The cable-blocking insulator comprises an insulator, one end of the insulator has a pressing plate, and the other end of the insulator is provided with a link fitting. The link fitting is provided with a clamp claw which is used for connecting a pole and tower angle steel in a clamping manner. The link fitting is provided with a locking push rod at a position corresponding to the clamp claw. A push head of the locking push rod is directed to the clamp claw. By the technical scheme that a link fitting is additionally arranged on the insulator, the cable-blocking insulator solves the problem that the insulator cannot be mounted and fixed. The insulator can be clamped on the pole and tower angle steel directly through the link fitting, is simple in structure and convenient to use, and is suitable for live-line work of an electric power circuit.
Description
Technical field
The utility model relates to the power circuit apparatus field, and particularly a kind of live line working is with keeping off the line insulator.
Background technology
Before the utility model proposes, an operation is arranged for installing the cable downlead additional in traditional live line working, this operation process is: at first punch at the shaft tower angle steel; Insulator is fixed on the described shaft tower angle steel with bolt by described hole then; At last the cable downlead is fitted on the described insulator and gets final product.But because with the tower structure complexity in many times overhead transmission lines of tower, the space is too little, so therefore aerial lift device with insulated arm can't can't punch the job position of delivering to of operating personnel's safety at the shaft tower angle steel, need uses the insulating bar mode of operation instead and carry out operation.Like this, the insulator of traditional structure can't use.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, to provide a kind of simple in structure and easy to operate live line working with keeping off the line insulator.
In order to realize above purpose, a kind of live line working that the utility model provides is with keeping off the line insulator, the insulator that comprises an end band pressing plate, the described insulator other end is provided with the connection gold utensil, described connection gold utensil is provided with the claw for clamping shaft tower angle steel, the position of corresponding described claw is provided with the locking push rod on the described connection gold utensil, and the top of described locking push rod is towards described claw.By add the technical scheme that connects gold utensil at described insulator, solved the problem that insulator can't install and fix, described insulator can directly be installed on the shaft tower angle steel by described connection gold utensil, and is simple in structure and easy to use.
In such scheme, described locking push rod is movably arranged on by being threaded on the described connection gold utensil.
In such scheme, the top of described locking push rod is provided with anti-skidding recess, to improve the clamping intensity of described connection gold utensil and shaft tower angle steel.
In such scheme, described connection gold utensil is provided with stiffener.
The beneficial effect that the technical scheme that the utility model provides is brought is: by add the technical scheme that connects gold utensil at described insulator, solved the problem that insulator can't install and fix, described insulator can directly be installed on the shaft tower angle steel by described connection gold utensil, and is simple in structure and easy to use.
The utlity model has characteristics such as simple in structure, easy to use.
Description of drawings

Among the figure, insulator 1, pressing plate 1a connects gold utensil 2, claw 2a, locking push rod 2b, anti-skidding recess 2b1, stiffener 2c, shaft tower angle steel 3.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model execution mode is described in further detail.
As shown in Figure 1, a kind of live line working that the utility model provides is with keeping off the line insulator, the insulator 1 that comprises an end band pressing plate 1a be connected gold utensil 2, the upper end of described connection gold utensil 2 links to each other with the other end of described insulator 1, described connection gold utensil 2 lower ends are provided with the claw 2a for clamping shaft tower angle steel 3, the position of corresponding described claw 2a is provided with locking push rod 2b on the described connection gold utensil 2, and the top of described locking push rod 2b is towards described claw 2a.By add the technical scheme that connects gold utensil 2 at described insulator 1, solved the problem that insulator 1 can't install and fix, described insulator 1 can directly be installed on the shaft tower angle steel 3 by described connection gold utensil 2, and is simple in structure and easy to use.
Above-mentioned locking push rod 2b is movably arranged on by being threaded on the described connection gold utensil 2.The top of described locking push rod 2b is provided with anti-skidding recess 2b1, to improve the clamping intensity of described connection gold utensil 2 and shaft tower angle steel 3.Described connection gold utensil 2 is provided with stiffener 2c.
Use of the present utility model is as follows:
At first, the operating personnel utilizes the metal fixture at insulating bar top to secure the above the middle part of insulator 1, mentions this retaining line insulator gently, and this retaining line insulator is lain in a horizontal plane on the cross-arm of shaft tower; Then, utilize insulating bar to adjust the position of this retaining line insulator, shaft tower angle steel 3 is entered between the claw 2a and locking push rod 2b of described connection gold utensil 2; Simultaneously, another operating personnel is hand-held insulating bar also, utilizes the metal sleeve spanner at insulating bar top to rotate described locking push rod 2b, and the side that makes locking push rod 2b withstand described shaft tower angle steel 3 is connected on the described shaft tower angle steel 3 fully until described connection gold utensil 2; At last, with insulating bar the cable downlead is put into described pressing plate 1a again, and fastening getting final product.
The utility model provides the technical scheme that connects gold utensil 2 by adding at described insulator 1, solved the problem that insulator 1 can't install and fix, described insulator 1 can directly be installed on the shaft tower angle steel 3 by described connection gold utensil 2, and is simple in structure and easy to use.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
