[Explanation] Due to the high altitude of the Qinghai-Tibet Plateau and the difficulty in controlling the quality of railway lines in winter, the construction season of Xining Public Works Machinery Section is from April to November every year.
Previously, all large-scale road maintenance machinery and equipment required annual centralized maintenance. Only after the maintenance of operation devices, inspection of circuits and hydraulic systems, inspection of axle damage, verification of brake valve parts, etc., could be carried out online.
Because the annual centralized repair of the maintenance workshop is carried out in the maintenance warehouse every year, the maintenance garage is also commonly known as the "big machine 4S shop".
[Same period] Wan Lihong, director of the second workshop of Qinghai-Tibet Group Corporation's Xining Engineering Machinery Section
Our annual maintenance difficulties, including technical difficulties, are the maintenance tasks every three years.
The task of frame repair is to overhaul the entire core travel system after erecting the main body, and then overhaul the bypass, including the bottom-mounted shock absorber and hydraulic shock absorber.
If the technical parameters of the core-moving system are not adjusted properly, it will cause a pulley at light level, and may be off-line if it is heavy.
[Explanation] In the maintenance warehouse, the employees of each workshop are grouping and dividing labor to maintain and inspect large-scale road maintenance machines and other equipment.
During the annual centralized maintenance period, in the face of large-scale machinery and equipment with complex structures, employees need to carry out at least six to eight hours of maintenance and inspection work every day to ensure that the road maintenance equipment can maintain normal operation in difficult and complex areas in the later period.
[Live sound] 416 (five channels 289) 291 (six channels 176) 175, well, these are normal, now you can go to work on site.
[Explanation] The operation scope of the Xining Public Works Machinery Section covers three places in Gansu, Qinghai and Tibet, with a working span of more than 2,000 kilometers, of which the construction section with an altitude of more than 4,500 meters has more than 1,300 kilometers and more than 400 construction workers.
In the past, employees needed to stay in high altitude areas for a long time all the year round, not only had to work under harsh weather conditions, but also had to live in a very difficult living environment when leaving the car.
In addition to playing chess and reading books, there is almost no other way of entertainment.
In the eight months out of the year, there are even fewer opportunities to go home to visit relatives.
[Same period] Ji Wenfang, director of the fourth workshop of the Qinghai-Tibet Group Corporation Xining Public Works Machinery Section
We are not talking about a fixed point (maintenance), when we are constructing, for example, from Xining to Lhasa, we have to walk to Lhasa one by one, step by step.
Therefore, the construction period is long, and the (natural) environment of the Qinghai-Tibet line itself is relatively poor. In addition, after going out, our employees' cultural life is relatively poor and information is blocked.
[Explanation] Now, in the camping car where the employees go out to work and live, they have been equipped with well-equipped fitness equipment and dining cars, and TV showers are readily available.
Now, when workers go out to work in high-altitude areas, they can also take hot baths and eat hot meals in this mobile "home" on time.
After work, employees can choose entertainment and exercise methods as needed, which not only enriches their spare time, but also ensures their physical and mental health under the condition of long-term travel.
[Live sound] Just follow what I just said, (action) grouping, a group of 12 movements, the interval (between groups) is about one minute, one group a day, plus you eat more, eggs and beef. Eat some, cooperate and come back this year, you will be a "macho", and the shape will come out, right?
In that case, my daughter-in-law was surprised when I went back.
[Explanation] Work and entertainment together constitute a complete life process. Work makes life meaningful, and entertainment makes life vivid and flesh-and-blood. The unity of opposites of the two runs through the development of the entire life.
The maintenance of large-scale machinery and equipment not only requires the support of profound professional theoretical knowledge, but also requires strong willpower to continuously work in high-altitude areas for a long time.
As for how to do a good job in difficult conditions, the employees of the mechanical engineering department said frankly that the secret lies in the inexhaustible source of hard work.
[Same period] Wan Lihong, director of the second workshop of Qinghai-Tibet Group Corporation's Xining Engineering Machinery Section
Originally, our entertainment was just playing poker and chess, but now it's good, now our equipment is good, we now have a shower car, and a gym, through the newly added equipment, it has enriched our spare time, only Only in this way can we ensure the safety of our construction and production after going out, and also ensure the efficiency of our construction.
[Explanation] After the centralized maintenance in April, the workers in the workshop are about to usher in a new round of online operations again.
The mobile "home" of the camper car will accompany the employees to cross the mountains and rivers of the plateau once again, and will also carry the motivation of the employees to work.
[Same period] Ji Wenfang, director of the fourth workshop of the Qinghai-Tibet Group Corporation Xining Public Works Machinery Section
We went to each station along the line and joined with each station area to carry out some good activities and related cultural and sports activities. Through these guarantees, we can solve everyone's worries. After the solution, everyone can devote their whole body and mind to safe production. .
