Two outer corner fittings (17) are provided on the underside of the two ends of the cross member (15); inner corner fittings (28) are also provided on the underside of each longitudinal spar (16) at the point at which it is connected to the outer reinforcing ring (13). Seen in the longitudinal direction of the tank, the two outer corner fittings (17) are at a mutual distance of 30 '(approx. 9125 mm) and the inner corner fittings (28) are at a distance of 20' (approx. 6058 mm).

Description

Die Erfindung betrifft einen Transporttank, insbesondere einen sogenannten Wechseltank. Unter Wechseltanks werden um­setzbare, tankcontainerähnliche Transporttanks verstanden, die überwiegend im kombinierten oder multimodalen Transport von Flüssigkeiten, Schüttgut und Gasen im Straßen- und Schienen­verkehr eingesetzt werden.The invention relates to a transport tank, in particular a so-called swap tank. Interchangeable tanks are transportable, tank-container-like transport tanks that are mainly used in the combined or multimodal transport of liquids, bulk goods and gases in road and rail traffic.

Ein Transporttank mit den im ersten Teil des Anspruchs 1 angegebenen Merkmalen ist aus DE 84 09 021 U1 bekannt. Dort handelt es sich um einen voll stapelfähigen ISO-Tankcontainer, bei dem der bei noch älteren Bauformen vorhandene, den Tank vollständig umgebende Außenrahmen auf zwei Stirngruppen be­schränkt ist, deren jede vier Eckbeschläge aufweist und über vier Sattelstücke und einen Stirnring mit dem betreffenden nach außen gewölbten Stirnboden des eigentlichen Tanks verbun­den ist.A transport tank with the features specified in the first part of claim 1 is known from DE 84 09 021 U1. There it is a fully stackable ISO tank container, in which the outer frame, which is present in even older designs and completely surrounds the tank, is limited to two end groups, each of which has four corner fittings and has four saddle pieces and a front ring with the relevant bulging outwards Front end of the actual tank is connected.

Der Erfindung liegt die Aufgabe zugrunde, einen Wechsel­tank zu schaffen, der einerseits ein noch geringeres Tarage­wicht aufweist, andererseits eine sichere Einleitung aller am Tank angreifenden Kräfte in die unteren Eckbeschläge einer Rahmenstruktur gewährleistet und gleichzeitig eine wahlweise Verriegelung an in unterschiedlichen Abständen auf dem jewei­ligen Fahrzeug vorhandenen Drehschlössern oder sonstigen Arre­tierungselementen gestattet.The invention has for its object to provide a swap tank which on the one hand has an even lower tare weight, on the other hand ensures a secure introduction of all forces acting on the tank into the lower corner fittings of a frame structure and at the same time an optional locking to existing at different distances on the respective vehicle Rotary locks or other locking elements allowed.

Die Lösung dieser Aufgabe ist im Anspruch 1 gekennzeich­net. Danach ist die Rahmenstruktur auf lediglich die beiden unteren Stirnbereiche des Transporttanks reduziert, wobei je­der dieser beiden Rahmenteile aus einem unteren Querholm und zwei über nur einen Teil der Tanklänge verlaufenden unteren Längsholmen besteht. Die Verbindung zwischen den Tankböden und den betreffenden Rahmenteilen erfolgt über ein Stirnringele­ment, das über einen Bereich von nur 90° bis 180° der unteren Tankbodenhälfte verläuft und über zwei dreieckige Sattelstücke mit dem betreffenden Querholm verbunden ist. Weiter innen sind die Längsholme an einem den zylindrischen Tank-Hauptteil umge­benden Verstärkungsring befestigt.The solution to this problem is characterized in claim 1. Thereafter, the frame structure is reduced to only the two lower end regions of the transport tank, each of these two frame parts consisting of a lower cross member and two lower longitudinal members extending over only part of the tank length. The connection between the tank bottoms and the relevant frame parts takes place via a front ring element which extends over a range of only 90 ° to 180 ° of the lower one Half of the tank floor runs and is connected to the relevant cross member via two triangular saddle pieces. Further inside, the longitudinal bars are attached to a reinforcement ring surrounding the cylindrical main part of the tank.

