Definitions
- the invention relates to a loading device in order to be able to reload swap containers, be it with standardized or non-standardized external dimensions, which, however, as a rule have standardized corner fastenings, and be transported by trucks, with the simplest possible aids.
- the reloading concerns in particular the removal from the truck and bringing it into the hold e.g. of a cargo plane over an inclined loading ramp.
- each corner unit comprises a support foot, the upper end of which is connected to the container corner via a spacer and a fastening rod and the extendable lower end of which comprises a wheel unit.
- the upper and lower ends of the support leg are shifted against each other by means of a crank handle and rack, whereby the crank handle must necessarily be arranged on the upper part of the support bracket connected to the container at the same height.
- US-A-3986702 shows a device for jacking up a container, such as a mobile home, which has no wheels on the individual corner units, in which two of the corner units are always actuated together with a valve block, and one of the coupled units has the functions "lifting” and "lowering” on the valve block, each differentiated according to the individual coupling options.
- the oil tank and the hydraulic hand pump are located together in or on the same component, for example the spacer or the wheel unit, so that when the corner unit is disassembled into its individual components, the pump and the Oil containers do not have to be separated from one another, and there is no risk of entry of false air into the system.
- the oil containers and the hydraulic pump are preferably accommodated in the spacer between the fastening rod and the support foot, where on the one hand there is sufficient installation space and on the other hand the risk of damage is low, since this spacer is enclosed by the two adjacent assemblies and is therefore well supported. Another possibility would be the accommodation on the wheel unit, which, however, assumes a more exposed position during travel and can be damaged more easily.
- One problem to be solved is to lift the container evenly, i.e. without any skew, despite any unevenness in the floor.
- the containers can first be brought into a horizontal position by individually lifting the individual corner units, and then the containers can be pumped up evenly by connecting the corner units connected to one another in parallel.
- the position of the hand pump changes with the height of the container.
- the hand pump When delivered by truck, the hand pump is located above the bottom surface of the container, and thus clearly above head height, approximately at a height of 2.30 m.
- the ratchet used according to the invention which drives the hydraulic hand pump, which is usually designed as an axial piston point, on the other hand, for example, has a hexagon on which a correspondingly long crossbar can be placed as an actuating lever and can be actuated by the operator as a lever arm.
- this crossbar is either braced directly downwards or horizontally braced, and can therefore be operated by the operator with full force regardless of the height of the container and thus the hydraulic pump.
- the two corner units attached along a longitudinal side of the container are each hydraulically connected to one another, it is sufficient if only one of the two corner units coupled to one another has a hand pump and a valve block for setting the hydraulic function.
- the valve block then comes out with six switch positions, in which two times five connections are to be connected to each other.
- the preferred embodiment consists in the hydraulic coupling of two corner units, as this reduces the construction effort.
- the thickness of the spacer should not be greater than the thickness of the fastening rod or of the extendable support foot. For reasons of stability, this is approximately 20 cm.
- valve block should be able to be adjusted on the easily accessible front broad side of the spacer.
- the valve block is designed as a pivotable shaft that extends through the maximum 20 cm depth of the spacer and is coupled to a sufficiently large, clear dial on the front of the spacer, and with two corner units that can be coupled together, a total of six switch positions, namely control of one corner unit separately, control of the other corner unit separately, control of the two coupled corner units together, and this each differentiated for lifting and lowering.
- the support leg is preferably formed with three segments which can be pushed into one another, with not a single large but parallel two small hydraulic cylinders, of which the is located in the middle segment one can shift the first and the other the last of the three merging segments with respect to the middle segment.
- each corner unit is plugged into one another via positive connections and secured by means of push-through bolts, so that the entire corner unit can be assembled from the assemblies one after the other by two men, if necessary only by one, the individual assemblies having a weight that is still one single man can be handled.
- the fastening rods are therefore arranged from the long sides on the upper and lower corner locks parallel to the vertical outer edges of the container, in which the suspension head is first locked in the correct position on the fastening rod in accordance with the dimensions of the container, and then the suspension head with its from hanging bolts protruding downwards from above into the hole in the upper corner lock. Then the lower end of the fastening rod is located parallel outside in the system on the lower corner lock, so that a toggle can be rotated and tightened in a known manner within the elongated hole of the corner lock by means of a handwheel, so that the fastening rod is form-fitting is connected to the container and can absorb sufficient forces to lift the container.
- a support trapezoid is first attached to the separate wheel unit, which consists of a turntable with double rollers arranged underneath with a caster, which has small support rollers at its most widely spaced ends and located deep above the ground.
- the inclination of the support trapezoid relative to the wheel unit can be adjusted by at least one adjusting screw and the turntable of the wheel unit can thus be adjusted horizontally.
- a correspondingly shaped insertion block which is located at the lower end of the support foot, is inserted into a guide shoe on the top of the turntable of the wheel unit, which is only open on one side, and a fixed connection between the support foot and the wheel unit is made by means of push-through bolts .
- the wheel unit must be leveled beforehand using the trapezoid so that the entire unit does not tip over when the support leg is attached.
- the entire spacer is now attached to the support leg by means of two push-through bolts and connected to the hydraulic cylinders located in the interior of the support leg by means of hydraulic quick couplings.
- the support foot and thus the spacer is extended by the operator to such a height by means of the hand pump that the spacer is at the height of the corresponding fastening tabs of the fastening rod fastened to the container.
- the wheel unit is moved with the raised support foot against the fastening rod and secured by means of vertically guided push-through bolts, with the spacer and the support foot generally transverse to the longitudinal axis of the Containers, so at right angles to the lateral outer surface of the container, is moved and protrudes at right angles from this, so that the individual wheel units of the four corner units in the transverse direction of the container have a maximum support distance from each other.
- the container is additionally raised in order to get out of contact with the truck chassis and to pull the truck out from under the container.
- the container is then lowered to just above the ground, on the one hand to achieve a low center of gravity and, on the other hand, to allow it to be moved and brought into the aircraft.
- it is necessary to compensate for uneven floors by extending or retracting individual corner units or pairs of corner units.
- the spacers around the push-through bolts which represent the connection to the fastening rod, must also be pivoted to such an extent that the support foot and the wheel unit are located within the outer edges of the fastening rod arranged in a stationary manner on the container. This is necessary because, on the one hand, there is not enough space inside the aircraft outside of the container, and on the other hand there are predetermined load paths within the ramp into the aircraft, the spacing of which must be set to the distances between the wheel units.
- the container can be ramped into the aircraft either by means of a winch be pulled in or pushed in by means of a vehicle.
- the container is steered with the help of a handlebar, which is attached to each of the four wheel units and can be guided manually by an operator, whereby either steering of the front wheel units in the direction of travel is possible (the two wheel units at the front in the direction of travel can also be connected by means of a visual connection Tie rod are steered in parallel), or the corner units that are reversed in the direction of travel are deflected out of the gear alignment, which they normally take due to the caster that is present in all wheel units.
- FIG. 1 shows a container equipped with four corner units (1) and a drawbar (33) and two longitudinal bars (32) and a wishbone (30).
- the two corner units (1) in the upper half of the figure are not hydraulically operatively connected to one another, while the two corner units (1) in the lower half of the figure are connected to one another via hydraulic lines (7).
- the right corner unit (1) in the lower half of the figure is still equipped with the trapezoid (20) and thus the support wheels (21), and is in the extended position, the wheel unit (4) of this corner unit being in the most wise of the lateral outer surface of the container distant position, ie striving at about 90 ° from it, is located at the level of the front edge of the container.
- the other three corner units (1) are already in the folded position, in which the wheel units (4) are located within the outer edges of the fastening rods (2), which are used for moving the container into the narrow aircraft.
- the spacers (5) are fixed relative to the fastening rods (2) by inserted adjusting bolts (37), which pass through then aligned bores (38) of the spacer (5) and the fastening lugs (23 ') of the fastening rods (2) extend.
- the spacers (5) and thus the wheel units (4) protrude vertically from the longitudinal outer walls of the container, as in the lower right corner unit of Figure 1 to offer the largest possible support width during the process.
- the container is moved by means of a drawbar (33) which can be attached to the lower ends of the fastening rods (2), namely eyes (36) attached there, and can be pulled by any towing vehicle.
- a drawbar (33) which can be attached to the lower ends of the fastening rods (2), namely eyes (36) attached there, and can be pulled by any towing vehicle.

- Each fastening rod (2) rests with an upper plate (34) on the top of the container, a better e.g.
