摘　　要：特高压输电线路建设中组合格构式跨越架的组装中需要一种轻型化的起吊装置,为满足该需求,提出一种自提升型跨越架标准节起吊装置,该装置以钢管为主体,通过头部旋转帽对格构架的标准节进行起吊,并通过便携式牵引葫芦进行自提升,经过现场反馈,装置存在质量较大以及卡具安装不方便的问题,通过改变主体材质以减轻其质量,同时对其中的卡具进行改进,方便操作人员安装。In ultra-high voltage power line construction,the crossings quantity with express ways,railways and other power lines kept growing,in those crossings,assembly lattice frame need to be built.In this process,a light weight hoisting device is need.Therefore,we develop a type of self-lifting hoisting device for this occasion.Main body of this device is a hot-rolled steel tube,then,hoisting the lattice standard block is by the rotating head.The self-lifting function is achieved by portable winch.With the feedback from the field,we reduced the self-lifting mass of this device by changing the hot-rolled steel tube to aluminum alloy tube,we also modified the jig,to make the device more handy and compact.
