Ultrasonic Sensor Flaw Detector Operation Bid Farewell To Artificial To Smart

- May 02, 2018-

"After the dual track rail flaw detector (ultrasonic sensor) is put into use, the flaw detection worker can complete the rail flaw detection task for more than ten kilometers of lines within 120 minutes of the "skylight" time, which is three times the efficiency of manual hiking inspection." March 26, China Railway Zhengzhou For the first time, the Bureau of Nanyang Public Works Section of the Bureau Group Co., Ltd. used the “New Intelligent Detecting Assistant” to carry out a test on the 12 km line from the Ampang to the Huaiyuan region according to the Japanese plan.

Under normal circumstances, the "medical examination" of railway rails is based on small ultrasonic flaw detectors. It requires artificial walking to promote walking. It not only requires high professional skills and experience of the flaw detection workers, but also the physical strength of the operators. With the constant speeding of trains, the density of rail flaw detection increases, and the contradiction between the low efficiency of manual foot-detection operations, the period of rail flaw detection and the guarantee of equipment quality has become increasingly prominent.

The self-propelled system of the dual-track rail flaw detector is driven by a battery and can carry 4 operators working on the machine. The speed of the test can reach 15 km/h. In the flaw detection operation, it is possible to repeatedly inspect the suspicious parts of the rail damage. There are altogether 18 channels on the dual-track and two-probe, which can simultaneously detect the dual tracks and achieve full coverage of the rail head and rail waist. At the same time, the ultrasonic flaw detection system uses a custom chassis, using high-performance computers and high-brightness display screens for real-time monitoring, clear and intuitive, easy to identify, and facilitate the playback of job data analysis. As of April 13, double-track rail flaw detectors were tested on the line 16 times, and 145 kilometers of rail lines were detected. All kinds of hidden trouble problems were found in 17, and none of them leaked.
