Abstract

The invention discloses a lineation method utilizing a portal lineation device. The lineation method utilizing the portal lineation device specifically includes the following steps that a to-be-lineated position is found out on a main board; the portal lineation device is fixed to the to-be-lineated position; left and right two lineation pens are adjusted to proper positions, and then a two-way telescopic connection plate is rotated in the circumferential direction to draw a boundary line for hole opening; and the positions of the lineation pens are kept unchanged, the two-way telescopic connection plate is adjusted to a set orientation, then the two lineation pens are moved in the direction of the center of the two-way telescopic connection plate, and a component installing line is drawnwithin the boundary line for hole opening. The lineation method utilizing the portal lineation device is easy to use, convenient to operate and capable of effectively lowering the measuring operationcost, improves the lineation efficiency and the lineation precision to a very large extent, lowers the labor force consumption of lineation operation, and shortens the construction period.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a marking method using a portable marking device. Background technique [0002] At present, in the process of hull production, circular openings on the main deck often occur, and when the center of the circle is used as the center and rotated at a fixed angle to draw the component installation line, there is no relevant tooling available on site for the operation, and we can only rely on The technical department uses AUTOCAD software to make angle templates, and then sticks the angle templates on the steel plate for marking. Low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to design a scribing method using a portable scribing device, which solves the problems of cumbersome scribing methods, low scribing accuracy and low efficiency of the traditional scribing method. [0004] In order...
