Definitions

  • the invention relates to a device for storing the inner container of a vacuum-insulated cylindrical transport container for low-boiling liquefied gases in the outer container.
  • the bearing elements should be as light as possible and designed so that the inner container can have the largest possible diameter. This is intended to keep the share of the payload in the permissible container r total weight a as large as possible. After all, the bearing elements should be poor thermal bridges so that they do not impair the vacuum insulation too much. This should keep evaporation losses low.
  • the national and international transport regulations for dangerous goods further limit the possibilities of the designer.
  • the inner container storage must be designed so that twice the total weight in the direction of travel and in the vertical direction down and the single total weight is taken up and horizontally laterally.
  • An additional restrictive condition is that the shape of the bottoms and the cylindrical shape of the outer container must not be interrupted, since such interruptions reduce the payload disproportionately.
  • Another limitation is given by the manufacturing costs, which preclude technically complex inner container bearings from the outset.
  • the invention has for its object to provide an inner container storage within the framework of the conditions mentioned, with which large payloads can be realized and the manufacturing costs can be reduced.
  • the trapezoidal transverse segments of the fixed bearing form a shear-resistant connection between the inner and outer container, which expands towards the outer container in accordance with the torque curve, so that the longitudinal forces can be absorbed in the direction of travel. Since these longitudinal forces do not have to be absorbed by the floating bearing, the transverse segments there preferably have the shape of a rectangle in order to save weight.
  • a T-shaped reinforcing ring is preferably also arranged on the inner surface of the inner container in the area of the fixed bearing and the floating bearing. Ropes which are in the area of fixed bearings and are preferred as elastic mounts Non-locating bearings are guided over the inner container and fastened in abutments that are on the inner surface of the outer; container are arranged.
  • An important advantage of the invention is that the distance in the area of the inner container storage between the inner and outer container can be considerably reduced compared to previous designs without reducing the thermal insulation and the stability. This results in a considerable increase in the payload.
  • the design of the fixed and floating bearings is also so simple that the manufacturing costs are reduced significantly.
  • the vacuum-insulated transport container shown in FIG. 1 consists of the inner container 1 and the outer container 2.
  • the undercarriage and the fastening of the outer container on the undercarriage are not shown.
  • a vacuum is maintained between the inner container 1 and the outer container 2 for insulation.
  • the storage of the inner container 1 in the outer container 2 is carried out by a fixed bearing 3, a floating bearing 4 and ropes 5. Die
  • Ropes 5 are attached to abutments 6, which are arranged on the outer container 2.
  • the fixed bearing 3 consists of a rigid sheet metal construction with a meandering cross section parallel to the circumference of the transport container.
  • This rigid sheet metal construction consists essentially of transverse segments 7 arranged in the longitudinal direction of the transport container and segments 8 running in the circumferential direction.
  • Another part of the fixed bearing 3 is the bearing shell 9, which is fastened on the support ring 10, which is welded onto the inner container 1.
  • a corresponding support ring 11 is provided on the outer container 2.
  • the floating bearing 4 is also designed according to the invention as a rigid sheet metal construction. In principle, it corresponds to the fixed bearing 3, that is to say essentially consists of transverse segments 12 and segments 13. Furthermore, support rings 14 and 15 are provided on the inner and outer container. The connection to the inner container 1 is made via a bearing shell 16, which, in contrast to the fixed bearing 3, is not rigid with the inner container 1 is connected. The inner container 1 therefore slides by means of the support ring 14 on the bearing ; shell 16. The floating bearing 4 is therefore not claimed by temperature-related changes in length of the inner container 1. Since stresses on the floating bearing 4 in longitudinal!
  • a reinforcing ring 17 with a T-shaped cross section is provided in the area of the floating bearing 4.
  • a corresponding reinforcement ring is also located in the area of the fixed bearing 3, but is not shown in the drawing.
  • the upward forces are absorbed by ropes 5.
  • Fig. 7 shows the attachment of the ropes 5 to the outer container in detail.
  • the ropes 5 are guided over the inner container 1 and attached to abutments 6.
  • the attachment and bracing is carried out by screw connections 18.
  • the abutments 6 are welded to the inside of the outer container 2.
  • the abutments 6 are reinforced by stiffening plates 19 and 20.
  • the invention makes it possible to maintain the distance between the inner and outer containers of approximately 150 mm in the area of the inner container storage in the case of a road transport container of customary size. This means a high proportion of the payload in the permissible total container weight.
  • the heat-conducting cross section from the inner to the outer container is kept so small that the thermal insulation corresponds to the current state of the art.
  • the shrinkage of the inner container in diameter when the temperature changes from the assembled state to the operating state is taken into account by appropriate pretensioning of the ropes 5, so that the ropes are tension-free in the operating state.
  • the payload was increased by approx. 500 kg. Since the rigid construction of the saddle bearings is relatively simple, it also saved around 200 hours in production.
