Intelligent EMU maintenance robot overhauling high-speed rail trains The pictures in this article are provided by Shanghai Railway Bureau
In the Hongqiao EMU Application Center of the Shanghai EMU Section, a group of able-bodied "minions" took up their posts to overhaul the high-speed rail to help drive safety during the Spring Festival.
On January 27, the surging news (www.thepaper.cn) reporter learned from the Shanghai Railway Bureau that this is an intelligent EMU maintenance robot system developed by the group company, which was first put into use in 2019, with the addition of the "minion", the EMU maintenance time can be compressed by 20 minutes, and the intensity of the night work of employees is significantly reduced.
At night, when the EMU slowly drives into the maintenance depot, the technician presses the "Start Work" button, and the two "minions" will drive out from both ends of the stock road, waving their robotic arms and busy.
The intelligent EMU maintenance robot is overhauling the high-speed train
Yang Guang is the centralized control operator of the robot operation group overhauled by the Hongqiao EMU Application Institute, and the only "master" of the 8 robot terminals in the institute. "If you want the minions not to be lazy, you have to make fine adjustments at any time." In one night shift, the robot had to overhaul 20 groups of cars, twice as many as manual maintenance. ”
During the Spring Festival, with the increase of the volume of maintenance, it is necessary to grasp the dynamics of all the stock channels in the library at any time, and to prevent the robot from false alarms, and the energy must be highly concentrated.
The Hongqiao EMU is the first EMU in the whole road to use maintenance robots. At present, 8 robot equipment are controlled by 1 centralized control operator at the same time, and each group of EMUs overhauled by robots is equipped with only 1 maintenance personnel, which complements the robot.
"Squeak, squeak, squeak", "beep, beep, beep", accompanied by various prompt sounds emitted by the robot, the robotic arm is raised high, and from time to time it shoots blue light at the bottom bogie of the car. After more than 40 minutes, the robot slowly drove back to its original position. Groundwork mechanic Wang Xiaozheng took out the tablet, the robot's operating status, power, position and all the faults detected jumped on the screen, and two roof faults caught his attention.
Bring the work tools, climb the work ladder, and review the items one by one. As the backbone of the business, Wang Xiaozheng has been "partnering" with robots for more than two years, and the cooperation is becoming more and more tacit. During the Spring Festival, the daily running time and mileage of the EMU increased, the use of wear parts was more frequent, and common failures would increase, "Although the accuracy of robot maintenance is high, we still have to be fine and fine, almost not at all." ”
Zhang Yongjing, deputy director of the Hongqiao EMU Application Institute, introduced that two robots operate a train of 16 EMUs at the same time, which can complete the machine inspection in only 100 minutes, and the maintenance time is compressed by about 20 minutes, and the maintenance range can cover all models.
Since the Spring Festival, 30% to 40% of the first-level maintenance operations of more than 60 sets of trains per day at the Hongqiao EMU Have been completed by robots.
