Embodiment Construction

[0016] The technical solution of the present invention will be described in further detail below with reference to the accompanying drawings. Such as figure 1 As shown, the tower type is a double-circuit linear tower, including a tower head, a tower body 6 and a tower leg 7 . The tower head is composed of a ground wire support 1, an upper cross arm 2, a middle cross arm 3, a lower cross arm 4 and a middle column 5 of the tower body. The ground wire support 1 is installed at the ends of both sides of the upper cross arm 2; the upper cross arm 2, the middle cross arm 3 and the lower cross arm 4 arranged from top to bottom are respectively connected with the middle column 5 of the tower body, and are vertically symmetrical to the tower 5 pillars in the body. The whole tower is composed of a tower head, a tower body 6 and a tower leg 7, and the tower head and the tower body 6 are connected by a steel pipe variable angle steel transition node 8.

Abstract

The invention relates to a steel pipe and angle iron hybrid ultrahigh-voltage power transmission tower. The power transmission tower is shaped like a double-loop straight tower, and comprises a tower head, a tower body (6) and tower legs (7), which are sequentially connected; the tower head comprises earth wire supports (1), an upper crossarm (2), a middle crossarm (3), a lower crossarm (4) and a tower body column (5), wherein the upper crossarm (2), the middle crossarm (3) and the lower crossarm (4) are arranged from top to bottom, and are perpendicular to the tower body column (5) and symmetrical with the tower body column (5) as an axis, and the earth wire supports (1) are mounted on the end parts of both sides of the upper crossarm (2); the tower head is connected with the tower body (6) through steel pipe-to-angle iron transitional nodes (8); the tower head is made of angle iron members; and the tower body (6) and the tower legs (7) are made of steel pipe members. The invention has the advantages that not only can the bearing capacity of the original steel pipe tower body be kept unchanged, but also the usage of steel pipes is reduced, and the current problem of severe shortage in the capability of producing steel pipes for power transmission line construction in China can be effectively mitigated.

Description

technical field [0001] The application belongs to the field of power transmission line equipment, in particular to a new type of steel pipe used in power transmission lines—an angle steel hybrid tower. Background technique [0002] With the construction of my country's UHV power grid and the popularization of multi-circuit technology for transmission lines on the same tower, the trend of iron towers developing towards large loads and large sizes is becoming more and more obvious, which makes the advantages of steel pipe tower applications more and more aroused people's attention. Compared with the angle steel tower, the wind resistance effect of steel pipe tower components is small, the section rigidity is large, the iron tower components are few, the force transmission is clear, and the structure is reliable, which is conducive to enhancing the ability of the structure to resist natural disasters under extreme conditions, and can save steel and foundation concrete. Better s...
