Description

Technical Field

[0001] The invention relates to the technical field of length measuring equipment, in particular to a length measuring equipment for nuclear power stainless steel materials which is easy to operate. Background Art

[0002] Against the backdrop of continuous optimization of today's energy structure, nuclear power, as a clean, efficient and stable energy source, has become increasingly prominent. As the global demand for clean energy continues to rise, the scale of nuclear power plant construction is also continuing to expand. Stainless steel materials, with their excellent corrosion resistance, high temperature resistance, excellent weldability and outstanding radiation resistance, play an extremely critical role in the nuclear power field and are widely used in various systems and components of nuclear power plants. During the construction and operation of nuclear power plants, there are extremely stringent requirements on the performance of various materials, especially in extremely harsh environments such as high temperature, high pressure and strong radiation. Materials must have excellent comprehensive performance to ensure the safe and stable operation of nuclear power plants. Length measurement has an impact on the processing and use of nuclear power stainless steel materials that cannot be ignored. In 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. In order to facilitate the accuracy of nuclear power stainless steel materials, a length measurement device is required.

[0003] Traditional length measuring equipment is generally based on the principle of linear measurement and realizes dimensional measurement through linear displacement acquisition. However, the stainless steel materials in nuclear power projects often present complex spatial forms due to the needs of modular splicing and special-shaped component manufacturing. Linear measuring equipment is limited to a one-way measurement path and it is difficult to fully capture non-linear contours, resulting in low measurement adaptability. At the same time, at the operational implementation level, traditional stretching ruler tools rely on manual pulling for positioning and reading recording. When facing large-scale components, multiple people need to work together, which has high manpower investment costs and is prone to measurement inaccuracies due to errors in personnel coordination. In addition, during the stretching process, uneven force and measurement reference offset are prone to errors in the measurement data. Summary of the Invention
