Embodiment 1

[0037] like Figure 1-2 , Figure 6-7As shown, an overhead line pole cable suspension bracket includes a mounting seat 1 and a plurality of wire harnessing mechanisms 2 arranged on the mounting seat 1. The mounting seat 1 is horizontally or vertically installed on one side of the pole 4, and the mounting seat 1 includes a vertical arm 101 and a connecting arm 102 arranged on one side of the vertical arm 101, and side plates 105 are arranged on both sides of the vertical arm 101; The lower jacket 204 on the upper part and the upper jacket 205 arranged on the upper part of the lower jacket 204 and detachably connected with the lower jacket 204 through bolts, the lower part of the lower jacket 204 is connected with the bottom plate 201 through a plurality of supporting plates 202, and the corresponding A wedge-shaped block 211 is arranged between the adjacent support plates 202. The wedge-shaped block 211 is a grooved plate structure with a low middle and high ends. Both ends of...

Embodiment 2

[0048] The difference from Example 1 is that as Figure 11 As shown, in this embodiment, when the mounting seat 1 is installed vertically, a support arm 109 is connected to one side of the electric pole 4, and the upper part of the support arm 109 is provided with a pressure plate 108, and the pressure plate 108 is fixed with the side plate 105 by bolts connect.

Abstract

The invention discloses a pole cable suspension bracket for overhead lines, which comprises a mounting seat and several wire harness mechanisms arranged on the mount seat; the wire harness mechanism includes a bottom plate arranged on the upper part of the connecting arm, a lower jacket arranged on the upper part of the bottom plate and The upper jacket is set on the upper part of the lower jacket and detachably connected with the lower jacket by bolts. There is a wedge-shaped block between the supporting plates, and its two ends are slidably arranged on the side wall of the supporting plate. The lower part of the wedge-shaped block is connected with a top Tighten the screw rod; the lower end of the support rod is against the wedge block, and in the initial state, the lower end of the support rod is located in the middle of the wedge 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, and when the support rod slides left and right, driven by the section of the wedge block, the inner jacket is driven 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 wire harness mechanism on the cable.

Description

technical field [0001] The invention belongs to the technical field of cable construction, in particular to an overhead line pole cable suspension bracket. Background technique [0002] At present, overhead cables are overhead conductors equipped with insulating layers and protective sheaths. They are produced by a special cable similar to the production process of cross-linked cables. They are a new transmission method between overhead conductors and underground cables. [0003] The existing overhead cable fixing structure includes a hoop sleeved on the outer surface of the utility pole and a lead wire clamping mechanism arranged on the left and right sides of the hoop. The connecting protrusions at both ends of the semicircular ferrule and the two semicircular ferrules are screwed together by bolts. The cable clamping device, the cable wire is arranged in the cable clamping device. Since the inner diameter of the semi-circular hoop is fixed, the clamping force of the hoo...
