Ship docking block transverse and longitudinal stay wire positioning arrangement method

Abstract

The invention discloses a ship docking block transverse and longitudinal stay wire positioning arrangement method which comprises the following steps of determining a docking block position of a shipin a dock according to the length of the ship, drawing a transverse positioning datum line and a longitudinal positioning datum line on the dock bottom surface, determining the positions of all the keel piers on the transverse positioning datum line, and placing the keel piers, drawing a positioning grid group for determining the placing positions of a plurality of side piers on the dock bottom surface, and placing the side piers, after pier arrangement is completed, conducting automatic sampling inspection, and enabling the ship owner to report the placing quality of the docking blocks. According to the method, the transverse positioning lines and the longitudinal positioning lines of the side piers are pulled and transferred, so that the left-right alternate confirmation of the positioning grid group from the stern to the bow of the ship and the confirmation of the right-angle marks of the positioning points of the side piers in the positioning grid group are realized, and the searching time of the positions of the side piers is greatly saved; and meanwhile, the docking blocks can be synchronously placed in the positioning grid groups with the drawn right-angle marks, so that theplacing time of the side blocks is saved.

Description

technical field [0001] The invention belongs to the technical field of ship repair, and in particular relates to a method for positioning and arranging horizontal and vertical stay wires of ship docks. Background technique [0002] After a certain period of navigation or operation of the ship, local rust spots or flaky rust surfaces will gradually form on the outer surface of the hull plate, and sometimes even a large area of ​​severe corrosion layer will appear. At the same time, with the accumulation of shipping time, a large area of ​​thick layer of attached marine organisms will be formed on the entire underwater surface of the hull plate. In addition, some exposed parts or devices of the ship, such as: propeller, tail shaft sealing device, rudder device, diversion device, anti-rolling fin and bow and stern thrust device, etc., will also be damaged, damaged, rusted, attached to marine organisms or function Failure etc. Therefore, the ship should go to the ship repair y...

Problems solved by technology

[0005] Therefore, it takes a long time to adjust the docking pier and place the docking pier in the existing longitudinal stay wire positioning method, and it is not suitable for placing the pier of an ultra-large container ship with a huge number of piers; In the middle, despite the command of the line-drawer, there is also a phenomenon that the center point of the bottom of the dock and the intersection of the drawn cross positioning line cannot be aligned when the pier is dropped, that is, the position accuracy of the pier is unstable, and there is a large error. When the docking pier is placed with a large error, it is easy to cause damage to the hull plate and some protruding parts when the ship sits on the pier
