Description

Die Erfindung betrifft eine Schwingstopfmaschine zum Verdichten eines Schotterbetts eines Gleises gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an oscillating tamping machine for compacting a ballast bed of a track according to the preamble of claim 1.

Aus der WO 2012/139 687 A1 ist eine elektrisch betriebene Schwingstopfmaschine bekannt, die eine Schwingungsentkopplungseinrichtung zwischen Handgriffen zum manuellen Halten der Schwingstopfmaschine und einer rotierenden Unwuchtwelle mit einer daran angeordneten Unwucht aufweist. Durch die Schwingungsentkopplungseinrichtung kann die Übertragung der für die Verdichtung des Schotterbetts bzw. des Schotters erforderlichen Schwingungen auf die Handgriffe wesentlich reduziert werden.From the WO 2012/139687 A1 an electrically operated oscillating tamping machine is known which has a vibration decoupling device between handles for manually holding the oscillating tamping machine and a rotating unbalanced shaft with an unbalanced mass arranged thereon. The transmission of the vibrations required for the compaction of the ballast bed or the ballast to the handles can be significantly reduced by the vibration decoupling device.

Aus der FR 1 385 159 A ist eine Vorrichtung zum Verdichten fließfähiger Materialien durch Vibration einer Schwungmasse bekannt. Die Vorrichtung umfasst Handgriffe, die mittels elastischen Zwischenelementen an einem Antriebsmotor montiert sind.From the FR 1 385 159 A a device for compacting free-flowing materials by vibrating a flywheel mass is known. The device comprises handles which are mounted on a drive motor by means of elastic intermediate elements.

Die CN 2 608 542 Y offenbart eine Vorrichtung zur Instandhaltung von Gleisstrecken, insbesondere einen Elektrohammer.The CN 2 608 542 Y discloses a track maintenance apparatus, in particular an electric hammer.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute und zuverlässige Schwingstopfmaschine zu schaffen, die einen verbesserten Bedienkomfort aufweist.The invention is based on the object of creating a simply constructed and reliable vibrating tamping machine which is more user-friendly.

Diese Aufgabe wird durch eine Schwingstopfmaschine mit den Merkmalen des Anspruchs 1 gelöst. Die Schwingungsentkopplungseinrichtung definiert die Entkopplungsebene, die eine Arbeitsseite von einer Bedienseite trennt. Der Begriff Entkopplungsebene ist funktional derart zu verstehen, dass durch die Schwingungsentkopplungseinrichtung die Bedienseite von der Arbeitsseite schwingungsentkoppelt ist bzw. die Bedienseite gegenüber der Arbeitsseite schwingungsgedämpft ist. Der Begriff Entkopplungsebene ist keinesfalls streng geometrisch als Ebene zu verstehen. Der mindestens eine Handgriff zum Halten der Schwingstopfmaschine ist an der Bedienseite angeordnet. Demgegenüber sind die Vibrationsmechanik und der elektrische Antriebsmotor an der Arbeitsseite angeordnet. Dadurch, dass die Vibrationsmechanik und der elektrische Antriebsmotor zusammen an der Arbeitsseite angeordnet sind, werden sowohl die von dem elektrischen Antriebsmotor als auch die von der Vibrationsmechanik verursachten Kräfte bzw. Schwingungen mittels der Schwingungsentkopplungseinrichtung entkoppelt bzw. gedämpft, so dass diese nur stark gedämpft an dem mindestens einen Handgriff wirken. Dadurch, dass der elektrische Antriebsmotor an der Arbeitsseite angeordnet ist, ist die mechanische Verbindung mit der Vibrationsmechanik einfach und zuverlässig ausgebildet. Es ist nicht erforderlich eine mechanische Antriebswelle durch die Entkopplungsebene zu führen und über die mechanische Antriebswelle übertragene Schwingungen ebenfalls zu entkoppeln bzw. zu dämpfen. Dadurch, dass durch die Entkopplungsebene keine mechanische Verbindung zum Antreiben der Vibrationsmechanik führt, können die Handarmvibrationen bei einer Bedienperson reduziert und der Bedienkomfort erhöht werden. Zudem kann der mindestens eine Handgriff ungestört in eigener Frequenz schwingen, wodurch die Handarmvibrationen reduziert werden. Die Schwingungsentkopplungseinrichtung ist insbesondere derart ausgebildet, dass Handarmvibrationen bei einer Bedienperson einen Grenzwert von 5 m/s2 nicht überschreiten. Durch den Entfall einer mechanischen Verbindung durch die Entkopplungsebene ist die Schwingstopfmaschine einfacher und zuverlässiger aufgebaut, da störungsanfällige Bauteile entfallen.This object is achieved by a vibrating tamping machine having the features of claim 1. Defines the vibration decoupling device the decoupling level that separates a working page from an operating page. The term decoupling level is to be understood functionally in such a way that the vibration decoupling device means that the operating side is vibration-decoupled from the working side or the operating side is vibration-damped relative to the working side. The term decoupling level is by no means to be understood strictly geometrically as a level. The at least one handle for holding the oscillating tamping machine is arranged on the operator side. In contrast, the vibration mechanism and the electric drive motor are arranged on the working side. Due to the fact that the vibration mechanism and the electric drive motor are arranged together on the working side, both the forces or vibrations caused by the electric drive motor and the vibration mechanism are decoupled or damped by means of the vibration decoupling device, so that they are only strongly damped at the work at least one hand movement. Because the electric drive motor is arranged on the working side, the mechanical connection with the vibration mechanism is simple and reliable. It is not necessary to guide a mechanical drive shaft through the decoupling plane and also to decouple or dampen vibrations transmitted via the mechanical drive shaft. Because there is no mechanical connection to drive the vibration mechanism through the decoupling level, the hand arm vibrations of an operator can be reduced and the ease of use increased. In addition, the at least one handle can vibrate undisturbed at its own frequency, which reduces hand arm vibrations. The vibration decoupling device is designed in particular in such a way that hand arm vibrations in the case of an operator do not exceed a limit value of 5 m/s 2 . By eliminating a mechanical connection through the decoupling level the oscillating tamping machine is simpler and more reliable because there are no components that are prone to failure.

