track grid is raised and laterally aligned until the difference between the specified target position and the actual position is zero. This geometric position is fixed by compressing the ballast under the sleepers with the help of a tamping unit. The track grating is lifted and straightened using appropriate hydraulic lifting and straightening cylinders with proportional or servo controls. Turnouts have a continuous track and a branching track as a special feature.
  • Another mobile track tamping machine with a device for lifting and straightening a track is from the AT 356 165 A known, with which all track components in switch areas can be recorded.
  • the lifting tool can be used to selectively grasp the head or foot of the rail or a component of the main track or the branch track.

  • the additional lifting straightening device comprises a telescopic support arm, which has a rail mount with guide roller and roller tongs at one end and which is rotatably mounted on the main lifting straightening device at the other end about an axis parallel to the tamping machine's longitudinal axis, with adjustment of the pivot angle of the support arm with respect to the main lifting device, a lifting drive is provided.
  • the support arms of the additional lifting device are not hinged directly to the machine frame, away from the main lifting points of application, as provided in the prior art, but are mechanically connected directly to the main lifting device, whereby the additional lifting device is designed to be pivotable about the tamping machine's longitudinal axis, practically as a single-armed, telescopic lever . Since the additional lifting device is mechanically connected to the main lifting device, a controlled, even and torsion-free lifting can take place.
  • the two lifting points of the main lifting device on the main track as well as the lifting point of the additional lifting device in the branch track must lie in one plane in order to prevent twisting of the turnout or an imprecise geometric placement of the same. This can be done with the lifting drive of the additional lifting device, which lifts the branch track into the level of the main track. Main and branch tracks are thus set up together on one level with the lifting drives of the main and additional lifting devices.
  • Another advantage of the invention is that the support arm lies horizontally parallel to the level of the switch and thus the guide roller of the additional lifting device is normally placed on the branching rail in the switch and the force application point of the roller tongs of the additional lifting device is optimally located, which prevents the roller tong from slipping during operation can.
  • the additional lifting device preferably comprises two telescopic support arms, one being assigned to a track branching off to the right in the area of a switch from the track and the other being assignable to a track branching off to the left of the track in the area of a switch.

  • the additional lifting device can be shifted along with the main lifting device in the longitudinal direction of the track, so that this shifting device can also be used to select a more favorable point of application for the roller tong (e.g. because a shock at the current point in the junction prevents the roller tong from closing).
  • a displacement sensor is assigned to the displacement drive of the main lifting device and the additional lifting device, if the main lifting device and thus the additional lifting device is assigned a second shifting drive and if the main lifting device is synchronized with the shifting drive by means of a control or regulation system can be displaced in the longitudinal direction of the tamping machine, which always ensures optimal vertical power transmission and undesirable force components in the longitudinal direction of the track can be avoided.
  • the pivot points of the lifting drives on the main frame are shifted synchronously.
  • a distance sensor is provided to determine the height difference between the main lifting device and the support arm of the additional lifting device, the support arm with the associated lifting drive being displaceable into the main lifting plane of the main lifting device. With the aid of the distance sensor, the height difference between the main lifting device and the support arm of the additional lifting device is measured.

Description

Die Erfindung bezieht sich auf eine Stopfmaschine zum Verdichten der Schotterbettung eines Gleises mit zwei Schienen, mit Stopfaggregaten zum Unterstopfen des Gleises, mit einer zwischen Laufwerken, in Arbeitsrichtung vorzugsweise vor den Stopfaggregaten, angeordneten Hauptheberichteinrichtung mit Hebezylindern und mit Rollzangen zum Nivellieren und Richten der zwei Schienen des Gleises und mit einer Zusatzheberichteinrichtung zum Nivellieren und Richten eines vom Gleis abzweigenden Gleises im Bereich einer Weiche. Die Zusatzhebeeinrichtung dient zum Anheben eines vom Hauptgleis abzweigenden Gleisstranges in einer Weiche.The invention relates to a tamping machine for compacting the ballast bedding of a track with two rails, with tamping units for tamping under the track, with a main lifting device with lifting cylinders and roller tongs for leveling and straightening the two rails, arranged between drives, preferably in front of the tamping units of the track and with an additional lifting device for leveling and straightening a track branching off from the track in the area of a switch. The additional lifting device is used to lift a track branching off from the main track in a switch.

