Abstract

The invention relates to the field of electric power, and especially relates to an insulator replacement assisting fixture. The fixture comprises a left limiting member and a right limiting member. The left limiting member includes a semi-circular clamping part, the two sides of the clamping part extend outward to form fixing parts, and the end of each fixing part is provided with a fixing hole. The right limiting member is arranged symmetrical with the left limiting member. By using the scheme, assembly and disassembly are flexible and efficient.

Description

An auxiliary fixture for replacing insulators

technical field

The invention relates to the field of electric power, in particular to an auxiliary clamp for replacing insulators.

Background technique

Transmission line maintenance operations are high-altitude operations that require climbing towers, and the replacement of line insulators accounts for the largest proportion of maintenance operations. In the operation process of replacing insulators, the lifting and transfer of insulators are indispensable and important links in the operation process.

The traditional (glass) insulator replacement operation method is: bind the insulators with ropes on the ground, pass them to the cross arm of the iron tower through the ropes, and the high-altitude workers untie the ropes at high altitude, and then install the insulators.

But the above method has the following problems:

The knots are inconsistent, and it takes time and effort to dismantle the ropes;

The rope binding is not firm, and the (glass) insulator may fall off;

(Glass) insulators are prone to damage during lifting.

Therefore, the inventor made further research on this, and developed an auxiliary clamp for replacing insulators, and this case arose from this.

Contents of the invention

The object of the present invention is to provide an auxiliary fixture for replacing insulators, which is flexible in assembly and disassembly and high in efficiency.

In order to achieve the above object, the technical scheme of the present invention is as follows:

An auxiliary fixture for replacing insulators, including a left limiter and a right limiter, the left limiter includes a semi-circular clamping part, the two sides of the clamping part extend outward to form a fixed part, and the fixed part A fixing hole is opened at the end, and the right limiter and the left limiter are arranged symmetrically.

Further, the fixing holes of the fixing part of the left limiting part and the fixing part of the right limiting part can overlap together.

Further, the fixing holes of the left limiter and the right limiter can be fixed by bolts, and pull rings are arranged on the bolts.

After adopting the above scheme, the present invention has the following advantages compared with the prior art:

The insulator string can be lifted vertically, and the phenomenon of the insulator string colliding with the tower during the lifting process is significantly reduced, reducing the possibility of damage caused by the insulator string colliding with the tower; avoiding the situation of finding a knot, directly unscrew the screw to loosen the insulator string, which greatly reduces the time for understanding the rope; reduces the binding time, and will not cause the insulator string to fall off due to loose binding of the insulating rope.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, an auxiliary fixture for replacing an insulator includes a left limiter 1 and a right limiter 2. The left limiter 1 and the right limiter 2 are symmetrical in structure, and both include a semicircular clamping part 3. Both sides of the clamping part 3 extend outward to form a fixed part 4, and the end of the fixed part 4 is provided with a fixed hole 5, and the fixed part 4 of the left limiter 1 and the fixed hole 5 of the fixed part 4 of the right limiter 2 can Overlap together, by passing through the bolt 6 in the fixing hole 5, the left limiter 1 and the right limiter 2 can be fixed together, and the semicircular clamping part 3 of the two forms a circular hole, and the circular hole For engaging the insulator, a pull ring is provided on the bolt 6 passing through the fixing hole 5, and then the auxiliary fixture can be lifted smoothly through the chain.

The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, any non-substantial changes to the present invention by using this concept should be an act of violating the protection scope of the present invention.
