Definitions

  • the invention relates to a movable sleeper pick-up machine, in particular in a track renewal train, with a first device for lifting the sleepers out of the track bed and with a second device for lifting the sleepers on a conveyor belt running above the first device in the direction of advance of the machine.
  • the first device for lifting the sleepers consists of a gripping member which can be pivoted about an axis running transversely to the track and with its grippers extending in the direction of advance of the machine during the advancing movement of the machine reaches under the bedding and lifts something.
  • the second device consists of a vertical conveyor equipped with entrainment members for the sleepers, which takes over the sleepers from the gripper member and lifts them to the rear end of a horizontal conveyor belt running in the longitudinal direction.
  • a track renewal train with a sleeper receiving device is known (CH-A-594105), which on the one hand has a rotating wheel with radially projecting grippers for releasing and lifting the sleepers from the bed and on the other hand a tangential to this wheel, against the direction of advance of the machine has upward inclined conveyor belt with drivers.
  • This conveyor belt takes over the sleepers raised by the grippers of the wheel and merges into an essentially horizontal conveyor belt above the device used to lay the new sleepers.
  • this conveyor belt as well as the conveyor belt for bringing in the new sleepers extends opposite to the direction of advance of the machine, which is often unfavorable for reasons of space.
  • the invention has for its object to provide a sleeper recording machine of the type described in the introduction, which makes it possible to raise both single sleepers and double sleepers at a uniform feed speed of the machine regardless of the frequently changing threshold distance and the condition and material of the sleepers and the track bed on the longitudinal conveyor belt , without the risk of jamming and without the sleepers having the base plates, in particular ribbed plates, on the top of the shelf being turned.
  • a sleeper pick-up machine in which the release of the sleepers from the bedding, the lifting of the sleepers and the displacement of the sleepers onto the conveyor belt are each accomplished by separate, simply constructed and controllable organs, which have a defined and also with varying threshold distance ensure trouble-free operation.

  • the driver element consists of a wheel that can be rotated continuously or intermittently with push fingers that can be pressed in elastically.
  • the driver can be controlled by the operator on the machine by hand in order to take irregularities in the threshold distance into account.
  • the fork-shaped threshold lifter which works like a lever, allows double sleepers to be picked up without any problems, so that the work rhythm does not have to be interrupted.
  • guide plates with appropriately designed lower and rear edges can be provided as leading edges.
  • the arrangement is such that the driver element, which has the shape of a wheel or the approximate shape of a half circular disk, runs with its circumference parallel to the curved top of the ramp and therefore delimits a guideway for the sleepers.

Schwellenaufnahmemaschine dieser Art (US-A-4 236452) besteht die erste Einrichtung zum Herausheben der Schwellen aus einem Greiforgan, das um eine quer zum Gleis verlaufende Achse schwenkbar ist und mit seinen sich in Vorschubrichtung der Maschine erstreckenden Greifern während der Vorschubbewegung der Maschine die in der Bettung liegenden Schwellen untergreift und etwas anhebt. Die zweite Einrichtung besteht aus einem mit Mitnahmeorganen für die Schwellen ausgerüsteten Vertikalförderer, der die Schwellen vom Greiferorgan übernimmt und auf das hintere Ende eines in Längsrichtung verlaufenden, horizontalen Förderbandes anhebt. Die einwandfreie Funktion dieser Maschine bei gleichförmig vorrückendem Eleisumbauzug setzt voraus, dass der Abstand der aufzunehmenden Schwellen stets konstant ist und dass keine Doppelschwellen, das heisst also keine zwei unmittelbar benachbarten Schwellen, vorkommen, weil sonst nämlich die einwandfreie und regelmässige Mitnahme aufeinanderfolgender Schwellen durch die Mitnahmeorgane des Vertikalförderers nicht gewährleistet ist. Auch ist eine Führung der Schwellen, insbesondere ihre seitliche Ausrichtung, bei der Aufnahmeoperation keineswegs sichergestellt.Sleeper receiving machine of this type (US-A-4 236452), the first device for lifting the sleepers consists of a gripping member which can be pivoted about an axis running transversely to the track and with its grippers extending in the direction of advance of the machine during the advancing movement of the machine reaches under the bedding and lifts something. The second device consists of a vertical conveyor equipped with entrainment members for the sleepers, which takes over the sleepers from the gripper member and lifts them to the rear end of a horizontal conveyor belt running in the longitudinal direction. The perfect functioning of this machine with a uniformly advancing electric train requires that the distance between the sleepers to be picked up is always constant and that there are no double sleepers, i.e. no two immediately adjacent sleepers, because otherwise the perfect and regular transport of successive sleepers by the transport units of the vertical conveyor is not guaranteed. Guidance of the sleepers, in particular their lateral alignment, is by no means ensured during the admission operation.

Es ist auch bereits bekannt, zur Aufnahme alter Schwellen ein um eine horizontale Achse drehendes, mit Einrichtungen zum Mitnehmen der Schwellen ausgerüstetes Rad vorzusehen, welches die Schwellen sowohl aus der Bettung löst als auch während etwa einer halben Umdrehung mitnimmt und dann einem horizontalen Förderband übergibt (CH-A-600 047). Hierbei gelangen die Schwellen um 180° um ihre horizontale Längsachse gedreht auf dasIt is also already known to provide a wheel that rotates about a horizontal axis and is equipped with devices for taking the sleepers, which both releases the sleepers from the bed and takes them along for about half a turn and then transfers them to a horizontal conveyor belt ( CH-A-600 047). Here, the sleepers are turned by 180 ° about their horizontal longitudinal axis

Förderband.Conveyor belt.

Des weiteren ist ein Gleisumbauzug mit einer Schwellenaufnahmevorrichtung bekannt (CH-A-594105), die einerseits ein drehendes Rad mit radial vorstehenden Greifern zum Lösen und Ausheben der Schwellen aus der Bettung und andererseits ein tangential zu diesem Rade angeordnetes, entgegen der Vorschubrichtung der Maschine stark aufwärts geneigtes Förderband mit Mitnehmern aufweist. Dieses Förderband übernimmt die von den Greifern des Rades angehobenen Schwellen und geht oberhalb der zur Verlegung der neuen Schwellen dienenden Vorrichtung in ein im wesentlichen horizontal verlaufendes Förderband über. Dieses Förderband wie auch das Förderband zum Heranführen der neuen Schwellen erstreckt sich jedoch entgegengesetzt zur Vorschubrichtung der Maschine, was aus Raumgründen häufig ungunstig ist.Furthermore, a track renewal train with a sleeper receiving device is known (CH-A-594105), which on the one hand has a rotating wheel with radially projecting grippers for releasing and lifting the sleepers from the bed and on the other hand a tangential to this wheel, against the direction of advance of the machine has upward inclined conveyor belt with drivers. This conveyor belt takes over the sleepers raised by the grippers of the wheel and merges into an essentially horizontal conveyor belt above the device used to lay the new sleepers. However, this conveyor belt as well as the conveyor belt for bringing in the new sleepers extends opposite to the direction of advance of the machine, which is often unfavorable for reasons of space.

Der Erfindung liegt die Aufgabe zugrunde, eine Schwellenaufnahmemaschine der eingangs beschriebenen Art zu schaffen, die es erlaubt, bei gleichförmiger Vorschubgeschwindigkeit der Maschine sowohl Einzelschwellen als auch Doppelschwellan Unabhängig vom häufig veränderlichen Schwellanabstand und vom Zustand und Material der Schwellen und der Gleisbettung störungsfrei auf das Längsförderband anzuheben, ohne dass die Gefahr eines Verklammens besteht und ohne dass die in der Regal auf ihrer Oberseite Unterlagsplatten, insbesondere Rippenplatten, aufweisenden Schwellen dabei gewendet werden.The invention has for its object to provide a sleeper recording machine of the type described in the introduction, which makes it possible to raise both single sleepers and double sleepers at a uniform feed speed of the machine regardless of the frequently changing threshold distance and the condition and material of the sleepers and the track bed on the longitudinal conveyor belt , without the risk of jamming and without the sleepers having the base plates, in particular ribbed plates, on the top of the shelf being turned.

Diese Aufgabe wird erfindungsgemäss durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.

Auf diese Weise wird eine Schwellenaufnahmemaschine geschaffen, bei welcher das Lösen der Schwellen aus der Bettung, die Anhebung der Schwellen und die Verschiebung der Schwellen auf das Förderband jeweils durch getrennte, einfach aufgebaute und steuerbare Organe bewerkstelligt wird, die einen definierten und auch bei variierendem Schwellenabstand störungsfreien Betrieb gewährleisten.In this way, a sleeper pick-up machine is created in which the release of the sleepers from the bedding, the lifting of the sleepers and the displacement of the sleepers onto the conveyor belt are each accomplished by separate, simply constructed and controllable organs, which have a defined and also with varying threshold distance ensure trouble-free operation.

Zum Herausheben der Schwellen aus der Gleisbettung und zu ihrer Verachiebung auf der aufwärts geneigten Rampe dient vorzugsweise ein Mitnehmerorgan, das mittels einer Antriebseinrichtung um eine horizontale Achse hin- und herschwenkbar ist und einziehbare, durch Antriebsorgane steuerbare Schubfinger hat; dieses Mitnehmerorgan hat zweckmässigerweise die ungefähre Form einer halben Kreisscheibe, kann jedoch gegebenenfalls auch als hin- und herschwenkbarer Hebel ausgebildet sein. Gemäss einer anderen Ausführungsform besteht das Mitnehmerorgan aus einem stetig oder auch intermittierend drehbaren Rade mit elastisch eindrückbaren Schubfingern.For lifting the sleepers out of the track bed and for moving them on the upward inclined ramp, a driver element is preferably used, which can be pivoted back and forth by means of a drive device and has retractable thrust fingers which can be controlled by drive elements; this driving element expediently has the approximate shape of a half circular disk, but can optionally also be designed as a lever which can be pivoted back and forth. According to another embodiment, the driver element consists of a wheel that can be rotated continuously or intermittently with push fingers that can be pressed in elastically.

