Abstract

A transport container for helium, having an inner container for receiving helium, a thermal shield actively coolable with the aid of a cryogenic liquid and in which the inner container is accommodated, an outer container in which the thermal shield and inner container are accommodated, and a carrying ring provided on the thermal shield. The inner container is suspended from the carrying ring with the aid of first suspension rods, wherein the carrying ring is suspended from the outer container with the aid of second suspension rods, wherein at least one of the first suspension rods has a first spring device and at least one of the second suspension devices has a second spring device in order to ensure a spring pretension of the first suspension rods and the second suspension rods for different heat expansions of the inner container and the thermal shield.

First claim

The invention claimed is:

1. A transport container for helium
an inner container for receiving the helium,
a thermal shield which is actively coolable with the aid of a cryogenic liquid and in which the inner container is accommodated,
an outer container in which the thermal shield and the inner container are accommodated, and
a carrying ring provided on the thermal shield,
wherein the inner container is suspended from the carrying ring with the aid of first suspension rods, and the carrying ring is suspended from the outer container with the aid of second suspension rods,
wherein at least one of the first suspension rods has a first spring device and at least one of the second suspension rods has a second spring device in order to ensure a spring pretension of the first suspension rods and the second suspension rods for different heat expansions of the inner container and the thermal shield.

2. The transport container as claimed in claim 1 , wherein the transport container has a central axis and the first suspension rods are spaced from one another and extend radially inward from the carrying ring toward the central axis and the second suspension rods are spaced from one another and extend radially inward from the outer container toward the central axis.

3. The transport container as claimed in claim 1 , wherein the first spring device and the second spring device each have multiple disk spring elements.

4. The transport container as claimed in claim 1 , wherein in each case four first suspension rods and four second suspension rods are provided.

5. The transport container as claimed in claim 1 , wherein the at least one first suspension rod which has the first spring device is arranged below a center axis of the outer container with respect to a direction of gravitational force.

6. The transport container as claimed in claim 5 , wherein two first suspension rods which each have a first spring device are arranged below the center axis of the outer container with respect to the direction of gravitational force.

7. The transport container as claimed in claim 5 , wherein the at least one second suspension rod which has the second spring device is arranged below the center axis of the outer container with respect to the direction of gravitational force.

8. The transport container as claimed in claim 7 , wherein two second suspension rods which each have a second spring device are arranged below the center axis of the outer container with respect to the direction of gravitational force.

9. The transport container as claimed in claim 1 , wherein the carrying ring has pockets in which the second suspension rods are arranged.

10. The transport container as claimed in claim 1 , wherein the inner container has a fastening flange to which the first suspension rods are fastened.

11. The transport container as claimed in claim 1 , wherein the carrying ring, the first suspension rods and the second suspension rods are assigned to a first cover portion of the inner container.

12. The transport container as claimed in claim 11 , wherein the inner container is suspended at a second cover portion from the thermal shield with the aid of third suspension rods, and wherein the thermal shield is suspended at the second cover portion from the outer container with the aid of fourth suspension rods.

13. The transport container as claimed in claim 12 , wherein the third suspension rods ( 45 , 46 ) and the fourth suspension rods are led through a coolant container in which the cryogenic liquid is accommodated.

14. The transport container as claimed in claim 13 , wherein, at the second cover portion, the inner container is non-displaceable with respect to the thermal shield.

15. The transport container as claimed in claim 1 , wherein the thermal shield completely encloses the inner container.

16. The transport container as claimed in claim 1 , further comprises a coolant container containing cryogenic liquid.

17. The transport container as claimed in claim 5 , wherein first suspension rods arranged above the center axis of the outer container with respect to a direction of gravitational force do not have said first spring devices.

18. The transport container as claimed in claim 7 , wherein the second suspension rods arranged above the center axis of the outer container with respect to a direction of gravitational force do not have said second spring devices.

19. The transport container as claimed in claim 10 , wherein the transport container has a central axis and the first suspension rods each of a first end and a second end, wherein each of the first suspension rods is fastened at the first end to the fastening flange of the inner container and fastened at the second end to the carrying ring, and wherein the each of the first suspension rods extends radially outwardly with respect to the central axis.

20. The transport container as claimed in claim 16 , wherein the outer container has a first cover portion and a second cover portion, the inner container has a first cover portion and a second cover portion, and said thermal shield has a first cover portion and a second cover portion, said coolant container being arranged between said second cover portion of the outer container and said second cover portion of said inner container, and said second cover portion of the thermal shield being arranged between said second cover portion of said inner container and said coolant container.
