Method for measuring liquefied gas carrier C-shaped liquid tank laminated wood line

Abstract

The invention provides a method for measuring a liquefied gas carrier C-shaped liquid tank laminated wood line. The method comprises the following steps that S1, making measurement preparation; S2, determining a coordinate system and a coordinate origin of a total station; S4, collecting coordinate data of a plurality of points on the fixed end laminated wood and the movable end laminated wood byusing the total station; S5, adjusting the precision of the coordinate data according to the actual state of the C-shaped liquid tank, and exporting the coordinate data into an Excel format; S6, arranging the coordinate data of each point on the fixed-end laminated wood and the movable-end laminated wood from a three-dimensional coordinate format to a two-dimensional coordinate format; and S7, connecting the points in the two-dimensional coordinate format by utilizing drawing software, and respectively obtaining the line types of the fixed end laminated wood and the movable end laminated wood.The method has the beneficial effects that the three-dimensional coordinate data acquisition of the C-type liquid tank lamination wood line type is successfully realized, various restrictive influences caused by the field environment in the traditional measurement method are avoided, and the precision of the C-type liquid tank lamination wood line type data is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for measuring the laminated wood line shape of a C-type liquid tank of a liquefied gas ship. Background technique [0002] C-type liquid tank is the most common cargo containment system in liquefied gas carriers. Its specific structure shows two cylindrical liquid tank structures arranged side by side and fixed together. During the construction of a liquefied gas ship, the control of the matching degree of the laminated wooden line pattern on the C-type liquid tank and the hull saddle is one of the core constructions of this type of ship. One of its biggest construction difficulties is: to ensure that the C-type The liquid tank can be hoisted onto the ship smoothly. The line shape of the hull saddle needs to be matched with the actual line shape of the laminated wood on the C-type liquid tank. However, since the C-type liquid tank is built separately from the hull, ...

Problems solved by technology

[0008] It can be seen from the above steps that the existing measurement methods are cumbersome and time-consuming; they are easily affected by weather and the environment and cause measurement interruption; during the measurement process, the collected data is prone to cumulative deviations, and the accuracy of the data is easily affected; The front and rear laminated wood lines of the tank body are measured separately, and the positional relationship between the front and rear laminated wood cannot be reflected
