Description
Technical field
The present invention relates to strain clamp, specifically a kind of carbon fiber strain clamp.
Background technique
Strain clamp is the fitting for fixing conducting wire in overhead transmission line, for concatenating conducting wire and insulator, thus exhausted
After edge is connected with steel tower, effectively carries the pulling force of conducting wire, reduces the sag of conducting wire.Currently, with carbon fiber composite conductor
Be widely used, how effectively, stable connection carbon-fibre wire becomes those skilled in the art's technology urgently to be resolved and asks
Topic.Existing strain clamp common problem is, carbon fiber plug and outer layer aluminium development length is inconsistent causes when stress
Wire tension can not maximize performance.
Summary of the invention
To solve the above problems, the present invention provides a kind of carbon fiber strain clamp, and securely and reliably, using flexible, installation side
Just quick.
The technical solution adopted by the present invention is that：A kind of carbon fiber strain clamp, including steel anchor, steel anchor sleeve, slide bar, aluminium lining
Pipe, steel pipe and aluminum pipe, the steel anchor is by link and there is externally threaded solid part to form, and the slide bar is hollow bushing, outside
Wall is divided into thread segment and non-threaded section, and the internal screw thread that one end of the steel anchor sleeve is arranged by its inner sidewall is solid with steel anchor
Portion's connection, the other end are set in non-threaded section of outside of slide bar, the internal screw thread that one end of the steel pipe is arranged by its inner sidewall
It is connect with the thread segment of slide bar, the other end is set on the outside of aluminium bushing pipe, and the aluminum pipe is set in the outside of steel anchor sleeve and steel pipe
And the length of aluminum pipe is greater than the total length of steel anchor sleeve and steel pipe.
The steel anchor sleeve is equipped with multiple annular grooves close to one end outer surface of steel anchor link.
Non-threaded section of the slide bar is equipped with O shape bumper ring between steel anchor sleeve.
The steel pipe uses taper structure.
The aluminium bushing pipe uses graphene alumina-base material.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
As shown in Figures 1 to 5, a kind of carbon fiber strain clamp, including steel anchor 1, steel anchor sleeve 2, slide bar 3, aluminium bushing pipe 4,
Steel pipe 5 and aluminum pipe 6, steel anchor 1 is by link 11 and there is externally threaded solid part 12 to form, and slide bar 3 is hollow bushing, outer wall point
For thread segment 31 and non-threaded section 32, slide bar pre-stretched scale can be produced according to different requirements, assembling solidification when factory
It is good, in actual use without adjustment, need to only be operated according to conventional strain insulator, it is securely and reliably, convenient and efficient.Steel anchor sleeve
The internal screw thread that 2 one end is arranged by its inner sidewall is connect with the solid part 12 of steel anchor, and the other end is set in the non-threaded of slide bar 3
32 outside of section, steel anchor sleeve 2 are equipped with multiple annular grooves 21 close to one end outer surface of steel anchor link.One end of steel pipe 5 passes through it
The internal screw thread of inner sidewall setting is connect with the thread segment 31 of slide bar 3, and the other end is set in 4 outside of aluminium bushing pipe, and aluminum pipe 6 is set in steel
The length of the outside of anchor sleeve 2 and steel pipe 5 and aluminum pipe is greater than the total length of steel anchor sleeve and steel pipe.It is seperated by steel anchor and slide bar
Structure design, carbon fiber plug and outer layer aluminium are individually crimped, and are separated stress, are made up carbon fiber plug by the pre-stretched of slide bar
With the extension difference between outer layer aluminium, carbon fiber plug and outer layer aluminium development length is inconsistent leads to conducting wire when can effectively solve stress
Tension can not maximize the problem of performance.
Non-threaded section 32 of slide bar 3 is equipped with O shape bumper ring 7 between steel anchor sleeve 2, and what is generated when load being avoided to be mutated rushes
It hits and product structure and conducting wire carbon fiber plug is damaged；.
The steel pipe 5 for crimping carbon fiber plug uses taper structure.It realizes that plug pressure is stepped down to zero, effectively changes
Kind carbon fiber plug by pressure condition, avoid carbon fiber plug impaired and generate stress concentration point in exit.
Novel graphene alumina-base material is used with the aluminium bushing pipe 4 that carbon fiber plug directly contacts.The material yield strength and
Tensile strength is more preferable, while material ductility is improved, and when crimping can preferably extend and hold and protect carbon fiber plug,
Ensure that carbon fiber plug will not be damaged because of directly contacting with steel pipe with high hardness, its performance is enable to fully play.
Prefilled conduction grease, the automatic-extrusion in sliding bar fill the cavity of generation in steel anchor sleeve 2, can be effective
Prevent the intrusion of rainwater.
This carbon fiber strain clamp not only can be adapted for being crimped using crimping equipment（As UC140 sweet smell treasured is withheld
Machine）, it is also applied for common hydraulic press and carries out live crimping（Such as SY-BJC-1250/80 type hydraulic machine）, using flexible conveniently can
It leans on.
