Preferably, described ring-type platform circle is provided with for making pickle and the smooth and easy auxiliary hole flow through of galvanizing flux, and described auxiliary hole is positioned at the one or both sides connecting monaural.
Preferably, two opposite side of the cross-sectional plane of described false boss are that the class of circular arc, other two opposite side symmetrically pattern draft is oval.
On the other hand, the utility model also provides a kind of oblique wrist and arm being provided with above-mentioned bracket monaural.
The following technical scheme of concrete employing:
A kind of oblique wrist and arm of electrification railway contact net, it bracket monaural comprising bracket pipe and be fixedly installed on bracket tube end, described bracket monaural comprises ring-type platform circle, false boss and connects monaural, described connection monaural is vertically fixedly installed on ring-type platform circle side, described false boss is two or more and is fixedly installed on ring-type platform circle opposite side, arrange a connecting bore in the middle part of described connection monaural, described ring-type platform circle is provided with the groove for welding with bracket pipe at the periphery of the side being provided with false boss.
Preferably, described ring-type platform circle is provided with communicate with bracket pipe for making pickle and the smooth and easy auxiliary hole flow through of galvanizing flux, described auxiliary hole is positioned at the one or both sides of connection monaural.
Preferably, described shutoff plug is plastic plug or aluminum pulling rivet.
Preferably, two opposite side of the cross-sectional plane of described false boss are that the class of circular arc, other two opposite side symmetrically pattern draft is oval.
Good effect of the present utility model is as follows:
The utility model has that structure is simple, manufacture craft is simple, lightweight advantage.Bracket monaural just forges in ring-type platform rounded edge the groove be convenient to when welding when forging, facilitate welding of bracket pipe and bracket monaural, eliminate machined into operation, simplify manufacturing process, in addition, the class in the false boss cross section of bracket monaural afterbody being symmetrical circular arc and symmetrical pattern draft composition is oval, do not need machined into just directly can fill in bracket pipe inner, and relatively traditional cylinder, both eliminated machined into operation, again save material, alleviate weight.Its ring-type platform circle arranges auxiliary hole, pickle and galvanizing flux can be facilitated to flow through whole oblique wrist and arm, improve the quality of zincincation.
The oblique wrist and arm of electrification railway contact net disclosed in the utility model, because its bracket monaural has, structure is simple, manufacture craft is simple, lightweight advantage, whole oblique wrist and arm is provided with simultaneously making is more convenient, quality is more stable, weight is lighter advantage.
