Operating characteristic by conductor spacer can be divided into two classes substantially, i.e. damp type conductor spacer and non-damp type conductor spacer.Damp type conductor spacer characteristics are: utilize rubber to consume the vibrational energy of lead as damping material in conductor spacer turning joint place, conductor vibration is produced damping action.
Existing damp type conductor spacer is generally respectively reserved four or eight installing holes that can block rubber column on chassis body and clamper main body, these rubber columns constitute damping system, this damping system consumes the vibrational energy of lead, and conductor vibration is produced damping action.Yet there is following shortcoming in the damp type conductor spacer of this installation rubber column: the one, rubber column is installed trouble, the position that needs constantly to adjust rubber column could guarantee all rubber columns are in place, to installer's requirement than higher; The 2nd, in the long-distance transportation of high-altitude, need the low weight damp type conductor spacer of quality, yet the damp type conductor spacer of this structure is heavier, is unsuitable for the high-altitude long-distance transportation.
Summary of the invention
Purpose of the present invention is to provide a kind of conductor spacer with single damping rubber.
The solution that the present invention solves its technical problem is: a kind of conductor spacer with single damping rubber, it comprises chassis body and is hinged on a plurality of wire clamp main bodys on the chassis body, be hinged with the wire clamp gland on the described wire clamp main body, the hinged place of described chassis body and wire clamp main body is provided with through hole, the installation end of described wire clamp main body is provided with the shape wire clamp through hole consistent with through hole, be with a rubber sleeve in described through hole and the wire clamp through hole, described chassis body and wire clamp main body install and fix behind the piece hinged by interference in the rubber sleeve.
As further improvement in the technical proposal, the cross section of described through hole and wire clamp through hole is ellipse, and the cross section of described rubber sleeve is elliptoid annular, and the cross section of described fixed block is oval.
As further improvement in the technical proposal, the hinged place of described wire clamp main body and chassis body is provided with two fixture blocks, form a screens between the described fixture block, described screens is stuck in after the chassis body by the interference of rubber sleeve and fixed block hinged with wire clamp main body and chassis body is installed.
As further improvement in the technical proposal, described chassis body and the hinged place be provided with two fixture blocks, form a screens between the described fixture block, described screens is stuck in after the wire clamp main body by the interference of rubber sleeve and fixed block hinged with wire clamp main body and chassis body is installed.
As further improvement in the technical proposal, pipe box is installed also between described fixed block and the rubber sleeve.
As further improvement in the technical proposal, an end of described rubber sleeve is provided with boss, and the external diameter of described boss is greater than the internal diameter of wire clamp through hole.
As further improvement in the technical proposal, the quantity of described wire clamp main body is a kind of in 2,3,4,6 and 8.
The invention has the beneficial effects as follows: it is hinged that the present invention installs and fixes behind the piece implementation framework main body and wire clamp main body by interference in the rubber sleeve between chassis body and the wire clamp main body, form damping system between rubber sleeve, fixed block, chassis body and the wire clamp main body, utilize damping system to consume the vibrational energy of lead, conductor vibration is produced damping action, this simple in structure, easy for installation, be applicable to the high-altitude long-distance transportation.
Description of drawings
