Problems solved by technology

[0003] Traditional double-circuit transmission towers usually use a drum-shaped tower head or an umbrella-shaped tower head. The wires are arranged vertically from top to bottom, making the height of the tower head part higher. When the transmission tower passes through the section that requires tower height, Even if the height of the tower is reduced to the minimum, it still cannot meet the requirements of use

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0024] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "secured" to another element, it may be detachably or non-detachably fastened thereto. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expression...

Abstract

The invention discloses a double-circuit cat head tower and its tower head structure. The tower head structure includes: a first wire cross arm that can expand and contract along its length direction; and a curved arm assembly, which includes a first curved arm and a The second curved arm, one end of the first curved arm is connected to one end of the first wire cross-arm, and one end of the second curved arm is connected to the other end of the first wire cross-arm; the other end of the first curved arm can be opposite to the second curved arm The other end of the arm is rotatably connected so that the first wire cross arm can translate up and down, and the crank arm assembly also includes a first locking mechanism for locking the relative rotational movement of the first crank arm and the second crank arm, or the first crank arm It can be stretched along its length direction and the second crank arm can be stretched along its length direction, so that the first wire cross arm can translate up and down. Movement's second locking mechanism. In the double-circuit cat head tower and its tower head structure of the present invention, the height of the tower head can adapt to different erection requirements.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a double-circuit cat head tower and its tower head structure. Background technique [0002] With the further strengthening of my country's economic strength, the demand for electricity has also become larger and larger, making the line corridors increasingly complex, and subsequently put forward higher-level requirements for the erection of transmission towers, especially in the interconnection between lines. When the line construction is carried out in the intersection area, the height requirements for the pole tower become more stringent. [0003] Traditional double-circuit transmission towers usually use a drum-shaped tower head or an umbrella-shaped tower head. The wires are arranged vertically from top to bottom, making the height of the tower head part higher. When the transmission tower passes through the section that requires tower height, Even if the height of...
