Abstract

The invention discloses a method for calibrating a ship's deck coordinate system with a laser marking instrument, which is characterized in that the steps of the method are as follows: 1) the ship must be in the manufacturing process of the berth, dock and wharf; 2) it must be in the ship cabin Weapon bases with horizontal accuracy requirements or multiple separate bases with the same plane requirements; 3) The hull must have correct bow and stern lines; 4) Place the laser marking instrument on the ship deck coordinate system; 5) Adjust The foot of the laser marking line, the laser line is the reference line consistent with the slope of the berth. Because the present invention adopts the existing laser marking instrument to calibrate the coordinate system of the deck of the ship, the equipment investment cost is saved and the cost is reduced. The accuracy of installing the weapon base is improved, the operation is simple and convenient, and the work efficiency and economic benefits are improved.

Description

Method for calibrating ship deck coordinate system with laser marking instrument Technical field The present invention relates to the method for installing weapon pedestal on ship, be particularly used in inclined ship platform construction and wharf mooring state, Multiple irregularly positioned split bases on the same plane (including bulkheads) are installed. Background technique Existing warship installs a plurality of same in the berth (comprising horizontal berth, inclined berth and dock) and mooring state cabin The weapon base on a plane generally adopts the following three methods: The one, conventional method: install with spirit level (inclining berth adds the block that is consistent with the slope of berth) or spirit level Weapon pedestals, this method of installing a single weapon pedestal, the accuracy of which can meet the technical requirements, such as the installation of multiple weapon pedestals, and It is difficult to meet the accuracy requirement...
