Description

Vibration damping anti-dance damping spring conductor spacer
Technical field
The utility model relates to the overhead transmission line technical field, is a kind of vibration damping anti-dance damping spring conductor spacer.
Background technology
The lead of overhead transmission line is because of be subjected to the influence of meteorological conditions such as wind, ice, low temperature throughout the year; the fatigue vibration of four direction takes place through regular meeting in lead, that is: the subspan oscillation of the aeolian vibration of vertical direction, transverse horizontal direction, along suitable the line of line direction vibrate, the waving of cross torsion direction.The vibration of the fatigue of the above-mentioned four direction of lead causes badly damaged to shaft tower, lead, gold utensil and insulator, make circuit powers failure of frequently tripping, and endangers the transmission line safe operation, causes great economic loss.
In superhigh pressure, UHV transmission line, four, six, eight division damping conductor spacers, two parallel wielded-proof device, eccentric hammer, off resonance pendulum, anti-dance whip or the like are installed usually, the aeolian vibration, subspan oscillation, the suitable line that are used for preventing lead vibrate, wave, to guarantee the safe operation of transmission line.Yet the above-mentioned vibration damping utensil of prior art can only effectively prevent the tired vibration of lead of one or two direction.Wherein: divide aeolian vibration and subspan oscillation that damping conductor spacer can only alleviate lead more; Two parallel wielded-proof device, eccentric hammer, off resonance pendulum, anti-dance whip etc. can only alleviate waving of lead.So far, do not see the fatigue vibration that can prevent overhead transmission line bundle conductor four direction as yet, that is: the subspan oscillation of the aeolian vibration of vertical direction, transverse horizontal direction, along suitable the line of line direction vibrate, the cross torsion direction wave the bibliographical information and the practical application of the vibration damping anti-dance damping spring conductor spacer that the vibration damping anti-dance is effective.
The utility model content
The utility model is based on the further investigation that spring, rubber property are carried out, and spring, rubber are vibration isolation, the damping means of using always.
The helical spring shock absorber that uses helical spring to make, because the stable mechanical property of spring both can design the very big spring of rigidity more exactly, also can design the very little spring of rigidity, can obtain the very high or very low vibration isolator of the natural frequency of vibration, spring has good shock-absorbing capacity for shock loading.
Rubber is a kind of viscoelastic material.Viscoelastic material has unique stress-strain behavior, makes it store lot of energy when stressed, and when unloading it is discharged; Because time effect, the load-deformation curve during unloading does not overlap with loading curve, thereby produce power hysteresis loss.This just makes elastomeric material promptly have the high polymer elastic large deformation to have bigger internal damping characteristic again, in the effect of performance favorable elasticity, is again good damping material, and this is the principle that the rubber-metal composite component is used for separating vibration and absorbs impact energy.
Rubber is comparatively ideal damping material, and vibration is had damping action.Rubber has very big linear pliability, almost can be stretched to break and do not lose its elasticity, and can bear alternate stress and be not prone to fatigue.Rubber is the same with water, and is compressible hardly, only produces strain behind the pressurized, but its constancy of volume.
The mechanical application scope of helical spring shock absorber is than rubber shock absorber broadness, and helical spring is less for the damping action of vibration, not as the such rapid damped vibration of rubber, therefore, has utilized spring for shock loading, oscillating load good shock-absorbing capacity to be arranged; Rubber is comparatively ideal damping material, and vibration is had the characteristic of damping action, and the framework of damping spring, heavy ball and conductor spacer is coupled together, and just can obtain the desirable vibration damping anti-dance effect to bundle conductor.
The purpose of this utility model is: provide a kind of rational in infrastructure, can prevent the fatigue vibration of overhead transmission line bundle conductor four direction, that is: waving of the suitable line vibration of the subspan oscillation of the aeolian vibration of vertical direction, transverse horizontal direction, suitable line direction, cross torsion direction, vibration damping anti-dance damping spring conductor spacer vibration damping anti-dance damping spring conductor spacer rational in infrastructure, that the vibration damping anti-dance is effective.
The purpose of this utility model is achieved through the following technical solutions: a kind of vibration damping anti-dance damping spring conductor spacer, it comprises that framework is connected with several wire clamps of five equilibrium, it is characterized in that: the body center at described framework is provided with heavy ball, and described heavy ball is connected with framework by at least two damping spring vibration isolators.
The structure of described damping spring vibration isolator is, comprise cylindrical shell, end at described cylindrical shell is connected with the carbine that dead axle rotates, be built-in with the piston type carbine that stretches out the described cylindrical shell other end at cylindrical shell, the upper end of one section piston type carbine in described cylindrical shell is coated with location-plate, be coated with Weight plate in its lower end, spring and damping rubber cover are set between location-plate and Weight plate, the damping rubber cover is enclosed within on the spring.
The damping rubber cover of described damping spring vibration isolator is the damping rubber piece, and described damping rubber piece places two ends or any end of spring.
Vibration damping anti-dance damping spring conductor spacer of the present utility model, owing to adopt and be provided with heavy ball at the body center of framework, heavy ball is by at least two structures that the damping spring vibration isolator is connected with framework, can make four as required, six, eight, ten binary fission conductor spacers, be specially adapted at superhigh pressure, in the UHV transmission line, fatigue vibration to the four direction of bundle conductor, that is: the aeolian vibration of vertical direction, the subspan oscillation of transverse horizontal direction, suitable line vibration along the line direction, the cross torsion direction wave the effect that all can bring into play the damped vibration energy, thereby reach best vibration damping anti-dance effect, suppress simultaneously phase conductor better, whiplash between the sub-conductor, has applied range, the user selects conveniently, compact conformation is reasonable, anticorona, cost is low, install and change conveniently, safe and reliable, life-span is long, to advantages such as working environment adaptability are strong.
