Description

BESCHREIBUNG DESCRIPTION

" LADEVORRICHTUNG ""CHARGER"

Es ist eine Vorrichtung, welche das Verschieben von La sten auf den Ladeflächen von Transportfahrzeugen erleich tert aus der Beschreibung der IT-Patentanmeldung N.4802/ A83, des selben Anmelders bekannt, weiters ist eine Ver¬ schiebevorrichtung ür Lasten aus der US 541743 sowie eine Vorrichtung zum schellen Verschieben der Ladung, ins besondere auf Transportfahzeugen, aus der FR 8106855 be¬ kannt.It is a device which facilitates the shifting of loads on the loading areas of transport vehicles from the description of IT patent application N.4802 / A83, by the same applicant, furthermore a shifting device for loads from US 541743 and a Device for quickly moving the load, especially on transport vehicles, known from FR 8106855.

Diese bekannten Vorrichtungen ermöglichen es jedoch nicht, trotz Einsatz von teilweise festen, teilweise mechanisch verstellbaren Wälzorganen, zum Beispiel einen Teil der La düng zu verschieben und die gesamte Ladung oder nur einen Teil davon hydraulisch zu heben.However, these known devices do not make it possible, despite the use of partially fixed, partially mechanically adjustable rolling elements, for example to shift part of the load and to lift all or part of the load hydraulically.

Die Erfindung stellt sich die Aufgabe eine Vorrichtung zu schaffen um die gesamte Last oder nur einen Teil da¬ von auf der Ladefläche eines Fahrzeuges oder einer festen oder mobilen Verladerampe anheben und verschieben zu kön¬ nen, um eine maximale Vielseitigkeit der Vorrichtung sowie die Anpassungsfähigkeit dieser an die Art der Ladung oder/ und des Einsatzes zu erreichen.The object of the invention is to create a device in order to be able to lift and move the entire load or only a part thereof on the loading surface of a vehicle or a fixed or mobile loading ramp, in order to achieve maximum versatility of the device and the adaptability thereof to achieve the type of cargo and / or use.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, auf einem einzigen Hebesystem mehrere Reihen von Wälzorganen vorzusehen und in Bezug auf diese auf der entsprechenden Ladefläche mehrere Verschiebeorgane anzuordnen, welche synchron laufen können um die gesamte Last zu bewegen o— der unabhäugig von einander betrieben werden können um nur einen Teil der Ladung zu bewegen . Weiters schließt die Erfindung es nicht aus z.B. auf der selben Ladeflä- ehe mehrere, von einander unabhängige, Hebesmechanismen vorzusehen um so nur einen Teil der Last heben und bewe¬ gen zu können.To achieve this object, the invention proposes to provide several rows of rolling elements on a single lifting system and to arrange several sliding elements with respect to these on the corresponding loading area, which can run synchronously in order to move the entire load or which can be operated independently of one another to move only part of the load. Furthermore, the invention does not rule it out, for example, on the same loading area. before providing several lifting mechanisms that are independent of one another so that only a part of the load can be lifted and moved.

Die Reihen der Wälzorgane sind leerlaufend auf Rahmen gelagert, welche vertikal durch eine oder mehrere Reihen von unter sich verbundenen Hydraulikzylindern vertikal verstellbar sind. In versenkter Stellung der Wälzorgane, also bei auf der Ladeebene aufliegender Ladung, ragen die se nicht über die Ladeebene hinaus , während sie in aus¬ gefahrener Stellung über diese Ebene hinausragen und die Ladung anheben, welche mittels Ketten verschoben werden kann; diese laufen in, in der Ladefläche vorgesehenen, Ril_ len und weisen daraus vorstehende Zähne oder Profile auf. Die Bewegung der Ketten erfolgt in Querrichtung zu den Drehachsen der Wälzorgane. Im Falle von mehreren Ketten ist es möglich diese synchron zu betätigen oder, wenn nur ein Teil der Last verschoben werden soll, diese einzeln zu betätigen.The rows of the rolling elements are idling mounted on frames which are vertically adjustable vertically by one or more rows of interconnected hydraulic cylinders. In the lowered position of the rolling elements, that is to say with the load resting on the loading level, they do not protrude beyond the loading level, while in the extended position they protrude beyond this level and raise the load, which can be shifted by chains; these run in grooves provided in the loading area and have teeth or profiles protruding therefrom. The chains move in the transverse direction to the axes of rotation of the rolling elements. In the case of several chains, it is possible to operate them synchronously or, if only part of the load is to be shifted, to operate them individually.

