Description
Technical field
The utility model relates to and a kind of cross-arm is fixed on gold utensil on the power transmission and distribution shaft tower, especially relates to a kind of power transmission and distribution composite material cross-arm frock gold utensil.
Background technology
Cross-arm is the important link that connects power transmission and distribution shaft tower and lead, because problems appear in traditional cross-arm in actual applications, the composite material cross-arm that therefore has big application advantage arises at the historic moment.The composite material cross-arm is as the novel cross-arm product of a class, have excellent insulation performance, designability can be good, corrosion-resistant etc. application characteristic, therefore at its security of operation that can greatly ensure transmission line of electricity in service, reduce operation expense.Because the composite material cross-arm is different from traditional cross-arm in application characteristic, and its form of structure is tubulose or club shaped structure according to present preparation technology, especially the composite material cross-arm need have special-purpose frock gold utensil installing of cross-arm with conventional angular head tower fit applications the time.Mostly traditional composite material cross-arm is that with continuous glass fiber be reinforcing material, thermosetting resin is that matrix is prepared from, adopting punching to add the bolt mode in frock links to each other with power transmission and distribution shaft tower bar (tower) body, this kind method easily produces stress and concentrates around hole wall, and then in the cross-arm hanging net operation, cause cracking during bearing load, influence the circuit security of operation.Therefore, how effectively to utilize the characteristics of composite material cross-arm, the composite material frock gold utensil of effective connection conventional angular head tower reasonable in design becomes the problem that needs solution.
The utility model content
Technical problem to be solved in the utility model, 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, influence the problem of circuit security of operation.
Solve the problems of the technologies described above, the technical scheme that the utility model adopts 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 made up of preceding anchor ear 21, back anchor ear 22 and connector 4, and involutory anchor ear 2 with composite material cross-arm 1 banding, has screw hole 311 on the back anchor ear 22 by connector 4; Also has built-up jig 3, it also has nut by first screw rod 31, second screw rod 32, first clamper 33, second clamper 35 and nut 34(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; First screw rod 31 passes the connection sleeve joint hole 321 on connecting screw rod hole 311, second screw rod 32, the symmetrical holes of first clamper 33 on the anchor ear 22 of back successively; The symmetrical holes that second clamper (35) are passed in 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 nut 34 at last 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 the 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 of forming 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 utility model is by involutory anchor ear and the common frock gold utensil of forming of built-up jig, the composite material cross-arm effectively is 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 the composite material cross-arm and concentrated because punching produces stress, improved the circuit security of operation.
