Description

Schwingstopfmaschine zum Verdichten eines Schotterbetts eines Glei ses  Swinging tamping machine for compacting a ballast bed of a slide
Die Erfindung betrifft eine Schwingstopfmaschine zum Verdichten eines Schotterbetts eines Gleises gemäß dem Oberbegriff des Anspruchs 1. The invention relates to a vibrating tamping machine for compacting a ballast bed of a track according to the preamble of claim 1.
Aus der WO 2012/139 687 Al ist eine elektrisch betriebene Schwing- stopfmaschine bekannt, die eine Schwingungsentkopplungseinrichtung zwischen Handgriffen zum manuellen Halten der Schwingstopfmaschine und einer rotierenden Unwuchtwelle mit einer daran angeordneten Un- wucht aufweist. Durch die Schwingungsentkopplungseinrichtung kann die Übertragung der für die Verdichtung des Schotterbetts bzw. des Schotters erforderlichen Schwingungen auf die Handgriffe wesentlich reduziert wer- den. An electrically operated vibrating tamping machine is known from WO 2012/139 687 A1, which has a vibration decoupling device between handles for manually holding the vibrating tamping machine and a rotating unbalanced shaft with an imbalance arranged thereon. The vibration decoupling device can significantly reduce the transmission of the vibrations required for the compression of the ballast bed or the ballast to the handles.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute und zuverlässige Schwingstopfmaschine zu schaffen, die einen verbesserten Bedienkomfort aufweist. The invention has for its object to provide a simply constructed and reliable vibrating tamping machine that has improved ease of use.
Diese Aufgabe wird durch eine Schwingstopfmaschine mit den Merkmalen des Anspruchs 1 gelöst. Die Schwingungsentkopplungseinrichtung defi- niert 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 Bediensei- te angeordnet. Demgegenüber sind die Vibrationsmechanik und der elektri- sche Antriebsmotor an der Arbeitsseite angeordnet. Dadurch, dass die Vib- rationsmechanik und der elektrische Antriebsmotor zusammen an der Ar- beitsseite angeordnet sind, werden sowohl die von dem elektrischen An- triebsmotor als auch die von der Vibrationsmechanik verursachten Kräfte bzw. Schwingungen mittels der Schwingungsentkopplungseinrichtung ent- koppelt bzw. gedämpft, so dass diese nur stark gedämpft an dem mindes- tens 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 erfor- derlich 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 Ent- kopp lungsebene keine mechanische Verbindung zum Antreiben der Vibra- tionsmechanik führt, können die Handarmvibrationen bei einer Bedienper- son reduziert und der Bedienkomfort erhöht werden. Zudem kann der min- destens eine Handgriff ungestört in eigener Frequenz schwingen, wodurch die Handarmvibrationen reduziert werden. Die Schwingungsentkopplungs- einrichtung 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 Entkopp- lungsebene ist die Schwingstopfmaschine einfacher und zuverlässiger auf- gebaut, da störungsanfällige Bauteile entfallen. This object is achieved by a vibrating tamping machine with the features of claim 1. The vibration decoupling device defines the decoupling level that separates a working side from an operating side. The term decoupling level is to be understood functionally in such a way that the operating side is vibration-decoupled from the working side by the vibration decoupling device 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 vibrating tamping machine is arranged on the operating side. In contrast, the vibration mechanics and the electrical cal drive motor arranged on the working side. Because 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 vibrations mechanics are decoupled or damped by means of the vibration decoupling device, so that they only act strongly damped on at least one handle. Because the electric drive motor is arranged on the working side, the mechanical connection to the vibration mechanism is simple and reliable. It is not necessary to guide a mechanical drive shaft through the decoupling plane and to decouple or damp vibrations transmitted via the mechanical drive shaft. Because no mechanical connection leads to driving the vibration mechanism through the decoupling level, the hand arm vibrations for an operator can be reduced and the operating comfort can be increased. In addition, the at least one handle can vibrate at its own frequency undisturbed, which reduces hand arm vibrations. The vibration decoupling device is in particular designed such that hand arm vibrations for an operator do not exceed a limit value of 5 m / s 2 . Due to the elimination of a mechanical connection through the decoupling level, the vibrating tamping machine has a simpler and more reliable design, since components prone to failure are eliminated.
