Description

Automatic-installation binary split conductor spacer and installation method Technical Field The invention relates to the field of overhead installation of wires, in particular to a binary split wire spacer capable of being automatically installed and an installation method. Background Spacer bars are devices mounted between adjacent wires, primarily to maintain the spacing between wires and reduce wire vibration. Most of the existing spacing bars are installed at high altitude manually, so that the risk coefficient is high, and the technical difficulty and the labor intensity are high. For the two-split conductor, the spacer only needs to separate the two conductors, and the structure is relatively simple, so the two-split conductor spacer with automatic installation is developed on the market and is generally installed by a robot or an unmanned aerial vehicle. However, due to the limitation of the field of view of the overhead operation (for example, the blocking of the field of view by a wire, a cross arm, a jumper wire, etc.), the positioning accuracy is poor, and sometimes the spacer cannot be triggered due to the installation dislocation, so that the installation error is caused. Sometimes, when the spacer is loosened after installation, misjudgment often occurs, so that the motor of the robot or the unmanned aerial vehicle is overloaded and damaged. Meanwhile, the existing automatic installation of the spacer is limited to be fixed on the wire, but the spacer does not have an anti-loose effect, and in seasons with more wind, the phenomenon that the spacer slides from the wire often exists, so that the wire cannot be separated at a fixed point.
