Definitions

  • the invention relates to a trestle for semitrailers to be transported on railway carriages with a fifth wheel receiving the fifth wheel of the semitrailer, a downward pointing kingpin and a lock for fixing the trestle on the railroad car.
  • the semi-trailer During normal use of the semi-trailer in road traffic, its front part rests on the tractor's saddle and is centered with the kingpin. If the semitrailer is to be parked without a tractor, it is unsaddled, that is, placed on its own parking supports, which are arranged behind the kingpin outside the tractor area under the semitrailer. These own parking supports, which can be adjusted in length by means of hand mechanisms and are placed on the road with rollers or plates, are sufficient for the safe parking of the semi-trailer on streets and squares.
  • the semitrailer at the loading station is driven by a tractor onto the railway wagons called piggyback wagons, on which the semitrailer is transported without the tractor.
  • the semitrailer is then lowered from the piggyback truck by another tractor and carried on the road.
  • the semi-trailers' own parking supports do not meet the safety requirements for transport on other means of transport, for example on piggyback trucks.
  • the semitrailers are subjected to violent shocks in the longitudinal direction of the vehicle due to maneuvering acceleration and braking deceleration forces and corresponding cross-shocks when cornering and turning. These loads cannot be adequately absorbed by the parking supports mentioned. It is therefore common in piggyback traffic to use trestles instead of the parking supports to support the front end of the semi-trailer in order to be able to transport it safely on the piggyback truck.
  • the known trestles consist of racks carried on the piggyback truck, which have a fifth wheel on their upper side for saddling the semi-trailer by means of its kingpin.
  • the trestles are either fixedly arranged on the piggyback car or movable and provided with a locking device for fixing on the piggyback car. It is further known to guide the movable or longitudinally displaceable trestles in running or guide rails on the piggyback trolley and to fix them at the desired or required location on the piggyback trolley by means of a locking device.
  • the number of trestles required for a complete loading of the piggyback truck is always carried on the piggyback truck.
  • the trestles To load the piggyback wagon with the semitrailer, the trestles must be able to be driven over, that is to say so that they can be collapsed in such a way that they do not hinder the vehicles from entering or leaving the wagon.

  • a disadvantageous tilting moment arises during use in that the kingpin and the fifth wheel coupling, to which significant vertical forces act, are at a horizontal distance from one another.
  • a remedy must be omitted simply because the tractor cannot go deep enough into the trestle because of the cross rib.
  • the invention is based on the object of finding a trestle which makes the entire loading and unloading process time-saving and more economical by better distribution of forces, which simplifies the fixing of the semi-trailer on the piggyback truck and which is economical to manufacture and does not require any complex components.

Description

Die Erfindung betrifft einen Stützbock für auf Eisenbahnwagen zu transportierende Sattelauflieger mit einer den Zugsattelzapfen des Sattelaufliegers aufnehmenden Sattelkupplung, einem nach unten weisenden Zugsattelzapfen und einer Verriegelung zur Festlegung des Stützbocks auf dem Eisenbahnwagen.The invention relates to a trestle for semitrailers to be transported on railway carriages with a fifth wheel receiving the fifth wheel of the semitrailer, a downward pointing kingpin and a lock for fixing the trestle on the railroad car.

Bei der normalen Verwendung des Sattelaufliegers im Straßenverkehr liegt dieser mit seinem Vorderteil auf dem Sattel der Zugmaschine auf und wird mit dem Zugsattelzapfen zentriert. Wenn der Sattelauflieger ohne Zugmaschine abgestellt werden soll, wird er abgesattelt, das heißt auf eigene Abstellstützen gesetzt, die hinter dem Zugsattelzapfen außerhalb des Zugmaschinenbereiches unter dem Sattelauflieger angeordnet sind. Diese eigenen, durch Handmechanismen längenveränderlichen und mit Laufrollen oder Platten auf der Fahrbahn stehenden Abstellstützen genügen zur sicheren Abstellung des Sattelaufliegers auf Straßen und Plätzen.During normal use of the semi-trailer in road traffic, its front part rests on the tractor's saddle and is centered with the kingpin. If the semitrailer is to be parked without a tractor, it is unsaddled, that is, placed on its own parking supports, which are arranged behind the kingpin outside the tractor area under the semitrailer. These own parking supports, which can be adjusted in length by means of hand mechanisms and are placed on the road with rollers or plates, are sufficient for the safe parking of the semi-trailer on streets and squares.

