Once，He is an ordinary internal combustion machine holder。Now，He is a "big machine doctor" who master 5 railway professional technologies such as automatic control "。
initial，He is a technical white that is helpless in the face of the big machine，Hundreds of maintenance personnel trained now have become the backbone of the maintenance of the aircraft。
44 -year -old China Railway Taiyuan Bureau Group Co., Ltd. Taiyuan Work Machinery Section Comprehensive Comprehensive Comprehensive Comprehensive Workshop Electric Working District Leader Liu Xingxing，More than 10 years has always been based on positions、Diligence，Delivery and maintenance of large -scale road maintenance machinery and maintenance，Dedication of youth to the railway business that is struggling for it。The "Case Manual of Large Road Conservation Mechanical Fault Cases" he wrote、The "Annual Repair Guidance for the Large -scale Road Machinery Machinery" participating in the preparation has been widely promoted and used。
Diligence practicing hard -in -space diagnosis
March in Nantong Pu Line，Clear sieve car、Maker and Returning Cars、With a car car、Dynamic stabilization vehicle ... a large road maintenance machinery of a connected marshalm is，It's like a steel long 188bet login188bet logindragon drive to the construction location，Fast launch of maintenance operations。"These operating cars are all sets、Electric、liquid、High -tech equipment that integrates a variety of professional technologies such as qi，is the ‘Hercules”。"" professional maintenance personnel to maintain large machine equipment，Liu Xingxing Introduction。
With railway technology and equipment innovation，Route equipment maintenance operation method has been fully shifted to "mechanical repair、Concentrated repair、Professional repair "，High performance、High -efficiency large -scale mechanized equipment has become the main force of labor repair。
2012，To meet the needs of the large -scale maintenance organization，Liu Xingxing was transferred from Houma Bei Machine Said to the establishment of Taiyuan Working Machinery Section shortly after the establishment。This is the only labor mechanical section of the Taiyuan Bureau Group Company，Brottering in the tube of the tube、Clear sieve、polishing、Replace the rails and other important construction tasks。
"You can only find a manufacturer in the initial equipment.，But long maintenance cycle、High cost。Autonomous mastering the maintenance technology is imperative。"Facing 10 categories、More than 100 major aircraft，Liu Xingxing thought，"I used to repair the locomotive，Now repairing the big machine，There must be no problem。”
But really dry，Liu Xingxing really realized that the interval is like a mountain，Maintenance is far as simple as imagined。In the past, only internal combustion locomotives，There are many types of large types of large machines;，Repairing machine requires professional technology "one specialization"。The tremendous changes in the technical knowledge structure inspired the energy of Liu Xingxing's inner heart。"I am still young，You have to learn，Just do it! "Liu Xingxing secretly determined。
A car，Thousands of bolts，tens of thousands of terminal interfaces，The heaviest parts weigh hundreds of kilograms，Liu Xingxing repeatedly disassembled hundreds of times，Gradually figured out the basic structure and maintenance process of the vehicle。188bet login188betNot long after，He encountered a real problem -increased hydraulic oil temperature caused the operating vehicle to automatically disclose pressure。In order to find out the crux of the problem，Liu Xingxing did not get off the car for two days and two nights，Until I accidentally heard a horn sound，He only remembered that his car had a problem of rising water temperature due to the deficiency of the line。Follow this idea，He finally found the reason why the temperature of the hydraulic oil was higher。
Deeply experience Liu Xingxing, which is completely different in the maintenance mode，Start learning electrification、Automatic control and other professional knowledge。"He couldn't see anyone in the car in 60 days outside，After returning home，I fell asleep as soon as I leaned on the sofa。"Liu Xingxing's wife said distressed。His home is full of professional books and materials related to large aircraft，There is also a notebook with dense data full of data and maintenance experience。
After 2 years of research and exploration and on -site refinement，Liu Xingxing's technical advancement。In order to better play the technical advantage，He opened the "Thousands of Miles" service hotline，24 hours for transportation first -line service，For the vehicle failure "space -free diagnosis pulse"。
Whether it is a lane system or not working or a tinkering device，He can always give solutions quickly on the phone。Benefit as a "diagnosis of the air"，Chen Jun, director of the Hugong Total Workshop, said: "Encountered difficult problems，The first thing I think of is to call Liu Xingxing。He can not only quickly and precisely point out the problem、Give solutions，After that, I will go to the scene to check on the spot，Make sure that the problem of problems is accurate and correct。”
Precise debugging overcome difficulties
2019，Zhang Da high -speed rail enters the key line fine tone stage。Liu Xingxing, who has the heavy delegation of equipment debugging, faces unprecedented challenges: within 3 months，Dispel the orbit TQI value of more than 100 kilometers from 8 to below 2.5，It means that the error of each large machine action must be controlled within 0.3 mm。
188bet mobile login188betDespite the difficulties，Liu Xingxing and the team are still fighting spirit，But the TQI value fell into stagnation after falling to 2.7。During that time，They analyze tens of thousands of groups of data、Try hundreds of solutions，After countless failures and attempts，Finally successfully cracked the problem of the accuracy control of the operating accuracy of the minting vehicle，Created a new record of the TQI value of Taiyuan Bureau Group Company。This technological innovation is not only applied to Zhang Da's high -speed rail，and extensively promoted in the construction of the subsequent Zheng Tai high -speed rail and other lines，Make the line quality reaches the leading level of the entire road。
Test one round and one round.
