[0002] Pressure pipelines are tubular devices used to transport gases or liquids. They are designed and constructed to withstand fluid transmission under high pressure conditions. When pressure pipelines are used or maintained, a wall thickness gauge is needed to measure the pipe wall thickness.

[0003] However, existing pipe wall thickness measuring instruments can only measure one part of the pipe at a time. When multiple parts need to be measured and data recorded, the position of the measuring instrument needs to be adjusted repeatedly, which is time-consuming and results in low measurement efficiency. Therefore, there is an urgent need for a portable pressure pipe wall thickness measuring instrument to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable pressure pipe wall thickness measuring instrument to solve the problem mentioned in the background art, which requires repeated adjustment of the measuring instrument's position when multiple parts need to be measured, resulting in low measurement efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable pressure pipeline wall thickness measuring instrument, comprising a pipeline body and a scale, wherein a central column is provided on one side of the pipeline body, and a fixed measuring plate is snapped onto the outer surface of the central column, wherein there are two fixed measuring plates, symmetrically distributed on the upper and lower sides of the central column, and a square plate is fixedly connected to the outer surface of the fixed measuring plate; and a sliding measuring plate is slidably connected to the outer surface of the pipeline body, wherein there are two sliding measuring plates, distributed on the left and right sides of the central column;

[0006] The fixed measuring plate has a slider internally connected to it, the outer surface of the fixed measuring plate is fixedly connected to the outer surface of the scale, and the outer surface of the sliding measuring plate is fixedly connected to the outer surface of the scale.

[0007] The outer surface of the square plate is threaded with a threaded rod, and the bottom end of the threaded rod is connected to a circular plate. The bottom surface of the circular plate is slidably connected to the outer surface of the pipe body.

[0011] The inner wall of the arc-shaped groove is provided with a limiting groove, and the side of the sliding plate is fixedly connected to a limiting plate. The outer surface of the limiting plate is slidably connected to the inner wall of the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model discloses a portable pressure pipe wall thickness measuring instrument. Through the cooperation between the pipe body, the fixed measuring plate and the sliding measuring plate, and the fixing of the pipe body by the upper and lower threaded rods, the wall thickness of the pipe body can be measured by moving the slider up to a position close to the inner wall of the pipe body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a portable pressure pipeline wall thickness measuring instrument, including a pipeline body 1 and a scale 2. A central column 3 is provided on one side of the pipeline body 1. A fixed measuring plate 4 is snapped onto the outer surface of the central column 3. There are two fixed measuring plates 4, which are symmetrically distributed on the upper and lower sides of the central column 3. The fixed measuring plates 4 can measure the wall thickness of two symmetrically distributed parts in the pipeline body 1. Two parts can be measured at one time. After measuring the two positions of the pipeline body 1, the fixed measuring plates 4 cannot be moved.

[0023] The outer surface of the central column 3 is provided with a groove 10, and the bottom surface of the fixed measuring plate 4 is connected to a concave plate 11. The outer surface of the concave plate 11 is slidably connected to the inner wall of the groove 10. The fixed measuring plate 4 can be installed by clamping the concave plate 11 into the inner wall of the groove 10. When carrying and packing the device, the concave plate 11 needs to be slid out of the groove 10 and the two fixed measuring plates 4 need to be removed for easy carrying.

[0024] A square plate 7 is fixedly connected to the outer surface of the fixed measuring plate 4, and a sliding measuring plate 5 is slidably connected to the outer surface of the pipe body 1. There are two sliding measuring plates 5, which are symmetrically distributed on the upper and lower sides of the central column 3. The sliding measuring plate 5 can measure the wall thickness at different positions. The measurement principle of the sliding measuring plate 5 is the same as that of the fixed measuring plate 4. The difference is that the sliding measuring plate 5 can be changed in position to obtain more wall thickness data.

[0025] An arc-shaped groove 13 is provided on the outer surface of the central column 3. A sliding plate 14 is fixedly connected to one end of the sliding measuring plate 5. The outer surface of the sliding plate 14 is slidably connected to the inner wall of the arc-shaped groove 13. When it is necessary to change the position to measure its wall thickness, simply rotate the sliding measuring plate 5. At this time, the sliding plate 14 will slide on the inner wall of the arc-shaped groove 13. After measuring two positions of the pipe body 1, the sliding measuring plate 5 can be moved to other positions for measurement.

[0026] A limiting groove 15 is provided on the inner wall of the arc groove 13, and a limiting plate 16 is fixedly connected to the side of the sliding plate 14. The outer surface of the limiting plate 16 is slidably connected to the inner wall of the limiting groove 15. When the sliding plate 14 slides on the inner wall of the arc groove 13, the limiting plate 16 will slide on the inner wall of the limiting groove 15. The setting of the limiting plate 16 can prevent the sliding plate 14 from detaching from the arc groove 13 and has a limiting effect on the sliding plate 14.

[0027] The fixed measuring plate 4 has a slider 6 internally connected to it. The outer surface of the fixed measuring plate 4 is fixedly connected to the outer surface of the scale 2. The outer surface of the sliding measuring plate 5 is fixedly connected to the outer surface of the scale 2. The outer surfaces of both the sliding measuring plate 5 and the fixed measuring plate 4 are provided with scales 2. The part of the slider 6 that contacts the pipe body 1 is arc-shaped, which facilitates fitting with the inner wall of the pipe body 1 and reduces errors. The outer surface of the fixed measuring plate 4 is provided with a groove 12. The inner wall of the groove 12 is slidably connected to the outer surface of the slider 6. The slider 6 is stuck in the inner wall of the groove 12 and can slide up and down on the inner wall of the groove 12.

[0028] The outer surface of the square plate 7 is threaded with a threaded rod 8, and the bottom end of the threaded rod 8 is connected to a circular plate 9. The bottom surface of the circular plate 9 is slidably connected to the outer surface of the pipe body 1.

[0029] Working principle: With the central column 3 positioned at the center of the pipe body 1, rotating the upper and lower threaded rods 8 causes the upper and lower circular plates 9 to move closer together, pressing and fixing the outer surface of the pipe body 1. Moving the slider 6 up to a position close to the inner wall of the pipe body 1, aligning the bottom surface of the circular plate 9 with the scale 2 and taking a reading of L1, and then aligning the upper surface of the slider 6 with the scale 2 and taking a reading of L2, the wall thickness can be calculated: Wall thickness = L2 - L1. When it is necessary to change the position to measure the wall thickness, simply rotate the sliding measuring plate 5. At this time, the sliding plate 14 will slide on the inner wall of the arc groove 13, and the limiting plate 16 will slide on the inner wall of the limiting groove 15. The sliding measuring plate 5 can be rotated to the part to be measured. Then, rotating the threaded rod 8 brings the circular plate 9 into contact with the outer surface of the pipe body 1, and then sliding the slider 6 to a position close to the inner wall of the pipe body 1. This facilitates the detection of different parts and the acquisition of more data.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
