Description

Die Erfindung bezieht sich auf eine Kombination aus Ausleger und Windengetriebe für Zahnstangenwinden einer Hub- und Absetzvorrichtung für transportable Großbehälter oder dergleichen, wobei die Zahnstangen der Winden an Stützbeinen für den Großbehälter angeordnet und die Ausleger an Anschlußholmen an den Ecken des Großbehälters zu befestigen sind, und die Ausleger ferner, von oben betrachtet, am einen Ende einen U-förmigen Aufnahmeraum zur passenden Aufnahme eines Anschlußholms und am anderen Ende einen U-förmigen Führungsraum für ein Stützbein mit Zahnstange aufweisen.The invention relates to a combination of boom and winch gear for rack winches of a lifting and lowering device for transportable large containers or the like, wherein the toothed racks of the winches are arranged on support legs for the large container and the arms are to be fastened to connecting bars at the corners of the large container, and the brackets further, viewed from above, have at one end a U-shaped receiving space for fittingly receiving a connecting bar and at the other end a U-shaped guide space for a support leg with a rack.

Bei den Großbehältern kann es sich z.B. um Container, Shelter oder Kabinen handeln.The large containers can e.g. are containers, shelters or cabins.

Ein Ausleger der obigen Bauart ist durch das deutsche Gebrauchsmuster 82 35 609 bekannt. Dieser relativ kurze Ausleger besteht aus zwei Platten mit seitlich nach außen offenem, C-förmigem Querschnitt, welche an einem dazwischen angeordneten Distanzstück befestigt sind. An der Außenseite der einen Platte ist das Windengetriebe befestigt, dessen Antriebsritzel in den Führungsraum am einen Ende des Auslegers hineinragt und mit der Zahnstange am Stützbein in Eingriff steht. Durch das fest angebaute Windengetriebe hat dieser Ausleger ein relativ hohes Gewicht, welches sich bei größeren Ausleger-Längen, wie sie beispielsweise bei der Verladung von Großbehältern in Transportflugzeugen benötigt werden, unakzeptabel erhöhen würde. Es ist hervorzuheben, daß nach Gebrauch der Hub- und Absetzvorrichtung dieselbe in Ersatzteile mit relativ geringem Stückgewicht zerlegbar sein soll, damit diese Teile relativ leicht getragen und verstaut werden können.A boom of the above type is known from German utility model 82 35 609. This relatively short boom consists of two plates with a C-shaped cross-section open to the outside, which are attached to a spacer arranged between them. The winch gear is fastened to the outside of one plate, the drive pinion of which projects into the guide space at one end of the boom and is in engagement with the toothed rack on the support leg. Due to the permanently attached winch gear, this boom has a relatively high weight, which would increase unacceptably with longer boom lengths, such as are required, for example, when loading large containers in transport aircraft. It should be emphasized that after use of the lifting and setting down device it should be possible to dismantle it into spare parts with a relatively low unit weight, so that these parts can be carried and stowed relatively easily.

Durch die DE-PS 3 224 890 ist ferner eine Hub- bzw. Absetzvorrichtung für transportable Großbehälter bekannt, bei welcher Ausleger verwendet werden, an welchen die Windengetriebe mittels Steckbolzen lösbar befestigt sind, so daß sie nach Beendigung des Einsatzes der Hub- und Absetzvorrichtung von den Auslegern entfernt werden können. Die Ausleger dieser bekannten Vorrichtung sind jedoch nicht zur Befestigung an behälterseitigen Anschlußholmen geeignet.From DE-PS 3 224 890 a lifting or lowering device for transportable large containers is also known, in which cantilevers are used, to which the winch gear is detachably fastened by means of plug bolts, so that after the use of the lifting and lowering device has ended the jibs can be removed. However, the arms of this known device are not suitable for attachment to connecting bars on the container side.

Der Erfindung liegt die Aufgabe zugrunde, einen Ausleger der eingangs bezeichneten Bauart derart weiterzubilden, daß er auch bei relativ größerer Länge ein verhältnismäßig geringes Gewicht besitzt und daher leicht zu manipulieren ist.The invention has for its object to develop a boom of the type mentioned in such a way that it has a relatively low weight even with a relatively long length and is therefore easy to manipulate.

