Abstract

The invention discloses a marking device for allowance lines and inspection lines in hull construction. The marking device for allowance lines and inspection lines in hull construction comprises a marking board. The surface of the marking board is provided with scale. The lower end face of the tail of the marking board is in a right-angled protrusion structure. Two parallel slides are made on the surface of the right-angled protrusion structure. The marking device is also provided with a moving target board moving along the slides. Four corners of the moving target board are provided with shaft holes, and bolt sets penetrate into the shaft holes to immobilize the moving target board on the slides. The surface of the moving target board is provided with target board scale which is level to the lower end face of the moving target board. By the use of the marking device for allowance lines and inspection lines in hull construction, the problem in marking flat straight segmented allowance lines is well solved, production speed is increased, quality of precision marking is improved, production cost is saved, and competitiveness of enterprises is increased. The marking device for allowance lines and inspection lines in hull construction is applicable to marking on the ground after assembly of flat straight segments.

Description

technical field [0001] The invention relates to a line marking device, in particular to a device used for marking the margin line and the inspection line of the straight section of the hull. Background technique [0002] In the process of hull construction, the shipyard generally uses laser theodolite, a relatively precise detection tool, to pre-trimming the sections, that is, the laser theodolite is used to draw the section allowance line after the section is manufactured, and the semi-automatic cutting torch is used to cut the section. Surplus cutting to achieve no-surplus assembly on the berth, and good results have been received. Therefore, if the subsection margin line can be quickly and accurately drawn, it can be conveniently hoisted and closed up in sections and quickly installed and positioned, which is of great significance for the shipyard to shorten the ship construction cycle and improve the competitiveness and economic benefits of the shipyard. . At present, ...