Diese Struktur ergibt eine auf praktisch ein Minimum an Bauteilen und Ausmaßen begrenzte Stirn- und Längssattelung, die zur Aufnahme der am Tank angreifenden Kräfte ausreicht. Gleichzeitig bieten sich an den äußeren Eckpunkten von Quer- und Längsholmen sowie an den Stellen, an denen die Längsholme mit den Verstärkungsringen verbunden sind, Befestigungspunkte für äußere und innere Eckbeschläge. Der erfindungsgemäße Transporttank weist somit insgesamt acht untere Eckbeschläge auf, deren gegenseitiger Abstand in Tanklängsrichtung entspre­chend zwei unterschiedlichen, auf Fahrzeugen üblichen Verrie­gelungsmaßen gewählt sind. In der vorteilhaften Ausgestaltung der Erfindung nach Anspruch 8 beträgt der Abstand zwischen den äußeren Eckbeschlägen 30' (ca. 9125 mm) und der der inneren Eckbeschläge 20' (ca. 6058 mm).This structure results in a frontal and longitudinal saddle limited to practically a minimum of components and dimensions, which is sufficient to absorb the forces acting on the tank. At the same time, there are fastening points for outer and inner corner fittings at the outer corner points of cross and longitudinal spars and at the points where the longitudinal spars are connected to the reinforcement rings. The transport tank according to the invention thus has a total of eight lower corner fittings, the mutual spacing of which in the longitudinal direction of the tank is selected in accordance with two different locking dimensions which are customary on vehicles. In the advantageous embodiment of the invention according to claim 8, the distance between the outer corner fittings 30 '(approx. 9125 mm) and that of the inner corner fittings 20' (approx. 6058 mm).

Zusätzliche Versteifungsmaßnahmen für die Sattel- und Rahmenstrukturen sind in den Unteransprüchen 2, 3 und 5 ange­geben. Die Maßnahme des Anspruchs 4 dient zur Vermeidung von Spannungsspitzen an den Enden der Stirnringelemente. In der Weiterbildung der Erfindung nach den Ansprüchen 6 und 7 werden die Längsholme gleichzeitig als Greifkanten unter weiterer Abstützung am Tank herangezogen.Additional stiffening measures for the saddle and frame structures are specified in subclaims 2, 3 and 5. The measure of claim 4 serves to avoid voltage peaks at the ends of the end ring elements. In the development of the invention according to claims 6 and 7, the longitudinal spars are simultaneously used as gripping edges with further support on the tank.

Ein bevorzugtes Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert, in der

  • Figur 1 eine teilweise Seitenansicht und
  • Figur 2 eine Stirnansicht eines Transporttanks zeigt.
A preferred embodiment of the invention is explained in more detail with reference to the drawing in which
  • Figure 1 is a partial side view
  • Figure 2 shows an end view of a transport tank.

Gemäß der Zeichnung besteht der Tank 10 aus einem kreis­zylindrischen Hauptteil 11 mit gewölbten Stirnböden 12, von denen in Figur 1 nur einer zu sehen ist. Der Hauptteil 11 ist von mehreren Verstärkungsringen 13, 14 umgeben. Figur 1 zeigt nur den rechten Teil des Tanks 10, dessen vertikale Mittelebe­ne weiter links vom Verstärkungsring 14 liegt und daher nicht mehr in der Zeichnung erscheint.According to the drawing, the tank 10 consists of a circular cylindrical main part 11 with curved end bottoms 12, of which only one can be seen in FIG. 1. The main part 11 is surrounded by a plurality of reinforcing rings 13, 14. Figure 1 shows only the right part of the tank 10, the vertical center plane of which is further to the left of the reinforcement ring 14 and therefore no longer appears in the drawing.

