When the main pipe is ≥ DN80, CNC cutting is generally used. When the main pipe is ≤ DN32 and the branch pipe is ≤ DN10, direct drilling is generally used. For branches of other specifications, operators are required to draw the intersection line manually and cut manually. However, in the existing technology, the manual drawing of the intersection line is labor-intensive and the steps are cumbersome. The welding fit of some branch pipes is not high, which affects the welding efficiency and quality of the main pipe and branch pipe. Utility Model Content

[0027] A pipeline intersection line marking tool provided in an embodiment of the present application has a simple structure, is easy to operate, and is lightweight, and can be quickly installed on a workpiece to be measured. With the aid of the marking tool, the technical problems in the related art of manually drawing intersection lines, such as large workload and complicated steps, and low welding fit of some branch pipes, which affects the welding efficiency and quality of the main pipe and the branch pipe, can be improved.

[0028] Combination Figure 1 and Figure 2 The marking tool includes a plurality of telescopic components 100 and a plurality of connecting hinges 200. The plurality of telescopic components 100 are arranged at intervals, and the plurality of telescopic components 100 are combined to form a ring structure, and the inner wall of the ring structure can match the outer wall of the pipeline. It should be noted that the pipeline can be any pipeline, and in the process of manufacturing and installing the ship piping system, the pipeline is a branch pipe.

[0029] The telescopic assembly 100 includes an ink layer 130, a sleeve 110 and a telescopic rod 120 telescopically arranged in the sleeve 110. The ink layer 130 is arranged at one end of the telescopic rod 120, and a connecting hinge 200 is connected between each two adjacent sleeves 110, that is, adjacent telescopic assemblies 100 can rotate with each other, so that when the marking tool 1 is installed on the pipeline, it can be ensured that each telescopic assembly 100 is in contact with the outer wall of the pipeline to improve the accuracy of subsequent marking.

[0030] The present application provides a pipeline intersection line marking tool 1. During the manufacturing and installation of a ship piping system, the annular structure can be wrapped around the outer wall of the branch pipe, and then the branch pipe port is placed on the main pipe, and each telescopic rod 120 is slid so that the ink layer 130 of each telescopic rod 120 is attached to the outer surface of the main pipe, so as to leave a plurality of marking points on the outer surface of the main pipe, and the plurality of marking points are connected with a marker pen to complete the drawing of the intersection line on the main pipe; keep all the telescopic rods 120 as a whole stationary, and move the telescopic rods 120 as a whole to the end of the branch pipe, Use a marker to draw on the outer wall of the branch pipe along the shape of the end of the telescopic rod 120, which is the opening contour line that matches the intersection line on the main pipe. Since all the telescopic rods 120 are stationary as a whole during the process of moving from the outer surface of the main pipe to the end of the branch pipe, that is, the shape of the end of the marking tool 1 remains unchanged, the main pipe and the branch pipe can be matched after the holes are opened according to the intersection lines on the main pipe and the intersection lines on the branch pipe, thereby improving the welding quality of the main pipe and the branch pipe. The whole process is simple to operate, which greatly improves the welding efficiency of the main pipe and the branch pipe.

[0031] In some embodiments, since the telescopic rod 120 is slidably disposed in the sleeve 110, and all the telescopic rods 120 as a whole need to remain stationary in a short period of time when moving from the outer surface of the main pipe to the end of the branch pipe, a rough layer is provided on the outer surface of the telescopic rod 120 and / or the inner surface of the sleeve 110.

[0032] That is, the telescopic rod 120 may be provided with a rough layer, and the inner surface of the sleeve 110 may be provided with a rough layer, or the outer surface of the telescopic rod 120 and the inner surface of the sleeve 110 may be provided with a rough layer, thereby increasing the friction between the telescopic rod 120 and the sleeve 110, and improving the sliding damping of the telescopic rod 120, so that under the condition that no artificial force is applied to push the telescopic rod 120, the telescopic rod 120 and the sleeve 110 can remain stationary under the action of friction, so that the overall shape formed by all telescopic rods 120 remains unchanged during the process of moving from the outer surface of the main pipe to the end of the branch pipe, thereby ensuring that the intersection line on the branch pipe coincides with the intersection line on the main pipe, and improving the welding quality between the main pipe and the branch pipe.

[0033] In some embodiments, the rough layer is a frosted layer. The frosted layer has a relatively high roughness and can generate a relatively large friction force between the telescopic rod 120 and the sleeve 110 .

[0034] Of course, in other implementations, the rough layer may also be made of other materials with higher roughness, and this is not limited.

[0035] In some embodiments, in order to make the telescopic rod 120 move more smoothly, the telescopic assembly 100 includes two sleeves 110, and the two sleeves 110 are arranged at an interval, so as to strengthen the guiding effect on the movement of the telescopic rod 120 and prevent the telescopic rod 120 from tilting during the movement, resulting in inaccurate marking points.

[0036] In some embodiments, since when drawing the intersection line of the main pipe and the branch pipe, the main pipe is placed horizontally and the branch pipe is placed vertically, and the marking tool 1 is surrounded by the branch pipe, the marking tool 1 is also placed vertically, that is, the lower end of the telescopic rod 120 is attached to the main pipe. In order to avoid the telescopic rod 120 sliding during use, causing the upper end to be separated from the sleeve 110, thereby affecting the marking efficiency, a limit baffle is provided at the other end of the telescopic rod 120, and the projection of the limit baffle along its axis covers the sleeve 110. Therefore, under the limiting action of the limit baffle, the upper end of the telescopic rod 120 can be prevented from being separated from the sleeve 110.

[0037] In some embodiments, in order to reduce the contact area between the end of the telescopic rod 120 and the main pipe, improve the marking accuracy, and draw smooth and accurate intersecting lines, one end of the telescopic rod 120 has a marking point, the ink layer 130 is set at the marking point, and the interval between two adjacent marking points is less than 3 mm to ensure the accuracy of the intersecting lines.

[0038] In some embodiments, an arc-shaped structure is disposed at one end of the telescopic rod 120 , and the most convex point of the arc-shaped structure is configured as a line drawing point.

[0039] Of course, in other embodiments, one end of the telescopic rod 120 may also be a tip, and the end point of the tip is configured as a drawing point, which is not limited to this.

[0040] In some embodiments, a plurality of telescopic rods 120 may be arranged in parallel.

[0041] In some embodiments, the sleeve 110 is an aluminum alloy sleeve 110, and the telescopic rod 120 is an aluminum alloy telescopic rod 120. Aluminum alloy products have the advantages of light weight and high strength.

[0042] Next, the method for using the pipeline intersection line marking tool 1 provided in the embodiment of the present application is described:

[0043] 1) Place the scribing tool 1 around the branch pipe.

[0044] 2) Place the branch pipe port on the main pipe, and use a square to install the branch pipe to ensure that the branch pipe is perpendicular to the main pipe.

[0045] 3) Each telescopic rod 120 is longitudinally adjusted so that the end of each telescopic rod 120 is in close contact with the outer surface of the main pipe, and a marking point is printed on it through the ink layer 130 .

[0046] 4) Maintaining the overall shape of the multiple telescopic rods 120, the multiple telescopic rods 120 are moved as a whole to the end of the branch pipe.

[0047] 5) Use a marker to draw an intersection line on the outer surface of the branch pipe along the shape of the end of the telescopic rod 120.

[0048] 6) Use a marker pen to connect the marking points on the outer surface of the main pipe to complete the drawing of the main pipe intersection line.

[0049] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
