Beijing North Railway Station mechanic——
Train "General Practitioner" to guarantee the Winter Olympics
Reporter Ding Yiting
Cloaked in "ice and snow blue" livery and embellished with white snowflakes, on January 21, the G8825 Winter Olympics train ran steadily on the Beijing-Zhang high-speed railway. "There are more than 2,700 monitoring points on the car, involving multiple states such as walking part, temperature, and air pressure, which can realize fault prediction and give operation and maintenance suggestions." In the monitoring cabin on the train, Jiang Nan, a mechanic accompanying the Beijing North Railway Station of the Beijing EMU section of China Railway Beijing Bureau Group Co., Ltd., stared at the four screens in front of him, paying attention to the real-time changes in the train data information.
The Beijing-Zhangzhou high-speed railway will provide transportation service guarantee for the Beijing Winter Olympic and Paralympic Winter Games this year, and the Beijing North Railway Station is the transportation inspection and maintenance base for the Beijing-Zhang high-speed rail operating EMUs. The 26 groups of Fuxing EMUs that Jiang Nan and his colleagues are on duty have a maximum operating speed of 350 kilometers per hour and a total mileage of more than 40,000 kilometers per day, which is equivalent to a circle around the earth's equator.
Faster speeds, more advanced models mean heavier responsibilities. The mechanic is like the "general practitioner" of the high-speed rail EMU, more than 2700 monitoring points, tens of thousands of fault codes, they must not only memorize the meaning of all the fault codes, but also master the corresponding processing methods to ensure the safe operation of the EMU.
"These codes are numbers, and without years of accumulation, it is easy to confuse and make accurate judgments in a timely manner." At the beginning, due to the lack of professional knowledge background, Jiang Nan was under a lot of pressure. Go to work with the teacher Fu familiar with the car body structure, discuss the fault, after work pestering the manufacturer technician to ask the principle, to the code, a full month to eat and live on the scene, he was stunned to eat the model a little bit through.
Beijing North Railway Station was opened in 2019, due to its special geographical location, there was a section of line with other stations without catenary in the early stage, and the EMU was returned to be pulled by organic vehicles. Once, heavy snow fell, and several groups of EMUs had to be returned. "The traction should be hung 6 times front and back, the transition hook weighs more than 50 pounds, and after a long time, I feel that my arms are about to 'dislocate'." From 6 p.m. to 4 a.m., Jiang Nan insisted, "Watching the trains of EMUs enter the warehouse smoothly, we have more confidence in running on the Beijing-Zhang high-speed railway to pursue our dreams." ”
With the Beijing Winter Olympics approaching, more and more people choose smart Beijing-Zhang travel, seat wireless charging, WiFi Internet access, intelligent lighting adjustment, Live Broadcast of Olympic Events and other services, so that passengers can enjoy a comfortable travel experience while feeling the "Speed of China".
"We want to help the Winter Olympics on the Beijing-Zhangjiang high-speed railway in the most full state and applaud China!" Inside and outside, Jiang Nan and more than 350 Winter Olympic train mechanics at the Beijing North Railway Station were busy again...
Baicheng Engineering Section Line Workshop Maintenance Worker——
Road and bridge "safety guard" is not afraid of wind, frost, rain and snow
Reporter Zheng Zhiwen
In the early morning, the temperature has dropped to minus 26 degrees Celsius, the cold wind whistles, and the maintenance workers of the Lijiayao line workshop of the Baicheng Engineering Section of China Railway Shenyang Bureau Group Co., Ltd. are ready to go to dunde Wusu Bridge for operation.
With a total length of 2108 meters and a height of 60 meters above the ground, the Xiwu (Xilinhot to Ulanhot) Railway, where the Dunde Wusu Bridge is located, is an important thermal coal transportation channel located in the central and eastern part of Inner Mongolia. More than 1,300 coal-loading trains pass through here each year, transporting more than 4.4 million tons of coal across the country.
