Description
Technical field
The present invention is applied to low-temperature storage tank production field, and in particular to a kind of fitting of inside and outside double shell of horizontal low temperature storage tank
Method.
Background technique
The low-temperature storage tank of storage and conveying liquified natural gas LNG are binocular structure, and inner cylinder is stainless steel, outer wall packet
Heat-insulating material is covered, outer barrel is low-carbon alloy steel.Into inside outer barrel, intermediate course vacuumizes the inner cylinder fitting coated,
To guarantee to be insulated between inside and outside cylinder.
Applicant has applied for multinomial patent in terms of interior outer barrel fitting, and publication number has: CN207065071U,
The advantages of CN107649848A, CN107477353B, CN207065071U, these patents is to improve production efficiency, is suitable for
Batch production is used for connecting flange the disadvantage is that needing to weld stiffening plate in the both ends or one end of inner cylinder.Inner cylinder stainless steel
Hot-working easily causes tissue change, influences its performance, so reducing the weldering on stainless steel inner cylinder to the greatest extent for single-piece production
Connect workload.
Summary of the invention
Technical problem solved by the present invention is providing a kind of Simple sleeved method, special tooling fitting is not used, is avoided
It is welded on inner cylinder.
The technical scheme adopted by the invention is that: fitting method is the following steps are included: 1) outer barrel lies in a horizontal plane in support roller
On frame, inner cylinder is sling by I level of wirerope with First overhead traveling crane, the outer barrel import is sent into one end of inner cylinder,
It is placed on the trolley I of outer barrel import；2) the inner cylinder other end is sling by wirerope II with second overhead traveling crane, unclamps steel wire
Rope I liberates First overhead traveling crane；3) it pulls trolley or pushes inner cylinder, while second overhead traveling crane is mobile to the direction of fitting, fitting
Inner cylinder is into outer barrel；4) when II close neighbour's outer barrel import of wirerope, wirerope II is moved up, is put into trolley II from import,
Wirerope II is moved down, inner cylinder is placed on trolley II, inner cylinder is supported by trolley I and trolley II at this time；5) continue in fitting
The position that cylinder is positioned to needs, fixed trolley I or trolley II, prevent inner cylinder mobile；6) from the mounting hole of outer barrel lower part
In fill in insulating support, jack is installed on insulating support axis direction；7) jack is operated, inner cylinder is lifted, takes out two
Platform trolley；8) insulating support will be filled in remaining mounting hole, adjust whole insulating supports position according to design requirement, welding is solid
It is fixed.
The beneficial effects of the present invention are: this double shell fitting method does not use special tooling, prevent to apply on inner cylinder
Weldering, ensure that the antiseptic property of inner cylinder stainless steel.
Detailed description of the invention
Fig. 1 is that fitting starts schematic diagram；
Fig. 2 is that fitting terminates schematic diagram；
Fig. 3 is Fig. 2 schematic cross-section；
Wherein: 1- outer barrel, 2- inner cylinder, 3- wirerope I, 4- wirerope II, 5- trolley I, 6-- trolley II, 7- insulating support.
Specific embodiment
Natural gas LNG horizontal low temperature storage tank is the binocular structure of inside and outside cylinder suit, and inner cylinder is supported by insulating support,
Three are no less than on each circumference, general stablize using four insulating supports supports inner cylinder.The outer cylinder body circular seam of low-temperature storage tank
Using automatic welding two-sided welding, after inner cylinder completes, it is inserted in outer barrel.
Attached drawing 1 is that fitting starts schematic diagram, and outer barrel 1 is placed on roller frame, passes through wirerope I 3 with First overhead traveling crane
Level slings inner cylinder 2, and one end of inner cylinder 2 is sent into inside outer barrel 1, is placed on the trolley I 5 of 1 import of outer barrel, small
The supporting surface shape of vehicle is matched arc-shaped with 2 outer surface of inner cylinder, as shown in Fig. 3.Pass through steel wire with second overhead traveling crane
It restricts II 4 other ends for slinging inner cylinder 2, unclamps wirerope I 3, liberate First overhead traveling crane.It pulls trolley I 5 or pushes inner cylinder 2,
Second overhead traveling crane is mobile to the direction of fitting simultaneously, realizes that inner cylinder 2 enters fitting in outer barrel 1.When wirerope II 4 will paste
When adjacent 1 import of outer barrel, second overhead traveling crane moves up wirerope II 4, increases inner cylinder 2 at a distance from lower edge in outer barrel 1, is put into
Then trolley II 6 slowly moves down wirerope II 4, the end of inner cylinder 2 is placed on trolley II 6, inner cylinder 2 is by trolley I at this time
5 and trolley II 6 support.Continue the position that fitting inner cylinder 2 is positioned to needs, fixed trolley I 5 or trolley II 6, prevents inner cylinder
2 is mobile, and fitting is completed.As shown in Fig. 2.
Insulating support 7 is filled in from 7 mounting hole of insulating support of 1 lower part of outer barrel, as shown in Fig. 3, in insulating support 7
Jack is installed on axis direction.Operate jack so that insulating support 7 is moved to design position, at this point, two trolleies with it is interior
Cylinder 2 separates, and takes out two trolleies.The insulating support 7 of other positions is filled in mounting hole, checks whether position meets and wants
It asks.After all 7 positions of insulating support have adjusted, it is welded and fixed.
This double shell fitting method does not use special tooling, has used the necessary roller frame of workshop and overhead traveling crane, and
The tools such as jack have prevented the welding on inner cylinder although fitting efficiency is lower, ensure that the anti-corrosion of inner cylinder stainless steel
Performance.
