Technical Field
[0001] The utility model relates to the technical field of industrial detection equipment, in particular to a fixing device for steel pipeline weld detection equipment. Background Art
[0002] Steel pipelines are widely used in the oil, gas, chemical, and power industries. Welding is an essential process in the production and installation of steel pipes in these industries. However, the quality of pipeline welds is directly related to the safety and reliability of the pipelines. To ensure pipeline weld quality, effective weld inspection is essential. Traditional weld inspection methods rely on manual operation or manual adjustment of inspection equipment. While these methods can provide basic weld inspection, they suffer from low efficiency, poor stability, and high manual error.
[0003] With the continuous advancement of industrial automation, weld inspection equipment is gradually moving towards automation and intelligence. Ultrasonic flaw detectors and eddy current flaw detectors, currently the mainstream equipment in the weld inspection field, have been widely used due to their high precision and non-destructive nature. However, these devices place very strict requirements on the position and angle of the inspected object during inspection. Traditional equipment often cannot meet the requirements of precise fixing and position adjustment, resulting in unstable and inaccurate inspection results.
[0004] Therefore, developing a fixture that can precisely fix the weld seam of a steel pipe and flexibly adjust the equipment's position and angle is crucial to achieving both accuracy and efficiency in weld inspection. While some existing position adjustment devices exist, most simply adjust the device's position without comprehensively considering the relative position between the weld inspection equipment and the weld seam being inspected. This makes it impossible to ensure precise alignment of the inspection probe with the weld seam, impacting the accuracy of inspection results.
[0005] Therefore, designing a fixing device that can provide stable support and accurately adjust the relative position of the weld position and the detection equipment is of great significance for improving the accuracy, stability and detection efficiency of steel pipe weld detection equipment.