"Due to the crushing of heavy-duty trains, the geometry of the Dundeusu Bridge line changes frequently. Therefore, regardless of wind, frost, rain and snow, we must maintain it regularly. Hou Feng, foreman of the Erlongtun Engineering District of the Lijiayao Line Workshop, joked that their work had to pass through three passes.
The first level, the wind. "Watch out for crosswinds, pay attention to safety." This was Hou Feng's first words every time he started his homework. The wind on the DundeWusu Bridge is above level 8 all year round, and it is often difficult to walk against the bone-chilling wind when working, and if you are not careful, you will fall. Loosening bolts and lifting roads, which are relatively easy to complete on flat ground, is much more difficult on the bridge.
The second level, extremely cold. The Siwu Railway crosses the steppe hinterland, where winters are cold and long, with temperatures as low as minus 40 degrees Celsius. After the Spring Festival began, the section ushered in a cooling weather, and the cold wind wrapped around the snowflakes and blew towards the maintenance workers. "The wind hits the face like a needle, making people unable to open their eyes." Hou Feng told reporters that although the cold is compelling, due to the large workload and high difficulty, after a while, beads of sweat will ooze from everyone's forehead.
The third level, fear of heights. "When I first got up to the bridge deck, my legs kept shaking and it took a long time to get used to it." The soft legs on the bridge are the common memories of many employees. New workers who have not been on the bridge in the work area must first accept psychological counseling to overcome their fear of heights.
Due to its deep grassland location, there are many blind spots in mobile phone signals. Even if you climb to the top of the mountain on both sides of the line, the mobile phone only has one signal, and the phone is intermittent when it barely passes. At night, the maintenance workers can only go to bed early to pass the lonely time.
Running up a thousand tons weighs, down to raise milliquine. "The standard is loose, and the risk when the train passes is increased by one point. The life of the line worker must be able to withstand the wind, frost, rain and snow of nature, survive the loneliness of the wild, and cultivate a pair of "fire eyes and golden eyes" to ensure the safety of the road and bridge. Hou Feng said.
Xiamen North Railway Station epidemic prevention and killing personnel——
Fine spraying and frequent disinfection to guard the epidemic prevention pass
Reporter Yan Ke
Pick up the sprayer, unscrew the nozzle, wave your arm, and the mist-like disinfectant sprays out in a fan shape... At 5:00 a.m. on January 18, through the empty waiting room of Xiamen North Railway Station, Wu Caiquan began a day of epidemic prevention and killing operations.
Wu Caiquan, 54, is an epidemic prevention and exterminator at Xiamen North Railway Station. Every day, he has to carry out all-round preventive killing in the 20,000-square-meter waiting room. The sprayer filled with disinfectant water weighs more than 20 kilograms, and 5 barrels of disinfectant water are used to kill in the waiting room, and the fastest time is more than 1 hour. During the Spring Festival, such preventive killings should be repeated every 4 hours.
Without taking a few steps, Wu Caiquan's forehead produced a fine circle of beads of sweat, and the exhaled water vapor passed through the gap of the N95 mask and condensed into a water mist inside the eye mask. Pure white medical protective clothing, N95 masks and goggles covered Wu Caiquan tightly.
In less than 15 minutes, a bucket full of disinfectant water has seen the bottom. After refilling the disinfectant water, Wu Caiquan looked up at the time on the electronic display and sped up. After the Start of the Spring Festival, the first train at Xiamen North Railway Station was moved forward by half an hour, which meant that Wu Caiquan had to complete the elimination of the passenger waiting area in a shorter period of time.
In addition to the physical test, the killing work must be particularly meticulous. In order to make the spraying of the potion more even, Wu Caiquan's pace and stride length should be as consistent as possible. With each step, the spray rod drew an arc, and a fine disinfectant potion covered every corner he walked. Wu Caiquan demanded himself: the corners and corners of the waiting room must be eliminated in place, and every floor and every garbage can should not be spared.
