The invention discloses a pulley block device for ground wire maintenance operation and an application method thereof, and the pulley block device comprises a fixed sleeve unit, a clamping unit disposed on one side of the fixed sleeve unit, a movable sleeve unit disposed on the fixed sleeve unit, a lifting rope unit disposed on the fixed sleeve unit, and a pull rope disposed on the movable sleeve unit. The pulley block unit is arranged at the other end of the pull rope; contact between two lines can be effectively avoided, and friction between the ground wire and other lines is avoided in the lifting process of the ground wire; the device can extend to improve the protection range; besides, through the use of the pulley block, the distance between two lines can be ensured to be long enough, the crossed line can even be not powered off, at least the work of taking anti-wear measures on the crossed line lead or preventing the ground wire from falling to the ground or blocking the net on the working line is saved, the high-altitude operation risk and the labor intensity of operators are greatly reduced, and the working efficiency is improved. The working efficiency is improved.
本发明公开了一种导地线检修作业的滑轮组装置及其布施方法,包括固定套管单元、设置于固定套管单元一侧的夹紧单元、设置于固定套管单元上的活动套管单元、设置于固定套管单元上的提拉绳单元、设置于活动套管单元上的拉绳,以及设置于拉绳另一端的滑轮组单元;本发明可有效避免两条线路产生接触,在导地线抬升过程中,避免与其他线路产生摩擦;装置可以伸长,提升保护范围;此外,通过滑轮组的使用,可以保证两条线路的间距足够长,被跨越线路甚至可以不停电,至少节省了在被跨越线路导线上落实防磨损措施或防落导地线至地面或在工作线路上封网等作业,极大降低高空作业风险及作业人员劳动强度,提升工作效率。
