Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As depicted in figs. 1 and 2, the utility model provides a kind of conductors on quad bundled rotary type anti-bouncing damping conductor spacer, it comprises square framework 3, four summits of described framework 3 are fixedly connected with wire clamp, between any one wire clamp and framework 3, be provided for spacing clutch damping rubber device 6, the second stopping means 9 is set on any three limits on described framework 3, described the second stopping means 9 is long strip type positive stop lug boss, second stopping means 9 on framework 3 arbitrary limits is respectively two, and be arranged above and below, described framework 3 is provided with anti-dance device installing hole 11, described wire clamp comprises wire clamp main body 2, wire clamp gland 1, sliding sleeve 4 and grip damping rubber watts 5, described sliding sleeve 4 is embedded in wire clamp main body 2, described gripping damping rubber watts 5 is embedded in the sliding sleeve 4 of wire clamp, wire clamp gland 1 is by sliding sleeve 4, gripping damping rubber watts 5 closes in wire clamp main body 2, described wire clamp gland 1 is articulated and connected with wire clamp main body 2, and carry out shutoff by welding, described gripping damping rubber watts 5 is circular hole, and its Circularhole diameter and wire are suitable, grip sliding sleeve 4 the insides that damping rubber watts 5 is embedded in wire clamp, form the protective device of wire.Described sliding sleeve 4 forms circumferential slippage with wire clamp and coordinates, on described sliding sleeve 4, abrasion-proof stainless steel sheet is set, adopt and in the chuck of clamp, inlay stainless steel substrates formation sliding sleeve 4, flexibility ratio and resistance to wear while rotation with guarantee wire, described wire clamp afterbody arranges alignment pin 7, on described framework, four summits arrange ellipse spacing hole, and described alignment pin 7 coordinates with spacing hole clamping is spacing.
The necessary condition occurring from conductor galloping, mainly contains two aspects:
(1) on wire, should be covered with ice and snow, form and bring out the shape (as wing shape) of waving required icing accumulated snow.
(2) enough large wind, causes that the frequency of upper and lower vibration is consistent with the torsion cycle.
It is to utilize to grip damping rubber watts 5 coordinates formation free rotating mechanism with sliding sleeve 4 that the waving of the wire clamp that the utility model adopts suppressed principle, does not allow icing accumulated snow on wire form easily wave irregularly shaped.Because the wire of the rotatable gripping member of cable clip rotary type conductor spacer can turn round within the specific limits freely, also be that parton wire becomes can rotating " single conductor ", even if there is icing accumulated snow, wire utilizes the eccentric weight of icing accumulated snow also can reverse, can produce and reverse around self axis, thereby change the windward side of wire, so continuous icing, the result of constantly reversing, make wire form icing comparatively uniformly, it is circular that shape is tending towards, be difficult to form inhomogeneous shape, so that weaken the aerodynamic load acting on wire, make whole bundle conductor be difficult for waving.
