摘要
针对矿用长距离皮带机存在运输距离长,运量大,在满载时易造成皮带过度磨损,在空载以及少载时,易造成耗能严重的问题,为有效解决上述问题,基于线摩擦皮带机的主要运行工况,结合该种皮带机的主要布置方式,探讨在凹弧段与凸弧段皮带机的主要运行特征,研究带边增压方式,设计摩擦驱动增压装置,并对增压效果进行仿真模拟.结果表明,应用该摩擦驱动增压装置后,皮带机可基于皮带运行载荷情况,对承载带与传动带之间形成的摩擦力进行自动调整,很好地解决了长距离大运量皮带机现存的驱动力不足的问题,且有助于延长皮带机运行寿命,促进运输系统节能增效.
Abstract
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.
