9、59Acknowledgements60References61第1章 绪论1.1 国内外带式输送机的发展现状带式输送机是连续运输机的一种，连续运输机是固定式或运移式起重运输机中主要类型之一，其运输特点是形成装载点到装载点之间的连续物料流，靠连续物料流的整体运动来完成物流从装载点到卸载点的输送。目前带式输送机已广泛应用于国民经经济各个部门，近年来在露天矿和地下矿的联合运输系统中带式输送机又成为重要的组成部分。主要有：钢绳芯带式输送机、钢绳牵引胶带输送机和排弃场的连续输送设施等。这些输送机的特点是输送能力大(可达30000t/h)，适用范围广(可运送矿石，煤炭，岩石和各种粉状物料，特定条件下也可以运人)，安全可靠，自动化程度高，设备维护检修容易，爬坡能力大(可达16)，经营费用低，由于缩短运输距离可节省基建投资。现阶段，带式输送机的发展趋势是：大运输能力、大带宽、大倾角、增加单机长度和水平转弯，合理使用胶带张力，降低物料输送能耗，清理胶带的最佳方法等。我国已于1978年完成了钢绳芯带式输送机的定型设计。国外带式输送机技术的发展主要表现在两方面：（1）带式输送机的功能多元化，应用范围扩大化，如高倾角带式输送机、管状带式输送机、空间转弯带式输送机等各种机型；（2）带式输送机本身的技术与装备有了巨大的发展，尤其是长距离，大运量，高带速等大型输送机已成为其发展的主要方向。目前，世界上单机运距