Das Mitnehmerorgan kann von der auf der Maschine befindlichen Bedienungsperson jeweils von Hand gesteuert werden, um Unregelmässigkeiten im Schwellenabstand zu berücksichtigen. Der gabelförmige Schwellenheber, der wie ein Hebel arbeitet, erlaubt es im Unterschied zu einem Vertikalförderer, ohne weiteres auch Doppelschwellen aufzunehmen, so dass der Arbeitsrhythmus nicht unterbrochen zu werden braucht.The driver can be controlled by the operator on the machine by hand in order to take irregularities in the threshold distance into account. In contrast to a vertical conveyor, the fork-shaped threshold lifter, which works like a lever, allows double sleepers to be picked up without any problems, so that the work rhythm does not have to be interrupted.

Zur einwandfreien Führung der Schwellen während ihrer Verschiebung auf der Rampe und während des Anhebens können Führungsplatten mit entsprechend ausgebildeten unteren und hinteren Kanten als Führungskanten vorgesehen sein. In einer bevorzugten Ausführungsform ist die Anordnung so getroffen, dass das Mitnehmerorgan, welches die Form eines Rades oder die ungefähre Form einer halben Kreisscheibe hat, mit seinem Umfang parallel zur kreisbogenförmig gekrümmten Oberseite der Rampe verläuft und daher mit dieser eine Führungsbahn für die Schwellen begrenzt. Diese Führungsbahn wird schräg nach oben einerseits durch Führungsschienen und andererseits durch Führungshebel begrenzt. Sobald eine Schwelle durch einen Schubfinger hinreichend weit hochgeschoben worden ist und auf den Führungshebeln anliegt, werden diese zusammen mit der Schwelle abwärts verschwenkt, so dass die Schwelle in der für den Weitertransport geeigneten Orientierung vom Schwellenheber übernommen werden kann. Die die Achse des Mitnehmerorgans tragenden Maschinenteile sind vorzugsweise in vertikaler Richtung beweglich am Maschinenrahmen aufgehängt und durch ein Druckorgan in Abwärtsrichtung mit vorgebbarer Kraft beaufschlagbar. Zweckmässige Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Patentansprüchen.For proper guidance of the sleepers during their displacement on the ramp and during lifting, guide plates with appropriately designed lower and rear edges can be provided as leading edges. In a preferred embodiment, the arrangement is such that the driver element, which has the shape of a wheel or the approximate shape of a half circular disk, runs with its circumference parallel to the curved top of the ramp and therefore delimits a guideway for the sleepers. This guideway is limited diagonally upwards on the one hand by guide rails and on the other hand by guide levers. As soon as a threshold has been pushed up sufficiently by a thrust finger and rests on the guide levers, these are pivoted downwards together with the threshold so that the threshold can be taken over by the threshold lifter in the orientation suitable for further transport. The machine parts supporting the axis of the entrainment member are preferably suspended on the machine frame so as to be movable in the vertical direction and can be acted upon by a preselectable force in the downward direction by a pressure member. Appropriate embodiments of the invention result from the dependent claims.

Nach Figur 1 weist der in Richtung des Pfeils vorrückende Gleisumbauzug am vorderen Ende einen auf dem alten Gleis 1 rollenden Transportwagen 2 für die zu verlegenden neuen Schwellen 3 und die ausgebauten alten Schwellen 4 auf. Vor dem Einsatz des Gleisumbauzuges wurden bereits die Befestigungen der Schienen des alten Gleises 1 gelöst. Hinter dem Transportwagen 2 befindet sich ein Arbeitswagen 5 mit Ausrüstungen zum Entfernen der alten Schienen, die angehoben und zu beiden Seiten des Gleiskörpers abgesetzt werden, mit einem in Längsrichtung verlaufenden Förderband 6 für die alten Schwellen 4, dessen Anfangsabschnitt 6a geneigt ist, und einem darüber installierten, in Längsrichtung verlaufenden Förderband 7 für die neuen Schwellen 3. Da sich der Transportwagen 2 für die Schwellen am vorderen Zugende befindet, was aus Raumgründen günstig ist, erstrecken sich beide Förderbänder 6 und 7 längs der vorderen Zughälfte. Ein Portalkran 8 für den Schwellentransport ist auf Laufschienen, die durchgehend auf dem Arbeitswagen 5 und dem Transportwagen 2 verlegt sind, längs dieser beiden Wagen verfahrbar. Der Arbeitswagen 5 rollt mit seinem vorderen Fahrgestell 9 auf dem alten Gleis 1, während er sich mit seinem hinteren Fahrgestell 10 auf einem Schlitten 11 abstützt, der auf den noch in der Bettung befindlichen alten Schwellen 4 gleiten kann.According to FIG. 1, the track renewal train advancing in the direction of the arrow has a transport wagon 2 rolling on the old track 1 for the new sleepers 3 to be laid and the old sleepers 4 removed. Before using the track renewal train, the fastenings of the rails of the old track 1 were already loosened. Behind the transport carriage 2 there is a work carriage 5 with equipment for removing the old rails, which are raised and set down on both sides of the track body, with a longitudinal conveyor belt 6 for the old sleepers 4, the starting section 6a of which is inclined, and one above installed, longitudinally running conveyor belt 7 for the new sleepers 3. Since the transport carriage 2 for the sleepers is at the front end of the train, which is advantageous for space reasons, both conveyor belts 6 and 7 extend along the front half of the train. A gantry crane 8 for the sleeper transport can be moved along these two carriages on running rails which are continuously laid on the work carriage 5 and the transport carriage 2. The work carriage 5 rolls with its front chassis 9 on the old track 1, while it is supported with its rear chassis 10 on a carriage 11 which can slide on the old sleepers 4 still in bed.

Zwischen dem rückwärtigen Ende des Arbeitswagens 5 und dem am hinteren Ende des Gleisumbauzuges auf dem neuen Gleis 12 rollenden Triebwagen 13 ist ein Traggestell 14 montiert, an welchem die erfindungsgemässe, später noch im einzelnen beschriebene Schwellenaufnahmemaschine 15 mit dem geneigten Anfangsabschnitt 6a des Förderbandes 6 für die alten Schwellen 4 ein Schotterpflug 16 zur Aufbereitung der Schotterbettung, eine Vorrichtung 17 zum Absetzen der neuen Schwellen 3 mit dem geneigten Endabschnitt des Förderbandes 7 für diese neuen Schwellen und eine Vorrichtung 18 zur Verlegung der das neue Gleis 3 bildenden neuen Schienen installiert sind; diese neuen Schienen werden vor dem Einsatz des Gleisumbauzuges auf beiden Seiten des Gleises abgelegt.Between the rear end of the work carriage 5 and the railcar 13 rolling at the rear end of the track conversion train on the new track 12, a support frame 14 is mounted, on which the sleeper receiving machine 15 according to the invention, described later in detail, with the inclined initial section 6a of the conveyor belt 6 for the old sleepers 4, a ballast plow 16 for preparing the ballast bed, a device 17 for depositing the new sleepers 3 with the inclined end section of the conveyor belt 7 for these new sleepers and a device 18 for laying the new rails forming the new track 3 are installed; These new rails are placed on both sides of the track before the track renewal train is used.

Die Figuren 2 und 3 zeigen schematisch in Seitenansicht und in Draufsicht die Schwellenaufnahmemaschine 15, wobei nur die zum Verständnis der Erfindung wesentlichen Teile dargestellt sind. Alle diese Teile sind an einem Rahmen 20 montiert, dessen vordere Seite 20a umeine horizontale Achse 21 schwenkbar an einem Verbindungsstück 22 angelenkt ist, welches seinerseits gelenkig mit dem hinteren Ende des Fahrgestellrahmens des Arbeitswagens 5 verbunden ist. An der vorderen Seite 20a des Rahmens 20 sind, symmetrisch zu seiner mittleren Längsachse, zwei vertikale Träger 23 befestigt, an denen mit Hilfe je zweier angelenkter Arme 24 und 25 je eine Führungsplatte 26 in der Höhe verschiebbar montiert ist. Die Arme 24 und 25 sind am unteren bzw. oberen Ende jedes Trägers 23 um die Achsen 27 bzw. 28 schwenkbar, während die Führungsplatte 26 an den anderen Enden der Arme 24 und 25 um die Achsen 29 bzw. 30 schwenkbar aufgehängt ist. Das Ganze bildet also eine Parallelogrammaufhängung für die vertikal beweglichen Führungsplatten 26.Figures 2 and 3 show schematically in side view and in plan view the threshold receiving machine 15, only the parts essential for understanding the invention are shown. All these parts are mounted on a frame 20, the front side 20a of which is pivoted about a horizontal axis 21 on a connecting piece 22, which in turn is articulated to the rear end of the chassis frame of the work car 5. On the front side 20a of the frame 20, two vertical supports 23 are fastened symmetrically to its central longitudinal axis, on each of which a guide plate 26 is slidably mounted in height by means of two articulated arms 24 and 25. Arms 24 and 25 are pivotable at the lower and upper ends of each bracket 23 about axes 27 and 28, respectively, while guide plate 26 is pivotally suspended at the other ends of arms 24 and 25 about axes 29 and 30, respectively. The whole thing thus forms a parallelogram suspension for the vertically movable guide plates 26.

