Underground LNG storage tank belongs to liquefied natural gas transmission & distribution technology field.
Background technique
Secure storage is the key link in liquefied natural gas (LNG) industrial chain.LNG storage tank is that LNG receives system
Core memory facility, investment is big, and technology-intensive, security requirement is high.The domestic all superstructures of LNG storage tank at present,
For stress performance, sunken tank has more advantage.Ground tank has better shock resistance and safety, is touched by aerial object
A possibility that hitting is small, and small, the features such as influence of leakage is small is influenced by wind load.
Currently, the dome installation of ground LNG storage tank generallys use after tank bottom modularization assemble by being arranged in tank
Air is injected at the construction hole of wall bottom into tank, and storage tank dome is overall increased to tank using the pressure pressure difference inside and outside tank body
Top.The shortcoming of this scheme is: (1) air inlet being arranged on concrete tank skin needs to carry out pouring envelope behind liter top
It is stifled, destroy the integrality of structure；(2) air inlet can not be set on tank skin by full underground LNG storage tank；(3) dome when rising top
Edge contacted with tank skin generate frictional force, the frictional force of all directions be it is non-uniform, this will lead to dome and deflects, tilts,
Even it can also happen that the accidents such as topple under extreme case.
Utility model content
The purpose of the utility model is to provide a kind of full underground LNG storage tanks that ejection device is risen equipped with top air inlet, this is practical
The setting of Novel storage tank can either avoid that air inlet is arranged in tank skin bottom, it is ensured that the integrality of the tank skin structure of storage tank；Simultaneously
Pulley block balance guiding device can avoid dome run-off the straight and rotation during entire jacking, it is ensured that dome is along retaining rail
Mark is steadily promoted.
Full underground LNG storage tank provided by the utility model, including LNG storage tank ontology；
The dome center of the LNG storage tank ontology is equipped with an air inlet；
Several leading blocks are equipped with around the air inlet on the dome；
Steel cable is supported by each leading block, one end of the wirerope is solid across the air inlet
Due on the cushion cap of the LNG storage tank ontology, the other end connects hoist engine by being set to the fairlead at the dome edge,
It is external that the hoist engine is fixed on the LNG storage tank sheet.
In the full underground LNG storage tank, the quantity of the leading block can be 16~48, according to specific needs (such as vault
The size on top) it determines, multiple leading blocks form leading block group.
In the full underground LNG storage tank, the fairlead is connected by buckle lifting lug, and the lifting lug is fixed on the vault
On top；The effect fixation of the fairlead simultaneously guides the wirerope.
In the full underground LNG storage tank, T shape bracket is equipped at the top of the tank skin of the LNG storage tank ontology, the wirerope is rich
It crosses the T shape bracket and connects the hoist engine, the hoist engine adjusts the dome posture for wirerope described in folding and unfolding.
In the full underground LNG storage tank, tensiometer is equipped on the wirerope at the nearly hoist engine, for measuring every
The tension of the wirerope.
In the full underground LNG storage tank, each wirerope is supported by least two directive wheel；The directive wheel
On the dome.
In the full underground LNG storage tank, the wirerope is fixed on the cushion cap by base fixture, the bottom
The fixed device in portion is welded on the built-in fitting being arranged on the cushion cap.
Pass through sheet iron in the full underground LNG storage tank, between the dome and the tank skin of the LNG storage tank ontology, prevent
Fiery cloth, adhesive tape or press strip are sealed.
The leading block, the directive wheel, the fairlead and hoist engine form pulley block balance guiding device, lead to
The air inlet of dome center setting is crossed during confined space injection air is jacked dome using pressure difference into tank,
The tensiometer and hoist engine being arranged by pulley block balance guiding device end, can adjust dome posture in real time, prevent dome from sending out
Raw inclination, rotation, so that it is guaranteed that dome can steadily be promoted along desired trajectory.With the prior art the difference is that being this reality
Air inlet is set to dome top center with novel, overcoming sunken tank can not be in the problem of tank skin bottom opening.
The utility model solves full underground LNG storage tank and can not conventionally upper tank jack in tank skin bottom opening air inlet
Problem, the dome integral installation for full underground LNG storage tank provides a kind of solution of safe and feasible；Dome structure is whole
It installs and can avoid high altitude bulk lifting operation bring construction risk；Cancel bottom air inlet, it is ensured that concrete tank wall construction
Integrality；Entire lifting operation process can balance traction device real-time monitoring by pulley block balance guiding device, top, adjust
The posture of whole dome frame, it is ensured that entire to jack the accurate, steady of process.
