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

The two hooks of insulated ladder
Technical field
The present invention 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 the lead, and the other end is fixed on the iron tower with rope, and often ladder has only one leg to contact with iron tower, uses very inconvenient, also dangerous.
Summary of the invention
Purpose of the present invention overcomes deficiency of the prior art exactly, and a kind of two hooking devices that make things convenient for the flat ladder of fixed insulation are provided.
Technical scheme of the present invention is to achieve these goals:
The two hooks of a kind of insulated ladder, formed by hook, sleeve, connecting lever, anchor ear, 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, be installed with connecting lever (5) in sleeve C (3), the sleeve D (4), the two ends of connecting lever (5) are equipped with anchor ear (8) and are with screw thread (6), have nut (7) on the screw thread (6), the other end of anchor ear (8) is equipped with screw (9), has nut (7) on the screw (9).
As optimization, the two hooks of above-described insulated ladder is characterized in that: have one on the hook A (1)〉shape curved (10), there is one<shape to bend (11) on the hook B (2).
As optimization, the two hooks of above-described insulated ladder is characterized in that: have a S shape to bend (12) on the hook A (1).
End with insulated ladder during use hangs on the lead, and 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 the iron tower, then four nuts (7) are tightened.Owing on this device connecting lever (5) is arranged, can easily adjust the connection angle of insulated ladder and iron tower.
The present invention's beneficial effect compared to existing technology is:
Safe and reliable, easy to use, processing is simple, and cost is low.
