Abstract

The invention discloses an overhead transmission line grounding line repair device and repair method. The device comprises a wining component, a mobile component, and an obstacle avoiding component, wherein the winding component comprises two winding disks capable of moving spirally in opposite directions, the winding disk is provided with an opening clamped in a grounding line and a winding holematching the grounding line, the winding hole is externally provided with carrying holes carrying a preformed armor rod, the mobile component comprises a drive wheel, the drive wheel is provided witha concave clamp slot matching the grounding line at the periphery and is installed on the grounding line to drive the mobile component to move, and the obstacle avoiding component keeps the winding component far from the grounding line. The device has the advantages that the preformed armor rod can be carried and wound, the broken grounding line can be automatically repaired more efficiently; thedevice can work when being alive, so that power off repair cost is lowered; the operation is safe and efficient; and tension wheels tension the grounding line to cooperate with the drive wheel to helpthe repair device climb, so that the overhaul capability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of electric wire maintenance, in particular to a repairing device and a repairing method for ground wires of overhead transmission lines. Background technique [0002] Damage and broken strands of the ground wire are common line accidents on high-voltage transmission lines. According to the "Guidelines for Repairing Conductors and Ground Wires of Overhead Transmission Lines" (the Electric Power Industry Standard of the People's Republic of China DL / T1069-2016), pre-twisted wire repair strips are generally used to repair ground wires, and pre-twisted wire repair strips exist With the advantages of safety and beauty. But the disadvantages are also obvious. The pre-twisted wire repair strips need to be installed one by one during installation. The winding direction of the repair strips is strict, and the length of the repair strips is long. The operators generally use the ladder to repair the wires. The range...
