Abstract

On a goods wagon, a loading platform (1) is arranged between two pairs of perpendicular guides (2) facing one another. Two pairs of platform bearings (11) are mounted on the loading platform (1). In each of the guides (2), a guide bolt (7) is guided. With a pair of the platform bearings (11), the loading platform (1) is mounted on a pair of the guide bolts (7) so as to be capable of pivoting about a first horizontal transverse axis. With the other pair of platform bearings (11), the loading platform (1) is mounted on a pair of pendulum supports (13) which can be pivoted on in each case one of the other guide bolts (7) about a second horizontal transverse axis. The loading platform (1) can be moved out of an oblique loading and unloading position into a horizontal transport position, the pendulum support (13) being capable of being moved beyond a dead centre (15) at which they are in a perpendicular position. At the same time, forces which act in the longitudinal direction of the goods wagon and clamp the guide bolts (7) to the guides (2) are produced. As a result, shocks which occur during transport are prevented from causing wear to the guides (2) and noises. <IMAGE>

Description

Die Erfindung betrifft eine Bühnenabstützung für eine höhenverstellbare Ladebühne eines Güterwagens mit Zwei Paar einander zugewandter, seitlich am Güterwagen aufrechtstehend angeordneter Führungen, zwei Paar an der Ladebühne befestigter Bühnenlager und zwei Paar Führungsbolzen, die mit je einem der Bühnenlager verbunden und an je einer der Führungen geführt sind.The invention relates to a stage support for a height-adjustable loading platform of a freight wagon with two pairs of mutually facing guides arranged upright on the side of the freight wagon, two pairs of platform bearings attached to the loading platform and two pairs of guide bolts, each connected to one of the platform bearings and guided on one of the guides are.

Aus der DE-A 25 01 036 ist eine Bühnenabstützung dieser Gattung für die obere Ladebühne eines doppelstöckigen Güterwagens bekannt. Die Bühnenlager sind für die Höhenverstellung der Ladebühne an je einem Seil aufgehängt. In jedem der Bühnenlager ist ein waagerechter, sich längs einer Querachse erstreckender Führungsbolzen längs dieser Querachse verschiebbar gelagert, der mit einem Ende in die zugehörige, seitlich am Güterwagen aufrechtstehend angeordnet Führung eingreift und in der Nähe seines anderen Endes gelenkig mit einem Hebel verbunden ist. Der Hebel ist unterhalb des zugehörigen Führungsbolzens um eine waagerechte Längsachse schwenkbar am Bühnenlager gelagert und oberhalb des Führungsbolzens gelenkig mit einem Bügel verbunden, der bei angehobener Ladebühne in einen an der zugehörigen aufrechtstehenden Führung befestigten Haken einhängbar ist, um das zugehörige Seil zu entlasten. Wenn die Ladebühne auf diese Weise an den Haken aufgehängt ist, übt jeder der Bügel ein Drehmoment auf den zugehörigen Hebel aus und schwenkt diesen nach außen, so daß der mit ihm gelenkig verbundene Lagerbolzen nach außen verschoben und gegen die zugehörige Führung gedrückt wird. Auf diese Weise wird die Ladebühne mit den Führungen verspannt, damit sie beim Fahrbetrieb nicht klappert und möglichst wenig Verschleiß an den Führungen erzeugt. Damit die Ladebühne zum End- oder Beladen abgesenkt werden kann, muß sie an den Seilen nach oben gezogen werden, und dann müssen die Bügel aus den Haken ausgehängt werden, was an jedem einzelnen Bügel von Hand zu geschehen hat.DE-A 25 01 036 discloses a stage support of this type for the upper loading platform of a double-decker freight wagon. The platform bearings are each suspended from a rope for the height adjustment of the loading platform. In each of the stage bearings, a horizontal guide pin extending along a transverse axis is slidably mounted along this transverse axis, which engages with one end in the associated guide arranged upright on the side of the freight wagon and is articulated near its other end with a lever. The lever is pivotally mounted on the stage bearing below the associated guide pin about a horizontal longitudinal axis and is articulated above the guide pin with a bracket that can be hooked into a hook attached to the associated upright guide when the loading platform is raised in order to relieve the associated rope. When the loading platform is suspended from the hook in this way, each of the brackets exerts a torque on the associated lever and pivots it outward, so that the bearing pin articulated with it is displaced outward and pressed against the associated guide. In this way, the loading platform is tensioned with the guides, So that it does not rattle when driving and generates as little wear on the guides as possible. So that the loading platform can be lowered for the end or loading, it must be pulled up on the ropes, and then the brackets must be unhooked, which has to be done by hand on each individual bracket.

