Power grid engineering cable lower supporting device

Abstract

The invention discloses a power grid engineering cable lower supporting device which comprises a power grid tower column, a connecting transverse frame, a wire guide wheel set, a side supporting assembly and an upper fastening wire pressing assembly. The power grid tower column is vertically erected on the ground, connecting transverse frames are symmetrically fixed to the two sides of the upper end face of the power grid tower column and used for connecting and erecting power grid cables, and one end of each connecting transverse frame is provided with a wire guide wheel set; moreover, side supporting assemblies are symmetrically installed on the two sides of the upper end face of the power grid tower column, and the side supporting assemblies provide vertical lifting and bearing for the lower portion of the power grid cable. An upper fastening wire pressing assembly is further installed on the power grid tower column, and the left end and the right end of the upper fastening wire pressing assembly are erected between the wire guide wheel set and the side supporting assembly respectively and make contact with the upper end of the power grid cable in an abutting mode.

Description

technical field [0001] The invention relates to the technical field of power grid engineering equipment, in particular to a power grid engineering cable supporting device. Background technique [0002] The high-voltage power grid is an important component of the power system. Overhead transmission lines are a relatively common way in the construction of high-voltage power grids. By erecting wires in the air, the land occupation area in power grid erection can be reduced. Currently, high-voltage power grids are erected Most of the lines are overhead through the tower, and in the overhead power grid cable, due to the influence of the weight of the cable itself, the grid cable is prone to sinking, which makes the power grid cable loose at the connection of the tower, and at the same time, the long-term overhead effect Under normal circumstances, the cable will be stretched and deformed under the action of tension at the sinking place, and in severe cases, the power grid cable w...

[0002] The high-voltage power grid is an important component of the power system. Overhead transmission lines are a relatively common way in the construction of high-voltage power grids. By erecting wires in the air, the land occupation area in power grid erection can be reduced. Currently, high-voltage power grids are erected Most of the lines are overhead through the tower, and in the overhead power grid cable, due to the influence of the weight of the cable itself, the grid cable is prone to sinking, which makes the power grid cable loose at the connection of the tower, and at the same time, the long-term overhead effect Under normal circumstances, the cable will be stretched and deformed under the action of tension at the sinking place, and in severe cases, the power grid cable will be directly broken; and in the constantly changing environment, it is easy to produce stretching and shaking, which will affect the normal power transmission work; therefore, those skilled in the art A power grid engineering cable supporting device is provided to solve the problems raised in the above-mentioned background technology
