Description

Technical Field

[0001] This utility model belongs to the field of measuring instrument technology, specifically relating to a concave-convex deformation measuring instrument. Background Technology

[0002] Special equipment includes eight major categories such as boilers, pressure vessels, pressure pipelines, elevators, and lifting machinery. Special equipment is closely related to the safety of people's production and daily life. Its design, manufacture, use, repair, and modification are all subject to regulation, supervision, and periodic inspections. During operation, special equipment may develop defects such as bulges, dents, and swelling. These defects are usually caused by a variety of factors. First, improper operating conditions may lead to overload or uneven stress on the equipment, resulting in surface bulges or dents. For example, thermal expansion in high-temperature environments or uneven distribution of medium pressure can cause deformation of the equipment surface. Second, the quality of the materials themselves and the processing technology are crucial to the formation of surface defects. For example, insufficient heat treatment of materials or errors in the processing may cause swelling or dents on the equipment surface. Furthermore, the design structure and manufacturing quality of the equipment directly affect its pressure resistance and stability; unreasonable design or manufacturing defects may lead to bulges or dents on the equipment surface.

[0003] Accurate measurement and analysis are crucial for addressing these defects. High-precision measuring equipment can quickly and accurately detect and record bulges, dents, and swellings on equipment surfaces, helping operators identify problems promptly and take corrective action to ensure safe operation and long-term reliability. In-depth analysis of these defects in specialized equipment allows for optimization of material selection, processing techniques, and equipment design, thereby improving the equipment's pressure resistance and service life, ensuring stable operation under various working conditions.

[0004] For example, a bulge measuring instrument proposed in application number CN204694207U requires a guide rail to be fixed on the surface to be measured, and the support needs to be moved manually during the measurement process, which greatly affects the operation process and efficiency.

[0005] Application number CN216954323U proposes a bulge deformation dimension measuring instrument for pressure-bearing special equipment. However, it does not have the function of limiting the limit rod. When measuring the height of the bulge, if the operator's hand shakes while viewing the data, there will be errors in the measurement data.

[0006] Application number CN220366782U discloses a bulge deformation dimension measuring instrument for pressure-bearing special equipment. Its structure is relatively complex, requiring users to be familiar with the operation of each component. Limiting components may require a certain amount of force to operate, potentially affecting measurement efficiency. Accurate measurement of irregularly shaped bulges may be difficult.

[0007] Furthermore, the aforementioned defect measuring instruments in the existing technology require manual movement and visual readings, which are cumbersome to operate and lack accuracy. In actual use, human error can cause the location, height, or depth distribution of bulges or dents to deviate from the actual values.

[0008] Therefore, how to provide a high-precision and easy-to-operate concave-convex deformation measuring instrument has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0043] like Figure 5 As shown, the bulge height measuring unit 3 includes a bulge height measuring ruler 31, a bulge height measuring ruler connecting block 32, a bulge height measuring ruler sliding connecting block 33, a bulge height measuring ruler lever connecting block 34, a bulge height measuring ruler lever 35, a bulge height measuring ruler moving grid 36, a bulge height measuring ruler fixed grid mounting plate 37, a bulge height measuring ruler fixed grid 38, a bulge height measuring ruler guide rail 39, and a bulge height measuring ruler slider 310.

[0044] The bulge height measuring ruler guide rail 39 is fixed on the bulge height measuring unit guide rail fixing plate 17. The bulge height measuring ruler slider 310 is slidably limited on the bulge height measuring ruler guide rail 39. The bulge height measuring ruler sliding connecting block 33 is fixed on the bulge height measuring ruler slider 310.

[0047] It should be noted that each lever in this embodiment can be a fastening bolt that can adjust the slider stop.

[0048] The specific embodiments of this utility model are further described below:

[0049] like Figure 3 As shown, since the bulge outer diameter measuring lever module 27, the bulge outer diameter measuring gripper lever 26, the bulge outer diameter measuring unit sensor fixing plate 28, the bulge outer diameter measuring slider 22, and the pin 214 are fixedly connected together, the bulge outer diameter measuring slider 22 can be moved along the bulge outer diameter measuring guide rail 21 by moving the bulge outer diameter measuring lever module 27, thereby driving the pin 214 to move along the direction of the bulge outer diameter measuring guide rail 21. Due to the geometric relationship between the bulge outer diameter measuring fork linkage 29, bulge outer diameter measuring fork linkage 210, bulge outer diameter measuring jaw 211, and bulge outer diameter measuring jaw 212, the movement of pin 214 will cause the lowermost parts of bulge outer diameter measuring jaw 211 and bulge outer diameter measuring jaw 212 to open and close. When the opening and closing distance of the lowermost parts of bulge outer diameter measuring jaw 211 and bulge outer diameter measuring jaw 212 is exactly the size of the bulge outer diameter, the distance that pin 214 moves, that is, the distance that the bulge outer diameter measuring lever module 27 moves, can be determined by the geometric relationship between the mechanisms, thus measuring the size of the bulge outer diameter.

[0050] like Figure 9 As shown, pins 1 (214), 2 (215), 3 (216), and 4 (217) are positions A, B, C, and D respectively. The distances between A and B are L1, between A and C are L1, between B and D are L2, and between C and D are L2. The distances from position D to the bottom of jaw 1 (211) and from position D to the bottom of jaw 2 (212) are both L1.30 In the initial state of bulge height measurement, the distance between the lowest part of the bulge height measuring ruler 31 and the bulge outer diameter measuring jaw 211 is L. 40 The lowest part of jaw 211 (for measuring the outer diameter of the bulge) and the lowest part of jaw 212 (for measuring the outer diameter of the bulge) coincide, and the distance between AD is L5. Therefore, according to the law of cosines, we can obtain...

[0051]

[0052] When measuring the height of the bulge, the lowest part of the bulge outer diameter measuring jaw 211 and the lowest part of the bulge outer diameter measuring jaw 212 will measure the diameter of the bulge, while the bulge height measuring ruler 31 will move downward a distance L. 41 At the highest point of the bulge, the bulge outer diameter measuring lever module 27 will move downwards a distance L. 32 This causes the opening distance L6 between the lowest part of the bulge outer diameter measuring jaw 211 and the lowest part of the bulge outer diameter measuring jaw 212, which is the diameter of the bulge measuring ruler. Next, the downward movement distance L of the bulge outer diameter measuring lever module 27 is given. 32 The analysis process of the diameter L6 of the bulge measuring ruler. When measuring the bulge height, the bulge outer diameter measuring lever module 27 will move downward a distance L. 32 At that time, pin 214 at position A will also move downwards by a distance L. 32 The distance between AD is L5 - L 32 According to the Law of Cosines, we can obtain

[0053]

[0054] Therefore, we can obtain θ1 = θ - θ0.

[0055] This leads to L 31 =L 30 -L 30 cosθ1. The height of the bulge can then be calculated using the following formula.

[0056]

[0057] like Figure 10 As shown, when measuring the depth of the dent, the lowest part of the outer diameter measuring jaw 211 and the lowest part of the outer diameter measuring jaw 212 need to be opened so that the lowest part of the dent height measuring ruler 31 is placed on the top of the dent. At this time, the lowest part of the depth measuring rod 43 is brought into contact with the deepest part of the dent. The distance that the depth measuring rod 43 moves is the depth L of the dent. h .

[0058] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
