Summary of the invention
Technical problem to be solved by this invention, just provide a kind of power transmission and distribution composite material cross arm frock gold utensil, need not punching adds the bolt mode and links to each other with power transmission and distribution shaft tower bar (tower) body, cause cracking in the time of so can avoiding in the cross-arm hanging net operation bearing load fully, affect the problem of circuit security of operation.
Solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of power transmission and distribution composite material cross arm frock gold utensil is characterized in that: comprise involutory anchor ear 2, it is comprised of front anchor ear 21, rear anchor ear 22 and connector 4, and involutory anchor ear 2 with composite material cross arm 1 banding, has screw hole 311 on the rear anchor ear 22 by connector 4; Also has built-up jig 3, it also has nut by the first screw rod 31, the second screw rod 32, the first clamper 33, the second clamper 35 and nut 34(the second clamper 35 ends) form, clamper is a microscler landolsring, be located at breach on one jiao and can be used to catch on angle steel edge on the power transmission and distribution shaft tower, have symmetrical holes on the ring and pass for screw rod; The first screw rod 31 passes the connection sleeve joint hole 321 on connecting screw rod hole 311 on the rear anchor ear 22, the second screw rod 32, the symmetrical holes of the first clamper 33 successively; The symmetrical holes that the second clamper (35) are passed in the second screw rod (32) end, two clampers are 90 degree, and breach catches on two edges of the angle steel on the power transmission and distribution shaft tower, installs at last nut 34 additional and is connected on the power transmission and distribution shaft tower.
Cross section after described involutory anchor ear clamps is corresponding with the cross-arm cross section.
Described involutory anchor ear passes through the connector banding on composite material cross arm, inner wall surface thereof and composite material cross arm closely cooperate behind the anchor ear banding, the built-up jig of described cleat angle is fixed on the anchor ear by screw rod, supporting two built-up jigs on the anchor ear, be used for the cleat angle pylon, described involutory anchor ear and two common combination hardware fittings that form one group of cleat angle of anchor clamps are equipped with two groups of combination hardware fittings on the cross-arm.
Described composite material cross arm is a kind of in square or circular.
Beneficial effect: the present invention is by involutory anchor ear and the common frock gold utensil that forms of built-up jig, make composite material cross arm effectively be fixed on the angle steel tower, when having guaranteed effective connection of composite material cross arm and angle steel tower, not only simplified the frock mode of composite material cross arm, and reduced composite material cross arm and concentrated because punching produces stress, improved the circuit security of operation.