In der Draufsicht nach Figur 3, in der die oberen Arme 25 der erwähnten Parallelogrammaufhängung dargestellt sind, erkennt man, dass die beschriebene Installation und die noch zu beschreibenden Teile der Schwellenaufnahmemaschine beiderseits der zentralen Längsachse im wesentlichen symmetrisch angeordnet und aufgebaut sind, wobei die einander entsprechenden Teile die gleichen Bezugszeichen tragen.In the plan view according to FIG. 3, in which the upper arms 25 of the parallelogram suspension mentioned are shown, it can be seen that the installation described and the parts of the threshold recording machine to be described are arranged and constructed essentially symmetrically on both sides of the central longitudinal axis, the corresponding ones Parts have the same reference numbers.

An der oberen Achse 30 der Parallelogrammaufhängung ist schwenkbar ein Mitnehmerorgan 31 mit einem steuerbaren, einziehbaren Schubfinger 32 aufgehängt, welcher bei Drehung des Mitnehmerorgans 31 entgegengesetzt zum Uhrzeigersinne in der Darstellung nach Figur 2 eine noch in der Schotterbettung befindliche alte Schwelle 4 aus der Bettung löst und entgegengesetzt zur Bewegungsrichtung des Gleisumbauzuges nach hinten verschiebt. Dabei gleitet die alte Schwelle 4 auf einer geneigten gabelförmigen Rampe 33, die durch zwei vertikal orientierte Platten gebildet wird, welche an einer hinteren Traverse 20b des Rahmens 20 sitzen. Die Arbeitsstellung der Rampe 33 kann je nach den Arbeitsbedingungen in einer gewünschten Höhe fest eingestellt werden. Der Abstand zwischen der eine Führungskante für die alten Schwellen 4 bildenden Unterkante 26a der Führungsplatten 26 und der Rampe 33 entspricht, wie in Figur 2 veranschaulicht, der Höhe der alten Schwellen 4, welche auf diese Weise während ihrer Verschiebung durch das Mitnehmerorgan 31 in definierter Weise geführt werden.On the upper axis 30 of the parallelogram suspension, a driver element 31 is pivotally suspended with a controllable, retractable thrust finger 32 which, when the driver element 31 rotates counterclockwise in the illustration according to FIG. 2, releases an old threshold 4 which is still in the ballast bedding and moves backwards to the direction of movement of the track renewal train. The old sleeper 4 slides on an inclined fork-shaped ramp 33 which is formed by two vertically oriented plates which are seated on a rear crossbeam 20b of the frame 20. The working position of the ramp 33 can be set at a desired height depending on the working conditions. The distance between the lower edge 26a of the guide plates 26 forming the leading edge for the old sleepers 4 and the ramp 33 corresponds, as illustrated in FIG. 2, to the height of the old sleepers 4, which in this way during their displacement by the driving element 31 in a defined manner be performed.

Zum Hin- und Herschwenken des Mitnehmerorgans 31 um die Achse 30 dient ein von einem Motor 34 angetriebener Kurbeltrieb. Dazu gehört das mittels eines Treibriemens 35 vom Motor 34 in Drehung versetzte Rad 36, welches auf einer in den beiden Führungsplatten 26 drehbar gelagerten Querwelle 37 sitzt und einen Zapfen 38 aufweist, der in einer Längsnut 39 des Mitnehmerorgans 31 verschiebbar ist..Auf der anderen Seite der Ouerwelle 37 sitzt ein entsprechendes Rad 36 zum Antrieb des anderen Mitnehmerorgans. Zur Steuerung des einziehbaren Schubfingers 32 dient ein in Längsrichtung am Mitnehmerorgan 31 installierter hydraulischer Zylinder 40, der einerseits an einem festen Vorsprung 41 des Mitnehmerorgan 31 und andererseits an einem am Vorschubfinger 32 befestigten und mit diesem längsbeweglichen Schieber 42 angelenkt ist.A crank mechanism driven by a motor 34 serves to pivot the driving element 31 back and forth about the axis 30. This includes the wheel 36 set in rotation by the motor 34 by means of a drive belt 35, which sits on a transverse shaft 37 which is rotatably mounted in the two guide plates 26 and has a pin 38 which is displaceable in a longitudinal groove 39 of the driving element 31 On the side of the shaft 37 there is a corresponding wheel 36 for driving the other driving element. A hydraulic cylinder 40 installed in the longitudinal direction on the driving element 31 is used to control the retractable pushing finger 32, which is articulated on the one hand on a fixed projection 41 of the driving element 31 and on the other hand on a slider 42 which is fastened to the advancing finger 32 and is longitudinally movable therewith.

Im hinteren Bereich der die Rampe 33 bildenden vertikal orientierten Platten ist drehbar eine Welle 45 gelagert, an welcher zwei schwenkbare, als gabelförmiger Schwellenheber 46 fungierende Hebel befestigt sind. Dieser Schwellenheber, der sich also von seiner Drehwelle 45 aus in Vorschubrichtung der Maschine erstreckt, hat in seiner unteren Stellung, welche in den Figuren 4 und 5 dargestellt ist, die gleiche Neigung wie die Rampe 33 und befindet sich in Höhe dieser Rampe 33 oder etwas unterhalb der Rampenebene. In dieser Stellung liegt der Schwellenheber 46 unterhalb derjenigen Zwischenstellung 4 (Figur 4), die eine alte Schwelle 4 nach ihrer Verschiebung durch das Mitnehmerorgan 31 auf der Rampe 33 einnimmt. Mittels eines einerseits am Rahmen 20 und andererseits am Schwellenheber46 angelenkten hydraulischen Zylinders 47 ist der Schwellenheber 46 um die Welle 45 in die in Figur 5 dargestellte obere Stellung verschwenkbar, in welcher er mit dem geneigten Abschnitt 6a des in Längsrichtung verlaufenden Förderbandes 6 fluchtet.In the rear area of the vertically oriented plates forming the ramp 33, a shaft 45 is rotatably mounted, on which two pivotable levers, which act as fork-shaped threshold lifters 46, are fastened. This threshold lifter, which therefore extends from its rotary shaft 45 in the direction of advance of the machine, has the same inclination as the ramp 33 in its lower position, which is shown in FIGS. 4 and 5, and is at the level of this ramp 33 or somewhat below the ramp level. In this position, the threshold lifter 46 lies below the intermediate position 4 (FIG. 4) which an old threshold 4 assumes on the ramp 33 after being displaced by the driver element 31. By means of a hydraulic cylinder 47 articulated on the frame 20 on the one hand and on the other hand on the sleeper lifter 46, the sleeper lifter 46 can be pivoted about the shaft 45 into the upper position shown in FIG. 5, in which it is aligned with the inclined section 6a of the conveyor belt 6 running in the longitudinal direction.

Die Neigung der Rampe 33, die im betrachteten Beispiel etwa 30° beträgt, und der Schwenkwinkel des Schwellenhebers 46, welcher im betrachteten Beispiel etwa 50° beträgt, sind so zu wählen, dass die Schwellen 4 bei ihren Bewegungen nicht stärker als etwa 45° gegen die Horizontale gekippt werden. Im mittleren Bereich jeder der die Rampe 33 bildenden Platten ist mittels eines Zapfens 48 ein als Schwellenstösser 49 fungierender Hebel angelenkt, der mit Hilfe je eines hydraulischen Zylinders 50, welcher einerseits am Rahmen 20 oder an der Rampe 33 und andererseits am Schwellenstösser 49 angelenkt ist, zwischen der vorderen, in Figur 2 und 5 gezeigten und der hinteren, in Figur 4 gezeigten Stellung zwecks Verschiebung einer angehobenen Schwelle 4 auf das Förderband 6a verschwenkbar ist.The inclination of the ramp 33, which is approximately 30 ° in the example under consideration, and the pivoting angle of the threshold lifter 46, which is approximately 50 ° in the example considered, are to be selected such that the thresholds 4 do not move more than approximately 45 ° in their movements the horizontal can be tilted. In the central area of each of the plates forming the ramp 33, a lever 48, which acts as a threshold push rod 49, is articulated by means of a pin 48, which lever is actuated by means of a hydraulic cylinder 50, which is articulated on the one hand on the frame 20 or on the ramp 33 and on the other hand on the threshold push rod 49, between the front position shown in FIGS. 2 and 5 and the rear position shown in FIG. 4 for the purpose of moving a raised threshold 4 onto the conveyor belt 6a.

