Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and more specifically, relates to a ship component marking ruler. The invention also relates to a marking method of the ship component marking ruler. Background Art

[0002] Ship structure is also called hull structure. It refers to the 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 skeletons in the inner and outer shells, inner and outer bottoms and decks, according to the requirements of the specifications, connecting members (profiles or flat steel, and the ends are also enlarged into crescent brackets to improve fatigue strength) are set between the inner and outer bottom longitudinals and the inner and outer shell longitudinals to improve the local strength of the double bottom ribs or side transverse diaphragms. The modern shipbuilding industry uniformly adopts the two integrated deep integration concepts 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 reasonably organize shipbuilding production. 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, block, and slipway loading. The block is further composed of processes such as parts cutting and processing, small group erection, medium assembly, and large assembly (block). In the small group erection, for the double-layer bottom structure adopts a longitudinal frame type, the components (crescent brackets or ribs) connecting the inner and outer bottom longitudinals on the transverse ribs need to be welded in the small group erection stage. The rib group erection should mark the positioning data of such components (crescent brackets or ribs). 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 area of ​​the inner and outer bottom longitudinal through holes on the ribs. Therefore, it is very inconvenient to mark the positioning data of the welding position lines of such components in the rib group erection. Due to the different understandings of each engineering designer, the auxiliary line settings are also different, which is easy to cause large deviations in component positioning due to measurement and marking errors. At present, the marking methods for the positioning dimensions of this type of components are divided into the following categories: 3.1. The positioning dimensions of the component are obtained by extending other intersecting structural lines or adding auxiliary line data for conversion. This type of positioning data marking and on-site reproduction is cumbersome and has the lowest work efficiency; 3.2. The vertical distance between the intersection of the component position line and the edge of the corresponding longitudinal bone through-hole and the edge of the straight line of the through-hole is used. When reproducing this vertical distance on-site, it is necessary to extend the straight edge of the through-hole into the component for a section, and then draw a parallel line with a distance of the marked dimension toward one side of the component line. The intersection of this parallel line and the edge of the through-hole is the positioning point of the component line. The same method is used to obtain another intersection at the other end of the component. The straight line connecting the two intersections is the positioning line of this type of component.It is troublesome to reproduce this type of positioning data on site, and the work efficiency is the same as Article 3.1; 3.3. Directly mark the positioning dimensions of the ends of the components (the side segment connection components are in an oblique or horizontal position). Because the ends of the components are in the longitudinal bone through-holes (usually called virtual positions), it is impossible to accurately reproduce the positioning lines of the components on site. When this type of positioning data is reproduced on site, because the actual points cannot be marked, it is often judged visually, and the deviation is large; 3.4. When the ends of the component positioning lines are extended outward and there is an identifiable and obvious intersection with the edge of the rib plate, directly mark the arc length or distance between the intersection and the identifiable characteristic point on the edge of the rib plate. This dimension is more accurate, but it is not applicable to the case of no intersection and can only be partially applicable.

[0004] Although the above four methods of marking the positioning dimensions of the positioning lines of the rib plate (or diaphragm) group erection components are different, the positioning dimensions must be marked in the group erection drawing. Before the on-site production of the group erection, 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 assembly and welding of sections. Some shipyards may leave 100mm slow welding at each end when welding such components. When the group erection is hoisted for segmental assembly, the components are bent and aligned on site according to the deviation between the components and the inner and outer bottom longitudinals, which increases the assembly and welding workload of the segmented production. According to the on-site investigation, it is generally reflected that the time to reproduce the component lines on the rib plates and diaphragms is longer than the component assembly time. Therefore, it is necessary to provide a simple and unified positioning standard to improve the positioning accuracy and work efficiency of such components. Summary of the invention

