Intelligent Construction Improves Quality And Empowers The High-quality Construction of Xiyu High-speed Railway

Steel plate automatic cutting, automatic positioning feeding, section steel butt welding, intelligent cold bending molding, measuring equipment can be detected according to the position of the section steel, the operation of the robot with the plasma cutting machine, according to the length of the detected cut off or cut holes in the operation ......

This is a scene seen by the reporter today in the Kangyu section of the West-Chongqing high-speed rail station before the second standard No. 3 intelligent steel structure processing plant, which is mainly responsible for the processing of a variety of components, such as reinforcing steel mesh, small conduit, and other components processing tasks, innovatively integrating the processing of steel components with the Internet of Things + technology to fill the gaps in the tunnel construction industry.

The person in charge of the project department of China Railway Bureau told the reporter that since entering the field, it has earnestly implemented the project construction concept goal of "high-quality construction of 'high-quality, intelligent, green and humanistic' railroad project, and high-efficiency to build a new model of high-speed railroad in the west" of the Beijing-Kunming High-speed Railway Xikun Company. Adhering to the innovation drive, strengthening informationization and intelligent construction, the company has carefully built the No.3 intelligent steel structure processing plant with "Internet of Things+" as the intelligent core and lean management as the important support, which empowers the high-quality construction of Xiyu high-speed railway through intelligent construction.

The reporter saw at the scene that the section steel arch production line is assembled by automatic loading frame, servo control mechanical cold bending machine, 7 robots, 4 sets of shifting machine and palletizing robot. In the process, the servo control mechanical cold bending machine, which has the characteristics of fast rolling speed, high precision and one-time molding, can also be customized according to different requirements to adapt to the cold bending of double-arc steel sections. It can also recognize and accurately position for different types of section steel connecting plates and different positions of reinforcement plates. In order to facilitate continuous welding by robots, the welding procedure is parametrically programmed, and the mobile tipping device is combined with the welding robot to weld according to the programmed welding procedure, which not only improves the accuracy of welding, but also greatly reduces the complexity of the operation.

It is reported that No. 3 intelligent steel structure processing plant is also equipped with intelligent control management system. Integrated MES, SCADA and other systems to develop a digital management platform to create a multi-level intelligent management of the "black box of science and technology." MES manufacturing execution system contains material management, technology management, production management, daily management and data Kanban multiple functional modules. It truly realizes the "four" management of standardization of business process, agility of production execution, visualization of management process, and comprehensive quality traceability. SCADA data acquisition and monitoring control system realizes production data acquisition and analysis by docking with equipment PLCs, sensors, and other hardware, and real-time monitoring of the operating status of the production equipment, thus realizing Intelligent equipment control, real-time fault warning, production line data visualization, comprehensive safety production, and realize the whole process management digital intelligence.

"No. 3 intelligent steel processing plant, changed the traditional human-oriented operation form of steel processing, replaced by intelligent production based on intelligent equipment and digital management, this transformation greatly improves the efficiency of steel processing, reduces the cost, and realizes the maximization of the benefits of management and operation." The person in charge of the project department of China Railway First Bureau said that the project will take the intelligent construction technology as the leader, take the intelligent processing of steel components as the gripping hand, continue to promote the digital transformation of the enterprise, and continuously improve the construction level of the project of Xiyu high-speed rail project.
