The road of flaw detection of Hu Weiqin, the "railway detective" behind the Spring Festival.
Have you ever wondered how a train is kept safe when it is running on the tracks? Today, let's walk into the Shijiazhuang depot of China Railway Beijing Bureau Group and learn about the story of Wei Qin, a female axle flaw detection worker known as the "railway detective".
At 7 o'clock in the morning, when most people were still enjoying sleep, Hu Weiqin had already arrived at the Shijiazhuang depot parts workshop on time. Her job is to look for scars on the wheelset and make sure the train is running safely. This job sounds simple, but it actually requires a high level of responsibility and expertise.
Hu Weiqin has been engaged in flaw detection work for 20 years, and with her tenacity and meticulous work attitude, she has accumulated nearly 300,000 flaw detection wheelsets and found more than 40 various axle faults. Her work attitude and professional skills have been highly recognized by her colleagues, who call her "Railway Detective".
Before the formal flaw detection, Hu Weiqin will first conduct a "test" and input the artificial crack parameters into the flaw detector. This is a seemingly simple task, but it requires a high degree of precision. Because the probe is worn out every day, these parameters are re-entered before going to work each day.
There is a common process of flaw detection, and Hu Weiqin is responsible for manual ultrasonic flaw detection. It's a physical and mental job. She needs to bend down to input the information of the wheelset into the handheld terminal, then brush the couplant onto the wheelset with a brush, and then pick up the probe of the multi-channel sonde and slide it repeatedly at a fixed angle in a specific area of the shaft, while her eyes are engrossed in the waveform changes of the image on the sonde's screen.
Although the flaw detection work is hard, Hu Weiqin enjoys it. "I am very proud to think that the wheelset that I have tested by hand is safe on the railway," she says. This is the last Spring Festival in her work, and she will retire in October this year, so she is determined to stand on the last shift.
During this Spring Festival transportation period, let us pay tribute to railway workers like Hu Weiqin, who silently dedicate themselves to their posts and ensure our travel safety. At the same time, it also makes us think about how to better improve their working environment and treatment, so that they can enjoy the respect and rewards they deserve while serving the people.