Um die Führungsplatten 26 mitsamt dem Mitnehmerorgan 31 stets mit einer vorgebbaren Kraft abwärts zu drücken, ist ein Druckorgan 44 in Form eines hydraulischen Zylinders vorgesehen, der nach Figur 2 einerseits an einem Teil des Rahmens 20 und andererseits an dem unteren Arm 24 der erwähnten Parallelaufhängung angelenkt ist und diesen unteren Arm 24 mit einer vorgebbaren Kraft abwärts drückt. Auf diese Weise wird erreicht, dass das Mitnehmerorgan 31 mit seinem Vorschubfinger 32 stets hinreichend tief hinter die auszuhebende Schwelle 4 greift und dass ferner die Führungsplatten 26 mit ihrer unteren Führungskante 26a an den auf der Rampe 33 verschobenen Schwellen anliegen und insbesondere in die Nuten oder Hohlprofile der noch auf den alten Schwellen 4 befestigten Unterlagsplatten 43, insbesondere Rippenplatten eingreifen können, wodurch die seitliche Führung der Schwellen 4 auf der Rampe 33 noch verbessert wird. Wohlgemerkt ist ein derartiges Andruckorgan 44 nicht immer erforderlich, so dass darauf gegebenenfalls auch verzichtet werden kann. Ausserdem ist es möglich, dieses Andruckorgan nur auf das Mitnehmerorgan 31 wirken zu lassen, damit dieses mit vorgebbarer Kraft abwärtsgedrückt wird, während die Führungsplatten 26 relativ zum Rahmen 20 feststehen, vorzugsweise jedoch in ihrer Höhe gemäss den jeweiligen Arbeitsbedingungen einstellbar sind.In order to always press the guide plates 26 together with the driving element 31 downwards with a predeterminable force, a pressure element 44 in the form of a hydraulic cylinder is provided which, according to FIG. 2, is articulated on the one hand on part of the frame 20 and on the other hand on the lower arm 24 of the parallel suspension mentioned is and pushes this lower arm 24 down with a predetermined force. In this way it is achieved that the driving element 31 always reaches sufficiently deep behind the sleeper 4 to be lifted with its feed finger 32 and that the guide plates 26 also rest with their lower guide edge 26a on the sleeper displaced on the ramp 33 and in particular in the grooves or hollow profiles the can still engage on the old sleepers 4 attached support plates 43, in particular ribbed plates, whereby the lateral guidance of the sleepers 4 on the ramp 33 is further improved. It should be noted that such a pressure element 44 is not always necessary, so that it can also be dispensed with if necessary. In addition, it is possible to let this pressure element act only on the driving element 31, so that it is pressed down with a predeterminable force, while the guide plates 26 are fixed relative to the frame 20, but preferably their height can be adjusted according to the respective working conditions.

Nachstehend wird anhand der Figuren 2,4 und 5, welche drei verschiedene Phasen der Arbeitsoperation zeigen, die Funktion der beschriebenen Schwellenaufnahmemaschine näher erläutert. In der Darstellung nach Figur 2 nimmt das Mitnehmerorgan 31 mit seinem Schubfinger 32 seine Anfangsstellung ein, das heisst seine in Bewegungsrichtung der Maschine verschwenkte Stellung ein und ist gerade im Begriff, eine alte Schwelle 4 aus der Bettung heraus und auf die Rampe 33 zu schieben. Der Schwellenheber 46 nimmt seine untere Stellung zur Aufnahme der Schwelle ein. Der Schwellenstösser 49, der in der vorangehenden angehobenen Stellung des Schwellenhebers 46 die darauf befindliche, vorhergehend aufgenommene Schwelle auf das Förderband 6a geschoben hat, nimmt noch die nach vorn verschwenkte Lage ein, ist jedoch im Begriff, in die hintere Lage zu verschwenken.The function of the threshold recording machine described is explained in more detail below with reference to FIGS. 2, 4 and 5, which show three different phases of the work operation. In the illustration according to FIG. 2, the driving element 31 takes up its initial position with its thrust finger 32, that is to say its position pivoted in the direction of movement of the machine, and is just about to push an old threshold 4 out of the bedding and onto the ramp 33. The threshold lifter 46 assumes its lower position for receiving the threshold. The threshold pusher 49, which, in the preceding raised position of the threshold lifter 46, has pushed the previously received threshold located thereon onto the conveyor belt 6a, is still in the position pivoted forward, but is about to pivot into the rear position.

In der Darstellung nach Figur4 hat des Mitnehmerorgan 31 die Schwelle 4 in ihre Zwischenstellung 4' auf der Rampe 33 verschoben und nimmt gerade seine extreme Schwenkstellung ein. Der Schwellenheber 46 befindet sich noch in seiner unteren Lage, in welcher er die Schwelle 4 untergreift. Der Schwellenstösser49 ist in der Zwischenzeit in seine hintere Lage verschwenkt worden. Anschliessend wird der Schwellenheber46 mit der Schwelle 4 in seine obere Lage verschwenkt, während das Mitnehmerorgan 31 in seine Ausgangslage zurückgeschwenkt wird, wobei gleichzeitig der Schubfinger 32 mittels des hydraulischen Zylinders 40 eingezogen wird, damit er die folgende aufzunehmende Schwelle passieren kann.In the illustration according to FIG. 4, the driver element 31 has shifted the threshold 4 into its intermediate position 4 'on the ramp 33 and is currently in its extreme pivot position. The threshold lifter 46 is still in its lower position, in which it engages under the threshold 4. The threshold pusher49 has meanwhile been pivoted into its rear position. The threshold lifter 46 is then pivoted into its upper position with the threshold 4, while the driver element 31 is pivoted back into its starting position, the thrust finger 32 being drawn in at the same time by means of the hydraulic cylinder 40, so that it can pass the following threshold to be picked up.

In der Darstellung nach Figur 5 befindet sich der Schwellenheber 46 in seiner oberen, mit dem hinteren Abschnitt 6a des Förderbandes 6 ausgerichteten Lage, und der Schwellenstösser 49 ist bereits in seine vordere Stellung verschwenkt worden, wodurch die angehobene Schwelle 4 vom Schwellenheber 46 auf das hintere Ende des Förderbandes 6a geschoben wurde. Dieses Förderband ist vorzugsweise mit Querrippen 51 versehen, damit die Schwellen 4 besser mitgenommen werden. Das Mitnehmerorgan 31 befindet sich in seiner Ausgangslage hinter der folgenden, aufzunehmenden Schwelle 4, und sein Schubfinger 32 ist in dieser Stellung bereits wieder durch den hydraulischen Zylinder 40 nach unten ausgeschoben worden. Anschliessend wird der Schwellenheber 46 wieder in seine untere Stellung verschwenkt, woraufhin die folgende Schwelle 4 auf die Rampe 33 in die Zwischenstellung 4' geschoben werden kann, usw.5, the threshold lifter 46 is in its upper position aligned with the rear section 6a of the conveyor belt 6, and the threshold lifter 49 has already been pivoted into its front position, as a result of which the raised threshold 4 is moved from the threshold lifter 46 to the rear End of the conveyor belt 6a was pushed. This conveyor belt is preferably provided with transverse ribs 51, so that the sleepers 4 are better carried along. The driving element 31 is in its starting position behind the following threshold 4 to be picked up, and its thrust finger 32 has already been pushed out again by the hydraulic cylinder 40 in this position. The threshold lifter 46 is then pivoted back into its lower position, whereupon the following threshold 4 can be pushed onto the ramp 33 into the intermediate position 4 ', etc.

Die Länge des mittleren, der Zwischenstellung 4' entsprechenden Abschnitts der Rampe 33 sowie der entsprechende Abschnitt des Schwellenhebers 46 sind so bemessen, dass auch Doppelschwellen ohne weiteres gemeinsam aufgenommen, angehoben und auf das Förderband 6a transportiert werden können. In den Figuren 2 bzw. 4 ist eine Doppelschwelle 4a in der Bettung bzw. gestrichelt auf dem Schwellenheber 46 angedeutet.The length of the middle section of the ramp 33 corresponding to the intermediate position 4 'and the corresponding section of the threshold lifter 46 are dimensioned such that double sleepers can also be easily picked up, raised and transported onto the conveyor belt 6a. A double sleeper 4a in the bedding or dashed lines on the sleeper lifter 46 is indicated in FIGS.

In einer zweiten Ausführungsform, die schematisch in Figur 6 dargestellt ist, wird das Mitnehmerorgan durch ein stetig oder intermittierend drehbares Rad 53 mit im betrachteten Beispiel vier gegen die Wirkung von Federn eindrückbaren Schubfingern 54 gebildet, welche gleichmässig über den Radumfang verteilt sind. Die Drehachse dieses Rades 53 ist in den Führungsplatten 26 gelagert und wird in nicht gezeigter Weise von einem Motor angetrieben. Alle übrigen Teile des zweiten Ausführungsbeispiels entsprechen denen des ersten Ausführungsbeispiels, wobei lediglich das Profil der Führungsplatten 26 der Bewegungsbahn der Schwellen angepasst ist.In a second embodiment, which is shown schematically in FIG. 6, the driver element is formed by a wheel 53 which can be rotated continuously or intermittently and, in the example under consideration, four thrust fingers 54 which can be pressed in against the action of springs and which are evenly distributed over the wheel circumference. The axis of rotation of this wheel 53 is mounted in the guide plates 26 and is driven in a manner not shown by a motor. All other parts of the second exemplary embodiment correspond to those of the first exemplary embodiment, only the profile of the guide plates 26 being adapted to the movement path of the sleepers.

Figuren 7 bis 15 zeigen eine dritte, erweiterte Ausführungsform, wobei alle Teile, die denen der Beispiele nach den Figuren 1 bis 6 gleich sind oder diesen Teilen entsprechen, im allgemeinen mit denselben Bezugszeichen bezeichnet sind. Nach den Figuren 7 und 13 hat die Schwellenaufnahmemaschine als Mitnehmerorgan wiederum ein Rad 53, das drei gleichmässig über seinen Umfang verteilte Schubfinger 54a, 54b und 54c aufweist, die gegen die Wirkung von Federn 59 radial nach innen eindrückbar sind. Das Rad 53 sitzt auf einer Welle 55 und ist durch einen Motor 56, insbesondere einen Hydraulikmotor, antreibbar, der an einem Träger 20c des Rahmenteils 20a montiert ist und dessen Drehung über einen Riemen 57 auf ein auf der Welle 55 befestigtes Triebrad 58 (Figur 8) übertragen wird.FIGS. 7 through 15 show a third, expanded embodiment, all parts which are identical to or correspond to those of the examples according to FIGS. 1 to 6 being generally designated by the same reference numerals. According to FIGS. 7 and 13, the sleeper pick-up machine in turn has a wheel 53 which has three thrust fingers 54a, 54b and 54c which are evenly distributed over its circumference and which can be pressed radially inwards against the action of springs 59. The wheel 53 sits on a shaft 55 and can be driven by a motor 56, in particular a hydraulic motor, which is mounted on a carrier 20c of the frame part 20a and whose rotation via a belt 57 onto a drive wheel 58 fastened on the shaft 55 (FIG. 8 ) is transmitted.

