    • Special transport containers which are designed with double walls and which have an outer container with a cylindrical main body and two end walls in which a similarly designed inner container is accommodated are used for the transportation of cryogenic fluids. A holder is arranged at each end of the inner container. The first holder is designed to be rigid and is connected to the adjacent end wall of the outer container. The second holder has two holding parts by means of which the two end walls can be displaced relative to one another in the axial direction. The one movable holding part is formed by a cylindrical spigot which is retained by a hollow cylindrical profile element. Since the spigot shrinks, even in diameter, because of the low temperature of the inner container, the surfaces in mutual contact practically reduce to a very narrow section of the circumferential surfaces. This results in a very high surface contact pressure and high wear on the surfaces in contact because of the horizontal accelerations occurring during transport. This problem is solved in that the first holding part (31) of the movable holder (22) has two flat contact surfaces (33; 34) which interact with two flat bearing surfaces (36; 37) of the second holding part (32), which bearing surfaces are arranged in a V-shape and are aligned symmetrically to the vertical plane (35) of the longitudinal axis (19). Even when the second holding part (32) shrinks, the surfaces in contact retain their flat form, and thereby a low surface contact pressure and low wear is ensured.
    • 设计有双壁的特殊运输集装箱,其具有带有圆筒形主体的外部容器和容纳类似设计的内部容器的两个端壁用于运输低温流体。 在内容器的每个端部设置有保持器。 第一保持器被设计成刚性并且连接到外部容器的相邻端壁。 第二保持器具有两个固定部分,两个端壁可以在轴向上相对于彼此移位。 一个可移动保持部分由圆柱形插口形成,圆柱形插口由中空圆柱形轮廓元件保持。 由于插管甚至在直径方面收缩,由于内部容器的低温,相互接触的表面实际上减小到圆周表面的非常窄的部分。 这导致非常高的表面接触压力和在接触表面上的高磨损,因为在运输期间发生水平加速度。 这个问题的解决之处在于,可移动保持器(22)的第一保持部分(31)具有与第二保持部分(32)的两个平坦的支承表面(36; 37)相互作用的两个平坦接触表面(33; 34) 所述轴承表面布置成V形并且对称地对准所述纵向轴线(19)的垂直平面(35)。 即使当第二保持部(32)收缩时,接触面保持其扁平形状,从而确保了低的表面接触压力和低的磨损。
