And the distribution overhead line is used as the most main power supply line in villages and mountainous areas, has high fault rate in the areas with severe operating conditions, and is mostly caused by the damage of old insulators on the lines. Therefore, timely replacement of old insulators is one of the effective measures for keeping the mountain area distribution overhead line running level. At present, the main method for replacing the linear rod insulator is that after a constructor gets on the rod, the insulator binding wire is untied, the wire is lifted by the shoulder, and then the old insulator is replaced. Because the distribution lines in mountain areas are erected in hilly mountain areas, sometimes need to cross rivers, the positions of towers are limited, the span can often reach 100-200 m, in addition, because adjacent rods often have large height difference, long wires are needed between the two rods, the wires often have large weight, the replacement of the wires can cause large burden on the shoulders of constructors, and the working efficiency is low.

The specific meaning of the above terms in embodiments of the present application will be understood in detail by those of ordinary skill in the art.

Referring to fig. 1, an auxiliary device for replacing a linear rod insulator provided in an embodiment of the application includes: the V-shaped rod 1, the wire clamp 2 and the fixing seat 3; the V-shaped rod 1 is formed by connecting a short rod 11 and a long rod 12, and the end part of the short rod 11 connected with the long rod 12 is rotatably arranged on the fixed seat 3; the wire clip 2 includes: the clamping seat 21, at least two spring plates 22 and a limiting piece 23; the clamping seat 21 is arranged on the short rod 11 far from the top of the long rod 12, and an open slot 24 is arranged on the clamping seat 21; the open slot 24 is used for placing a wire; the two spring plates 22 are respectively rotatably arranged at two sides of the top of the open groove 24, and the minimum distance between the two spring plates is smaller than the wire diameter of the wire; the limiting piece 23 is disposed at the top of the holder 21 and above the spring plate 22, for limiting the spring plate 22 from rotating away from the open slot 24.

Specifically, the short rod 11 is used for connecting the clamping seat 21, the long rod 12 is used as an operation handle, the intersection point of the two is used as a rotation axis to be arranged on the fixed seat 3, and the long rod 12 can be rotated to lift the lead on the short rod 11 with a small force through the lever principle. The open slot 24 on the holder 21 is a U-shaped slot, and the spring plate 22 is disposed in the slot, so that the wire can drive the spring plate 22 to rotate from top to bottom and then enter the open slot 24. By providing the stopper 23, when the wire slides out from top to bottom, the spring plate 22 cannot rotate to the outside due to the restriction of the stopper 23, thereby restricting the wire in the open slot 24. When the wire needs to be taken out of the open slot 24, the spring plate 22 is rotated towards the open slot 24, so that the space between the spring plates 22 is increased to enable the wire to be taken out; alternatively, the stopper 23 may be movably disposed, and when the spring plate 22 is required to be rotated in a direction away from the open groove 24, the stopper 23 may be moved away from the upper side of the spring plate 22.

Further, a locker 4 is also included; the latch 4 includes: a lock bolt (not shown) and a turning handle 41; the locking bolt is arranged on the fixed seat 3 and axially intersects with the V-shaped rod 1; the turning handle 41 is used to turn the locking bolt.

Specifically, the turning handle 41 is used to rotate the locking bolt, thereby adjusting the distance between the locking bolt and the V-shaped rod 1. When the wire is lifted to a required height through the V-shaped rod 1, the V-shaped rod 1 is fixed and cannot rotate by rotating the locking bolt.

Further, the fixing base 3 may be a metal base, including: a base 31 and a movable plate 32; the V-shaped rod 1 is arranged on the base 31; the movable plate 32 is movably disposed on the base 31.

Specifically, the movable plate 31 is engaged with the base 31 to clamp the cross arm steel material.

Further, the movable plate 32 is provided with a plurality of connection bolts 33 for better fixed connection with the cross arm steel.
