Claims (11)

delete delete A storage tank in which a cryogenic liquefied gas is stored; And
And a support device for fixing and supporting the storage tank and for absorbing heat shrinkage and deformation due to thermal expansion of the storage tank,
The support device comprises:
A plurality of support blocks for holding and supporting the storage tank; And
And a table member that supports the support block and is capable of absorbing heat shrinkage and deformation due to thermal expansion of the storage tank while adjusting a distance between the support blocks,
The support block includes:
A fixed support block having one side fixed to the bottom surface of the outer surface of the storage tank and the other side fixed to the table member; And
And a movable support block having one side fixed to the bottom surface of the outer surface of the storage tank and the other side slidably coupled to the table member,
Wherein the table member comprises:
A table main body installed apart from the bottom surface of the storage tank and covering the entire area including the bottom surface of the storage tank; And
And a rim dam disposed on a rim of the table main body and protruding upward from the table main body for temporarily storing liquefied gas leaked from the storage tank,
Wherein the table member is provided movably on a transfer rail by a wheel provided at a lower portion thereof.
The method of claim 3,
Wherein the fixed support block is disposed at the center of the lower surface of the storage tank,
Wherein at least three said movable support blocks are radially disposed about said fixed support block and slidably engaged on said table member.
The method of claim 3,
Wherein the fixed support block is provided at a rim of the table member,
Wherein at least two of the movable support blocks are slidably installed on a rim of the table member at an angle with respect to the fixed support block.
The method of claim 3,
And a slider installed between the movable support block and the table member for sliding the movable support block on the table member,
The slider
Wherein the movable support block is moved on the slider rail formed in the direction of the movable support block in the fixed support block and is slidably coupled to the table member via a support bearing or a support roller.
The apparatus as claimed in claim 3,
And the height of the support block is adjustable so that the storage tank fixed on the upper side is moved up and down.
8. The apparatus of claim 7,
An upper support block having downward inclined surfaces formed at both ends in the center direction;
A pair of split lower support blocks supporting a lower side of the upper support block and having support slopes opposed to the downward slopes; And
And height adjusting means for adjusting the height of the upper support block by adjusting a gap between the pair of lower support blocks.
[10] The apparatus of claim 8,
A first lower block provided to support a first downward sloping surface of the upper support block;
And a second lower block provided to support a second downward sloping surface of the upper support block,
Wherein the height adjusting means comprises:
A first slide bar having one side fixed to the first lower block and the other slide slidably installed on the second lower block and having a first fixed gear;
A second slide bar having one side fixed to the second lower block and the other side slidably installed on the first lower block and having a second fixed gear; And
A first fixed gear and a second fixed gear which are meshed with the first fixed block and the second fixed block so as to adjust a distance between the first bottom block and the second bottom block, And a gear.
