The invention relates to a railway track flaw detection mechanism and a flaw detection car, and belongs to the technical field of track flaw detection, the railway track flaw detection mechanism comprises a frame body, and further comprises a driving mechanism; a track detection mechanism; and a marking mechanism. Through cooperative use of the rail detecting mechanism and the marking mechanism, when flaw detection is performed on the upper surface of the rail, a polishing flaw detection belt moves on the upper surface of the rail, so that friction is generated between the polishing flaw detection belt and the upper surface of the rail, and when cracks and protrusions exist on the upper surface of the rail, the polishing flaw detection belt can move on the upper surface of the rail. At the moment, the friction force borne by the polishing flaw detection belt is increased when the polishing flaw detection belt passes through the cracks and the protrusions, then the marking mechanism works, marking liquid in the marking mechanism drips on the upper surface of the track through a marking pipe, and the track is marked; marking operation on the upper surface of the track is achieved through different friction forces when the upper surface of the track has defects, maintenance personnel can conveniently find the defects on the upper surface of the track in time, and the burden of the maintenance personnel is relieved.
本发明涉及一种铁路轨道探伤机构及探伤车,属于轨道探伤技术领域,该一种铁路轨道探伤机构,包括架体,还包括:驱动机构;探轨机构;标记机构。本发明通过探轨机构和标记机构的配合使用,在对轨道的上表面进行缺陷进行探伤时,将会使得打磨探伤带在轨道的上表面运动,使得打磨探伤带与轨道的上表面之间产生摩擦,而当轨道的上表面存在裂缝和凸起时,此时打磨探伤带在经过裂缝和凸起时受到的摩擦力将会增大,进而使得标记机构工作,使得标记机构内的标记液通过标记管滴落在轨道的上表面,对轨道进行标记,实现了利用轨道的上表面存在缺陷时摩擦力的不同对轨道上表面的标记操作,便于维修人员及时找到轨道上表面存在的缺陷,减轻了维修人员的负担。
