With the continuous deepening of rural construction, as the basic guarantee for agricultural activities and rural life, distribution network overhead lines play an important role in rural power grids. In recent years, our country has strengthened the construction of rural power grids. However, with the continuous expansion of the scale of rural power grids, the coverage of overhead lines has become wider and wider, and various line reconstruction and construction operations have become more and more frequent to meet the growing power load of rural power grids. .

The transformation of the power grid will inevitably involve the erection of new poles and the installation of related components. During the construction of new vertical poles, there are certain limitations in hoisting operations such as erecting cross arms on the top of the poles and assembling hardware, so they are often The method used is to use a rope sleeve to fix it on the top of the pole, and then install a pulley on the rope sleeve to lift various tools and materials. Usually the installation position of the rope sleeve and pulley is generally the position where the cross arm is installed at the top of the pole. However, when the cross arm is lifted, the force of the rope sleeve will cause the fixed point of the rope to slide down on the pole, thus occupying the position where the cross arm is installed. ; After the cross arm is hoisted to the top of the pole, it is necessary to re-adjust the position of the rope sleeve before installing the cross arm, which makes the installation process troublesome and laborious; and there is also the danger of the safety belt slipping from the top of the pole during installation, so the currently used The method of hoisting cross arms and other materials with rope sets and pulleys has a great impact on subsequent installation work.
