一台皮带输送机,当由水平输送变成倾斜输送时,中间必须有一段曲线区作为过渡,这段过渡的凹弧形曲线习惯上称为“起升曲线”,也叫“抛高曲线”。设计时,一般将这段曲线近似地看成正圆弧曲线,并把圆弧半径“R”作为该曲线的曲率半径。我库80年修造一区地下卸粮坑时,为了使卸粮坑的输送机与原建去粉厂的地下输送线 A belt conveyor, when transfered from horizontal to inclined, must have a section of curve in the middle as a transition. The concave curve of this transition is customarily referred to as “lift curve”, also called “throw-up curve” . Design, the curve will generally be regarded as a normal arc curve, and the arc radius “R” as the radius of curvature of the curve. 80 years to build a library in my area underground grain barrow, in order to unload grain conveyor pit conveyor and the original construction to the underground conveyor line