Bei dem Transport von Sattelauflieger im Huckepack-Verkehr auf Schienenfahrzeugen wird der Sattelauflieger am Verladebahnhof von einer Zugmaschine auf die Huckepackwagen genannten Eisenbahnwagen gefahren, auf denen der Sattelauflieger ohne die Zugmaschine befördert wird. Am Bestimmungsbahnhof wird der Sattelauflieger dann von einer anderen Zugmaschine vom Huckepackwagen herunter gefahren und auf der Straße weiterbefördert.When transporting semitrailers in piggyback transport on rail vehicles, the semitrailer at the loading station is driven by a tractor onto the railway wagons called piggyback wagons, on which the semitrailer is transported without the tractor. At the destination station, the semitrailer is then lowered from the piggyback truck by another tractor and carried on the road.

Die eigenen Abstellstützen des Sattelaufliegers genügen nicht den Sicherheitsanforderungen für den Transport auf anderen Transportmitteln, zum Beispiel auf Huckepackwagen. In diesen Fällen sind die Sattelauflieger durch Rangier-Beschleunigungs- und Bremsverzögerungskräfte heftigen Stößen in Fahrzeuglängsrichtung und beim Befahren von Kurven und Weichen entsprechenden Querstößen ausgesetzt. Diese Beanspruchungen können nicht von den erwähnten Abstellstützen ausreichend sicher abgefangen werden. Es ist deshalb im Huckepack-Verkehr üblich, Stützböcke anstelle der Abstellstützen zur Auflage des vorderen Endes des Sattelaufliegers zu verwenden, um diesen sicher auf dem Huckepackwagen befördern zu können.The semi-trailers' own parking supports do not meet the safety requirements for transport on other means of transport, for example on piggyback trucks. In these cases, the semitrailers are subjected to violent shocks in the longitudinal direction of the vehicle due to maneuvering acceleration and braking deceleration forces and corresponding cross-shocks when cornering and turning. These loads cannot be adequately absorbed by the parking supports mentioned. It is therefore common in piggyback traffic to use trestles instead of the parking supports to support the front end of the semi-trailer in order to be able to transport it safely on the piggyback truck.

Die bekannten Stützböcke bestehen dabei aus auf dem Huckepackwagen mitgeführten Gestellen, die auf ihrer Oberseite eine Sattelkupplung zum Aufsatteln des Sattelaufliegers mittels dessen Zugsattelzapfen aufweisen. Die Stützböcke sind dabei entweder auf dem Huckepackwagen fest angeordnet oder verfahrbar und mit einer Verriegelungseinrichtung zur Festlegung auf dem Huckepackwagen versehen. Es ist weiter bekannt, die verfahrbaren oder auf dem Huckepackwagen längsverschiebbaren Stützböcke in Lauf- oder Führungsschienen zu führen und an der gewünschten oder erforderlichen Stelle auf dem Huckepackwagen mittels einer Verriegelungseinrichtung festzulegen.The known trestles consist of racks carried on the piggyback truck, which have a fifth wheel on their upper side for saddling the semi-trailer by means of its kingpin. The trestles are either fixedly arranged on the piggyback car or movable and provided with a locking device for fixing on the piggyback car. It is further known to guide the movable or longitudinally displaceable trestles in running or guide rails on the piggyback trolley and to fix them at the desired or required location on the piggyback trolley by means of a locking device.

In diesen Fällen wird die für eine vollständige Beladung des Huckepackwagens erforderliche Anzahl von Stützböcken auf dem Huckepackwagen stets mitgeführt. Zum Beladen des Huckepackwagens mit dem Sattelanhänger müssen die Stützböcke überfahrbar sein, das heißt, so zusammenlegbar, daß sie das Auf- oder Abfahren der Fahrzeuge auf den Waggon nicht behindern. Dieses erfordert eine komplizierte, unwirtschaftliche und mit vielen beweglichen Teilen versehene und somit störanfällige Konstruktion der Stützböcke.In these cases, the number of trestles required for a complete loading of the piggyback truck is always carried on the piggyback truck. To load the piggyback wagon with the semitrailer, the trestles must be able to be driven over, that is to say so that they can be collapsed in such a way that they do not hinder the vehicles from entering or leaving the wagon. This requires a complicated, uneconomical and provided with many moving parts and therefore prone to failure construction of the trestles.

