摘　　要：内悬浮外拉线抱杆是浙北—福州特高压交流线路工程中组立高塔所用的特种起重机械,此抱杆通过承托绳和铁塔连在一起。本文针对某44m钢结构格构式变截面抱杆,在不同倾斜角度下进行有限元模拟分析计算,得到外拉线、承托绳拉力及抱杆的应力和位移。结果表明,拉力、位移和应力都随着倾斜角度的增加而增大,据此内悬浮外拉线抱杆的最大倾斜角度取为10°。The Inner suspended and outer guyed holding pole was used in the North Zhejiang-Fuzhou UHV AC power transmission line engineering,which is a special crane made for assembling electric transmission towers.The holding pole was connected with a transmission tower with supporting ropes.For one 44 m lattice type variable crosssection holding pole,the structure was analyzed at the different inclination angle by the finite element method in this paper.The tension of outer guys and supporting ropes was calculated.The displacement and stress of the holding pole were also obtained.The results showed that the tension,displacement and stress increased with the increasing of the inclination angle.Based on this,the maximum inclination angle of the holding pole should be within 10°.