- the hanging pin (35) shown in FIG. 4 extends downward into the opening of the corner fitting (40) of the container.
- the fastening rods (2) run close to the vertical outer edges of the container downwards, with the fastening lugs (23 ') striving to arrange the spacers (5) with the support feet (3) over the fastening rod (2) .
- the wheel units (4) can be folded in so far that they are located approximately at the same distance as the corner fittings (40) from the longitudinal central axis of the container, i.e. within the outer edges of the mounting rods (2), and thus within the envelope profile of the receiving aircraft, as shown in Figure 4.
- the wheel units (4) lifted off the ground can be folded inwards to such an extent that the spacers (5) lie approximately parallel to the front and rear end faces of the containers.
- FIGS. 2a to 2c show the steps of assembling a corner unit in order to attach it to the corner of, for example, a high-lying container on a truck, as shown in FIG. 3.
- a turntable (17) is arranged on the wheel unit (4), which consists of a guide shoe (18), under which and rotatable about an essentially perpendicular axis relative to the guide shoe (18)
- Two wheels (16), preferably with full rubber tires, are mounted parallel to one another, specifically outside the vertical axis of rotation (47) between the guide shoe (18) and the turntable (17), that is to say with caster.
- bolts (31 ') or brackets (31) projecting from the turntable (17) are arranged so as to lift off a wishbone (30) on the bolts (31'). plug on, or on the tabs (31) a handlebar (32).
- a support wheel trapezoid (20) about an axis (42) is arranged on the turntable (17), the struts of the support wheel trapezoid (20) projecting substantially obliquely downwards against the ground, and on them low-lying ends have support wheels (21).
- the inclination of the turntable (17) and thus the entire wheel unit (4) can be adjusted by adjusting an adjusting screw (41) and thus the relative position between the trapezoidal trapezoidal wheel (20) and the turntable (17).
- FIG. 2b shows, after the turntable (17) has been placed horizontally, an insertion block (19) which fits into the guide shoe (18) of the turntable (17) and is located at the lower, extendable end of the support foot (3), one of which open side inserted into the guide shoe (18) and secured there by means of push-through bolts (22).
- each fastening tab (23) On the upper part (43) of the support foot (3) two fastening tabs (23) are arranged at a defined distance from each other, which strive in the same direction on the one hand and have through-bores in order to fasten the spacer (5) to it by means of push-through bolts (22), as shown in Figure 2c. Furthermore, each fastening tab (23) an approximately circular ring around the support point (3) at a distance from the handle bar (24), which serves to guide the support foot (3).
- the spacer (5) already attached to the support foot (3) in FIG. 2c essentially consists of profiles (25) which run transversely at the top and bottom, and a housing (26) arranged between them, in which the oil container (9) and the one Hydraulic hand pump (8) with the ratchet (11) driving it.
- the hydraulic lines (7) of the spacer (5) can be connected to the hydraulic lines (7) of the support foot (3) via quick-release couplings (44).
- control shaft (13) with the externally visible and rotatable dial (14), which enables the individual valve circuits, is arranged in the housing (26).
- the fastening rod (2) must be connected to the rest of the corner unit (1) that has already been installed.
- Either the mounting rod (2) can be attached to the container beforehand by - after adjusting the mounting head (27) at the correct height on the mounting rod (2) using push-through bolts (22) - the mounting pin (35) of the mounting rod (2) from above into the corresponding opening of the corner fitting (40) of the container.
- the top plate (34) rests on the top of the container and extends obliquely downwards over the center piece (28) of the hanging head (27) to the fastening rod (2), which is at a distance from the outside of the container, around the latter To avoid damage.
- the rest of the corner unit (1) can then be brought to the height of the fastening rod (2) by extending the support foot (3), moved up to it and connected to it.
- the usual procedure is to fasten the fastening rod (2) to the free ends of the spacer (5) without prior connection to the container, this time by means of vertically guided push-through bolts (22) that pass through the fastening lugs (23 ') of the fastening rod as well as aligned holes in the profiles (25) of the spacer (5).
- the rotational position of the spacer relative to these fastening tabs (23 ') is determined by adjusting bolts (37) which can engage in different bores in the fastening tabs (23') and are guided in guide sleeves of the profiles (5) by means of a helical link (48), to enable it to snap into and out of the bores (38).
- the unit is then raised to the height corresponding to the container, and the previously described hanging and fastening of the fastening rod (2) to the container, as in FIG. 3, for one the loading area of a truck delivered container.

It can be seen that the entire wheel unit (4) is inside the outer edge of the fastening rod (2), and the support foot (3) is even inside the outer edges of the container.
- the sloping center piece (28) runs from the upper end of the fastening rod (2) to the upper plate (34) of the hanging head (27) which rises directly and only approx. 1 cm above the upper edge of the container.
- FIG. 5 shows a partial sectional view of a support foot (3), in which the upper part (43) represents the first segment (3a) of three segments (3a to 3c) which can be moved into one another, the lowest segment (3c) with the wheel unit (4) connected is.
- the necessary lifting force for the container by no means requires a hydraulic cylinder that corresponds to the external dimensions of the support leg (3), which is large for stability reasons.
- two hydraulic cylinders (6a and 6b), which can eject their hydraulic pistons (15a and 15b) in opposite directions, are arranged in parallel within the middle segment (3b), and these hydraulic pistons (15a and 15b) with the upper segment (3a), that is, the upper part (43), on the one hand, and the lower segment (3c), on the other hand, are connected.
- the individual hydraulic cylinders (6a and 6b) have a diameter of only about 4 cm, which drastically reduces the amount of oil required.
- the oil tank (9) and the hydraulic hand pump (8) are also housed in the upper part of the wheel unit (4) which does not rotate with the turntable (17) with respect to the support leg (3), so that there is the possibility of wheel unit (4 ) and support leg (3) together on the mounting rod (2), so that you do not have to separate the quick couplings between the pump and oil tank on the one hand and the hydraulic pistons on the other.

Description
Die Erfindung betrifft ein Verladegerät, um Wechsel-Container, sei es mit genormten oder ungenormten Außenabmessungen, die in der Regel jedoch genormte Eckbefestigungen aufweisen, und von LKWs transportiert werden, mit möglichst einfachen Hilfsmitteln umladen zu können. Das Umladen betrifft dabei insbesondere das Abnehmen vom LKW und Verbringen in den Laderaum z.B. eines Frachtflugzeuges über eine schräge Laderampe.The invention relates to a loading device in order to be able to reload swap containers, be it with standardized or non-standardized external dimensions, which, however, as a rule have standardized corner fastenings, and be transported by trucks, with the simplest possible aids. The reloading concerns in particular the removal from the truck and bringing it into the hold e.g. of a cargo plane over an inclined loading ramp.
Dies bereitet insbesondere bei kranbaren Containern, die über keine eigenen, ausfahrbaren Stützfüße zum Abstützen oberhalb des LKW verfügen, Probleme, da dann umfangreiche Hilfsgeräte, beispielsweise ein ausreichend großer und schwerer Gabelstapler, vorhanden sein müßten.This creates problems, in particular with craneable containers which do not have their own extendable support feet for support above the truck, since extensive auxiliary devices, for example a sufficiently large and heavy forklift truck, would then have to be present.
Gerade beim Entladen von Frachtflugzeugen an untypischen Stellen, also keinen regulären Flughäfen, werden derartige umfangreiche Hilfsgeräte jedoch nicht vorhanden sein.However, such extensive auxiliary devices will not be available, especially when unloading cargo planes at unusual locations, i.e. not regular airports.
Zu diesem Zweck ist es aus der FR-A-2369202 bereits bekannt, ein Verladegerät, bestehend aus vier Eckeinheiten, einzusetzen, wobei jede Eckeinheit an einer Ecke des Containers befestigt wird, und mittels Handpumpe und Hydraulikzylinder die entsprechende Ecke des Containers in die Höhe bewegt bzw. absenkt werden kann. Zu diesem Zweck umfaßt jede Eckeinheit einen Stützfuß, dessen oberes Ende über einen Abstandshalter und eine Befestigungsstange mit der Container-Ecke verbunden ist und dessen ausfahrbares unteres Ende eine Radeinheit umfaßt. Oberes und unteres Ende des Stützfußes werden gegeneinander mittels Handkurbel und Zahnstange verschoben, wobei notgedrungenermaßen die Handkurbel am oberen, mit dem Container höhengleich verbundenen, Teil des Stützfußes angeordnet sein muß.For this purpose, it is already known from FR-A-2369202 to use a loading device consisting of four corner units, each corner unit being fastened to a corner of the container, and the corresponding corner of the container being lifted by means of a hand pump and hydraulic cylinder or can be lowered. For this purpose, each corner unit comprises a support foot, the upper end of which is connected to the container corner via a spacer and a fastening rod and the extendable lower end of which comprises a wheel unit. The upper and lower ends of the support leg are shifted against each other by means of a crank handle and rack, whereby the crank handle must necessarily be arranged on the upper part of the support bracket connected to the container at the same height.
