Auxiliary fixture for ground electrode installation

Abstract

The invention discloses an auxiliary fixture for ground electrode installation, which is used for installing a ground electrode. The ground electrode is angle steel, the acute angle side of the groundelectrode is the inner side, and the obtuse angle side of the ground electrode is the outer side. The auxiliary fixture consists of an inner fixture and an outer fixture. The inner fixture includes an inner folding plate matching the inner side of the ground electrode. The two side edges of the inner folding plate are wider than the two side edges of the ground electrode. An inner hitting table is welded to the inner side of the inner folding plate. First threaded holes are respectively arranged in the top corners of the two side edges of the inner folding plate. The outer fixture includes anouter folding plate matching the outer side of the ground electrode. The two side edges of the outer folding plate are wider than the two side edges of the ground electrode. An outer hitting table iswelded to the outer side of the outer folding plate. Second threaded holes are respectively arranged in the top corners of the two side edges of the outer folding plate. By using the inner fixture and the outer fixture to clamp the ground electrode, an appropriate hitting height is realized, and therefore, the ground electrode can be quickly installed in place.

Description

technical field [0001] The invention belongs to the field of electric working tools, and in particular relates to an auxiliary jig for installing a ground electrode. Background technique [0002] During the construction of power lines and substation projects, in order to protect the power grid and substation equipment from unexpected fault currents or prevent damage caused by lightning, it is necessary to lay grounding devices. Among them, the most difficult construction is the grounding electrode. The currently used grounding electrode is 50 or 63 angle iron, 2.5 meters in length, and is made of galvanized. In the construction specification, a 2.5-meter-long grounding electrode should be driven into the ground, and its top is 0.8 meters from the ground. Lines and substation projects often need to bury multiple grounding electrodes, and at least 4 grounding electrodes must be buried. When burying the ground electrode, the top of the ground electrode is generally hit with a ...

Problems solved by technology

When burying the ground electrode, the top of the ground electrode is generally hit with a sledgehammer to make it go below the ground. Since the height of the ground electrode is higher than the height of the human body after the ground electrode is erected, using a sledgehammer to hit the top increases the difficulty of construction and is time-consuming and laborious.
