Zhang Zhiqiang, the foreman of the Yuanping Inspection Andress Second Engineering District of the Yuanping Engineering Section. He has been engaged in rail flaw detection for 17 years, loves his post and dedicates himself to his work, studies the business, not only has he created 17 years of flaw detection without leakage inspection, repeatedly found seriously injured rails, ensured the safety of the train, but also won many honors, is recognized by cadres and workers as a professional "leading goose", technical "big taker" and "safety hero".
The love of "love"
In July 2000, he graduated from taiyuan railway adult secondary school and was assigned to the Yuanping Engineering Section as a road maintenance worker. In April 2004, he was transferred to another job as a flaw detector.
Rail flaw detectors are more technical and hard work in the railway system. Whether it is a hot summer, or a cold and windy winter, whether it is the flood season of wind and rain, or the season of ice and snow, throughout the year, they push the injury detection trolley, walk more than ten kilometers a day, and constantly carry out "physical examinations" for every inch of steel rail.
In the face of such a brand new post, he did not choose to play the drum and retire, but chose to face the difficulties, and deeply fell in love with this post, working for 17 years.
Flaw detectors are people who specialize in using rail flaw detectors to do B-ultrasound for rails, check whether there is internal injury inside the rails, and then "whistle" for safety. Therefore, it is difficult to take on this responsibility without strong business skills.
In the past 17 years, he has learned from the most basic business, and has become his close friend in business books such as "Rail Flaw Detector" and "Flaw Detector Should Know". In particular, thousands of question banks should be known, and he can memorize them in his heart.
Theory is important, but practice is fundamental. He knows that as a doctor, having theoretical knowledge and not seeing a disease equals zero, and the same is true for a flaw detector. As soon as he had time, he studied the structure and principle of the rail flaw detector, the use and maintenance of the rail probe; when he arrived at the scene, he humbly consulted the teacher, did not tire of asking this and that, and fought for the opportunity to carry out the machine every day, and practiced practical skills.
Kung Fu pays off. After several years of diligent study and hard work, he quickly achieved a gorgeous turnaround, quickly grew into a qualified flaw detector, and successfully obtained the highest level - the third level of flaw detector qualification, flaw detector senior technician.
Technology is in hand, the responsibility is on the shoulders. Steady and capable, quick thinking, exquisite technology, he is seen by the workshop cadres in the eyes of the use of things. In 2009 he was appointed squad leader for the 42-person squad, and this year he served as foreman.
"The burden is heavy and the responsibility is great. In the post of foreman, I want to lead the staff to practice their skills, train the golden eye of fire, accurately 'physically' check every inch of the rail, put an end to missed inspections and misjudgments, timely discover hidden dangers, be a good safety pioneer, and play a good role in the first line of defense of safety! He said firmly.
"Look" carefully
The depth of the flaw detector is to determine whether the rail has internal injuries in the ticking sound of the flaw detector and the waveform of the electronic screen.
In the operation, he conscientiously implemented the "one slow two look three to stand at a large waist and even speed probe" flaw detection operation order, strictly prohibit overspeeding, carefully check the electronic screen display waveform changes, stay in the turnout area, rail joint lots, etc. for a while, probe a few more back and forth and manual inspection, probe evenly, and implement the operation standards at a glance.
As a team leader, he is responsible for on-site safety and ensures the quality of operation every day. Therefore, in addition to the standard operation of the inspection staff, he must personally carry out the inspection in general, especially the operation in key areas, to strictly prevent the occurrence of missed inspections.
One day in July 2011, when he led the operation team to inspect the 352.100 kilometers between the Gyeongwon Line and the Zaolin Forest, he heard that the operator had an abnormal alarm when he was carrying out the machine, and after repeated inspection on the spot, it was confirmed that the rail was seriously injured, and he quickly notified the workshop to deal with it in time. There are many more situations like this.
In his work, he is also good at studying various "difficult and complicated diseases" in flaw detection and overcoming one difficulty after another in safe production. Small radius curve lot is a difficult point in the detection operation, due to the wear and tear of the rail caused by the poor coupling of the probe and the rail surface, which seriously affects the detection effect, it is easy to cause missed inspection or misjudgment, and lays a major safety hazard for transportation safety. In order to solve this problem, he began to tackle technical problems.
After repeated on-site research and experiments, the "probe and rail head coupling system" was invented, that is, the use of oil as a couplant, through the method of grasping the probe by hand to check, effectively solved the drawbacks of affecting the flaw detection due to the poor coupling of the probe and the rail surface, and plugged the loopholes in the flaw detection operation.