Schließlich ist durch die US-A-3 603 544 ein Stützbock bekannt, der kastenförmig ausgebildet und innen mit einer Querrippe aus nur teilweise durchbrochenem Blech versehen ist sowie einen lotrechten Zugsattelzapfen aufweist, der in Fahrtrichtung des Sattelaufliegers vor der Sattelkupplung angeordnet ist. Bei dieser Konstruktion entsteht ein nachteiliges Kippmoment während des Gebrauchs dadurch, daß der Zugsattelzapfen und die Sattelkupplung, an denen maßgebende vertikale Kräfte angreifen, einen horizontalen Abstand voneinander haben. Eine Abhilfe muß schon deshalb unterbleiben, weil die Zugmaschine wegen der Querrippe nicht tief genug in den Stützbock einfahren kann.Finally, a support bracket is known from US-A-3 603 544, which is box-shaped and is provided on the inside with a transverse rib made of only partially perforated sheet metal and has a vertical king pin, which is arranged in the direction of travel of the semi-trailer in front of the fifth wheel coupling. In this construction, a disadvantageous tilting moment arises during use in that the kingpin and the fifth wheel coupling, to which significant vertical forces act, are at a horizontal distance from one another. A remedy must be omitted simply because the tractor cannot go deep enough into the trestle because of the cross rib.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Stützbock zu finden, der den gesamten Be-und Entladevorgang zeitsparend und durch bessere Kräfteverteilung wirtschaftlicher gestaltet, der die Festlegung des Sattelaufliegers auf dem Huckepackwagen vereinfacht und der in seiner Herstellung wirtschaftlich ist und ohne aufwendige Bauteile auskommt.The invention is based on the object of finding a trestle which makes the entire loading and unloading process time-saving and more economical by better distribution of forces, which simplifies the fixing of the semi-trailer on the piggyback truck and which is economical to manufacture and does not require any complex components.

Diese Aufgabe der Erfindung wird bei einem Stützbock der eingangs genannten Art dadurch gelöst, daß der Stützbock in Form einer Traverse oder eines Portals ausgebildet ist und den Zugsattelzapfen zentrisch unterhalb der Sattelkupplung aufweist und mit Führungen zum vertikalen Einführen in den Eisenbahnwagen ausgerüstet ist.This object of the invention is achieved in a trestle of the type mentioned in that the trestle is designed in the form of a cross member or a portal and has the kingpin centrally below the fifth wheel coupling and is equipped with guides for vertical insertion into the railroad car.