Die Vibrationsmechanik ist insbesondere in einem unteren Abschnitt des Stopfpickelrohrs angeordnet. Das Stopfpickelrohr ist vorzugsweise mit der Schwingungsentkopplungseinrichtung verbunden. Der elektrische Antriebsmotor ist insbesondere in dem Stopfpickelrohr zwischen der Vibrationsmechanik und der Schwingungsentkopplungseinrichtung angeordnet. Die Vibrationsmechanik umfasst insbesondere eine Unwucht, die zur Erzeugung einer Vibration bzw. Schwingung ausschließlich radial zu einer Drehachse des Antriebsmotors verlagerbar ist.The electric drive motor and/or the vibration mechanism are preferably arranged in a tube. The tube is also known as a tamping pick tube. The vibration mechanism is arranged in particular in a lower section of the tamping tine tube. The tamping pick tube is preferably connected to the vibration decoupling device. The electric drive motor is arranged in particular in the tamping tine tube between the vibration mechanism and the vibration decoupling device. The vibration mechanism comprises in particular an imbalance which can be displaced exclusively radially to an axis of rotation of the drive motor in order to generate a vibration or oscillation.

Die Schwingstopfmaschine wird im Betrieb von einer Bedienperson manuell gehalten und ist somit handgehalten. Der mindestens eine Handgriff dient insbesondere zum beidhändigen Halten der Schwingstopfmaschine. Die Schwingstopfmaschine wird auch als Schwingstopfer bzw. Handstopfer bezeichnet.During operation, the oscillating tamping machine is held manually by an operator and is therefore hand-held. The at least one handle is used in particular for holding the oscillating tamping machine with both hands. The oscillating tamping machine is also known as an oscillating tamper or manual tamper.

Die Schwingstopfmaschine gewährleistet auf einfache Weise einen hohen Bedienkomfort. Dadurch, dass der Akkumulator an der Bedienseite angeordnet ist, bildet dieser eine Gegenmasse zu der Vibrationsmechanik und dem elektrischen Antriebsmotor, so dass der Akkumulator eine effektive Schwingungsdämpfung bzw. Schwingungsentkopplung an dem mindestens einen Handgriff bewirkt. Der Akkumulator ist zudem vor Schwingungen der Vibrationsmechanik und des elektrischen Antriebsmotors geschützt. Der Akkumulator ist vorzugsweise an einem Traggestell befestigt, an dem wiederum mindestens ein Handgriff und/oder die Schwingungsentkopplungseinrichtung befestigt sind.The oscillating tamping machine ensures a high level of operating comfort in a simple manner. Because the accumulator is arranged on the operating side, it forms a counterweight to the vibration mechanism and the electric drive motor, so that the accumulator brings about effective vibration damping or vibration decoupling on the at least one handle. The accumulator is also protected against vibrations from the vibration mechanism and the electric drive motor. The accumulator is preferably attached to a support frame on which in turn, at least one handle and / or the vibration decoupling device are attached.