Der elektrische Antriebsmotor und/oder die Vibrationsmechanik sind vor- zugsweise in einem Rohr angeordnet. Das Rohr wird auch als Stopfpickel- rohr bezeichnet. Die Vibrationsmechanik ist insbesondere in einem unteren Abschnitt des Stopfpickelrohrs angeordnet. Das Stopfpickelrohr ist vor- zugsweise mit der Schwingungsentkopplungseinrichtung verbunden. Der elektrische Antriebsmotor ist insbesondere in dem Stopfpickelrohr zwi- sehen der Vibrationsmechanik und der Schwingungsentkopplungseinrich- tung angeordnet. Die Vibrationsmechanik umfasst insbesondere eine Un- wucht, 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 called a tamping tube. The vibration mechanism is arranged in particular in a lower section of the tamping tube. The tamping tube is preferably connected to the vibration decoupling device. The electric drive motor is in particular in the tamping tube between see the vibration mechanism and the vibration decoupling device arranged. The vibration mechanism includes, in particular, an unbalance that can only be displaced 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 manu- ell gehalten und ist somit handgehalten. Der mindestens eine Handgriff dient insbesondere zum beidhändigen Halten der Schwingstopfmaschine. Die Schwingstopfmaschine wird auch als Schwingstopfer bzw. Handstop- fer bezeichnet. The vibrating tamping machine is held manually by an operator during operation and is therefore hand-held. The at least one handle is used in particular to hold the vibrating tamping machine with both hands. The vibrating tamping machine is also referred to as a vibrating tamper or hand tamper.

Schwingungs- dämpfung erzielt wird. Vorzugsweise umfasst der mindestens eine A vibrating tamping machine according to claim 2 ensures high ease of use. The at least one vibration damper is designed to be elastic, so that vibration decoupling or vibration damping is achieved. The at least one preferably comprises
Schwingungsdämpfer ein elastomeres Material, insbesondere ein Gummi- material. Die Schwingungsentkopplungseinrichtung weist insbesondere mindestens zwei, insbesondere mindestens drei und insbesondere mindes- tens vier Schwingungsdämpfer auf. Die Schwingungsdämpfer sind vor- zugsweise um eine Drehachse des elektrischen Antriebsmotors angeordnet. Durch den mindestens einen Schwingungsdämpfer wird die Entkopplungs- ebene ausgebildet bzw. definiert. Vibration damper an elastomeric material, especially 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 level is formed or defined by the at least one vibration damper.
Eine Schwingstopfmaschine nach Anspruch 3 gewährleistet auf einfache Weise einen hohen Bedienkomfort. Dadurch, dass der Akkumulator an der Bedienseite angeordnet ist, bildet dieser eine Gegenmasse zu der Vibrati- onsmechanik und dem elektrischen Antriebsmotor, so dass der Akkumula- tor eine effektive Schwingungsdämpfung bzw. Schwingungsentkopplung an dem mindestens einen Handgriff bewirkt. Der Akkumulator ist zudem vor Schwingungen der Vibrationsmechanik und des elektrischen An- triebsmotors geschützt. Der Akkumulator ist vorzugsweise an einem Trag- gestell befestigt, an dem wiederum mindestens ein Handgriff und/oder die Schwingungsentkopplungseinrichtung befestigt sind. A vibrating tamping machine according to claim 3 ensures high ease of use 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 effects effective vibration damping or vibration decoupling on the at least one handle. The accumulator is also protected against vibrations of the vibration mechanics 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 4 gewährleistet in einfacher Weise einen hohen Bedienkomfort. Dadurch, dass der Akkumulator aus- wechselbar an dem Traggestell befestigt ist, kann im Betrieb der Schwing- stopfmaschine 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 schwingungsent- koppelt bzw. schwingungsgedämpft. A vibrating tamping machine