Eine derartige Stopfmaschine ist aus der RU 2338823 C bekannt. Gleisstopfmaschinen sind Maschinen welche die Gleislage von Gleisen und Weichen berichtigen. Dazu werden Messsysteme benutzt die die Gleishöhen-Istlage und die Gleisrichtungs-Istlage sowie die Überhöhungs-Istlage des Gleises während der Arbeit messen und mit vorgegebenen Sollwerten vergleichen. Mit Hilfe einer Hebe-Richteinrichtung wird der Gleisrost solange angehoben und seitlich ausgerichtet bis die Differenz zwischen vorgegebener Soll-Lage und Ist-Lage Null ist. Diese geometrische Lage wird durch Verdichten des Schotters unter den Schwellen mit Hilfe eines Stopfaggregates fixiert. Das Heben und Richten des Gleisrostes erfolgt dabei über entsprechende hydraulische Hebe- und Richtzylinder mit Proportional- oder Servosteuerung. Weichen weisen als Besonderheit ein durchgehendes Gleis und ein abzweigendes Gleis auf. Übliche Weichenstopf- oder Universalmaschinen weisen ein Zusatzhebeaggregat auf, welches an einem dritten Punkt der Weiche im abzweigenden Gleis mithebt. EP 0 314 854 B1 zeigt eine Ausführung bei der diese Zusatzhebeeinrichtung über einen quer ausfahrbaren Tragarm mit Seilrolle und Seilzug und Gleiszange positioniert wird. DE 43 07 862 A1 zeigt eine andere übliche Ausführung dieser Zusatzhebeeinrichtung mit einem Tragarm, Rollzange und Führungsrolle. Allen diesen Ausführungen ist gemeinsam, dass die Position dieser Zusatzhebeeinrichtung in Arbeitsrichtung deutlich vor der Haupthebeeinrichtung liegt und dass diese am Maschinenrahmen entfernt von der Haupthebeeinrichtung befestigt ist. Damit ergibt sich das Problem, dass die Zusatzhebeeinrichtung die Weiche beim Heben verwindend beansprucht und dass die ebene Lage der Weiche durch das Unterstopfen nicht gegeben ist. Zudem gibt es Weichen bei der die Langschwellen unterteilt sind. Die Langschwellenteile werden bei diesen Weichen gelenkig Abstand haltend miteinander verbunden. Bei dieser Art von Weichen ergibt sich ein unkontrolliertes Anheben des abzweigenden Weichenstranges durch Zusatzhebeeinrichtungen der oben geschilderten Art. Um dies zur vermeiden wurde in EP 1 162 310 B1 eine verbindende, teleskopisch in Maschinenquerrichtung verlängerbare mechanische Messvorrichtung mit Messwertgeber erfunden. EP 1 143 069 B1 zeigt eine ähnliche Ausführung bei der die mechanische Vorrichtung durch eine Laserebene mit Rundumlaser und Empfangseinrichtung auf der Zusatzhebeeinrichtung ersetzt wurde. Hebeantriebe sowie Verschiebeantriebe werden bei Gleisstopfmaschinen häufig über Hydraulikzylinder ausgeführt. Bekannt sind Ausführungsarten bei denen die Wegmessung in den Hydraulikzylinder integriert ist.Such a tamping machine is from RU 2338823 C known. Track tamping machines are machines that correct the position of tracks and switches. For this purpose, measuring systems are used that measure the actual track height and actual position of the track direction as well as the actual elevation of the track during work and compare them with specified target values. With the help of a lifting and straightening device, the track grid is raised and laterally aligned until the difference between the specified target position and the actual position is zero. This geometric position is fixed by compressing the ballast under the sleepers with the help of a tamping unit. The track grating is lifted and straightened using appropriate hydraulic lifting and straightening cylinders with proportional or servo controls. Turnouts have a continuous track and a branching track as a special feature. Conventional switch tamping or universal machines have an additional lifting unit, which lifts at a third point of the switch in the branching track. EP 0 314 854 B1 shows an embodiment in which this additional lifting device is positioned via a transversely extendable support arm with rope pulley and cable and track clamp. DE 43 07 862 A1 shows another conventional design of this additional lifting device with a support arm, roller pliers and guide roller. All of these embodiments have in common that the position of this additional lifting device is clearly in front of the main lifting device in the working direction and that it is attached to the machine frame at a distance from the main lifting device. This results in the problem that the additional lifting device stresses the switch in a twisting manner during lifting and that the level position of the switch is not given by the tamping. There are also turnouts in which the long sleepers are divided. The long sleeper parts are connected to one another in an articulated manner keeping a distance. With this type of switch, there is an uncontrolled lifting of the branching switch line by additional lifting devices of the type described above. To avoid this, in EP 1 162 310 B1 invented a connecting mechanical measuring device with a transducer that can be extended telescopically in the cross machine direction. EP 1 143 069 B1 shows a similar design in which the mechanical device has been replaced by a laser plane with an all-round laser and receiving device on the additional lifting device. In track tamping machines, lifting drives and shifting drives are often implemented using hydraulic cylinders. Designs are known in which the displacement measurement is integrated into the hydraulic cylinder.

