Abstract
Ton bulk goods deadwood pre-installs closure workmanship, and tailing axle steel-casting, and end of freezing are installed in lifting tail fin prelocalization；Casting steel casting tail fin and tailing axle steel-casting will make together, it is ensured that its end connection consistency；The front and back position of tail fin is first determined, and is ensured using rib position mark, in advance the mark line on tail fin and tailing axle steel-casting, as long as alignment front and back position determines that the installation site of tail fin；A tail fin of position level is lifted first, and the data point of theory is measured on correspondence drawing and mark is carried out at theoretical value strong point on tail fin, and measures its numerical value using three-dimensional full battle instrument, it is ensured that be consistent with theoretical value；Installation is compared with angular templet；An other tail fin is lifted again, and the height of every meter of 45 degree of risings is calculated in theory, and every meter of place of tail fin carries out mark, and the positioning that its difference in height ensures its short transverse is measured using three-dimensional full battle instrument；Spot welding is fixed and is fixed with support, and completion is closed up in whole tail fin prepackage.
Description
Technical field
Closure workmanship is pre-installed the present invention relates to ton bulk goods deadwood, belongs to technical field of ships.
Background technology
With the development of modern science and technology, shipping industry is increasingly to high-end development, from original wooden boat to ten thousand tons
Level steel vessel development, especially ton bulk freighter, substantially increase the transportation power of ship, the technique for also improving shipbuilding,
But also very backward in terms of tail fin prepackage is closed up, the angle or position often installed are uneven, make navigation direction unstable, and
Deflecting is unstable, is a urgent problem.
The content of the invention
Closure workmanship is pre-installed it is an object of the invention to provide ton bulk goods deadwood.
The problem to be solved in the present invention is the deficiency that existing tail fin prepackage closure workmanship falls behind.
To realize the purpose of the present invention, the technical solution adopted by the present invention is：
1st, ton bulk goods deadwood prepackage closure workmanship, it is characterised in that：Comprise the following steps
A needs the good tailing axle steel-casting of location and installation, and end of freezing before lifting tail fin；
B when casting steel casting, tail fin and tailing axle steel-casting will together with make, it is ensured that the one of its end connection
Cause property；
C first determines the front and back position of tail fin, and is ensured using rib position mark, in advance in tail fin and tailing axle steel-casting subscript
Note line is carried out, as long as alignment front and back position has determined that the installation site of tail fin；
D lifts a tail fin of position level first, and the data point of theory is measured on correspondence drawing, and on tail fin
Mark is carried out at theoretical value strong point, and its numerical value is measured using three-dimensional full battle instrument, it is ensured that be consistent with theoretical value, it is ensured that coplanarity；
It is compared again with angular templet after e installations；
F lifts an other tail fin again, and the height of every meter of 45 degree of risings is calculated in theory, and is carried out at every meter of place of tail fin
Mark, and measure the positioning that its difference in height ensures its short transverse using three-dimensional full battle instrument；
G spot welding is fixed and is fixed with support, and completion is closed up in whole tail fin prepackage.
Advantages of the present invention：Technology is closed up using the tail fin prepackage of this technique, makes navigation direction stable, and assist conversion side
To steady, there should be extensive market prospects.
Brief description of the drawings
Fig. 1 is the stereogram that ton bulk goods deadwood of the present invention pre-installs closure workmanship.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is further illustrated.
By taking 38670DWT bulk goods deadwood prepackage closure workmanship as an example, comprise the following steps：
A needs the good tailing axle steel-casting of location and installation, and end of freezing before lifting tail fin；
B when casting steel casting, tail fin and tailing axle steel-casting will together with make, it is ensured that the one of its end connection
Cause property；
C first determines the front and back position of tail fin, and is ensured using rib position mark, in advance in tail fin and tailing axle steel-casting subscript
Note line is carried out, as long as alignment front and back position has determined that the installation site of tail fin；
D lifts a tail fin of position level first, and the data point of theory is measured on correspondence drawing, and on tail fin
Mark is carried out at theoretical value strong point, and its numerical value is measured using three-dimensional full battle instrument, it is ensured that be consistent with theoretical value, it is ensured that coplanarity；
It is compared again with angular templet after e installations；
F lifts an other tail fin again, and the height of every meter of 45 degree of risings is calculated in theory, and is carried out at every meter of place of tail fin
Mark, and measure the positioning that its difference in height ensures its short transverse using three-dimensional full battle instrument；
G spot welding is fixed and is fixed with support, and completion is closed up in whole tail fin prepackage.
The application method of the present invention：The ton bulk freighter that the manufacture of this technique is completed, the accurate nothing of tail fin installation site are installed
By mistake, angle adjustment was carried out during navigation by original 1 hour and becomes angle adjustment correction in 3 hours, navigation is got up safer
Reliably.
