The connecting plate is ground-fixed so that it is evenly stressed without deformation and damage, so as to achieve the purpose of quickly tightening the insulator string, greatly improving the work efficiency and ensuring the smooth and safe completion of the operation.

Description

LF type connecting plate fixing fixture for tension pole and tower wire end

technical field

The utility model relates to a fixing tool used when replacing tension pole tower insulators on a 220kV transmission line, specifically an LF-type connecting plate fixing fixture at the wire end of a tension pole tower.

Background technique

With the development of the power grid, a number of compact lines and double-circuit lines on the same tower have been put into operation one after another. In order to ensure the safe and reliable operation of transmission lines and improve the reliability of power supply, the importance of line maintenance is becoming more and more prominent, and the amount of maintenance will increase with the increase of line length. Replacing the insulator strings of tension towers on 220kV lines is a complex and important work item in the operation. The connection between the double-split conductors and the insulators is mostly LF-type (back-shaped) connecting plates with double hanging points. When replacing the entire string of insulators, Since no force is allowed in the middle of the connecting plate, there is no effective fixing point, and the LF type (back-shaped) connecting plate cannot be effectively connected with the tightening tool; when the connecting plate is fixed with general clamps, the stressed part is in the middle part , the strength of the connecting plate cannot meet the force requirements of the tightening tool on the connecting plate; if the general operation process is used, the construction intensity is high and the tools are cumbersome, which makes the operation project unable to be carried out quickly and smoothly.

Contents of the invention

The purpose of this utility model is to solve the problem of effective connection between the tightening tool and the LF type (back-shaped) connecting plate when replacing the tension insulator, and provide a simple structure, low cost, easy installation and convenient construction for use on 220kV transmission lines. Convenient, safe and reliable LF-type connecting plate fixing fixture for the wire end of the tension pole tower.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the LF type connecting plate fixing fixture at the wire end of the tension pole tower is characterized in that: it is composed of a V-shaped fixture plate and a hook, and the V-shaped fixture plate The two ends of the front end of the body are symmetrically fixed with hooks, and the rear end of the V-shaped fixture plate is provided with connecting holes.

The length of the V-shaped fixture plate is 360mm, the thickness is 25mm, the width of the hook is 23mm, the horizontal width between the outer edges of the two hooks is 340mm, and the diameter of the connecting hole is 24mm.

The utility model has the beneficial effects of simple structure, low cost, and convenient construction. When replacing LF-type (back-shaped) connecting plate insulator strings during a 220kV line power failure, the connecting plate can be fixed easily, effectively, quickly and safely, so that It is evenly stressed without deformation and damage, and achieves the purpose of quickly tightening the insulator string, greatly improving work efficiency and ensuring smooth and safe completion of operations.

Detailed ways

Make the utility model with reference to accompanying drawing 1, Fig. 2. The LF-type connecting plate fixing fixture for the wire end of the tension pole tower is characterized in that it is composed of a V-shaped fixture plate body 1 and a hook 2, and is symmetrically fixed on the two ends of the front end of the V-shaped fixture plate body 1. The hook 2 is provided with a connecting hole 3 at the rear end of the V-shaped clamp body 1 .

The V-shaped jig body 1 and the hook 2 are made of a single piece of aluminum-magnesium alloy.

The length of the V-shaped clamp body 1 is 360mm, the thickness is 25mm, the width of the hook 2 is 23mm, the horizontal width between the outer edges of the two hooks 2 is 340mm, and the diameter of the connecting hole 3 is 24mm.

When the utility model is used to replace the tension insulator string, the strength and tension of the V-shaped fixture plate 1 and the hook 2 should meet 15T, so that it can meet the tightening load requirements like the tightening tool; the two hooks 2 are respectively It is stuck on the inner side of the side hanging point of the LF-type connecting plate wire. The connection hole 3 is connected with the double hook and other tightening tools through a special pull rod such as a U-shaped ring or an extension ring. According to the technology, the wire tightening tool is fixed on the pole tower. When the wire tightening tool is tightened, it will drive the V-shaped jig body 1 to move, so that the hook 2 moves with the LF-type connecting plate to achieve the purpose of tightening the wire, and finally make the durable The string of insulators is loosened, and the single piece or the whole string of insulators is replaced, thereby reducing the working time, reducing the labor intensity of the operators, and ensuring the smooth and safe completion of the work.
