Abstract

Transmission line suspension insulator chain changes operation fixture. Because the bird blocking plates are arranged on the tower pole of the power transmission line, the bird blocking plates need to be removed firstly when the tower pole is replaced, and the bird blocking plates are placed at positions which do not influence the work, so that the replacement efficiency of the insulator string is greatly reduced. The utility model discloses the constitution includes: u-shaped plate (1) and branch (3), the U-shaped plate with the branch welding, upper and lower both ends board (6) of U-shaped plate be the U-shaped structure, the upper and lower both ends board department of U-shaped plate seted up slide opening (5), the slide opening position of upper and lower both ends board is just right, has all worn set screw (2) between every two relative slide openings, and set screw both ends threaded connection have the nut. The utility model is used for transmission line insulator chain that dangles changes the operation.

Description

Transmission line insulator chain that dangles changes operation fixture

Technical Field

The utility model relates to a transmission line insulator chain that dangles changes operation fixture.

Background

With the increase of the operation time of the insulator string on the power transmission line, the number of aged, deteriorated and zero-valued insulators is gradually increased, and the insulators need to be overhauled and replaced.

Disclosure of Invention

The utility model aims at providing a transmission line insulator chain that dangles changes operation fixture.

The above purpose is realized by the following technical scheme:

the utility model provides a transmission line insulator chain that dangles changes operation fixture, transmission line insulator chain that dangles change operation fixture include U-shaped board and branch, the U-shaped board with branch welding, the upper and lower both ends board of U-shaped board be the U-shaped structure, the upper and lower both ends board department of U-shaped board seted up the slide opening, the slide opening position of upper and lower both ends board is just right, all worn set screw between every two relative slide openings to set screw both ends threaded connection have the nut.

The electric transmission line suspension insulator string replacing operation fixture is characterized in that a fixing rod perpendicular to the supporting rod is welded at the end of the supporting rod.

Has the advantages that:

1. the utility model discloses can fix it on the tower pole cross arm, need not demolish the change operation that can realize insulator chain with the fender bird board simultaneously.

2. The utility model discloses fix on the cross arm after, through hanging wire rope on the dead lever, can guarantee that the device receives the effect of perpendicular decurrent power, the device is fixed and is formed quadrangle fixed knot structure on the cross arm simultaneously, can not take place crooked, can not produce the destruction to the fender bird board simultaneously.

Description of the drawings:

fig. 1 is a top view of the present invention;

FIG. 2 is a front view of the present invention;

FIG. 3 is a schematic structural view of the present invention in use;

in the figure: 1. a U-shaped plate; 2. fixing the screw rod; 3. a strut; 4. fixing the rod; 5. a slide hole; 6. an end plate; 7. a cross arm; 8. keep off the bird board.

The specific implementation mode is as follows:

example 1:

the utility model provides a transmission line insulator chain that dangles changes operation fixture, transmission line insulator chain that dangles change operation fixture include U-shaped board 1 and branch 3, the U-shaped board with branch welding, upper and lower both ends board 6 of U-shaped board be the U-shaped structure, the upper and lower both ends board department of U-shaped board seted up slide opening 5, the slide opening position of upper and lower both ends board is just right, has all worn clamping screw 2 between every two relative slide openings, clamping screw both ends threaded connection have the nut.

Example 2:

according to the fixture for replacing the suspension insulator string of the power transmission line in the embodiment 1, the end part of the support rod is welded with the fixed 4 rods perpendicular to the support rod.

The working principle is as follows: when the device is used, as shown in fig. 3, the device is sleeved on the cross arm, the fixing screw rods penetrate through the sliding holes in the end plates according to the position of the cross arm 8 to be located on two sides of the cross arm, nuts are connected to the upper end and the lower end of the fixing screw rods in a threaded mode, the supporting rod extends out of the bird blocking plate 9 at the moment, then the steel wire rope is bound on the fixing rod of the supporting rod, the operation of replacing the insulator string can be carried out, and the bird blocking plate does not need to be detached.

Claims
