Description

Für Transport und Lagerung temperierter Ladegüter sind isolierte Tankcontainer erforderlich, die üblicherweise mit Dämmstoffen isoliert werden, die auf den Tank aufgebracht und von einer Außenhülle umgeben sind. Temperaturänderungen des Ladeguts entstehen zum einen durch das Dämmaterial selbst und zum anderen durch Wärmebrücken, die beispielsweise an den metallischen Verbindungsstellen zwischen Tank und Rahmen entstehen. Diese Temperaturänderungen erfordern zusätzliche Heiz- oder Kühlaggregate, um einen bestimmten Temperaturbereich einzuhalten.Insulated goods are used for the transport and storage of temperature-controlled goods Tank container required, usually insulated with insulation be applied to the tank and surrounded by an outer shell are. Temperature changes of the cargo arise on the one hand from the Insulation material itself and the other through thermal bridges, for example at the metallic connection points between tank and frame arise. These temperature changes require additional heating or Cooling units to maintain a certain temperature range.

Besonders hochwertige Isolierungen, insbesondere Vakuumisolierungen, bei denen der Zwischenraum zwischen dem Tank und der Außenhülle evakuiert ist, können über einen längeren Zeitraum Temperaturbereiche einhalten und damit den Einsatz von Zusatzaggregaten vermeiden. Hier ist die Isolierwirkung entscheidend durch verbleibende Wärmebrücken begrenzt. Insbesondere im Bereich der Tank-Rahmenverbindung ist die Wärmeabgabe oder -aufnahme besonders groß, da die Verbindung zwischen Tank und Rahmen aus Festigkeitsgründen weitgehend über metallische Bauelemente erfolgt.Particularly high quality insulation, especially vacuum insulation, where the space between the tank and the outer shell is evacuated, temperature ranges can occur over a longer period of time comply with and thus avoid the use of additional units. Here is the insulating effect is decisively limited by the remaining thermal bridges. The heat emission is particularly in the area of the tank frame connection especially large because the connection between For reasons of strength, the tank and frame are largely metallic Components are made.

Auch bei einer isolierenden Zwischenlage zwischen tankseitigem Stirnring und rahmenseitigem Sattelring besteht dort über metallische Befestigungsschrauben, die beide Ringe und die Zwischenlage durchsetzen, eine gut leitende, metallische Koppelung zwischen Tank und Rahmen. Eine solche Sattelung ist ebenfalls aus DE 90 14 104 U1 bekannt. Darüber hinaus können herkömmliche Zwischenlagen nur Druckkräfte aufnehmen.The preamble of claim 1 corresponds to a DE 32 12 696 C2 known freight container, in which a tank over a Ring saddle is connected to the front frame. Even with an insulating one Intermediate layer between the tank-side front ring and the frame-side saddle ring exists there via metallic mounting screws, both Insert the rings and the intermediate layer, a well conductive, metallic one Coupling between tank and frame. Such a saddle is also known from DE 90 14 104 U1. In addition, conventional liners only absorb pressure forces.

Der Tankcontainer umfaßt einen im Wesentlichen zylindrischen Tank 1, der über Ringsattelungen 2 mit zwei Stirnrahmen 3 verbunden ist. Jeder Stirnrahmen 3 ist mit zwei oberen und zwei unteren Eckbeschlägen 4, 5 versehen. Die Stirnrahmen 3 weisen obere und untere Querholme 6, 7 sowie Eckstützen 8 auf, die zwischen den Eckbeschlägen 4, 5 angeordnet sind. Zusätzlich sind die Stirnrahmen 3 durch eingesetzte Diagonalstreben 9 verstärkt. The tank container comprises an essentially cylindrical tank 1, which is connected to two end frames 3 via ring saddles 2 . Each end frame 3 is provided with two upper and two lower corner fittings 4, 5 . The end frames 3 have upper and lower cross members 6, 7 and corner supports 8 , which are arranged between the corner fittings 4, 5 . In addition, the end frames 3 are reinforced by inserted diagonal struts 9 .

