Promote the transformation and upgrading of digital intelligence,Run out of the acceleration of new quality productivity

Railway Construction Heavy Industry applies artificial intelligence technology to product research and development、Design、Manufacturing and other whole processes,Continue to push the shield machine、Intelligent development of underground engineering equipment represented by drilling and blasting products。

Fully implement the digitalization of R & D and design、Intelligent manufacturing、Robotization of products、Service digitalization、Intelligent management“Wuhua”Strategy,Develop an integrated collaborative R & D platform,Application of digital twin technology for complex underground engineer equipment,Promoting the Deep Integration of Intelligent Manufacturing and Artificial Intelligence,Aiming at New Quality Productivity and Running out of Acceleration。

Application of Digital Twin Technology for Complex Underground Engineering Equipment in Railway Construction Heavy Industry,Stand up to the tide of technological innovation,Transforming high-quality innovative achievements into new productive forces

Railway Construction Heavy Industry Focuses on High-end、Intelligent、Green development,Optimize and improve the production process,Research and development of green intelligent equipment,Build a smart park,Assist“The carbon reaches the peak、Carbon neutral”。At the same time,Vigorously develop post-market business、Shield machine remanufacturing business and other new formats,Creating Green Remanufacturing Mode of Roadheader,Improve the technical standards and industrial development system of green remanufacturing of large-scale equipment,Realizing Green Remanufacturing of Equipment、Reapply,Create greater value for customers。In 2023, the company was awarded the National Intelligent Manufacturing Demonstration Factory.、National Green Factory。

Break through“Stuck in the neck”Key technologies,Realization of Localization of Main Bearing of Roadheader

The main bearing is referred to in the industry as a roadheader“ Heart ”,It is the only part of the whole tunneling equipment that cannot be replaced during service.。Because of the material、Design、Manufacturing and testing are extremely difficult.,Foreign countries monopolize it for a long time.,Not only is the price up to tens of millions of yuan,,Technology、Production and services are often controlled by others.。

To break foreign monopolies,China Railway Construction Heavy Industry Co., Ltd. set up a research and development team,Carry out independent research on main bearings,Hundreds of materials and processes have been tried,Tens of thousands of sets of data were analyzed,Many difficulties have been overcome.,So that that main bear can bear the pressure of ten thousand tons、Scroll the target for more than 10,000 hours.。

China Railway Construction Heavy Industry Co., Ltd. independently developed the world's largest diameter、The monomer is the heaviest、Main bearing of integral shield machine with the highest bearing capacity(φ8.61 meters)

The Second Industrial Park of Changsha Railway Construction Heavy Industry has been built into the largest industrial park in China.、International leading shield machine main bearing production line,Has been successfully developed 3 meters to 7..6m full range of main bearings,The world's largest main bearing working condition simulation test bed has been built.,It solves the worldwide problem that large low-speed and heavy-duty main bearings are difficult to test and verify.。October 12, 2023,With 8.The main bearing of the 61-meter domestic super-large diameter shield machine rolled off the production line smoothly,Tiejian Heavy Industry has thoroughly conquered and independently mastered the design of the whole series of main bearings of shield machines.、Material to manufacturing、Key core technologies in the whole test process,So that the domestic shield machine has a full range of China“Heart”。

Next step,The company will continue to improve the innovation linkage mechanism.,Strengthen the integration of resources,Promote technology enabling high-end equipment“The amount of intelligence”“Green content”“Gold content”,High-quality development of high-end equipment industry in China,Make new and greater contributions to Chinese-style modernization。