Durch die erfindungsgemäße Ausbildung des Stützbocks wird erreicht, daß die üblicherweise zum rationellen Beladen auf dem Verladebahnhof auf ihren Abstellstützen abgestellten Sattelauflieger ohne großen Zeit- und Arbeitsaufwand auf den Huckepackwagen verladen werden können. Eine einzige, auf dem Verladebahnhof vorgehaltene Zugmaschine fährt mit ihrer Sattelplatte unter einen ebenfalls auf dem Verladebahnhof vorgehaltenen Stützbock und rastet die Sattelkupplung selbsttätig in den Zugsattelzapfen des Stützbocks ein. Mit diesem so aufgesattelten Stützbock fährt die Zugmaschine anschließend unter den abgestellten Sattelauflieger und sattelt diesen ebenfalls selbsttätig auf den Stützbock auf. Über die in der Regel hydraulisch betätigte Anhebevorrichtung der Sattelkupplung der Zugmaschine wird der Sattelauflieger angehoben und die Zugmaschine rangiert den Sattelauflieger mit dem Stützbock rückwärts auf den Huckepackwagen auf. In etwa der vorgesehenen Beladestellung des Sattelaufliegers senkt die Zugmaschine das aufgesattelte Ende des Sattelaufliegers ab, wobei der Stützbock über seine Führungselemente geführt in die Führungen des Huckepackwagens abgesetzt wird und dabei den Sattelauflieger in die vorgesehene Beladestellung zentriert. Auf dem Huckepackwagen brauchen somit keine Stützböcke mitgeführt werden. Diese sind auf der Verladeanlage bevorratet und werden lediglich bei Bedarf eingesetzt. Vorteilhaft entfällt weiter das umständliche Niederlegen und Aufrichten des Stützbocks auf dem Huckepackwagen. Dadurch, daß der Stützbock in Form einer Traverse oder eines Portals ausgebildet ist, kann die Zugmaschine ungehindert mit ihrer Sattelkupplung unter den Stützbock fahren und diesen aufsatteln. Die Anordnung eines Zugsattelzapfens einer Sattelkupplung unter dem Stützbock bzw. unter der Sattelkupplung des Stückbocks ermöglicht außerdem das selbsttätige Aufsatteln des Stützbocks und mit diesem das Aussatteln des Sattelaufliegers, was eine wesentliche Vereinfachung des Beladevorganges bildet. Bei auf den Huckepackwagen verfahrenem Sattelauflieger übernehmen die Führungselemente des Stützbocks das Zentrieren des Sattelaufliegers und des Stützbocks in eine vorgesehene Beladestellung des Sattelaufliegers, wodurch ebenfalls eine wesentliche Vereinfachung des Beladevorgangs gewährleistet wird.The inventive design of the trestle ensures that the semitrailers usually parked on their parking supports for efficient loading at the loading station can be loaded onto the piggyback wagon without great expenditure of time and effort. A single tractor held at the loading station travels with its saddle plate under a support frame that is also located at the loading station and automatically engages the fifth wheel in the kingpin of the support frame. With this support frame, the tractor then drives under the parked semi-trailer and also saddles it automatically onto the support frame. About the usually hydraulically operated lifting device of the fifth wheel coupling of the tractor unit, the semi-trailer is raised and the tractor unit mounts the semi-trailer with the support frame backwards onto the piggyback vehicle. In about the intended loading position of the semi-trailer, the tractor lowers the semi-trailer end of the semi-trailer, the support frame being guided over its guide elements into the guides of the piggyback wagon, centering the semi-trailer in the intended loading position. No trestles need to be carried on the piggyback truck. These are stored on the loading system and are only used when required. The cumbersome laying down and erecting of the support frame on the piggyback car is also advantageously eliminated. Characterized in that the support frame is designed in the form of a traverse or a portal, the tractor can drive unhindered with its fifth wheel under the support frame and saddle it up. The arrangement of a king pin of a fifth wheel coupling under the trestle or under the fifth wheel coupling of the trestle also enables the support frame to be automatically saddled and with it the saddle-up of the semitrailer, which considerably simplifies the loading process. In the case of a semi-trailer moved on the piggyback truck, the guide elements of the support frame take over the centering of the semi-trailer and the support frame in a planned loading position of the semi-trailer, which likewise ensures a significant simplification of the loading process.

Der Stützbock ist mit seinen Querenden im Bereich der Seitenlangträger des Eisenbahnwagens auf diesem oder dessen Seitenlangträgern abgestützt. Da Huckepackwagen üblicherweise mit sehr niedriger Ladefläche ausgelegt sind, ist im Bereich der Ladefläche die Anordnung von entsprechenden Führungen oder Halterungen für den Stützbock schlecht möglich. Vorteilhaft wird bei der Ausführung gemäß vorliegender Erfindung der Bereich der hoch bauenden Seitenlangträger für die Abstützung des Stützbocks verwendet.The support bracket is supported with its transverse ends in the area of the side long beams of the railroad car on this or its side long beams. Since piggyback trucks are usually designed with a very low loading area, the arrangement of appropriate guides or brackets for the trestle is difficult in the area of the loading area. In the embodiment according to the present invention, the area of the high-rise side longitudinal members is advantageously used for supporting the support frame.

Die Verriegelung des Stützbocks ist im Bereich dessen Abstützung auf dem Eisenbahnwagen angeordnet. Durch diese Ausbildung wird ebenfalls die Anordnung von zusätzlichen, die Ladeplattform überbauenden Elementen zum Verriegeln des Stützbocks vermieden.The locking of the support frame is arranged in the area of its support on the railroad car. This configuration also avoids the arrangement of additional elements over the loading platform for locking the support frame.

