Por que os mineiros de âncora usam placas de aço compostas resistentes ao desgaste?

Introduction to Anchor Miners

Anchor miners are specialized machines that integrate cutting, carregando, transportando, andando, ancoragem, e remoção de poeira. Permitem operações simultâneas de escavação e ancoragem. Essas máquinas usam controle de velocidade de frequência variável para movimento, oferecendo forte tração. O suporte temporário pode ser estendido até a cabeça, minimizando a distância do telhado sem suporte, allowing them to adapt to various roof conditions. During cutting operations, a groove cylinder is used for advancement, keeping the machine stationary and reducing vibration.Wear-Resistant Composite Steel Plates

These features significantly enhance excavation, support, and transportation efficiency. They optimize operations, enabling fast, efficient excavation while improving workers’ safety by reducing labor intensity and risks. The automation of coal tunnel excavation and support is also achieved.

Loading Mechanism of Anchor Miners

The loading mechanism of an anchor miner consists of two main parts: o carregando e transportation sections.

• Loading Section: This includes the shovel plate body, rake claw, loading motor, and reducer. The loading process occurs through the rotation of the rake claw, which moves cut coal, gangue, and other materials to the transportation section.
• Transportation Section: Comprised of the front, middle, and rear transportation troughs, the scraper chain, driven by the conveying motor and reducer, continuously transports materials. The friction between the coal and the scraper chain causes wear on the middle plate, bottom plate, and side of the trough. This wear leads to material loss due to the friction and large abrasive particles, which create deep scratches and surface damage.

Importance of Wear-Resistant Composite Steel Plates

The key challenge in anchor miner operations is minimizing wear on the machine’s loading mechanism. The use of wear-resistant composite steel plates for the shovel plate and the middle trough in the transportation structure addresses this issue. These plates improve the machine’s durability, reduce maintenance time, and lower costs. Enhancing the wear resistance of the loading mechanism is essential for extending the lifespan of anchor miners and ensuring efficient operations.
