Abstract

The invention provides an electric cross arm installing frame. A C-shaped frame-like lantern ring is included. A C-shaped pipe-like insulating inner pad is arranged on the inner wall of the lantern ring. The height of the insulating inner pad is larger than that of the lantern ring. The two ends of an opening of the lantern ring are provided with flat-plate-shaped protruding plates vertically connected with the lantern ring. The protruding plates are correspondingly provided with avoiding holes, bolts penetrate through the avoiding holes of the protruding plates for locking, a damping spring is vertically arranged on the outer wall of the lantern ring, and the other end of the damping spring is vertically connected with a flat-plate-shaped installing plate. By implementation of the electric cross arm installing frame, good insulating performance is achieved, good damping performance is achieved, large alternating stress can be borne, and the service life is prolonged.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an electric cross-arm installation frame. Background technique [0002] The power cross arm is installed on the pole or tower to fix the power fittings of the insulator, and is the main supporting member for bearing the weight of the wire. The power cross-arm often needs to be fixed on the pole with a mounting bracket, so as to support the insulator and the wire. However, the existing power cross-arm installation frame is more traditionally designed, which not only has insufficient insulation isolation from the electric pole, but also has poor shock absorption capacity. In this way, the installation frame is prone to electric leakage, and the power cross-arm and electric wires are likely to generate alternating stress after being affected by the wind force, causing the power cross-arm installation frame to break and fall off easily, and the service life is not long.
