Ground wire hitching device convenient for hitching

Abstract

The invention discloses a ground wire hitching device convenient for hitching, and aims to provide a ground wire hitching device capable of facilitating alignment of a wire and a wire clamping opening of a wire clamping seat, and effectively solving the problem that in the process of rotating a screw, the whole wire clamp seat is prone to rotating and translating, and consequently the grounding wire is difficult to hitch. The device comprises: an insulating rod; a wire clamp seat comprising an upper clamping arm, a lower clamping arm and a side connecting arm; a movable pressing plate, wherein a vertical guide rail is arranged on the side connecting arm, and the movable pressing plate slides up and down along the vertical guide rail; a screw rod, wherein a vertical threaded hole is formed the lower clamping arm, the screw rod is in threaded connection with the vertical threaded hole, the upper end of the screw rod is rotationally connected with the movable pressing plate, and the screw rod is connected with the insulating rod; and an anti-rotation limiting structure comprising a strip-shaped guide hole formed in the lower surface of the upper clamping arm, a sliding block sliding along the strip-shaped guide hole and a limiting guide flat plate located below the upper clamping arm, wherein the limiting guide flat plate is connected with the sliding block.

Description

technical field [0001] The invention relates to a grounding device, in particular to a grounding wire hooking device which is suitable for use on a wire with a square cross section and is convenient for hooking. Background technique [0002] The current spiral grounding clamp device generally includes an operating lever; a clamp seat, which includes an upper clamp arm, a lower clamp arm and a clamping opening formed between the upper and lower clamping arms; a movable pressing plate, which is located in the clamping opening , screw, the screw is fixed on the upper end of the operating rod, and the screw is arranged on the clamp seat for driving the movable platen to move up and down. At present, the application process of this spiral grounding clamp device on the wire with a square cross section is as follows (for example, copper bars, aluminum bars and other wires used in outdoor substations), fix one end of the grounding wire on the wire clamp seat, and then, Lift the wir...
