Abstract
A kind of transmission line wire vibration damping conductor spacer belongs to the electric power protection gold utensil of power transmission line engineering.The shortcoming that mainly wind that causes because of icing, ice-melt of the existing conductor spacer existence of solution vibrates, the inferior conductive line surfaces that is held apart from vibrating, easily making is worn.The utility model comprises that several have the support arm of wire casing, and the upper frame of clamping support arm and underframe, projection has been played in the outside that it is characterized in that said support arm link, inside has and is double-deck cavity, be provided with in the cavity two-layer totally eight by hollow cross axle elastic cylinder spaced apart from each other, the inboard of said upper frame and underframe is equipped with the retaining stake that matches with projection, and is connected with the link of support arm by bolt.The utility model is by adopting elastic cylinder and projection, retaining pilework, can recover the displacement angle that takes place between the support arm voluntarily, thereby reaches the purpose of vibration damping, prevents natural phenomena such as deice jump, wave, and is anti-corona and locking, but and guardwire not impaired.
Description
Technical field
The utility model belongs to the electric power protection gold utensil of power transmission line engineering.
Background technology
Conductor spacer is to be used for branch folder lead in the power transmission line engineering, existing conductor spacer is owing to be the rigidity structure, under external force, especially the wind vibration that causes because of icing, ice-melt at high height above sea level, heavy icing area, inferior to vibration easily makes the conductive line surfaces that is held be worn.
Summary of the invention
The purpose of this utility model is the transmission line wire vibration damping conductor spacer that a kind of wind resistance pendulum, low wearing and tearing are provided at above-mentioned deficiency.
The utility model is achieved in that and comprises that several have the support arm of wire casing, and the upper frame of clamping support arm and underframe, projection has been played in the outside that it is characterized in that said support arm link, inside has and is double-deck cavity, be provided with in the cavity two-layer totally eight by hollow cross axle elastic cylinder spaced apart from each other, the inboard of said upper frame and underframe is equipped with the retaining stake that matches with projection, and is connected with the link of support arm by bolt.
Resilient sleeper-bearing is equipped with in the inboard of above-mentioned wire casing, and this resilient sleeper-bearing is fastened and connected by button column on it and the button hole on the wire casing.
The utility model employing elastic cylinder and projection, retaining pilework, in when, between support arm angle displacement taking place, owing to being squeezed, elastic cylinder rebounds, and under the effect of projection and retaining stake, can recover displacement angle, thereby reach the purpose of vibration damping, prevent natural phenomena such as deice jump, wave, anti-corona and locking; Adopt the resilient sleeper-bearing structure in the wire casing, and auxilliary button column and button hole be fastened and connected, but both guardwire was not impaired, also can make resilient sleeper-bearing easy for installation, firm.
