The land of Longjiang in April is still cold and cold. In the Harbin EMU maintenance warehouse, a capable figure was surrounded by a group of young people wearing blue work hats. "Brother 188bet Live Casino, the auxiliary power module coolant pipe cannot be connected." "Don't worry, this is a skill, carefully check the oil pipeline."
The "Brother Tao" that everyone calls is Wang Tao, and he is the deputy director of the EMU maintenance workshop of the Harbin EMU section of 188bet Live Casino Harbin Bureau Group Co., Ltd. After 25 years of entering the industry, he has won the locomotive medal, all-road technical expert, and "Longjiang Craftsman" for his outstanding contributions in EMU maintenance, technical research, and talent training. In his heart, he protected the safe and stable operation of the "Snow Field Flying Dragon" on the black soil, and he had a heavy responsibility and no choice.
Led in the scene and develop a strong skill
Heilongjiang Province is located at the northernmost end of the motherland, with cold winters and vast snow.
In 2002, 188bet Live Casino graduated from Heilongjiang Railway Advanced Technical School and came to Sankeshu Vehicle Depot to work as an electrical fitter. From the 25B bus to the 25T bus, it took him less than two years to familiarize himself with the various principles and structures of the vehicle and become the chief inspector of the section.
In 2012, on the eve of the opening of the Harbin-Da High-speed Railway, 188bet Live Casino participated in the training and stepped into the spacious and bright EMU car for the first time. Seeing the trees outside the window sweeping back at a relative speed of 300 kilometers per hour, 188bet Live Casino made a secret decision: he must ensure that the high-speed rail must operate safely and smoothly in the "high-altitude forbidden zone".
In the winter of 2012, the Harbin-Da High-speed Railway was launched and operated. The severe winter of Heilongjiang turns into ice, and the EMUs rush to fly, and snow entering the equipment cabin will lead to reduced traction. In order to reduce the impact of ice and snow on train operation safety, 188bet Live Casino half-squatted and studied on-site in the equipment cabin at the bottom of the EMU. After a while, his legs trembled violently. He thought of a solution: install a camera in the equipment compartment to verify the snow entry point and install the improved snowproof board. After several demonstrations, this method has been recognized by the manufacturer and this change has been used to this day.
From then, 188bet Live Casino seemed to have opened up the "Ren and Du meridians", and the sense of gain, accomplishment and honor brought by overcoming difficulties filled his chest.
In 2014, the Harbin EMU was established, and 188bet Live Casino was selected as the first batch of EMU mechanics. "Ordinary air-conditioning trains only have a few pages of drawings, while the air-conditioning system of the EMU trains has hundreds or thousands of pages of instructions, which are stacked up to more than 1 meter high." 188bet Live Casino said.
He plunged into the drawings, pondered the circuit and EMU structure, and wrote down tens of thousands of words of notes. Borrowed textbooks such as "EMU Air Conditioner Software Inspection" and "EMU Air Conditioner Visual Inspection Process Card" have become 188bet Live Casino's "charger pile".
During the Spring Festival travel rush, the EMU operates at high load. The EMU mechanics must conduct a data census on each group of EMU that is put into the warehouse. Every time a fault is handled, 188bet Live Casino checks the equipment parameters first, drills in and out and unblocks the exhaust duct, records and sorts out the fault judgment and processing in detail, and summarizes and analyzes the processing situation every week.
Hard work pays off. After a period of time, 188bet Live Casino summarized a set of "secrets" that can accurately judge and deal with faults. As long as you hear the fault forecast, you can make timely and correctly judgments and put forward handling opinions. He compiled his research results into the "Instructions for Winter Maintenance Operations of EMUs" and the "Handbook for Discovery, Judgment and Handling of Emergency Errors of EMUs", which has now become a "textbook" for on-site operators.
