Embodiment Construction
[0019] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0020] This embodiment provides a technical solution: a separation and turning mechanism for the detection frame of a rail flaw detector, including a turning and returning structure, a lateral moving and returning structure, and the turning and returning structure includes a rotating shaft 41, a half The open shield 4 and the rail bottom ultrasonic probe 3 are mostly located inside the semi-open shield 4, and a small part leaks out of the semi-open shield 4 for flaw detection of the rail bottom. One end of the rotating shaft 41 is connected to the The semi-open shield 4 is fixedly connected, the other end passes th...

The invention discloses a separating and turning-up mechanism for a detection frame of a steel rail flaw detector, and belongs to the technical field of steel rail flaw detection, the separating and turning-up mechanism comprises a turning and returning structure and a transverse moving and returning structure, the turning and returning structure comprises a rotating shaft and a semi-open protective cover, one end of the rotating shaft is connected with the semi-open protective cover, the other end of the rotating shaft penetrates through the frame body and is movably connected with the frame body, a rail bottom ultrasonic probe is connected with the semi-open protective cover or the rotating shaft, the rail bottom ultrasonic probe and the semi-open type protective cover move synchronously, and the transverse moving and returning structure comprises a sleeving linkage rod, a rotating positioning seat and a driving linkage piece. According to the separating and turning-up mechanism for the detection frame body of the steel rail flaw detector, the ultrasonic probe at the rail bottom can be moved out more conveniently and lifted upwards to cross a sleeper below, the ultrasonic probe is prevented from colliding with the sleeper to be damaged, then normal detection work is guaranteed, the structure is relatively simple, the action efficiency is relatively high, and the detection efficiency is further improved.
Description
technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a separation and flipping mechanism for a detection frame of a rail flaw detector. Background technique [0002] Rail flaw detector, that is, rail flaw detection vehicle, can be divided into electromagnetic rail flaw detection vehicle and ultrasonic rail flaw detection vehicle according to the detection principle of rail flaw detection vehicle. The electromagnetic rail flaw detection vehicle detects rail damage based on the non-contact magnetic flux method. Ultrasonic rail flaw detection vehicle uses ultrasonic method for rail damage detection, which can detect fatigue defects and welding defects in the range of rail bottom and rail waist (including near joints), and some can also detect scratches, rail bottom crushing and Wavy wear, as well as rail bottom rust and crescent blocks. This vehicle is equipped with automatic recording equipment, which can record rail da...