Eine weitere fahrbare Gleisstopfmaschine mit einer Vorrichtung zum Heben und Richten eines Gleises ist aus der AT 356 165 A bekannt, mit der auch alle Gleisbauteile in Weichenbereichen erfaßt werden können. Dies wird dadurch erreicht, daß mit dem Hebewerkzeug ein wahlweises Erfassen des Schienenkopfes bzw. -fußes oder eines Bauteiles des Hauptgleises oder des Abzweiggleises möglich ist. Insbesondere greift im Bereich einer Weiche also ein Hebewerkzeug eine Schiene des Hauptgleises und das andere Hebewerkzeug anstelle der anderen Schiene des Hauptgleises eine Schiene des Abzweiggleises. Der Erfindung liegt somit die Aufgabe zugrunde, eine Stopfmaschine anzugeben, mit der eine Weiche mit einfachen Mitteln praktisch verwindungsfrei gehoben werden kann. Ein unkontrolliertes Anheben des abzweigenden Weichenstranges durch Zusatzhebeeinrichtungen soll vermieden werden.Another mobile track tamping machine with a device for lifting and straightening a track is from the AT 356 165 A known, with which all track components in switch areas can be recorded. This is achieved in that the lifting tool can be used to selectively grasp the head or foot of the rail or a component of the main track or the branch track. In particular, in the area of a switch, a lifting tool grips a rail of the main track and the other lifting tool grips a rail of the branch track instead of the other rail of the main track. The invention is thus based on the object of specifying a tamping machine with which a switch can be lifted practically torsion-free with simple means. An uncontrolled lifting of the branching turnout line by additional lifting devices should be avoided.

Die Erfindung löst die gestellte Aufgabe durch eine Stopfmaschine nach dem Anspruch 1, wobei die Zusatzheberichteinrichtung einen teleskopierbaren Tragarm umfasst, der einerends eine Schienenaufnahme mit Führungsrolle und Rollzange aufweist und der andernends um eine zur Stopfmaschinenlängsachse parallele Achse drehbar an der Hauptheberichteinrichtung gelagert ist, wobei zur Einstellung des Schwenkwinkels des Tragarms gegenüber der Hauptheberichteinrichtung ein Hebeantrieb vorgesehen ist.The invention solves the problem posed by a tamping machine according to claim 1, wherein the additional lifting straightening device comprises a telescopic support arm, which has a rail mount with guide roller and roller tongs at one end and which is rotatably mounted on the main lifting straightening device at the other end about an axis parallel to the tamping machine's longitudinal axis, with adjustment of the pivot angle of the support arm with respect to the main lifting device, a lifting drive is provided.

