"Bone Massage" and "Restorative Beauty"
"Assemble, get in the car and go!"
At 00:40 a.m., with the instruction of the person in charge of the construction of the "grinding car entering", the "rail beautician" of Guiyang Metro drove an orange grinding "god car" to the designated grinding site in the upward section from Laowantang to Yueshanhu Park.
At the operation point, the rail "beautician" lies on the rail surface and carefully checks the problems of the rail, "This place is a little sunken, just like the herniated lumbar disc caused by the curvature of the human spine, and it is necessary to 'straighten the bones' and then 'massage'." ”
After inspecting and repairing the rails of the day's operation section, the rail "beauticians" turned on the "repair and beauty" mode. "Turn on the operation mode, check the grinding parameters, turn on the grinding motor...... "grinding" god car" slowly moves along the rail line, and crystal sparks flash on both sides of the body.
In the process of "SPA" treatment, the "beautician" is engrossed in the car to monitor the operation of the grinding car, and adjust the corresponding operation mode in time according to the on-site rail grinding status and progress.
"This place was originally concave, which caused the impact force of the train to pass too much, and the wheels crushed the track surface into small 'wrinkles', and if not treated in time, the track surface would fall off." The "beautician" pointed to the track surface and explained to the new colleagues the reasons for the formation of fine lines and the importance of rail surface polishing.
Digital grinding is an important technology to polish the rail according to its wear and tear, eliminate the fish scale fine lines, poor light bands, fat edges and other diseases on the rail, ensure the smoothness and safety of the rail, ensure the safety of the subway train, and improve the comfort of passengers in the subway.
As of May 2024, Guiyang Metro Line 1 has completed the polishing of the 15,007-meter rail profile design, effectively improving the smoothness of the subway line and providing a more stable and comfortable riding environment for passengers.
After 150 minutes of professional treatment, the track surface that was originally full of "wrinkles" and "blemishes" is clean, bright and smooth. After the "treatment", the "beauticians" also have to accurately evaluate the "beauty" effect, and scientifically evaluate the GQI (rail profile) value based on the measurement data and the disease repair situation to ensure that the high standard of quality requirements is met.
"Rail beautician" with exquisite professional skills
And the craftsman spirit of excellence
Day in and day out, the rail lines of the subway are guarded
Those rails that have been polished to a bright and dazzling eye
It is a "glorious seal" left in the change of years
It is also a "full score answer sheet" handed over by the "rail beauticians"
