煤矿掘进工作面JD-11.4绞车一次牵引矿车数计算说明

1、JD-11.4 绞车一次牵引矿车数计算说明一、基本参数1、掘进工作面JD-11.4型调度绞车参数：牵引力10KN、钢丝绳直径 12.5mm、平均绳速 0.73m/s、最大绳速1.033m/s、最小绳速 0.433m/s、容绳量 400m。2、配用钢丝绳6X19X12.5参数：钢丝绳直径d= 12.5mm,总断面积57.27mm2,钢丝绳单位长度重量Pb = 0.54kg/m,钢丝绳公称抗拉强度 170kg/mm2,钢丝绳破断拉力总和 Qp= 9730kg。3、U型固定车箱矿车参数：容积1.1 m3、名义载重量1t;空车自重 Q = 618kg、单车煤重量 Q煤=1000 kg、单车研重量 Q研

2、石=1700 kg、单车煤研重量 Q煤研=1350 kg。4、 7.5m3 V 型翻斗式矿车参数：名义载重量0.7t、最大载重量1.2t、空车自重 Q= 514kg、单车煤重量 Q煤=700 kg、单车研重量 Q研石= 1190 kg、单车煤研重量 Q煤研=945kg。二、 JD-11.4 型调度绞车一次牵引矿车数计算：JD-11.4 型调度绞车一次牵引矿车数主要是根据钢丝绳最大拉力确定，对钢丝绳实际拉力的限制条件主要有三个：1 、安全系数的限制根据煤矿安全规程规定，钢丝绳的安全系数应A 6.5,钢丝绳实际所受最大拉力应小于其破断拉力总和Qp 的 6.5倍，应为：Fmax = Qp / 6.5

3、= 9730kg / 6.5= 1497kg= 14670N。2、绞车牵引力的限制条件JD-11.4型调度绞车最大牵引力为 F额=10KN = 10000N3、功率的限制条件绞车的实际功率应不大于其额定功率P额，即：NVP额N= FmaxV i.ivp 额= ”4KW 102V绞车最大绳速，取 1.033m/s;刀一一绞车工作效率，取 85%;则有F max =P额 102V 1.1_ 11.4 102 85%1.033 1.1= 869823N3、绞车一次牵引矿车数计算由上述可知，JD-11.4型调度绞车最大钢丝绳牵引力应为 Fmax=10000N则确定JD-11.4型调度绞车一次牵引最大矿

4、车数：Fmax刁n (Qr+Q) (sinB+hcosB ) +PbL (sinB+fzcosB ) x 1.1轨道最大工作坡度，取值范围 020° ,可分别验算;L 钢丝绳工作长度，取 300 m;f1矿车阻力系数，取0.015;f2钢丝绳阻力系数，取0.20;Qr为单车煤或研石或煤研的重量，可分别验算；n煤或研石或煤研的数量；1.1备用安全系数。计算结果如下:JD-11.4型调度绞车一次牵引U型固定车箱矿车（煤什车）最多数目计算表n(Qr+Qsin 6 +f 1 cos 6sin 6 +f 2cos 6(Qr+Q (sin 6 +f 1cos 6 ) gPbL (sin 6 +f
