Description
Technical field
The utility model relates to the insulated ladder fastening devices that a kind of power transmission lines overhauling is used.
Background technology
At present, the insulated ladder that power transmission lines overhauling uses, an end is hooked on wire, and the other end is fixed on steel tower with rope, and often ladder only has one leg to contact with steel tower, uses very inconvenient, also dangerous.
The utility model content
The purpose of this utility model overcomes deficiency of the prior art exactly, and a kind of two hooking devices that facilitate the flat ladder of fixed insulation are provided.
The technical solution of the utility model is to achieve these goals:
The two hooks of a kind of insulated ladder, by hook, sleeve, connecting lever, anchor ear, formed, it is characterized in that: an end and the sleeve C (3) of hook A (1) weld together, an end and the sleeve D (4) of hook B (2) weld together, in sleeve C (3), sleeve D (4), be installed with connecting lever (5), anchor ear (8) is equipped with at the two ends of connecting lever (5), also cover has screw thread (6), screw thread (6) is upper with nut (7), the other end of anchor ear (8) is equipped with screw (9), and screw (9) is upper with nut (7).
As optimization, the two hooks of above-described insulated ladder is characterized in that: on hook A (1), one>shape curved (10) is arranged, on hook B (2), one<shape curved (11) is arranged.
As optimization, the two hooks of above-described insulated ladder, is characterized in that: on hook A (1), a S shape curved (12) is arranged.
During use, one end of insulated ladder is hung on wire, two legs of the insulated ladder other end are placed in two anchor ears (8) of this device, will link up with A (1), the hook B (2) hang on steel tower, then four nuts (7) are tightened.Due to connecting lever (5) being arranged on this device, can easily adjust the connection angle of insulated ladder and steel tower.
The utility model beneficial effect compared to existing technology is:
Safe and reliable, easy to use, processing is simple, and cost is low.
