Abstract

The invention discloses an overhead line pole cable suspension bracket, which includes a mounting seat and a plurality of wire harnessing mechanisms arranged on the mounting seat; The upper jacket is arranged on the upper part of the lower jacket and is detachably connected with the lower jacket through bolts, a wedge-shaped block is slidably arranged between the support plates, and a top tightening screw is movably connected to the lower part of the wedge-shaped block; In the initial state, the lower end of the strut is located in the middle of the wedge-shaped block. When the cable slides left and right in the inner jacket, the friction between the cable and the inner jacket drives the support rod at the lower part of the inner jacket to slide left and right on the wedge block. When the support rod slides left and right, the cross section of the wedge block drives the inner jacket upward. The movement increases the clamping force between the inner jacket and the cable, thereby avoiding the sliding of the cable; and through the setting of the inner jacket, it is convenient to adjust the pre-tightening force of the cable harness mechanism on the cable.
