On the preparation field of the Guangzhou engine section, a dazzling spark burst out. Hang up the pulling machine, wave the signal flag, hand up and down, with the insulating rod controlled by Xie Yousheng's hand, between the current on and off, a locomotive is slowly and accurately walking and stopping and hanging on the preparation yard, exactly the same as the predetermined parking position...
The train runs fast, all thanks to the headband. Even if the steel dragon weighing thousands of tons, as long as it is hung up, it can gallop at high speed on the land of Shenzhou. But once in the powerless zone, this powerful "dragon head" will seem to be sleeping, at this time, the movement of the locomotive is all controlled by the puller on the ground. Xie Yousheng, 57, is a car puller in the maintenance workshop of the Guangzhou engine depot, and this year is his 28th Spring Festival.
The "Royal Dragon Rod" in Xie Yousheng's hand is about 1 meter long, insulated throughout, and the bottom is a piece of brass, which is connected to the inside of the locomotive through a cable. Every 5 meters forward, the conductive copper at the bottom of the rod touches the charged black ground row on the ground, and the current flows into the locomotive through the wire, and as the bottom of the rod touches it, a brilliant spark instantly blooms, and the locomotive begins to slide slowly.
"Don't look at this spark seems to be very simple, the length of contact time, the angle and position of each point of contact will directly affect the effect of pulling the car." Xie Yousheng said that different models, different trailer distances, and even the driving habits of the drivers on the car are particular, which has strict requirements for the time of the touchdown. The 1A 380v current released by the touch control row ensures that the locomotive slides at a speed of no more than 5km/h, which seems to be a simple action, but the actual operation is not simple at all. If the touch time is too short, the traction locomotive will have insufficient power, and it will not be hooked up when the locomotive is attached, and even affect the efficiency of trailer operation; The touch time is too long, and the locomotive power is too large, which will cause the locomotive to impulse, collide with the locomotive in front and even damage the coupling buffer. This requires Xie Yousheng to not only be particularly familiar with the performance of the locomotive during ordinary operations, but also to wake up the spirit of twelve points during operation and always grasp the movement state of the locomotive.
Xie Yousheng said that this work is particularly exercise, more than 300 pounds of car puller back and forth, in the wind and rain on the preparation field, an average of more than 20,000 steps per shift, he also dominates the WeChat sports step rankings all year round. The cool-looking "Royal Dragon Fire Man" has long practiced a rough "copper skin and iron bone" under the wind and sun. However, this is already familiar to Xie Yousheng, who is facing the 28th Spring Festival, "Although a class often has numb legs and sore feet when walking down, every time I see the locomotive can leave the warehouse on time and put into the transportation of the Spring Festival, it is all worth it." ”
