A Portable Rural Network Line Sag Adjustment Device

Abstract

The invention discloses a portable type rural-power-grid circuit sag adjustment device. The portable type rural-power-grid circuit sag adjustment device comprises a supporting rack. A winding drum is installed on the supporting rack, a rope is wound around the winding drum, a ratchet mechanism is installed at one end of the winding drum, the ratchet mechanism and the winding drum coaxially rotate, a large gear is installed at the other end of the winding drum, and the large gear and the winding drum coaxially rotate. A rope winding shaft is installed on the supporting rack, a small gear is installed next to the rope winding shaft, the small gear and the rope winding shaft coaxially rotate, the small gear is meshed with the large gear, a transmission mechanism is formed by the small gear and the large gear, a crank is fixedly installed on the small gear, and a fixed pulley used for guiding is installed on the supporting rack. The portable type rural-power-grid circuit sag adjustment device has the advantages that operation is easy, the dead load is light, the loading capacity is large, the sag adjustment accuracy is high, the construction intensity of workers is reduced, and the construction safety is guaranteed.

Description

technical field [0001] The invention is a portable sag adjustment device for rural power grid lines, which belongs to the field of operation, construction and maintenance of power distribution lines in rural power grids, and is especially suitable for remote mountainous areas where power equipment cannot be transported and when power distribution lines need to cross large rivers. vertical adjustment. Background technique [0002] Distribution lines are an important part of the power system. They are responsible for the arduous task of supplying power to urban and rural areas. Their safe and reliable operation will directly affect the development of the national economy and the quality of people's daily life. However, the distribution lines of the rural power grid have a wide area, many points, large areas, and uneven quality of equipment, which will bring great challenges to the operation and construction efficiency of the power grid staff; at the same time, most of the powe...

Problems solved by technology

[0003] For the sag adjustment of the line, the sag adjustment tools in the prior art are mainly concentrated in the field of transmission lines with higher voltage levels; or when adjusting the sag, most of them have complex methods, inconvenient operation, and inconvenient construction. Flexible, bulky tools, low sag adjustment accuracy and high cost, but currently there is still a lack of a practical method and a set of labor-saving, safe, reliable, and low-cost tools for sag adjustment of rural power grid lines