Der Erfindung liegt die Aufgabe zugrunde, eine Bühnenabstützung für eine längs aufrechtstehend angeordneter Führungen höhenverstellbare Ladebühne eines Güterwagens zu schaffen, die sich in einer für Fahrbetrieb vorgesehen Stellung selbstätig mit den Führungen verspannt und sich beim Vorbereiten von Ladevorgängen ebenfalls selbstätig aus der Verspannung löst.The invention has for its object to provide a stage support for a longitudinally upright guides height-adjustable loading platform of a freight car, which automatically braces in a position intended for driving operation with the guides and also automatically releases from the tension when preparing loading processes.

Die Aufgabe ist erfindungsgemäß bei einer Bühnenabstützung der eingangs beschriebenen Gattung dadurch gelöst, daß die Ladebühne mit einem Paar Bühnenlager auf den zugehörigen Führungsbolzen um eine erste waagerechte Querachse schwenkbar gelagert ist, mit dem anderen Paar Bühnenlager auf einem Paar Pendelstützen gelagert ist, die auf den zugehörigen Führungsbolzen um eine zweite waagerechte Querachse schwenkbar sind, und die Ladebühne aus einer schrägen Be- und Entladestellung in eine waagerechte Transportstellung bewegbar ist, wobei die Pendelstützen über einen Totpunkt, an dem sie senkrecht stehen, hinwegbewegbar sind.The object is achieved in a stage support of the type described in the introduction in that the loading platform with a pair of stage bearings is pivotally mounted on the associated guide pin about a first horizontal transverse axis, with the other pair of stage bearings is mounted on a pair of pendulum supports which are mounted on the associated Guide bolts are pivotable about a second horizontal transverse axis, and the loading platform can be moved from an oblique loading and unloading position into a horizontal transport position, the pendulum supports being movable away over a dead center at which they are vertical.

Die beiden Pendelstützen der erfindungsgemäßen Bühnenabstützung stehen in der - mindestens annähernd waagerechten - Transportstellung der Ladebühne schräg, so daß das Eigengewicht der Ladebühne sowie deren Nutzlast, beispielsweise Personenkraftwagen, an den Pendelstützen Drehmomente erzeugen. Diese Drehmomente bewirken, daß die Führungsbolzen, auf denen die Pendelstützen gelagert sind, mit einer von deren Schrägstellung und Belastung abhängigen, in Längsrichtung des Güterwagens wirkenden Kraft gegen eine Seitenwand der zugehörigen Führung gepreßt werden. An den beiden übrigen Führungsbolzen entstehen entsprechende Reaktionskräfte mit dem Ergebnis, daß die Ladebühne mit den Bühnenlagern, den Pendelstützen, den Führungsbolzen und den Führungen ein System bilden, das zumindest durch in Längsrichtung des Güterwagens wirkende Kräfte in sich verspannt und somit spielfrei gehalten ist. Durch geeignete Profilgestaltung der Führungen und der in sie eingreifenden Teile der Führungsbolzen läßt sich außerdem erreichen, daß die Ladebühne sich auch in Querrichtung des Güterwagens spielfrei mit den Führungen verspannt.The two pendulum supports of the stage support according to the invention are inclined in the - at least approximately horizontal - transport position of the loading platform, so that the dead weight of the loading platform and its payload, for example passenger cars, generate torques on the pendulum supports. These torques cause the guide pins, on which the pendulum supports are mounted, to be pressed against a side wall of the associated guide with a force which depends on their inclination and load and act in the longitudinal direction of the freight car. Corresponding are created on the two remaining guide bolts Reaction forces with the result that the loading platform with the stage bearings, the pendulum supports, the guide bolts and the guides form a system that is at least tensioned in itself by forces acting in the longitudinal direction of the freight car and is therefore kept free of play. Through a suitable profile design of the guides and the parts of the guide bolts engaging in them, it can also be achieved that the loading platform is also tensioned with the guides in the transverse direction of the freight wagon without play.

Bei einer bevorzugten Ausführungsform der Erfindung haben die Führungen je ein C-förmiges Hohlprofil und die Führungsbolzen weisen je einen dem Hohlraum dieses Profils angepaßten T-förmigen Kopf auf und in den Führungen ist je eine Gewindespindel angeordnet, die sich mit Spiel durch ein Loch im Kopf des zugehörigen Führungsbolzens hindurcherstreckt und diesen über eine Spindelmutter abstützt.In a preferred embodiment of the invention, the guides each have a C-shaped hollow profile and the guide bolts each have a T-shaped head which is adapted to the cavity of this profile, and a threaded spindle is arranged in the guides, which passes through a hole in the head with play of the associated guide pin extends through and supports it via a spindle nut.

