Description

Technical Field

[0001] This utility model relates to devices in the field of shipbuilding and design, and in particular to a device for marking ship section allowances. Background Technology

[0002] In previous ship assembly and positioning work, according to the construction process, each independent segment's docking port had a cutting allowance. After adjusting the plate state of all segments to be assembled, the allowance cutting value was determined and the allowance was cut. The allowance cutting value was calculated based on the rib spacing at the assemblies and the lengths of the two segments to be assembled. During cutting, the allowance was removed based on the allowance line drawn on the allowance segment.

[0003] Currently, the method for drawing allowance lines is to draw lines on the segments with allowance ends based on the zero-allowance end. The clean material segment is usually the zero-allowance end after machining, so a measuring tape is often used to mark several points on the allowance segment according to the determined allowance cutting value, and a ruler is used to connect the points to form the allowance line.

[0004] In actual construction operations, deviations are prone to occur when connecting the allowance lines. This often results in over-cutting or under-cutting at certain points during the joining and closure stage after the allowance cutting. This leads to excessive gaps in the closure, requiring welding repairs and resulting in secondary or multiple repositioning steps, impacting construction efficiency and product quality. Furthermore, this construction method is complex, requires significant manpower, and necessitates workers climbing scaffolding, posing a high safety risk. Therefore, accurately and quickly determining the cutting allowance lines while meeting the requirements of the construction drawings has become an urgent problem to be solved. Utility Model Content

[0005] To achieve accurate and rapid determination of cutting allowance lines, this invention provides a device for marking allowance lines in ship sectioning. The device uses a positioning pointer to indicate the cutting allowance value on a scale. The position of the marking pointer is adjusted, and then the positioning bolt is tightened with a fastening nut to fix the pointer's position. After the upright plate is vertically attached to the clean material section, pulleys move the device along the allowance section, and the marking pointer is used to draw the allowance line. This solves the technical problem of inaccurately determining cutting allowance lines using traditional methods.

[0006] The solution adopted by this utility model to solve the technical problem is:

[0007] A device for marking allowance lines for ship sections includes a graduated platform horizontally positioned above the allowance section, with a through groove parallel to its long side inside, and a scale parallel to the through groove fixed to its upper surface; a vertical plate fixed to the lower part of the graduated platform, arranged vertically against the finished material section; a pulley fixed to the lower part of the graduated platform to maintain its balanced arrangement; a positioning bolt assembled in the through groove, with its bottom end extending towards the allowance section; a fastening nut located at the lower part of the graduated platform and fastened to the positioning bolt; a marking pointer fixed to the bottom end of the positioning bolt, with its tip pointing downwards to contact the allowance section and marking the allowance line on its surface; and a positioning pointer fixed to the head side wall of the positioning bolt, always pointing towards the scale.

[0008] The marking pointer disclosed in this embodiment adopts a spiral telescopic structure, which extends to different lengths to adapt to marking the margin line on the margin segment with different strengths.

[0009] Positive effects:

[0010] This invention features a graduated platform on the allowance section. A mounting plate and pulleys are fixed to the lower part of the platform. Positioning bolts and fastening nuts are installed inside the platform. A marking pointer is fixed to the bottom of the positioning bolt, and a positioning pointer is fixed to the side wall of the bolt's head. By pointing the positioning pointer to the determined allowance cutting value, the position of the marking pointer is adjusted, and the positioning bolt is tightened with the fastening nut to fix the pointer's position. After the mounting plate is perpendicular to the finished material section, the pulleys move the device along the allowance section, and the marking pointer is used to draw the allowance line, achieving accurate and rapid positioning of the cutting allowance line. This device is simple and convenient to operate, easy to disassemble and maintain. Using only this device, the marking of the allowance line can be completed independently, effectively improving construction efficiency and quality, and avoiding the risks of line deviation and repeated positioning associated with traditional methods. It is suitable for use as a device for marking allowance lines in ship sections. Attached Figure Description
