The invention relates to the field of track flaw detection, in particular to a sliding shoe type steel rail flaw detection mechanism and a sliding shoe type steel rail flaw detection trolley, and the sliding shoe type steel rail flaw detection mechanism comprises a mounting frame, a bracket, depended wheels and a flaw detection mechanism; the support is parallel to the length direction of the steel rail and slidably connected to the mounting frame, and the support can move on the mounting frame in the length direction perpendicular to the steel rail. The at least two depended wheels are sequentially mounted on the bracket along the length direction of the steel rail; the flaw detection mechanism is slidably connected to the mounting frame and can move on the mounting frame in the length direction perpendicular to the steel rail; and the flaw detection mechanism comprises a plurality of probes. Compared with an existing wheel type flaw detection mode, the sliding shoe type steel rail flaw detection mechanism has the advantages that the flaw detection effect is better, all the probes can work at the same time, and theoretically, under the same sampling interval, the highest detection speed can be increased by 30% or above and reaches 20 km/h or above compared with that of a wheel type detection mechanism.
本发明涉及轨道探伤领域,具体涉及到一种滑靴式钢轨探伤机构和一种滑靴式钢轨探伤小车,其中一种滑靴式钢轨探伤机构包括安装架、支架、靠轮和探伤机构;支架平行钢轨的长度方向设置并滑动连接于安装架上,支架可在安装架上沿垂直钢轨的长度方向移动;至少两个靠轮沿钢轨的长度方向依次安装在支架上;探伤机构滑动连接于安装架上并可在安装架上沿垂直钢轨的长度方向移动;所述探伤机构包括多个探头。本发明对比现有的轮式探伤方式对伤损的检测效果更好,采用此滑靴式钢轨探伤机构,所有探头可以同时工作,理论上在同样的采样间距下比轮式检测机构最高检测速度可提升30%以上,达到20km/h以上。
