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

1 . A transport container ( 1 ) for helium (He), having an inner container ( 6 ) for receiving the helium (He), a thermal shield ( 23 ) which is actively coolable with the aid of a cryogenic liquid (N 2 ) and in which the inner container ( 6 ) is accommodated, an outer container ( 2 ) in which the thermal shield ( 23 ) and the inner container ( 6 ) are accommodated, and a carrying ring ( 29 ) provided on the thermal shield ( 23 ), wherein the inner container ( 6 ) is suspended from the carrying ring ( 29 ) with the aid of first suspension rods ( 30 - 33 ), wherein the carrying ring ( 29 ) is suspended from the outer container ( 2 ) with the aid of second suspension rods ( 34 - 37 ), wherein at least one of the first suspension rods ( 30 - 33 ) has a first spring device ( 38 ) and at least one of the second suspension rods ( 34 - 37 ) has a second spring device ( 43 ) in order to ensure a spring pretension of the first suspension rods ( 30 - 33 ) and the second suspension rods ( 34 - 37 ) for different heat expansions of the inner container ( 6 ) and the thermal shield ( 23 ).

2 . The transport container as claimed in claim 1 , wherein the first suspension rods ( 30 - 33 ) and the second suspension rods ( 34 - 37 ) are in each case arranged in a star shape.

3 . The transport container as claimed in claim 1 , wherein the first spring device ( 38 ) and the second spring device ( 43 ) each have multiple disk spring elements ( 44 ).

4 . The transport container as claimed in claim 1 , wherein in each case four first suspension rods ( 30 - 33 ) and four second suspension rods ( 34 - 37 ) are provided.

5 . The transport container as claimed in claim 1 , wherein the at least one first suspension rod ( 30 - 33 ) which has the first spring device ( 38 ) is arranged below a center axis (M 1 ) of the outer container ( 2 ) with respect to a direction of gravitational force (g).

6 . The transport container as claimed in claim 5 , wherein two first suspension rods ( 32 , 33 ) which each have a first spring device ( 38 ) are arranged below the center axis (M 1 ) of the outer container ( 2 ) with respect to the direction of gravitational force (g).

7 . The transport container as claimed in claim 5 , wherein the at least one second suspension rod ( 34 - 37 ) which has the second spring device ( 43 ) is arranged below the center axis (M 1 ) of the outer container ( 2 ) with respect to the direction of gravitational force (g).

8 . The transport container as claimed in claim 7 , wherein two second suspension rods ( 36 , 37 ) which each have a second spring device ( 43 ) are arranged below the center axis (M 1 ) of the outer container ( 2 ) with respect to the direction of gravitational force (g).

9 . The transport container as claimed in claim 1 , wherein the carrying ring ( 29 ) has pockets ( 39 - 42 ) in which the second suspension rods ( 34 - 37 ) are arranged.

10 . The transport container as claimed in claim 1 , wherein the inner container ( 6 ) has a fastening flange ( 12 ) to which the first suspension rods ( 30 - 33 ) are fastened.

11 . The transport container as claimed in claim 1 , wherein the carrying ring ( 29 ), the first suspension rods ( 30 - 33 ) and the second suspension rods ( 34 - 37 ) are assigned to a first cover portion ( 10 ) of the inner container ( 6 ).

12 . The transport container as claimed in claim 11 , wherein the inner container ( 6 ) is suspended at a second cover portion ( 11 ) from the thermal shield ( 23 ) with the aid of third suspension rods ( 45 , 46 ), and wherein the thermal shield ( 23 ) is suspended from the outer container ( 2 ) with the aid of fourth suspension rods ( 47 , 48 ).

13 . The transport container as claimed in claim 12 , wherein the third suspension rods ( 45 , 46 ) and the fourth suspension rods ( 47 , 48 ) are led through a coolant container ( 16 ) in which the cryogenic liquid (N 2 ) is accommodated.

14 . The transport container as claimed in claim 13 , wherein, at the second cover portion ( 11 ), the inner container ( 6 ) is non-displaceable with respect to the thermal shield ( 23 ).

15 . The transport container as claimed in claim 1 , wherein the thermal shield ( 23 ) completely encloses the inner container ( 6 ).
