Description

Technical Field

[0001] The invention relates to the field of industrial testing equipment, in particular to an integrated device for metallographic inspection and hardness testing of power station steam pipelines. Background Art

[0002] The steam pipeline of a power station will be affected by the high temperature and high pressure environment during long-term operation, and its metallographic structure and hardness characteristics will change, thus affecting the safety and service life of the pipeline. In order to ensure the reliable operation of the steam pipeline of the power station, the pipeline must be regularly inspected for metallographic and hardness. The integrated device for metallographic inspection and hardness testing of steam pipelines in power stations can perform metallographic inspection and hardness testing at the same time through an integrated design, providing an important basis for the status assessment of the pipeline, helping to timely discover potential problems of the pipeline and perform preventive maintenance.

[0003] The existing integrated metallographic inspection and hardness testing device for power station steam pipelines is usually carried out by employees using handheld tools. First, the operator needs to use handheld grinding equipment to process the pipeline surface to ensure the surface conditions for metallographic inspection, and then manually use a hardness tester to measure the hardness value of the pipeline. Although this handheld operation method is simple and intuitive, it requires high skills of the operator and is greatly affected by human factors. The test results of different operators may vary.

[0004] Although the existing integrated metallographic inspection and hardness testing devices for power station steam pipes can complete the final inspection work, there are still some shortcomings. First, most of these devices rely on manual adjustment and operation, and cannot realize automatic control of the position and angle of the detection device, resulting in frequent adjustments when facing pipelines of different specifications and complex states, which consumes a lot of time and energy and has low detection efficiency. Secondly, manual operation is easily affected by human factors, such as the experience and technical level of the operator, which makes it difficult to ensure the accuracy and consistency of the detection, especially when high-precision metallographic inspection and hardness measurement are required. This problem is particularly prominent. In addition, the grinding and connection components of the existing device are susceptible to wear and impact during operation, and lack effective elastic adjustment and protection measures, resulting in frequent replacement of parts and high maintenance costs, which affects the long-term stability and safety of the equipment. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an integrated device for metallographic inspection and hardness testing of power station steam pipes.
