Abstract

The invention discloses a safety protection device for single-loop electrified pole erecting operation, which comprises a first insulating support rod and a second insulating support rod, and is characterized in that the first insulating support rod is arranged between a side-phase wire and a middle-phase wire in three-phase wires in a staggered manner, and the first insulating support rod is provided with a first locking piece for fixing the side-phase wire and the middle-phase wire respectively; the second insulation supporting rod is arranged between the two side phase wires, and second locking pieces used for fixing the two side phase wires respectively are arranged on the second insulation supporting rod; the first insulation supporting rod and the second insulation supporting rod are integrally arranged in a triangular shape in the direction parallel to the axial direction of the three-phase wire. The two side-phase wires and the middle-phase wire are respectively opened through the first insulating supporting rod, then the two side-phase wires are horizontally opened through the second insulating supporting rod, the distance between the three-phase wires is stable through the first insulating supporting rod and the second insulating supporting rod, and the middle-phase wire does not need to be pulled open through an insulating rope. And the safety of operators is greatly improved.

Description

technical field [0001] The invention relates to the technical field of live work, in particular to a safety protection device for single-circuit live pole work. Background technique [0002] In the live pole operation project, it is necessary to ensure the safe distance between the three-phase wires, but before the operation, it is necessary to use the insulating rope to pull the middle phase wires apart to ensure the safe distance between the side phase wires and the middle phase wires, but in In actual operation, the middle-phase conductor pulled by the insulating rope is easily shaken by external influences, causing the distance between the middle-phase conductor and the side-phase conductor to change, resulting in high operating risks for operators. Contents of the invention [0003] Aiming at the current single-circuit live work, the middle-phase wire pulled by the insulating rope is easily shaken by external influences, causing the distance between the middle-phase w...
