Yang Yongfeng, director of the inspection and maintenance workshop, came to the unit early in the morning to get busy. "The quality of the large aircraft directly affects the quality of the line, which is related to the travel safety of the vast number of passengers. This should not be careless." After July, the weather in Inner Mongolia is sultry and dry, and the temperature in the mechanical vehicle inspection and repair depot is more than 45 degrees. "The temperature in these days is too high, and the air in the maintenance shed is not ventilated. We will go outside to get some air after working." Yang Yongfeng said as he walked.
The foreman Zhou Qiang walked around the warehouse with a maintenance kit of nearly 10 kg. His team will complete the maintenance task of 11 large road maintenance machinery truck bogies in the near future. Drilling the trench and climbing the roof are the normal working conditions. The clothes and masks are soaked with sweat. "During the overhaul in summer, the number of steps per person in our work team is close to 30000."
If you want to carry out fine inspection and repair, you need to know well. Large-scale road maintenance machinery is different from ordinary passenger trains, with many parts, complex maintenance procedures and different faults. Before that, technicians checked the condition of mechanical equipment, checked the working status of 16 key parts of the mechanical vehicle operation, running, hydraulic and other systems one by one, and "customized" maintenance plan for each mechanical vehicle.
"We have made 'ID cards' for each mechanical vehicle, implemented the' one machine and one file 'maintenance system, and implemented the management mode of' who is responsible for the maintenance, who signs, who is responsible ', so that the division of responsibilities is clear at a glance, and the work efficiency has also been greatly improved," Yang Yongfeng said.
In the laboratory on the second floor of the maintenance base, a "oil sample test" group composed of women was also busy during this period. They are responsible for testing the hydraulic oil, engine oil and other oil samples of mechanical vehicles. These young laboratory technicians, with an average age of 30 years, will conduct 4152 tests on 2026 bottles of oil from 97 large road maintenance mechanical vehicles throughout the year.
"This work must not be sloppy. If our test results go wrong, the whole system of the mechanical car will be affected. We must be more careful." said Jia Bin, an oil sample analyst in the inspection and maintenance workshop.
It is understood that this summer's maintenance work began in the middle of July, and the large road maintenance machinery vehicles that passed the acceptance will immediately "rush" to the next operation site, continue to remove the "disease" of the line, improve the overall passenger and cargo transport capacity of the line, and escort passengers to travel safely.
