Background Technique
[0002] With the continuous development of China's social economy and the increasing demand for electricity, China's power grid infrastructure construction industry has also entered a high-speed development mode. At the same time, with the continuous improvement of people's living standards, people's dependence on electricity is becoming stronger and stronger, and electricity is indispensable in all aspects of daily life, transportation, etc.
[0003] When constructing overhead lines and crossing power lines, railways, highways, etc., due to the time limit of coordination and cooperation among multiple departments such as important loads of crossing power lines, important transportation arteries, and railways, the construction of overhead lines has to be carried out in sections. During the construction process, it is often necessary to carry out over-pulley temporary anchoring at straight towers. Although over-pulley temporary anchoring solves the problem of discontinuous wire stringing, it cannot solve the problem of conductor whipping. In order to avoid conductor whipping caused by over-pulley temporary anchoring and damage to the conductor, this special tool was made according to the actual situation on site.
[0004] During the construction of overhead lines, due to the limitation of crossing time, it is necessary to complete the wire stringing construction task in sections. Due to various limitations such as terrain and investment costs, there will inevitably be situations of over-pulley temporary anchoring, and this tool cleverly solves the problem of whipping and damaging the conductor after over-pulley temporary anchoring.