according to claim 4 ensures a high level of operating convenience in a simple manner. Because the accumulator is exchangeably fastened to the support frame, an discharged accumulator can be quickly and easily replaced by a charged accumulator while the vibrating tamping machine is in operation, and the operation of the vibrating tamping machine can be continued. The handle connected to the accumulator serves on the one hand to change the accumulator and on the other hand to hold the vibrating tamping machine in operation. Because 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 5 gewährleistet eine hohe Zu verlässigkeit und einen hohen Bedienkomfort. Dadurch, dass die Steuerein- richtung an der Bedienseite angeordnet ist, ist diese vor ungedämpften Kräften bzw. Schwingungen der Vibrationsmechanik und des elektrischen Antriebsmotors geschützt, wodurch die Zuverlässigkeit der Schwingstopf- maschine hoch ist. Die Steuereinrichtung umfasst insbesondere mindestens ein Bedienelement zum Ansteuern des elektrischen Antriebsmotors, das in einfacher Weise an der schwingungsentkoppelten bzw. schwingungsge- dämpften Bedienseite nahe des mindestens einen Handgriffs bzw. an dem mindestens einen Handgriff befestigt ist. Eine Schwingstopfmaschine nach Anspruch 6 gewährleistet auf einfache Weise einen hohen Bedienkomfort. Dadurch, dass durch die Entkopp- lungsebene ausschließlich Leitungen verlaufen, also durch die Entkopp- lungsebene keine mechanische Verbindung zum Antreiben der Vibrati- onsmechanik verläuft, wird eine optimale Schwingungsentkopplung bzw. Schwingungsdämpfung ermöglicht. Die Leitungen sind insbesondere flexi- bel ausgebildet. Leitungen sind elektrische Leitungen zur Ansteuerung und Energieversorgung des elektrischen Antriebsmotors und gegebenenfalls einer Kühleinrichtung sowie gegebenenfalls mindestens eine Kühlmittellei- tung. Dadurch, dass der Akkumulator an der Bedienseite und der elektri- sche Antriebsmotor zusammen mit der Vibrationsmechanik an der Arbeits- seite angeordnet sind, ist es ausreichend, dass durch die Entkopplungsebe- ne ausschließlich elektrische Leitungen zur Ansteuerung und zur Energie- versorgung und gegebenenfalls mindestens eine Kühlmittelleitung verlau- fen. Die Leitungen übertragen im Wesentlichen keine Kräfte bzw. Schwin- gungen von der Arbeitsseite zu der Bedienseite. A vibrating tamping machine according to claim 5 ensures a high level of reliability and ease of use. Because the control device is arranged on the operating side, it is protected against undamped forces or vibrations of the vibration mechanism and the electric drive motor, as a result of which the reliability of the vibrating tamping machine is high. The control device comprises in particular at least one control element for controlling the electric drive motor, which is fastened in a simple manner on the vibration-decoupled or vibration-damped operating side near the at least one handle or on the at least one handle. A vibrating tamping machine according to claim 6 ensures high ease of use in a simple manner. Optimal vibration decoupling or vibration damping is made possible by the fact that only lines run through the decoupling level, that is, no mechanical connection for driving the vibration mechanism runs through the decoupling level. The lines are particularly flexible. Lines are electrical lines for controlling and supplying energy to the electric drive motor and possibly a cooling device and optionally at least one coolant line. Due to the fact that the accumulator is arranged on the operating side and the electric drive motor together with the vibration mechanism on the working side, it is sufficient that through the decoupling level only electrical lines for control and energy supply and possibly at least one Coolant line runs. The cables essentially do not transmit any forces or vibrations from the working side to the operating side.
