Description

Technical Field

[0001] This utility model relates to the field of power grid equipment technology, and in particular to an electric dual-purpose four-wheeled vehicle for power transmission and maintenance of horizontal double-split conductors. Background Technology

[0002] Horizontal double-split conductors are a common type of split conductor. Specifically, in the same phase of a transmission line, a single conductor is split horizontally by a certain distance to form two parallel sub-conductors. These sub-conductors are connected by spacers or other connectors to maintain a fixed distance (usually 200-400 mm) and share the power transmission task. The two sub-conductors are arranged horizontally side by side in space.

[0003] Overhead cranes are important tools in power transmission line maintenance, mainly used on 220kV-330kV horizontal double-split lines. They can perform tasks such as replacing and adjusting spacers, vibration dampers, and repairing conductors. However, existing overhead cranes are prone to collisions between the wheels and frame and spacers when crossing obstacles, leading to wheel deformation and loosening of transmission components. They also suffer from structural redundancy and excessive weight. Utility Model Content
