Description

Technical Field

[0001] The utility model belongs to the technical field of building material sample detection, in particular to an auxiliary device for measuring the length of a sample in a ring stiffness test. Background Art

[0002] During a ring stiffness test, measurements of steel pipe specimens involve several key parameters to assess the material's stiffness and strength properties. The outer diameter of the pipe is measured using a caliper or micrometer. This provides the pipe's diameter, which is important for stiffness calculations. The pipe's wall thickness is measured using a micrometer or internal diameter gauge. Wall thickness measurement helps determine the pipe's cross-sectional area and stiffness. The pipe's length is measured using a gauge. This is important for defining the test section of the pipe. The pipe's circularity is assessed to ensure it is nearly perfectly round. This can be accomplished using optical measuring equipment or physical templates. Circularity is important for ensuring uniform stress distribution. The pipe is inspected for defects, cracks, dents, or deformation. Good surface quality is crucial for obtaining accurate test results. Vickers or Brinell hardness tests can be used to measure the material's hardness. This measurement provides information about the material's strength and toughness. In some cases, strain gauges can be used to measure strain on the pipe's surface during the ring stiffness test. These measurements can be used to calculate the actual strain and strain distribution in the material. Measuring these angles is crucial if the pipe has unusual angles or tapers. This is important for determining the geometric accuracy of the pipe. Measuring the weight of the pipe verifies its density and cross-sectional area, and verifies that the pipe meets the specified dimensional tolerances, including diameter tolerance, wall thickness tolerance, and length tolerance. These measurements provide important input parameters for the ring stiffness test, which can be used to calculate the stiffness, strength, and deformation characteristics of the material. Accurate measurements are essential for obtaining reliable and meaningful test results.

[0003] Measuring steel pipe specimens plays a crucial role in ring stiffness testing, providing critical data and ensuring accuracy. Here are some key uses for these measurements: By measuring the outer diameter, inner diameter, and wall thickness of the pipe, the actual dimensions of the pipe can be determined. These dimensions are important for calculating cross-sectional properties of the pipe, such as area moment and polar inertia, which are crucial for stiffness calculations. Measuring pipe dimensions also helps assess material properties, such as uniformity, thickness variation, and surface quality. These properties can affect the stiffness and overall performance of the pipe, and the measurement results are directly used to calculate the pipe's ring stiffness. Ring stiffness is a measure of a pipe's ability to resist bending and deformation. By combining the applied load with the pipe's deformation, a stiffness value can be calculated. By comparing the test results with design specifications and requirements, it is possible to verify that the pipe meets the expected performance standards. This is crucial for ensuring the structural integrity and stability of the pipe in real-world applications, and measuring pipe specimens can assist manufacturers and engineers in quality control. The quality and consistency of the production process can be evaluated by analyzing dimensional tolerances, material consistency, and any defects or anomalies. However, the above technology has the following problems: during the measurement of ring steel pipe samples, due to the different diameters of different samples, the auxiliary clamps used need to be adjusted differently. However, during the adjustment of the clamps, manual adjustments need to be made to the clamping ends. The adjustment process is relatively cumbersome and does not facilitate quick adjustments by the user. In addition, there is also the problem of being unable to clamp and measure irregularly shaped ring steel pipes. Utility Model Content

[0027] The working principle of this utility model:

[0028] When in use, the double-head telescopic motor 601 is started, and the output end of the double-head telescopic motor 601 will expand to both sides.
