Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line mechanical equipment, and in particular relates to an anti-theft structure for a flexible anti-falling device of an overhead power transmission line tower. Background Art

[0002] Overhead transmission line fall prevention devices are the ultimate safety guarantee for line construction and maintenance personnel. Their effective operation directly impacts the lives of those working at height. Flexible fall prevention devices generally consist of steel strands, a fixture connecting the strands to the tower, an adjustment device (turnbuckle) for strand tensioning, and a sway arrester. During installation, the turnbuckles are installed at the bottom of the tower, close to the ground. Climbing spikes are located at the bottom, making it easy for people to climb and access the turnbuckles. The turnbuckles consist of two threaded pairs, one left-handed and one right-handed. Tightening or loosening the two pairs adjusts the connection length. Installation and adjustment tools are simple, strong rods that are easily accessible. However, this poses risks to their safe and effective operation, such as a lack of anti-theft features, which hinders subsequent safe operation. Utility Model Content
