Abstract
This technology discloses a kind of four line angle iron cross arms, including four line angle iron cross arm bodies, the four line angles iron cross arm body include transverse slat and riser；The mounting hole for installing porcelain kettle is provided with the riser；It is characterized in that：Two triangle iron plates are installed with the transverse slat；The triangle iron plate is symmetrically distributed on transverse slat.The length of the triangle iron plate is equal with the width of transverse slat.The utility model when in use, is contacted by two triangle iron plates being symmetrically distributed on transverse slat with electric pole, makes the utility model more firm；The length of the triangle iron plate is equal with the width of transverse slat, makes the contact surface of angle iron and electric pole more, further the utility model is stably mounted on electric pole.
Description
Technical field
This technology is related to a kind of cross-arm installed and be used for supporting electric wire on utility poles, more particularly to a kind of four line angle iron horizontal stroke
Load.
Background technology
In common line bar, the horizontal angle iron in line bar is cross-arm, for fixing porcelain kettle.Present extra high voltage network
Increase, line bar more frame is higher, is no longer an angle iron above, but a brandreth laterally set up, aerial for supporting
Electric wire, present someone is also this crossbearer cross-arm, also angulation iron cross arm.Cross-arm is part important in shaft tower, it
Effect is for installing insulator and gold utensil, to support wire, lightning conducter, and is allowed to keep certain safe distance by regulation.
Cross-arm can be divided into by purposes：Straight line cross-arm；Buck arm；Strain cross arm.It can be divided into by material：Iron cross arm；Porcelain pole arm；Synthesis is exhausted
Edge 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.Angle bar
When in use, its general middle part can contact cross-arm with electric pole, because typically being tensed angle bar cross-arm in electricity by fixing device
In line bar, i.e., angle bar cross-arm is that point contacts with electric pole.As that is born a heavy burden on angle bar cross-arm increases, along with the influence of wind-force,
Angle bar cross-arm rocks easily with respect to electric pole, and the length of time one can cause to loosen, and endanger transmission line safety.
The content of the invention
The purpose of this technology is to provide a kind of four line angle iron cross arms, and this four line angle iron cross arm passes through symmetrical two angle bar
Contacted with electric pole, it is more stable, durable.
To realize above-mentioned technical purpose, the technical scheme that this technology is taken is：A kind of four line angle iron cross arms, including four line angles
Iron cross arm body, the four line angles iron cross arm body include transverse slat and riser；The peace for installing porcelain kettle is provided with the riser
Fill hole；It is characterized in that：Two triangle iron plates are installed with the transverse slat；The triangle iron plate is symmetrically distributed in transverse slat
On.
As further improved technical scheme of the present invention, the length of the triangle iron plate is equal with the width of transverse slat.
In the use of the present invention, being contacted by two triangle iron plates being symmetrically distributed on transverse slat with electric pole, make this hair
It is bright more firm；The length of the triangle iron plate is equal with the width of transverse slat, makes the contact surface of angle iron and electric pole more, enters
One step makes the present invention be stably mounted on electric pole.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention.
Fig. 2 is the overlooking the structure diagram of the present invention.
The embodiment of this technology is described further below in conjunction with the accompanying drawings.