Der in Fig. 1 dargestellte Güterwagen hat eine obere Ladebühne 1, die an vier senkrechten Führungen 2 geführt ist. Die Führungen 2 haben gemäß Fig. 5 ein zur Innenseite des Güterwagens hin offenes C-förmiges Profil und sind an je einer Stütze 3 bzw. 4 bzw. 5 bzw. 6 befestigt oder bilden selber je eine solche Stütze. Die Stützen 3 bis 6 sind einander paarweise gegenüberstehend an den Seiten des Güterwagens befestigt.The freight car shown in Fig. 1 has an upper loading platform 1, which is guided on four vertical guides 2. According to FIG. 5, the guides 2 have an inside of the freight car open C-shaped profile and are attached to a support 3 or 4 or 5 or 6 or each form such a support. The supports 3 to 6 are attached in pairs opposite each other on the sides of the freight car.

In den Führungen 2 ist je ein die Ladebühne 1 tragender Führungsbolzen 7 geführt; die Führungsbolzen 7 erstrecken sich waagerecht quer zur Längsrichtung des Güterwagens und sind paarweise miteinander gleichachsig angeordnet. An jedem Führungsbolzen 7 ist ein in Draufsicht T-förmiger Kopf 8 ausgebildet, der den Profilhohlraum der zugehörigen Führung 2 weitgehend ausfüllt und nur ein geringes Spiel in Längs- und Querrichtung freiläßt. Jeder Kopf 8 ruht auf einer Spindelmutter 9, die auf eine in der zugehörigen Führung 2 senkrecht angeordnete Gewindespindel 10 aufgeschraubt ist. Jede der Gewindespindeln 10 erstreckt sich durch ein Langloch im Kopf 8 des zugehörigen Führungsbolzens 7 und ist axial unverschiebbar, jedoch drehbar gelagert. Durch nicht dargestellte Antriebe lassen sich die Gewindespindeln 10 paarweise derart antreiben, daß die Ladebühne 1 schräg gestellt und bei Bedarf als Ganzes gehoben oder gesenkt wird. In Fig. 1 ist die Ladebühne in einer für den Transport geeigneten waagerechten Stellung mit vollen Linien, und in einer für das Be- und Entladen geeigneten Schrägstellung mit strichpunktierten Linien dargestellt.A guide pin 7 carrying the loading platform 1 is guided in the guides 2; the guide bolts 7 extend horizontally across the longitudinal direction of the freight car and are arranged in pairs on the same axis. A top view T-shaped head 8 is formed on each guide pin 7, which largely fills the profile cavity of the associated guide 2 and leaves only a slight play in the longitudinal and transverse directions. Each head 8 rests on a spindle nut 9 which is screwed onto a threaded spindle 10 arranged vertically in the associated guide 2. Each of the threaded spindles 10 extends through an elongated hole in the head 8 of the associated guide pin 7 and is axially immovable, but rotatably mounted. By means of drives, not shown, the threaded spindles 10 can be driven in pairs in such a way that the loading platform 1 is inclined and, if necessary, is raised or lowered as a whole. In Fig. 1, the loading platform is shown in a horizontal position suitable for transport with solid lines, and in an inclined position suitable for loading and unloading with dash-dotted lines.

Die tragende Verbindung zwischen der Ladebühne 1 und den vier Führungsbolzen 7 wird durch vier an der Unterseite der Ladebühne 1 angeordnete Bühnenlager 11 hergestellt. Zwei miteinander fluchtende Führungsbolzen 7 - in Fig. 1 sind es die beiden an den Stützen 3 und 4 angeordneten, sind gemäß Fig. 3 unmittelbar im zugehörigen Bühnenlager 11 gelagert, so daß die Ladebühne 1 um die gemeinsame Achse dieser beiden Führungsbolzen 7 schwenkbar ist. Die beiden übrigen Führungsbolzen 7 sind in je einem Pendelstützenlager 12 gelagert, von dem sich eine Pendelstütze 13 nach oben zum zugehörigen Bühnenlager 11 erstreckt.The load-bearing connection between the loading platform 1 and the four guide bolts 7 is established by four stage bearings 11 arranged on the underside of the loading platform 1. Two aligned guide pins 7 - in Fig. 1 there are the two arranged on the supports 3 and 4, are mounted according to FIG. 3 directly in the associated stage bearing 11, so that the loading platform 1 is pivotable about the common axis of these two guide pins 7. The two remaining guide pins 7 are each mounted in a self-aligning support bearing 12, from which a self-aligning support 13 extends upwards to the associated stage bearing 11.