During the Spring Festival, the number of passengers in the waiting room increased significantly. In order to avoid spraying disinfectant on passengers' clothes and luggage, Wu Caiquan poured the disinfectant into the water tank of the driving scrubbing machine and saw stitches in the waiting room for disinfection. Railings, elevator handrails, ticket gates, which are key parts frequently touched by passengers, Wu Caiquan also repeatedly wiped and disinfected with a watering can and rag. At the end of the day, bend over tens of thousands of times, and the number of steps is as high as 40,000 or 50,000 steps.
At 12:30 p.m., after Wu Caiquan completed the second round of killing, he returned to the lounge, where his colleagues had already helped him warm up his meal. Taking off his protective clothing, taking off his blindfold and mask, Wu Caiquan sat down on a chair. "Kill a trip, the protective clothing can wring out 2 pounds of water." Wu Caiquan reached for the teacup, "Gollum Ando" poured two large mouthfuls of water, and then said to reporters, "Tired is not afraid at all, watching the passengers go home safely, the heart is solid." ”
Wuhan large-scale road maintenance machinery uses the maintenance section of the flaw detector team——
Do a "physical examination" of the rail to eliminate hidden dangers in operation
Reporter Wu Jun
At 22:00 on January 15, there were still 26 hours before the official start of the Spring Festival. A 44-meter-long steel rail flaw detection vehicle stopped at Suizhou South Railway Station in Hubei Province, brightly lit. The members of the first team of the Wuhan Large Road Maintenance Machinery Of China Railway Wuhan Bureau Group Co., Ltd. are preparing for the night flaw detection construction.
At 23:20, captain Guo Hongsong received the order to conduct flaw detection operations on nearly 160 kilometers of steel rails from Suizhou South to Hankou Station of the Hanshi high-speed railway within 210 minutes, "In order to ensure the safety of the Spring Festival line, we fought for more than 20 consecutive days, taking advantage of the opportunity of less high-speed rail traffic at night to conduct flaw detection on the Beijing-Guangzhou, Hanshi and other high-speed rail lines, timely discover the rail damage, and eliminate the hidden dangers of the line." ”
In front of the flaw detection operation table, data analysts Hu Xiaofu and Wu Huabin stared at the display screen. Damage inside the rails will be reflected in real time on the on-board computer display through markings of different colors and shapes. Flaw detectors should adjust the gain of the ultrasonic wave and the alignment of the detection wheel in time. "Any small negligence may cause rail leakage and leakage detection." Hu Xiaofu, who has 13 years of experience in flaw detection, does not dare to relax in the slightest.
At 2:50 a.m. on the 16th, the flaw detection work came to a temporary end, Guo Hongsong and his teammates could not take a break, continued to replay and analyze the data, and raced against time to feedback the test results to the public works section to eliminate hidden dangers as soon as possible.
Guo Hongsong told reporters that the flaw detector car they drove was the first all-vehicle nationally produced flaw detector car in China. Flaw detection vehicle borrows the principle of ultrasonic detection in the driving, not only fast speed, measurement accuracy is also very high, can effectively detect the internal damage of the rail and the state of the rail surface, even the naked eye can not see the millimeter-level cracks can also be detected, compared to the previous manual car flaw detection, the efficiency increased by nearly 30 times.
"Tomorrow is the first day of the Spring Festival, and tonight is the last time we will carry out night high-speed rail flaw detection before the Spring Festival." Next, the Pusu Railway will be flawed, and each line will be tested almost every other month. Guo Hongsong said.
The profession of rail flaw detector is very special, eating, living and working are in the same flaw detector car, 11 workers stay for more than 20 days, at least 11 months a year on this "mobile caravan", to the rail to do "physical examination".
In the 15 years since the 49-year-old Guo Hongsong entered the industry, he and his teammates have run all the railway lines under the management of the Wuhan Bureau, about 400,000 kilometers, achieving zero mistakes in safety detection for 11 consecutive years, providing a strong guarantee for the punctual operation and safe operation of the line.
