Coal mining expert, wisdom and courage - Sany Heavy S series intelligent shearer

Since the advent of the first shearer in 2006, after more than 10 years of innovative research, Sany has formed a series of products suitable for thin, medium and thick coal seams, with an installed power covering 385kW-2590kW and a mining height range of 0.8m-8m, with a total of more than 30 models in 11 series of mature products.

Sany Heavy Loading Shearer has a number of leading technologies such as super wear-resistant materials, heavy-duty rock breaking drums, inverter anti-vibration technology, inverter master-slave switching, etc., and has obvious advantages in reliability, adaptability, maintenance and intelligence. thereintoThin seam shearerIt is in a leading position in China, with a total sales of more than 200 units, and has set a record of high production in thin coal seam mining in many mining areas.

February 2021Sany Heavy Equipment launched a new generation of S series intelligent shearerThis series of intelligent shearers has a number of core technologies such as learning memory cutting, automatic straightening of the working face, predictive maintenance of the cutting section, and C-end intelligent cloud platform.

1.Learned memory truncation

Multi-sensor fusion, equipped with dual DSP+dual ARM high-performance controllers, to establish a learning memory truncation model. In the automatic cutting mode, the shearer can realize the functions of automatic height adjustment, undercover, reversing, acceleration and deceleration through self-learning, and the automatic operation rate of the equipment reaches more than 80%.

2.The working face is automatically straightened

It integrates mechanical, electrical, hydraulic and inertial navigation systems to realize the high-precision positioning of the shearer's operation and cutting trajectory, and completes the independent height adjustment of the shearer and the automatic straightening of the scraper, with a linear deviation rate of ≤1‰ and an accuracy deviation of ≤0.05°, reaching the industry-leading level.

3.Predictive maintenance of the cutting section

Based on multi-sensor fusion technology and intelligent diagnosis technology, it realizes the functions of condition monitoring, fault diagnosis, and life prediction of bearings and gears in the rocker arm, with a prediction accuracy of > 90%, which can check the hidden dangers of equipment failures in advance, make maintenance more accurate and efficient, and greatly improve mining efficiency.

4.C-end intelligent cloud platform

Real-time collection of equipment information, the use of high-speed transmission technology to send massive data back to the Sany cloud platform. Realize the in-depth mining of shearer data, push health status, fault warning and maintenance information, and timely maintain, maintain and troubleshoot the equipment according to the information pushed by the platform, which can effectively reduce abnormal shutdown and ensure the stable operation of the equipment.
