Description

TECHNICAL FIELD

[0001] The utility model relates to rail performance test technical field, especially a kind of steel rail weld triangle area 360 ° rotary scanning device. BACKGROUND

[0002] Under the background of the rapid development of railway transportation industry, as an important component of railway track, the safety and reliability of steel rail are directly related to the operation safety of train. However, the weld formed in the welding process of steel rail, especially the weld triangle area, becomes a weak link in the track structure due to its complex geometry and special stress state. Although the existing steel rail weld detection device and technology can meet the conventional detection requirements to some extent, there are still obvious deficiencies in the comprehensive scanning and high-precision detection of weld triangle area.

[0003] Specifically, some steel rail weld detection devices on the market currently use multi-axis moving components and rotating mechanisms to drive ultrasonic probes for scanning. However, due to the limited range of rotational scanning, they cannot achieve 360 ° omnidirectional coverage detection of the weld triangle area, resulting in some areas becoming blind spots. At the same time, these devices often rely on multiple independent components to work together, with complex structure, which not only increases the difficulty and cost of equipment maintenance, but also may have the problem of inaccurate positioning when facing complex working conditions, affecting detection efficiency and reliability.

[0004] In addition, although some steel rail weld identification systems can use acoustic sensors and coupling media to achieve automatic identification and positioning of welds, and optimize detection data through a data correction unit, they mainly focus on identification and data correction of weld position, and lack comprehensive scanning capability for complex geometry of weld triangle area. In addition, its detection method is limited to a single direction of acoustic wave propagation path, which is difficult to adapt to the complex three-dimensional structure detection requirements of weld triangle area, thereby reducing the overall detection accuracy and reliability.
