Description

Technical Field

[0001] This utility model relates to the field of ship surveying tools, and more specifically, to a piping system on-site layout drawing ruler. Background Technology

[0002] A Chinese patent, titled "A Linear Layout Ruler" with application number 202020819858.1, describes a structure comprising a laterally extending and adjustable telescopic main tube. A handrail is connected to the top of the main tube, and a steering pulley is connected to the bottom. A dust-spreading funnel and a support structure are connected to the left and right ends of the main tube, respectively. The dust-spreading funnel is placed vertically, with its bottom slightly higher than the steering pulley. The support structure includes a support tube on the same horizontal plane as and perpendicular to the main tube, and at least three identical wheels mounted on the outside of the support tube. The support structure also includes a bracket connecting the support tube and the main tube. A steering pulley is also connected below the bracket. The bracket, the main tube, and the support tube form a right-angled triangle. The handrail includes a gripping rod parallel to the main tube and at least two vertical connecting rods perpendicularly connecting the gripping rod and the main tube. The main tube is divided into three sections, each connected by bolts. The telescopic main tube has a maximum extension length of 25m, the steering pulley diameter ranges from 35cm, and the guide wheel diameter ranges from 24cm. The gripping rod length ranges from 0.83m, and the vertical connecting rod length ranges from 11.5m. Although this tool is a ruler and can determine the layout, it cannot be applied in the shipbuilding field. When laying out on a ship repair site, construction workers need to draw the layout of the piping system before going to the site for material cutting, pipe bending, and fabrication. Construction workers draw by hand on site, resulting in inconsistent shapes and sizes, and a messy appearance. Sometimes, even the site workers cannot clearly see the shape and size of the drawing, especially when the drawing location has an incline or slope. This can easily lead to incorrect bending and inversion of the shape during pipe bending, affecting installation on the ship. Utility Model Content
