1、摘要随着大倾角带式输送机向大角度、长距离、高速度、大功率方向发展，除驱动装置外，张紧装置是保证输送机正常启动、运行、制动、和停车的不可缺少的重要部件之一，直接影响带式输送机的安全可靠性和稳定性。大倾角皮带输送机可沿水平或倾斜线路运行，一般使用光面输送带，靠所运物料与输送带之间的摩擦力，带动物料一起运行，因而工作倾角受限制。向上一般不超20，向下的倾角还要小些。为了能在更大的倾角上使用，节省材料及节省占地面积，增大皮带输送机倾角有着重要的意义。本设计从大倾角皮带输送机的整体结构出发，对大倾角皮带机结构作了详细的论述。在皮带机起动阶段，能够在准确的时间开启皮带机；启动完毕后正常运行。此设计的特点是
