Guangming ** reporter Zhang Shiying Guangming ** correspondent Zhang Long Tao Le.
At 4 o'clock on February 4, the outdoor temperature in Harbin, Heilongjiang was as low as -28, and 1196 kilometers up the Beijing-Harbin Railway, Chen Chen, a catenary worker, stood in the snow, holding a grounding rod 6 meters long and weighing more than 20 pounds, and was preparing to connect the ground wire.
The Beijing-Harbin Railway is an electrified railway, which is one of the important passages connecting Beijing and Harbin. This winter, ice and snow tourism in Harbin exploded, and the number of tourists surged. Since the beginning of the Spring Festival, nearly 100 passenger trains arranged by the railway department on the Beijing-Harbin Railway every day have been almost full.
Affected by the vibration caused by the high-speed running of the train, some of the fasteners of the catenary may be loosened, especially in the extremely cold weather in winter and the increase in the frequency of train operation during the peak hours of passenger flow, which is also more affected. In order to ensure the safety of railway transportation, catenary workers should use the "skylight" maintenance time to conduct a comprehensive inspection of the status of catenary equipment, focusing on inspecting and dealing with the possible loosening, detachment, stuck, broken and other phenomena of various components of the catenary.
Lifting, pushing, and hanging, after a series of flexible operations, the grounding rod was easily hung by Chen Chen on the oblique wrist arm. The first process of online inspection took her only 2 minutes. "The second group of ground wire hooking is completed. With the walkie-talkie call of Xu Tongwei, a guard worker, Su Herui, a catenary worker dozens of meters away, checked the safety belt on his waist and began to climb to the top of the pillar.
Keep your hands firm, your feet steady, pay attention to safety, and strictly prevent slipping. Foreman Lin Weiqiao reminded loudly.
Looking from under the pillar, Su Herui's body was almost suspended in the air. She hung up her seat belt, held the high-voltage line in one hand and a torque wrench in the other, knocked on the catenary screws and connections, and took a flashlight from time to time to check carefully.
On the railway line, the knocking sound of the tool wrench" ** and the sound of commands from the walkie-talkie from time to time are intertwined. Less than 30 minutes before the end of the "skylight" operation, Su Herui began to climb to the top of the third pillar. At this time, snowflakes drifted in the sky, and the wind wrapped in snow and blew people unable to open their eyes.
So high, scared not? "There's nothing to be afraid of, I'm used to it. In the face of the reporter's question, Su Herui, who had returned to the ground safely after completing the homework, replied with a red face from the cold.
There are 14 post-95 girls like Chen Chen and Su Herui in the Harbin Power Supply Section of China Railway Harbin Bureau Group, and they are affectionately called "female flying heroes" by male colleagues.
At 6:30, the sky was just dawning, and the girls who had finished their work got on the engineering truck back to the work area. "Today is off, don't sleep too much, let's go to the Ice and Snow World to join in the fun. Chen Chen's proposal was unanimously approved by the little sisters. "I'm going to take pictures! "I'm going to ride the big slide!" The girls were gossiping, and the yellow engineering vehicles were like beating flames, warming their hearts ...... excited
