The invention provides a construction scheme of an engineering helicopter in high-voltage line tower transportation. The construction scheme comprises the steps that construction preparation is carried out; a hoisted tower section is assembled; a set of butt joint auxiliary system is installed on each of the hoisted tower section and an in-place tower section; the outer sides of every two adjacenthorizontal limiting devices are connected with limiting ropes; the hoisted tower section is suspended below the belly of the helicopter by using a suspending device, and then the hoisted tower section is suspended to a position near the in-place tower section; the engineering helicopter adjusts the direction of the hoisted tower section and falls to a certain height away from the ground, and ground auxiliary personnel connect control ropes to connecting plates; the engineering helicopter hoists the hoisted tower section to the position above the in-place tower section, and the in-place centeris found accurately and the hoisted tower is suspended under the action of the butt joint auxiliary system; the ground auxiliary personnel tighten the four control ropes, so that the four edges of the hoisted tower section and the in-place tower section are aligned in parallel in an overlooking plane; and the tower crane section smoothly slides into the installation position by means of the buttjoint auxiliary system, and the hoisted tower section is accurately in butt joint with the in-place tower section, and finally the hoisted tower section falls on a platform of a vertical limiting device.
本发明提供一种工程直升机在高压线塔运输方面的施工方案,包括:施工准备;组装被吊塔段;在被吊塔段和已就位塔段各安装一套对接辅助系统;在相邻两水平限位装置的外侧连限位绳;使用吊挂装置将被吊塔段悬挂在直升机机腹下方,然后将其吊运至已就位塔段附近;工程直升机将被吊塔段调整好方位、落下至距地面一定高度,地面辅助人员将控制绳连接在连接板上;工程直升机吊起被吊塔段至已就位塔段上方,在对接辅助系统作用下找准就位中心并悬停;地面辅助人员收紧四根控制绳,使被吊塔段与就位塔段在俯视平面内四边平行对齐;吊塔段借助对接辅助系统顺畅滑入安装位置,被吊塔段与已就位塔段准确对接,最终被吊塔段落至垂直限位装置的平台上。