Die Tragarme der Zusatzhebeeinrichtung sind erfindungsgemäß nicht, wie im Stand der Technik vorgesehen direkt am Maschinenrahmen, entfernt von den Haupthebeangriffspunkten, angelenkt, sondern mechanisch direkt mit der Haupthebeeinrichtung verbunden, wobei die Zusatzhebeeinrichtung um die Stopfmaschinenlängsachse schwenkbar, praktisch als einarmiger, teleskopierbarer Hebel, ausgeführt wird. Da die Zusatzhebeeinrichtung mit der Haupthebeeinrichtung mechanisch verbunden ist, kann eine kontrollierte, gleichmäßige und verwindungsfreie Anhebung erfolgen. Die zwei Hebeangriffspunkte der Hauptheberichteinrichtung am Stammgleis sowie der Hebeangriffspunkt der Zusatzheberichteinrichtung im Abzweiggleis müssen in einer Ebene liegen, um eine Verwindung der Weiche oder eine ungenaue geometrische Ablage derselben zu verhindern. Dies kann mit dem Hebeantrieb der Zusatzheberichteinrichtung bewerkstelligt werden, der das Abzweiggleis in die Ebene des Stammgleises hebt. Stamm- und Abzweiggleis werden somit gemeinsam in einer Ebene mit den Hebeantrieben von Haupt- und Zusatzheberichteinrichtung eingerichtet.According to the invention, the support arms of the additional lifting device are not hinged directly to the machine frame, away from the main lifting points of application, as provided in the prior art, but are mechanically connected directly to the main lifting device, whereby the additional lifting device is designed to be pivotable about the tamping machine's longitudinal axis, practically as a single-armed, telescopic lever . Since the additional lifting device is mechanically connected to the main lifting device, a controlled, even and torsion-free lifting can take place. The two lifting points of the main lifting device on the main track as well as the lifting point of the additional lifting device in the branch track must lie in one plane in order to prevent twisting of the turnout or an imprecise geometric placement of the same. This can be done with the lifting drive of the additional lifting device, which lifts the branch track into the level of the main track. Main and branch tracks are thus set up together on one level with the lifting drives of the main and additional lifting devices.

Da sich die Zusatzhebeeinrichtung in unmittelbarer Nähe der Hebeangriffspunkte der Haupthebeeinrichtung befindet wird eine Verwindung der Weiche beim Heben verhindert. Ein weiterer Vorteil der Erfindung ist, dass der Tragarm horizontal parallel zur Weichenebene liegt und damit die Führungsrolle der Zusatzhebeeinrichtung normal auf die abzweigende Schiene in der Weiche aufsetzt und der Kraftangriffspunkt der Rollzange der Zusatzhebeeinrichtung somit optimal liegt, womit ein Abrutschen der Rollzange im Betrieb vermieden werden kann.Since the additional lifting device is in the immediate vicinity of the lifting attachment points of the main lifting device twisting of the switch during lifting is prevented. Another advantage of the invention is that the support arm lies horizontally parallel to the level of the switch and thus the guide roller of the additional lifting device is normally placed on the branching rail in the switch and the force application point of the roller tongs of the additional lifting device is optimally located, which prevents the roller tong from slipping during operation can.

Die Zusatzheberichteinrichtung umfasst vorzugsweise zwei teleskopierbare Tragarme, wobei einer in Arbeitsrichtung gesehen einem im Bereich einer Weiche vom Gleis rechts abzweigenden Gleis und der andere einem im Bereich einer Weiche vom Gleis links abzweigenden Gleis zuordenbar ist. Damit können Abzweiggleise vom Stammgleis nach rechts gleichermaßen wie Abzweiggleise vom Stammgleis nach links gehoben werden.The additional lifting device preferably comprises two telescopic support arms, one being assigned to a track branching off to the right in the area of a switch from the track and the other being assignable to a track branching off to the left of the track in the area of a switch. This means that branch tracks can be lifted to the right from the main track in the same way as branch tracks from the main track to the left.

