《提升运输机械》[1]第八章中推荐确定多绳提升机主导轮和导向轮的间距的公式为: h_i≥(D-S)ctgθ+0.5 (8-8) 式中h_i——主导轮与导向轮之间的垂直距离 D——主导轮直径 S——提升钢丝绳的间距θ——主导轮和导向轮间的钢丝绳与垂线的夹角。在h_i确定后,可用下式求出实际的θ值: θ=sin((~(-1)0.5D+0.5D_d)/(h_j~2+b~2)~(1/2))-tan~(-1) b/h_j(8-9) 式中Dd——导向轮直径 b——主导轮与导向轮之间的水平距离
The formula for determining the distance between the guide wheel and the guide wheel of the multi-rope hoist is recommended in Chapter 8 of “Hoisting and Conveying Machinery” [1]: h_i≥ (DS) ctgθ + 0.5 (8-8) where h_i-- The vertical distance between the guide wheel D - the diameter of the main guide wheel S - to enhance the spacing of the rope - - the angle between the main guide wheel and the guide wire between the guide wheel and the vertical. After the determination of h_i, the actual value of θ can be found by the following formula: θ = sin (- (-1) 0.5D + 0.5D_d) / (h_j ~ 2 + b ~ 2) ~ (1/2)) - tan ~ (-1) b / h_j (8-9) Where Dd - guide wheel diameter b - the main guide wheel and the guide wheel between the horizontal distance