Die Verriegelung des Stützbocks erfolgt nach einem Ausführungsbeispiel der Erfindung mittels je eines vertikal und drehbar an dem Stützbock angeordneten Zapfens, der bei-aufgesetztem Stützbock in Bohrungen der Seitenlangträger des Eisenbahnwagens ragt, wobei der Zapfen an seinem nach unten ragenden Ende einen Exzenter aufweist, der bei verriegeltem Zapfen unter den Seitenlangträger verschwenkt ist. Der Zapfen ist hierbei gemäß einer möglichen Ausführung mittels eines Handgriffs drehbar.According to one embodiment of the invention, the support frame is locked by means of a pin arranged vertically and rotatably on the support frame, which, when the support frame is in place, projects into bores in the side longitudinal members of the railroad car, the pin having an eccentric at its downwardly projecting end, which at locked pin is pivoted under the side member. According to a possible embodiment, the pin can be rotated by means of a handle.

Nach einer weiteren möglichen Ausführung der Erfindung ist der Zapfen über durch eine Feder beaufschlagte Hebel und Schubstangen drehbar, wobei ein erster Hebel, der an einer vertikalen, drehbar am Stützbock gelagerten Welle fest angeordnet ist, mit seinem freien Ende in den Arbeitsbereich der den Stützbock aufnehmenden Zugmaschine ragt, wobei der Hebel durch die aufnehmende Zugmaschine verschwenkt und der Zapfen in Lösestellung verdreht ist und wobei durch die Feder über die Hebel und Schubstange bei abgesetztem Stützbock der Zapfen in Verriegelungsstellung verdreht ist. Durch die Konstruktion nach diesem Ausführungsbeispiel erfolgt die Verriegelung und Lösung des Stützbocks selbsttätig durch die den Stützbock aufnehmende Zugmaschine, ohne weitere manuelle Betätigung.According to a further possible embodiment of the invention, the pin can be rotated via levers and push rods which are acted upon by a spring, a free end of a first lever, which is fixedly arranged on a vertical shaft rotatably mounted on the support frame, in the working area of the support frame Tractor protrudes, wherein the lever is pivoted by the receiving tractor and the pin is rotated in the release position and wherein the pin is rotated in the locking position by the spring via the lever and push rod when the support frame is removed. Due to the construction according to this embodiment, the support frame is locked and released automatically by the tractor receiving the support frame, without further manual actuation.

Der in der Zeichnung dargestellte Stützbock ist in Form eines Portals ausgebildet. Es ist hierbei unerheblich, ob das Portal mit schräg oder vertikal nach unten weisenden Abstützungen ausgebildet ist. Es ist weiter denkbar, daß der Stützbock in Form einer Traverse ausgebildet ist.The support bracket shown in the drawing is designed in the form of a portal. It is irrelevant whether the portal is designed with obliquely or vertically downward supports. It is also conceivable that the support frame is designed in the form of a crossmember.

In dem dargestellten Ausführungsbeispiel besteht der Stützbock aus einer zentralen Tragplatte 1, die beidseitig ihrer Quermitte je zwei schräg nach unten weisende Abstützungen 2 aufweist. An den Abstützungen 2 sind auf deren horizontaler Stützfläche 3 vertikal nach unten weisende Zapfen 4 angeordnet. Die Abstützungen 2 des Stützbocks setzen sich mit ihrer Stützfläche 3 auf entsprechende Abwinklungen 5 der Seitenlangträger 6 des Eisenbahnwagens auf. In den Abwinklungen 5 der Seitenlangträger 6 sind in Abständen Bohrungen zur Aufnahme der Zapfen 4 angeordnet. An den Abstützungen 2 des Stützbocks sind an den zu den Seitenlangträgern weisenden Außenseiten Führungen 7 zum Zentrieren des Stützbocks auf dem Eisenbahnwagen vorgesehen.In the exemplary embodiment shown, the support frame consists of a central support plate 1 which has two supports 2, which point obliquely downwards on both sides of its transverse center. Pins 4 are arranged vertically downward on the supports 2 on their horizontal support surface 3. The supports 2 of the trestle sit with their support surface 3 on corresponding bends 5 of the side long beams 6 of the railroad car. In the bends 5 of the side members 6 holes are arranged at intervals for receiving the pin 4. On the supports 2 of the trestle, guides 7 are provided for centering the trestle on the railway carriage on the outer sides facing the side long beams.