The above structure proposes an improved technical solution for the deficiencies in the prior art. When the structure is set up, there are a first substrate assembly A and a second substrate assembly B respectively. The upper part of the first substrate assembly A is a marked reference edge C, and the upper part of the second substrate assembly B is a marked reference edge C. The marked reference edge C is a straight line structure. A first positioning hole A1 and a first limiting hole A2 are arranged near the outer end of the upper part of the first substrate assembly A. A first fixed plate positioning hole A4 and a first positioning plate limiting hole A5 are arranged on the first positioning plate A3. The first fixed plate positioning hole A4 and the first positioning hole A1 are movably connected by a first rotating shaft to achieve reliable connection while ensuring that the first positioning plate A3 can be flexibly rotated relative to the first substrate assembly A. A first convex arc-shaped positioning structure A16 is arranged on the first positioning plate A3. The first arc-shaped positioning structure A16 is used to be embedded and matched with the first through groove of the ship component E to achieve the positioning of the two. A second positioning hole B1 and a second limiting hole B2 are provided near the outer end of the upper part of the second substrate assembly B, a second fixed plate positioning hole B4 and a second positioning plate limiting hole B5 are provided on the second positioning plate B3, and the second fixed plate positioning hole B4 and the second positioning hole B1 are movably connected through a second rotating shaft to achieve reliable connection while ensuring that the second positioning plate B3 can be flexibly rotated relative to the second substrate assembly B, and a convex second arc-shaped positioning structure B16 is provided on the second positioning plate B3, and the second arc-shaped positioning structure B16 is used to be embedded and matched with the second through groove of the ship component E to achieve the positioning of the two.

[0042] The connection structure D includes a first connection structure and a second connection structure. The first connection structure is: a first upper protrusion A6 and a first lower protrusion A7 are arranged near the inner end of the upper part of the first substrate assembly A, the first upper protrusion A6 and the first lower protrusion A7 are connected to the first clamping plate A8, a first connection channel is arranged between the first substrate assembly A and the first clamping plate A8, and the second substrate assembly B moves through the first connection channel; the second connection structure is: a second upper protrusion B6 and a second lower protrusion B7 are arranged near the inner end of the upper part of the second substrate assembly B, the second upper protrusion B6 and the second lower protrusion B7 are connected to the second clamping plate B8, a second connection channel is arranged between the second substrate assembly B and the second clamping plate B8, and the first substrate assembly A moves through the first connection channel.

In this way, when the outer end of the first substrate assembly A and the outer end of the second substrate assembly B are pulled outward, the relative position of the first substrate assembly A and the second substrate assembly B changes, so that the overall length of the marking ruler becomes longer. When the outer end of the first substrate assembly A and the outer end of the second substrate assembly B are pushed inward, the relative positions of the first substrate assembly A and the second substrate assembly B change, thereby shortening the overall length of the marking ruler and improving the scope of application.

[0043] A first limiting convex portion A9 is provided near the inner end of the lower portion of the first substrate assembly A, and a second limiting convex portion B9 is provided near the inner end of the lower portion of the second substrate assembly B. The above structure, the first limiting convex portion A9 and the second limiting convex portion B9 are provided to limit the ends, so as to avoid the datum edge of the marking forming an angle when the distance between the outer end of the first substrate assembly A and the outer end of the second substrate assembly B is less than about 100mm when the distance between the two ends is less than about 100mm, and the theoretical position of the component line is slightly offset due to the gap between the substrate and the bolt group. .

[0044] The first upper protrusion A6 and the first lower protrusion A7 are connected to the first clamping plate A8 through the first bolt and nut assembly A10 respectively; the second upper protrusion B6 and the second lower protrusion B7 are connected to the second clamping plate B8 through the second bolt and nut assembly B10 respectively. In the above structure, the first bolt and nut assembly A10 can reliably connect the first substrate assembly A and the first clamping plate A8, and the second bolt and nut assembly B10 can reliably connect the second substrate assembly B and the second clamping plate B8, ensuring that the two are reliably connected.

[0045] A first through groove E1 is provided on one side of the ship component E, and the first through groove E1 includes a groove portion E2, a through hole portion E3, a side portion E4 and a straight edge portion E6. A second through groove E5 is provided on the other side of the ship component E, and the second through groove E5 includes a groove portion E2, a through hole portion E3, a side portion E4 and a straight edge portion E6. The above structure is the setting of the structure of the ship component. In order to achieve marking, a marking ruler is provided to be suitable for the structure of the ship component, and the marking operation is completed conveniently, quickly, simply and accurately.