An der Außenhülle 10 sind zur besseren Kraftübertragung zwischen Außenhülle 10 und Stirnrahmen 3 Sattelstrukturen 11 angebracht, die über Verstrebungen 12 mit den unteren Eckbeschlägen 5 verbunden sind. Zusätzliche Bodengruppen 13 mit Eckbeschlägen 5 erlauben die variable Koppelung an (nicht dargestellte) Fahrzeugchassis.On the outer shell 10 3 saddle structures 11 are attached for better power transmission between the outer shell 10 and the end frame, which are connected via struts 12 to the lower corner fittings 5 . Additional floor groups 13 with corner fittings 5 allow variable coupling to the vehicle chassis (not shown).

Der Stirnrahmen 3 ist an entsprechenden Ausnehmungen in den Querholmen 6, 7, den Eckstützen 8 und den Diagonalstreben 9 mit der Außenhülle 10 verschweißt. Die Stirnrahmen können aber auch entsprechend DE 32 12 696 C2 gestaltet sein und an den Stirnseiten der Enden 14 der Außenhülle 10 angebracht sein.The front frame 3 is welded to the outer shell 10 at corresponding recesses in the cross bars 6, 7, the corner supports 8 and the diagonal struts 9 . The end frames can also be designed according to DE 32 12 696 C2 and attached to the end faces of the ends 14 of the outer shell 10 .

Gemäß der Schnittdarstellung in Figur 3 umfaßt die Ringsattelung 2 einen Stirnring 15, eine Isolierzarge 16 und einen ersten Sattelring 17. Der Stirnring 15 ist als Rohrstück ausgeführt und ist an einem Boden 18 des Tanks 1 angeschweißt. Ein Verstärkungsring 19 mit radial verlaufendem Flansch ist zwischen dem Boden 18 und dem Stirnring 15 eingesetzt. Der erste Sattelring 17 ist mit der zylindrischen Außenhülle 10 verschweißt und über Rippen 20 mit einem zweiten Sattelring 21 verbunden, wobei die Rippen 20 ebenfalls mit der Außenhülle 10 verschweißt sind, die wiederum mit entsprechend ausgeschnittenen Rahmenteilen 6, 7, 8, 9 verschweißt ist. Dabei zeigt Figur 3 das Restprofil einer Eckstütze 8.According to the sectional view in FIG. 3, the ring saddle 2 comprises an end ring 15 , an insulating frame 16 and a first saddle ring 17 . The end ring 15 is designed as a piece of pipe and is welded to a bottom 18 of the tank 1 . A reinforcing ring 19 with a radial flange is inserted between the bottom 18 and the end ring 15 . The first saddle ring 17 is welded to the cylindrical outer shell 10 and connected via ribs 20 to a second saddle ring 21 , the ribs 20 also being welded to the outer shell 10 , which in turn is welded to correspondingly cut out frame parts 6 , 7 , 8 , 9 . 3 shows the remaining profile of a corner support 8 .

Die konische Isolierzarge 16 besteht aus einem metallischen, engen, tankseitigen Anschlußende 22, einem Zwischenstück 23 und einem metallischen, weiten, rahmenseitigen Anschlußende 24. Das Zwischenstück 23 besteht aus einem geeigneten faserverstärkten Kunststoff, in das die Anschlußenden 22, 24 einlaminiert sind, die zusätzlich über das Zwischenstück 23 und die Anschlußenden 22, 24 durchsetzende Stifte 25 formschlüssig fixiert sind. Der Abstand und damit die Anzahl der Stifte 25 kann entsprechend der zu übertragenden Lasten variiert werden. Üblicherweise sind die im unteren Teil des Tankcontainers übertragenen Lasten höher als die im oberen Teil. Damit sollte im unteren Teil die Anzahl der Stifte 25 erhöht werden.The conical insulating frame 16 consists of a metallic, narrow, tank-side connection end 22 , an intermediate piece 23 and a metallic, wide, frame-side connection end 24 . The intermediate piece 23 consists of a suitable fiber-reinforced plastic, into which the connecting ends 22, 24 are laminated, which are additionally positively fixed via the intermediate piece 23 and the connecting ends 22, 24 through pins 25 . The distance and thus the number of pins 25 can be varied according to the loads to be transferred. The loads transmitted in the lower part of the tank container are usually higher than those in the upper part. This should increase the number of pins 25 in the lower part.

