　　On the morning of January 16, a tall, thin young man was constantly measuring with a tape measure at the bottom of a railway freight car at the Guangbei Station of Guangzhou Railway Group’s Guangzhou North Railway Station.

Although it seemed a bit strenuous to work in a narrow place, it did not affect his concentration at work.

　　His name is Zhang Guangqi, and he is 33 years old this year. He is a vehicle fitter in the Guangbei Station Repair Team of the Guangbei Repair Workshop of the Guangzhou North Railway Station.

At this time, he is measuring whether the stroke of the piston rod of the brake cylinder of a railway freight car exceeds the limit.

　　The reporter learned that Zhang Guangqi has been working in this position for 3 years, and this year is his 10th Spring Festival travel season.

　　At 8:30 on the same day, Zhang Guangqi had just finished attending the team roll call meeting, and he pushed the bicycle tester to the 18th line of the maintenance depot without stopping, and quickly connected the air duct on the car to supply air to the railway freight vehicles.

With his right hand, he was operating various buttons on the bicycle tester, staring intently at the data on the pressure test gauge, and then measured the stroke of the brake cylinder to observe whether the brake cylinder was well relieved, and then carefully checked after each test The data.

In the past 3 years, he has never made any mistakes in his work in this position.

　　"The parking of railway freight cars mainly depends on the 120 brake control valve, which is like the 'heart' of railway freight cars. Once there is a slight detail in the work that is not checked in place, it will directly affect the driving safety of railway freight cars. Caused the 'brakes' of railway freight cars to fail." Zhang Guangqi said.

　　After checking the measurement and data, he brought a small bucket full of soapy water, and held a brush sticky with soapy water in his right hand, and applied soapy water to each joint to observe whether there were bubbles.

If there are air bubbles, the brake valve must be disassembled immediately.

　　Zhang Guangqi said that the principle of air brakes used by railway freight cars is different from that of automobile brakes. The so-called air brakes use compressed air as the power source and use changes in air pressure to control the brakes. Failure will greatly affect the braking performance and affect the safety of railway freight cars.

　　For this reason, one can imagine the importance of checking brake components, which also puts higher demands on Zhang Guangqi's work.

Especially during the Spring Festival travel season, he always tightened his strings. Through careful comparison and analysis of the data on the bicycle tester, he found potential problems in time, calmed down and dealt with them calmly, and then accurately "diagnosed" through manual tests. Tailor-made "treatment plan".

　　According to statistics, during the Spring Festival travel season, Zhang Guangqi discovered two typical failures of brakes, which prevented many potential safety hazards.

"We must work hard to ensure the safe operation of railway freight cars, and we must not be sloppy at all." Zhang Guangqi said confidently.

　　After working for many years, he has been conscientious and conscientious, and has never let a defective railway vehicle part "slip" from his hands.

"Our mission is to ensure that the 'heart' of every railway freight car is healthy." Zhang Guangqi said.
