CN201877732U - Live line tool for fastening insulator nuts - Google Patents

Abstract

The utility model discloses a live line tool for fastening insulator nuts. The live line tool comprises an insulating rod, the upper end of which is provided with a rubber rod, and the tip of the rubber rod is provided with a nut sleeve. The live line tool consists of the insulating rod, the rubber rod and the nut sleeve and is simple in structure. As the rubber rod is flexible, the rubber rod can be bent by exerting force in different directions on the insulating rod when operating staff sheath the insulator nut with the nut sleeve. Consequently, nuts in directions on the insulator can be installed and overhauled.

Description

Tools for live tightening nuts of insulators

technical field

The utility model belongs to electric power maintenance tools, in particular to a tool capable of live maintenance of nuts on insulators.

Background technique

Overhead lines are all in the field, and many insulators are arranged on the overhead lines, and nuts are arranged on the insulators. After long-term exposure to wind, sun and other operations in nature, the nuts on the insulators often loosen, and even fall off. And now people can't do without electricity all the time, which requires the maintenance personnel to work live and tighten the nuts to reduce the loss of power failure.

Utility model content

The purpose of this utility model is to provide a tool for tightening the nut of an insulator with electricity, which can realize the maintenance of the nut on the insulator without power failure.

The technical scheme of the utility model is realized in the following manner: a tool for fastening the nut of an insulator with electricity, comprising an insulating rod, a rubber rod is arranged at the upper end of the insulating rod, and a nut sleeve is arranged at the end of the rubber rod.

An adjustment sleeve is arranged on the rubber rod, and the adjustment sleeve is connected with the adjustment rod.

The lower end of the insulating rod is provided with a rotary handle.

The utility model is composed of an insulating rod, a rubber rod and a nut sleeve, and its structure is simple. Because the rubber rod is flexible, when the operator puts the nut sleeve on the nut of the insulator, by applying forces in different directions to the insulating rod, the rubber rod can be bent, and then the insulator can be installed and repaired in different directions. nuts.

Description of drawings

Example 1

As shown in FIG. 1 , a tool for fastening the nut of an insulator with electricity includes an insulating rod 4 , a rubber rod 3 is provided at the upper end of the insulating rod 4 , and a nut sleeve 1 is provided at the end of the rubber rod 3 .

The use process of the utility model is as follows: the nut sleeve 1 is set outside the nut, and the operator rotates the rubber rod 3 to drive the nut sleeve to rotate and tighten the nut or replace the nut. Due to the different installation angles of the insulators, the directions of the nuts on the insulators are not exactly the same. By applying force to the insulating rod 4 by the operator, the rubber rod 3 can be bent to a certain extent, and then the nuts with different angles can be adjusted.

As shown in FIG. 2 , as a preferred solution of this embodiment, a rotating handle 6 is provided at the lower end of the insulating rod 4 . Sometimes the nut may be corroded and needs to be updated. At this time, when the nut sleeve 1 is driven by turning the rotary handle 6 to rotate, the active force on the nut is larger, and the corroded nut can be unscrewed.

Example 2

As shown in FIG. 3 , an adjustment sleeve 2 is provided on the rubber rod 3 , and the adjustment sleeve 2 is connected with the adjustment rod 5 . Other structures are with embodiment 1.

Due to the different orientations of the insulators, the directions of the nuts on the insulators are also very different. For the situation where the direction of the nuts is too large for the angle of the operator, this embodiment is especially suitable for adjusting the nuts installed at different angles. Its use process is as follows: pull the adjustment rod 5 to drive the rubber rod 3 to bend, and then adjust the direction of the nut sleeve 1, then put the nut sleeve 1 on the nut and twist it. According to the direction of the nut, various forces can be applied to the adjusting rod 5, so that the rubber rod can be bent in different degrees.

Claims (3)

1. the instrument of a charged fastening insulator nut comprises insulating rod (4), it is characterized in that: insulating rod (4) upper end is provided with rubber bar (3), and rubber bar (3) termination is provided with screw cap sleeve (1).