In dem in Figur 1 gezeigten Endbereich wird der Tank 10 von einem Rahmenteil aufgenommen, der aus einem Querholm 15 und zwei Längsholmen 16 besteht. An den beiden äußeren Ecken des Querholms 15 ist an dessen Unterseite jeweils ein äußerer Eckbeschlag 17 angeschweißt.In the end region shown in FIG. 1, the tank 10 is received by a frame part, which consists of a cross member 15 and two longitudinal spars 16. An outer corner fitting 17 is welded to the underside of the two outer corners of the cross member 15.

Am Stirnboden 12 ist ein Stirnringelement 18 mit L-Profil angeordnet, dessen parallel zu Tanklängsachse 19 verlaufender Flansch 20 in dem die stärkste Krümmung aufweisenden Krempen­bereich des Stirnbodens oder in dem weniger gekrümmten Bereich des innerhalb des Krempenbereichs an den Stirnboden 12 ange­schweißt ist. Das Stirnringelement 18 verläuft über einen Winkel von 135° und ist zur vertikalen Längsmittelebene symme­trisch angeordnet. Die beiden Enden des Flansches 20 sind zur Vermeidung von Spannungsspitzen an die Mantelfläche von radial auf den Stirnboden 12 aufgesetzten Rohrabschnitten 21 ange­schweißt, die zum weiteren Spannungsabbau nach außen einen Gehrungsschnitt aufweisen. Anstelle des genannten L-Profils kann das Stirnringelement 18 auch ein T-Profil aufweisen und mit dem Steg am Stirnboden 12 ansetzen. In jedem Fall weist das Stirnringelement einen in Radialrichtung weisenden Flansch 22 auf.On the front base 12 there is an end ring element 18 with an L-profile, the flange 20 of which extends parallel to the longitudinal axis 19 of the tank and is welded to the front base 12 in the brim area of the front base with the greatest curvature or in the less curved area within the brim area. The end ring element 18 extends over an angle of 135 ° and is arranged symmetrically to the vertical longitudinal center plane. To avoid stress peaks, the two ends of the flange 20 are welded to the outer surface of pipe sections 21 which are placed radially on the end face 12 and which have a miter cut for further stress relief to the outside. Instead of the L-profile mentioned, the front ring element 18 can also have a T-profile and attach to the web on the front base 12. In any case, the end ring element has a flange 22 pointing in the radial direction.

Auf den Querholm 15 sind zwei dreieckige Sattelstücke 23 aufgesetzt, wobei jeweils das senkrecht zur Tanklängsachse 19 stehende Flächenteil 24 am radialen Flansch 22 des Stirnring­elements 18 anliegt. An der unteren Kante des Flächenteils 24 ist ein horizontaler Flansch 25 angekantet, der auf der oberen Fläche des Querholms 15 aufliegt. An die bezüglich des Tanks äußere schräge Kante des Flächenteils 24 ist ein Verstärkungs­flansch 26 angekantet, der dreieckig oder trapezförmig mit einer langen unteren, mit dem Flansch 25 verbundenen Kante geformt ist. Die dritte innere Kante des Flächenteils 24 ver­läuft tangential zum Stirnboden 12 und reicht möglichst weit an diesen heran, um eine möglichst große Überschneidungsfläche zwischen dem Flächenteil 24 und dem Flansch 22 des Stirnring­elements 18 zu gewinnen.Two triangular saddle pieces 23 are placed on the cross member 15, the surface part 24, which is perpendicular to the tank longitudinal axis 19, abutting against the radial flange 22 of the end ring element 18. At the lower edge of the surface part 24, a horizontal flange 25 is folded, which rests on the upper surface of the cross member 15. A reinforcing flange 26, which is triangular or trapezoidal in shape with a long lower edge connected to the flange 25, is edged to the oblique edge of the surface part 24 with respect to the tank. The third inner edge of the surface part 24 extends tangentially to the end face 12 and extends as far as possible to this in order to obtain the largest possible overlap area between the surface part 24 and the flange 22 of the end ring element 18.

