Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline maintenance technology, and in particular to an auxiliary tool for pipeline marking. Background Technology
[0002] Pipelines are typically used for transporting oil. When a pipeline experiences a leak, rupture, or other emergency, oil transport must be suspended for repairs. This requires cutting off the damaged section and creating a new section of the corresponding length, which is then welded to the original section. When cutting the pipe section, a baseline must be drawn on the outer side of the pipeline. This not only provides a basis for calculating the length of the new section but also ensures the accuracy of the cutting position, guaranteeing that the cutting operation is performed along the predetermined and correct circumferential path, and preventing the cut from being tilted and affecting the welding of the new section.
[0003] In existing technologies, when marking lines on pipes, a strip of tape is usually placed around the point where the pipe is to be cut, and then a marking tool is used to mark the line around the pipe circumference along the edge of the tape. However, when using tape to assist in marking, multiple workers are usually required to work together. One worker holds and fixes the tape, another worker places the tape around the outer wall of the pipe, and finally another worker marks the line around the pipe circumference along the edge of the tape. This marking method not only increases labor costs but also has low work efficiency, and often affects production due to long maintenance time. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary tooling for pipe marking, which can reduce labor costs and labor intensity, improve work efficiency, reduce maintenance time, and avoid affecting the company's production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An auxiliary tooling for pipe marking is provided, comprising:
[0007] Reference component;
[0008] Two mounting bases are provided, each with a mounting groove. The two mounting bases are located on both sides of the reference member along the width direction, and the openings of the mounting grooves of the two mounting bases face each other. The first end of the reference member is respectively engaged in the mounting grooves of the two mounting bases along the width direction. The first end of the reference member is detachably connected to the mounting base. Each mounting base has a vertically formed connection hole at its top, and the connection hole communicates with the mounting groove.
[0009] A clamping assembly, the two ends of which are respectively engaged in the mounting grooves of the two mounting bases, and the clamping assembly is pressed on top of the reference member. The second end of the reference member can be arranged around the circumference of the pipe and pass through the bottom of the clamping assembly so that the reference member surrounds the outer wall of the pipe.
[0010] Two first fasteners are provided. The two first fasteners are respectively threaded into the connection holes of the two mounting bases and extend into the mounting grooves so that the first fasteners abut against the clamping assembly.
[0011] Optionally, the clamping assembly includes a clamping strip and a handrail. The two ends of the clamping strip are respectively engaged in the mounting grooves of the two mounting bases and stacked on top of the reference member. The length of the clamping strip is adjustable, and the handrail is disposed on the clamping strip.
[0012] Optionally, the auxiliary tooling for pipe marking further includes a limiting plug. The clamping strip includes a first clamping part and a second clamping part. The first end of the first clamping part is engaged in the mounting groove of any one of the mounting bases, and the second end is provided with a plurality of through holes I spaced apart along its extension direction. The first end of the second clamping part is engaged in the mounting groove of another mounting base, and the second end is provided with a plurality of through holes II spaced apart along its extension direction. The second end of the second clamping part overlaps with the second end of the first clamping part. The limiting plug is inserted into the through holes I and the through holes II.
[0013] Optionally, the auxiliary tooling for pipe marking further includes a second fastener, wherein the bottom of the mounting base has a mounting hole, and the second fastener passes through the reference piece and is threaded into the mounting hole.
[0014] Optionally, the second fastener includes a fastening bolt.
[0015] Optionally, the reference member is provided with scale portions on both sides along the width direction.
[0016] Optionally, the first fastener includes a wing bolt.
[0017] Optionally, the auxiliary tooling for pipe marking further includes an anti-slip component, which is disposed on the bottom wall of the mounting base, and the mounting base contacts the outer wall of the pipe through the anti-slip component.
[0018] Optionally, the anti-slip component includes anti-slip rubber.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides an auxiliary tooling for pipe marking, including a reference component, mounting bases, a clamping assembly, and first fasteners. When marking on the outer wall of a pipe, the two sides of the first end of the reference component are respectively engaged in the mounting grooves of the two mounting bases, and the two sides of the first end of the reference component are respectively connected to the two mounting bases. Then, the two ends of the clamping assembly are engaged in the mounting grooves of the two mounting bases and pressed on top of the reference component. The two first fasteners are respectively threaded into the connecting holes of the two mounting bases and inserted into the mounting grooves, so that the first fasteners press against the clamping assembly, thereby causing the clamping assembly to press the first end of the reference component. At this time, the clamping assembly, the two mounting bases, and the reference component are connected as one unit, and the operator can hold the mounting base by hand using the clamping assembly. Press the reference component onto the outer wall of the pipe, ensuring that the edge of the reference component is aligned with the position to be marked. Then, wrap the second end of the reference component around the circumference of the pipe once, and tighten the two first fasteners to create a small gap between the pressing assembly and the reference component. Then, pass the second end of the reference component through the gap between the pressing assembly and the reference component, and tighten the second end of the reference component so that the reference component surrounds the outer wall of the pipe. Then, tighten the two first fasteners again so that the first fasteners press against the pressing assembly, thereby pressing the pressing assembly onto the reference component. At this point, simply place the marking tool at the edge of the reference component and then mark the line on the pipe along the edge of the reference component.
