For solving the problems of the technologies described above, the technical solution of the utility model is: multiloop is total to frame iron tower with tower, comprise the tower bar that connects and composes by the plurality of sections steel pipe, on described tower bar, be provided with the cross-arm assembly, described cross-arm assembly comprise one deck ground wire cross-arm of being located at described tower masthead portion and be located at described ground wire cross-arm below on, in, following three groups of lead cross-arms, described every group of lead cross-arm comprises the three layer conductor cross-arms that are arranged above and below and be arranged in parallel, and described one deck ground wire cross-arm and described every layer conductor cross-arm include two along continuous straight runs and be symmetrically set in cross-arm monomer on the described tower bar.
As a kind of optimized technical scheme, described ground wire cross-arm and the described cross-arm monomer of going up group lead cross-arm comprise that the cross section is hexagonal Taper Pipe, and the big caliber end of described Taper Pipe is connected with described tower bar by connecting plate, directly holds at the tubule of described Taper Pipe to be provided with thread gripping-board.
As a kind of optimized technical scheme, described in, the cross-arm monomer of organizing the lead cross-arm down is box-structure, the cross-arm monomer of described box-structure comprises top board, base plate and front and back side plate, is provided with thread gripping-board at described cross-arm monomer away from an end of tower bar.
As a kind of optimized technical scheme, the cross-arm monomer of described middle group lead cross-arm all is " sickleshaped ".
As a kind of optimized technical scheme, the upper strata cross-arm of three layer conductor cross-arms in described every group of lead cross-arm and lower floor's cross-arm are short, the intermediate layer cross-arm is long.
As a kind of optimized technical scheme, the plurality of sections steel pipe of described formation tower bar is the cross section and is circular or polygonal Taper Pipe.
After having adopted technique scheme, the beneficial effects of the utility model are:
1. because the utility model has adopted the three groups of lead cross-arms in upper, middle and lower, and every group of lead cross-arm comprises the three layer conductor cross-arms that are arranged above and below and be arranged in parallel, every layer conductor cross-arm includes two along continuous straight runs and is symmetrically set in cross-arm monomer on the tower bar.Therefore, the three groups of lead cross-arms in upper, middle and lower can set up 220kV double loop, 110kV double loop and 35kV double loop high-voltage line respectively, and then a shaft tower just can set up six loop high-voltage lines simultaneously.So the utility model not only realizes big capacity and send electricity, saved the circuit corridor, and compares with three doubles, iron tower weight saving about 20% has reduced cost of production, and social benefit and economic benefit are obvious.
2. be circular or polygonal Taper Pipe because the plurality of sections steel pipe of the utility model formation tower bar is the cross section, caliber is up-small and down-big, and the end of epimere and the top of hypomere are connected.The shape of whole tower bar can obviously reduce body of the tower blast, good stability, and the basic root that can help limiting iron tower is opened, and reduces floor space, and its load-carrying properties are good.
3. because three layer conductor cross-arms in every group of lead cross-arm of the utility model can be to extend gradually from top to bottom, adopt " umbrella shape " hanging wire mode, perhaps its upper strata cross-arm of three layer conductor cross-arms of every group of lead cross-arm and lower floor's cross-arm are short, the intermediate layer cross-arm is long, adopt " cydariform " hanging wire mode, and the cross-arm monomer adopts hexagon Taper Pipe or box-structure, the production cycle has been shortened in simple, the easily processing of this reasonable in design, and convenient the installation.
