Abstract
The invention provides a support apparatus for a large vacuum heat-insulation liquid hydrogen storage tank. The support apparatus comprises a storage tank, a fixing device, two spacing anti-rotation devices and four vertical support bearing devices, wherein the fixing device is arranged on the upper portion of the storage tank; the two spacing anti-rotation devices are arranged on the lower portion of the storage tank; and the four vertical support bearing devices are arranged at two sides of the lower portion of the storage tank. The support apparatus can bear the weight loads of an inner container and a medium contained in the inner container, and can freely shrink when the work temperature of the inner cavity changes, so the generation of constraint loads is avoided. When the work temperature of the inner container changes, the fixing device is adopted as a basic point, the inner container can freely elongate or shorten, and simultaneously the fixing device also can bear an axial shock load. The vertical bearing devices deflect rightward or leftward through a spherical hinge structure via treating the lower portions as support points to adapt to the telescoping change of the tank body length. The anti-rotation devices can axially telescope, can bear the transverse shock of the storage tank, and circumferentially fix the inner container.

Summary of the invention
The objective of the invention is to be no more than 100m in order to solve existing liquid hydrogen tank capacity
3, boundary dimension and weight is all less, the supporting way that adopt crossbars or end socket suspention are not suitable for the problem of large-scale liquid hydrogen tank, and then the support device of the adiabatic liquid hydrogen tank of a kind of large-scale vacuum are provided more between the interior outer tank.
The objective of the invention is to be achieved through the following technical solutions:
The present invention includes: basin, a fixing device, two spacing device for preventing rotation and four vertical support bearings, a described fixing device is arranged on the top of basin, described two spacing device for preventing rotation are arranged on the bottom of basin, and described four vertical support bearings are arranged on the both sides of basin bottom.
Advantage of the present invention is: can bear the weight load of inner container and splendid attire medium, again can be when the inner container operating temperature changes free shrink, avoid the generation of restraint forces.Take fixing device as basic point, inner container freely elongates or shortens when the inner container temperature changes, and fixing device can also be born axial impact loading simultaneously.The inner container support post take the bottom as strong point generation deflection, to adapt to the telescopic variation of cylindrical shell length by spherical hinge structure.The cylindrical shell device for preventing rotation both can axial stretching, can bear the basin side knock again, circumferentially the immobilized substance device.
