Abstract

The utility model discloses a pair of 10KV insulated stretching wire type scissors, mainly comprising the pair of scissors, wherein the handle of the scissors on one side and an operating rod on the corresponding side have an included angle, the operating rod is provided with the insulated stretching wire, a tension spring is arranged between a scissors blade and the operating rod or the knife handle, the operating rod on the other side is provided with a hanger, and the operating rod is an epoxide resin insulating rod. In the pair of 10KV insulated stretching wire type scissors, the operating rod on one side and the handle have an included angle, the operating rod is provided with the insulated stretching wire, the tension spring is arranged between the scissors blade and the operating rod with the insulated stretching wire or the handle, and the pair of scissors is in the normally open state. When the pair of scissors is used, only one person is needed to align a scissors opening with a conductive wire to be cut and the operation of cutting the conductive wire is realized by pulling the insulated wire. The pair of 10KV insulated stretching wire type scissors is particularly suitable for the exit and operation of a 10KV overhead network user transformer, a switch and so on and for the live-wire operation of dismantling the 10KV earth potential.

Description

10KV insulation dragline type scissors

Technical field

The utility model relates to a kind of scissors, relates to the insulation dragline type scissors in a kind of 10KV of being applied in live wire specifically.

Background technology

At present, 10KV insulation scissors commonly used both at home and abroad has multiple, practical safe 10KV insulation scissors as shown in Figure 1, the blade of insulation scissors is clipped in the middle of two plate racks and is hinged on the both sides of support respectively, between two plate racks and two blades turning cylinder is arranged, blade and handle of a knife are hinged, two handle of a knifes are hinged, fitting operation bar on each handle of a knife, action bars of two staff's one man operations during use is opened earlier scissors simultaneously, aiming at the live wire that will shear again firmly cuts off live wire simultaneously, the structure of this insulation scissors is identical with the scissors of operation principle and shear-steel muscle, and its shortcoming is time-consuming, and heavyly is inconvenient to carry.

Summary of the invention

The purpose of this utility model just is to provide a kind of 10KV insulation dragline type scissors, uses this scissors time and labour saving under the situation that guarantees the livewire work personal security.

The purpose of this utility model can realize by following measure:

The utility model mainly is made of scissors, wherein between the action bars of a side scissors handle of a knife and respective side angle is arranged, and establishes the insulation stay cord on the action bars, establishes extension spring between scissor blade and action bars or handle of a knife.

Above-mentioned 10KV insulation dragline type scissors is provided with hook on the opposite side action bars.

Above-mentioned 10KV insulation dragline type scissors, described insulation stay cord is a silk insulation rope, action bars is the epoxy resins insulation rod.

Above-mentioned 10KV insulation dragline type scissors, angle is 105 ° between described action bars and handle of a knife.

The utility model is owing to have angle between a side action bars and handle of a knife, dress insulation stay cord on the action bars, establish extension spring between the action bars of blade and tape insulation stay cord or handle of a knife, can make scissors be in normally open, only need a people that the scissors mouth is aimed at live wire to be sheared during use, the operation that pulling insulation rope just can realize cutting off lead.And the hook on the opposite side action bars can hang over scissors and form fulcrum on the lead, and handled easily insulation stay cord is cut off lead.Carrying out this operation with original accompanying drawing 1 scissors needs two staff in 1.5m, operation 2 hours.Only need operation personnel when using the utility model to carry out this operation, can be in the scope about 2 meters, operation 0.5 hour has increased job area, has remedied apart from defective, has saved labour intensity, has reduced production cost, is fit to promote.The utility model is particularly suitable for out of service at device such as 10KV overhead transmission line user transformers, switch, in the 10KV earth potential live operation of dismounting.The utility model is not limited to the 10KV livewire work, and effect is also fine in other livewire work.

Description of drawings

Fig. 1 is a structural representation of using scissors at present always;

Fig. 2 is the utility model structural representation.

The specific embodiment

The utility model is done with detailed description below in conjunction with drawings and Examples:

The utility model mainly is made of scissors as shown in Figure 2, wherein 3 angle is arranged between the action bars of a side scissors handle of a knife 2 and respective side, and the angle between action bars and handle of a knife is established insulation stay cord 6 greater than 90 ° on the action bars 3, and 3 of scissor blade 1 and action bars are established extension spring 5.

Specifically: the utility model 10KV insulation dragline type scissors, on the opposite side action bars, be provided with hook 4, described insulated conductor is a silk insulation rope, action bars is the epoxy resins insulation rod, best effect is that the angle of 2 on action bars 3 and handle of a knife is that included angle A is 105 °, promptly can keep scissors to be in normally open, can in operation, the power with minimum cut off live wire again.

In the utility model, extension spring can also be located between scissor blade and the handle of a knife.

Operation principle of the present utility model is as follows: in operation process, by the hook on the utility model action bars scissors is hung over and to form fulcrum on the lead, rely on operation insulation stay cord to cut off live wire again, the utility model is not limited in the 10KV livewire work.

Claims