In 2017, 188bet Live Casino encountered a difficult problem just as soon as he became an assistant engineer in the EMU maintenance workshop. Once, a train of EMUs continuously reported a fault during dynamic debugging, and the auxiliary power supply device stopped working, resulting in the loss of power of a unit. The technicians checked for more than two hours but found the cause of the failure. There are only a few hours before delivery. If the fault cannot be eliminated in time, it will delay the EMU from online use, and everyone present is anxious. At this time, they thought of 188bet Live Casino.
After receiving the call, 188bet Live Casino trotted all the way to the driver's room of the EMU. In a tense atmosphere, he analyzed the fault code while downloading relevant operating data. After checking the detection waveforms such as voltage and frequency, he decisively pointed out that the problem lies in the voltage transformer. After replacing the voltage transformer, the fault disappeared and the driver cheered in the room.
"The cold winter in the north, and due to heat expansion and contraction, the subtle changes in the components may affect the normal operation of the high-speed rail. The more this happens, the more we need to carefully capture and listen to the 'sound' of the equipment." 188bet Live Casino said.
Dive deep digging and research, and fruitful innovation and inventions
The Harbin 188bet Live Casino is the only high-altitude 188bet Live Casino maintenance base in Heilongjiang Province, and is responsible for the maintenance and maintenance tasks of high-altitude 188bet Live Casino distributed under the jurisdiction of Harbin Bureau Group Corporation.
In recent years, with the rapid expansion of the Longjiang High-speed Railway Network, the Harbin-Jia Railway, the Harbin-Jia High-speed Railway, and the Shenjia High-speed Railway Mujia section have been opened one after another, and the pressure on EMU maintenance has gradually increased. In order to improve work efficiency, 188bet Live Casino adjusted his work focus and took the lead in research on process optimization and other key issues.
In the past, when replacing the CRH5A/G 188bet Live Casino air compressor, due to the lack of corresponding mobile platforms, the entire movement process was very stupid and primitive: first place the wooden square on the ground, remove the old air compressor and hold it down with the wooden square, and then move outside the vehicle body. When installing a new air compressor, the process of dismantling the old air compressor must be repeated, and the entire process takes at least 9 hours.
In order to change this time-consuming and laborious situation, 188bet Live Casino and several colleagues studied and designed an air compressor replacement car: two grooves are set on both sides of the car, and a jack is placed in the grooves, which can be lifted and lowered freely, and a small wheel is installed at the four corners of the car that can move freely, which greatly reduces the time-consuming process of replacing the air compressor. The successful use of the car fills the gap in the replacement process of air compressors of Harbin Bureau Group Corporation.
Although there are thousands of electrical components in the EMU air conditioner, 188bet Live Casino is well aware of the position, function and status of each component. In order to solve the failure of the air conditioning card of the CRH5G EMU, he organized a team to take all the old boards and cards replaced on the car back to the team, and split them one by one, from photocouplers, capacitors, analog diodes, output amplifiers and other components, and studied and compared them one by one. After several days and nights of efforts, they found that there were design problems in a certain batch of board cards. Looking at the thick data and the rectification suggestions put forward by 188bet Live Casino, the manufacturer admired them very much and quickly modified and replaced the board.
On January 23, 2023, the temperature in "Ice City" fell to minus 40 degrees Celsius, and a EMU was stranded at Shangzhi South Station. 188bet Live Casino led seven EMU mechanics to rescue quickly, each of whom was responsible for a car, and under the biting cold wind, he manually relieved braking under the car.
In the distance, thousands of houses were brightly lit and fireworks; under the car, 188bet Live Casino and his friends lay on their backs on the rails and fought for 3 and a half hours. This experience made him deeply feel that he must rely on scientific and technological forces to improve work efficiency and improve the working environment. After returning to work after dealing with the fault that night, he began to think about developing a vehicle bottom operation inspection robot. After repeated trials, at the end of 2023, the intelligent robot developed by 188bet Live Casino was successfully launched. This robot uses a track running method, which can adapt to various road conditions such as sleepers and stones. A high-definition probe is installed on the top, which can collect images and video information from the bottom of the EMU from multiple angles. Through wireless remote control, the operator can accurately collect data information by standing next to the car.