Darüber hinaus zeigt die US-A-3986702 ein Gerät zum Aufbocken eines Containers wie etwa eines Mobilhomes, welches zwar an den einzelnen Eckeinheiten keine Räder aufweist, bei dem je zwei der Eckeinheiten immer zusammen mit einem Ventilblock betätigt werden, und eine der Miteinander gekoppelten Einheiten am Ventilblock die Funktionen "Heben" und "Senken", jeweils unterschieden nach den einzelnen Kopplungsmöglichkeiten, aufweist.Furthermore, US-A-3986702 shows a device for jacking up a container, such as a mobile home, which has no wheels on the individual corner units, in which two of the corner units are always actuated together with a valve block, and one of the coupled units has the functions "lifting" and "lowering" on the valve block, each differentiated according to the individual coupling options.
Dies bedeutet jedoch, daß bei angehobenem Container, beispielsweise wenn er sich auf dem LKW befindet oder auf diesen verbracht werden soll, die Handkurbel in einer Höhe deutlich über Kopfhöhe befindet und damit von den Bedienern nur über Hilfsgeräte wie Leitern etc. erreicht und auch nur mit eingeschränkter Kraft bedient werden kann. Dies bedeutet ferner, daß die vier Eckeinheiten am Container möglichst gleichmäßig bedient werden müssen um starke Schräglagert des Containers und damit ein Wegknicken eines der Stützbeine zu verhindern. Dies ist nur durch mindestens vier Mann Bedienungspersonal oder ständiges, abwechselndes Betätigen der vier Eckeinheiten durch einen oder zwei Bediener mit entsprechendem Zeitaufwand möglich.However, this means that when the container is raised, for example when it is on the truck or on This is to be spent, the hand crank is at a height significantly above head height and can therefore only be reached by the operators via auxiliary devices such as ladders etc. and can only be operated with limited force. This also means that the four corner units on the container must be operated as evenly as possible in order to prevent the container from being strongly inclined and thus preventing one of the support legs from buckling. This is only possible by at least four man operating personnel or constant, alternating actuation of the four corner units by one or two operators with the corresponding expenditure of time.
Es ist daher die Aufgabe gemäß der Erfindung, ein Verladegerät für Container zu schaffen, welches mit maximal zwei Mann Bedienungspersonal einfach gehandhabt werden kann und nicht an den vorderen und hinteren Stirnflächen der Container angreift, und dennoch so leicht und einfach aufgebaut ist, daß es während des Transportes des Containers im Laderaum am Container verbleiben kann.It is therefore the object of the invention to provide a loading device for containers which can be handled easily by a maximum of two man operating personnel and does not attack the front and rear end faces of the containers, and yet is so light and simple that it is during of the transport of the container can remain on the container in the loading space.
Bei einem gattungsgemäßen Verladegerät wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen ergeben sich aus den Unteransprüchen.In a generic loading device, this object is achieved by the characterizing features of
Durch die hydraulische Ausbildung der Hebefunktion ist es möglich, die einzelnen Eckeinheiten einerseits einzeln zu handhaben, also an- und abzubauen und auch in ihre Einzelteile (Befestigungsstange Stützfuß, Radeinheit, Abstandshalter) zu zerlegen, und dennoch nach der Montage mit geringem Aufwand eine Wirkverbindung zwischen zwei oder mehr Eckeinheiten herzustellen durch Hydraulikschläuche, die mittels Schnellkupplungen an den einzelnen Eckeinheiten angekoppelt werden.Thanks to the hydraulic design of the lifting function, it is possible to handle the individual corner units individually, i.e. to assemble and disassemble them, and also to disassemble them into their individual parts (fastening rod, support leg, wheel unit, spacer), and yet, after assembly, to establish an effective connection between them with little effort Manufacture two or more corner units using hydraulic hoses that are connected to the individual corner units using quick-release couplings.
Dabei befindet sich der Ölbehälter und die Hydraulikhandpumpe gemeinsam im bzw. am gleichen Bauteil, also beispielsweise dem Abstandshalter oder der Radeinheit, sodaß beim Zerlegen der Eckeinheit in ihre Einzelkomponenten die Pumpe und der Ölbehälter nicht voneinander getrennt werden müssen, und die Gefahr des Falschluft-Eintritts in das System nicht gegeben ist.The oil tank and the hydraulic hand pump are located together in or on the same component, for example the spacer or the wheel unit, so that when the corner unit is disassembled into its individual components, the pump and the Oil containers do not have to be separated from one another, and there is no risk of entry of false air into the system.
Eine Abtrennung der Vorratsbehälter/ Pumpen-Einheit von dem Hydraulikzylinder der gleichen oder einer anderen Eckeinheit über Schläuche und Schnellkupplungen birgt diese Gefahr in weitaus geringerem Maße.A separation of the reservoir / pump unit from the hydraulic cylinder of the same or a different corner unit via hoses and quick couplings hides this danger to a much lesser extent.
Bevorzugt werden die Ölbehälter und die Hydraulikpumpe in dem Abstandshalter zwischen der Befestigungsstange und dem Stützfuß untergebracht, wo einerseits ausreichend Bauraum zur Verfügung steht und andererseits das Beschädigungsrisiko gering ist, da dieser Abstandshalter durch die beiden benachbarten Baugruppen eingeschlossen und damit gut gestützt ist. Eine andere Möglichkeit wäre die Unterbringung an der Radeinheit, die jedoch im Verfahrbetrieb eine exponiertere Lage einnimmt und leichter beschädigt werden kann.The oil containers and the hydraulic pump are preferably accommodated in the spacer between the fastening rod and the support foot, where on the one hand there is sufficient installation space and on the other hand the risk of damage is low, since this spacer is enclosed by the two adjacent assemblies and is therefore well supported. Another possibility would be the accommodation on the wheel unit, which, however, assumes a more exposed position during travel and can be damaged more easily.
Ein zu lösendes Problem besteht darin, den Container gleichmäßig, also ohne Schieflage, trotz evtl. vorhandener Bodenunebenheiten hochzuheben. Bei hergestellter Wirkverbindung zwischen beispielsweise je zwei Eckeinheiten kann durch individuelles Anheben der einzelnen Eckeinheiten der Container zunächst in eine waagrechte Lage gebracht werden, und anschließend durch Parallelschaltung der miteinander wirkverbundenen Eckeinheiten der Container gleichmäßig hochgepumpt werden.One problem to be solved is to lift the container evenly, i.e. without any skew, despite any unevenness in the floor. When an active connection is established between, for example, two corner units, the containers can first be brought into a horizontal position by individually lifting the individual corner units, and then the containers can be pumped up evenly by connecting the corner units connected to one another in parallel.
Dabei ist zu beachten, daß bei Unterbringung der Hydraulikhandpumpe im Abstandshalter sich die Position der Handpumpe mit der Höhenlage des Containers verändert. Bei Anlieferung mittels LKW befindet sich somit die Handpumpe über der Bodenfläche des Containers, und damit deutlich über Kopfhöhe, etwa in Höhe von 2,30 m.It should be noted that when the hydraulic hand pump is accommodated in the spacer, the position of the hand pump changes with the height of the container. When delivered by truck, the hand pump is located above the bottom surface of the container, and thus clearly above head height, approximately at a height of 2.30 m.