Der Querschnitt des Zwischenstücks 23 kann zwischen den beiden Anschlußenden 22, 24 reduziert werden, um die Wärmeübertragung weiter zu verringern. Zusätzlich kann innerhalb des Zwischenstücks zwischen den Anschlußenden eine Zwischenlage 26 mit zusätzlich verringerter Wärmeleitfähigkeit eingesetzt werden, um die Isolierwirkung des Zwischenstücks 23 noch weiter zu verbessern.The cross section of the intermediate piece 23 can be reduced between the two connection ends 22, 24 in order to further reduce the heat transfer. In addition, an intermediate layer 26 with an additionally reduced thermal conductivity can be used within the intermediate piece between the connection ends in order to further improve the insulating effect of the intermediate piece 23.

Das tankseitige Anschlußende 22 ist mit der zylindrischen Umfangsfläche 28 des Stirnrings 15 verschweißt, und das rahmenseitige Anschlußende 24 ist mit der radial verlaufenden Stirnfläche 29 des ersten Sattelrings 17 verschweißt. Mit dieser Anordnung lassen sich bei der Montage Längsund Quertoleranzen bezüglich der Tankachse 30 ausgleichen. An der radialen Stirnfläche 29 ist ebenfalls das Ende 14 der Außenhülle 10 angeschweißt. Damit entsteht zwischen Tank 1 und Außenhülle 10 ein evakuierbarer Hohlraum 27. The tank-side connection end 22 is welded to the cylindrical peripheral surface 28 of the end ring 15 , and the frame-side connection end 24 is welded to the radially extending end surface 29 of the first saddle ring 17 . With this arrangement, longitudinal and transverse tolerances with respect to the tank axis 30 can be compensated for during assembly. The end 14 of the outer shell 10 is also welded to the radial end face 29 . This creates an evacuable cavity 27 between the tank 1 and the outer casing 10 .

Der faserverstärkte Kunststoff, aus dem das Zwischenstücks 23 besteht, weist niedrige Ausgasungsraten auf, um die innere Leckage des evakuierten Hohlraums 27 gering zuhalten. Vorteilhaft ist ein anfängliches Ausgasungsvolumen von weniger als 9x1012 mol/cm3 innerhalb von 2 Monaten bei einem anfänglichen Umgebungsdruck von 10-4 hPa. Die Zugfestigkeit einer geeigneten Isolierzarge 16 liegt über 105 N/mm2.The fiber-reinforced plastic from which the intermediate piece 23 is made has low outgassing rates in order to keep the internal leakage of the evacuated cavity 27 low. An initial outgassing volume of less than 9x10 12 mol / cm 3 is advantageous within 2 months at an initial ambient pressure of 10 -4 hPa. The tensile strength of a suitable insulating frame 16 is over 105 N / mm 2 .

Die Außenhülle 10 weist zwei Kompensatorringe 31 auf, die temperaturbedingte unterschiedliche Längenänderungen in axialer Richtung von Tank 1 und Außenhülle 10 durch elastische Verformung ausgleichen. Zwischen den Kompensatorringen 31 ist ein Anschlußbereich 32 angeordnet, der die Außenhülle 10 durchsetzt und mit dem Tank 1 verbunden ist. Durch die Kompensatorringe 31 bleiben die Verbindungsstellen zwischen Anschlußbereich 32 und Außenhülle 10 einerseits und zwischen Anschlußbereich 32 und Tank 1 andererseits spannungsarm. The outer shell 10 has two compensator rings 31 , which compensate for temperature-related different length changes in the axial direction of the tank 1 and outer shell 10 by elastic deformation. Between the compensator rings 31 there is a connection area 32 which passes through the outer casing 10 and is connected to the tank 1 . Due to the compensator rings 31 , the connection points between the connection area 32 and the outer casing 10 on the one hand and between the connection area 32 and the tank 1 on the other hand remain low in tension.
