一种密间隔电位检测系统用放线装置
本技术涉及埋线管道检测设备
,具体涉及一种密间隔电位检测系统用放线装置。
技术介绍
在埋地管道的密间隔电位检测过程中,线盘末端即线盘最内层铜线线头接在检测仪器上跟随人员同步运行,线盘最外层铜线接头连接到管道某一位置,之后人员沿管道正上方使用仪器对管道进行检测,期间铜丝靠放线器进行放线,在放线期间需保持铜丝的电连续性即铜丝中途不能断开。现有的密间隔电位检测系统用放线装置中的线盘为固定线盘,铜丝缠绕在线盘上,通过轴向方向拉扯铜丝,靠拉力使铜线从线盘上脱离进行工作,但是轴向方向受力与铜丝缠绕方向垂直,铜丝脱离线盘过程中铜丝会摩擦线盘侧边使铜丝脱离过程受阻,导致铜丝受力过大断开。