Eine Schwingstopfmaschine nach Anspruch 7 gewährleistet eine hohe Zu- verlässigkeit. Mittels der Kühleinrichtung ist die im Betrieb der Schwing- stopfmaschine von dem elektrischen Antriebsmotor und/oder der Vibrati- onsmechanik erzeugte Wärme einfach abführbar, so dass der elektrische Antriebsmotor und/oder die Vibrationsmechanik ausreichend gekühlt wer- den. Die Kühleinrichtung ist an der Bedienseite und/oder an der Arbeitssei- te angeordnet, so dass zum Betrieb der Kühleinrichtung durch die Entkopp- lungsebene ausschließlich mindestens eine elektrische Leitung und/oder mindestens eine Kühlmittelleitung verlaufen. Die Kühleinrichtung ist bei- spielsweise 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 Kühlmit- tel. A vibrating tamping machine according to claim 7 ensures high reliability. The heat generated by the electric drive motor and / or the vibration mechanism during operation of the vibrating tamping machine can be easily removed by means of the cooling device, so that the electric drive motor and / or the vibration mechanism are sufficiently cooled. The cooling device is arranged on the operating side and / or on the working side, so that only at least one electrical line and / or at least one coolant line run through the decoupling level to operate the cooling device. The cooling device is, for example, an electrically operable fan and uses air as the coolant. The cooling device further comprises, for example, a pump and a cooler for conveying and cooling a liquid as a coolant.
Eine Schwingstopfmaschine nach Anspruch 8 gewährleistet auf einfache Weise eine hohe Zuverlässigkeit und einen hohen Bedienkomfort. Das Rohr bzw. Stopfpickelrohr, das zwischen der Schwingungsentkopplungs- einrichtung 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. Hier- durch ermöglicht die Schwingstopfmaschine mittels der Vibrationsmecha- nik einen effizienten Betrieb. Demgegenüber ist der elektrische An- triebsmotor vergleichsweise nahe an der Entkopplungsebene und einem mit der Schwingungsentkopplungseinrichtung verbundenen Ende des Stopfpi- ckelrohrs angeordnet, so dass die Wartung und gegebenenfalls Kühlung des elektrischen Antriebsmotors einfach möglich ist. A vibrating tamping machine according to claim 8 ensures a high level of reliability and ease of use in a simple manner. The tube or tamping tube, which is arranged between the vibration decoupling device and a free end of the vibration tamping machine, has a length L. The tamping tube can be made in one piece or in several parts. The tamping tube has an upper section and a lower section. The upper section has a length Lo, where: Lo <0.7 L, in particular Lo <0.5 L, and in particular Lo <0.3 L. Due to the arrangement of the electric drive motor in the upper section and outside of the lower Section, the undamped mass of the vibrating tamping machine is high in the area of the lower section. In this way, the vibrating tamping machine enables efficient operation by means of the vibration mechanism. In contrast, the electric drive motor is arranged comparatively close to the decoupling plane and an end of the stuffing tube connected to the vibration decoupling device, so that the maintenance and cooling of the electric drive motor is easily possible.
Eine Schwingstopfmaschine nach Anspruch 9 gewährleistet einen einfa- chen Aufbau und einen hohen Bedienkomfort. Das Rohr bzw. Stopfpickel- rohr, 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 untere Abschnitt weist eine Länge Lu auf, wobei gilt: Lu < 0,3 L, insbesondere Lu < 0,5 L, und insbesondere Lu < 0,7 L. Dadurch, dass der elektrische Antriebsmotor und die Vibrationsmechanik in dem unteren Ab- schnitt angeordnet sind, ist der mechanische Aufbau einfach. Eine zusätzli- che Antriebswelle zwischen der Vibrationsmechanik und dem elektrischen Antriebsmotor ist nicht erforderlich. A vibrating tamping machine according to claim 9 ensures a simple structure and a high level of operating comfort. The tube or tamping tube, which is arranged between the vibration decoupling device and a free end of the vibrating tamping machine, has a length L. The tamping tube can be made in one piece or in several parts. The tamping tube has an upper section and a lower section. The lower section has a length Lu, where: Lu <0.3 L, in particular Lu <0.5 L, and in particular Lu <0.7 L. The fact that the electric drive motor and the vibration mechanism are arranged in the lower section, the mechanical structure is simple. An additional drive shaft between the vibration mechanism and the electric drive motor is not necessary.

