Meanwhile, when the wire is fixed by the wire hanging hardware fitting 2, the wire hanging hardware fitting 2 is fixedly arranged at the end part of a core rod 6 of the composite insulating cross arm through a crimping groove 21, after the composite insulating cross arm is arranged on a telegraph pole, a constructor only needs to carry one composite insulating cross arm for the first time to climb upwards and install, the subsequent composite insulating cross arm can be directly lifted upwards through a pulley by a worker at the lower end, wherein a paying-off pulley sliding suspension ring is used for field installation, a paying-off pulley is buckled on a paying-off pulley suspension ring 25, the composite insulating cross arm is lifted to a preset position through the pulley and a rope, a wire hanging end 24 is used for binding the wire, the bottom of an arc groove 23 on the wire hanging end 24 is lower than the upper end surface of the crimping groove 21, the width of the arc groove 23 is suitable for all wires in a 10kV overhead line, meanwhile, the operation space for installing the wire is enlarged, and the arc groove 23 with a certain depth can effectively avoid the risk of left-right force slippage of the wire, the whole wire hanging hardware fitting 2 is reduced in size, small in occupied space and beneficial to storage and packaging of products, the strength of the wire hanging hardware fitting 2 is guaranteed, the overall weight is reduced, and compared with the existing product, the weight can be reduced by about 40%; the installation is easier, so that the site construction and transportation are more convenient; the region for placing the wire on the wire hanging end 24 adopts an arc-shaped groove 23 structure with an upward opening, so that the wire can be stably sunk into the arc-shaped groove 23 after being placed, the limiting of the wire is more convenient, the falling phenomenon of the wire is avoided, the bonding surface area of the wire and the groove is larger, the stress abrasion of the wire is effectively protected, and the service life is prolonged; the position that the wire was placed is close the cross arm central line, has reduced because the wire bears the pulling force between increase gold utensil and the cross arm such as side wind load, wire galloping, simple structure, and the construction operation is convenient, the security is high, the quality is light, occupation space is little, the ligature is convenient, the dependable performance.
The improved structure is characterized in that the connecting seat 11 is of a U-shaped structure, two sides of the connecting seat 11 are respectively provided with the U-shaped clamping grooves 7 with the openings facing outwards, two sides of the connecting seat 11 are fixedly attached to two sides of the rectangular seamless steel tube 9, and a dismounting gap 8 is formed between the bottom of the connecting seat 11 and the rectangular seamless steel tube 9.
The connecting seat 11 adopts a U-shaped structure, and two side edges are fixed on two sides of the rectangular seamless steel tube 9, so that the width of the whole fixing hardware fitting 1 is thinner and the firmness is better after the connecting seat 11 is fixed, meanwhile, the disassembly and assembly gap 8 can be naturally formed after the fixing, the structure is simpler, the manufacturing cost is lower, particularly, the binding surface between the connecting seat 11 and the rectangular seamless steel tube 9 is welded and fixed, the fixing firmness is higher, and the construction is more convenient, and connecting seat 11 adopts the thick metal sheet that is 2 ~ 4mm of board, can make its life longer and weight lighter, and the security is higher, and whole fixed gold utensil 1's quality is lighter, occupation space is littleer, the performance is more reliable, and the effectual field installation that has solved original gold utensil and has brought transports difficulty, troublesome scheduling problem of construction to further improve the economic nature of product, construction operation's convenience and security.
Because the both sides of connecting seat 11 respectively are equipped with at least one U type draw-in groove 7 that the opening is outwards, two U type draw-in grooves 7 are respectively to both sides opening, when effectively reducing bolt quantity, still can guarantee that compound insulation cross arm is erecting installation wire and is accomplishing the back, can not cause fixing bolt's pine to take off because of factors such as the wire bears the side wind load, the wire waves, the construction is more convenient, compare with original product quality heavily, has alleviateed about 20%, the site operation of being convenient for transports.
The improved structure is characterized in that the connecting seat 11 comprises a first buckling plate 10 and a second buckling plate 12, and the first buckling plate 10 and the second buckling plate 12 are respectively provided with the U-shaped clamping groove 7 with an outward opening.
The connecting seat 11 comprises first buckle 10 and second buckle 12, can make the fixed weight that reduces whole connecting seat 11 when more nimble U type draw-in groove 7 relative position interval of both sides makes whole fixed gold utensil 1 weight lighter.
The further improvement is that the downward bulge of the line releasing pulley hanging ring 25 is arranged at the bottom of the line hanging end 24, and the arc-shaped groove 23 is of a U-shaped groove structure.
When carrying out the ligature to the wire through the ligature rope, unwrapping wire pulley link 25 is protruding structure downwards in 24 bottoms of string wire ends, can make behind the ligature rope ligature of ligature more firm, and also more convenient during the ligature, especially arc recess 23 is U type groove structure, can make the wire be absorbed in arc recess 23 completely, and the bigger U type recess of the degree of depth can effectively avoid the risk of atress slippage about the wire more.
In a further improvement, the wire contact surface 22 on the arc-shaped groove 23 is in an arc-shaped convex structure.
Because the wire presents both sides nature flagging phenomenon after placing arc recess 23, therefore, wire contact surface 22 on the arc recess 23 is the protruding structure of arc, wire contact surface 22 of hanging wire end 24 designs large tracts of land arc laminating according to the flagging angle of wire, wire contact surface 22's radian size is relevant with the weight of wire and the wire length between two adjacent wire contact surfaces 22, the radian when the wire downwarping is big more, wire contact surface 22's protruding radian is higher, the effectual orthogonal friction that has reduced the wire between the gold utensil, the contact surface has been increased, the life of wire has been strengthened, the effectual cracked phenomenon of side cut that has avoided wire contact surface 22 and wire to appear in fixed process.
The improved structure is characterized in that a binding threading opening 27 is formed in the paying-off pulley hanging ring 25, and a binding belt used for binding a lead passes through the binding threading opening 27 and reaches the bottom surface of the hanging wire end 24 to bind the lead in a winding manner.
