Design of line friction-driven pressure-enhancing equipment for mine long-distance belt conveyor
Mine long-distance belt conveyor has characteristics of long transportation distance and large quantity of trans-port,easily resulting in the over friction of belt with full load and serious energy consumption without load.In order to effec-tively solve these issues,based on the main operational conditions of line friction-driven belt conveyor,and considering the main layout of the belt conveyor,the main operational characteristics of the belt conveyor in the concave ad convex arc sec-tions is discussed,the belt-side pressure-enhancing mode is studied,a friction-driven pressure-enhancing equipment is de-signed,and its pressure-enhancing effect is simulated.The results show that after application of the pressure-enhancing e-quipment,the friction formed between bearing belt and transmission belt can be automatically adjusted according to the oper-ational load,thus solving the existing inadequate power of long-distance belt conveyor,extending the life of belt conveyor and promoting the energy-saving and efficiency-boosting of the transportation system.