Bei Verwendung der üblichen Handkurbeln für den Betrieb einer hydraulischen Handpumpe muß der Bediener aufgrund dieser Höhe unbedingt auf ein Hilfsgerät, eine Leiter oder ähnliches, zur Betätigung steigen, und kann dadurch auch nur mit beschränktem Krafteinsatz in dieser Höhe arbeiten. Die erfindungsgemäß verwendete Ratsche, die die in der Regel als Achsialkolbenpunkte ausgebildete Hydraulikhandpumpe antreibt, weißt dagegen beispielsweise einen Sechskant auf, auf den eine entsprechend lange Querstange als Betätigungshebel aufgesetzt und vom Bediener als Hebelarm betätigt werden kann. Je nach Höhenlage des Vielkantes wird diese Querstange entweder direkt nach unten abstrebend, oder waagrecht abstrebend aufgestockt, und kann dadurch unter allen Umständen vom Bediener mit vollem Krafteinsatz unabhängig von der Höhenlage des Containers und damit der Hydraulikpumpe betätigt werden.When using the usual hand cranks for the operation of a hydraulic hand pump, the operator necessarily has to climb onto an auxiliary device, a ladder or the like for actuation due to this height, and can therefore only with limited use of force at this height. The ratchet used according to the invention, which drives the hydraulic hand pump, which is usually designed as an axial piston point, on the other hand, for example, has a hexagon on which a correspondingly long crossbar can be placed as an actuating lever and can be actuated by the operator as a lever arm. Depending on the height of the polygon, this crossbar is either braced directly downwards or horizontally braced, and can therefore be operated by the operator with full force regardless of the height of the container and thus the hydraulic pump.
Wenn somit die entlang einer Längsseite des Containers angebrachten beiden Eckeinheiten jeweils hydraulisch miteinander verbunden sind, ist es ausreichend, wenn jeweils nur eine der beiden miteinander gekoppelten Eckeinheiten eine Handpumpe und einen Ventilblock zum Einstellen der hydraulischen Funktion aufweist. Der Ventilblock kommt dann mit sechs Schaltstellungen aus, in denen jeweils 2 mal fünf Anschlüsse miteinander zu verbinden sind.If the two corner units attached along a longitudinal side of the container are each hydraulically connected to one another, it is sufficient if only one of the two corner units coupled to one another has a hand pump and a valve block for setting the hydraulic function. The valve block then comes out with six switch positions, in which two times five connections are to be connected to each other.
Bei Kopplung der vier Eckeinheiten sind dagegen zum individuellen Ansteuern aller vier Eckeinheiten einzeln oder gekoppelt bereits 18 Schaltstellungen notwendig, sodaß sich ein Ventilblock ergeben würde, dessen Baugröße deutlich größer wäre als die Summe der beiden Ventilblöcke, wie sie bei Kopplungsmöglichkeiten von nur jeweils zwei Eckeinheiten notwendig sind.When the four corner units are coupled, on the other hand, 18 switching positions are already required for individually controlling all four corner units individually or coupled, so that a valve block would result whose size would be significantly larger than the sum of the two valve blocks, as is necessary with coupling options of only two corner units each are.
Da auf der anderen Seite zum Zusammensetzen der Eckeinheiten aus den einzelnen Baugruppen aufgrund der Größe und des Gewichtes der einzelnen Baugruppen ohnehin zwei Mann Bedienpersonal notwendig sind, und dies auch für das Lenken beim Verfahren der Container mittels des Verladegerätes notwendig ist, besteht die bevorzugte Ausführungsform in der hydraulischen Kopplung von jeweils zwei Eckeinheiten, da dies den baulichen Aufwand reduziert.On the other hand, because the size and weight of the individual modules require two man operating personnel to assemble the corner units from the individual modules, and this is also necessary for steering when moving the containers by means of the loading device, the preferred embodiment consists in the hydraulic coupling of two corner units, as this reduces the construction effort.
Da der Abstandshalter der Eckeinheit zusammen mit dem Stützfuß während des Lufttransportes möglichst nahe an den Container in eine nahezu parallele Lage herangeklappt werden soll, soll die Dicke des Abstandshalters nicht größer sein als die Dicke der Befestigungsstange bzw. des ausfahrbaren Stützfusses. Diese beträgt aus Stabilitätsgründen annähernd 20 cm.Since the spacer of the corner unit together with the support foot is to be folded as close as possible to the container in an almost parallel position during the air transport, the thickness of the spacer should not be greater than the thickness of the fastening rod or of the extendable support foot. For reasons of stability, this is approximately 20 cm.
Aus Gründen der Bedienungsfreundlichkeit soll die Verstellung des Ventilblockes auf der gut zugänglichen vorderen Breitseite des Abstandshalters vorgenommen werden können. Aus diesem Grund ist der Ventilblock als verschwenkbare Welle ausgebildet, die sich durch die maximal 20 cm große Tiefe des Abstandshalters hindurch erstreckt und mit einer ausreichend großen, übersichtlichen Wählscheibe auf der Vorderfront des Abstandshalters gekoppelt ist, und bei zwei miteinander koppelbaren Eckeinheiten insgesamt sechs Schaltstellungen, nämlich Ansteuerung der einen Eckeinheit separat, Ansteuerung der anderen Eckeinheit separat, Ansteuerung der beiden gekoppelten Eckeinheiten gemeinsam, und dies jeweils unterschieden für Heben und Senken, aufweist.For ease of use, the valve block should be able to be adjusted on the easily accessible front broad side of the spacer. For this reason, the valve block is designed as a pivotable shaft that extends through the maximum 20 cm depth of the spacer and is coupled to a sufficiently large, clear dial on the front of the spacer, and with two corner units that can be coupled together, a total of six switch positions, namely control of one corner unit separately, control of the other corner unit separately, control of the two coupled corner units together, and this each differentiated for lifting and lowering.
Obwohl der Stützfuß aus Stabilitätsgründen in seinem Außendurchmesser nicht beliebig verkleinert werden kann, reicht zum Aufbringen der entsprechenden Hebekraft ein deutlich kleinerer Hydraulikzylinder aus.Although the outer diameter of the support leg cannot be reduced arbitrarily for reasons of stability, a significantly smaller hydraulic cylinder is sufficient to apply the corresponding lifting force.
Um die in dem System aufgenommene Menge an Hydrauliköl und damit das Gesamtgewicht der Anlage zu reduzieren, wird vorzugsweise das Stützbein mit drei ineinander verschiebbaren Segmenten ausgebildet, wobei sich im mittleren Segment nicht ein einziger großer, sondern parallel nebeneinander zwei kleine Hydraulikzylinder befinden, von denen der eine das erste und der andere das letzte der drei ineinanderlaufenden Segmente gegenüber dem mittleren Segment verschieben kann. Durch die Verwendung zweier wesentlich kleinerer Hydraulikzylinder wird die Ölmenge auf etwa ein Fünftel verringert.In order to reduce the amount of hydraulic oil absorbed in the system and thus the total weight of the system, the support leg is preferably formed with three segments which can be pushed into one another, with not a single large but parallel two small hydraulic cylinders, of which the is located in the middle segment one can shift the first and the other the last of the three merging segments with respect to the middle segment. By using two significantly smaller hydraulic cylinders, the amount of oil is reduced to about a fifth.
Bei einer solchen Lösung wäre es auch möglich, zusätzlich zu den beiden Hydraulikzylindern auch den Ölvorratsbehälter sowie die Handpumpe im Inneren des mittleren Segmentes aufzunehmen. Die drei Segmente dürfen dann jedoch nur soweit ineinander verfahrbar sein, daß die Zugänglichkeit des Vielkantes für die Hydraulikpumpe auch im vollständig eingefahrenen Zustand noch gewährleistet ist. Dies bedingt eine insgesamt größere Baulänge des Stützfusses.With such a solution, it would also be possible, in addition to the two hydraulic cylinders, to also accommodate the oil reservoir and the hand pump in the interior of the middle segment. However, the three segments must then only be able to be moved into one another to such an extent that the accessibility of the polygon for the hydraulic pump is still guaranteed even when the state is completely retracted. This requires an overall longer overall length of the support foot.
Die einzelnen Baugruppen jeder Eckeinheit werden über formschlüssige Verbindungen ineinandergesteckt und mittels Durchsteckbolzen gesichert, sodaß von zwei Mann, notfalls auch nur von einem einzigen, die gesamte Eckeinheit aus den Baugruppen nacheinander zusammengesteckt werden kann, wobei die einzelnen Baugruppen ein Gewicht aufweisen, welches noch von einem einzelnen Mann gehandhabt werden kann.The individual assemblies of each corner unit are plugged into one another via positive connections and secured by means of push-through bolts, so that the entire corner unit can be assembled from the assemblies one after the other by two men, if necessary only by one, the individual assemblies having a weight that is still one single man can be handled.