[0021] By setting up a clamping assembly and a first fastener, the first end of the reference component is connected to the mounting base as one unit, and the first end is fixed to the mounting base. By tightening the first fastener, a gap is created between the clamping assembly and the first end of the reference component, which allows the second end of the reference component to pass through. Then, simply tighten the first fastener again to clamp the second end of the reference component. At this time, the reference component is wrapped around the outer wall of the pipe. A marking tool can be used to mark a line on the pipe along the edge of the reference component. The above marking process can be completed by only one worker, which can reduce labor costs and labor intensity, improve work efficiency, reduce maintenance time, and avoid affecting the company's production.

[0034] This embodiment provides an auxiliary tooling for pipe marking, such as... Figure 1 and Figure 2As shown, using this auxiliary tool for pipe marking can reduce labor costs and labor intensity, improve work efficiency, reduce maintenance time, and avoid affecting the company's production.
[0035] like Figure 1 and Figure 2 As shown, the auxiliary tooling for pipe marking includes a reference component 1, mounting bases 2, a clamping assembly 3, and a first fastener 4. Two mounting bases 2 are provided, each with a mounting groove 21. The two mounting bases 2 are positioned on opposite sides of the reference component 1 along its width, with the openings of their mounting grooves 21 facing each other. The first end of the reference component 1 is respectively engaged in the mounting grooves 21 of the two mounting bases 2 along its width, and the reference component 1 is detachably connected to the mounting bases 2. Each mounting base 2 has a vertically opening at its top, communicating with the mounting groove 21. Both ends of the clamping assembly 3 are respectively engaged in the mounting grooves 21 of the two mounting bases 2, and the clamping assembly 3 presses against the reference component 1. The second end of the reference component 1 can be wound around the circumference of the pipe and pass under the clamping assembly 3, so that the reference component 1 surrounds the outer wall of the pipe. There are two first fasteners 4. The two first fasteners 4 are screwed into the connection holes of the two mounting bases 2 and extend into the mounting grooves 21 so that the first fasteners 4 abut against the clamping assembly 3.
[0036] When it is necessary to mark lines on the outer wall of the pipe, the two sides of the first end of the reference piece 1 are respectively inserted into the mounting grooves 21 of the two mounting bases 2, and the two sides of the first end of the reference piece 1 are respectively connected to the two mounting bases 2. Then, the two ends of the clamping assembly 3 are inserted into the mounting grooves 21 of the two mounting bases 2 and pressed on top of the reference piece 1. The two first fasteners 4 are respectively threaded into the connecting holes of the two mounting bases 2 and inserted into the mounting grooves 21, so that the first fasteners 4 abut against the clamping assembly 3, thereby making the clamping assembly 3 press against the first end of the reference piece 1. At this time, the clamping assembly 3, the two mounting bases 2 and the reference piece 1 are connected as one unit. The operator can hold the clamping assembly 3 to press the reference piece 1 into place. The base 2 is pressed onto the outer wall of the pipe, ensuring that the edge of the reference part 1 is aligned with the position to be marked. Then, the second end of the reference part 1 is wrapped around the circumference of the pipe, and the two first fasteners 4 are tightened to create a small gap between the clamping assembly 3 and the reference part 1. Then, the second end of the reference part 1 is passed through the gap between the clamping assembly 3 and the reference part 1, and the second end of the reference part 1 is tightened so that the reference part 1 is surrounded on the outer wall of the pipe. Then, the two first fasteners 4 are tightened again so that the first fasteners 4 are pressed against the clamping assembly 3, thereby pressing the clamping assembly 3 onto the reference part 1. At this point, the marking tool is placed on the edge of the reference part 1, and then the line is marked on the pipe along the edge of the reference part 1.
[0037] By setting up the clamping component 3 and the first fastener 4, the first end of the reference part 1 is connected to the mounting base 2 as a whole, and the first end is fixed on the mounting base 2. By tightening the first fastener 4, a gap is created between the clamping component 3 and the first end of the reference part 1, which makes it easy for the second end of the reference part 1 to pass through. Then, simply tighten the first fastener 4 again to clamp the second end of the reference part 1. At this time, the reference part 1 is wrapped around the outer wall of the pipe. A scribing tool can be used to scribing a line on the pipe along the edge of the reference part 1. The above scribing process can be carried out by only one worker, which can reduce labor costs and labor intensity, improve work efficiency, reduce maintenance time, and avoid affecting the company's production.
[0038] For example, the first fastener 4 includes a wing bolt.
[0039] It should be noted that the width of reference piece 1 is the same as the axial length of the pipe section to be cut, and the two sides of reference piece 1 are respectively facing the two ends of the pipe section to be cut.
