Multi-functional distribution line rod top maintenance support bar

Abstract

The invention provides a multi-functional distribution line rod top maintenance support bar. The support bar comprises a rocking handle, a bevel gear 1, a bevel gear 2, a nut, a lead screw, an extension pipe, an insulation fulcrum bar, a U-shaped fork, an irradiation lamp, a pulley, a rotating shaft, a bearing 1, a gearbox, an end cap and a support seat. The rocking handle is fixedly connected to the bevel gear 1. An upper portion of the bevel gear 2 is fixedly connected to the nut. The lead screw and the nut are connected through a rectangular thread. The lead screw is provided with the extension pipe. An upper end of the extension pipe is connected to the insulation fulcrum bar. Through arranging the irradiation lamp, the extension pipe, the bevel gear 1 and the bevel gear 2, usage functions are perfect, a height adjusting amount is increased, the support bar is stable and reliable, night usage and operation are convenient, the support bar is easy to carry, a usage range is enlarged, and popularization and usage are convenient.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a multifunctional power distribution line top maintenance support rod. Background technique [0002] The top of the electric column of the 10KV distribution line supports the wires through the pillars and insulators. Due to the constant swing of the wires and the wind and rain, the pillars and insulators are easily deformed and damaged, and timely maintenance and replacement are required. In the past, the replacement of such components required a power outage, which affected users' electricity consumption and caused great economic losses. In recent years, with the application of many new types of equipment, it has been possible to carry out live maintenance. But, when changing prop or insulator, also will support wire by people with insulating rod, and wire weighs 100 jins, lifts laboriously, has both increased manpower burden, is unsafe again.
