Load is part important in shaft tower, its effect be for installing insulator and gold utensil, to support wire, lightning conducter, and
It is allowed to keep certain safe distance by regulation.It can be divided into by purposes：Straight line cross-arm；Buck arm；Strain cross arm.Can by material
It is divided into：Iron cross arm；Porcelain pole arm；Composite insulation cross-arm.
Straight line cross-arm：Only consider in the case of not breaking normally, bear the vertical load and horizontal loading of wire；Strain insulator is horizontal
Load：Wire is born vertically and horizontally outside loading, it is also that the pulling force for bearing wire is poor；Buck arm：Except bear the vertical of wire and
Outside horizontal loading, will also larger unilateral wire tension be born.According to the stressing conditions of cross-arm, to straight line pole or less than 15 turn
Angular pole uses single cross-arm, and angle pole of the corner more than 15 degree, tension-resistant rod, terminal pole, branch bar are all using double cross-arms.Cross-arm
It is typically mounted at away from the 300mm of bar top, straight line cross-arm should be mounted in power side, and angle pole, terminal pole, the cross-arm of branch bar should be mounted in
Bracing wire side.Existing transmission of electricity cross-arm mounting stability is not high at present, easily causes structural damage when producing vibration, causes to install
It is inconvenient.And existing cross-arm structure is more complicated.
The content of the invention
Part in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of transmission of electricity cross-arm, the cross-arm structure
Simply, compact, installation is reliable and stable, and can be shockproof.
To achieve the above object, the utility model adopts the following technical scheme that：One kind transmission of electricity cross-arm, including cross bar, montant,
Spring, adjusting means and anchor ear, the centre of the cross bar and the top of montant are connected by connector, and one end of the cross bar is leaned on
Under be fixed with connection sheet, connection sheet middle is provided with through hole, and the spring one end passes through through hole, and the other end connects with adjusting means
Connect, the adjusting means includes the overcoat of annular, adjusting rod, and overcoat one end is provided with the annulus that be connected with spring, the annulus and
Overcoat is rotatablely connected, and the overcoat other end is provided with screwed hole, and the tail end of adjusting rod is provided with the external screw thread coordinated with screwed hole, adjusting rod
Head is hinged with montant bottom, and the afterbody of foregoing adjusting rod is connected after passing through screwed hole by two nuts with overcoat, foregoing horizontal stroke
Bar is provided with wire clamp, and the first pulley and second pulley for facilitating electric wire to set up are provided with wire clamp, and the anchor ear is arranged on montant
Bottom, the anchor ear is interior to be provided with rubber ring.
In the above-mentioned technical solutions, the nut is stop nut.
In the above-mentioned technical solutions, rounding is provided with the through hole.
In the above-mentioned technical solutions, the wire clamp is fixedly connected with cross bar.
The beneficial effects of the utility model are：Its is simple in construction, compact, and cost is low, easy for installation, and spring can effectively be prevented
Shake, while by adjusting rotating jacket, the elastic of spring can be adjusted, that is, the pulling force size of spring is adjusted, according to actual use
Demand and different pulling force is set, wide adaptation range；By nut check overcoat and adjusting rod, prevent overcoat and adjusting rod by
To vibration when release；Rounding in through hole, reduces the end of spring and shear stress that through hole contacts, and ensure spring uses the longevity
Life.
