Detailed description of the invention:
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of steel pipe pole steel pipe cross-arm of eight rib variable cross-sections, its composition comprises: cross-arm main body 2, conducting wire hanging point device 5, adpting flange 1, the cross section of cross-arm main body 2 is octagon, this octagon is positive octagon, cross-arm main body 2 cross section is along its length trapezoidal, namely the distance of cross-arm front end octagon opposite side is less than the distance of cross-arm rear end octagon opposite side, when ensureing structural strength, cross-arm front end can be lighter, when hanging wire, well can ensure that cross-arm can not be sagging, the steel plate thickness of cross-arm main body 2 is 6mm, material is Q345B, cross-arm main body 2 front end arranges the conducting wire hanging point device 5 of level, cross-arm main body 2 rear end is fixedly connected with adpting flange 1, aisle 3 is provided with on cross-arm main body 2.
Cross-arm main body 2 is welded aisle connecting angle 6, the elevation angle a of cross-arm main body is 3 ° ~ 8 °, this elevation angle a the number of degrees, can according to the downward pulling force of the distance of steel pipe pole and hanging wire, carrying out adjustment to arrange, making cross-arm not sagging when being subject to the different pulling force of hanging wire.
Aisle 3 comprises two angle steel 1, round steel 7, handrail 4, and the outside of angle steel 1 is welded with handrail 4, ensures the safety of constructor on aisle during operation.
Conducting wire hanging point device 5 is made up of two angle steel 29, distance between angle steel two can need to arrange according to practice of construction, simultaneously, in conducting wire hanging point device, the quantity of angle steel two also can carry out increasing or reducing in actual application, and two is the most frequently used quantity, 3 holes 10 being processed by angle steel 29, as hanging wire insulation substring, can go here and there with two by sheet string simultaneously.
Cross-arm main body 2 is connected with steel pipe pole by adpting flange 1, and the Q345 square steel plate that adpting flange 1 is, flange surrounding arranges the through hole 11 of 24, is used as to be connected with the adpting flange on the steel pipe body of rod.
