Description

Tripartition damping spacer

Technical field

The utility model relates to a kind of tripartition damping spacer, belongs to conductor spacer field of structural design.

Background technology

Transmission line distribution wires; tripartition wire triangularity shape designs; generally in energising situation, can produce very strong attraction with phase conductor made for two wires moments mutually draw close; even produce whiplash situation; and when daily circuit runs; because naturally large wind action also can make wire collision friction, so often can use cracking separation rod in actual track is installed.Just product adopted in the market is generally version is equilateral triangle, wire centripetal force when being energized instantaneously increases suddenly, belong to rigidity between the product clamp arm of equilateral triangle structure and center bearing bracket to collide, damping is not obvious, no matter is all can produce certain infringement to wire or to product itself.Overhead transmission line is in wind swinging condition for a long time at high dry running, does irregular waving for a long time, and product and wiring system do the phenomenon that rigid collision there will be wire fracture or damage of product unavoidably for a long time.

Embodiment

Do to illustrate below in conjunction with the concrete structure of Figure of description to tripartition damping spacer of the present utility model:

A kind of tripartition damping spacer, the wire clamp 3 as shown in Figures 1 to 4, comprising center bearing bracket 1 triangular in shape, be located at the connection bracket 2 on the described each summit of center bearing bracket 1 and be fixed in described connection bracket 2, described wire clamp 3 comprises wire clip body 31 and coordinates the wire clamp gland 32 of clamping wires with described wire clip body 31, described connection bracket 2 is connected by riveted pipe 4 and the damping mat 5 be socketed on described riveted pipe 4 with described wire clip body 31 with described center bearing bracket 1 and described connection bracket 2, described center bearing bracket 1 and described wire clip body 31 are provided with the location hole with corresponding damping mat 5 location fit, on the cross sectional shape of described riveted pipe 4 and described damping mat 5, the cross sectional shape of trepanning 51 matches, when there is opposing oscillatory to make described wire clamp 3 with described center bearing bracket 1, damping torque can be produced between described damping mat 5 and described riveted pipe 4.In the present embodiment, by between center bearing bracket 1 and connection bracket 2, and damping mat 5 is set between connection bracket 2 and wire clip body 31 can realizes Quadratic Damping, thus wire has good damping when swinging, avoid rigid collision, there is good result of use.

Described connection bracket 2 in the present embodiment connects and composes " Z " character form structure with described wire clamp 3, adopts this structure, when conductor spacer is subject to centripetal power, has better damping, avoid contingent rigid collision.

In the present embodiment, described riveted pipe 4 is the ellipse or polygon that match with the cross sectional shape of described trepanning 51.

Further, it is hinged that bearing pin 6 is passed through in one end of described wire clamp gland 32 and one end of described wire clip body 31, the other end of described wire clamp gland 32 is connected by clamping screw 7 with the other end of described wire clip body 31, the roller pin 8 that can rotate around own axes is provided with in the perforation of described wire clip body 31, described bolt is threaded with the screw in described roller pin 8, and together can rotate with described clamping screw 7, described clamping screw 7 is tightened and described wire clamp gland 32 can be locked after screwing in gland fluting 33, easily described wire clamp gland 32 can be locked with wire clip body 31 by adopting this structure, without the need to clamping screw 7 and wire clamp gland 32 are pulled down from wire clip body 31 in disassembly process, so that work high above the ground.

Further again, described roller pin 8 is stepped cylindrical shape type, described perforation is the ladder-type structure matched with described roller pin 8, by adopting this structure, roller pin 8 and perforation grafting coordinates put in place after can to slot spacing for described clamping screw 7 33 corresponding position activities with described wire clamp gland 32 upper press cover, thus clamping screw 7 can be entered in gland fluting 33 more smoothly, be conducive to locking operation.

Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection range of the present utility model.