Auf der Oberseite der zentralen Stützplatte 1 des Stützbocks ist eine in Längsrichtung des Stützbocks weisende Sattelkupplung 8 angeordnet. Zentrisch unter der Sattelkupplung 8 ist auf der Unterseite der Tragplatte 1 des Stützbocks ein vertikal nach unten weisender Zugsattelzapfen 9 fest angeordnet. Beidseitig des Zugsattelzapfens ist auf der Unterseite der Sattelplatte 1 mit Abstand je ein Anschlag 10 befestigt, der ein Verdrehen des Stützbocks in aufgesatteltem Zustand verhindert.On the upper side of the central support plate 1 of the support bracket, a fifth wheel 8 is arranged which points in the longitudinal direction of the support bracket. A vertically downward-pointing kingpin 9 is fixedly arranged centrally under the fifth wheel 8 on the underside of the support plate 1 of the support frame. On both sides of the kingpin, a stop 10 is fastened on the underside of the saddle plate 1 at a distance, which prevents the support frame from twisting in the saddled state.

An den Abstützungen 2 des Stützbocks ist jeweils eine Verriegelung für den Stützbock befestigt. In dem in Fig. 2 dargestellten Ausführungsbeispiel besteht diese Verriegelung aus einem vertikal und drehbar angeordneten Zapfen 12, der mit seinem nach unten weisenden Ende in eine Bohrung 13 des Seitenlangträgers 6 ragt. Der Zapfen 12 ist an diesem Ende mit einem Exzenter 14 versehen, der sich in verriegeltem Zustand unter den Seitenlangträger 6 anlegt. Der Zapfen 12 wird durch einen Handgriff 15 an seinem oberen Ende gedreht.A lock for the trestle is attached to the supports 2 of the trestle. In the exemplary embodiment shown in FIG. 2, this locking device consists of a vertically and rotatably arranged pin 12 which, with its end pointing downward, projects into a bore 13 in the side long beam 6. The pin 12 is provided at this end with an eccentric 14, which engages under the side long beam 6 in the locked state. The pin 12 is rotated by a handle 15 at its upper end.

Bei dem in den Fig. und 4 dargestellten Ausführungsbeispiel erfolgt die Verriegelung des Stützbocks ebenfalls über einen vertikal und drehbar an dem Stützbock gelagerten Zapfen 17, an dessen nach unten ragendem Ende ebenfalls ein in den Seitenlangträger 6 ragender Exzenter 18 angeordnet ist. Der Zapfen 17 wird über Hebel 18 und 19, und eine dazwischen geschaltete Zugstange 20, die gelenkig mit den Hebeln 18 und 19 verbunden ist, gedreht. Eine Feder 21 beaufschlagt das Hebelsystem in Schließstellung des Zapfens 17. Der Hebel 19 ist an einer vertikal im Stützbock drehbar gelagerten Welle 22 befestigt, die fest einen weiteren Hebel 23 trägt, der mit seinem freien Ende zur Quermitte des Stützbocks weisend in den Arbeitsbereich der Zugmaschine ragt. Beim Aufsatteln des Stützbocks auf die Zugmaschine verschwenkt diese mit der Tragvorrichtung ihrer Sattelkupplung den Hebel 23 und über diesen die Welle 22, den Hebel 19, die Schubstange 20, den Hebel 18 und den Zapfen 17 in Lösestellung. Der Stützbock kann jetzt mit dem Sattelauflieger auf den Eisenbahnwagen verfahren und auf diesem mit seinen Zapfen 4 in die Seitenlangträger 6 abgesenkt werden. Nach dem Entriegeln der Sattelkupplung der Zugmaschine aus dem Zugsattelzapfen 9 des Stützbocks fährt die Zugmaschine aus dem Stützbock. Hierbei wird das Hebelsystem des Stützbocks durch die Kraft der Feder 21 verschwenkt und der Exzenter 18 des Zapfens 17 in Schließstellung verdreht.In the exemplary embodiment shown in FIGS. 4 and 4, the support frame is also locked via a pin 17 which is mounted vertically and rotatably on the support frame and at the end of which projects downward there is also an eccentric 18 which projects into the side long beam 6. The pin 17 is rotated via levers 18 and 19, and an intermediate connecting rod 20, which is articulated to the levers 18 and 19. A spring 21 acts on the lever system in the closed position of the pin 17. The lever 19 is fastened to a shaft 22 which is rotatably mounted vertically in the support frame and which firmly carries a further lever 23 which points with its free end towards the transverse center of the support frame into the working area of the tractor protrudes. When the support frame is saddled onto the tractor, it swivels the lever 23 with the carrying device of its fifth wheel coupling and, via this, the shaft 22, the lever 19, the push rod 20, the lever 18 and the pin 17 in the release position. The support frame can now be moved with the semi-trailer onto the railroad car and lowered onto the side frame 6 with its pin 4. After unlocking the fifth wheel coupling of the tractor from the kingpin 9 of the trestle, the tractor moves out of the trestle. Here, the lever system of the support bracket is pivoted by the force of the spring 21 and the eccentric 18 of the pin 17 is rotated in the closed position.

