Description

Technical Field

[0001] The present application relates to the technical field of electric power engineering construction, and in particular to a copper-clad steel welding auxiliary tooling. Background Art

[0002] In the field of power engineering construction, electrical grounding usually uses copper-clad steel materials as the main grounding material. During grounding construction, a longer copper-clad steel material is usually used as a conductor and a short copper-clad steel material is used as a grounding electrode. After the grounding electrode and the conductor are welded and fixed, tools are used to insert the grounding electrode into the stratum to achieve a good grounding protection effect.

[0003] With regard to the existing copper-clad steel welding technology, an exothermic welding method is often used, in which the grounding electrode and the wire are plugged into a welding mold, and solder is used to perform an exothermic reaction in the welding mold to achieve a welding effect; but since the raw materials of the copper-clad steel material are generally disc-shaped, they need to be straightened before they can be constructed; but the modulated copper-clad steel material often still has stress, which causes deformation when the wire and the grounding electrode are welded, a gap is generated at the welding position, and the welding water flows out to cause the connector to collapse, resulting in low welding quality of the copper-clad steel grounding material. Utility Model Content

[0009] By adopting the above technical scheme, when welding the copper-clad steel grounding material, the wire is placed in the fixing assembly, the limiting assembly clamps and fixes the wire, and the adjusting assembly supports the two sets of fixing assemblies, so that the wire is fixedly placed on the clamping mechanism. At the same time, the wire and the grounding electrode are inserted into the inner cavity of the welding mold, and solder is placed in the welding mold. The welding is ignited, so that the solder melts in the inner cavity of the welding mold and melts the wire and the grounding electrode into one, and the wire and the grounding electrode are welded. The clamping mechanism is set to limit and fix the wire, thereby avoiding deformation of the wire under stress, so that when the wire and the grounding electrode are welded, a gap is generated at the welding position, and the welding water flows out to cause the connector to collapse, which is convenient for improving the welding quality of the copper-clad steel grounding material.

[0010] In a specific possible implementation scheme, the adjustment assembly includes a first mounting beam, a second mounting beam, an adjustment rod and a fixing bolt; two connecting beams of one group of the fixing assemblies are fixedly connected to the side wall of the first mounting beam; two connecting beams of another group of the fixing assemblies are fixedly connected to the side wall of the second mounting beam; the connecting beams of the two groups of the fixing assemblies are both located on the same side of the first mounting beam or the second mounting beam;

[0017] In a specific possible implementation scheme, the fixing assembly also includes a side baffle, which is fixedly arranged on one side of the abutment block close to the limiting groove, and the side baffle is located between the two limiting grooves, and the top wall of the side baffle is arranged higher than the top wall of the abutment block.

[0018] By adopting the above technical solution, when the diameter of the wire is relatively thick, the side baffle forms a lateral limit on the side wall of the wire, so that the wire with a large diameter can also be stably clamped in the limit groove, which is convenient for improving the clamping stability of the wire.