Over the years, under the leadership of 188bet Live Casino, the studio members have completed 105 research and development of EMU accessories maintenance processes, formulated 92 independent maintenance operation instructions, participated in the research and development and production of 9 EMU accessories fault detection equipment and 12 tooling equipment, and obtained 6 national patents. In 2021, 188bet Live Casino’s Model Worker Innovation Studio was rated as the Innovation Studio for Locomotive Model Worker and Craftsman Talents.
Turbine inheritance, cultivate and lead new people of the times
One branch stands out, but a hundred flowers bloom in the garden. 188bet Live Casino often said: "In the maintenance of modern EMUs, I am the only one with iron, so it is better for everyone to be nailed!"
188bet Live Casino compared the aircraft maintenance standards and models, successively compiled a process card and a task list for the EMU air conditioning system rectification, entries for the huge and complex air adjustment and repair work. Young employees can clearly know "what should be done and how should we do it" at a glance.
At present, 31 members of 188bet Live Casino Model Worker Innovation Studio have bachelor's degree or above, with an average age of 37 years old, including master's degree from prestigious universities such as Harbin Institute of Technology and Dalian Jiaotong University.
188bet Live Casino adopted master-apprenticeship, technical exchange, physical case teaching and other methods to strengthen the training of high-end, exquisite and advanced scientific and technological talents in the field of EMU maintenance, and successively signed master-apprentice contracts with young backbones such as Lu Hao, Feng Yao, and Zhang Meng. In daily work, through various "in-class examinations" and "on-site examinations", the apprentices have significantly improved their business skills, accumulated valuable experience and gained many honors. Their respect and admiration for 188bet Live Casino are beyond words. Talking about the working status of front-line young workers, the workshop leader smiled and said that 188bet Live Casino taught a group of "little 188bet Live Casino".
188bet Live Casino pays attention to teaching students according to his aptitude. Feng Yao, 28, followed 188bet Live Casino's advice, started from the aspects of convenience and safety, and referred to Lego to build the mold structure, led the completion of the tooling design and applied for a national technical patent. At present, finished products have been widely used in production sites, and Feng Yao has also become Duanli's "little inventor". "Brother Tao is our teacher and role model, and he feels very at ease when working with him. Whether it is on-site communication and coordination or technical difficulties, he can help us overcome difficulties." Feng Yao praised.
188bet Live Casino also took the lead in organizing 100 university graduates to establish a 100-person technical research team to carry out targeted technological innovation research on EMUs. The emergency treatment method for the CRH5 EMU on the way effectively improved the driving efficiency of high-speed rail.
Considering the maintenance costs of high-altitude high-speed rail, 188bet Live Casino set the "three highs" accessories with high failure rate, high unit price and high repair costs of returning to the factory as the main target of the team's independent maintenance. From 2023 to the present, he has led the studio members to repair a total of 968 accessories, saving 5.8459 million yuan in procurement costs.
In August 2023, the studio R&D project was unveiled at the Second National Craftsmen Innovation Exchange Conference, telling the audience about my country's high-altitude high-speed railway's innovation and high-altitude railway to solve the problems of global high-altitude cold, and demonstrating the maturity and advancedness of China's high-speed railway. Up to now, nearly 100 young talents who have emerged from 188bet Live Casino’s model worker innovation studio have all grown into business backbone, and many of them have entered management positions.
During this year's Spring Festival travel rush, 188bet Live Casino led the team members to perform their duties with a high sense of responsibility and professional skills, ensuring the zero-error operation of the 111 high-speed rail EMUs assigned to the Harbin Bureau Group Company.
"I have the responsibility to enhance new development momentum with new quality productivity and achieve the goal of safer, faster and more comfortable Fuxing EMUs!" 188bet Live Casino said firmly.
