The invention relates to an anti-off device for a grounding wire, which includes an anti-off fixing piece, a rope drum and a fixing buckle arranged at the lower end of the rope winding drum; the anti-off fixing piece includes a fixing shell and a strap; the winding The rope drum includes a cylinder body, a fixed shaft arranged on the axis of the cylinder body, a rope reel assembly arranged on the fixed shaft, and the rope reel assembly includes a scroll spring wound on the fixed shaft and a set On the wheel shaft of the outer ring of the scroll spring, one end of the scroll spring is fixedly connected to the fixed shaft, and the other end of the scroll spring is fixedly connected to the wheel shaft; There is a binding rope, one end of the binding rope is fixedly connected to the wheel shaft, the other end of the binding rope is connected to the anti-off fixture, and there are three rope winding assemblies and three anti-off assemblies. It has the characteristics of simple structure and convenient use, and also has the functions of wire traction, wire swing prevention, and ground wire fall-off prevention.
Description
technical field [0001] The invention relates to an anti-dropping device for grounding wires. Background technique [0002] In the field of electric power, the "State Grid Corporation of China Electric Power Safety Work Regulations" stipulates that when disconnecting equipment connectors with grounding wires, measures should be taken to prevent the grounding wires from falling off. Moreover, there will be swinging (jumping) during the de-guiding process of the wire, and the wire is in a free state, causing harm such as hurting people, shortening the safety distance, and damaging the insulating porcelain bottle. At present, in order to overcome the above defects, white cloth tapes are usually used in the industry to bind the conductive clip of the grounding wire and the connecting part of the live equipment. But this method is loaded down with trivial details to operate, and the fixing effect of lead wire is not high, if run into, dismantle ground wire operation, then increas...