Gemäß der Erfindung wird obige Aufgabe dadurch gelöst,

  • a) daß der U-förmige Aufnahmeraum und der U-förmige Führungsraum als gabelförmige Anschlußteile des einstückigen Auslegers ausgebildet sind, die über ein Mittelteil verbunden sind, wobei das eine Anschlußteil gegen die Mitte des Mittelteils sich verjüngt und von dort in gleichmäßiger Breite in das andere gabelförmige Anschlußteil verläuft,
  • b) daß in einem Teil des als Führungsraum ausgebildeten gabelförmigen Anschlußteils das Gehäuse des Windengetriebes lösbar so eingebaut ist, daß der Führungsraum durch das Gehäuse des Windengetriebes nach außen abgeschlossen ist und die größte Bauhöhe des Auslegers etwa der Bauhöhe des Gehäuses des Windengetriebes entspricht und
  • c) daß ferner die größte Bauhöhe des Auslegers an seinem Befestigungsende gegenüber dem Anschlußholm
    Figure imgb0001
    ist, wobei X für die Länge des Auslegers von seinem Befestigungsende bis zur Innenseite des Führungsraums in seinem gabelförmigen Anschlußteil steht.
According to the invention, the above object is achieved by
  • a) that the U-shaped receiving space and the U-shaped guide space are designed as fork-shaped connecting parts of the one-piece boom, which are connected via a central part, the one connecting part tapering towards the center of the central part and from there in a uniform width into the other fork-shaped connecting part runs,
  • b) that in a part of the fork-shaped connecting part designed as a guide space, the housing of the winch gear is detachably installed such that the guide space is closed to the outside by the housing of the winch gear and the greatest height of the boom corresponds approximately to the height of the housing of the winch gear and
  • c) that also the greatest height of the boom at its fastening end opposite the connecting rod
    Figure imgb0001
     is, X stands for the length of the boom from its fastening end to the inside of the guide space in its fork-shaped connecting part.

Bedingt durch die spezielle Form hat dieser Ausleger ein relativ schmales gewichtsparendes Mittelteil mit gabelförmigen Anschlußteilen an seinen Enden und in Verbindung mit der Flachbauweise wird nach Entfernung des Windengetriebes ein zur Manipulation akzeptables Stückgewicht erzielt. Von Bedeutung ist ferner, daß der Ausleger praktisch ohne Einbuße der obigen Vorteile auch in einer größeren Länge hergestellt werden kann, wie sie bei der Verladung von Großbehältern in Transportflugzeugen benötigt wird.Due to the special shape, this boom has a relatively narrow, weight-saving central part with fork-shaped connecting parts at its ends and, in conjunction with the flat design, a piece weight that is acceptable for manipulation is achieved after removal of the winch gear. It is also important that the boom can be manufactured practically without losing the above advantages in a longer length, as is required when loading large containers in transport aircraft.

Eine weitere Ausgestaltung der Erfindung, welche die Einsatzmöglichkeiten des Auslegers und damit der gesamten Vorrichtung vergrößert, ist dadurch gekennzeichnet, daß der Aufnahmeraum und der Führungsraum, von oben betrachtet, im rechten Winkel angeordnet sind.Another embodiment of the invention, which increases the possible uses of the boom and thus the entire device, is characterized in that the receiving space and the guide space, viewed from above, are arranged at right angles.

Die Erfindung wird anschließend anhand der Zeichnungen von Ausführungsbeispielen erläutert. Es zeigen:

  • Fig. 1 eine Stirnansicht von einem Teil eines angehobenen Großbehälters mit einem an einer Ecke desselben befestigten Anschlußholm, an dem ein Ausleger für eine Zahnstangenwinde angeschlossen ist, deren Stützbein auf dem Boden aufgestellt ist, wobei in strichpunktierten Linien ein Rumpfteil im Bereich der Ladeöffnung eines Transportflugzeugs sowie eine Laderampe angedeutet sind;
  • Fig. 2 eine Draufsicht des in Fig. 1 gezeigten Auslegers im vergrößerten Maßstab und
  • Fig. 3 eine weitere Draufsicht einer anderen Ausführungsform des Auslegers gemäß der Erfindung.
The invention is subsequently explained with reference to the drawings of exemplary embodiments. Show it:
  • Fig. 1 is a front view of part of a raised large container with a corner bracket attached to the same, to which a boom for a rack and pinion winch is connected, the support leg of which is set up on the ground, with a fuselage part in the area of the loading opening of a transport aircraft in dash-dotted lines as well as a loading ramp are indicated;
  • Fig. 2 is a plan view of the boom shown in Fig. 1 on an enlarged scale and
  • Fig. 3 is another plan view of another embodiment of the boom according to the invention.