Eine Schwingstopfmaschine nach Anspruch 2 gewährleistet einen hohen Bedienkomfort. Der mindestens eine Schwingungsdämpfer ist elastisch ausgebildet, so dass eine Schwingungsentkopplung bzw. Schwingungsdämpfung erzielt wird. Vorzugsweise umfasst der mindestens eine Schwingungsdämpfer ein elastomeres Material, insbesondere ein Gummimaterial. Die Schwingungsentkopplungseinrichtung weist insbesondere mindestens zwei, insbesondere mindestens drei und insbesondere mindestens vier Schwingungsdämpfer auf. Die Schwingungsdämpfer sind vorzugsweise um eine Drehachse des elektrischen Antriebsmotors angeordnet. Durch den mindestens einen Schwingungsdämpfer wird die Entkopplungsebene ausgebildet bzw. definiert.A vibrating tamping machine according to claim 2 ensures a high level of operating comfort. The at least one vibration damper is designed to be elastic, so that vibration decoupling or vibration damping is achieved. The at least one vibration damper preferably comprises an elastomeric material, in particular a rubber material. The vibration decoupling device has in particular at least two, in particular at least three and in particular at least four vibration dampers. The vibration dampers are preferably arranged around an axis of rotation of the electric drive motor. The decoupling plane is formed or defined by the at least one vibration damper.

Eine Schwingstopfmaschine nach Anspruch 3 gewährleistet in einfacher Weise einen hohen Bedienkomfort. Dadurch, dass der Akkumulator auswechselbar an dem Traggestell befestigt ist, kann im Betrieb der Schwingstopfmaschine ein entladener Akkumulator schnell und einfach durch einen geladenen Akkumulator ersetzt und der Betrieb der Schwingstopfmaschine fortgesetzt werden. Der mit dem Akkumulator verbundene Handgriff dient einerseits zum Wechseln des Akkumulators und andererseits zum Halten der Schwingstopfmaschine im Betrieb. Dadurch, dass der Akkumulator und der daran befestigte Handgriff an der Bedienseite angeordnet sind, ist der an dem Akkumulator befestigte Handgriff ebenfalls schwingungsentkoppelt bzw. schwingungsgedämpft.A vibrating tamping machine according to claim 3 ensures a high level of operating comfort in a simple manner. Due to the fact that the accumulator is attached to the support frame in an exchangeable manner, a discharged accumulator can be quickly and easily replaced by a charged accumulator during operation of the oscillating tamping machine and the operation of the oscillating tamping machine can be continued. The handle connected to the accumulator is used on the one hand to change the accumulator and on the other hand to hold the vibrating tamping machine in operation. Due to the fact that the accumulator and the handle attached to it are arranged on the operating side, the handle attached to the accumulator is also vibration-decoupled or vibration-damped.

Eine Schwingstopfmaschine nach Anspruch 4 gewährleistet eine hohe Zuverlässigkeit und einen hohen Bedienkomfort. Dadurch, dass die Steuereinrichtung an der Bedienseite angeordnet ist, ist diese vor ungedämpften Kräften bzw. Schwingungen der Vibrationsmechanik und des elektrischen Antriebsmotors geschützt, wodurch die Zuverlässigkeit der Schwingstopfmaschine hoch ist. Die Steuereinrichtung umfasst insbesondere mindestens ein Bedienelement zum Ansteuern des elektrischen Antriebsmotors, das in einfacher Weise an der schwingungsentkoppelten bzw. schwingungsgedämpften Bedienseite nahe des mindestens einen Handgriffs bzw. an dem mindestens einen Handgriff befestigt ist.A vibrating tamping machine according to claim 4 ensures a high level of reliability and ease of use.

Eine Schwingstopfmaschine nach Anspruch 5 gewährleistet auf einfache Weise einen hohen Bedienkomfort. Dadurch, dass durch die Entkopplungsebene ausschließlich Leitungen verlaufen, also durch die Entkopplungsebene keine mechanische Verbindung zum Antreiben der Vibrationsmechanik verläuft, wird eine optimale Schwingungsentkopplung bzw. Schwingungsdämpfung ermöglicht. Die Leitungen sind insbesondere flexibel ausgebildet. Leitungen sind elektrische Leitungen zur Ansteuerung und Energieversorgung des elektrischen Antriebsmotors und gegebenenfalls einer Kühleinrichtung sowie gegebenenfalls mindestens eine Kühlmittelleitung. Dadurch, dass der Akkumulator an der Bedienseite und der elektrische Antriebsmotor zusammen mit der Vibrationsmechanik an der Arbeitsseite angeordnet sind, ist es ausreichend, dass durch die Entkopplungsebene ausschließlich elektrische Leitungen zur Ansteuerung und zur Energieversorgung und gegebenenfalls mindestens eine Kühlmittelleitung verlaufen. Die Leitungen übertragen im Wesentlichen keine Kräfte bzw. Schwingungen von der Arbeitsseite zu der Bedienseite.A vibrating tamping machine according to claim 5 ensures a high level of operating comfort in a simple manner.

