Abstract
The invention discloses a multi-prism cross arm, belonging to cross arms. The multi-prism cross arm structurally comprises a cross arm body and a line hanging plate, wherein the cross arm body is a multi-prism tapered pipe; the line hanging plate passes through the end part of the cross arm body; one end part of the cross arm body is provided with a connecting member, and the other side of the connecting member is provided with a fixing plate; the fixing plate is fixed with a cross arm connecting plate through a bolt; the cross arm connecting plate is welded on a master pole; the other end part of the cross arm body is provided with a seal plate; a line hanging ring is arranged at the outer side of the seal plate; and hardware fittings are arranged on the line hanging ring. Compared with the prior art, the multi-prism cross arm disclosed by the invention has the advantages that: because the cross arm body is the multi-prism tapered pipe, the tapered structure is beneficial to reducing self weight and cost and improving the bearing capability of the cross arm body; and the structure strength of the cross arm is increased because the cross arm is the octagonal tapered pipe; and therefore the invention has favorable popularization and application values.
Description
Technical field
The present invention relates to a kind of cross-arm, especially a kind of for many prism cross arms on the power transmission line steel pipe rod.
Background technology
In existing power transmission line steel pipe rod, with its different use occasion and conveying payload, mainly contain metal construction and cement rod-type, wherein the cement rod-type be owing to can not be used for the conveying of large electric weight, thus high pressure length apart from the electric power conveying facility in the metal constructions that adopt more.In the metal construction steel pipe pole, mainly formed with the cross-arm that is connected with mobile jib by the mobile jib that is connected with ground, in the manufacturing of reality was used, cross-arm commonly used was grooved and box cross-arm, and it is formed by top board, side plate, base plate and more stiffened panel assembly welding, the blanking number of packages is many, the blanking waste of side plate is large, and various thickness of slab mixes mutually, and welding capacity is large, waste wlding and man-hour, and the situation of cross-arm and cross-arm seat torsional deformation when user installation, often occurs.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of many prism cross arms for above-mentioned deficiency of the prior art, it is many prismatics conial tube that these a kind of many prism cross arms have the cross-arm body, this cone structure is conducive to reduce deadweight, reduce cost, and the supporting capacity of raising cross-arm body, cross-arm is octagonal taper rib pipe, has increased the characteristics of the structural strength of cross-arm.
The technical solution adopted for the present invention to solve the technical problems is: it comprises cross-arm body and thread gripping-board, described cross-arm body is many prismatics conial tube, described thread gripping-board passes in the middle of the end of cross-arm body, one end of described cross-arm body is provided with connector, the opposite side of described connector is provided with fixed head, described fixed head fixes by bolt and cross-arm junction plate, described cross-arm junction plate is welded on the mobile jib, the other end of described cross-arm body is provided with hush panel, the arranged outside of described hush panel has the hanging wire ring, be provided with gold utensil on the described hanging wire ring, be provided with stiffened panel between described connector and the cross-arm body.