Beim Abnehmen eines mittels LKW angelieferten Containers und Verbringen in ein Transportflugzeug läuft dies so ab, daß zunächst die Befestigungsstangen an den vier Außenkanten des Containers zu befestigen sind. Dabei dürfen die vorderen und hinteren Stirnflächen des Containers nicht bedeckt sein, da von dieser Seite her bei manchen Containern zusätzliche Bauteile angeordnet werden müssen.When removing a container delivered by truck and placing it in a transport plane, this takes place in such a way that the fastening rods must first be fastened to the four outer edges of the container. The front and rear end faces of the container must not be covered, since additional components must be arranged from this side for some containers.
Die Befestigungsstangen werden daher von den Längsseiten her an den oberen und unteren Eckverschlüssen parallel zu den senkrechten Außenkanten des Containers angeordnet, in dem entsprechend den Abmessungen des Containers zunächst der Einhängekopf in der richtigen Lage an der Befestigungsstange arretiert wird, und dann der Einhängekopf mit seinem von oben nach unten ragenden Einhängebolzen von oben her in die Bohrung des oberen Eckverschlusses eingehängt wird. Dann befindet sich das untere Ende der Befestigungsstange parallel außen in der Anlage an dem unteren Eckverschluss, sodaß mittels eines Handrades in bekannter Weise ein Knebel innerhalb des Langloches des Eckverschlusses verdreht und festgepannt werden kann, sodaß die Befestigungsstange formschiüssig mit dem Container verbunden ist und ausreichende Kräfte aufnehmen kann, um den Container hochzuheben.The fastening rods are therefore arranged from the long sides on the upper and lower corner locks parallel to the vertical outer edges of the container, in which the suspension head is first locked in the correct position on the fastening rod in accordance with the dimensions of the container, and then the suspension head with its from hanging bolts protruding downwards from above into the hole in the upper corner lock. Then the lower end of the fastening rod is located parallel outside in the system on the lower corner lock, so that a toggle can be rotated and tightened in a known manner within the elongated hole of the corner lock by means of a handwheel, so that the fastening rod is form-fitting is connected to the container and can absorb sufficient forces to lift the container.
Zum Anordnen der übrigen Baugruppen an der Befestigungsstange wird zunächst an der separaten Radeinheit, die aus einem Drehteller mit darunter mit Nachlauf angeordneten Doppelrollen besteht,ein Stütztrapez angesetzt, welches an seinen am weitesten auseinanderliegenden, und tief über dem Untergrund angeordneten Enden kleine Stützrollen aufweist. Durch wenigstens eine Stellschraube kann die Neigung des Stütztrapezes gegenüber der Radeinheit verstellt und damit der Drehteller der Radeinheit waagrecht eingestellt werden.To arrange the other assemblies on the mounting rod, a support trapezoid is first attached to the separate wheel unit, which consists of a turntable with double rollers arranged underneath with a caster, which has small support rollers at its most widely spaced ends and located deep above the ground. The inclination of the support trapezoid relative to the wheel unit can be adjusted by at least one adjusting screw and the turntable of the wheel unit can thus be adjusted horizontally.
Nachdem dies geschehen ist wird in einen Führungsschuh auf der Oberseite des Drehtellers der Radeinheit, welcher nur nach einer Seite hin offen ist, entsprechend geformter Einführblock, der sich am unteren Ende des Stützfusses befindet, eigeschoben und mittels Durchsteckbolzen eine feste Verbindung zwischen Stützfuß und Radeinheit hergestellt.After this has been done, a correspondingly shaped insertion block, which is located at the lower end of the support foot, is inserted into a guide shoe on the top of the turntable of the wheel unit, which is only open on one side, and a fixed connection between the support foot and the wheel unit is made by means of push-through bolts .
Da der Stützfuß ca. 1,80 m hoch und etwa einen Zentner schwer ist, ist die vorherige Nivellierung der Radeinheit mittels des Stütztrapezes notwendig, damit bei aufgesetztem Stützfuß nicht die gesamte Einheit umkippt.As the support leg is approx. 1.80 m high and weighs approximately one hundredweight, the wheel unit must be leveled beforehand using the trapezoid so that the entire unit does not tip over when the support leg is attached.
An dem Stützfuß wird nun mittels zweier Durchsteckbolzen der gesamte Abstandshalter befestigt und mittels hydraulischer Schnellkupplungen mit den im Inneren des Stützfusses befindlichen Hydraulikzylindern verbunden.The entire spacer is now attached to the support leg by means of two push-through bolts and connected to the hydraulic cylinders located in the interior of the support leg by means of hydraulic quick couplings.
Anschließend wird der Stützfuß und damit der Abstandshalter mittels der Handpumpe vom Bediener in eine solche Höhe ausgefahren, daß sich der Abstandshalter auf der Höhe der entsprechenden Befestigungslaschen der am Container befestigten Befestigungsstange befindet. Sobald dies erreicht ist, wird die Radeinheit mit dem hochgefahrenen Stützfuß gegen die Befestigungsstange verfahren und mittels senkrecht geführter Durchsteckbolzen gesichert, wobei in der Regel der Abstandshalter und der Stützfuß quer zur Längsachse des Containers, also rechtwinklig auf die seitliche Außenfläche des Containers zu, verfahren wird und rechtwinklig von dieser absteht, sodaß die einzelnen Radeinheiten der vier Eckeinheiten in Querrichtung des Containers maximalen Stützabstand voneinander besitzen.Subsequently, the support foot and thus the spacer is extended by the operator to such a height by means of the hand pump that the spacer is at the height of the corresponding fastening tabs of the fastening rod fastened to the container. As soon as this is achieved, the wheel unit is moved with the raised support foot against the fastening rod and secured by means of vertically guided push-through bolts, with the spacer and the support foot generally transverse to the longitudinal axis of the Containers, so at right angles to the lateral outer surface of the container, is moved and protrudes at right angles from this, so that the individual wheel units of the four corner units in the transverse direction of the container have a maximum support distance from each other.
Nachdem alle vier Eckeinheiten auf diese Art und Weise mit dem Container fest verbunden sind, wird der Container zusätzlich angehoben, um außer Kontakt zu dem LKW-Fahrgestell zu geraten, und den LKW unter dem Container herauszufahren. Anschließend wird der Container bis knapp über Boden abgesenkt, um einerseits eine tiefe Schwerpunktlage zu erzielen und andererseits noch eine Verfahrmöglichkeit sowie das Verbringen in das Luftfahrzeug zu ermöglichen. Je nach Beschaffenheit des Untergrundes ist dabei ein Ausgleich von Bodenunebenheiten durch Ausfahren oder Einfahren einzelner Eckeinheiten oder Paaren von Eckeinheiten notwendig.After all four corner units have been firmly connected to the container in this way, the container is additionally raised in order to get out of contact with the truck chassis and to pull the truck out from under the container. The container is then lowered to just above the ground, on the one hand to achieve a low center of gravity and, on the other hand, to allow it to be moved and brought into the aircraft. Depending on the nature of the subsoil, it is necessary to compensate for uneven floors by extending or retracting individual corner units or pairs of corner units.
Vor dem Verbringen in das Luftfahrzeug sind weiterhin die Abstandshalter um die Durchsteckbolzen herum, die die Verbindung zur Befestigungsstange darstellen, soweit zu verschwenken, daß sich der Stützfuß und die Radeinheit innerhalb der Außenkanten der am Container ortsfest angeordneten Befestigungsstange befinden. Dies ist notwendig, da einerseits außerhalb des Containers nicht genügend Raum innerhalb des Luftfahrzeuges zu Verfügung steht, und andererseits fest vorgegebene Belastungsbahnen innerhalb der Auffahrrampe in das Luftfahrzeug existieren, auf deren Abstand die Abstände der Radeinheiten eingestellt werden müssen. Dies erfolgt durch Justierung der Drehlage der Abstandshalter gegenüber der Durchsteckbolzen der Befestigungsstange durch Einstecken von Justierbolzen in entsprechende Bohrungen der Befestigungslaschen der Befestigungsstange, sodaß durch unterschiedliche Bohrungen auch unterschiedliche Stellungen der Radeinheit gegenüber der Befestigungsstange justierbar sind.Before being brought into the aircraft, the spacers around the push-through bolts, which represent the connection to the fastening rod, must also be pivoted to such an extent that the support foot and the wheel unit are located within the outer edges of the fastening rod arranged in a stationary manner on the container. This is necessary because, on the one hand, there is not enough space inside the aircraft outside of the container, and on the other hand there are predetermined load paths within the ramp into the aircraft, the spacing of which must be set to the distances between the wheel units. This is done by adjusting the rotational position of the spacers relative to the push-through bolts of the fastening rod by inserting adjusting bolts into corresponding bores of the fastening lugs of the fastening rod, so that different positions of the wheel unit relative to the fastening rod can also be adjusted through different bores.