In view of the problem that the early small nuclear injury in the center of the rail head is not easy to find, he actively carried out technical research, and adopted the detection method of reducing the declination angle of the probe and the position of the probe appropriately deviating from the center of the rail head, which effectively improved the detection probability of near-surface nuclear injury in the center of the rail head.
In his 17-year career as a wound tester, he has traveled more than 800 kilometers of lines, all turnouts and station lines, and he knows every inch of rail conditions in the tube, which key sections need to be encrypted, and which diseases need to be "scrutinized and carefully examined". Every suspicious place found must be carefully analyzed to achieve "three do not let go": the cause analysis is not clear, the qualitative is not accurate, and the disposal task is not released.
He said: "As a flaw detection foreman, you must have excellent business skills, and you must have the ability to find and solve safety hazards. Only by checking one place and protecting one place can we ensure the quality of flaw detection and ensure safety! ”。
"Dry" shines
"If you want to do it, you have to be first-class, and ordinary posts are also outstanding!" This is Zhang Zhiqiang's work pursuit and goal.
Not tall, strong, dark, rough, wind-like steps... Everything is a testimony to his long-term field work, weathering the baptism of wind and rain into steel, and it is also a true portrayal of his sweat for safe production.
At the scene, people can always see his wind and fire figure. One day in August 2013, the temperature was as high as more than 30 degrees, the temperature of the rail reached more than 50 degrees, and every touch of the rail was hot. Only to see him check the staff from time to time to pay attention not to speed, even speed and careful exploration, and from time to time crouch down and stand up, climb on the rail to observe the status of the rail, and listen carefully to the sound emitted by the flaw detector. When inspecting the aluminum weld at 357.200 kilometers of the Gyeongwon line, the abnormal situation was found and the operator was reminded to pay attention in time. After careful inspection, it was found that the rail had a large core injury, and measures were taken in time.
One person's technology is not good, all employees are really good, and the safety factor will be higher. All newly hired employees, he is extremely strict and personally serves as a teacher, teaching business and practicing skills by hand. This year, Duan established a "flaw detector training base" in the workshop, and as soon as he had time, he led the staff to practice, so that the new people's business and technical level was quickly improved.
In order to improve the flaw detection management, he used his spare time to communicate and discuss with peers through the network, and established a variety of basic management such as B obvious injury database, playback suspected damage registration book, playback base material key location registration book, playback reinforcement weld registration book, etc., which improved the self-management ability of the team and effectively realized the monitoring of on-site rails.
He is not only satisfied with the mastery of old technology, but also attaches great importance to the development and research of new technologies. In 2018, the flaw detection workshop should use a double-track trolley, and he will find information, ask for the help of his peers, and understand and master the double-track instrument in advance. Due to the design reasons, the circuit wiring is unreasonable, and the line is often hung up when passing through the turnout, which not only affects the progress and quality of the operation, but also causes greater economic losses. He conducted research and testing on this problem in time, and installed an anti-hanging wire hook for the dual-track instrument to eliminate such problems. The "Five Smalls" and technological innovations led and participated in by him have also won many awards.
Everything must strive for the first, which is the professional pursuit that Zhang Zhiqiang has cultivated for many years. He actively participated in various skill competitions held by Duan and group companies, maximized the opportunity for himself to improve, and won gold and silver many times. In 2008, he participated in the technical competition organized by Duan and won the title of "Top Ten Youth Job Experts". In 2014, he participated in the Road Bureau Flaw Detection Skills Competition and won the first place. In 2020, he participated in the two-track flaw detector operation of the group company's flaw detector vocational skills competition and won the first place in the actual score, the second place in the comprehensive score, and the first place in the group score.
One point of hard work is one point of harvest. In the past few years, he has successively obtained the qualification of senior technician, the chief technician of the group company, obtained the UT level 3 certificate of nondestructive testing technology, etc., and won the titles of "Taiyuan Railway Bureau Technical Expert", "Professional Skills Top Talent", "Taiyuan Railway Bureau Excellent Communist Party Member", "Taiyuan Railway Bureau Advanced Individual" and so on.
Drip-drip-answer-answer... The sound of the rail flaw detector is constantly ringing, Zhang Zhiqiang's footsteps of measuring the rail are constantly walking, and he is stronger in his will to ensure the safety of the railway!
