Description

Ship component scribing ruler and scribing method thereof Technical Field The invention belongs to the technical field of ship construction, and particularly relates to a ship component scribing ruler and a scribing method of the ship component scribing ruler. Background The ship structure is also called a hull structure. Refers to a general term for a hull structure composed of a plate material, a skeleton, and the like. Mainly comprises a ship bottom structure, a side structure, a deck structure, a bulkhead structure, a head-tail structure, a superstructure and the like. The structures of ships for different applications are also different. The ship structure should have enough strength, rigidity, stability and reliability under the action of external force, so that the general ship skeleton structure form is divided into three types of transverse skeleton type, longitudinal skeleton type and mixed skeleton type according to the main scale of the ship and the ship function. The transverse skeleton is a ship skeleton with dense transverse skeleton material, thin longitudinal skeleton material and high transverse strength. And the longitudinal skeleton is opposite to the transverse skeleton, so that the longitudinal skeleton has dense longitudinal skeleton material, thin transverse skeleton material and high longitudinal strength, and is generally suitable for large oil tankers and ore tankers. The hybrid skeleton is a hull skeleton form combining a transverse skeleton and a longitudinal skeleton, namely, a part adopts the transverse skeleton (such as a side structure) and a part adopts the longitudinal skeleton (such as a bottom and a deck structure). The form is beneficial to the total longitudinal strength of the ship body, and meanwhile, the structural members of the ship are reasonably arranged, so that the ship is generally used for large and medium-sized oil ships and cargo ships. The inner and outer shells, the inner bottom and the outer bottom and the deck adopt a longitudinal skeleton type liquid cargo ship or bulk cargo ship, and connecting members (section bars or flat steel, and crescent elbow plates with enlarged ends are arranged between the inner bottom longitudinal skeleton and the inner and outer shell longitudinal skeleton according to the standard requirements) are arranged between the inner bottom longitudinal skeleton and the outer bottom longitudinal skeleton so as to improve the fatigue strength, so that the local strength of the double-layer bottom rib plates or the side transverse diaphragm plates is improved. The modern shipbuilding industry uniformly adopts the deep fusion concept of shell, outfitting, coating and design, production and management, and shipbuilding production design is a design which is based on construction standpoint, takes high quality, high efficiency and short period into consideration, and ensures safe solving of how shipbuilding and reasonable organization of shipbuilding production. The method is characterized in that on the premise of general construction guidelines of ships, detailed design is taken as a basis, and construction areas and units are drawn according to specific conditions of shipyard construction and process stages. Work charts accounting for various process specifications, instructions and various management data, and design processes providing production information files. At present, besides some inland ship manufacturing enterprises, production designs adapting to different depths of respective shipyards are generally carried out, obvious effects are achieved, and the production designs become important means for improving shipbuilding efficiency and promoting shipbuilding progress of China. In the case of the hull industry itself, the main hull is also divided into three main stages, namely segmentation, total segmentation and berth loading. The sectioning is further composed of the procedures of blanking and processing parts, small assembly, medium assembly, large assembly (sectioning) and the like. In the small assembling picture, a longitudinal skeleton is adopted for a double-layer bottom structure, a member (a crescent elbow plate or a rib plate) for connecting an inner bottom longitudinal bone and an outer bottom longitudinal bone on a transverse rib plate is required to be welded in a small assembling stage, the rib plate small assembling picture is required to be marked with positioning data of the member (the crescent elbow plate or the rib plate), the member for connecting the inner bottom longitudinal bone and the outer bottom longitudinal bone is inclined due to arc or folding angle of the inner bottom plate and difference of transverse arrangement position and longitudinal arrangement direction of the inner bottom longitudinal bone, the end part of the member is positioned in a virtual point area of a through hole of the inner bottom longitudinal bone and the outer bottom longitudinal bone on the rib plate, so that th
