Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of four loops to be total to frame iron tower with tower, the production cycle has been shortened in its simple in structure, easy processing, and convenient the installation, has saved the circuit corridor, has alleviated shaft tower weight.
For solving the problems of the technologies described above, the technical solution of the utility model is: four loops are 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 comprises one deck ground wire cross-arm of being located at described tower masthead portion and is located at two groups of lead cross-arms of described ground wire cross-arm below, 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 each cross-arm monomer comprises 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 suspension arrangement.
As a kind of optimized technical scheme, described suspension arrangement comprises fixedlys connected with described Taper Pipe port and with the thread gripping-board of port closed, is provided with the hanging wire hole on described thread gripping-board.
As a kind of optimized technical scheme, three layer conductor cross-arms in described every group of lead cross-arm extend from top to bottom gradually, and three layer conductor cross-arms in perhaps described every group of lead cross-arm shorten from top to bottom gradually.
As a kind of optimized technical scheme, described plurality of sections steel pipe 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 two groups of lead cross-arms, 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, every group of lead cross-arm can set up 220kV double loop high-voltage line, and two groups of lead cross-arms can set up 220kV four loop high-voltage lines.So the utility model realizes big capacity and send electricity, saved the circuit corridor, and compares with two doubles, iron tower weight saving about 10% has reduced cost of production.
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 the lengthening gradually from top to bottom of three layer conductor cross-arms in every group of lead cross-arm of the utility model adopts " umbrella shape " hanging wire mode, perhaps three layer conductor cross-arms in every group of lead cross-arm shorten from top to bottom gradually, adopt " fall umbrella shape ".And each cross-arm monomer comprises that the cross section is hexagonal Taper Pipe, and the production cycle has been shortened in simple, the easily processing of this reasonable in design, and convenient the installation.