Lines are electrical lines for controlling and supplying energy to the electric drive motor and optionally a cooling device and optionally at least one coolant line. Since the accumulator is on the operating side and the electric drive motor is arranged on the working side together with the vibration mechanism, it is sufficient for only electrical lines for control and for the energy supply and possibly at least one coolant line to run through the decoupling level. The lines essentially do not transmit any forces or vibrations from the working side to the operating side.

Eine Schwingstopfmaschine nach Anspruch 6 gewährleistet eine hohe Zuverlässigkeit. Mittels der Kühleinrichtung ist die im Betrieb der Schwingstopfmaschine von dem elektrischen Antriebsmotor und/oder der Vibrationsmechanik erzeugte Wärme einfach abführbar, so dass der elektrische Antriebsmotor und/oder die Vibrationsmechanik ausreichend gekühlt werden. Die Kühleinrichtung ist an der Bedienseite und/oder an der Arbeitsseite angeordnet, so dass zum Betrieb der Kühleinrichtung durch die Entkopplungsebene ausschließlich mindestens eine elektrische Leitung und/oder mindestens eine Kühlmittelleitung verlaufen. Die Kühleinrichtung ist beispielsweise ein elektrisch betreibbarer Ventilator und nutzt als Kühlmittel Luft. Weiterhin umfasst die Kühleinrichtung beispielsweise eine Pumpe und einen Kühler zum Fördern und Kühlen einer Flüssigkeit als Kühlmittel.A vibrating tamping machine according to claim 6 ensures high reliability. By means of the cooling device, the electric drive motor and/or the vibration mechanism is used during operation of the oscillating tamping machine generated heat easily dissipated, so that the electric drive motor and / or the vibration mechanism are sufficiently cooled.

Eine Schwingstopfmaschine nach Anspruch 7 gewährleistet auf einfache Weise eine hohe Zuverlässigkeit und einen hohen Bedienkomfort. Das Rohr bzw. Stopfpickelrohr, das zwischen der Schwingungsentkopplungseinrichtung und einem freien Ende der Schwingstopfmaschine angeordnet ist, hat eine Länge L. Das Stopfpickelrohr kann einteilig oder mehrteilig ausgebildet sein. Das Stopfpickelrohr weist einen oberen Abschnitt und einen unteren Abschnitt auf. Der obere Abschnitt weist eine Länge LO auf, wobei gilt: LO ≤ 0,7 L, insbesondere LO ≤ 0,5 L, und insbesondere LO ≤ 0,3 L. Durch die Anordnung des elektrischen Antriebsmotors in dem oberen Abschnitt und außerhalb des unteren Abschnitts ist die ungedämpfte Masse der Schwingstopfmaschine im Bereich des unteren Abschnitts hoch. Hierdurch ermöglicht die Schwingstopfmaschine mittels der Vibrationsmechanik einen effizienten Betrieb.

The upper section has a length L 0 , where the following applies: LO ≦0.7 L, in particular LO ≦0.5 L, and in particular LO ≦0.3 L. By arranging the electric drive motor in the upper section and outside the lower section, the undamped mass of the vibrating tamping machine is high in the area of the lower section. As a result, the vibration tamping machine enables efficient operation using the vibration mechanism. In contrast, the electric drive motor is arranged comparatively close to the decoupling plane and to an end of the tamping pick tube connected to the vibration decoupling device, so that maintenance and, if necessary, cooling of the electric drive motor is easily possible.

Die Schwingungsentkopplungseinrichtung 21 bzw. die Schwingungsdämpfer 24 bilden eine Entkopplungsebene E aus, die eine Arbeitsseite 26 von einer Bedienseite 27 entkoppelt. An der Arbeitsseite 26 sind das Stopfpickelrohr 6, der elektrische Antriebsmotor 2, die Antriebswelle 3 und die Vibrationsmechanik 4 angeordnet. Demgegenüber sind an der Bedienseite 27 das Traggestell 12 mit den Handgriffen 13, 14 sowie der Akkumulator 16 mit dem Handgriff 17 und die Steuereinrichtung 18 angeordnet.The vibration decoupling device 21 or the vibration dampers 24 form a decoupling plane E, which decouples a working side 26 from an operating side 27 .