Die Erfindung wird anhand von einigen vorzuziehenden Aus ührungsbeispielen erfindungsgemäßer Vorrichtungen für das Auf— und Abladen sowie das Verschieben von Behältern oder Waren auf Ladeflächen, welche in der beigelegten Zeichnung schematisch dargestellt sind, näher erklärt; dabei hat die Zeichnung rein erklärende, nicht begrenzende Bedeutung.The invention is explained in more detail by means of some preferred exemplary embodiments of devices according to the invention for loading and unloading as well as moving containers or goods on loading areas, which are shown schematically in the accompanying drawing; the drawing has purely explanatory, not limiting meaning.

Die Fig. 1 zeigt einen Querschnitt durch eine Ladefläche für zwei parallele Ladebereiche mit einer Hebevorrichtung versehen mit zwei Reihen von Hydraulikzylindern.Fig. 1 shows a cross section through a loading area for two parallel loading areas with a lifting device provided with two rows of hydraulic cylinders.

Die Fig. 1a ist eine Draufsicht auf einen Teil der inFig. 1a is a plan view of part of the in

Fig.1 gezeigten Ladefläche.Fig.1 shown loading area.

Die Fig. 2 zeigt einen Querschnitt durch eine Ladeflä- ehe mit zwei unabhängigen, parallelen Hebe- und Verschiebe Vorrichtungen, beide mit einer Reihe von Hydraulikzylin dem .Fig. 2 shows a cross section through a loading area with two independent, parallel lifting and moving Devices, both with a series of hydraulic cylinders.

Die Fig. 3 zeigt einen Querschnitt durch eine Ladefläche mit einer einzigen Hebevorrichtung und einer einzigen Reihe von Hydraulikzylindern.Fig. 3 shows a cross section through a loading area with a single lifting device and a single row of hydraulic cylinders.

Die Fig. 4 zeigt ein Schema betreffend die Ölverteilung für die erfindungsgemäße Vorrichtung.4 shows a diagram relating to the oil distribution for the device according to the invention.

Die Behälter, die Warenstücke oder die Ballen von Waren liegen auf der Ladeebene 1 auf, welche über LängsholmeThe containers, the goods or the bales of goods are on the loading level 1, which over the longitudinal spars

5 mit den Achsen oder der Unterstruktur 7 verbunden ist. An der Ladefläche 1 , in Längsrichtung, zueinander paral¬ lel oder gegebenenfalls in Querrichtung, sind Ausnehmun¬ gen vorgesehen in welchen Lagerschienen 8 für eine Reihe von leerlaufenden Rollen 2 aufgenommen sind. Die Lager¬ schienen 8 mit den Rollen 2 sind vertikal, mittels einer einzigen Verbindungsstruktur 3 (Fig.1), 3b (Fig.3) be¬ weglich oder mittels in Bereiche geteilte Struktur 3a (Fig.2), auf welche eine Reihe von Hydraulikzylinder 4a, 4b wirkt oder zwei Reihen von Hydraulikzylindern 4 wir¬ ken, welche auf der feststehenden Grundstruktur 5, 7 be¬ festigt sind. In versenkter Stellung der Rollen befinden sich diese leicht tiefer als die Ladeebene oder fluchten mit dieser, sodaß die Auflage der Last auf der Ladeflä - ehe gesichert ist (Transportstellung) . Mittels Hydraulik zylinder 4,4a,4b über die vertikal bewegliche 3, 3b Ver¬ bindungsstruktur für die Lagerschienen 8 werden die Rol¬ len 2a aus der Ladeebene ausgefahren wodurch die Last leicht angehoben wird. Diese kann somit auf den Rollen 2 mittels der Ketten 6 verschoben 6c werden, welche in ei¬ genen Rillen, parallel zu den Lagerschienen 8, laufen und aus der Ladeebene 1 vorstehende Zähne 6a oder Profi¬ le aufweisen.5 is connected to the axes or the substructure 7. On the loading area 1, in the longitudinal direction, parallel to one another or possibly in the transverse direction, recesses are provided in which bearing rails 8 for a number of idling rollers 2 are accommodated. The bearing rails 8 with the rollers 2 are movable vertically, by means of a single connecting structure 3 (FIG. 1), 3b (FIG. 3) or by means of structure 3a (FIG. 2) divided into areas, on which a series of Hydraulic cylinder 4a, 4b acts or two rows of hydraulic cylinders 4 act, which are fastened to the fixed basic structure 5, 7. When the rollers are in the lowered position, they are located slightly lower than the loading level or are flush with it so that the load is placed on the loading surface before it is transported (transport position). By means of hydraulic cylinders 4,4a, 4b via the vertically movable 3, 3b connection structure for the bearing rails 8, the rollers 2a are moved out of the loading level, whereby the load is raised slightly. This can thus be moved 6c on the rollers 2 by means of the chains 6c, which run in their own grooves, parallel to the bearing rails 8, and which have teeth 6a or profiles projecting from the loading level 1.

