Description
Technical field
The utility model relates to a kind of wire clamp structure that is used on the overhead transmission line conductor spacer, the protection gold utensil that belongs to electric power system, be specially adapted to that the bundle conductor in the ultra-high-tension power transmission line is carried out the interval and support, and have the conductor spacer revolution wire clamp of control overhead transmission line galloping.
Background technology
Various conductor spacers are arranged in the existing overhead transmission line, all fixing the gripping between its wire clamp and the lead, be mainly used in the antagonism lead and keep the sub-wire spacing of bundle conductor, reduce the corona generation and suppress the transmission line aeolian vibration because of the centripetal force that in-phase current produces.And at ice and snow weather, form icing on the overhead transmission line easily, because fixing the gripping limited reversing of lead between conductor spacer and the lead, thereby icing is eccentric often, forms a kind of airfoil type cross section, like this under the wind excitation of certain speed, cause waving of circuit generation low frequency, large amplitude, thereby cause transmission line flashover, tripping operation that gold utensil, insulator damage, conductor cord disconnection, even cause down accidents such as tower.Denomination of invention is " an overhead transmission line conductor spacer revolution wire clamp ", the patent No. is: the Chinese utility model patent of ZL200520122172.2 has been introduced a kind of overhead transmission line conductor spacer revolution wire clamp, it is characterized in that adopting first wire clamp to grip lead, and be to be rotationally connected with in the connecting hole of second wire clamp on the conductor spacer body with the lead center, therefore lead can longitudinally rotate, avoid eccentric icing, thereby reach the purpose of control transmission line galloping, but because the inner surface of the outer surface of first wire clamp and the second wire clamp clamping hole directly contacts when rotating, very easily wearing and tearing, and two wire clamps can not be relatively rotated by freezing being integral easily during ice and snow weather, lose anti-function of waving.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of overhead transmission line conductor spacer revolution wire clamp is provided, this wire clamp makes the lead that is clamped in wherein have rotational freedom, lead is reversed under the eccentric force of eccentric icing automatically and finally can't form eccentric icing, reach the purpose of control transmission line galloping, simultaneously this wire clamp should have not easy to wear, be difficult for being frozen into one by ice and snow and losing efficacy.
The technical measures of implementing above-mentioned purpose of the present utility model and adopting are as described below:
This conductor spacer turning spur folder comprises center wire clamp, pincerlike arm and several roller bearings composition; The center wire clamp is provided with the fixing pressuring line groove that grips lead, one end of pincerlike arm has two pincerlike folders to form a pincerlike button, by being installed in several inboard roller bearings of pincerlike folder the center line clamping is fixed in the pincerlike button, the center wire clamp can be in the pincer button of pincerlike arm is that rotate in the axle center with the lead, the other end of pincerlike arm is a handle shape structure, can be connected with spacer bracket.Wherein said roller bearing is made up of bearing and roller, and roller can rotate on bearing flexibly, and the number of roller bearing can be made as 4 or more usually.
In the utility model, as an optional embodiment, described several roller bearings evenly distribute inboard with the pincerlike folder of pincerlike arm, are connected with pincerlike folder sidewall by bearing, form to roll with the outer surface of center wire clamp by arbor wheel to be connected.In a preferred embodiment, the center line double-layered quilt is wrapped in the pincerlike button, thereby is difficult for being freezed by ice and snow and becomes one with the pincer folder and lose rotating function.
In the utility model, as another optional embodiment, described several roller bearings evenly distribute and the center wire clamp outside, are connected with center wire clamp outer wall by bearing, form to roll with the inner surface of pincerlike folder by arbor wheel to be connected.
In optional embodiment, described center wire clamp be designed to rotate " in " font, the inboard and roller bearing of described pincerlike button is designed to corresponding rotation " worker " font; Or described center wire clamp " worker " font of being designed to rotate, the inboard and roller bearing of described pincerlike button is designed to corresponding rotation " mouth " font, thus the traverse shaft direction that wire clamp edge, center is held can not be slided.
The beneficial effects of the utility model: this utility model is owing to adopted roller bearing as the jockey between center wire clamp and the pincerlike arm, adopt rolling friction to substitute sliding friction, avoided the skimming wear between center wire clamp and the pincerlike arm, prolonged useful life, and have and rotate flexibly, and adopt pincerlike clip pack to wrap up in the design of center wire clamp, then have and be difficult for being freezed the all-in-one-piece advantage by ice and snow.And the bundle conductor that utilizes said structure of the present utility model conductor spacer, because the center wire clamp can make the lead that is clamped in wherein have rotational freedom, make lead under the eccentric force of eccentric icing, finally can't form eccentric icing with center wire clamp FREE TORSION, thereby reach the purpose of control transmission line galloping, and have than existing product long service life, reduced and safeguarded and replacing, and had the higher advantage of reliability owing to being difficult for frozen inefficacy.
From above-mentioned improvement as can be known, compared with the prior art the technical program has following advantage:
1, substitute sliding friction with rolling friction, rotate more flexibly, it is little to wear and tear, long service life;
2, the center line double-layered quilt is wrapped in the pincer button that pincerlike folder forms, thereby is difficult for being freezed by ice and snow and becomes one with the pincer folder and lose rotating function.
3, wire clamp and pincerlike arm are aluminum alloy materials or nonmetallic materials, have energy conservation characteristic.