[0040] Optionally, such as Figure 1 and Figure 2 As shown, the clamping assembly 3 includes a clamping strip 31 and a handle 32. The two ends of the clamping strip 31 are respectively engaged in the mounting grooves 21 of the two mounting bases 2 and stacked on top of the reference piece 1. The length of the clamping strip 31 is adjustable. The handle 32 is provided on the clamping strip 31. When cutting a pipe, it is necessary to mark a line along the outer wall of the pipe. The required width of the reference piece 1 is determined according to the axial length of the pipe section to be cut, and then the line is marked on the pipe according to the marking method described above. By making the clamping strip 31 adjustable in length, the clamping assembly 3 can be used to clamp reference pieces 1 of different widths, making the entire auxiliary tooling more versatile. Furthermore, the handle 32 provides a base for the worker to hold the handle, facilitating the smooth execution of the marking work.
[0041] Optionally, the auxiliary tooling for pipe marking also includes a limiting insert, and the clamping strip 31 includes a first clamping part and a second clamping part. The first end of the first clamping part is engaged in the mounting groove 21 of any mounting base 2, and the second end has multiple through holes 1 spaced apart along its extension direction. The first end of the second clamping part is engaged in the mounting groove 21 of another mounting base 2, and the second end has multiple through holes 2 spaced apart along its extension direction. The second end of the second clamping part overlaps with the second end of the first clamping part, and the limiting insert is inserted into the through holes 1 and 2. When it is necessary to adjust the length of the clamping strip 31, simply adjust the length of the overlapping part of the first and second clamping parts according to the required length, and then insert the limiting insert into the corresponding through holes 1 and 2. The structure is simple and the operation is convenient.
[0042] like Figure 2As shown, the auxiliary tooling for pipe marking also includes a second fastener 5. The bottom of the mounting base 2 has a mounting hole, and the second fastener 5 passes through the reference piece 1 and is screwed into the mounting hole. When connecting the first end of the reference piece 1 and the mounting base 2, simply pass the second fastener 5 through the reference piece 1 and then screw it into the mounting hole. The structure is simple and the operation is convenient.
[0043] For example, the second fastener 5 includes a fastening bolt.
[0044] Optionally, the reference piece 1 has graduated portions on both sides along its width. When connecting the reference piece 1 and the mounting base 2, the two sides of the first end of the reference piece 1 are respectively engaged in the mounting grooves 21 of the two mounting bases 2, and the graduations on the two graduated portions facing each other on the edges of the two mounting bases 2 are the same. By setting the graduated portions, the edge of the reference piece 1 can be made perpendicular to the axis of the pipe, thereby ensuring that the scribing line is perpendicular to the axis of the pipe and ensuring the accuracy of the pipe cutting.
[0045] Optionally, the auxiliary tooling for pipe marking also includes an anti-slip component. The anti-slip component is located on the bottom wall of the mounting base 2, and the mounting base 2 contacts the outer wall of the pipe through the anti-slip component. By providing the anti-slip component, the friction between the mounting base 2 and the outer wall of the pipe can be increased, thereby ensuring that the reference component 1 can be stably mounted around the outer wall of the pipe, preventing the accuracy of the marking from being affected by the tilting or displacement of the mounting base 2.
[0046] For example, the anti-slip component includes anti-slip rubber.
[0047] Using the auxiliary tooling for pipe marking provided in this embodiment, lines are marked on the outer wall of the pipe. The marking process includes the following steps:
[0048] S1. The two sides of the first end of the reference piece 1 are respectively inserted into the mounting grooves 21 of the two mounting bases 2, and the two sides of the first end of the reference piece 1 are respectively connected to the two mounting bases 2.
[0049] S2. The two ends of the clamping component 3 are clamped in the mounting grooves 21 of the two mounting bases 2 and pressed on the top of the reference part 1. The two first fasteners 4 are screwed into the connecting holes of the two mounting bases 2 respectively, and the first fasteners 4 extend into the mounting grooves 21 so that the first fasteners 4 abut against the clamping component 3.
[0050] S3. Press the mounting base 2 onto the outer wall of the pipe and tighten the two first fasteners 4 to create a gap between the pressing assembly 3 and the reference piece 1.
[0051] S4. Wrap the second end of the reference piece 1 around the circumference of the pipe and pass through the gap between the clamping assembly 3 and the reference piece 1.
[0052] S5. Tighten the second end of the reference member 1 so that the reference member 1 surrounds the outer wall of the pipe, and tighten the two first fasteners 4 again so that the first fasteners 4 abut against the clamping assembly 3.
[0053] S6. Place the scribing tool on the edge of reference part 1 and scribing a line on the pipe along the edge of reference part 1.
[0054] By setting up the clamping component 3 and the first fastener 4, the first end of the reference part 1 is connected to the mounting base 2 as a whole, and the first end is fixed on the mounting base 2. By tightening the first fastener 4, a gap is created between the clamping component 3 and the first end of the reference part 1, which makes it easy for the second end of the reference part 1 to pass through. Then, simply tighten the first fastener 4 again to clamp the second end of the reference part 1. At this time, the reference part 1 is wrapped around the outer wall of the pipe. A scribing tool can be used to scribing a line on the pipe along the edge of the reference part 1. The above scribing process can be carried out by only one worker, which can reduce labor costs and labor intensity, improve work efficiency, reduce maintenance time, and avoid affecting the company's production.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
