1、 I 摘要摘要 带式输送机是连续输送机械的一个类别，是以输送带作为牵引构件和 承载构件,利用托辊支撑， 依靠传动滚筒与输送带之间摩擦力传递牵引力的 连续输送设备。它可将各种粉状、颗粒状及块状等散状物料，在一定的输 送线路上，从装载地点到卸载地点以连续物料流的方式进行输送，不仅对 工业企业的内部输送起着重要作用，同时对其外部输送也起着重要作用。 由于投资少、运营费低、可以进行物料的长距离输送等原因，在某些场合 可以代替铁路运输及公路运输，已成为工业企业生产中不可缺少的输送设 备。 近 20 年来， 由于带式输送机与其他输送机械相比具有不可比拟的优点， 我国的带式输送机有突飞猛进的发展，比较突出的

2、特点是应用的带式输送 机输送量大、单机长度大、电动功率大、启动制动技术水平有很大提高。 由于带式输送机运营费用低，特别在当前我国燃油供应紧张、依赖进口的 数量大、油价高的情况下，使带式输送机的应用范围更加宽广。其优点主 要表现在以下方面：结构简单，节能与经济性，输送物料范围广，输送距 离长，输送能力大、生产效率高，线路布置灵活、适应性强，提升角度大， 受料和卸料灵活，安全可靠性高，环保性能优越，操作简单、容易实现程 序控制。 关键词关键词：带式输送机 ;上运;电控系统 II Abstract Belt conveyor is a type of continuous conveyor is a

Due to low investment, low operating costs, can be transp

5、orted long distances and other reasons for material, can replace the railway transport and in some the occasion Road transportation has become an indispensable transportation equipment in the production of industrial enterprises.In the past 20 years, because of the belt conveyor and other transporta

6、tion machinery has incomparable advantages, Chinas belt conveyor have developed rapidly, the more prominent features is the conveyor volume application, single length, electric power, braking technology level has greatly improved. Due to the band conveyor low operating costs, especially in the current Chinas fuel supply, the number of dependence on imports, high oil prices under the condition that the application scope of the belt conveyor is broader. Its advantages are mainly in the followin