Der anzuhebende bzw. abzusetzende oder auch im Abstand vom Boden abzustützende Großbehälter 10 hat einen rechteckigen Grundriß und weist an seinen vier Ecken oben und unten genormte Eckbeschläge 11 auf. an welchen jeweils ein Anschlußholm 12 lösbar befestigt ist. Die Anschlußholme 12 bestehen aus Rohren mit beispielsweise quadratischem Querschnitt (vergl. Figuren 2 und 3). Auch ein rechteckiger, runder oder polygoner, z.B. 6-eckiger Querschnitt ist möglich.The large container 10 to be lifted or set down or also to be supported at a distance from the floor has a rectangular outline and has standard corner fittings 11 at its four corners at the top and bottom. to which a connecting bar 12 is releasably attached. The connecting bars 12 consist of tubes with, for example, a square cross section (see FIGS. 2 and 3). A rectangular, round or polygonal one, e.g. Hexagonal cross-section is possible.

Die Hub- und Absetzvorrichtung für den Großbehälter 10 weist im einzelnen vier Zahnstangenwinden 13 auf, die über Ausleger 14 mit den Anschlußholmen 12 lösbar verbunden werden können. Jeder Ausleger 14 besteht beispielsweise aus einem Gußteil in der Form eines überdimensionalen Schraubenschlüssels. Die Ausleger 14 weisen, von oben betrachtet, ein gabelförmiges Anschlußteil 15 mit einem U-förmigen Aufnahmeraum 16 auf, mit dem der Ausleger 14 auf einen Anschlußholm 12 passend aufgesteckt und mittels zweier Steckbolzen 17 an dem Holm lösbar fixiert werden kann. Die Steckbolzen 17 erstrecken sich durch entsprechende Bohrungen im Holm 12 sowie in dem gabelförmigen Anschlußteil 15. Das gabelförmige Anschlußteil 15 verjüngt sich gegen die Mitte und geht in ein relativ schmales Mittelteil 18 über, welches an seinem äußeren Ende ein weiteres gabelförmiges Teil 19 mit einem U-förmigen Führungsraum 20 für ein Stützbein 21 trägt. An der Außenseite jedes Stützbeins 21 ist achsparallel eine Zahnstange 22 befestigt, die in ein Antriebsritzel (nicht gezeigt) eines Windengetriebes 23 eingreift das durch eine Handkurbel 24 betätigbar ist. Das Gehäuse des Windengetriebes 23 ist mitiels zweier Steckbolzen 25 lösbar in einen Teil des U-förmigen Führungsraums 20 eingebaut und schließt diesen nach außen ab, wodurch das aus einem Vierkantrohr bestehende Stützbein 21 allseitig geführt ist. Die Steckbolzen 25 erstrecken sich durch nichtgezeigte Bohrungen im gabelförmigen Teil 19 und im Getriebegehäuse.The lifting and depositing device for the large container 10 has four rack winches 13 in particular, which can be detachably connected to the connecting bars 12 by means of brackets 14. Each boom 14 consists, for example, of a cast part in the form of an oversized screw key. The arms 14, viewed from above, have a fork-shaped connecting part 15 with a U-shaped receiving space 16, with which the arm 14 can be fitted onto a connecting bar 12 and can be detachably fixed to the spar by means of two plug bolts 17. The socket bolts 17 extend through corresponding bores in the spar 12 and in the fork-shaped connecting part 15. The fork-shaped connecting part 15 tapers towards the center and merges into a relatively narrow middle part 18, which has a further fork-shaped part 19 with a U at its outer end -shaped guide space 20 for a support leg 21 carries. On the outside of each support leg 21, a toothed rack 22 is secured axially parallel, which engages in a drive pinion (not shown) of a winch gear 23 which can be actuated by a hand crank 24. The housing of the winch gear 23 is releasably installed in two parts of the U-shaped guide space 20 by means of two socket pins 25 and closes it off from the outside, as a result of which the support leg 21 consisting of a square tube is guided on all sides. The socket pins 25 extend through bores, not shown, in the fork-shaped part 19 and in the gear housing.

