The invention discloses a probe detector for detecting transverse defects in a rail head. The probe detector is arranged on a detection frame, and comprises a wear-resistant block at the lower portion and a probe box at the upper portion, wherein one side of the probe box is provided with a plurality of mounting grooves, the mounting grooves are provided with fixing keys, a water inlet hole, a plurality of BD probe holes and a plurality of transverse wave probe holes are sequentially formed in the upper surface of the probe box in a penetrating mode, and a water inlet pipe, BD probes and transverse wave probes are installed on the water inlet hole, the BD probe holes and the transverse wave probe holes respectively. According to the invention, the BD probes of the probe detector are arranged in the shape of a Chinese character pin instead of being arranged in a linear mode, two transverse wave probes are additionally arranged, arranged in the longitudinal direction of the steel rail and used for detecting transverse defects in the rail head, and it needs to be guaranteed that the flaw detection area of the rail head is larger than or equal to 70%.
本发明公开了一种用于检测轨头内部的横向缺陷的探头检测器,它探头检测器设置在检测架上,它包括下部的耐磨块和上部的探头盒,所述探头盒一侧开设有多个安装槽,所述安装槽上设置有固定键;所述探头盒上表面依次贯通有进水孔、多个BD探头孔和多个横波探头孔,所述进水孔、BD探头孔和横波探头孔上分别安装有进水管、BD探头和横波探头。本发明探头检测器的BD探头“一”字型布置改为“品”字型布置,并新增两个横波探头,沿着钢轨纵向布置,用于检测轨头内部的横向缺陷,且需保证轨头的探伤面积≥70%。