Die Rampe 33 ist etwas anders ausgebildet als bei den vorangehenden Beispielen und weist an ihrem dem Rad 53 zugewandten Abschnitt eine aufwärtsgekrümmte, die Anlagefläche für die Schwellen bildende Oberseite 33a auf, die im wesentlichen parallel zum Umfang 53a des Rades 53 verläuft und auf diese Weise mit diesem Radumfang 53a eine aufwärtsgekrümmte Führungsbahn 80 für die Schwellen begrenzt. Im Anschluss an die aufwärtsgekrümmte Oberseite 33a hat die Rampe 33 eine im wesentlichen gerade, leicht entgegengesetzt zur Fahrtrichtung der Maschine geneigte Oberseite 33b.The ramp 33 is constructed somewhat differently than in the preceding examples and has on its section facing the wheel 53 an upwardly curved upper side 33a forming the contact surface for the sleepers, which runs essentially parallel to the circumference 53a of the wheel 53 and in this way also this wheel circumference 53a is bounded by an upwardly curved guideway 80 for the sleepers. Following the upwardly curved upper side 33a, the ramp 33 has a substantially straight upper side 33b which is inclined slightly opposite to the direction of travel of the machine.

An zwei, beiderseits am Rahmenteil 20a befestigten Ansätzen 20d (Figur 8 und 13) ist je eine Führungsschiene 61 derart angeordnet, dass sia wenigstens näherungsweise tangential zum Radumfang 53a, schräg aufwärtsgerichtet, orientiert ist und auf diese Weise die durch den Radumfang 53a gebildete obere Begrenzung der Führungsbahn 80 verlängert. Jede Führungsschiene 61 ist in Bewegungsrichtung der Maschine, also in der Darstellung nach Figur 13 nach links, nachgiebig gelagert, und zu diesem Zwecke einerseits mit ihrem unteren Ende um eine im Ansatz 20d sitzende Achse 63 schwenkbar und andererseits am Ende einer Feder 62 angebracht, deren anderes Ende am Ansatz 20d befestigt ist und die sich unter der Wirkung einer in Bewegungsrichtung der Maschine auf die Führungsschiene 61 wirkenden Kraft komprimieren kann.A guide rail 61 is arranged on two lugs 20d (FIGS. 8 and 13) fastened on both sides to the frame part 20a in such a way that they are oriented at least approximately tangentially to the wheel circumference 53a, obliquely upward, and in this way the upper limit formed by the wheel circumference 53a the guideway 80 extended. Each guide rail 61 is resiliently mounted in the direction of movement of the machine, i.e. to the left in the illustration according to FIG. 13, and for this purpose on the one hand with its lower end pivotable about an axis 63 seated in the projection 20d and on the other hand attached to the end of a spring 62 whose other end is attached to the projection 20d and which can compress under the action of a force acting on the guide rail 61 in the direction of movement of the machine.

Im Bereich des oberen Endes der aufwärtsgekrümmten Oberseite 33a der Rampe 33 sind in der Nähe jeder der beiden vertikalen, diese Rampe 33 bildenden Platten zweiarmige Führungshebel 64 schwenkbar montiert, welche auf einer gemeinsamen horizontalen Achse 65 sitzen, die in den beiden Rampenplatten gelagert ist. Die Führungshebel 64 sind zwischen einer in den Figuren 7 und 13 gezeigten, stark aufwärtsgeneigten Stellung, in welcher sie wenigstens näherungsweise parallel zu den Führungsschienen 61 orientiert sind und damit die untere Begrenzung der Führungsbahn verlängern, und einer in Figur 14 angedeuteten, schwach geneigten Stellung verstellbar, in welcher ihre Oberseite im wesentlichen in der gleichen Ebene wie die Oberseite 33b der Rampe 33 oder etwas unterhalb dieser Oberseite 33b liegt. Zur Verschwenkung der Führungshebel 64 dient je ein in den Figuren 8 und 13 angedeuteter Hydraulikzylinder 66, dessen Gehäuse an der betreffenden Rampenplatte angelenkt ist. Am unteren Hebelarm jedes Führungshebels 64 ist eine unter der Wirkung einer Feder 69 in die Führungsbahn 80 vorspringende Klinke 67 um eine Achse 68 schwenkbar montiert. Diese Klinken 67 dienen dazu, wie später noch beschrieben wird, das Zurückgleiten einer durch einen Schubfinger des Rades 53 in der Führungsbahn bis über die Klinken 67 hinaus verschobenen Schwelle zu verhindern. Durch die Führungsschienen 61 und die in ihrer stark aufwärtsgeneigten Stellung befindlichen Führungshebel 64 wird also die erwähnte Führungsbahn nach oben verlängert, wobei die Führungshebel 64 gleichzeitig die Funktion haben, eine an ihnen anliegende Schwelle in diejenige Zwischenstellung abzusenken, in welcher sie vom Schwellenheber 46 übernommen werden kann, wie es später noch beschrieben wird.In the area of the upper end of the upwardly curved upper side 33a of the ramp 33, two-armed guide levers 64 are pivotally mounted in the vicinity of each of the two vertical plates forming this ramp 33, which are seated on a common horizontal axis 65 which is mounted in the two ramp plates. The guide levers 64 can be adjusted between a position strongly inclined upwards in FIGS. 7 and 13, in which they are oriented at least approximately parallel to the guide rails 61 and thus lengthen the lower boundary of the guideway, and a position slightly inclined as indicated in FIG in which its top is substantially in the same plane as the top 33b of the ramp 33 or slightly below this top 33b. A hydraulic cylinder 66, indicated in FIGS. 8 and 13, is used to pivot the guide lever 64, the housing of which is articulated on the ramp plate in question. On the lower lever arm of each guide lever 64, a pawl 67, which projects into the guide path 80 under the action of a spring 69, is pivotably mounted about an axis 68. As will be described later, these pawls 67 serve to prevent a threshold which has been displaced by a thrust finger of the wheel 53 in the guideway from extending beyond the pawls 67. By means of the guide rails 61 and the guide levers 64 which are in their strongly inclined position, the above-mentioned guide path is thus extended upwards, the guide levers 64 simultaneously having the function of lowering a threshold lying against them into the intermediate position in which they are taken over by the threshold lifter 46 can, as will be described later.

Das durch das Rad 53 gebildete Mitnehmerorgan ist, wie beim ersten Ausführungsbeispiel beschrieben, in vertikaler Richtung nachgiebig an einem Mechanismus aufgehängt, welcher gegenüber der Parallelogrammaufhängung des ersten Ausführungsbeispiels etwas vereinfacht ist. Er besteht nach den Figuren 7 und 13 wiederum aus zwei im wesentlichen horizontal orientierten Armen 24, die mit ihren einen Enden am unteren Ende von Trägern 23 um Achsen 27 und mit ihren anderen Enden an der Welle 55 des Rades 53 angelenkt sind (man vergleiche auch Figur 8) und ausserdem aus zwei Hydraulikzylindern 70, die mit ihren einen Enden am oberen Ende der Träger 23 um die Achsen 28 schwenkbar und mit ihren anderen Enden an einem auf der Walle 55 sitzenden Vorsprung 71 angelenkt sind. Durch geeignete Beaufschlagung der Hydraulikzylinder 70 mit einem vorbestimmten Druck wird eine entsprechend abwärtsgerichtete Kraft auf die Welle 55 und damit das Rad 53 ausgeübt, welches auf diese Weise hinreichend stark gegen den Schotter gepresst wird. Verglichen mit dem Ausführungsbeispiel nach Figur 2 vereinigen also die Hydraulikzylinder 70 in sich die Funktionen der oberen Arme 24 und des Andruckorgans 44.The driver element formed by the wheel 53 is, as described in the first embodiment, resiliently suspended in the vertical direction on a mechanism which is somewhat simplified compared to the parallelogram suspension of the first embodiment. According to FIGS. 7 and 13, it again consists of two essentially horizontally oriented arms 24, which are articulated with their ends at the lower end of supports 23 about axes 27 and with their other ends on the shaft 55 of the wheel 53 (compare also Figure 8) and also from two hydraulic cylinders 70, which are pivotable with their one ends at the upper end of the carrier 23 about the axes 28 and with their other ends to a projection 71 seated on the roller 55. By suitably acting on the hydraulic cylinders 70 with a predetermined pressure, a corresponding downward force is exerted on the shaft 55 and thus on the wheel 53, which in this way is pressed sufficiently strongly against the ballast. Compared to the exemplary embodiment according to FIG. 2, the hydraulic cylinders 70 thus combine the functions of the upper arms 24 and the pressing member 44.