Die beschriebene Gestaltung des Stirnringelements 18 und des Sattelstücks 23 ermöglicht es, bei der Montage die beiden Rahmenteile derart anzuordnen, daß die äußeren Eckbeschläge 17 in Tanklängsrichtung den vorgeschriebenen Norm-Abstand aufwei­sen, daraufhin die Sattelstücke 23 so weit in Tanklängsrich­ tung zu verschieben, bis die Flächenteile 24 am Flansch 22 des bereits vorher an den Stirnboden 12 des Tanks 10 angeschweiß­ten Stirnringelements 18 anstoßen, und in diesem Zustand die Sattelstücke 23 mit dem Stirnringelement 18 und dem Querholm 15 zu verschweißen oder zu verschrauben. Dadurch lassen sich bei der Fertigung der einzelnen Bauteile, insbesondere des Tanks 10 selbst, und beim Anschweißen der Stirnringelemente 18 an die Stirnböden 12 unvermeidbare Toleranzen ausgleichen.The described design of the end ring element 18 and the saddle piece 23 makes it possible to arrange the two frame parts during assembly in such a way that the outer corner fittings 17 have the prescribed standard distance in the longitudinal direction of the tank, then the saddle pieces 23 so far in the longitudinal direction of the tank device to move until the surface parts 24 on the flange 22 of the previously welded to the end face 12 of the tank 10 butt ring element 18, and in this state the saddle pieces 23 with the end ring element 18 and the cross member 15 to weld or screw. This makes it possible to compensate for unavoidable tolerances in the manufacture of the individual components, in particular the tank 10 itself, and when the end ring elements 18 are welded to the end plates 12.

Die dreieckige Form der Sattelstücke 23 ist nicht nur vom Gesichtspunkt der Material- und Gewichtsersparnis günstig, sondern entspricht auch der Richtung der vom Tank 10 unmittel­bar in die Eckbeschläge 17 einzuleitenden Kräfte.The triangular shape of the saddle pieces 23 is not only favorable from the point of view of saving material and weight, but also corresponds to the direction of the forces to be introduced by the tank 10 directly into the corner fittings 17.

Zwischen den beiden dreieckigen Sattelstücken 23 kann zur weiteren Abstützung bei Bedarf ein rechteckiges Knotenblech 27 vorgesehen sein, das mit einer senkrecht stehenden Fläche am radial verlaufenden Flansch 22 des Stirnringelements 18 und mit einem an seiner unteren Seite angekanteten Flansch an die obere Fläche des Querholms 15 angeschweißt oder angeschraubt ist.For further support, a rectangular gusset plate 27 can be provided between the two triangular saddle pieces 23, which is welded to the upper surface of the cross member 15 with a vertical surface on the radially extending flange 22 of the end ring element 18 and with a flange bent on its lower side or screwed on.

Die Längsholme 16 stoßen mit ihren inneren Enden am Ver­stärkungsring 14 an und sind an einer Zwischenstelle am Ver­stärkungsring 13 befestigt. An der Befestigungsstelle mit dem Verstärkungsring 13 ist an der Unterseite jedes Längsholms 16 ein innerer Eckbeschlag 28 angebracht.The longitudinal bars 16 abut with their inner ends on the reinforcement ring 14 and are fastened to the reinforcement ring 13 at an intermediate point. At the attachment point with the reinforcement ring 13, an inner corner fitting 28 is attached to the underside of each longitudinal spar 16.

