Trinity reloaded
With the development of mine intelligent products, Sany Heavy Equipment has formed a new system with intelligent tunneling equipment (intelligenceTBM) and remote centralized control platforms (underground centralized control rooms, ground operation platforms) as the main product ecology. Sany Heavy Equipment's intelligent products have won the favor of more and more customers because of their high stability, high reliability and strong adaptability.
At present, Sany Heavy Equipment intelligent TBM has been distributed in most regions of China, and the construction of "model mine" has been completed in the northeast region, and the first EBZ160i intelligent TBM in Northeast China has successfully passed the acceptance of high-quality projects in Dongrong No. 1 Mine of Shuangyashan Mining Group Company.The cutting efficiency of the intelligent TBM of the "model mine" has reached and exceeded the manual cutting efficiency, and the automation utilization rate has exceeded 50%.
In addition, in more than 100 mines in Shanxi, Shandong, Inner Mongolia, Shaanxi, Guizhou, Xinjiang, Henan, Anhui, Gansu, Ningxia and other places, Sany Heavy Equipment intelligent TBM can be seen.
In the future, with the blessing of intelligent TBMs and remote centralized control platforms, the level of "intelligence, less manpower, and unmanned" of the underground working face will be further improved, and the strategic goal of "mechanized substitution, automation reduction, and intelligent manpower" will also be further realized.
Why can Sany Heavy Equipment's intelligent TBM be widely recognized by customers?
Sany Heavy Equipment intelligent TBM has continuously carried out technological upgrading and innovation according to the actual needs of customers and on-site construction conditions, and made breakthroughsPrecise positioning technology, over-the-horizon control technology, automatic cutting technology, online monitoring technology of cutting trajectory, remote visualization technology, underground electronic fence and limit system, digital platform system and many other cutting-edge technologies, to provide assistance for the construction of smart mines.
Through the convergence and integration of various technologies, Sany Heavy Equipment intelligent TBM has excellent performance and outstanding advantages in the production and application process.
Underground environmental perception
Binocular vision technology + inertial navigation: based on visual pose calibration, accuracy ± 5cm. The roadway offset is automatically calculated, and manual pointing is canceled. (Attitude calibration is done manually every 2 hours)
Walking trajectory planning
Inertial guidance system + laser ranging + multi-sensor fusion technology: automatic deviation correction and automatic straightening of walking, and the error of the cumulative advance of 10m is only ±20cm.
Truncation trajectory planning
Trajectory online monitoring + independent path planning + telescopic compensation technology: a variety of roadways (arch, rectangular, trapezoidal) are automatically formed to avoid over-excavation and under-excavation, and section forming errors<10cm。
3D Health System
3D simulation + predictive maintenance technology of TBM: TBM attitude visualization, real-time monitoring of operation data and predictive maintenance of key components (oil pumps, motors), with a prediction accuracy of > 85%.