Demgegenüber gilt für die Länge Lu: Lu < 0,3 L, insbesondere Lu < 0,5 L, und insbesondere Lu < 0,7 L. The electric drive motor 2, the drive shaft 3 and the vibration mechanism 4 are arranged in a tube or tamping tube 6. The tamping tube 6 has an axial length L and is in an upper Section 7 and a lower section 8 divided. The upper section 7 has an axial length Lo, whereas the lower section 8 has an axial length Lu. The following applies to the length Lo: Lo <0.7 L, in particular Lo <0.5 L, and in particular Lo <0.3 L. In contrast, the following applies to the length Lu: Lu <0.3 L, in particular Lu <0, 5 L, and especially Lu <0.7 L.
Das Stopfpickelrohr 6 umfasst einen rohrförmigen Grundkörper 9, an dem auswechselbar ein Stopfwerkzeug 10 befestigt ist. Das Stopfwerkzeug 10 weist beispielsweise mehrere über den Umfang verteilte und sich radial erstreckende Stopfplatten 11 auf. The tamping pickle tube 6 comprises a tubular base body 9 to which a tamping tool 10 is exchangeably fastened. The tamping tool 10 has, for example, a plurality of tamping plates 11 which are distributed over the circumference and extend radially.
Der elektrische Antriebsmotor 2 ist an einem dem Stopfwerkzeug 10 ab- gewandten Ende des Stopfpickelrohrs 6 in dem oberen Abschnitt 7 und außerhalb des unteren Abschnitts 8 angeordnet. Demgegenüber ist die Vib- rationsmechanik 4 nahe dem Stopfwerkzeug 10 in dem unteren Abschnitt 8 und außerhalb des oberen Abschnitts 7 angeordnet. Die Antriebswelle 3 ist mittels eines Lagers 15 in dem Stopfpickelrohr 6 gelagert. The electric drive motor 2 is arranged on an end of the tamping pickle tube 6 facing away from the tamping tool 10 in the upper section 7 and outside the lower section 8. In contrast, the vibration mechanism 4 is arranged near the tamping tool 10 in the lower section 8 and outside of the upper section 7. The drive shaft 3 is mounted in the tamping tube 6 by means of a bearing 15.
Die Schwingstopfmaschine 1 umfasst weiterhin ein Traggestell 12, an dem ein erster Handgriff 13 und ein zweiter Handgriff 14 seitlich angeordnet sind. An dem Traggestell 12 ist ein Akkumulator 16 auswechselbar befes- tigt. Der Akkumulator 16 ist mit einem dritten Handgriff 17 verbunden.The vibrating tamping machine 1 further comprises a support frame 12 on which a first handle 13 and a second handle 14 are arranged laterally. An accumulator 16 is exchangeably fastened to the support frame 12. The accumulator 16 is connected to a third handle 17.
Der Akkumulator 16 versorgt den elektrischen Antriebsmotor 2 und eine Steuereinrichtung 18 mit elektrischer Energie. Die Steuereinrichtung 18 umfasst eine Steuerung 19, die an dem Traggestell 12 befestigt ist, und eine Bedieneinheit 20, die an den Handgriffen 13, 14 angeordnet ist. Die Bedie- neinheit 20 weist beispielsweise mindestens ein Bedienelement zum An- steuern des elektrischen Antriebsmotors 2 auf. Zur Schwingungsentkopplung der Handgriffe 13, 14, 17 von der Vibrati- onsmechanik 4 und dem elektrischen Antriebsmotor 2 weist die Schwing- stopfmaschine 1 eine Schwingungsentkopplungseinrichtung 21 auf. Die Schwingungsentkopplungseinrichtung 21 umfasst ein bedienerseitiges Be- festigungselement 22, das an dem Traggestell 12 befestigt ist, und arbeits- seitige Befestigungselemente 23, die an dem Stopfpickelrohr 6 befestigt sind. Die Schwingungsentkopplungseinrichtung 21 umfasst weiterhin meh- rere erste Schwingungsdämpfer 24, die das bedienerseitige Befestigungs- element 22 mit den arbeitsseitigen Befestigungselementen 23 verbinden. Beispielhaft weist die Schwingstopfmaschine 1 vier Schwingungsdämpfer 24 auf, die um die Drehachse 5 des elektrischen Antriebsmotors 2 ange- ordnet sind. Weiterhin umfasst die Schwingungsentkopplungseinrichtung 21 mehrere zweite Schwingungsdämpfer 25, die die Handgriffe 13, 14 mit dem bedienerseitigen Befestigungselement 22 und dem Traggestell 12 ver- binden. Die Schwingungsdämpfer 24, 25 sind aus einem elastomeren Mate- rial hergestellt, beispielsweise aus einem Gummimaterial. The accumulator 16 supplies the electric drive motor 2 and a control device 18 with electrical energy. The control device 18 comprises a controller 19, which is fastened to