Abstract

The utility model relates to the electric transmission and transformation technology field, and in particular relates to a multifunctional hook used for replacing an insulator in a power overhead transmission line. According to the multifunctional hook of the utility model, a first hook, a second hook and a third hook are formed by bending a steel bar, are uniformly fixed by welding below a ring, and are arranged opposite to each other; the third hook is used for hanging the insulator; and the third hook is arc-shaped, and the diameter of the third hook is less than that of a nut at the upper end of the insulator. Compared with conventional operation, the multifunctional hook of the utility model makes disassembling or assembling the insulator more time-saving and easier to use. The multifunctional hook of the utility model is simple in structure and low in cost, and can be widely used for replacing the insulator in the power overhead transmission line or lifting the maintenance tool of the transmission line.

Description

Multifunction hook

Technical field

The utility model relates to and send power transformation technical field, specifically relates to a kind of electricity overhead power transmission line and changes the Multifunction hook that insulator uses.

Background technology

While changing insulator at present in transmission line, be generally insulating cord looper, then will walk three, protection rope for conductor, action bars (write off) tie up on insulating cord, the method binding trouble and time-consuming longer.In the time changing insulator, need with rope bolt jail insulator, this easily causes the first electrician's hand and the safe distance of charged object distance not in the time of charged for replacement, thereby causes personal injury accident.

Summary of the invention

The technical problems to be solved in the utility model is the deficiency existing for prior art, provide a kind of and Work tool more easily lift by crane while changing insulator, in the time removing and recover insulator, the safe distance of guarantee human body and charged object Multifunction hook.

A kind of Multifunction hook of the utility model is achieved by following technical proposals: a kind of Multifunction hook comprises suspension ring, the first hook, the second hook, the 3rd hook, and described the first hook, the second hook and the 3rd hook adopts reinforcing bar to bend to form and be the opposing uniform below that is weldingly fixed on suspension ring; Described the 3rd hook is for suspension insulator, and described the 3rd hook is the nut that circular-arc and diameter is less than insulator upper end.

A kind of Multifunction hook of the utility model has following beneficial effect compared with prior art: the utility model Multifunction hook adopts three-hook, is used for hanging three, protection rope for conductor and action bars.Complete after the lifting of Work tool, can be used to remove or installing insulating.While adopting Multifunction hook can solve the lifting problem of Work tool and dismounting insulator, human body and charging equipment are apart from not enough problem.Use the dismounting of the utility model Multifunction hook or installing insulating more time saving and energy saving than traditional operation, and easy to use simple and direct.A kind of Multifunction hook of the utility model is simple and practical, and cost is low, can be widely used in the lifting of electricity overhead power transmission line replacing insulator or transmission line maintenance mans utensil.

Brief description of the drawings

A kind of Multifunction hook of the utility model has following accompanying drawing:

Fig. 1 is a kind of Multifunction hook structural representation of the utility model;

Fig. 2 is that a kind of Multifunction hook of the utility model uses structural representation.

Wherein: 1, suspension ring; 2, the first hook; 3, the second hook; 4, the 3rd hook; 5, insulating cord; 6, suspension insulator.

Embodiment

Below in conjunction with drawings and Examples, a kind of Multifunction hook technical scheme of the utility model is further described.

As Figure 1-Figure 2, the utility model a kind of Multifunction hook comprises suspension ring 1, the first hook 2, the second hook 3, the 3rd hook 4, and described the first hook 2, the second hook 3 and the 3rd hook 4 adopts reinforcing bars to bend to form and be the opposing uniform below that is weldingly fixed on suspension ring 1; Described the 3rd hook is 4 for suspension insulator, and described the 3rd hook 4 is the nut that circular-arc and diameter is less than insulator upper end.

The first hook 2 and the second hook 3 are conventional hook-shaped.

Embodiment 1.

As shown in Figure 1, the first hook 2 described in the utility model, the second hook 3 and the 3rd hook 4 adopt reinforcing bars to bend to form and be the opposing uniform below that is weldingly fixed on suspension ring 1.

Described the 3rd hook is 4 for suspension insulator, and described the 3rd hook 4 is the nut that circular-arc and diameter is less than insulator upper end; The first hook 2 and the second hook 3 are conventional suspension hook shape.

When use, adopt the utility model three-hook Multifunction hook, on three hooks, hang three, protection rope for conductor, action bars and insulator, complete after the lifting of Work tool, can be used to remove or installing insulating.While changing insulator, the utility model Work tool is more easily lifted by crane, removing or the installing insulating period of the day from 11 p.m. to 1 a.m, the utility model Multifunction hook can ensure the safe distance of human body and charged object.

Claims

1. a Multifunction hook, comprise suspension ring (1), the first hook (2), the second hook (3), the 3rd hook (4), it is characterized in that: described the first hook (2), the second hook (3) and the 3rd hook (4) employing reinforcing bar bend and form and be the opposing uniform below that is weldingly fixed on suspension ring (1); Described the 3rd hook (4) is for suspension insulator, and described the 3rd hook (4) is the nut that circular-arc and diameter is less than insulator upper end.

2. Multifunction hook according to claim 1, is characterized in that: the first hook (2) and the second hook (3) are conventional hook-shaped.
