Abstract

The invention discloses a kind of hanging method for two phase stainless steel chemical tanker transverse bulkhead medial section (hereinafter referred to as c-type compartment is segmented), construction and total group of this method for the segmentation of c-type compartment reduce lifting deformation, it is ensured that Hoisting Security.Place when due to c-type compartment sectional construction and total group is different, and lifting equipment has very big difference, and is segmented that final state is also different, this results in hanging method when c-type compartment sectional construction and total group to there is very big difference.The device parameter for the build the side that this method is segmented according to c-type compartment, sectional construction turn over the arrangement turned over using left and right;State when according to c-type compartment block assembly is always segmented into anti-state, therefore lifts by the way of turning over up and down when group.Present invention ensure that the lifting during c-type compartment sectional construction and total group needs, solve the insufficient unfavorable factor of build the side appointed condition, provides guarantee for the smooth construction and total group of c-type compartment segmentation.

Description

A kind of hanging method for two phase stainless steel chemical tanker transverse bulkhead medial section
Technical field
The invention belongs to field of shipbuilding, and in particular to one kind is among two phase stainless steel chemical tanker transverse bulkhead points The hanging method of section.
Background technique
As the chemical tanker specification that company is accepted is increasing, and the size of its transverse bulkhead segmentation
Also increasing, this just increases difficulty to the construction of transverse bulkhead segmentation.Transverse bulkhead be segmented connected double-layer bottom, mediastinum cabin, Deck panel, influence of the quality of construction precision to the precision of whole ship is very big, and due to the special material of its two phase stainless steel Matter, this requires us to carry out strict control to its building course.
Usually we design carbon steel segmentation Hoisting Program when, hanging ring is generally located in structure.Chemical tanker due to Its special material cannot directly adopt common carbon steel hanging ring.And transverse bulkhead segmental structure itself is weaker, needs to increase It is a large amount of to reinforce.Therefore, we are when designing the Hoisting Program of transverse bulkhead segmentation, it may be considered that are arranged on segmentation is reinforced and hang Point.Construction process based on existing lifting equipment parameter and segmentation, We conducted two phase stainless steel chemical tanker transverse bulkheads The hanging method of medial section is studied, to reduce the control of site workload and compartment construction precision, reach precision shipbuilding and at The purpose of this saving.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of in two phase stainless steel chemical tanker transverse bulkhead Between the hanging method that is segmented, solve the problems, such as that the existing build the side lifting equipment lifting altitude of segmentation is insufficient, built in conjunction with segmentation The characteristics of process is turned over often is made, subsection deformation and site workload are reduced.
To achieve the above object, the invention adopts the following technical scheme:
A kind of hanging method for two phase stainless steel chemical tanker transverse bulkhead medial section, method includes the following steps:
Weld seam on S1, welding c-type compartment segmentation stern end face;
Weld seam on S2, stern end face installs stern end face stiffening profile after being soldered, and installs sectional turn-over on transverse bulkhead groove profile port Hanging ring;
S3, the segmentation of c-type compartment is turned over 180 ° along Z axis for the first time, until bow end face is upward;
Then segmentation weld seam on S4, welding bow end face installs bow end face and is segmented stiffening profile;
S5, the segmentation of c-type compartment is turned over 180 ° along second of z-axis, until stern end face is upward, segmentation is turned over 180 ° for the second time and used Hanging ring it is identical as first time, on the profile that auxiliary hook when block assembly turns over should be mounted on segmentation stern end face is reinforced, in this way Carbon steel hanging ring need to be installed, and the installation that additionally profile is reinforced caused by being avoided that because of hanging ring installation;
S6, the outfititem that stern end face is installed on the stern end face, and block assembly is installed on the stiffening profile of stern end face and is turned over Body hanging ring;According to the lifting equipment in block assembly place, the main hook that always group is turned over should be mounted on segmentation center of gravity, and what is be segmented adds It is mounted in the front/rear end of segmentation by force, it is therefore desirable to link up the reinforcement of segmentation, the main hook that such block assembly turns over is just It can be mounted in reinforcement;
S7, stern end face stiffening profile and bow end face segmentation stiffening profile are connected with several transition profiles, on the transition profile The total group of installation turns over hanging ring;Main hook is a suspension centre when block assembly turns over, and when lifting can laterally generate component, it is therefore desirable to Laterally increase a reinforcement;
S8, transition profile is connected with lower mouth stiffening profile, the transverse component in the reinforcement of lower mouth can be thus offset, is kept away Exempt from lower mouth to reinforce generating transversely deforming;
S9, the segmentation of c-type compartment turn over 90 ° clockwise around y-axis and carry out total group, and according to total group of state of segmentation, segmentation is using up and down It turns over and carries out total group.
The extending direction of stern end face stiffening profile and the direction where weld seam are mutually perpendicular to;The segmentation of bow end face is reinforced The extending direction of material is mutually perpendicular to the direction where segmentation weld seam, the main deformation for controlling height of lift direction.
The sectional turn-over hanging ring, block assembly turn over hanging ring, total group turn hanging ring is carbon steel hanging ring, hanging ring and groove profile Port is attached using stainless steel plate.Meanwhile reinforcement to be installed in segmentation groove profile.
The weld seam and segmentation weld seam are all made of automatic welding, current in order to not influence automatic welding carriage, and weldering stern end face adds It is strong to need to install again after the completion of stern edge weld;The reinforcement of weldering bow end face needs to pacify again after the completion of bow edge weld Dress.
In the present invention, since fragment size is bigger, height is very high, and internal field turn place lifting equipment is height-limited, Sectional turn-over can only be turned over by the way of 180 ° using left and right.It turns over auxiliary hook and uses same group of hanging ring.
The sectional turn-over hanging ring is B-15T hanging ring, and quantity is 8, is symmetrically distributed in the two sides of stern end face.
It is A-20T hanging ring that the block assembly, which turns over hanging ring, and quantity is 2, is symmetrically distributed in the reinforced of stern end face On material.
The total group of turn hanging ring is A-30T hanging ring, and quantity is 2, and the total group of turn hanging ring is arranged in transiens The both ends of material.
Compared with prior art, the invention has the benefit that
It is turned in conceptual design in first time, by reasonable Arrangement hanging ring, makes full use of the structural strength of segmentation itself, avoid Segmentation is reinforced turning over deformation caused by can not installing because of bow end face;
Total group is turned over hanging ring to be provided entirely in reinforcement, the time of hanging ring is cut off at the scene of eliminating, and avoids the waste of hanging ring.
