Assembled cross arm structure applied to electric tower

Abstract

The invention discloses an assembled cross arm structure applied to an electric tower, and relates to the technical field of electric iron components, in particular to the assembled cross arm structure applied to the electric tower, which comprises a first cross arm assembly and the electric tower, and the left end and the right end of the first cross arm assembly are fixedly connected with connecting tenons; first connecting edges are fixedly connected to the upper and lower surfaces of the left and right ends of the first cross arm assembly, second cross arm assemblies are connected to the left and right ends of the first cross arm assembly, and connecting mortises are formed in the ends, close to the first cross arm assembly, of the second cross arm assemblies. According to the assembled cross arm structure applied to the electric tower, the cross arm is designed to be of an assembled structure, components of the cross arm can be transported to a high position firstly, then the components of the cross arm are assembled, the size of the cross arm in the carrying process is reduced, the carrying difficulty is lowered, meanwhile, a double-cross-arm structure is adopted, the wind resistance of the cross arm under the condition of strong wind is improved, and the service life of the cross arm is prolonged. And the cross arm is prevented from being damaged by strong wind.

Description

Technical field [0001] The present invention relates to the field of electricity ferrous, specifically an assembled cross-bau structure applied to a tuber. Background technique [0002] The tower of the overhead transmission line is used to support the support structure of the wire and the lightning line. Make the wires to the ground, the land object satisfies the limit request, and can withstand the wire, lightning line, and its own load and external load, the power tower is generally divided into: wine cup, cat head, upper-character, dry word Five types and barrels, according to the purpose: Hezhao Tower, Linear Tower, Corner Tower, Transposition Tower (Replacement Wire Phase Position Tower), Terminal Tower and Crossing Tower, etc., their structural features are all kinds of tower types A space truss structure, the rod is mainly composed of single angle steel or combined angular steel. The horizontal is an important part of the electric tower, which is used to install insulator...

AI Technical Summary

Problems solved by technology

[0003] The existing cross-arm members are mainly welded by a single equal-sided angle steel or a combination of angle steel. The entire cross-arm structure is a whole, and the cross-arm is relatively large. It is difficult for personnel to transport the cross-arm to high altitude. At the same time, the wind resistance of a single cross-arm is poor, and it is easily damaged by the wind in strong winds. The structural strength is not high enough, and the angle steel cross-arm has poor insulation, frequent lightning conduction accidents, frequent lightning tripping accidents, and easy to rust The corrosion resistance is weak, the strength of the porcelain cross-arm is not enough, and the bending resistance is insufficient. Therefore, we provide an assembled cross-arm structure applied to the electric tower
