Abstract

The utility model relates to a single wire composite alternation spacing stick which comprises a core rod and ear slot wire clamps arranged at two ends of the core rod. A big umbrella skirt and a small umbrella skirt which are arranged on the circumferential wall of the core rod and extend in radial direction are distributed at intervals in mutually staggered mode. Each ear slot wire clamp comprises a wire clamp base and a wire clamp pressing cover which are fixedly arranged through bolts, and a wire placing groove is formed on a joint face of the wire clamp base and the wire clamp pressing cover. A damping rubber sleeve disposed on the inner wall of each wire placing groove in attaching mode is divided into two damping rubber pads with the joint face as an interface, and the two damping rubber pads are respectively attached to the wire clamp base and the wire clamp pressing cover. By aid of the technical scheme that the two damping rubber pads are matched to form one damping rubber sleeve, the spacing stick can be used to clamp a wire to enable the wire to form a flexible holding structure, meanwhile, the clamping effect of the wire clamps is more stable and reliable, fatigue damage of torsion to the rubber sleeve is relieved, and overall service life of the spacing stick is further prolonged.

Description

The single conductor composite alternate interval rod

Technical field

The utility model relates to a kind of built on stilts connection gold utensil of cable, relates in particular to a kind of single conductor composite alternate interval rod that keeps the wire phase spacing, suppresses conductor galloping.

Background technology

Vertical institute is known, conductor spacer is to reach the instrument that keeps the geometry of bundle conductor under normal operation for the relative motion between the restriction wire, and in actual the use, because difference and the different of weather conditions of each circuit mounting means will cause alternate wire to do different motions, so that the stressed more complicated of whole device and inhomogeneous, contact performance is not good, especially the rubber sleeve of integral type in the prior art, when the circuit relative motion, produce easily moment of torsion, and then the fatigue rupture that produces stress, affected greatly stability in use and the useful life of conductor spacer.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provide a kind of solid and reliable, contact good, the single conductor composite alternate interval rod of long service life.

For achieving the above object, the utility model adopts a kind of single guiding composite alternate interval rod, comprise plug and the ear line of rabbet joint folder that is arranged on the plug two ends, radially extend on the described plug perisporium and be provided with large full skirt and little full skirt, and described large full skirt and little full skirt distribute in the staggered mode in space, described ear line of rabbet joint folder comprises wire clamp base and the wire clamp gland that is bolted installation, and the composition surface at wire clamp base and wire clamp gland forms trunking, fit on the described trunking inwall and be provided with the damping rubber cover, it is that interface forms two damping rubber pads that are fitted in respectively on described wire clamp base and the wire clamp gland that described damping rubber is embedded with described composition surface.

By the technique scheme improvements over the prior art, owing to adopted two damping rubber pads to cooperate the technical scheme that forms the damping rubber cover, so that conductor spacer is carrying out when clamping wire makes it to form flexible clasping structure, the clamping effect of wire clamp is also more solid and reliable, and extenuated moment of torsion that integral type damping rubber cover in use produces to the fatigue damage of itself, and and then prolonged the whole service life of conductor spacer.

Preferably, for so that damping rubber pad and cooperating of trunking are more compact reliable, described damping rubber pad extends radially outwardly in the position, edge, two ends of described trunking and is provided with the clamping flange.

Preferably, described ear line of rabbet joint folder is upper is provided with the anti-back pin on the screw rod of hard-wired bolt.
