Description

Technical Field

[0001] This utility model relates to the field of bending technology for the grounding lead of iron towers, specifically a bending device for bending the grounding lead of iron towers. Background Technology

[0002] Grounding leads are metal conductors that connect electrical equipment to the grounding electrode, serving to protect power transmission and transformation equipment. They are commonly used to connect the grounding terminals of transformers on iron towers to the grounding electrode. During foundation construction, the grounding electrode is pre-embedded around the foundation, and the grounding lead needs to be bent along the outer edge of the tower foundation to be close to the tower body and foundation.

[0003] There are two existing methods for bending lead wires: manual bending and mechanical bending. Manual bending often results in problems such as over-bending or under-bending, which may lead to incompatibility with the pre-installed position. In addition, manual bending is labor-intensive, time-consuming, and inefficient, which affects the construction progress. Mechanical bending involves setting up a processing platform and using electrical equipment to bend the lead wires. However, the processing equipment is large and heavy, making it inconvenient to carry to the construction site, which also affects the construction progress. Utility Model Content
