Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, a kind of steel pipe pole steel pipe cross-arm of eight rib variable cross-sections is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of steel pipe pole steel pipe cross-arm of eight rib variable cross-sections, its composition comprises: cross-arm main body, conducting wire hanging point device, adpting flange, the cross section of described cross-arm main body is octagon, described cross-arm main body cross section is along its length trapezoidal, described cross-arm body front end is provided with the conducting wire hanging point device of level, described cross-arm body rear is fixedly connected with adpting flange, on described cross-arm, be provided with aisle.
Further, described cross-arm main body welds aisle connecting angle, the elevation angle a of described cross-arm main body is 4 °.
Further, described aisle comprises two angle steel one, round steel, handrails, and two described angle steel are parallel in the horizontal direction, and described round steel is welded between two angle steel one, and the outside of described angle steel one is welded with handrail.
Further, described conducting wire hanging point device is made up of two angle steel two, and described angle steel two has the hole that 3 spacing are identical.
Further, described cross-arm main body is connected with steel pipe pole by adpting flange, and described adpting flange is square steel plate, and the surrounding on described adpting flange is provided with 24 through holes.
Further, described aisle connecting angle and described angle steel one are bolted.
The invention has the beneficial effects as follows:
1. the present invention is the novel steel tube cross-arm of variable cross-section eight rib type, and cross-arm main body adopts eight rib variable-section steel pipes, and only a longitudinal joint along steel pipe length direction needs welding, greatly reduces labor content.
2. cross-arm and the body of rod adopt Flange joint, more solid and reliable than inserting mode in the past.
3. cross-arm faces upward 4 °, avoid cross-arm sagging time, the Action of Gravity Field due to circuit causes the phenomenon of whole body of rod run-off the straight.

Detailed description of the invention:
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
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 °, the number of degrees of this elevation angle a, 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.
Angle steel 1 lower limb face processing connecting hole and cross-arm on connecting angle 6 bolt.
Its making and installation process is: according to concentric reducer size and the length of eight rib variable-section steel pipe cross-arms, according to eight rib variable cross-section cross-arm cross section development sizes, by the Q345B steel plate cutting that 6mm is thick, concentric reducer steel plate divides equally 8 parts respectively, bender carries out bending, be converted into the steel pipe of octagon, the eight prismatic steel pipes that doubling is made carry out the welding of joint close and longitudinal joint, make cross-arm main body; Then be welded to connect flange in the rear end of cross-arm, weld the angle steel two of two in the front end of cross-arm; Cross-arm body welds aisle connecting angle, and the connecting angle on the aisle of Armrest and cross-arm is bolted fixing, welds complete cross-arm and is connected with body of rod flange by bolt, complete the assembling of cross-arm and the body of rod.
