一种拉线下拔装置
本专利技术属于输电装置领域,特别是涉及一种拉线下拔装置。
技术介绍
电线路杆塔拉线装置,其主要作用是辅助杆塔基础稳固杆塔,增加杆塔的结构强度,同时当杆塔出现小幅度偏斜后,及时调节,使杆塔正直,确保其正常受力,保证杆塔正常工作。传统的拉线装置,由钢绞线、上、下拔、拉线棒、拉线金具(包括拉线环、拉线U形环)、拉线盘组装构成。安装时:用拉线U形环将拉线盘与拉线棒进行联接,并预埋好,将钢绞线弯折并与上、下拔装配连接形成拉线,拉线上端通过拉线环固定于杆塔上,拉线下端则由下拔直接与拉线棒连接,至此形成杆塔完整的拉线装置。其中:拉线棒、个别拉线金具(连接U形环)、拉线盘为地埋部分;拉线棒端部、上、下拔、钢绞线、拉线环为地上部分。传统拉线装置存在诸多弊端:如,易锈蚀、断裂;拉线下拔需要具备调节拉线松紧度的功能;且由于上述构件均为金属材质制成,不法之徒为获取非法经济利益,不惜铤而走险,盗割破坏线路杆塔拉线棒的地面外露部分及拉线下拔、钢绞线,严重危及输电线路杆塔的可靠运行;另外,传统杆塔拉线装置还存在手工制作工艺复杂、安装工序烦琐等缺点,且手工制作工序无法保证质量, ...
