Problems solved by technology
[0002] In the rail welding process, the existing flaw detection method of the rail weld is simple and rough, and the appearance of the weld is mainly observed manually
Since manual flaw detection is greatly affected by human factors such as personnel's technical level and sense of responsibility, problems such as missed detection and false reporting often occur, which makes the quality and efficiency of manual flaw detection low, seriously affecting the quality of flaw detection, resulting in rail failure. Quality stability is not high

Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0039] like figure 1 and figure 2 As shown, a rail weld flaw detection machine includes a frame structure body 1 , a primary motion system 2 , a secondary motion system 3 , a flaw detection mechanism 4 , a calibration track device 5 and a controller 6 .
[0040] like figure 1 and figure 2 As shown, the fuselage 1 includes two ground running frames 11 arranged in parallel, and two upper beam frames 12 perpendicular to the ground running frames 11 are horizontally arranged above the ground running frames 11. The upper beam frames 12 It is fixed to the ground running frame 11 through a plurality of columns 13 . Among them, the ground running frame 11, the upper beam frame 12 and the upright column 13 are tailor-welded with high-strength section steel to form the fuselage 1. The fuselage 1 provides a guarantee for the overall strength and ri...

The invention discloses a steel rail weld seam detection machine and method and relates to the technical field of steel rail detection. A detection machine body comprises two parallel ground traveling frames and two upper cross beam frames perpendicular to the ground traveling frames; a secondary motion system is arranged at the tops of the upper cross beam frames in a sliding manner and connected with a detection mechanism, and drives the detection mechanism to move along the ground traveling frames; a primary motion system is connected with the secondary motion system and drives the secondary motion system to move along the upper cross beam frames; a track check device is parallel to the ground traveling frames and fixed to stand columns; a controller is connected with the primary motion system, the secondary motion system, the detection mechanism and the track check device respectively and used for controlling the operation of each part. When the detection machine is used for detecting steel rail weld seams, the track check device is used for checking daily performance of the detection machine at first and then the detection mechanism is used for automatically scanning the weld seams; the whole detection process is full-automatic, the detection quality is good, and the working efficiency is high.
Description
technical field [0001] The invention relates to the technical field of rail detection, in particular to a rail weld seam flaw detector and a flaw detection method. Background technique [0002] In the rail welding process, the existing flaw detection method of the rail weld is simple and rough, and the appearance of the weld is mainly observed manually. Since manual flaw detection is greatly affected by human factors such as personnel's technical level and sense of responsibility, problems such as missed detection and false reporting often occur, which makes the quality and efficiency of manual flaw detection low, seriously affecting the quality of flaw detection, resulting in rail failure. Quality stability is not high. Contents of the invention [0003] Aiming at the defects existing in the prior art, the object of the present invention is to provide a rail weld flaw detector and a flaw detection method, which can realize the fully automatic operation of the flaw detect...