Die beiden den Schwellenheber 46 bildenden Hebel sitzen wiederum auf einer gemeinsamen horizontalen Welle 45, die diesmal jedoch in Ansätzen 20e der Traverse 20b des Maschinenrahmens 20 gelagert ist. Entsprechend sind die hydraulischen Zylinder 47', welche den Schwellenheber46 betätigen und mit den Enden ihrer Kolben an dessen rückwärtigen Enden angelenkt sind, mit ihrem Gehäuse an einem Vorsprung 20f der Traverse 20b schwenkbar befestigt (Figur 7 und 8). Im hinteren Bereich der Oberseite 33b der Rampe 33 sind Ausnehmungen vorgesehen, in welche die Welle 45 eingreift. Im betracteten Beispiel hat der Schwellenheber 46 an den vorderen Enden seiner beiden Herbei teleskopartig ausziehbare Verlängerungsstücke 46a, die, wie schematisch in den Figuren 9 bis 12 veranschaulicht, durch Hydraulikzylinder 77 betätigbar sind. Die verstellbare Länge des Schwellenhebers 46 ist im betrachteten Beispiel deshalb erfoderlich, weil er in seiner abgesenkten Ruhestellung (Figur 7 und 9) nicht in die Führungsbahn 80 eingreifen darf, in seiner angehobenen Stellung jedoch den Abstand zum Förderband 6a überbrücken muss. Daher sind die Verlängerungsstücke 46a in der abgesenkten Ruhestellung eingezogen und in der angehobenen Stellung des Schwellenhebers 46 voll ausgeschoben. Gegebenenfalls kann der Schwellenheber 46 bereits bei der Aufnahme einer durch die Führungshebel 64 abgesenkten Schwelle in seiner unteren Stellung etwas verlängert werden, um einen sicheren Sitz für diese Schwelle zu gewährleisten, wie in Figur 10 veranschaulicht: bei der Aufwärtsbewegung werden dann die Verlängerungsstücke 46a weiter ausgeschoben.The two levers forming the threshold lifter 46 are in turn seated on a common horizontal shaft 45, but this time it is supported in projections 20e of the crossbeam 20b of the machine frame 20. Accordingly, the hydraulic cylinders 47 ', which actuate the threshold lifter 46 and are articulated with the ends of their pistons at the rear ends thereof, are pivotably attached with their housing to a projection 20f of the crossmember 20b (FIGS. 7 and 8). In the rear area of the upper side 33b of the ramp 33, recesses are provided in which the shaft 45 engages. In the example concerned, the threshold lifter 46 has telescopically extendable extension pieces 46a at the front ends of its two ends, which, as schematically illustrated in FIGS. 9 to 12, can be actuated by hydraulic cylinders 77. The adjustable length of the threshold lifter 46 is necessary in the example under consideration because, in its lowered rest position (FIGS. 7 and 9), it must not engage in the guideway 80, but in its raised position it must bridge the distance to the conveyor belt 6a. Therefore, the extension pieces 46a are retracted in the lowered rest position and fully extended in the raised position of the threshold lifter 46. If necessary, the threshold lifter 46 can already be extended somewhat in its lower position when a threshold is lowered by the guide lever 64, in order to ensure a secure fit for this threshold, as illustrated in FIG. 10: the extension pieces 46a are then pushed out further during the upward movement .

Die beiden den Schwellenstösser 49 bildenden Hebel sitzen auf einer gemeinsamen horizontalen Welle 48, die in den Platten der Rampe 33 gelagert ist. Zur Verstellung dienen einerseits an den Rampenplatten und anderseits an den Hebeln des Schwellenstössers 49 angelenke hydraulische Zylinder 50.The two levers forming the threshold pushers 49 sit on a common horizontal shaft 48 which is mounted in the plates of the ramp 33. Articulations are used on the one hand on the ramp plates and on the other hand on the levers of the threshold pusher 49 hydraulic cylinder 50.

Die Funktion der vorstehend beschriebenen Maschine wird anhand der Figuren 9 bis 12 für die Aufnahme und den Transport einer Doppelschwelle 4a erläutert. Das Beispiel einer Doppelschwelle 4s zeigt, dass die Maschine nach der Erfindung ohne weiteres auch Schwellen mit einer Breite handhaben kann, die doppalt so gross wie die normaler Schwellen ist. In den schematischen Figuren 9 bis 12, welche im Prinzip der Ansicht nach Figur 7 entsprechen, sind zur Vereinfachung nur die zum Verständnis der Funktion erforderlichen Teile dargestellt.The function of the machine described above will be explained with reference to FIGS. 9 to 12 for the reception and transport of a double sleeper 4a. The example of a double threshold 4s shows that the machine according to the invention can also easily handle thresholds with a width which is twice as large as the normal thresholds. In the schematic FIGS. 9 to 12, which correspond in principle to the view according to FIG. 7, only the parts necessary for understanding the function are shown for simplification.

Nach Figur 9 ist die in Figur 7 angedeutete Doppelschwelle 4a durch entsprechende Drehung des Rades 53 vom Schubfinger 54a in der Führungsbahn 80 so weit vorgeschoben und angehoben worden, dass sie zwischen den Führungsschienen 61 und den Führungshebeln 64 liegt, jedoch den Bereich der Klinken 67, die beim Vorbeigang der Schwelle eingedrückt werden, noch nicht passiert hat. Gleichzeitig hat sich die Maschine so weit nach vorn bewegt, dass der folgende Schubfinger 54b hinter der als nächstes aufzunehmenden Schwelle 4 liegt, bei der es sich um eine Einzelschwelle handelt. Für den Fall, dass der Schubfinger beim Eintauchen in das Schotterbett bzw. beim Hintergreifen der Schwelle auf einen zu starken Widerstand bzw. ein nur schwer verrückbares Hindernis stösst, wird der betreffende Schubfinger gegen die Wirkung der in Figur 9 angedeuteten Feder 59 eingedrückt, wie in Figur 9 strichpunktiert angedeutet.According to FIG. 9, the double sleeper 4a indicated in FIG. 7 has been advanced and raised by the corresponding pushing of the wheel 53 by the thrust finger 54a in the guide track 80 so that it lies between the guide rails 61 and the guide levers 64, but the area of the pawls 67, that have not yet been pushed in as the threshold passes. At the same time, the machine has moved so far forward that the following thrust finger 54b lies behind the threshold 4 to be picked up next, which is a single threshold. In the event that the thrust finger encounters excessive resistance or an obstacle that is difficult to move when immersed in the ballast bed or when reaching behind the threshold, the push finger in question is pressed in against the action of the spring 59 indicated in FIG. 9, as in Figure 9 indicated by dash-dotted lines.

Ausgehend von der in Figur 9 gezeigten Lage der Doppelschwelle 4a wird diese durch den Schubfinger 54a noch so weit angehoben, dass sie oberhalb der Klinken 67 liegt, die nunmehr unter der Wirkung ihrer Federn 69 wieder nach aussen klappen und dadurch ein eventuelles Zurückgleiten der Doppelschwelle 4a verhindern, wenn der Schubfinger 54a infolge Weiterdrehung des Rades 53 weitergewandert ist. Je nach der Dicke der Schwelle, die sich auf den Führungshebeln 64 abstützt, können die Führungsschienen 61 mehr oder weniger gegen die Wirkung ihrer Federn 62 nachgeben. Nachdem die Doppelschwelle 4a vom Schubfinger 54a hinreichend angehoben wurde, werden die Führungshebel 64 mittels der Hydraulikzylinder 66 im Uhrzeigersinne nach Figur 10 abgesenkt, die eine vorübergehende Stellung der Führungshebel 64 mit der daraufliegenden Doppelschwelle 4a zeigt.Starting from the position of the double sleeper 4a shown in FIG. 9, it is raised so far by the pushing finger 54a that it lies above the pawls 67, which now fold outward again under the action of their springs 69 and thereby a possible sliding back of the double sleeper 4a prevent when the thrust finger 54a has moved due to the further rotation of the wheel 53. Depending on the thickness of the threshold, which is supported on the guide levers 64, the guide rails 61 can yield more or less against the action of their springs 62. After the double sill 4a has been sufficiently raised by the thrust finger 54a, the guide levers 64 are lowered by means of the hydraulic cylinders 66 in a clockwise direction according to FIG. 10, which shows a temporary position of the guide levers 64 with the double sill 4a lying thereon.

Wenn die Führungshebel 64 ihre untere, schwach geneigte Stellung (Figur 14) erreicht haben, in welcher der Boden der Schwelle etwa in Höhe der Oberseite 33b der Rampe 33 und unmittelbar über oder auf dem in seiner unteren Stellung befindlichen Schwellenheber 46 liegt, wird dieser Schwellenheber aufwärtsverschwenkt. um die Schwelle bis in die Höhe des Förderbandes 6a anzuheben. Figur 11 zeigt eine Lage kurz vor Erreichen dieser Stellung. Unmittelbar vor Absenkung einer Schwelle auf den in seiner unteren Lage befindlichen Schwellenheber 46 werden dessen Verlängerungsstücke 46a, falls erforderlich, soweit ausgefahren, dass die Doppelschwelle 4a möglichst über ihre gesamte Breite auf dem Schwellenheber 46 abgesetzt wird und daher beim Anheben sicher auf diesem liegt. In der in Figur 11 gezeigten oberen Stellung der Schwellenhebers 46 sind dessen Verlängerungsstücke 46a voll ausgefahren, um den Abstand zum Förderband 6a zu überbrücken. Während des Hebens der Schwelle durch den Schwellenheber46 dreht das Rad 53 unter Mitnahme der folgenden Schwelle 4 durch den Schubfinger 54b weiter, und gleichzeitig werden die Führungshebel 64 wieder in ihre stark aufwärts geneigte Ausgangsstellung rückverschwenkt,When the guide levers 64 have reached their lower, slightly inclined position (FIG. 14), in which the bottom of the threshold lies approximately at the top 33b of the ramp 33 and immediately above or on the threshold lifter 46 in its lower position, this threshold lifter becomes pivoted upwards. to raise the threshold to the height of the conveyor belt 6a. Figure 11 shows a situation shortly before reaching this position. Immediately before a threshold is lowered onto the threshold lifter 46 located in its lower position, its extension pieces 46a are extended, if necessary, to such an extent that the double threshold 4a is deposited on the threshold lifter 46 as far as possible over their entire width and therefore lies securely on the latter when it is lifted. In the upper position of the threshold lifter 46 shown in FIG. 11, its extension pieces 46a are fully extended in order to bridge the distance to the conveyor belt 6a. During the raising of the threshold by the threshold lifter 46, the wheel 53 continues to rotate, taking the following threshold 4 with it, by the thrust finger 54b, and at the same time the guide levers 64 are pivoted back again into their strongly upwardly inclined starting position,