Mittels einer Zugdeichsel, die an den unteren Enden zweier stirnseitiger Eckeinheiten befestigbar ist, kann der Container über die Rampe in das Luftfahrzeug entweder mittels Winde hineingezogen oder mittels eines Fahrzeuges hineingeschoben werden. Dabei wird der Container gelenkt mit Hilfe einer Lenkstange, die an jeder der vier Radeinheiten befestigt und von einem Bediener manuell geführt werden kann, wodurch entweder ein Lenken der in Fahrtrichtung vorderen Radeinheiten möglich ist (die zwei in Fahrtrichtung vorderen Radeinheiten können dabei auch mittels einer sehverbindenden Spurstange parallel gelenkt werden), oder auch die in Fahrtrichtung rückwertigen Eckeinheiten aus der Geardeausrichtung herausgelenkt werden, die sie normalerweise aufgrund des bei allen Radeinheiten vorhandenen Nachlaufes einnehmen.Using a drawbar that can be attached to the lower ends of two front corner units, the container can be ramped into the aircraft either by means of a winch be pulled in or pushed in by means of a vehicle. The container is steered with the help of a handlebar, which is attached to each of the four wheel units and can be guided manually by an operator, whereby either steering of the front wheel units in the direction of travel is possible (the two wheel units at the front in the direction of travel can also be connected by means of a visual connection Tie rod are steered in parallel), or the corner units that are reversed in the direction of travel are deflected out of the gear alignment, which they normally take due to the caster that is present in all wheel units.

In der Aufsicht der Figur 1 ist ein mit vier Eckeinheiten (1) sowie einer Zugdeichsel (33) und zwei Längsstangen (32) sowei einem Querlenker (30) ausgestatteter Container dargestellt.1 shows a container equipped with four corner units (1) and a drawbar (33) and two longitudinal bars (32) and a wishbone (30).
Dabei sind die beiden Eckeinheiten (1) der oberen Bildhälfte nicht miteinander hydraulisch wirkverbunden, während die beiden Eckeinheiten (1) der unteren Bildhälfte über Hydraulikleitungen (7) miteinander in Verbindung stehen.The two corner units (1) in the upper half of the figure are not hydraulically operatively connected to one another, while the two corner units (1) in the lower half of the figure are connected to one another via hydraulic lines (7).
Zusätzlich ist die rechte Eckeinheit (1) in der unteren Bildhälfte noch mit dem Stütztrapez (20) und damit den Stützrädern (21) ausgestattet, un befindet sich in der ausgeklappten Position, wobei sich die Radeinheit (4) dieser Eckeinheit in der am weistesten von der seitlichen Außenfläche des Containers entfernten Position, also unter etwa 90° von dieser abstrebend, auf der Höhe der vorderen Kante des Containers befindet.In addition, the right corner unit (1) in the lower half of the figure is still equipped with the trapezoid (20) and thus the support wheels (21), and is in the extended position, the wheel unit (4) of this corner unit being in the most wise of the lateral outer surface of the container distant position, ie striving at about 90 ° from it, is located at the level of the front edge of the container.
Die anderen drei Eckeinheiten (1) befinden sich bereits in der eingeklappten Position, in der sich die Radeinheiten (4) innerhalb der Außenkanten der Befestigungsstangen (2) befinden, welche für das Einfahren des Containers in das enge Luftfahrzeug benutzt wird. In dieser Stellung sind die Abstandshalter (5) gegenüber den Befestigungsstangen (2) durch eingesetzte Justierbolzen (37) festgelegt, welche durch dann fluchtende Bohrungen (38) von Abstandshalter (5) und den Befestigungslaschen (23') der Befestigungsstangen (2) sich hindurch erstrecken.The other three corner units (1) are already in the folded position, in which the wheel units (4) are located within the outer edges of the fastening rods (2), which are used for moving the container into the narrow aircraft. In this position, the spacers (5) are fixed relative to the fastening rods (2) by inserted adjusting bolts (37), which pass through then aligned bores (38) of the spacer (5) and the fastening lugs (23 ') of the fastening rods (2) extend.
Zum Anbauen der Eckeinheiten am Container und zum Verfahren des Containers außerhalb der beengten Verhältnisse eines Luftfahrzeuges ragen die Abstandshalter (5) und damit die Radeinheiten (4) wie bei der rechten unteren Eckeinheit der Figur 1 senkrecht von den Längsaußenwänden des Containers abstrebend nach außen, um eine möglichst große Stützbreite beim Verfahren zu bieten.To attach the corner units to the container and to move the container outside the confined space of an aircraft, the spacers (5) and thus the wheel units (4) protrude vertically from the longitudinal outer walls of the container, as in the lower right corner unit of Figure 1 to offer the largest possible support width during the process.
Dabei wird der Container mittels einer Zugdeichsel (33) bewegt, die an den unteren Enden der Befestigungsstangen (2), und zwar dort angebrachten Augen (36), eingenhängt werden kann, und von jedem Zugfahrzeug gezogen werden kann.The container is moved by means of a drawbar (33) which can be attached to the lower ends of the fastening rods (2), namely eyes (36) attached there, and can be pulled by any towing vehicle.
Aufgrund des Nachlaufes der Räder (16) jeder Radeinheit (4) läuft dabei der Container - bei ebenem Untergrund - hinter dem Zugfahrzeug, kann jedoch durch Lenkstangen (32), die an den Radeinheiten (4) montierbar sind, in jeder gewünschten Weise sowohl der vorderen als auch der hinteren Radeinheit (4) gesteuert werden. Um zwei Radeinheiten (4) zu koppeln, können diese an einen Querlenker (30) gekoppelt werden, der an seinen Enden Bohrungen aufweist, die auf entsprechende Bolzen (31') der Radeinheiten (4) aufsteckbar sind, entsprechend dem gewünschten gegenseitigen Abstand der Radeinheiten (4).Due to the caster of the wheels (16) of each wheel unit (4), the container runs behind the towing vehicle - on a level surface - but can be mounted in any desired manner using handlebars (32) that can be mounted on the wheel units (4) front and the rear wheel unit (4) can be controlled. To couple two wheel units (4) these are coupled to a wishbone (30) which has at its ends bores which can be plugged onto corresponding bolts (31 ') of the wheel units (4), in accordance with the desired mutual distance between the wheel units (4).
Wie in Figur 1 zu erkennen, werden die Befestigungsstangen (2) außen, also von den Längsseiten des Containers her, auf die an jeder Ecke des Containers vorhandenen Eckverschlüsse aufgesetzt. Dabei liegt jede Befestigungsstange (2) mit einer Oberplatte (34) auf der Oberseite des Containers auf, wobei sich von dieser Oberplatte (34) aus ein besser z.B. in Figur 4 zu erkennender Einhängezapfen (35) nach unten in die Öffnung des Eckbeschlages (40) des Containers hineinerstreckt.As can be seen in FIG. 1, the fastening rods (2) are placed on the outside, that is to say from the long sides of the container, on the corner closures present at each corner of the container. Each fastening rod (2) rests with an upper plate (34) on the top of the container, a better e.g. The hanging pin (35) shown in FIG. 4 extends downward into the opening of the corner fitting (40) of the container.
Die Befestigungsstangnen (2) verlaufen in der Nähe der senkrechten Außenkanten des Containers eng anliegend an diesem nach unten, wobei über die Befestigungsstange (2) nach außen die Befestigungslaschen (23') zum Anordnen der Abstandshalter (5) mit den Stützfüßen (3) abstreben.The fastening rods (2) run close to the vertical outer edges of the container downwards, with the fastening lugs (23 ') striving to arrange the spacers (5) with the support feet (3) over the fastening rod (2) .
Dabei können die Radeinheiten (4) soweit nach innen geklappt werden, daß sie sich etwa im selben Abstand wie die Eckbeschläge (40) zur Längsmittelachse der Container befinden, also noch innerhalb der Außenkanten der Befestigungsstangen (2), und damit noch innerhalb des Hüllprofiles des aufnehmenden Luftfahrzeuges, wie in Figur 4 dargestellt.The wheel units (4) can be folded in so far that they are located approximately at the same distance as the corner fittings (40) from the longitudinal central axis of the container, i.e. within the outer edges of the mounting rods (2), and thus within the envelope profile of the receiving aircraft, as shown in Figure 4.