Diese Anordnung der Hebeorgane und der Verschiebeorgane ermöglicht erfindungsgemäß verschiedene praktische Lö¬ sungen wie z.B. die Möglichkeit eine einzige Hebestruktur 3, 8 mittels zwei Reihen von Hydraulikzylindern 4 (Fig.1) zu betätigen, wobei jedoch die Möglichkeit besteht die ge samte Last durch synchrone Betätigung der beiden KettenThis arrangement of the lifting elements and the displacement elements enables various practical solutions according to the invention, for example the possibility of actuating a single lifting structure 3, 8 by means of two rows of hydraulic cylinders 4 (FIG. 1), but it is possible to operate the entire load by synchronously actuating the two chains

--

6 zu bewegen 6c, oder nur eine der Lasthälften zu bewegen 6c indem nur die entsprechende Kette 6 betätigt wird, wäh rend die andere Hälfte der Last nicht verschoben wird, ob wohl sie angehoben ist. Dies ist dadurch möglich, daß parallel zur Ladeflächenlängsachse zwei Reihen von Rollen 2 voneinander unabhängig gelagert sind.6 to move 6c, or to move only one of the load halves 6c by only actuating the corresponding chain 6, while the other half of the load is not being shifted, whether it is raised. This is possible because two rows of rollers 2 are mounted independently of one another parallel to the longitudinal axis of the loading area.

In dem in Fig. 2 gezeigten Beispiel hingegen besteht die Möglichkeit nur einen Teil der Last mittels einer einzi- gen Reihe von Zylindern 4a anzuheben und durch eine oder zwei Ketten 6 zu verschieben .In the example shown in FIG. 2, on the other hand, it is possible to lift only a part of the load by means of a single row of cylinders 4a and to move it by one or two chains 6.

Das in Fig. 3 gezeigte Beispiel zeigt eine Lösung, welche das Anheben der gesamten Last mittels einer einzigen Reihe von Zylindern 4b ermöglicht, während das Verschieben durch zwei synchron laufende Ketten 6 mit Verbindungsprofil 6b erfolgt.The example shown in FIG. 3 shows a solution which enables the entire load to be lifted by means of a single row of cylinders 4b, while the shifting is carried out by two chains 6 running synchronously with connecting profile 6b.

Um die Hebebewegung der Verbindungsstruktur 3, 3a, 3b für die Lagerschienen 8 zu ermöglichen, weisen die Längs_ holme 5 entsprechende Ausnehmungen auf. Bei Fehlen der Last kann die Einziehbewegung der Rollen 2 und der gesam¬ ten beweglichen Struktur 8,3,3a,3b durch Federn erreicht werden, welche zusammen mit dem Gewicht der Struktur das öl aus den Zylindern 4,4a,4b drücken. Diese Federn können z.B. zwischen den Reihen der Zylinder seitlich von diesen oder koachsial zu diesen angebracht werden. Um die verti¬ kale gleichmäßige Hebebewegung 2a der gesamten bewegli - chen Struktur, samt den Wälzorganen, unabhängig von der Verteilung des Gewichtes der Ladung, zu sichern, ist das Volumen des in den einzelnen Verbindungsleitungen 10 zwischen den Zylindern 4 enthalten Öles größer als das Volumen des maximalen Hubraumes eines Zylinders. In order to enable the lifting movement of the connection structure 3, 3a, 3b for the bearing rails 8, the longitudinal bars 5 have corresponding recesses. In the absence of the load, the retracting movement of the rollers 2 and the entire movable structure 8, 3, 3a, 3b can be achieved by springs which, together with the weight of the structure, press the oil out of the cylinders 4, 4a, 4b. These springs can be attached, for example, between the rows of cylinders laterally or coaxially to them. In order to ensure the vertical, uniform lifting movement 2a of the entire movable structure, including the rolling elements, regardless of the distribution of the weight of the load, this is Volume of the oil contained in the individual connecting lines 10 between the cylinders 4 is greater than the volume of the maximum displacement of a cylinder.
