Description
Technical field
The present invention relates to vibration isolator, particularly a kind of overhead transmission line protection prevents conductor vibration, the vibration isolator of waving, and more particularly, is a kind of damping spring stockbridge damper.
Background technology
Lead in the transmission line is because of be subjected to the influence of meteorological conditions such as wind, ice, low temperature throughout the year; tired vibration takes place through regular meeting in lead, has: the aeolian vibration of vertical direction, the subspan oscillation of horizontal direction, along suitable the line of line direction vibrate, the waving etc. of cross torsion direction.Above-mentioned these vibrations cause badly damaged to shaft tower, lead, gold utensil and insulator, make circuit powers failure of frequently tripping, and endanger the transmission line safe operation, cause great economic loss.
At present, in superhigh pressure, UHV transmission line, stockbridge damper, damping conductor spacer, two parallel wielded-proof device, eccentric hammer, off resonance pendulum, anti-dance whip or the like are installed usually, be used for preventing lead vibration, wave.Yet, in the circuit running, prevent that the vibration of lead, the effect of waving are all undesirable, still occur conductor vibration often, wave accident, the safe operation of harm transmission line.
Summary of the invention
The present invention 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, with spring, damping rubber, the Weight plate damped vibration energy rapidly that is connected, can realize vibration damping, anti-dance function to lead.
The objective of the invention is: provide a kind of rational in infrastructure, make transmission line wire vibration damping, the effective damping spring stockbridge damper of anti-dance.
The objective of the invention is to realize: a kind of damping spring stockbridge damper by following scheme, it is characterized in that: it comprises the damping spring vibration isolator, wire clamp, the structure of described damping spring vibration isolator is, comprise cylindrical shell, be built-in with piston rod at cylindrical shell, on the piston rod, the lower end all is coated with location-plate, spring and damping rubber cover are set between location-plate, the damping rubber cover is enclosed within on the spring, the structure of described wire clamp is, the upper end that comprises wire clamp main body and wire clamp gland is hinged, the wire clamp main body, the upper end of the piston rod of the lower end of wire clamp gland and damping spring vibration isolator is connected.
Bottom in the cylindrical shell of described damping spring vibration isolator is equipped with Weight plate.
Bottom at the cylindrical shell of described damping spring vibration isolator is provided with osculum.
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.
Between the wire clamp main body of described wire clamp and wire clamp gland, be provided with the anti-slip rubber pad of clamping lead.
Damping spring stockbridge damper of the present invention is suspended on by wire clamp on the lead of transmission line, and the spring of damping spring vibration isolator can shock absorbing load, oscillating load; The damping rubber cover of damping spring vibration isolator or damping rubber piece are mainly to having vibrated damping action; Weight plate in the cylindrical shell will change parameters such as the moment of inertia of lead and torsional rigidity; Spring, damping rubber cover or damping rubber piece, Weight plate organic assembling are coupled together damped vibration energy rapidly, have rational in infrastructure, make transmission line wire vibration damping, anti-dance effective, cost is low, install and change conveniently, safe and reliable, long working life is to advantages such as working environment adaptability are strong.