Nach dem Positionieren des Containers im Luftfahrzeug und dem Absetzen des Containers können die vom Boden abgehobenen Radeinheiten (4) soweit nach innen geklappt werden, daß die Abstandshalter (5) annähernd parallel an den vorderen und hinteren Stirnflächen der Container anliegen.After the container has been positioned in the aircraft and the container has been set down, the wheel units (4) lifted off the ground can be folded inwards to such an extent that the spacers (5) lie approximately parallel to the front and rear end faces of the containers.
Die Deichsel (33) ist mittels Augen (36) und Handräder (39) an den auf der vorderen und hinteren Stirnfläche sichtbaren Teil der Eckbeschläge (40) befestigt. Die Figuren 2a bis 2c zeigen die Schritte des Aufbaus einer Eckeinheit, um diese an der Ecke eines beispielsweise hochliegenden Containers auf einem LKW, wie in Figur 3 dargestellt, zu befestigen.The drawbar (33) is attached by means of eyes (36) and handwheels (39) to the part of the corner fittings (40) visible on the front and rear end faces. FIGS. 2a to 2c show the steps of assembling a corner unit in order to attach it to the corner of, for example, a high-lying container on a truck, as shown in FIG. 3.
Zu diesem Zweck wird gemäß Figur 2a zunächst an der Radeinheit (4), die aus einem Führungsschuh (18) besteht, unter welchem und drehbar um eine im wesentlichen sekrechte Achse gegenüber dem Führungsschuh (18) ein Drehteller (17) angeordnet ist, in welchem parallel zueinander zwei Räder (16), vorzugsweise vollgummibereift, gelagert sind, und zwar außerhalb der senkrechten Drehachse (47) zwischen dem Führungsschuh (18) und dem Drehteller (17), also mit Nachlauf.For this purpose, according to FIG. 2a, a turntable (17) is arranged on the wheel unit (4), which consists of a guide shoe (18), under which and rotatable about an essentially perpendicular axis relative to the guide shoe (18) Two wheels (16), preferably with full rubber tires, are mounted parallel to one another, specifically outside the vertical axis of rotation (47) between the guide shoe (18) and the turntable (17), that is to say with caster.
Auf der gleichen Seite der Drehachse (47) wie die Räder (16) sind an dem Drehteller (17) aufragende Bolzen (31') bzw. Laschen (31) abstebend angeordnet, um auf die Bolzen (31') einen Querlenker (30) aufzustecken, oder an den Laschen (31) eine Lenkstange (32).On the same side of the axis of rotation (47) as the wheels (16), bolts (31 ') or brackets (31) projecting from the turntable (17) are arranged so as to lift off a wishbone (30) on the bolts (31'). plug on, or on the tabs (31) a handlebar (32).
Auf der gegenüberliegenden Seite der Drehachse (47) ist ein Stützradtrapez (20) um eine Achse (42) verschwenkbar am Drehteller (17) angeordnet, wobei die Streben des Stützradtrapezes (20) im wesentlichen schräg nach unten gegen den Untergrund ragen, und an ihren tiefliegenden Enden Stützräder (21) aufweisen. Die Neigung des Drehtellers (17) und damit der gesamten Radeinheit (4) kann durch Verstellen einer Stellschraube (41) und damit der Relativlage zwischen dem Stützradtrapez (20) und dem Drehteller (17) eingestellt werden.On the opposite side of the axis of rotation (47) a support wheel trapezoid (20) about an axis (42) is arranged on the turntable (17), the struts of the support wheel trapezoid (20) projecting substantially obliquely downwards against the ground, and on them low-lying ends have support wheels (21). The inclination of the turntable (17) and thus the entire wheel unit (4) can be adjusted by adjusting an adjusting screw (41) and thus the relative position between the trapezoidal trapezoidal wheel (20) and the turntable (17).
Wie Figur 2b zeigt, wird nach dem Waagrechtstellen des Drehtellers (17) ein in den Führungsschuh (18) des Drehtellers (17) hineinpassender Einführblock (19), der sich am unteren, ausfahrbaren Ende des Stützfusses (3) befindet, von der einen, offenen Seite in den Führungsschuh (18) eingeschoben und dort mittels Durchsteckbolzen (22) gesichert.As FIG. 2b shows, after the turntable (17) has been placed horizontally, an insertion block (19) which fits into the guide shoe (18) of the turntable (17) and is located at the lower, extendable end of the support foot (3), one of which open side inserted into the guide shoe (18) and secured there by means of push-through bolts (22).
An dem Oberteil (43) des Stützfusses (3) sind in einem definierten Abstand zueinander zwei Befestigungslaschen (23) angeordnet, die einerseits in die gleiche Richtung abstreben und Durchgangsbohrungen aufweisen, um daran mittels Durchsteckbolzen (22) den Abstandshalter (5) zu befestigen, wie in Figur 2c dargestellt. Ferner weist jede Befestigungslasche (23) eine annähernd kreisringförmig um den Stützpunkt (3) im Abstand umlaufende Griffleiste (24) auf, die dem Führen des Stützfusses (3) dient.On the upper part (43) of the support foot (3) two fastening tabs (23) are arranged at a defined distance from each other, which strive in the same direction on the one hand and have through-bores in order to fasten the spacer (5) to it by means of push-through bolts (22), as shown in Figure 2c. Furthermore, each fastening tab (23) an approximately circular ring around the support point (3) at a distance from the handle bar (24), which serves to guide the support foot (3).
Der in Figur 2c bereits an den Stützfuß (3) angesetzte Abstandshalter (5) besteht im wesentlichen aus oben und unten quer verlaufenden Profilen (25) sowie einem dazwischen angeordneten Gehäuse (26), in dem sich einerseits der Ölbehälter (9) und andererseits die Hydraulik-Handpumpe (8) mit der sie antreibenden Ratsche (11) befindet. Die Hydraulikleitungen (7) des Abstandshalters (5) können dessen Ansetzen mit den Hydraulikleitungen (7) des Stützfusses (3) über Schnellkupplungen (44) verbunden werden.The spacer (5) already attached to the support foot (3) in FIG. 2c essentially consists of profiles (25) which run transversely at the top and bottom, and a housing (26) arranged between them, in which the oil container (9) and the one Hydraulic hand pump (8) with the ratchet (11) driving it. The hydraulic lines (7) of the spacer (5) can be connected to the hydraulic lines (7) of the support foot (3) via quick-release couplings (44).
Ferner ist im Gehäuse (26) die Steuerwelle (13) mit der außen sichtbaren und verdrehbaren Wählscheibe (14) angeordnet, die die einzelnen Ventilschaltungen ermöglicht.Furthermore, the control shaft (13) with the externally visible and rotatable dial (14), which enables the individual valve circuits, is arranged in the housing (26).
Zuletzt muß die Befestigungsstange (2) mit dem bereits montierten Rest der Eckeinheit (1) verbunden werden. Dabei kann entweder die Befestigungsstange (2) vorab am Container befestigt werden, in dem - nach Justierung des Einhängekopfes (27) in der richtigen Höhe an der Befestigungsstange (2) mittels Durchstecklbolzen (22) - der Einhängezapfen (35) der Befestigungsstange (2) von oben her in die entsprechende Öffnung des Eckbeschlages (40) des Containers eingehengt wird. Dadurch liegt die Oberplatte (34) auf der Oberseite des Containers an und erstreckt sich über das Mittelstück (28) des Einhängekopfes (27) schräg nach unten außen zur Befestigungsstange (2), die sich in einem Abstand zur Außenseite des Containers befindet, um dessen Beschädigung zu vermeiden.Finally, the fastening rod (2) must be connected to the rest of the corner unit (1) that has already been installed. Either the mounting rod (2) can be attached to the container beforehand by - after adjusting the mounting head (27) at the correct height on the mounting rod (2) using push-through bolts (22) - the mounting pin (35) of the mounting rod (2) from above into the corresponding opening of the corner fitting (40) of the container. As a result, the top plate (34) rests on the top of the container and extends obliquely downwards over the center piece (28) of the hanging head (27) to the fastening rod (2), which is at a distance from the outside of the container, around the latter To avoid damage.
