摘要
货运施工索道在输电线路工程的物料与塔材运输中起着十分重要的作用。文章根据输电线路地形特点,对比了现有几种索道形式以后,提出适合输电线路建设的双承重索、单牵引索的工作索布置方案。采用抛物线理论和悬链线理论2种计算方法,互为校核和补充。在中挠系数取0.02～0.06时,2种理论计算结果误差率满足工程要求。
Construction cargo cableway plays an important role in transmission line construction and tower component conveyance. Based on terrain characteristics of transmission lines, this paper compares existing cableway types and put forward working cable arrangement that adopts dual bearing cable and single pulling cable. Two computation methods, parabola theory and Catenary theory, are used to check and complement each other. When the center deflection coefficient is chosen as 0.02-0.06, computation errors from both methods meet engineering requirements.
