A portable ground wire winding device

Abstract

The invention discloses a portable ground lead winding device, and mainly relates to the field of power construction equipment. The portable ground lead winding device comprises a U-shaped base. A cover plate is arranged at an opening of the base and provided with penetrating-out holes. Lifting rods are arranged in the base and provided with first connecting rods. A second connecting rod is hingedto each first connecting rod. Each first connecting rod and the corresponding second connecting rod are both matched with the corresponding penetrating-out hole. The ends, away from the first connecting rods, of the second connecting rods upwards stretch out of the penetrating-out holes. A rotating shaft is arranged on each second connecting rod and sleeved with a lead winding shell. A groove isformed in each lead winding shell. An upper lead stop plate is arranged on each rotating shaft. Limiting grooves are formed in the cover plate. The distance between the limiting grooves and the penetrating-out holes is matched with the length of the positions between the second connecting rods and the upper lead stop plates. The upper lead stop plates can be placed in the limiting grooves. The portable ground lead winding device has the beneficial effects that before the climbing process, workers do not need to move a ground lead out of the lead winding device in advance, the ground lead is not prone to being locked on the lead winding device, great convenience is achieved, construction efficiency is improved, and the ground lead can be wound around the lead winding device quite conveniently.

Problems solved by technology

After the relevant isolation switch is opened, in order to prevent accidental pulling and closing of the electrical equipment in use, resulting in a sudden power failure of the maintenance equipment and threatening the safety of the maintenance workers, it is necessary to close the grounding knife for all aspects that may be sent to the power failure equipment. Gate or install grounding wire

A complete set of three-phase short-circuit grounding wires is composed of multi-strand annealed copper wires with transparent sheaths, and the weight often reaches more than 10 kg. When the winding shafts wrapped with the grounding wires are transported to the work site, in order to facilitate placement, they are placed vertically. During the working process, when the staff climb up with the ground wire on their backs, they need to remove the ground wire from the winding device placed upright, so that many ground wires are coiled on the ground, which will hinder the movement of other staff in the past. If the grounding wire is not removed in advance, the staff needs to continuously pull the grounding wire to separate it from the winding device during the climbing process. During the pulling process, the grounding wire is easily strangled on the winding device, resulting in lockup. Other workers need to manually pull the grounding wire in the opposite direction to loosen the winding with the winding device, and it can be detached from the winding device, which is troublesome. If it is dumped and placed, you need to find a fixed support to fix the winding shaft , To prevent unnecessary rolling, multiple winding shafts need to find multiple fixed supports, which is more troublesome; after the work is finished, the coiling is cumbersome and time-consuming. It is extremely inconvenient to use next time, and the coiling methods of on-site personnel are different, and the storage is not neat at ordinary times, which also seriously affects the standardized management of substation safety tools.