Bei dem in Fig. 5 dargestellten Ausführungsbeispiel sind an den Abstützungen 2 des Stützbocks im Bereich seiner Abstützung auf dem Eisenbahnwagen jeweils zwischen zwei Abstützungen je ein zweiarmiger schwenkbarer Hebel 25 gelagert, der an seinem einen in den Seitenlangträger 6 ragenden Ende mit einer Nase 26 versehen ist. Das andere Ende des Hebels 25 ist gelenkig mit einer Schubstange 27 verbunden, deren anderes Ende ebenfalls gelenkig mit einer Kulisse 28 verbunden ist. Die Kulisse 28 ist um eine horizontale Achse senkrecht zur Zeichnungsebene schwenkbar an dem Stützbock gelagert. Die Kulisse 28 ist durch einen Federzylinder 29 beaufschlagt, der mit seinem einen Ende gelenkig an dem Stützbock und mit seinem anderen Ende gelenkig an der Kulisse 28 gelagert ist. Stirnseitig auf ihrem dem Federzylinder 29 entgegengesetzten Ende ist die Kulisse 28 mit einer geschwungenen Führungsfläche 30 versehen. Die Verriegelung wird betätigt durch zwei Schubstangen 31, die rechts und links der Längsachse der Zugmaschine an dieser mittels Hydraulik- oder Pneumatikzylinder betätigt, angeordnet sind. Jeweils eine Schubstange 31 wirkt, von der Zugmaschine aus betätigt, gegen die Führungsfläche 30 der Kulisse 28. Die Kulisse 28 wird hierbei gegen die Kraft des Federzylinders 29 verschwenkt und betätigt über die Schubstange 27 den Hebel 25 in Öffnungs- bzw. Schließstellung. In den Endstellungen wird die Kulisse 28 durch die Kraft des Federzylinders 29 so beaufschlagt, daß keine selbsttätige Entriegelung erfolgen kann.In the embodiment shown in FIG. 5, a two-armed pivotable lever 25 is mounted on the supports 2 of the support frame in the region of its support on the railroad car between two supports, which is provided with a nose 26 on its one end projecting into the side long beam 6 . The other end of the lever 25 is articulated to a push rod 27, the other end of which is also articulated to a link 28. The backdrop 28 is pivotally mounted on the support bracket about a horizontal axis perpendicular to the plane of the drawing. The link 28 is acted upon by a spring cylinder 29 which is articulated at one end on the support frame and at the other end articulated on the link 28. At the end on its end opposite the spring cylinder 29, the link 28 is provided with a curved guide surface 30. The locking is actuated by two push rods 31, which are arranged on the right and left of the longitudinal axis of the tractor and are actuated by means of hydraulic or pneumatic cylinders. Each push rod 31, actuated by the tractor, acts against the guide surface 30 of the link 28. The link 28 is pivoted against the force of the spring cylinder 29 and actuates the lever 25 in the open or closed position via the push rod 27. In the end positions, the link 28 is acted upon by the force of the spring cylinder 29 so that no automatic unlocking can take place.

