Research on the life optimization method of middle trough of scraper conveyor based on multi-orientation
The scraper conveyor is one of the main mechanical equipment in fully mechanized mining face,and its comprehensive performance directly affects the mining efficiency of coal mines.The middle trough is an important component of the scraper conveyor,which is prone to wear,fracture,and other faults under heavy load and long-distance working conditions,causing safety risk.On the basis,the main factors affecting the life of the middle trough were analyzed,a life optimization method of middle trough based on multi-orientation was proposed,which used high-quality alloy steel casting to enhance the strength of middle trough,selected robot welding to replace manual welding to improve weld reliability,and adopted a new wear-resistant material to improve the overall wear resistance of the middle trough.The experimental results showed that compared with traditional middle trough,the middle trough produced by this method had significant improvements in performance indicators such as hardness,tensile strength,and wear resistance.
