Description

Technical Field

[0001] The present invention relates to the technical field of length measurement equipment, and particularly to a length measurement equipment for nuclear power stainless steel materials that is convenient to operate. Background Art

[0002] Under the background of the continuous optimization of the current energy structure, nuclear power, as a clean, efficient and stable energy source, has become increasingly prominent. With the continuous increase in the global demand for clean energy, the construction scale of nuclear power plants is also continuously expanding. Stainless steel materials play a crucial role in the nuclear power field due to their excellent corrosion resistance, high temperature resistance, good weldability and outstanding radiation resistance. They are widely used in various systems and components of nuclear power plants. During the construction and operation of nuclear power plants, extremely strict requirements are imposed on the performance of various materials. Especially in extremely harsh environments such as high temperature, high pressure and strong radiation, materials must possess excellent comprehensive performance to ensure the safe and stable operation of nuclear power plants. Length measurement has an important impact on the processing and use of nuclear power stainless steel materials. During the manufacturing process of nuclear power equipment, the processing accuracy of stainless steel materials is directly related to the performance and safety of the equipment. To facilitate maintaining the accuracy of nuclear power stainless steel materials, a length measurement equipment is therefore required.

[0003] Traditional length measurement equipment generally measures based on the principle of linear measurement, and realizes dimensional measurement through linear displacement acquisition. However, due to the requirements of modular splicing and the manufacturing of special-shaped components in nuclear power engineering, stainless steel materials often present complex spatial forms. Limited by the one-way measurement path, linear measurement equipment is difficult to completely capture non-linear contours, resulting in low measurement adaptability. At the same time, in terms of operation implementation, traditional stretching measuring tools rely on manual pulling for positioning and reading records. When facing large-sized components, multiple people need to cooperate, resulting in high labor input costs and easy measurement inaccuracies due to personnel cooperation errors. Moreover, during the stretching process, due to uneven force application and measurement reference deviation, measurement data errors are likely to occur. Summary of the Invention