Bei dem in der Fig. 6 dargestellten Ausführungsbeispiel besteht die Verriegelung ebenfalls aus einem zweiarmigen Hebel 33, der schwenkbar zwischen den Abstützungen 2 des Stützbocks an diesem gelagert ist. Der Hebel 33 ragt mit seinem einen, mit einer Nase 34 versehenen Ende wieder in Ausschnitte des Seitenlangträgers 6. Nahe seinem freien Ende ist an dem Hebel 33 eine Schubstange 35 gelenkig angeordnet, in die ein elastisches Zwischenglied 36 zwischengeschaltet ist. An ihrem zweiten Ende ist die Schubstange 35 gelenkig an dem einen Ende eines zweiarmigen Hebels 37 angeschlossen, der ebenfalls schwenkbar an den Abstützungen 2 des Stützbocks gelagert ist. Das freie Ende des Hebels 37 ist sichelförmig gekrümmt und ragt bei angehobenem Stützbock unter die Abstützflächen 3 des Stützbocks. An den Abstützungen 2 des Stützbocks ist weiter für jeden Hebel 33 eine Sicherungsfalle 38 gegen die Kraft einer Feder 39 schwenkbar angeordnet. Die Sicherungsfalle 38 ist mit einer Nase 40 versehen, die sich in Verriegelungsstellung des Hebels 33 vor dessen nach oben ragendes freies Ende und in Lösestellung des Hebels 33 hinter dessen nach oben ragendes freies Ende legt und den Hebel 33 durch die Kraft der Feder 39 jeweils in einer dieser Endstellungen blockiert. Beim Aufsetzen des Stützbocks auf den Eisenbahnwagen wird der Hebel 37 durch dessen nach unten ragendes freies, sichelförmiges Ende, das sich auf die Abwinklungen 5 der Seitenlangträger 6 des Eisenbahnwagens aufstützt, verschwenkt. Über die Schubstange 35 wird hierbei der Hebel 33, die Sicherungsfalle 38 anhebend, mit verschwenkt und verriegelt über seine Nase 34 den Stützbock auf dem Eisenbahnwagen. Die Nase 40 der Sicherungsfalle 38 blockiert den Hebel 33 in dieser Verriegelungsstellung. Beim Abheben des Stützbocks von dem Eisenbahnwagen wird durch den Hubzylinder der Sattelkupplung der Zugmaschine eine solche Kraft auf den Hebel 33 ausgeübt, daß dieser durch das entstehende Moment gegen die Kraft der Feder 39 die Sicherungsfalle 38 löst und in Lösestellung verschwenkt wird. In dieser Lösestellung wird der Hebel 33 wieder durch die Nase 40 der Sicherungsfalle 38 gehalten. Der Stützbock kann nun vom Eisenbahnwagen abgehoben werden. Schließlich ist es auch denkbar, die Zapfen 4 des Stützbocks elastisch am Stützbock über Gummi- oder Gummimetallelemente zu lagern.In the embodiment shown in Fig. 6, the lock also consists of a two-armed lever 33 which is pivotable between the supports 2 of the support bocks is mounted on this. The lever 33 protrudes with its one end, which is provided with a lug 34, into cutouts in the side long beam 6. Near its free end, a push rod 35 is articulated on the lever 33, into which an elastic intermediate member 36 is interposed. At its second end, the push rod 35 is connected in an articulated manner to one end of a two-armed lever 37, which is also pivotably mounted on the supports 2 of the support frame. The free end of the lever 37 is curved in a crescent shape and, when the support frame is raised, projects under the support surfaces 3 of the support frame. On the supports 2 of the trestle, a safety latch 38 is further arranged pivotably against the force of a spring 39 for each lever 33. The safety latch 38 is provided with a nose 40 which, in the locking position of the lever 33, lies in front of its upwardly projecting free end and in the release position of the lever 33 behind its upwardly projecting free end, and the lever 33 in each case by the force of the spring 39 one of these end positions is blocked. When the trestle is placed on the railroad car, the lever 37 is pivoted by its free, crescent-shaped end which projects downwards and which is supported on the bends 5 of the side longitudinal members 6 of the railroad car. Via the push rod 35, the lever 33, which raises the safety latch 38, is also pivoted and locked via its nose 34 to the support frame on the railroad car. The nose 40 of the safety latch 38 blocks the lever 33 in this locking position. When lifting the trestle from the railroad car, such a force is exerted on the lever 33 by the lifting cylinder of the fifth wheel coupling of the tractor that this releases the safety latch 38 against the force of the spring 39 and is pivoted into the release position. In this release position, the lever 33 is held again by the nose 40 of the safety latch 38. The support frame can now be lifted off the railroad car. Finally, it is also conceivable to mount the pins 4 of the support frame elastically on the support frame via rubber or rubber-metal elements.