Nachdem der Schwellenheber 46 seine oberste, in Figur 12 gezeigte Stellung erreicht hat, tritt der Schwellenstösser 49 in Funktion und stösst die Doppelschwelle 4a auf das Förderband 6a. In der Zwischenzeit haben die Führungshebel 64 wieder ihre obere, stark aufwärts geneigte Stellung erreicht, so dass die folgende Schwelle 4 bei Weiterdrehung des Rades 53 zwischen die Führungsschienen 61 und die Führungshebel 64 gelangen kann und sich der beschriebene Zyklus wiederholt. Sobald die Doppelschwelle 4a vom Förderband 6a übernommen worden ist, wird der Schwellenheber 46, unter gleichzeitiger Einziehung seiner Verlängerungsstücke 46a, wieder in seine abgesenkte Ruhelage und der Schwellenstösser 49 zurück in seine Ausgangsstellung verschwenkt.After the threshold lifter 46 has reached its uppermost position, shown in FIG. 12, the threshold pusher 49 comes into operation and pushes the double threshold 4a onto the conveyor belt 6a. In the meantime, the guide levers 64 have again reached their upper, strongly inclined position, so that the following threshold 4 can pass between the guide rails 61 and the guide levers 64 when the wheel 53 continues to rotate and the cycle described is repeated. As soon as the double sleeper 4a has been taken over by the conveyor belt 6a, the sleeper lifter 46, with the simultaneous retraction of its extension pieces 46a, is pivoted back into its lowered rest position and the sleeper pusher 49 is pivoted back into its initial position.

Die vorstehend beschriebene Ausführungsform einer Schwellenaufnabmemaschine erlaubt es, die aus dem Schotterbett harausgehobenen Schwellen dank der Führungsbahn 80 besonders sicher aufwärts zu führen und dann durch Absenkung der Führungshebel 64 in diejenige Zwischenstellung zu überführen, aus der heraus sie vom Schwellenheber 46 in der zum Weitertransport zweckmässigen Orientierung angehoben werden können. Dabei sind im Prinzip die eindrückbaren Klinken 67 nicht erforderlich, da ja zum hinreichenden Anheben einer Schwelle und zur Verhinderung ihres Zurückfallens der die Schwelle stossende Schubfinger des Rades 53 genügt und die Führungshebel 64 mit der Schwelle abgesenkt werden können, bevor der betreffende Schubfinger beim Weiterdrehen des Rades 53 von der Schwelle abrutscht. Die Klinken 67 bieten jedoch im allgemeinen eine grössere Betriebssicherheit und erlauben es vor allem, zwei nacheinander in den Raum zwischen den Führungsschienen 61 und den Führungshebeln 64 transportierte Einzelschwellen anschliessend gemeinsam durch die Führungshebel 64, den Schwellenheber 46 und schliesslich den Schwellenstösser 49 auf das Förderband 6a zu transportieren. Bei dieser Arbeitsweise wird so vorgegangen, dass zunächst eine Einzelschwelle bis über die Klinken 67 angehoben und dann durch die unter diese Schwelle greifenden Klinken gehalten wird und danach, ohne dass die Führungshebel 64 betätigt werden, vom folgenden Schubfinger eine zweite Einzelschwelle so weit angehoben wird, bis sie, unter Mitnahme und weiterer Anhebung der ersten Schwelle, die Höhe der Führungshebel 64 erreicht hat, so dass sich nunmehr beide übereinanderliegenden Schwellen an den Führungshebeln 64 abstützen, welche daraufhin abgesenkt werden. Nach dieser Arbeitsweise lässt sich mit nur der halben Frequenz der Arbeitszyklen der Teile 64, 46 und 49 die gleiche Anzahl von Schwellen je Zeiteinheit entfernen und abtransportieren.The above-described embodiment of a sleeper pick-up machine allows the sleepers lifted out of the ballast bed to be guided upwards in a particularly secure manner thanks to the guideway 80 and then by lowering the guide levers 64 to transfer them to the intermediate position from which they are removed from the sleeper lifter 46 in the orientation suitable for further transport can be raised. In principle, the pawls 67 that can be pushed in are not required, since the thrust finger pushing the threshold 53 of the wheel 53 is sufficient to sufficiently raise a threshold and to prevent it from falling back, and the guide lever 64 can be lowered with the threshold before the thrust finger in question when turning the Wheel 53 slips off the threshold. However, the pawls 67 generally offer greater operational reliability and, above all, allow two individual sleepers, which are successively transported into the space between the guide rails 61 and the guide levers 64, together through the guide levers 64, the sleeper lifter 46 and finally the sleeper pushers 49 onto the conveyor belt 6a to transport. In this way of working, the procedure is such that first a single threshold is raised to above the pawls 67 and then by those reaching under this threshold Is held pawls and then, without the guide lever 64 being actuated, a second single threshold is raised by the following thrust finger until it has reached the height of the guide lever 64, taking the first threshold with it and raising it further, so that both now move Support overlying sleepers on the guide levers 64, which are then lowered. According to this method of operation, the same number of thresholds per unit of time can be removed and removed with only half the frequency of the working cycles of parts 64, 46 and 49.

Beim Betrieb der Maschine kann, während diese sich gleichförmig vorbewegt, das Rad 53 im allgemeinen gleichförmig gedreht werden, es ist gegebenenfalls jedoch auch eine schrittweise oder eine entsprechend den Arbeitsbedingungen ungleichförmige Drehung möglich.While the machine is operating, while the wheel is advancing uniformly, the wheel 53 can generally be rotated uniformly, but it may also be possible to perform a stepwise rotation or a nonuniform rotation depending on the working conditions.

Die ganze Rampe 33 mit den daran befestigen Teilen kann um die Achse 82, die in Ansätzen 20g der Traverse 20b (Fig.8) gelagert ist, in der Darstellung nach Figur 7 entgegengesetzt zum Uhrzeigersinne hochgeschwenkt werden. Zu diesem Zwecke ist ein Hydraulikzylinder 81 einerseits am hinteren Bereich der Rampe 33 und andererseits an einem Ansatz 20h der Traverse 20b angelenkt. Auf diese Weise lässt sich die Rampe 33 mit Hilfe des Hydraulikzylinders 81 einerseits in der Höhe einstellen und andererseits nach Beendigung der Arbeiten aus dem Schotterbett heraus- und in eine Ruhestellung, insbesondere für Ueberführungsfshrten in einem Zugsverband, anheben,The entire ramp 33 with the parts attached to it can be pivoted counterclockwise about the axis 82, which is supported in the shoulders 20g of the crossbeam 20b (FIG. 8), in the illustration according to FIG. For this purpose, a hydraulic cylinder 81 is articulated on the one hand on the rear area of the ramp 33 and on the other hand on an extension 20h of the crossbeam 20b. In this way, the ramp 33 can be adjusted in height with the aid of the hydraulic cylinder 81 and, on the other hand, can be lifted out of the ballast bed and raised to a rest position, in particular for transfer guards in a train, on the other hand,

Um eine seitliche Ausrichtung der aus dem Schotterbett herausgehobenen Schwellen 4 zu gewährleisten, ist die zuletzt beschriebene Maschine zweckmässigerweise noch mit einer Schwellenausrichteinrichtung ausgerüstet, die schematisch in den Figuren 15 und 16 und ausserdem in Figur 8 angedeutet ist, während sie in der Darstellung nach Figur 7 aus Gründen der Uebersichtlichkeit weggelassen wurde. Diese Einrichtung weist an beiden Seiten der Maschine je eine im wesentlichen vertikal orientierte, leicht nach aussen gebogene Platte 72 auf, die an der betreffenden Seite des Maschinenrahmens 20 um eine in Längsrichtung orientierte Achse 74 im Sinne des Doppelpfeils nach Figur 16 schwenkbar gelagert ist. Mit Hilfe eines Hydraulikzylinders 73, der einerseits am Maschinenrahmen 20 um die Achse 75 schwenkbar und andererseits an einem nach innen gerichteten Vorsprung der Platte 72 um die Achse 76 schwenkbar montiert ist, lässt sich jede Platte aus der in Figur 16 gestrichelt dargestellten, etwas nach aussen verschwenkten Ruhelage in die mit ausgezogenen Linien gezeichnete Lage nach innen verstellen, sobald eine Schwelle 4 aus dem Schotter herausgehoben und in der Führungsbahn 80 nach oben bewegt wird. Auf diese Weise wird eine in Figur 15 und 16 gestrichelt dargestellte, in Bezug auf die Symmetrie-Längsachse der Maschine seitlich versetzte Schwelle 4 bei ihrer Aufwärtsbewegung durch die Platten 72 zur Mitte hin in ihre zentrierte Lage verschoben, wie es für die mit durchgehenden Linien dargestellteIn order to ensure a lateral alignment of the sleepers 4 lifted out of the ballast bed, the machine described last is expediently also equipped with a sleeper alignment device, which is indicated schematically in FIGS. 15 and 16 and also in FIG. 8, while in the illustration according to FIG. 7 was omitted for reasons of clarity. This device has on each side of the machine an essentially vertically oriented, slightly outwardly curved plate 72 which is mounted on the relevant side of the machine frame 20 so as to be pivotable about an axis 74 oriented in the longitudinal direction in the sense of the double arrow according to FIG. With the help of a hydraulic cylinder 73, which is pivotable on the one hand on the machine frame 20 about the axis 75 and on the other hand pivotably mounted on an inward projection of the plate 72 about the axis 76, each plate can be moved somewhat outwards from the one shown in dashed lines in FIG Adjust the pivoted rest position into the position drawn with solid lines inwards as soon as a sleeper 4 is lifted out of the ballast and moved upwards in the guideway 80. In this way, a threshold 4 shown in dashed lines in FIGS. 15 and 16, laterally offset with respect to the longitudinal axis of symmetry of the machine, is displaced toward its center in its centered position during its upward movement by the plates 72, as is shown for those with solid lines

Schwelle 4 gezeigt ist. Auf diese Weise wird gewährleistet, dass die Schwellen in seitlich ausgerichteter bzw. zentrierter Lage auf das Förderband 6a gelangen.Threshold 4 is shown. This ensures that the sleepers reach the conveyor belt 6a in a laterally aligned or centered position.

