1、門架吊裝計算
1.1、鋼絲繩受力計算:
名稱 門架吊裝
重量 140.0
AB = 2730 CD = 2730
al = 1365 el = 1365
h = 9600 f = 0
c = 1687 d = 1687
水平傾斜角(α):0.0度
鋼絲繩長度:EA = 9842
EB = 9842
EC = 9842
ED = 9842
鋼絲繩張力:Fea = 35.9
Feb = 35.9
Fec = 35.9
Fed = 35.9
夾角:∠AEB = 15.9
∠BEC = 19.7
∠CED = 15.9
∠DEA = 19.7
鋼絲繩L1鋼絲繩選用6*37-Φ66-1770(FC)
2.2吊耳受力計算:
鋼絲繩張力為35.9t
a)頂部截面積S=3.5x(12.5-5.5)+2x2x(11-5.5)=46.5(cm2)
剪切強度:τ=P/S=35.9x103/46.5=772(kg/cm2)<[τ]
B)吊耳焊縫計算:按雙面角焊縫計算(對應(yīng)焊接的橫梁筋板為12mm)
焊縫應(yīng)力:σ=P/(0.7δxΣL)
=35.9x103/(2x0.7x1.2x51)=37200/85.68
=419.1(kg/cm2)<[σ]
2、轉(zhuǎn)盤吊裝計算
2.1 鋼絲繩受力計算:
名稱 有轉(zhuǎn)盤配重吊裝
重量 307.0
AB = 3400 CD = 3400