Die beiden Paare gleichachsig angeordneter Bühnenlager 11 haben, in Längsrichtung des Güterwagens gemessen, einen Abstand voneinander, der größer ist als der Abstand, den die beiden an den Stützsäulen 3 und 4 angeordneten Führungen 2 von den beiden an den Stützsäulen 5 und 6 angeordneten Führungen 2 haben. Infolgedessen stehen die Pendelstützen 13 schräg, wenn die Ladebühne 1 waagerecht angeordnet ist. Dabei ist die gemeinsame Achse der beiden je einer Pendelstütze 13 zugeordneten Bühnenlager 11 um einen Betrag a, der in Fig. 4 dargestellt ist, von der gemeinsamen senkrechten Mittelebene 14 der beiden zugehörigen Führungen 2 entfernt, und somit auch von einem in dieser Mittelebene 14 liegenden oberen Totpunkt 15 der Pendelbewegung. Die Schrägstellung der Pendelstützen 13 hat zur Folge, daß die Köpfe 8 der beiden zugehörigen Führungsbolzen 7 gemäß Fig. 5 nach links gegen eine Seitenwand 16 der zugehörigen Führung 7 gedrückt werden, und daß die Köpfe 8 der beiden übrigen Führungsbolzen 7 in entgegengesetzter Richtung, bezogen auf Fig. 1 also nach rechts, ebenfalls gegen je eine Seitenwand der zugehörigen Führungen 7 gedrückt werden.The two pairs of stage bearings 11 arranged coaxially, measured in the longitudinal direction of the freight wagon, have a distance from one another which is greater than the distance that the two guides 2 arranged on the support columns 3 and 4 have from the two guides 2 arranged on the support columns 5 and 6 to have. As a result, the pendulum supports 13 are inclined when the loading platform 1 is arranged horizontally. The common axis of the two stage bearings 11, each associated with a pendulum support 13, is removed from the common vertical center plane 14 of the two associated guides 2 by an amount a, which is shown in FIG. 4, and thus also from one lying in this center plane 14 top dead center 15 of the pendulum motion. The inclination of the pendulum supports 13 has the result that the heads 8 of the two associated guide pins 7 according to FIG. 5 are pressed to the left against a side wall 16 of the associated guide 7, and that the heads 8 of the two other guide pins 7 refer in the opposite direction 1 to the right, also against one side wall of the associated guides 7.

Um die Ladebühne 1 aus der in Fig. 1 mit durchgehenden Linien gezeichneten Transportstellung in eine Be- und Entladestellung zu bringen, ist es erforderlich, zunächst die beiden in den Stützen 3 und 4 angeordneten Gewindespindeln 10 derart zu drehen, daß das linke Ende der Ladebühne 1 soweit abgesenkt wird, bis die beiden den Stützen 5 und 6 zugeordneten Pendelstützen 13, bezogen auf Fig. 4 entgegen dem Uhrzeugersinn schwenkend, sich durch ihren Totpunkt 15 hindurchbewegt haben und in die in Fig. 4 mit strichpunktierten Linien gezeichnete Stellung gelangt sind. Dann ist es möglich, die Ladebühne 1 als Ganzes ohne nennenswerten Reibungswiderstand der Führungsbolzen 7 in den Führungen 2 weiter abzusenken.In order to bring the loading platform 1 from the transport position drawn with solid lines in FIG. 1 into a loading and unloading position, it is necessary to first turn the two threaded spindles 10 arranged in the supports 3 and 4 such that the left end of the loading platform 1 is lowered until the two pendulum supports 13 assigned to the supports 5 and 6, pivoting counterclockwise with respect to FIG. 4, have moved through their dead center 15 and have reached the position shown in dash-dotted lines in FIG. 4. Then it is possible to further lower the loading platform 1 as a whole in the guides 2 without any significant frictional resistance of the guide bolts 7.

Wenn der Güterwagen nur unten beladen werden soll, beispielsweise mit Kraftfahrzeugen, die so hoch sind, daß sie eine Nutzung der oberen Ladebühne 1 nicht zulassen, ist es möglich, die Ladebühne 1 in eine beliebig höhere als die in Fig. 1 abgebildete Transportstellung zu bringen. Dort verspannt sich die Ladebühne 1 wiederum selbsttätig in den Führungen 2, wenn sie waagerecht gestellt wird. Das Eigengewicht der Ladebühne 1 genügt, um bei der in Fig. 4 mit durchgehenden Linien gezeichneten Schrägstellung der Pendelstützen 13 verschleißträchtige Bewegungen der Ladebühne auch bei den stärksten im Fahrbetrieb vorkommenden Erschütterungen weitgehend zu vermeiden.If the freight wagon is only to be loaded below, for example with motor vehicles which are so high that they do not permit the use of the upper loading platform 1, it is possible to bring the loading platform 1 into any transport position higher than that shown in FIG. 1 . There, the loading platform 1 in turn tensions itself in the guides 2 when it is placed horizontally. The dead weight of the loading platform 1 is sufficient to largely avoid wear-prone movements of the loading platform in the inclined position of the pendulum supports 13 drawn with solid lines in FIG. 4 even with the strongest vibrations occurring during driving operation.
