摘要:
本发明公开了一种适用于特高压电线张力放线的方法:(1)在牵引场设置四台“二线牵张一体机”作为主牵引设备,张立场设置四台“二线张力机”,铁塔每相悬挂两套相互独立的放线滑车;(2)前期展放8根导线牵引绳,每4根牵引绳分别通过一套放线滑车上的四个辅助滑轮,并以“一牵1”的方式牵放八分裂子导线,通过四台“二线张力机”和四台作为牵引机的“二线牵张一体机”实现导线同步展放;(3)在八分裂子导线到达放线滑车时,利用触发走板触动放线滑车上的触发机构,使同一滑车上的辅助滑轮下降到低于放线滑车的主滑轮,使八分裂子导线通过两套放线滑车上的主滑轮被同步展放。这种方法无需大吨位主牵引设备即可满足特高压电线张力放线要求。
摘要(英):
The invention discloses a tension wire-laying method applies to ultra-high voltage electric wires: (1) four are arranged in a hauling field as main hauling devices, four are arranged in a tension field, two sets of wire-laying tackles that are independent to each other are hanged on the iron tower per phase; (2) in the earlier period 8 lead traction ropes are laid, every four traction ropes go through four auxiliary sliding wheels arranged on one set of wire-laying tackle and haul and lay an eight-multiple lead in theform of , and realize synchronous laying of leads through four and four as hauling devices; and (3) when the eight-multiple lead reaches the wire-laying tackle, a trigger running board touches a trigger mechanism on the wire-laying tackle, which is used to make the auxiliary sliding wheel on the same tackle drop to the position lower than the main sliding wheel of the wire-laying tackle, and make the eight-multiple lead be synchronously laid by the main sliding wheels on the two sets of wire-laying tackles. The method can meet the tension wire-laying demand of ultra-voltage electric wires without long ton main hauling equipment.
