Abstract

The utility model relates to an auxiliary device of power construction equipment, and particularly relates to an insulator string fixing traction tool. The insulator string fixing traction tool comprises a triangular yoke plate in a form of isosceles triangle, wherein the top angle end of the triangular yoke plate is fixedly connected with at least two U-shaped rings in series connection; two bottom angle ends of the triangular yoke plate are respectively fixedly connected with a U-shaped ring; two L-shaped plate is fixed at the middle part of the bottom edge of the triangular yoke plate; one side of the L-shaped plate is fixedly connected with the triangular yoke plate, and the other side of the L-shaped plate is vertical to the L-shaped plate; the other sides of the two L-shaped plates are welded and are provided with a via-hole; and a U-shaped hanging ring is mounted in the via-hole. The insulator string fixing traction tool provided by the utility model has the advantages of simple structure and low manufacture cost, and a traction point can be conveniently fixed on the insulator string; and the tensile strength can meet the requirement.

Description

Insulator string fixed traction instrument
Technical field
The utility model relates to the servicing unit of power construction equipment, specifically a kind of insulator string fixed traction instrument.
Background technology
On the 1000kV overhead transmission line during hanging wire, towing point on the insulator string need to be fixed, the structure of not fixing for towing point in the structural shape of existing strain hardware fitting, and often adopt auxiliary Work tool owing to can not bear 10t or above pulling force fully, and have insufficient strength, use unsafe defective.
Summary of the invention
The purpose of this utility model is to solve the technical problem of above-mentioned existence, and a kind of simple in structure, low cost of manufacture is provided, is convenient to the insulator string fixed traction instrument that towing point is fixed, tensile strength meets the demands on the insulator string.
