Abstract
The utility model discloses an insulated rope ladder for overhead power transmission lines. The insulated rope ladder is characterized by comprising vertical columns, cross rods, hooks, steel wire ropes and steel-wire-rope locking device, wherein two vertical columns and one cross rod are welded to form a horizontal-H-shaped frame structure; the vertical columns are internally provided with through holes; one end of each vertical column is provided with a concave hole, and the other end of each vertical column is provided with a convex structure; the plurality of horizontal-H-shaped frame structures are connected with one another in an inserting manner to form the ladder; the steel wire ropes are threaded in through holes in the vertical columns and are tightened by the steel-wire-rope locking devices to form a rigid ladder structure; the hooks are connected with the top end of one horizontal-H-shaped frame structure at the uppermost part. The insulated rope ladder disclosed by the utility model has the advantages that the principle and the structure are simple, the carry is convenient, and the use is safe; operators use the rope ladder when falling to the guide-line side by composite insulator strings in the maintenance process, so that the stability degree of the operators in the passing process is greatly improved.