Am unteren Ende der Befestigungsstange (2) ist diese wiederum zum Container hin gekröpft und weist ein Handrad (46) auf, mit dessen Hilfe der auf der Innenseite der Befestigungsstange mit dem Handrad (46) verbundene Knebel (45) in das Langloch des Eckbeschlages (40) eingebracht, um 90° verdreht und dort verspannt werden kann zur festen Verbindung des unteren Endes der Befestigungsstange (2) mit dem Container, und damit auch der formschlüssigen Verbindung des Einhängezapfens (35) im oberen Eckbeschlag.At the lower end of the fastening rod (2), this in turn is bent towards the container and has a handwheel (46), with the aid of which the toggle (45) connected to the handwheel (46) on the inside of the fastening rod into the slot of the corner fitting ( 40) introduced, rotated by 90 ° and clamped there for a firm connection of the lower end the fastening rod (2) with the container, and thus also the positive connection of the hanging pin (35) in the upper corner fitting.
Anschließend kann der Rest der Eckeinheit (1) durch Ausfahren des Stützfusses (3) auf die Höhe der Befestigungsstange (2) gebracht, an diese herangefahren und mit dieser verbunden werden.The rest of the corner unit (1) can then be brought to the height of the fastening rod (2) by extending the support foot (3), moved up to it and connected to it.
Die übliche Vorgehensweise besteht jedoch darin, die Befestigungsstange (2) ohne vorherige Verbindung mit dem Container an den freien Enden des Abstandshalters (5) zu befestigen, diesmal mittels senkrecht geführter Durchsteckbolzen (22), die sich durch die Befestigungslaschen (23') der Befestigungsstange sowie hierzu fluchtende Bohrungen in den Profilen (25) des Abstandshalters (5) hindurch erstrecken. Zusätzlich wird die Drehlage des Abstandshalters gegenüber diesen Befestigungslaschen (23') durch Justierbolzen (37) festgelegt, die in unterschiedliche Bohrungen der Befestigungslaschen (23') eingreifen können und in Führungsmuffen der Profile (5) mittels einer schraubenförmigen Kulisse (48) geführt sind, um ein Ein- und Ausrasten in die Bohrungen (38) zu ermöglichen.The usual procedure, however, is to fasten the fastening rod (2) to the free ends of the spacer (5) without prior connection to the container, this time by means of vertically guided push-through bolts (22) that pass through the fastening lugs (23 ') of the fastening rod as well as aligned holes in the profiles (25) of the spacer (5). In addition, the rotational position of the spacer relative to these fastening tabs (23 ') is determined by adjusting bolts (37) which can engage in different bores in the fastening tabs (23') and are guided in guide sleeves of the profiles (5) by means of a helical link (48), to enable it to snap into and out of the bores (38).
Nach erfolgter Komplettmontage der Eckeinheit (1), wie in Figur 2c ersichtlich, erfolgt dann das Hochfahren der Einheit auf die dem Container entsprechende Höhe, und das vorher beschriebene Einhängen und Befestigen der Befestigungsstange (2) am Container, wie in Figur 3 für einen auf der Ladefläche eines LKW angelieferten Containers dargestellt.After complete assembly of the corner unit (1), as can be seen in FIG. 2c, the unit is then raised to the height corresponding to the container, and the previously described hanging and fastening of the fastening rod (2) to the container, as in FIG. 3, for one the loading area of a truck delivered container.
Figur 4 zeigt die Ansicht eines mit einer Eckeinheit (1) ausgestatteten Containers bei eingeklappter Radeinheit (4) entsprechend der in Figur 1 in der rechten unteren Bildecke dargestellten Radeinheit (4). Dabei ist zu erkennen, daß sich die gesamte Radeinheit (4) innerhalb der Außenkante der Befestigungsstange (2) befindet, und der Stützfuß (3) sogar innerhalb der Außenkanten des Containers.FIG. 4 shows the view of a container equipped with a corner unit (1) when the wheel unit (4) is folded in, corresponding to the wheel unit (4) shown in the lower right corner of the figure. It can be seen that the entire wheel unit (4) is inside the outer edge of the fastening rod (2), and the support foot (3) is even inside the outer edges of the container.
Das schräg verlaufende Mittelstück (28) verläuft dabei vom oberen Ende der Befestigungsstange (2) zu der unmittelbar und nur ca. 1 cm über die Oberkante des Containers aufragenden Oberplatte (34) des Einhängekopfes (27). Dies bietet den Vorteil, daß sich die gesamte Eckeinheit innerhalb der im Bereich der oberen Ecke der Container sehr nahe an diese heranreichenden Hüllprofiles (49) eines Transportflugzeuges unterbringen läßt.The sloping center piece (28) runs from the upper end of the fastening rod (2) to the upper plate (34) of the hanging head (27) which rises directly and only approx. 1 cm above the upper edge of the container. This offers the advantage that the entire corner unit can be accommodated within the envelope profile (49) of a transport aircraft that comes very close to this in the area of the upper corner of the container.
Figur 5 zeigt eine Teilschnittdarstellung eines Stützfusses (3), bei dem dessen Oberteil (43) das erste Segment (3a) von drei ineinander fahrbaren Segmenten (3a bis 3c) darstellt, von denen das unterste Segment (3c) mit der Radeinheit (4) verbunden ist. Die notwendige Hebekraft für den Container erfordert jedoch bei weitem keinen Hydraulikzylinder, der den Außenabmessungen des aus Stabilitätsgründen groß gewählten Stützfusses (3) entspricht. Deshalb sind innerhalb des mittleren Segmentes (3b) parallel nebeneinander zwei Hydraulikzylinder (6a und 6b) angeordnet, die ihre Hydraulikkolben (15a und 15b) in entgegengesetzte Richtungen ausstoßen können, und diese Hydraulikkolben (15a und 15b) mit dem oberen Segment (3a), also dem Oberteil (43), einerseits sowie dem unteren Segment (3c) andererseits verbunden sind.FIG. 5 shows a partial sectional view of a support foot (3), in which the upper part (43) represents the first segment (3a) of three segments (3a to 3c) which can be moved into one another, the lowest segment (3c) with the wheel unit (4) connected is. However, the necessary lifting force for the container by no means requires a hydraulic cylinder that corresponds to the external dimensions of the support leg (3), which is large for stability reasons. For this reason, two hydraulic cylinders (6a and 6b), which can eject their hydraulic pistons (15a and 15b) in opposite directions, are arranged in parallel within the middle segment (3b), and these hydraulic pistons (15a and 15b) with the upper segment (3a), that is, the upper part (43), on the one hand, and the lower segment (3c), on the other hand, are connected.
Die einzelnen Hydraulikzylinder (6a und 6b) haben dabei einen Durchmesser von nur etwa 4 cm, wodurch die benötigte Ölmenge drastisch reduziert wird.The individual hydraulic cylinders (6a and 6b) have a diameter of only about 4 cm, which drastically reduces the amount of oil required.
In Figur 5 sind ferner schematisch der Ölbehälter (9) und die hydraulische Handpumpe (8) in dem nicht mit dem Drehteller (17) gegenüber dem Stützfuß (3) mitdrehenden Oberteil der Radeinheit (4) untergebracht, wodurch die Möglichkeit besteht, Radeinheit (4) und Stützfuß (3) gemeinsam an der Befestigungsstange (2) abzunehmen, und dadurch die Schnellkupplungen zwischen Pumpe und Ölbehälter einerseits und den Hydraulikkolben andererseits nicht trennen zu müssen.In Figure 5, the oil tank (9) and the hydraulic hand pump (8) are also housed in the upper part of the wheel unit (4) which does not rotate with the turntable (17) with respect to the support leg (3), so that there is the possibility of wheel unit (4 ) and support leg (3) together on the mounting rod (2), so that you do not have to separate the quick couplings between the pump and oil tank on the one hand and the hydraulic pistons on the other.
Zusätzlich ist es möglich, wie in Figur 2c gestrichelt eingezeichnet, in dem Gehäuse (26) des Abstandshalters (5) zusätzlich zu der in der Regel als Kolbenpumpe ausgebildeten Handpumpe (8) eine kleine Zahnradpumpe (50) unterzubringen, die mit einem Elektromotor gekoppelt ist, welcher vom anliefernden LKW oder dem Luftfahrzeug aus mit Strom versorgt werden kann, um die Pumpphase zu beschleunigen und anzukürzen.In addition, as shown in dashed lines in FIG. 2c, it is possible in the housing (26) of the spacer (5) in addition to the one which is generally designed as a piston pump Hand pump (8) to accommodate a small gear pump (50) which is coupled to an electric motor which can be supplied with power from the delivering truck or the aircraft in order to accelerate and shorten the pumping phase.
