Design and Application of the Butt Auxiliary Device for the Erection of Steel Tower Using Helicopter

Abstract:

The erection construction technology of steel tower of overhead transmission line using helicopter has higher requirements to the butt auxiliary device. According to the GE1 steel tower of the QingZang AC/DC interconnection project Geermu converter station earthling line, the butt auxiliary device is developed. The butt auxiliary device includes a guiding device, horizontal-direction caging device and vertical-direction caging device and solve the problems as follows limiting in air, docking, perching and temporary supporting. The successful engineering application show that the butt auxiliary device is safety and reliable and has perfect function, simple structure and convenient installing and removing. This provides reference for the design of the butt auxiliary device to other types steel tower of transmission line.
