Abstract

The invention relates to a support frame for installing overhead transmission lines, and belongs to the technical field of installation of overhead transmission lines, which can solve the technical problem of complex detachment and replacement of connection rings in the prior art. The support frame includes a tower, a cross arm, connecting rings and fixing mechanisms; each connecting ring includesa lantern ring and a mounting post; each fixing mechanism includes a fixing member fixedly disposed on the cross arm and having a circular outer peripheral surface, and one end away from the cross arm, of the fixing member passes through the mounting post and is located in the lantern ring; and each fixing member includes an upper fixing column and a lower fixing column which are semi-circular incross section, wherein one end of the upper fixing column and one end of the lower fixing column are fixedly connected, and an elastic member is fixedly disposed between the other end of the upper fixing column and the other end of the lower fixing column. According to the support frame for installing the overhead transmission lines, detachable connections between the connection rings and the cross arm can be realized through the fixing mechanisms, so that installation and detachment of the connection ring are convenient; and the elastic members are disposed between the upper fixing columns and the lower fixing columns, so that the installation of the connection rings is more stable.

Description

technical field [0001] The invention relates to the technical field of installing overhead transmission lines, in particular to a support frame for installing overhead transmission lines. Background technique [0002] In the erection of power grids, overhead transmission line support frames are commonly used to erect and install power transmission cables. The support frames in the prior art mainly include pole towers and cross arms, and several connecting rings are installed on the cross arms. Cables, and the transmission cables between adjacent towers are erected through connecting rings. The connecting ring in the prior art is directly welded on the cross arm, and it is inconvenient to replace the connecting ring when the connecting ring is corroded by wind and rain for a long time. Contents of the invention [0003] The purpose of the present invention is to provide a support frame for installing overhead power transmission lines. The detachable connection between the ...
