Description
Technical field
The present invention relates to shipbuildings, are related specifically to a kind of installation for super-container vessel crack arrest steel hatch coaming
Method.
Background technology
Nowadays, Container shipping ship hatch coaming more and more uses high intensity crack arrest steel with main deck region, to reduce clean ship
The use of weight, crack arrest steel brings great challenge to the installation in advance of hatch coaming.Currently, the crack arrest of super-container vessel
The main profit of steel hatch coaming installation carries out with the following method：Crack arrest steel hatch coaming is subjected to sleeping state installation in the segmentation stage, or will
Crack arrest steel hatch coaming carries out normal state installation in the dock stage.Above two installation method has following deficiency：
If the first, by crack arrest steel hatch coaming in the sleeping state installation of segmentation stage, due to crack arrest steel hatch coaming longitudinal wall plate and master
It is K-type groove between deck, when single-sided welding will bring the installation accuracy of hatch coaming great influence, if passing through a large amount of work
Skill is reinforced, then is easy the risk that there is damage crack arrest steel during freezing and removing process conditions.
If second, by crack arrest steel hatch coaming dock stage normal state install, due to crack arrest steel hatch coaming longitudinal wall plate with
Fillet welding gap between main deck be 0 ~ 3mm, torsion box and hatch closed structure by shelving, transporting for a long time, handling, weldering
It the processes such as connects, has accumulated which that bigger trueness error, such case lead to crack arrest steel hatch coaming longitudinal wall plate and torsion box master
Fillet welding gap between deck is easy to overproof, and hatch coaming is installed in the dock stage, also by strong influence dock week
Phase.
Invention content
For problems of the prior art, the present invention provides a kind of for super-container vessel crack arrest steel hatch coaming
Installation method, overcome in the prior art that crack arrest steel hatch coaming installation risk is big, installation accuracy is low, the set-up time is long, shadow
The problem of ringing ship building period.
To achieve the above object, the present invention uses following technical scheme：
A method of it being used for the installation of super-container vessel crack arrest steel hatch coaming, which to include following step
Suddenly：
The vertical manufacture of the affiliated group of S1, torsion box carries out jigsaw to mainboard, after jigsaw size qualification, then welding equipment main deck
Group, longitudinal wall group and outside floor；
S2 is arranged in main deck to organize and founds jig frame special, and the moulding bed of group moulding bed is made of angle steel in main deck, on moulding bed
Horizontal line is set, to ensure be bonded rate of the main deck group with moulding bed, moulding bed is organized in the main deck group and main deck
Between be mechanically fixed by assembling horse, after crack arrest steel hatch coaming precision qualification, crack arrest steel hatch coaming is lifted into upper main deck group
It is installed, the longitudinal wall plate of the main deck group is close to diagonal brace, is welded, will be led between group moulding bed in diagonal brace and main deck
Deck group, crack arrest steel hatch coaming are mechanically fixed with group moulding bed in main deck respectively, to realize the positioning of component；
S3, crack arrest steel hatch coaming organizes vertical stage welding equipment in main deck, between crack arrest steel hatch coaming and main deck group
After assembly, start to weld, the angle between the transverse bracket end and the deck structure of main deck group of crack arrest steel hatch coaming
Weld seam first welds a part, the flat fillet weld between the longitudinal wall plate and deck structure of crack arrest steel hatch coaming using double-sided symmetrical, point in
Backstep welding continues to complete the welding of fillet weld between transverse bracket and deck structure after longitudinal wall plate welds, when welding
The precision of crack arrest steel hatch coaming should be monitored in real time, if precision is overproof, welding method is adjusted in time, to ensure crack arrest steel hatch coaming
The precision of welding equipment is needed to be aided with firer and be corrected if precision exceeds allowable range, until precision is qualified, is eventually formed complete
Hatch coaming main deck in organize it is vertical；
S4, torsion box longitudinal wall organized in expanding it is vertical make, group in group, two deck groups, main deck in longitudinal wall plate in torsion box
It after vertical precision qualification, sets and organizes moulding bed in main deck, the ground such as contour line, waterline, rib inspection line are outputed on manufacturing field
Line builds basal plane to be organized in longitudinal wall plate in torsion box, lifts successively and organizes vertical in two deck groups, main deck, above-mentioned group vertical
Welding equipment process follows strictly assembling and welding process progress, and welding equipment process takes the mode of low current, multi-pass welding to become to reduce welding
Shape is formed in the torsion box longitudinal wall expansion of precision qualification to organize and be stood；
S5, big group of torsion box segmentation, torsion box longitudinal wall are organized in expanding in vertical and outside plate after the vertical precision qualification of group, with outside plate
Middle group is stood as installation base surface, will torsion box longitudinal wall expand in organize and found welding equipment hanging horse and after technique reinforces, turn over welding equipment in outside plate
Middle group vertical, and vertical bow stern both ends setting I-steel is organized in torsion box, respectively carries out crack arrest steel hatch coaming and main deck group
Connection, to prevent torsion box to be segmented deformation during handling is turned over, in this stage, the outfititems such as box column above main deck
It can be installed, torsion box is segmented and carries out technique correction, form torsion box segmentation.
When outside distance ＞ 1m of the floor away from component end described in step S1, false compartment work is set in main deck group
Skill part.
Weld suspender belt turning tool in one end of mainboard described in step S1.
It does not weld between diagonal brace and crack arrest steel hatch coaming, is set between the carling and main deck group of crack arrest steel hatch coaming
Set active support tube, for assisting the positioning of hatch coaming, the active support tube and main deck group and crack arrest steel hatch coaming it
Between support fix, do not weld；Horse and group moulding bed welding in main deck are assembled, since main deck group is using crack arrest
Therefore steel is assembled and is mechanically fixed between horse and main deck group, do not welded.
Compared with prior art, beneficial effects of the present invention are：1. present invention employs groups in a kind of special main deck
Vertical jig frame special, reduces the use of process conditions in crack arrest steel hatch coaming installation process, reduces the risk of crack arrest steel damage；②
The present invention in the way of point middle backstep welding, has by the way that crack arrest steel hatch coaming is organized vertical stage normal state installation in main deck
Conducive to the installation accuracy of crack arrest steel hatch is promoted, the damage risk for freezing and removing the crack arrest steel that process conditions are brought is reduced, by cabin
The erection stage that mouth encloses is shifted to an earlier date, and is created conditions for the installation in advance of other outfititems, to effectively shorten entire collection
The construction period of vanning ship；3. the present invention accelerates the installation speed of crack arrest steel hatch coaming, and pacifies for other hatch coaming outfititems
Dress creates condition in advance, and the present invention greatly shortens the construction period of ship, since crack arrest steel hatch coaming is in segmentation group
Vertical stage normal state installation, method using the present invention can also pacify the outfititems such as the box column of hatch board, supporting block box in advance
Dress, to greatly accelerate the construction speed of super-container vessel.
