Abstract
The utility model relates to a strain wire clamp used for a 10kV overhead power distribution line. The strain wire clamp used for the 10kV overhead power distribution line includes a wire clamp body used for allowing a carbon fiber beam to penetrate through, an outer sleeve sleeved outside the wire clamp body and a U-shaped pull rod. A conical central through hole is arranged in the outer sleeve axially. The inner wall of the tail end of the outer sleeve is provided with female threads and the outer wall of the tail end of the outer sleeve is provided with male threads. The outer sleeve is in female connection with a locking block used for pushing against the wire clamp body while is in male connection with a pulling force bearing board. The U-shaped pull rod is connected to the pull force bearing board. Two ends of the wire clamp body are provided with two notches in a staggered manner and the inner surface of the wire clamp body is provided with anti-slide threads. By adopting the strain wire clamp used for the 10kV overhead power distribution line, installation can be facilitated, labor strength of operators is reduced and working efficiency is improved. And the strain wire clamp used for the 10kV overhead power distribution line is long in service lifetime.
Description
Technical field
The utility model relates to the field of power industry, especially a kind of 10 kilovolts of overhead distribution strain resistant wire clamps.
Background technology
At present, set up at transmission line the strain clamp used in operation, the three types strain clamp is arranged: a kind of is compression type, wire clamp is aluminium alloy aluminum pipe processed, during installation, wire is inserted at two ends, then with hydraulic tool, it is compressed, wire is linked together, and this product uses inconvenience, and need to carry heavy hydraulic tool, operating speed is slow, aluminum pipe bears up to a hundred tons of pressure, and flow of metal own is very large, and the metal metallographic is changed in various degree, crackle appears in the wire clamp body, causes mechanical strength to reduce and easily meets accident; The second is sudden and violent pressure type, and wire clamp is also aluminium-alloy pipe, and after the wire Inserting Tube is interior, outside is wrapped with explosive rope, and the powerful impulsive force by the moment of detonating, make wire clamp clamp wire, but, due to powerful impulsive force, the metal metallographic is changed in various degree, and mechanical strength reduces; The third is bolt type strain clamp, by bolt clip tensile force wire, owing to being subject to wind-force, freeze or other vibrations cause loosened screw, cause wire to slide in wire clamp, conducting wire sag descends, easily causes the race line, and its above-mentioned wire clamp exists installs the shortcomings such as inconvenient, that effect is bad.
For above-mentioned phenomenon, a kind of wedge-shaped insulation strain clamp has appearred in the market, due to after the pellet used in this kind of wire clamp holds cable, then by the relative sliding of lozenges between wiring clip shell and pellet, pellet is held with a firm grip cable, because the pellet used at present and the sliding friction of wire fix wire, due under rain drop erosion, easily cause skidding, cause two pellets inconsistent phenomenon to occur, thereby can't produce a desired effect.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of 10 kilovolts of overhead distribution strain resistant wire clamps, its project organization rationally, can realize avoiding pellet inconsistent phenomenon and easy for installation.
The utility model solves the technical scheme that its technical problem adopts: a kind of 10 kilovolts of overhead distribution strain resistant wire clamps, comprise the wire clip body for placing carbon fiber bundle and be nested with outer sleeve and the U-shaped pull bar in the wire clamp body exterior, axially offer conical centre's through hole in described outer sleeve, offer on internal thread and outer wall and offer external screw thread on the tail end inwall of outer sleeve, described outer sleeve is connected with for withstanding the clamping block of wire clip body by internal thread, outer sleeve is connected with and bears plate by external screw thread, U-shaped pull bar is connected to and bears on plate, the twice notch is offered respectively in the mode that staggers in described wire clip body two ends, offer antiskid thread on the wire clip body inner surface.
The U-shaped place of described U-shaped pull bar is coated with wear-resistant pad.
The taper value of the conical centre's through hole in described outer sleeve is 3 °.
The beneficial effects of the utility model are: described a kind of 10 kilovolts of overhead distribution strain resistant wire clamps, adopt the wire clamp of this kind of design, and can be quick and easy for installation, alleviated operating personnel's labour intensity, high efficiency, and long service life.