Der in Fig. 3 in der Draufsicht gezeigte Ausleger 14' entspricht im wesentlichen demjenigen nach den Figuren 1 und 2 mit der Ausnahme, daß das gabelförmige Teil 19' mit seinem Führungsraum 20' für ein Stützbein 21 im rechten Winkel zum gabelförmigen Teil 15 bzw. den Aufnahmeraum 16 angeordnet ist. Dadurch können mittels einer nicht gezeigten Welle z.B. gegenüber einer Schmalseite des Großbehälters 10 zwei Windengetriebe 23 antriebsmäßig so verbunden werden, daß zu ihrer Betätigung nur eine Handkurbel 24 gedreht werden muß.The boom 14 'shown in plan view in FIG. 3 corresponds essentially to that according to FIGS. 1 and 2 with the exception that the fork-shaped part 19' with its guide space 20 'for a support leg 21 at right angles to the fork-shaped part 15 or the receiving space 16 is arranged. As a result, e.g. Compared to a narrow side of the large container 10, two winch gears 23 are connected in terms of drive in such a way that only one hand crank 24 has to be turned to actuate them.

Von Bedeutung ist ferner, daß die Ausleger 14 oder 14' sehr flachbauend ausgebildet sind, wobei im Ausführungsbeispiel nach Fig. 1 ihre größte Höhe Y am gabelförmigen Anschlußteil 15 die Bauhöhe H des Gehäuses des Windengetriebes 23 nur geringfügig überschreitet. Bei den Ausführungsbeispielen nach den Figuren 1 bis 3 ist ferner die größte Bauhöhe Y des Auslegers 14 bzw. 14': Y:5 0,8 • X. Darin bedeutet X die Länge des Auslegers 14 oder 14' von seinem Befestigungsende bis zu einer Innenseite 26 bzw. 26' des U-förmigen Führungsraums 20 bzw. 20'. Aufgrund dieser Flachbauweise sind die Ausleger 14 bzw. 14' speziell für Hub- und Absetzvorrichtungen geeignet, die zum Verladen von Großbehältern 10 in Transportflugzeugen verwendet werden. Hier steht nämlich im Bereich der heckseitigen Ladeöffnung dieser Flugzeuge nur ein Zwischenraum begrenzter Höhe zwischen einer Laderampe 27 und Teilen 28 des Flugzeugrumpfes zur Aufnahme der Ausleger 14 zur Verfügung, wie in Fig. 1 angedeutet ist.It is also important that the arms 14 or 14 'are of a very flat construction, with their greatest height Y at the fork-shaped connecting part 15 in the exemplary embodiment according to FIG. 1 only slightly exceeding the overall height H of the housing of the winch gear 23. In the exemplary embodiments according to FIGS. 1 to 3, the greatest overall height Y of the bracket 14 or 14 'is: Y: 5 0.8 • X. In this, X means the length of the bracket 14 or 14' from its fastening end to an inside 26 or 26 'of the U-shaped guide space 20 or 20'. Because of this flat construction, the booms 14 and 14 'are particularly suitable for lifting and depositing devices which are used for loading large containers 10 in transport aircraft. Here, in the area of the rear loading opening of these aircraft, there is only a space of limited height between a loading ramp 27 and parts 28 of the fuselage for receiving the boom 14, as indicated in FIG. 1.

Die vorstehend im einzelnen beschriebenen Ausleger 14 oder 14' werden mit ihren Windengetrieben 23 in gleicher Ausbildung an den vier, den Ecken des Großbehälters 10 zugeordneten Anschlußholmen 12 angebaut. Zwei einander gegenüberliegende Windengetriebe 23 werden jeweils vorzugsweise durch eine Welle antriebsmäßig verbunden, so daß zum Heben oder Senken des Großbehälters 10 nur zwei Handkurbeln 24 synchron gedreht werden müssen. Dabei wandern, je nach Drehrichtung der Handkurbeln 24 die Ausleger 14 oder 14' entlang den Stützbeinen 21 auf oder ab, wodurch der Großbehälter 10 entsprechend gehoben bzw. gesenkt werden kann.The brackets 14 or 14 'described in detail above are mounted with their winch gears 23 in the same configuration on the four connecting bars 12 assigned to the corners of the large container 10. Two opposite winch gears 23 are each preferably connected by a shaft, so that only two hand cranks 24 need to be rotated synchronously to raise or lower the large container 10. Depending on the direction of rotation of the hand cranks 24, the arms 14 or 14 'move up or down along the support legs 21, as a result of which the large container 10 can be raised or lowered accordingly.

Es ist aber auch möglich, einen Großbehälter 1-0 in angehobenem Zustand über die Ausleger 14 bzw. 14' auf den Stützbeinen 21 abzustützen.However, it is also possible to support a large container 1-0 in the raised state via the arms 14 or 14 'on the support legs 21.
