Yan Yankai "does not decelerate" in the dowty retarder repair work area of Linyi Railway Station of Jinan Railway

Dowty retarder are one of the important transportation equipment for railway hump shunting operations. Once a problem occurs, it will cause trucks to overspeed and cause accidents such as collisions and cargo movement. Therefore, the maintenance work of the dowty retarder is very important. Yan Yankai is the team leader of the dowty retarder maintenance area of Linyi Station in Linyi Depot. He strictly implements standardized operations, puts risk control measures in place, and completes maintenance tasks with high quality as planned, ensuring the safety of hump shunting operations.

In order to cultivate the skills of dowty retarder maintenance, Yan Yankai worked hard to learn theories, delving into the whole set of business processes and key operating points. Taking advantage of the off-duty time, he went to Hanan, Luohe, Dezhou and other stations to apprentice skills, and combined the knowledge learned with the actual situation of the station, and formulated a set of more practical methods of "repair, management and use" of the dowty retarder. Under his leadership, the guys have a strong interest in learning, and daily faults can be repaired and dealt with in time.

In terms of equipment management, Yan Yankai established a complete set of maintenance files and created maintenance cards for all 2,520 dowty retarder in the field, so that the dynamics of the retarders can be accurately grasped, and the operation of the retarders with diseases that are out of service can be avoided. Because of the 18 coal unloading, the dowty retarder has poor lubrication all year round, which seriously affects the return journey and threatens the safety of shunting operations. According to the actual situation on site. He revised the document to provide for regular maintenance twice a year and revised it to four times a year, eliminating the hidden dangers of the equipment in time. Since November 2009, the station has held many self-management equipment analysis meetings, and he has provided suggestions and suggestions every time, and has provided detailed technical information to the station many times to truthfully report the problems and hidden dangers of the retarder to the superior. In the past three years, the superior has invested more than 4 million yuan to update the station computer control system, track circuit, power supply equipment, and speed reducer, which provides a guarantee for the safety of hump shunting operations.