Vorzugsweise beträgt der Abstand a zwischen dem in Figur 1 gezeigten inneren Eckbeschlag 28 und dem symmetrisch dazu am anderen Ende des Tanks 10 vorgesehenen (nicht gezeigten) inne­ren Eckbeschlag 20' (ca. 6058 mm). Ferner beträgt der Abstand zwischen dem inneren Eckbeschlag 28 und dem äußeren Eckbe­schlag 17 vorzugsweise 5' (ca. 1534 mm), woraus sich zwischen dem in Figur 1 gezeigten äußeren Eckbeschlag 17 und dem auf der gleichen Tankseite symmetrisch dazu liegenden (nicht ge­zeigten) äußeren Eckbeschlag ein Abstand b von 30' (ca. 9125 mm) ergibt. Diese Abstandsmaße sind deshalb zweckmäßig, weil an für ISO-Container gebauten Containerfahrzeugen Drehschlös­ser oder sonstige Arretierungselemente üblicherweise in einem dieser Abstände angeordnet sind. Der gezeigte Transporttank läßt sich somit sowohl mit solchen Fahrzeugen transportieren, die für 20'-Container bestimmt sind, als auch mit solchen, die für 30'-Container ausgelegt sind.The distance a between the inner corner fitting 28 shown in FIG. 1 and the inner corner fitting 20 '(not shown) provided symmetrically at the other end of the tank 10 is preferably approximately 6058 mm. Furthermore, the distance between the inner corner fitting 28 and the outer corner fitting 17 is preferably 5 '(approx. 1534 mm), from which there is between the outer corner fitting 17 shown in FIG. 1 and the outer corner fitting (not shown) which is symmetrical to it on the same tank side a distance b of 30 '(approx. 9125 mm) results. These spacing dimensions are expedient because rotary locks or other locking elements are usually arranged at one of these spacings on container vehicles built for ISO containers. The transport tank shown can thus be transported with such vehicles, which are intended for 20 'containers as well as those which are designed for 30' containers.

Im Bereich zwischen den beiden Verstärkungsringen 13, 14 dient der Längsholm 16 als Greifkante. In diesem Bereich setzt an den Längsholm 16 ein Blechstück 29 an, dessen an die obere Kante des Längsholms 16 angrenzendes vertikales Flächenteil 30 die Funktion der über der Greifkante geforderten Gleitfläche erfüllt. An das Flächenteil 30 ist ein radial verlaufendes Flächenteil 31 angekantet, das mit dem nach außen weisenden Steg einer an den Mantel des Tanks 10 zwischen den beiden Ver­stärkungsringen 13, 14 angeschweißten T-Profil-Auflageschiene 32 verbunden ist.In the area between the two reinforcement rings 13, 14, the longitudinal bar 16 serves as a gripping edge. In this area, a piece of sheet metal 29 is attached to the longitudinal spar 16, the vertical surface part 30 of which adjoins the upper edge of the longitudinal spar 16 and fulfills the function of the sliding surface required above the gripping edge. On the surface part 30 is a radially extending surface part 31 which is connected to the outwardly pointing web of a T-profile support rail 32 welded to the jacket of the tank 10 between the two reinforcing rings 13, 14.

Wie in Figur 1 und 2 gezeigt, können die äußeren und die inneren Eckbeschläge 17, 28 bei Bedarf jeweils über schräge Konsolen 33 gegenüber dem Längsholm 16 und dem Querholm 15 zu­sätzlich abgestützt sein. Die Quer- und Längsholme können aus geschlossenem Vierkantrohr, stehendem I-Träger oder nach innen oder außen offenem, hochkant stehenden U-Profil in warmgewalz­ter Normalausführung gefertigt sein.As shown in FIGS. 1 and 2, the outer and the inner corner fittings 17, 28 can be additionally supported, if necessary, in each case via oblique brackets 33 with respect to the longitudinal spar 16 and the transverse spar 15. The cross and longitudinal spars can be made from a closed square tube, a standing I-beam or an upright standing U-profile open to the inside or outside in a hot-rolled standard version.
