Description

Technical Field

[0001] The utility model relates to the field of electric power hardware, in particular to an anti-falling bowl head hanging plate. Background Art

[0002] Ball head structure connection fittings and bowl head hanging plate connection are the main ways to install overhead transmission lines, tension suspension string suspension, and insulator connection fittings. In overhead transmission lines, they are used to connect transmission line conductor clamps to towers, and between phase spacer fittings and insulators, playing an important role. It is one of the indispensable corner connection methods for line connection fittings.

[0003] The bowl head hanging plate mainly consists of two parts: bowl head and ball head;

[0004] When the bowl head hanging plate is used at high altitude, there are a lot of corrosive media in the environment where the bowl head hanging plate is located, such as water vapor, flue gas and other chemical gases. The connection position between the bowl head seat and the ball head connecting hardware will be corroded and cause detachment.

[0005] The ball-bowl connection structure is one of the more flexible articulated structures. As long as there is wind, friction will occur between the ball head and the bowl head, causing wear. When the wind speed is high, the frequency of wind action is relatively frequent, and the rotation of the connecting hardware is not flexible, the wear between the ball bowls will be aggravated, and the ball head and the bowl head will easily become detached.

The end of the connecting column away from the ball head assembly is fixed to the mounting ring, and the connecting column is limitedly installed inside the limiting hole by the upper anti-detachment bolt; the ball head assembly is limitedly installed inside the accommodating hole by the lower anti-detachment bolt; the mounting ring is a circular structure made of metal material, and the mounting ring is fixed to the ball head assembly through the connecting column, and the mounting ring is movably arranged inside the accommodating hole.

[0009] Preferably, the connecting seat is a "U"-shaped structure made of metal material, and the cross-section of the bowl head assembly on the top of the connecting seat is a "U"-shaped setting.

[0010] Preferably, the accommodating hole and the limiting hole are connected and arranged in a "T" shape. At the same time, the accommodating hole is intercepted by the lower anti-detachment bolt, and the limiting hole is intercepted by the connecting column.

[0011] Preferably, a first opening and a second opening are respectively provided on the right side wall of the bowl head assembly, and a second screw hole is provided on the inner wall of the limiting hole, while a first screw hole is provided on the inner wall of the accommodating hole.
