Abstract
This technology discloses a kind of four line angles iron cross arm, including four line angle iron cross arm bodies, and the four line angles iron cross arm body includes 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.In the use of the present invention, being contacted by two triangle iron plates being symmetrically distributed on transverse slat with electric pole, the present invention is set more to consolidate；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 present invention is stably mounted on electric pole.
Description
Technical field
This technology is related to a kind of install is used for the cross-arm of supporting electric wire on utility poles, more particularly to a kind of four line angles iron is horizontal
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, be no longer an angle iron above, but a brandreth laterally set up, it is built on stilts for supporting
Electric wire, present someone is also this crossbearer cross-arm, also angulation iron cross arm.Cross-arm is important part in shaft tower, it
Effect is, for installing insulator and gold utensil, to support wire, lightning conducter, and to be 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 is using single cross-arm, and angle pole, tension-resistant rod, terminal pole, branch bar of the corner more than 15 degree all use double cross-arms.Angle bar
When in use, its general middle part can be contacted cross-arm with electric pole, because general tensed angle bar cross-arm in electricity by fixing device
In line bar, i.e., angle bar cross-arm is that point is contacted with electric pole.With increasing for being born a heavy burden on angle bar cross-arm, along with the influence of wind-force,
Angle bar cross-arm is rocked 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 a kind of four line angles iron cross arm of offer, 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 includes 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, send out this
It is bright more to consolidate；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 main structure diagram of the invention.
Fig. 2 is overlooking the structure diagram of the invention.
The embodiment to this technology is described further below in conjunction with the accompanying drawings.
