Abstract
The invention discloses a dual-hook device for an insulating ladder. The dual-hook device comprises hooks, a sleeve, a crank arm and hoops. The dual-hook device is used for mounting the insulating ladder in hot-line work of a power transmission line; one end of the insulating ladder is suspended on a lead when the device is used; two legs at the other end of the insulating ladder are put inside the two hoops of the device; the hook A (1) and the hook B (2) are suspended on an iron tower; and the connecting angle between the insulating ladder and the iron tower can be conveniently adjusted due to the fact that the crank arm is arranged on the device. Thus, the dual-hook device for the insulating ladder is safe and reliable, convenient to use, simple to machine and low in cost.
Description
Technical field
The present invention relates to a kind of insulated ladder fastening devices of power transmission lines overhauling.
Background technology
At present, the insulated ladder that power transmission lines overhauling uses, one end is hooked on wire, and other end rope is fixed on steel tower, and often ladder only has one leg to contact with steel tower, uses very inconvenient, also dangerous.
Summary of the invention
Object of the present invention overcomes deficiency of the prior art exactly, and provides a kind of two hooking devices facilitating fixed insulation to put down ladder.
Technical scheme of the present invention is to achieve these goals:
The two hook of a kind of insulated ladder, be made up of hook, sleeve, connecting lever, anchor ear, it is characterized in that: one end and the sleeve C (3) of hook A (1) weld together, one end and the sleeve D (4) of hook B (2) weld together, connecting lever (5) is installed with in sleeve C (3), sleeve D (4), anchor ear (8) is housed at the two ends of connecting lever (5) and cover has screw thread (6), with nut (7) on screw thread (6), the other end of anchor ear (8) is equipped with screw (9), with nut (7) on screw (9).
As optimization, the two hook of above-described insulated ladder, it is characterized in that: hook A (1) has a > shape curved (10), hook B (2) has a < shape curved (11).
As optimization, the two hook of above-described insulated ladder, is characterized in that: hook A (1) has a S shape curved (12).
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), hook B (2) hang on steel tower, then four nuts (7) are tightened.Owing to this device there being connecting lever (5), the connection angle of insulated ladder and steel tower easily can be adjusted.
The present invention's beneficial effect is compared to existing technology:
Safe and reliable, easy to use, processing is simple, and cost is low.
