Description
Technical field
The present invention relates to shipbuilding and repair field, more particularly, to a kind of secondary localization method to lie up of ship.
Background technology
In the modern times repair shipbuilding industry, ship, which needs to be drawn into dock, constructs, and mainly includes dry dock and floating dock,
This just needs to position dockage.
With scientific and technological progress, total powerstation in the application for building bateau neck domain, make the secondary localization method to lie up of ship also with
Change, substantially reduce positioning workload, and position more accurate.New method is compared with original method, and also there are following for original method
Shortcoming：
1. in order to ensure the positional accuracy of ship longitudinal direction, need to set longitudinal register point on ship plank, using sharp
Light instrument ensures laser and anchor point in same rib plane, but whether laser needs artificial observation luminous point in anchor point
On, in this process, viewing angle, distance and due to varying with each individual etc., position error is very big, often results in positioning and loses
It loses.
2. in order to ensure the correct of half width position of ship bow stern, need to set two wooden rules respectively at parallel (middle) body position,
In position fixing process, outside plate is measured to the distance of wing wall, guarantee measured distance is consistent with theoretical distance, but must in measurement process
It must ensure that wooden rule is vertical with outside plate, this is extremely difficult in practical operation, simultaneously because the molded breadth of ship does not include outer plate thickness,
And measured distance does not include outer plate thickness then, the outer plate thickness of bow stern measured zone may also be inconsistent, easy when causing to position
Ignore this point, this can all cause positioning to fail.
For these reasons, positioning failure often occurs for existing positioning process, needs to discharge water again, repositions, takes
When it is laborious, increase dock cycle and expense.

Length direction is in place；
7th, positioned at the coordinate of the total station survey third anchor point of ship stern wing wall, as the Y coordinate Y of third anchor point3Meet
During following equation, ship stern width direction is lain up at this time in place,
Y3=L-B/2-S3
Wherein, distances of the L for position baseline and ship dock position center line, molded breadths of the B for ship, S3It is outer at third anchor point
Plate thickness；
8th, positioned at the coordinate of the 4th anchor point of total station survey of ship fore body wing wall, as the Y coordinate Y of the 4th anchor point4Meet
During following equation, ship stern width direction is lain up at this time in place,
Y4=L-B/2-S4
Wherein, S4For the outer plate thickness at the 4th anchor point；
9th, as X in above-mentioned seven, eight, nine steps2、Y3、Y4Data when being satisfied by formula condition, ship's fix is completed.
In a kind of above-mentioned secondary localization method to lie up of ship of the present invention, the position of first anchor point corresponds to ship
Oceangoing ship 34# ribs position, second anchor point are located at the cabin antetheca outside plate of ship 34# ribs position.
In a kind of above-mentioned secondary localization method to lie up of ship of the present invention, the length of the position baseline is not less than
Captain.
In a kind of above-mentioned secondary localization method to lie up of ship of the present invention, the third anchor point and the 4th anchor point
It is respectively positioned on deck and the junction of outside plate.
In a kind of above-mentioned secondary localization method to lie up of ship of the present invention, the angle of inclination of the total powerstation and ship
Trim angle it is consistent.
Based on above-mentioned technical proposal, the present invention has the following advantages compared with the prior art：
1. this method can ensure accurately to arrange docking block, ship's fix is made to be arranged with docking block and ensures consistency, localization method precisely,
Simply.
2. this method passes through the first anchor point, the second anchor point, third anchor point, the 4th anchor point and position baseline
Lay, cooperation total powerstation cause ship is secondary lie up when the simpler convenience of operation, instead of a large amount of manual labor, section
Human resources are saved, so as to improve production efficiency and save production cost.
3. the accuracy of positioning can be realized by carrying out positioning using this method so that the success rate of dockage carries significantly
Height shortens the period that lies up, and then cost-effective.