[0046] The first fixed plate positioning hole A4 on the first positioning plate A3 includes an upper first fixed plate positioning hole A11 (a concentric hole) and a lower first fixed plate positioning hole A12 (an eccentric hole), and the first positioning plate limiting hole A5 includes an upper first positioning plate limiting hole A13 (corresponding to the concentric hole) and a lower first positioning plate limiting hole A14 (corresponding to the eccentric hole). A raised shoulder A17 is also provided on the outer side of the first positioning plate A3. In the above structure, the upper first fixed plate positioning hole A11 and the upper first positioning plate limiting hole A13 are the first fixed plate positioning holes and the first positioning plate limiting holes in the positive position, and the lower first fixed plate positioning hole A12 and the lower first positioning plate limiting hole A14 are the first fixed plate positioning holes and the first positioning plate limiting holes that deviate by a certain distance. In this way, the connection and limiting of different positions of the first positioning plate are realized. The second fixed plate positioning hole B4 on the second positioning plate B3 includes an upper second fixed plate positioning hole B11 (a concentric hole) and a lower second fixed plate positioning hole B12 (an eccentric hole), and the second positioning plate limiting hole B5 includes an upper second positioning plate limiting hole B13 (corresponding to the concentric hole) and a lower second positioning plate limiting hole B14 (corresponding to the eccentric hole). A raised shoulder is also provided on the outer side of the second positioning plate B3. In the above structure, the upper second fixed plate positioning hole B11 and the upper second positioning plate limiting hole B13 are the second fixed plate positioning holes and the second positioning plate limiting holes in the positive position, and the lower second fixed plate positioning hole B12 and the lower second positioning plate limiting hole B14 are the second fixed plate positioning holes and the second positioning plate limiting holes that deviate by a certain distance. In this way, the connection and limiting of different positions of the second positioning plate are realized. The marking ruler of the present invention is designed according to the reverse positioning method of the component positioning line. The rotation axis of the positioning hole can pass through the concentric hole or the eccentric hole (the concentric hole and the eccentric hole are eccentric by a certain distance, such as 6mm, etc.). The positioning concentric hole and the positioning eccentric hole and the limiting concentric hole and the limiting eccentric hole respectively correspond to the non-biased and biased installation or two node forms of the longitudinal bone connecting component of the component. For the non-biased installation, the rotation axis passes through the concentric hole, and for the biased installation, the rotation axis passes through the eccentric hole. The limiting hole also corresponds to the insertion of the limiting pin. The concentric hole of the positioning plate is used as the hole through which the rotation axis passes, which corresponds to the situation that there is no deviation value for the longitudinal bone corner point of the ship component, that is, the rotation axis passes through the concentric hole, and the limiting pin passes through the corresponding concentric limiting hole. When the eccentric hole of the positioning plate is used as the rotation axis, that is, when there is a deviation value between the connecting component and the corner point of the longitudinal bone, the rotation axis passes through the eccentric hole, and the limit pin passes through the corresponding eccentric limit hole, the rotation angle of the positioning plate on both sides of the rotation axis effectively meets the deflection angle of the component connecting the inner and outer bottom (shell) longitudinal bones in the ship design.

[0047] The first positioning hole A1 of the first substrate assembly A and the first fixed plate positioning hole A4 of the first positioning plate A3 are connected by a first rotating shaft; the second positioning hole B1 of the second substrate assembly B and the second fixed plate positioning hole B4 of the second positioning plate B3 are connected by a second rotating shaft. In the above structure, the rotating shaft can reliably realize the flexible connection between the positioning plate and the substrate assembly.

[0048] The first positioning plate A3 is provided with a first adjustment handle A15 near the outer end, and the second positioning plate B3 is provided with a second adjustment handle B15 near the outer end. In the above structure, the adjustment handle is convenient for operators to use when adjusting the position of the positioning plate relative to the base plate assembly.

The steps are simple, can save a lot of working time, and reduce the intensity of marking operation. The marking steps of the ship component marking ruler marking method are:

Positioning on the ship component E; the operator rotates the second positioning plate B3, and adjusts the direction of the second positioning plate B3 relative to the second substrate assembly B, so that the second arc-shaped positioning structure B16 of the second positioning plate B3 is embedded in the groove portion E2 of the second through-groove E5, so as to realize the positioning of the second positioning plate B3 on the ship component E; S3: the operator presses the ship component marking ruler with his left hand to fit the ship component, and holds the marking pen with his right hand, and marks the marking reference edge C on the upper part of the first substrate assembly A and the marking reference edge C on the upper part of the second substrate assembly B, and the marking extends from the position of the ship component E close to the first through-groove E1 to the position close to the second through-groove E5. S4: Repeat the above steps to complete the marking operation of the remaining ship components E.
