Abstract

The utility model provides a change promotion instrument of single wire insulator of 110kV with electricity, relates to the transmission line field, and its structure is: the both ends of insulating arm -tie all are provided with the spill draw -in groove, are provided with the opening on the insulating arm -tie, and the positive centre of insulating arm -tie is provided with the screw, and the U -loop passes through the bolt fastening in the screw of insulating arm -tie, and the top of U -loop is fixed with the connecting rod, and the backing plate has been cup jointed on the top of connecting rod, and the connecting rod end is provided with the screw nut. The utility model has the advantages of the utility model discloses the simple installation, low in labor strength, operation safety, the reliability is high, and simple structure, light in weight are convenient for operate, the 110kV circuit architomy wire big discrepancy in elevation, big shelves have been realized and have changed apart from the electrified of sharp insulator chain that the security of assurance personnel and equipment has reduced because of the economic loss that interruption maintenance led to the fact, shortens emergency time, reduction operation personnel intensity of labour, its tensile strength is high, and easy operation is laborsaving, and the practicality is strong.

Description

A kind of hoisting tool of charged for replacement 110kV single conductor insulator
one, technical field
The utility model relates to transmission line field, particularly a kind of hoisting tool of charged for replacement 110kV single conductor insulator.
two, background technology
For ensureing transmission line power supply continuity and reliability, fortune inspection personnel need timely charged for replacement faulty insulator.But the conventional method of replacing linear insulator string under electrification uses assembly pulley, but the method is only applicable to little span straight line pole.During as run into Great span, large span situation, using assembly pulley to need a large amount of manpower and materials, being difficult to more change jobs, even having had cord break, risk that wire drops ground.Therefore, explore a kind of lifter that can replace changing Great span, large span linear insulator chain, to reduce wire drop ground risk and reduce manpower and materials drop into imperative.
three, summary of the invention
A kind of hoisting tool of charged for replacement 110kV single conductor insulator is provided for the problems referred to above the utility model, its structure is: the top of insulation hook (1) is provided with screw (2), U-loop (3) is fixed in the screw (2) of insulation hook (1) by bolt (7), the top of U-loop (3) is fixed with connecting rod (4), the top of connecting rod (4) is socketed with backing plate (5), and connecting rod (4) end is provided with screw nut (6).
Occupation mode of the present utility model: top of the present utility model is backed out nut (6) and be socketed on the cross-arm of electric pole, then to screw on nut (6), electric wire is placed in insulation hook (1), finally turn nut (6), connecting rod (4) and insulation hook (1) are mentioned, electric wire is mentioned by insulation hook (1), and a locator just replaceable wire insulation brought up to by electric wire.
The beneficial effects of the utility model are: the utility model simple installation, and labour intensity is low; Security of operation, reliability is high, and structure is simple, lightweight convenient operation; Achieve the charged for replacement of the large discrepancy in elevation of 110kV circuit architomy wire, large span linear insulator chain, ensure the fail safe of personnel and equipment, decrease the economic loss because interruption maintenance causes, shorten emergency repair time, reduce operating personnel's labour intensity; Its tensile strength is high, simple to operate, laborsaving, practical.
four, accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: hook of 1, insulating, 2, screw, 3, U-loop, 4, connecting rod, 5, backing plate, 6, nut, 7, bolt.
five, embodiment
Embodiment 1, a kind of hoisting tool of charged for replacement 110kV single conductor insulator, its structure is: the top of insulation hook (1) is provided with screw (2), U-loop (3) is fixed in the screw (2) of insulation hook (1) by bolt (7), the top of U-loop (3) is fixed with connecting rod (4), the top of connecting rod (4) is socketed with backing plate (5), and connecting rod (4) end is provided with screw nut (6).