In recent years，The average daily transport volume of the Daqin Line is about 1.1 million tons。To ensure construction、Transportation is not wrong，Taiyuan Bureau Group Company accurately calculate each centralized task to minutes。Liu Xingxing is deeply responsible: "The most worried during the centralized repair period is the failure of the large aircraft，Once the maintenance task in the ‘Sky Doom’ is postponed，It will affect the completion of the freight volume of the day。”
During the National Day in 2022，Liu Xingxing encountered the most difficult problem on the Daqin Line -centralized rectification of bridge eccentricity and lane problems。
Daqin Line uses heavy track pillows，Most of the bridges are at the curve，The amount of conscientiousness exceeds the previous single number of dials，And it is only one hour left for large machine operations。"Large Dial Quantity、Multiple jobs、Steel Rail Blind、Personnel operation、There are many influencing factors such as the density of Shiji。"Liu Xingxing said，"The small changes in any link will bring serious consequences。”
To overcome this difficulty，Taiyuan Bureau Group Company held a special meeting，Taiyuan Working Machinery Section Establish Research Research Group。Liu Xingxing as the backbone，Quickly convene a group member to conduct comprehensive assessment and testing on the performance of the motion mortar car according to the line 188bet mobile login188bet mobile logindata，Research determines the construction plan: 1.5 kilometers、More than 1,200 tinkel movements。To ensure that every accuracy is up to standard，He checks the wear of the vehicle parts one by one，Think of how to eliminate the tiny electrical、Mechanical error。The transition section of the curve and line line，He organizes a group member on the car and cooperate with the car，Timely adjustment of mounting data，and guide the staff of the vehicle group to control the rebound amount，Make sure the accuracy of the way of dialing，Finally successfully complete the centralized rectification task。
According to different lines、Different operating players，Adjust the operating status of the vehicle on demand，Basically, one strategy of first -line、One car and one strategy，This is Liu Xingxing actively penetrating the front line、"Safety Book of Safety" summarized by emergency repair。From 2013 to the present，His average of more than 200 days a year assisted in the construction site，A total of more than 4,000 faults，Cumulative schedule exceeds 100,000 kilometers，Footsteps all over the pipeline all railway trunk lines，Where is it difficult，Wherever there is his figure。
Teaching technique blooming
Dugu does not become forest，Zhongzhi can become a city。As a leader with rich experience and superb skills in the field of large -scale maintenance，What he wants to do most，I taught my knowledge and experience to more colleagues，Lead the entire team to advance together，Contributions to the safety and unblocked railway to contribute more forces。
As the person in charge of the model worker innovation studio，Liu Xingxing actively exerts the role of passing the gang，Lead the employees around them for failure traceability，Principles of the faulty accessories、Structure、Action process、Maintenance and maintenance method is made into an electronic fault library;、Check、Repair "closed -loop process and electrical group standardized operation process，Meeting the needs of 16 models and the demand of more than a hundred major aircraft amendments。The team has completed a total of more than 200 188bet mobile188bet loginitems for employees' innovation results，Among them, 50 results have been improved by the bureau's group company level rationalization suggestion improvement award，Wind Gear Box Alarm Device、Concentrated lubrication automatic control system and other more than 30 achievements are promoted and applied in the scope of the global group company，5 people have obtained bureaus group company -level technical experts。
33 -year -old Yang Xuefeng follow Liu Xingxing to learn the debugging technology of the big machine。At first he felt a little struggling to this: "Not only does it need to master solid professional knowledge and practical skills，You need to change your thinking，From the perspective of vehicle design, try to figure out。”
In the process of completing the mission of Zheng Tai's high -speed rail，Yang Xuefeng cannot clearly feel the direct relationship between parameters and pressure in the control link of the hydraulic system，Liu Xingxing patiently explained every detail for him，Adjust the parameters while adjusting，Professor Yang Xuefeng carefully observed the activity status of the hydraulic oil cylinder，Feeling the impact of data fine -tuning on the quality of operation。Under the careful guidance of Liu Xingxing，Yang Xuefeng gradually grows from novice to the leader in the debug field。
"Repair every year now、The total mileage of the maintenance line exceeds 10,000 kilometers。The large machine is constantly upgraded and replaced，Our maintenance ability must also keep pace with the times。"for this，Liu Xingxing leads the establishment of a large aircraft on -site classroom，Special training classes for large -scale maintenance personnel，Principles of the large machine structure、Fault repair、Maintenance rules and other theoretical knowledge，Use construction maintenance gap，Investigate the fault of the handle of the handle、Emergency disposal、Excited debugging and other professional practice，Transport nearly 300 inspection personnel at the construction site，significantly improved the technical level of the overall group company's large aircraft。
Lifting Liu Xingxing，Wang Longman, Secretary 188bet login188betof the Party Branch of this section of the Taoist fork, is grateful: "His exquisite skills and rigorous work attitude，Make many difficult equipment problems be successfully solved。You can say that，Driving is the master taught by the master，He taught me to drive the car well! "
Starlight does not ask the passers -by，Time lives up to the people。Liu Xingxing can't remember how many nights are spent on the line，But he knows that as long as he keeps moving forward，can overcome difficulties，Realize your dream。

Interview Notes: Can suffer hard and not accept the dare to take responsibility
In the process of interviewing Liu Xingxing，I can always hear the surrounding maintenance personnel、The operator praises him as a "big machine doctor"，Big machine faults that many people cannot handle，In particular, it is difficult to distinguish the cause of the cause，He can always accurately diagnose、Hand -to -disease removal。Liu Xingxing praised by everyone said: "Safe in large aircraft safety，We blame without loan。”
Machine maintenance requires all year round operations，It is a very hard -working and challenging job。In more than 10 years of more than 10 years，Liu Xingxing has grown from a locomotive guard to a "big machine doctor"。From on -site maintenance to "space -free diagnosis"，On him，What we see is the stream of hardships、Don’t accept losses、Dare to take responsibility。He showed the spiritual style of railway people in the new era with actual actions。Railway high -quality development calls more skill talents like Liu Xingxing。