the support frame 12, and an operating unit 20, which is arranged on the handles 13, 14. The control unit 20 has, for example, at least one control element for controlling the electric drive motor 2. For the vibration decoupling of the handles 13, 14, 17 from the vibration mechanism 4 and the electric drive motor 2, the vibrating tamping machine 1 has a vibration decoupling device 21. The vibration decoupling device 21 comprises a fastening element 22 on the operator side, which is fastened to the support frame 12, and work-side fastening elements 23, which are fastened to the tamping tube 6. The vibration decoupling device 21 further comprises a plurality of first vibration dampers 24, which connect the fastening element 22 on the operator side to the fastening elements 23 on the working side. As an example, the vibrating tamping machine 1 has four vibration dampers 24, which are arranged about the axis of rotation 5 of the electric drive motor 2. Furthermore, the vibration decoupling device 21 comprises a plurality of second vibration dampers 25, which connect the handles 13, 14 to the fastening element 22 on the operator side and the support frame 12. The vibration dampers 24, 25 are made from an elastomeric material, for example from a rubber material.
Die Schwingungsentkopplungseinrichtung 21 bzw. die Schwingungsdämp- fer 24 bilden eine Entkopplungsebene E aus, die eine Arbeitsseite 26 von einer Bedienseite 27 entkoppelt. An der Arbeitsseite 26 sind das Stopfpi- ckelrohr 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. The stuffing tube 6, the electric drive motor 2, the drive shaft 3 and the vibration mechanism 4 are arranged on the working side 26. In contrast, the support frame 12 with the handles 13, 14 and the accumulator 16 with the handle 17 and the control device 18 are arranged on the operating side 27.
Durch die Entkopplungsebene E verlaufen ausschließlich elektrische Lei- tungen 28 zur Steuerung und Energieversorgung des elektrischen An- triebsmotors 2 von der Bedienseite 27 zu der Arbeitsseite 26. Die elektri- schen Leitungen 28 sind in Fig. 2 lediglich schematisch veranschaulicht. Die elektrischen Leitungen 28 sind durch einen Gummibalg 29 geschützt. Electrical lines 28 for controlling and supplying energy to the electric drive motor 2 run exclusively from the operating side 27 to the working side 26 through the decoupling level E. The electrical lines 28 are only schematically illustrated in FIG. 2. The electrical lines 28 are protected by a rubber bellows 29.
Die Schwingstopfmaschine 1 dient zum Verdichten eines Schotterbetts S eines Gleises, insbesondere unterhalb von Schwellen des Gleises. Mittels der Steuereinrichtung 18 wird der elektrische Antriebsmotor 2 von einer Bedienperson so angesteuert, dass das Schotterbett S mittels des im Schot- terbett S befindlichen Stopfwerkzeugs 10 in der gewünschten Weise ver- dichtet wird. Hierbei hält die Bedienperson die Schwingstopfmaschine 1 beidhändig, beispielsweise an den Handgriffen 13 und 14. Durch die Schwingungsentkopplungseinrichtung 21 werden durch den elektrischen Antriebsmotor 2 und die Vibrationsmechanik 4 verursachte Kräfte bzw. Schwingungen wirkungsvoll gedämpft, so dass die Arbeitsseite 26 von der Bedienseite 27 schwingungsentkoppelt ist. Der Akkumulator 16 wirkt hier- bei auf der Bedienseite 27 als Gegenmasse und bewirkt eine effektive Schwingungsdämpfung. The vibrating tamping machine 1 is used to compact a ballast bed S of a track, in particular below thresholds of the track. By means of the control device 18, the electric drive motor 2 is actuated by an operator in such a way that the ballast bed S is compressed in the desired manner by means of the tamping tool 10 located in the ballast bed S. Here, the operator holds the vibrating tamping machine 1 with both hands, for example on the handles 13 and 14. The vibration decoupling device 21 effectively dampens forces or vibrations caused by the electric drive motor 2 and the vibration mechanism 4, so that the working side 26 is vibration-decoupled from the operating side 27 , The accumulator 16 acts on the operating side 27 as a counter mass and effects an effective vibration damping.
