In summary, be different from the condition of prior art, flange in this application is through setting up the quotation of first ring flange and the outer peripheral face fixed connection of first flange section of thick bamboo, when using crossbeam and support piece in the flange connection transformer framework, only need with the quotation fixed connection of second ring flange in quotation of first ring flange and the support piece, thereby on the one hand can reduce the number of component in the transformer framework, practice thrift raw and other materials, reduce the overall weight of transformer framework, convenient transportation and reduce cost, on the other hand contact area between first ring flange and the second ring flange is big, can guarantee the joint strength between crossbeam and the support piece, avoid crossbeam and support piece separation, eliminate the potential safety hazard.
Meanwhile, the thickness of the first flange plate in the flange is uniformly increased from one side far away from the first flange cylinder to one side close to the first flange cylinder in the axial direction, so that the cross beam can be lifted upwards when the two flanges are used for enabling the cross beam to be erected and fixed on two supporting pieces, the cross beam is enabled to be an arched cross beam arched in the direction far away from the ground, and therefore when a wire is hung, the cross beam can offset a part of vertical sag by utilizing the arched height of the cross beam, and potential safety hazards are further eliminated.
Further, the flange in the application still includes a plurality of strengthening ribs, can strengthen the joint strength of flange through a plurality of strengthening ribs rationally distribute.
The foregoing description is only of embodiments of the present application, and is not intended to limit the scope of the patent application, and all equivalent structures or equivalent processes using the descriptions and the contents of the present application or other related technical fields are included in the scope of the patent application.
