The invention relates to the technical field of non-destructive testing, and provides a rapid steel rail ultrasonic testing probe, which comprises a transducer frame installed on a wheel shaft and located below the wheel shaft, and the lower end face, facing a steel rail, of the transducer frame is provided with two adjacent and symmetrical installation inclined planes; the transducer group is mounted on the transducer frame, the transducer group comprises a first transducer and a second transducer which are respectively arranged on the two mounting inclined surfaces, and the transducer group further comprises a third transducer arranged on the upper end surface of the transducer frame; the two flange plates are located on the two sides of the transducer frame respectively, and the two flange plates are rotationally connected to the wheel shaft in a sealed mode; the flexible outer film wraps the two flange plates, so that an in-wheel sealing space is formed between the two flange plates; and the sound blocking plate is arranged in the in-wheel sealed space, and one end of the sound blocking plate is installed on the transducer frame. The problem that the running speed of the rail flaw detection car cannot be effectively increased in the prior art can be solved.

    本发明涉及无损检测技术领域,提出一种快速钢轨超声波检测探头,其包括:换能器架,安装在轮轴上且位于轮轴的下方,换能器架朝向钢轨的下端面上具有相邻且呈对称设置的两个安装斜面;换能器组,安装在换能器架上,换能器组包括分别设在两个安装斜面上的第一换能器和第二换能器,换能器组还包括设在换能器架上端面上的第三换能器;两个法兰盘,分别位于换能器架的两侧,两个法兰盘均转动密封连接在轮轴上;柔性外膜,包覆在两个法兰盘的外部,以在两个法兰盘之间形成轮内密封空间;挡声板,设在轮内密封空间内,挡声板的一端安装在换能器架上。本发明能够解决现有技术中钢轨探伤车的运行速度不能得到有效提升的问题。