Figur 17 zeigt eine vierte Ausführungsform, die sich von der anhand der Figuren 7 bis 16 dargestellten Ausführungsform lediglich dadurch unterscheidet, dass das Mitnehmerorgan 83 - wie im Beispiel nach den Figuren 2 bis 5 - eine hin-und herdrehende Bewegung um die Welle 55 im Sinne des Doppelpfeils ausführt und die Form eines Kreisscheibensegments hat, das etwas grösser als eine halbe Scheibe ist. Es kann jedoch auch die ungefähre Form eines Kreissektors haben, der sich über einen Winkel kleiner als 180° erstreckt. Dieses Nitnehmerorgan 83 ist. wie im Falle des ersten Ausführungsbeispiels, mit einem einzigen Schubfinger 84 ausgerüstet, der mittels eines hydraulischen Zylinders 85 zwischen der in Figur 17 gestrichelt dargestellten, ausgezogenen Arbeitsstellung und der mit durchgehenden Linien gezeichneten eingezogenen Ruhestellung verstellbar ist, wie es beim ersten Ausführungsbeispiel für den durch den hydraulischen Zylinder 40 betätigbaren Schubfinger 32 erläutert wurde. Zum hin- und hergehenden Antrieb des Mitnehmerorgans 83 dient ein Hydraulikzylinder 86, der einerseits am Träger 20c der vorderen Seite 20a des Maschinenrahmens 20 und andererseits an einem auf der Welle 55 sitzenden Ansatz 87 angelenkt ist. Zum Herausheben und Anheben einer Schwelle wird das Mitnehmerorgan 83 bei ausgezogenem, die Schwelle hintergreifenden Schubfinger 84 im Sinne des Pfeils nach Figur 17 im Uhrzeigersinne bis in die gestrichelt dargestellte Lage gedreht, wobei der in Schubrichtung vor dem Schubfinger 84 liegende Umfangsbereich 83a des Mitnehmerorgans die obere Begrenzung der erwähnten Führungsbahn 80 bildet. Anschliessend wird die Schwelle durch die (in Figur 17 nicht gezeigten) Führungshebel 64 abgesenkt und so weiter transportiert, wie es anhand der Figuren 7 bis 12 erläutert wurde. Alle übrigen, nicht in Figur 17 dargestellten Teile dieses vierten Ausführungsbeispiels der Maschine und ihre Funktionen entsprechen denen des dritten Ausführungsbeispiels nach den Figuren 7 bis 16. Dazu gehören insbesondere die erwähnte Führungsbahn 80, die Führungsschienen 61, die Führungshebel 64, der Schwellenheber 46 und der Schwellenstosser 49 sowie die gelenkige Aufhängung des Mitnehmerorgans 83 mittels der Arme 24 und der Hydraulikzylinder 70 nach Figur 13.FIG. 17 shows a fourth embodiment, which differs from the embodiment shown on the basis of FIGS. 7 to 16 only in that the driver element 83 - as in the example according to FIGS. 2 to 5 - has a back and forth movement around the shaft 55 in the sense of the double arrow and has the shape of a circular disk segment that is slightly larger than half a disk. However, it can also have the approximate shape of a sector of a circle which extends over an angle of less than 180 °. This Nitnehmerorgan 83 is. as in the case of the first embodiment, equipped with a single thrust finger 84, which can be adjusted by means of a hydraulic cylinder 85 between the extended working position shown in dashed lines in FIG. 17 and the retracted rest position drawn with solid lines, as in the first embodiment for the by the hydraulic cylinder 40 actuatable thrust finger 32 was explained. A hydraulic cylinder 86, which is articulated on the one hand on the carrier 20c of the front side 20a of the machine frame 20 and on the other hand on a shoulder 87 seated on the shaft 55, serves for the reciprocating drive of the driving element 83. To lift and raise a threshold, the driver element 83 is rotated clockwise into the position shown in dashed lines in the direction of the arrow according to FIG Limitation of the mentioned guideway 80 forms. The threshold is then lowered by the guide lever 64 (not shown in FIG. 17) and transported as described with reference to FIGS. 7 to 12. All other parts of this fourth exemplary embodiment of the machine, not shown in FIG. 17, and their functions correspond to those of the third exemplary embodiment according to FIGS. 7 to 16. These include, in particular, the aforementioned guide track 80, the guide rails 61, the guide lever 64, the sleeper lifter 46 and the Threshold bumpers 49 and the articulated suspension of the driving element 83 by means of the arms 24 and the hydraulic cylinders 70 according to FIG. 13.

Die beschriebene Schwellenaufnahmemaschine nach der Erfindung erlaubt es, dass die auf der Maschine befindliche, die Arbeiten beobachtende Bedienungsperson von Hand die Arbeitsbewegungen des Mitnehmerorgans 31 bzw. 53 bzw. 83 steuert, welche auf diese Weise - bei gleichförmiger Vorschubgeschwindigkeit der Maschine-individuell den häufig variierenden Schwellenabständen sowie auch ohne weiteres den häufig auftretenden Doppelschwellen angepasst werden können. Die Steuerung des Schwellenhebers 46 und des Schwellenstössers 49 sowie, falls vorhanden, der Führungshebel 64 kann dann im allgemeinen zweckmässigerweise in Abhängigkeit von der handgesteuerten Bewegung des Mitnehmerorgans automatisch erfolgen. Da die individuell steuerbare Verschiebung der Schwellen aus der Bettung auf die Rampe 33, das Anheben der Schwellen und schliesslich die Verschiebung der angehobenen Schwellen auf das Förderband durch getrennte Organe erfolgen, ist ein Verklemmen der Schwellen praktisch ausgeschlossen und eine störungsfreie Aufnahme von Schwellen aller Art, unabhängig von deren Zustand und vom Zustand der Gleisbettung, auf geraden Gleisabschnitten wie auch in Kurvenabschnitten sichergestellt. So können ohne Arbeitsunterbrechung Schwellen unterschiedlichen Materials, wie Holz-, Beton-und Stahlschwellen, aufgenommen werden. Ausserdem werden die Schwellen bei ihrem Transport auf das Forderband nicht umgedreht, so dass die auf der Oberseite der Schwellen befestigten Unterlags- bzw. Rippenplatten auch bei den auf das Förderband gelangenden Schwellen oben liegen; somit entfällt die Notwendigkeit eines späteren Wendens der Schwellen, bevor diese in üblicher Weise auf einer Plattform zum Weitertransport gesammelt werden. Die Schwellen liegen auf diese Weise auch wesentlich sicherer auf dem Förderband. Durch die gegebenenfalls vorzusehenden Führungsplatten 26 bzw. die Schwellenausrichteinrichtung nach Figur 15 und 16, wird ausserdem, wie erläutert, die seitliche Führung der Schwellen bzw. ihre Zentrierung bei der Verschiebung auf der Rampe 33 bzw. eine definierte Führung beim Anheben gewährleistet.The described threshold recording machine according to the invention allows the operator on the machine to observe the work by hand Controls working movements of the driving member 31 or 53 or 83, which can be adjusted in this way - with a uniform feed speed of the machine - individually to the frequently varying threshold distances and also easily to the frequently occurring double thresholds. The control of the threshold lifter 46 and the threshold pusher 49 and, if present, the guide lever 64 can then in general expediently take place automatically as a function of the hand-controlled movement of the driver element. Since the individually controllable shifting of the sleepers from the bed onto ramp 33, the lifting of the sleepers and finally the shifting of the raised sleepers onto the conveyor belt are carried out by separate organs, jamming of the sleepers is practically impossible and trouble-free reception of sleepers of all kinds, regardless of their condition and the condition of the track bed, ensured on straight track sections as well as in curve sections. In this way, sleepers of different materials, such as wooden, concrete and steel sleepers, can be picked up without interrupting work. In addition, the sleepers are not turned over during their transport onto the conveyor belt, so that the underlay or ribbed plates attached to the upper side of the sleepers are also at the top of the sleepers reaching the conveyor belt; this eliminates the need to turn the sleepers later before they are collected in the usual way on a platform for onward transport. In this way, the sleepers are much safer on the conveyor belt. The guide plates 26 or the threshold alignment device according to FIGS. 15 and 16, which may be provided, also ensure, as explained, the lateral guidance of the sleepers or their centering during displacement on the ramp 33 or a defined guidance when lifting.

Die Erfindung ist nicht auf die beschriebenen Ausführungsbeispiele beschränkt, sondern lässt hinsichtlich der Ausbildung und Anordnung des Mitnehmerorgans sowie der anderen, die Schwellen bewegenden Teile und der Form und Ausbildung der Rampe sowie der Führungsbahn für die Schwellen mannigfache Varianten zu.The invention is not limited to the exemplary embodiments described, but rather allows for a wide variety of variants with regard to the design and arrangement of the driver element and the other parts moving the sleepers and the shape and design of the ramp and the guideway for the sleepers.
