Description

Novel general triple tension end clamp

Technical Field

The utility model relates to a warning fence technical field especially relates to a novel general trigeminy strain tip card.

Background

The insulator is an important component of the extra-high voltage overhead transmission line. Under the action of long-term electromechanical load and the influence of various climatic environments, the insulator is degraded into a zero-value insulator or a low-value insulator, and the zero-value insulator must be replaced in time in order to ensure the safety of equipment. In recent years, the replacement work of low-zero-value insulators becomes one of the main work of line maintenance, a matched auxiliary tool is required for replacing the insulators, the three-link tension string for a Xianju pumped storage power station-Danxi 500kV double-circuit power transmission line, a wire end hardware fitting comprises a link plate LS3-849060S, a socket hanging plate W-32AH, a parallel hanging plate P-42ST and the like, and the insulators are 300KN suspension insulators. At present, when the insulator at the end of a wire is replaced, firstly, the side string is generally buckled with a screw head and a nut of a socket head hanging plate by a turning plate. And the Xian pumped storage power station-Danxi 500kV double-circuit transmission line, because the distance between the bowl head hanging plate W-32AH and the parallel hanging plate P-42ST is too close, only 150mm, the center distance of the fixture is 480mm, if the turning plate is adopted, one end of the fixture needs to avoid the parallel hanging plate P-42ST, the half of the center distance of the fixture is 240 to 150, so that one end of the fixture needs to detour to avoid the parallel hanging plate P-42ST, thus the two ends of the fixture need to extend towards the direction close to the insulator, firstly, the main body of the fixture is larger and heavier, secondly, the main body of the fixture is too close to the insulator, the installation and operation of the fixture is inconvenient, when the insulator is replaced, the insulator needs to be shaken leftwards and rightwards to touch the main body of the fixture, and the replacement is inconvenient. These problems bring great difficulty to the replacement work of high-altitude operation, bring more risks to the replacement work, and are large in manpower and material resources, time-consuming and labor-consuming.

And a new fixture is generally adopted for clamping two inclined surfaces at the upper end of the link plate LS3-849060S, so that two fixtures are required to be customized when the triple lead end is replaced, and the cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, provide a novel general trigeminy strain end portion card.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a novel general trigeminy strain end portion card, includes the main part, main part one side is provided with the fixture block, it is equipped with connecting screw to insert on the fixture block, connecting screw sets up in the outside one end threaded connection of fixture block in the main part, through connecting screw fixed connection between main part and the fixture block.

In a preferred embodiment, the bottom of the latch is a U-shaped groove.

The technical effect of adopting the further scheme is as follows: the two wings of the main body are arranged at the upper end of the yoke plate LS3-849060S, are far away from the insulator, and are convenient and reliable to operate during replacement.

As a preferred embodiment, the main body is designed in a split structure.

The technical effect of adopting the further scheme is as follows: the structure is split type, the clamping block and the main body are small in size, light in weight and convenient to connect, and the clamping block is replaced to achieve universality.

Compared with the prior art, the utility model has the advantages and positive effects that,

the fixture block and the main body are small in size, light in weight and convenient to connect, the hardware fitting can be inhibited from touching the fixture main body, when the side string and the middle string are replaced, the same main body is used, the fixture block which only needs to be replaced can be universal, the difficulty of replacement operation is reduced, the risk of replacement operation is also reduced, a great deal of manpower, material resources and tools are reduced, the fixture block and the main body are light in weight, small in size and convenient to install, two wings of the main body are arranged at the upper end of a yoke plate LS3-849060S and are far away from an insulator, and the operation is convenient and reliable during replacement.
