Description

Technical Field

[0001] This utility model relates to the field of circular tube measurement technology, and in particular to a high-efficiency measuring device for measuring the curvature of a circular tube. Background Technology

[0002] A circular tube, also known as a circular pipe, is a closed annular tubular material with a hollow cross-section and a perimeter of uniform thickness and width. This material is widely used in engineering structures, mainly as a pipeline for the transmission of fluids such as water, oil, or natural gas. The curvature of a circular tube is closely related to its ability to resist compressive deformation. The smaller the diameter of the tube, the greater the curvature, and the greater the force projected onto the direction perpendicular to the diameter, thereby improving the strength and energy absorption capacity of the structure. Therefore, measuring the curvature of a circular tube helps to assess its stability and durability under stress.

[0003] In the traditional process of bending round tubes, it may be necessary to draw the expected shape of each round tube after bending on the ground, i.e., a "ground pattern". Then, the actual bent round tube is compared with this expected shape. This measurement method is quite troublesome in the process of drawing the ground pattern. It usually requires a variety of measurement auxiliary tools and is prone to inaccurate measurement data, which reduces the efficiency of measuring the curvature of the round tube. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency measuring device for measuring the curvature of a circular tube, comprising a square tube, wherein a measuring component is provided on the lower surface of the square tube;

[0006] The measuring assembly includes two end tubes and multiple middle tubes. The two end tubes and multiple middle tubes are fixedly connected to the lower surface of the square tube.

[0011] As a further description of the above technical solution:

[0018] One end of the stud is rotatably connected to a limiting block, and the upper surface of the limiting block is fixedly connected to a limiting rod, which is slidably connected inside the fixed sleeve.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model enhances the convenience of measuring the curvature of circular tubes by setting up a measuring component. It eliminates the need to draw the expected shape of each circular tube after bending, reducing the tedious step of drawing a "ground pattern" and thus omitting the step of combining the ground pattern.

The multiple middle placement tubes 3 are arranged between the two end placement tubes 2. A short ruler 4 is provided on one side of one end placement tube 2. A sliding groove 5 is opened on the upper surface of one end placement tube 2. A short screw 6 is rotatably connected inside one end placement tube 2. A driven bevel gear 7 is fixedly connected to one end of the short screw 6. A driving bevel gear 8 is rotatably connected to one side of the inner wall of one end placement tube 2. The driving bevel gear 8 and the driven bevel gear 7 are meshed. A first knob 9 is fixedly connected to the middle of the driving bevel gear 8 through a connecting shaft. The end placement tubes 2 are used to place the two ends of the round tube. The middle placement tubes 3 are used to place the middle part of the round tube. The short ruler 4 is used to adjust the distance between the first stop block 11 and the square tube 1 for measurement. The short screw 6 facilitates the movement of the first moving block 10, thereby moving the first stop block 11.

[0034] As attached Figure 4 As shown, the short screw 6 is externally threaded with a first moving block 10. The upper surface of the first moving block 10 is fixedly connected with a first stop block 11. The lower surface of the first stop block 11 is fixedly connected with a guide block 12. The guide block 12 is used to determine the moving position of the first stop block 11 with the assistance of the short ruler 4.

[0035] As attached Figure 3 As shown, a long ruler 13 is provided on the upper surface of the middle placement tube 3. A long screw 14 is rotatably connected inside the middle placement tube 3. A second moving block 15 is threadedly connected to the outside of the long screw 14. A connecting groove 16 is opened on one side of the middle placement tube 3. A second stop block 30 is fixedly connected to the upper surface of the other end placement tube 2. A connecting frame 17 is fixedly connected to one side of the second moving block 15. A measuring block 18 is fixedly connected to the upper surface of the connecting frame 17. A second knob 19 is fixedly connected to one end of the long screw 14 through a shaft. The long ruler 13 is used to determine the moving distance of the measuring block 18. The second moving block 15 is used to drive the measuring block 18 to move under the connecting action of the connecting frame 17, so as to get close to the curved surface of the circular tube.

[0036] As attached Figure 6 As shown, a limiting component is provided on the upper surface of the end placement tube 2. The limiting component includes a fixing plate 20, which is fixedly connected to one end of the upper surface of the end placement tube 2. A fixing rod 21 is fixedly connected to one side of the fixing plate 20. A sliding sleeve 22 is slidably connected to the outside of the fixing rod 21. A stud 27 is threadedly connected to the inside of the threaded hole. A limiting block 28 is rotatably connected to one end of the stud 27. A limiting rod 29 is fixedly connected to the upper surface of the limiting block 28. The limiting rod 29 is slidably connected inside the fixing sleeve 25. The sliding sleeve 22 is used to indirectly drive the position of the limiting block 28. Then, the position of the moving limiting block 28 is fixed with bolts 26.

[0037] As attached Figure 7 As shown, a threaded tube 23 is connected through the upper surface of the sliding sleeve 22, and a bolt 26 is connected to the internal thread of the threaded tube 23. An installation block 24 is fixedly connected to one side of the sliding sleeve 22, and a fixing sleeve 25 is fixedly connected to one side of the installation block 24. A threaded hole is opened in the middle of the installation block 24. The threaded tube 23 is fixed to the upper surface of the sliding sleeve 22 to facilitate the installation of the bolt 26. The fixing sleeve 25 is used to install the limiting rod 29, so that the limiting rod 29 limits the limiting block 28.

[0038] Working principle: When installing this utility model, the distance between the end placement tube 2 and the middle placement tube 3 is one meter, while the distance between the second stop block 30 and the square tube 1 is one hundred millimeters. In use, first, the round tube is placed horizontally above multiple end placement tubes 2 and multiple middle placement tubes 3, so that both ends of the round tube are placed above the two end placement tubes 2 respectively. Then, the two ends of the round tube are fixed using the limiting component. Next, the first stop block 11 is adjusted to a position one hundred millimeters away from the square tube 1. The first knob 9 is turned, which drives the driving bevel gear 8 to rotate. The driving bevel gear 8 drives the driven bevel gear 7 to rotate, and the driven bevel gear 7 drives the short screw 6 to rotate. Thus, the first moving block 10 slides inside the slide groove 5, bringing... The first stop block 11 is moved. Based on the pointing position of the pointing block 12 outside the short ruler 4, the moving position of the first stop block 11 is determined, and the first stop block 11 is adjusted to a position 100 mm away from the square tube 1. Then, the second knob 19 at the end where the tube 3 is placed in the middle is turned. The second knob 19 drives the long screw 14 to rotate under the connection of the shaft, so that the long screw 14 drives the second moving block 15 to move. The second moving block 15 drives the connecting frame 17 to move under the connection of the connecting groove 16, so that the connecting frame 17 drives the measuring block 18 to move on the surface of the long ruler 13. When the measuring block 18 moves to the side of the round tube and is close to it, the rotation stops. Then, the chord height is measured one by one with a tape measure, and the curvature of the round tube is checked against the drawing.

[0039] When fixing the round tube, first loosen the bolt 26 from the inside of the threaded tube 23, slide the sliding sleeve 22 to drive the limiting block 28 to the appropriate position, then tighten the bolt 26, and then turn the stud 27 so that the stud 27 rotates on the upper surface of the limiting block 28. Under the limiting action of the limiting rod 29 sliding inside the fixing sleeve 25, it drives the limiting block 28 to move towards the upper surface of the round tube. By pressing the upper surface of the round tube, the limiting and fixing effect is achieved.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