Ist der Akkumulator 16 entladen, so kann dieser in einfacher Weise mittels des Handgriffs 17 ausgetauscht und durch einen geladenen Akkumulator 16 ersetzt werden. Dadurch, dass die Steuereinrichtung 18 auf der Bedien- seite 27 angeordnet ist, ist diese schwingungsgeschützt. If the accumulator 16 is discharged, it can be exchanged in a simple manner by means of the handle 17 and replaced by a charged accumulator 16. The fact that the control device 18 is arranged on the operating side 27 protects it from vibrations.
Nachfolgend ist anhand von Fig. 3 ein zweites Ausführungsbeispiel der Erfindung beschrieben. Im Unterschied zu dem vorangegangenen Ausfüh- rungsbeispiel ist der elektrische Antriebsmotor 2 in dem unteren Abschnitt 8, also außerhalb des oberen Abschnitts 7 des Stopfpickelrohrs 6 angeord- net. Der elektrische Antriebsmotor 2 ist direkt mit der Vibrationsmechanik 4 verbunden, so dass keine zusätzliche Antriebswelle und ein zugehöriges Lager erforderlich sind. Die Schwingstopfmaschine 1 umfasst weiterhin eine Kühleinrichtung 30 mit einem Kühler 31, einer Pumpe 32 und einer Kühlmittelleitung 33. Der Kühler 31 und die Pumpe 32 sind an dem Trag- gestell 12 auf der Bedienseite 27 angeordnet. Die Kühlmitteleitung 33 führt von dem Kühler 31 und der Pumpe 32 durch die Entkopplungsebene E in das Stopfpickelrohr 6 und zu dem Antriebsmotor 2 und der Vibrationsme- chanik 4. Mittels der Pumpe 32 wird ein Kühlmittel durch die Kühlmittel - leitung 33 gepumpt, so dass durch den Antriebsmotor 2 und die Vibrati- onsmechanik 4 erzeugte Wärme aus dem Stopfpickelrohr 6 abgeführt und zu dem Kühler 31 gefördert wird. Mittels des Kühlers 31 wird die dem Kühlmittel zugeführte Wärme wieder in die Umgebung abgeführt. Hin- sichtlich des weiteren Aufbaus und der weiteren Funktionsweise der Schwingstopfmaschine 1 wird auf das vorangegangene Ausführungsbei- spiel verwiesen. A second exemplary embodiment of the invention is described below with reference to FIG. 3. In contrast to the previous exemplary embodiment, the electric drive motor 2 is arranged in the lower section 8, that is to say outside the upper section 7 of the tamping tube 6. The electric drive motor 2 is connected directly to the vibration mechanism 4, so that no additional drive shaft and an associated bearing are required. The vibrating tamping machine 1 further comprises a cooling device 30 with a cooler 31, a pump 32 and a coolant line 33. The cooler 31 and the pump 32 are arranged on the support frame 12 on the operating side 27. The coolant line 33 leads from the cooler 31 and the pump 32 through the decoupling plane E into the tamping pickle tube 6 and to the drive motor 2 and the vibration mechanism 4. A coolant is pumped through the coolant line 33 by means of the pump 32, so that the heat generated by the drive motor 2 and the vibration mechanism 4 is removed from the tamping tube 6 and conveyed to the cooler 31. The heat supplied to the coolant is dissipated into the surroundings again by means of the cooler 31. With regard to the further construction and the further mode of operation of the vibrating tamping machine 1, reference is made to the previous exemplary embodiment.
