Description

Technical Field

[0001] The present invention belongs to the technical field of shipbuilding, and more specifically, relates to a device for marking positioning lines of ship components. The present invention also relates to a method for marking positioning lines of ship components. Background Art

[0002] Ship structure, also known as hull structure, is a general term for hull structures composed of plates and frames. It mainly includes bottom structure, side structure, deck structure, bulkhead structure, bow and stern structure and superstructure. The structure of ships for different purposes is also different. The ship structure should have sufficient strength, rigidity, stability and reliability under the action of external forces. Therefore, according to the main dimensions and functions of the ship, the hull frame structure is usually divided into three types: transverse frame type, longitudinal frame type and mixed frame type. Transverse frame type: This type of hull frame has denser transverse frame materials and sparser longitudinal frame materials, and has better transverse strength. Longitudinal frame type: In contrast to the transverse frame type, the longitudinal frame type has denser longitudinal frame materials and sparser transverse frame materials, and has better longitudinal strength. It is generally suitable for large oil tankers and ore carriers. Mixed frame type: This is a hull frame type that combines the transverse frame type and the longitudinal frame type, that is, part of the transverse frame type (such as the side structure) and part of the longitudinal frame type (such as the bottom and deck structure) are adopted. This form is beneficial to the overall longitudinal strength of the hull, and at the same time makes the layout of the ship's components reasonable. It is generally adopted by large and medium-sized oil tankers and cargo ships.

[0003] For liquid cargo ships or bulk carriers with longitudinal frames in the inner and outer shells, inner and outer bottoms and decks, connecting members (profiles or flat steel, with ends enlarged into crescent brackets to improve fatigue strength) are arranged between the inner and outer bottom longitudinals and the inner and outer shell longitudinals according to the requirements of the specifications to improve the local strength of the double bottom ribs or side transverse bulkheads.

[0004] The modern shipbuilding industry uniformly adopts the concept of deep integration of "hull, outfitting, coating" and "design, production, management". Shipbuilding production design is a design that starts from the construction standpoint, considers high quality, high efficiency, short cycle and ensures safety to solve how to build ships and how to organize shipbuilding production reasonably. It is based on the overall construction policy of the ship, based on detailed design, according to the specific conditions of the shipyard construction, and drawn according to the construction area and unit of the process stage. It takes into account various process technical indicators, instructions and various management data work charts, as well as the design process of providing production information documents. At present, except for some inland ship manufacturing enterprises, production design that adapts to the different depths of their respective shipyards is generally promoted, and significant results have been achieved. Production design has become an important means to improve shipbuilding efficiency and promote the progress of my country's shipbuilding. As far as the hull profession itself is concerned, the main hull is also divided into three main stages: block, total block, and slipway loading. And the block is further composed of parts cutting, processing, small assembly, medium assembly, large assembly (block) and other processes. In the group elevation drawing, for the double-layer bottom structure adopting the longitudinal frame type, the components (crescent brackets or rib plates) connecting the inner and outer bottom longitudinals on the transverse ribs need to be welded in the group elevation stage, and the rib group elevation drawing should mark the positioning data of such components (crescent brackets or rib plates). Because the inner and outer bottom plates have arcs or angles, and the differences in the transverse arrangement positions and longitudinal arrangement directions of the inner and outer bottom longitudinals, the components connecting the inner and outer bottom longitudinals are skewed, and the ends of the components are in the virtual point areas of the through holes of the inner and outer bottom longitudinals on the ribs. Therefore, it is inconvenient to mark the positioning data of the welding position lines of such components in the rib group elevation drawing. Because each engineering designer has different understandings, the auxiliary line settings are also different, which can easily lead to large deviations in component positioning due to measurement and marking errors. At present, the marking methods for the positioning dimensions of such components are divided into the following categories: 3.1, by extending other intersecting structural lines or adding auxiliary line data for conversion, the positioning dimensions of the component are obtained. This type of positioning data marking and on-site reproduction are cumbersome and have the lowest work efficiency; 3.2, using the intersection of the component position line and the edge of the corresponding longitudinal bone through hole to mark the positioning dimensions, it is necessary to use the vertical distance between the intersection and the straight surface (18) of the longitudinal bone through hole for positioning, and the other end of the component is also obtained by the same method. Another intersection, the two intersections are connected to form a straight line, which is the positioning line of this type of component. This type of positioning data on-site reproduction requires adding an extension line of the straight surface (18) of the longitudinal bone through hole, and drawing a parallel line according to the marked distance to intersect with the edge of the longitudinal bone through hole to obtain the positioning point. The reproduction process is more troublesome, and the work efficiency is the same as Article 3.1; 3.3, directly marking the positioning dimensions of the end of the component (the side segment connection component is in an oblique or horizontal position). Because the end of the component is in the longitudinal bone through hole (usually called a virtual position), it is even more impossible to accurately reproduce the positioning line of the component on-site.When such positioning data is reproduced on site, it is often judged visually because the actual point cannot be marked, and the deviation is large; 3.4. When the end of the component positioning line is extended outward and there is an identifiable obvious intersection with the edge of the rib plate, the arc length or distance between the intersection and the identifiable characteristic point on the edge of the rib plate is directly marked. This dimension is more accurate, but it is not applicable to the case of no intersection and can only be partially applicable. The above four methods of marking the positioning dimensions of the positioning lines of the rib plate (or side) group vertical components are different, but the positioning dimensions must be marked in the group vertical drawing. Before the on-site production of the group vertical, it is necessary to reproduce one by one according to the marked dimensions in the drawing. The process operation requires several steps of conversion, and some methods provide a virtual position point that can only be judged visually. Therefore, the drawing of the component positioning line is prone to deviation, resulting in rework during the segment welding. Some shipyards use 100mm slow welding at each end when welding such components. When the group vertical is hoisted for segment assembly, the component is bent and aligned on site according to the deviation between the component and the inner and outer bottom longitudinals, which increases the assembly and welding workload of the segment production.