Erfindungsgemäß sind der Hauptheberichteinrichtung zugeordnete Hebeantriebe und der Zusatzheberichteinrichtung zugeordnete Hebeantriebe über einen Verschiebeantrieb in Stopfmaschinenlängsrichtung verschiebbar, wobei die Hebeantriebe auf einem gemeinsamen Schlitten gelagert und mit diesem in Stopfmaschinenlängsrichtung verschiebbar sind. So kann die Zusatzhebeeinrichtung mit der Hauptheberichteinrichtung in Gleislängsrichtung mitverschoben werden, wodurch diese Verschiebeeinrichtung auch dazu benutzt werden kann einen günstigeren Angriffspunkt der Rollzange zu wählen (weil z.B. ein Stoß an der aktuellen Stelle im Abzweig ein Schließen der Rollzange verhindert). In diesem Zusammenhang ist es zudem von Vorteil, wenn dem Verschiebeantrieb der Hauptheberichteinrichtung und der Zusatzheberichteinrichtung ein Wegsensor zugeordnet ist, wenn der Hauptheberichteinrichtung und damit der Zusatzheberichteinrichtung ein zweiter Verschiebeantrieb zugeordnet ist und wenn die Hauptheberichteinrichtung mit dem Verschiebeantrieb, mittels einer Steuer- oder Regelanlage, synchron in Stopfmaschinenlängsrichtung verlagerbar sind, womit immer eine optimale vertikale Kraftübertragung gewährleistet ist und unerwünschten Kraftkomponenten in Gleislängsrichtung vermieden werden können.According to the invention, the lifting drives assigned to the main lifting device and the lifting drives assigned to the additional lifting device are displaceable in the tamping machine longitudinal direction via a displacement drive, the lifting drives being mounted on a common slide and displaceable with it in the tamping machine longitudinal direction. The additional lifting device can be shifted along with the main lifting device in the longitudinal direction of the track, so that this shifting device can also be used to select a more favorable point of application for the roller tong (e.g. because a shock at the current point in the junction prevents the roller tong from closing). In this context, it is also advantageous if a displacement sensor is assigned to the displacement drive of the main lifting device and the additional lifting device, if the main lifting device and thus the additional lifting device is assigned a second shifting drive and if the main lifting device is synchronized with the shifting drive by means of a control or regulation system can be displaced in the longitudinal direction of the tamping machine, which always ensures optimal vertical power transmission and undesirable force components in the longitudinal direction of the track can be avoided.

Um eine Krafteinleitung in Gleislängsrichtung auf die Tragarme der Zusatzhebeeinrichtung, durch eine Schrägstellung der Hebeantriebe bei Verschiebung des Haupthebeaggregates in Gleislängsrichtung, zu vermeiden werden die Anlenkpunkte der Hebeantriebe am Hauptrahmen synchron mit verschoben. Zur Bestimmung der Höhendifferenz zwischen der Hauptheberichteinrichtung und dem Tragarm der Zusatzheberichteinrichtung ist ein Distanzsensor vorgesehen, wobei der Tragarm mit dem zugeordneten Hebeantrieb in die Haupthebeebene der Hauptheberichteinrichtung verlagerbar ist. Mit Hilfe des Distanzsensors wird die Höhendifferenz zwischen Haupthebeeinrichtung und Tragarm der Zusatzhebeeinrichtung gemessen. Dadurch kann die Schwenklage des Tragarms gegenüber der Haupthebeeinrichtung kontrolliert und der Tragarm in die gemeinsame Hebeebene gesteuert werden.In order to avoid force transmission in the longitudinal direction of the track on the support arms of the auxiliary lifting device by inclining the lifting drives when the main lifting unit is shifted in the longitudinal direction of the track, the pivot points of the lifting drives on the main frame are shifted synchronously. A distance sensor is provided to determine the height difference between the main lifting device and the support arm of the additional lifting device, the support arm with the associated lifting drive being displaceable into the main lifting plane of the main lifting device. With the aid of the distance sensor, the height difference between the main lifting device and the support arm of the additional lifting device is measured. As a result, the pivot position of the support arm relative to the main lifting device can be controlled and the support arm can be controlled into the common lifting plane.

Führungsrolle und Rollzange greifen vorzugsweise über ein Gelenk mit vertikaler Schwenkachse am teleskopierbaren Tragarm an, wobei zudem ein Drehantrieb vorgesehen sein kann, mit dem Führungsrolle und Rollzange um die Schwenkachse einstellbar sind, um Klemmungen und übermäßigen Verschleiß zu vermeiden.The guide roller and roller tongs preferably engage the telescopic support arm via a joint with a vertical pivot axis, whereby a rotary drive can also be provided with which the guide roller and roller tongs can be adjusted around the pivot axis in order to avoid jamming and excessive wear.
