Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] In this embodiment, the tower body repaired by transmission lines is taken as an example, as Figure 3 to Figure 6 As shown, the transmission line emergency repair tower body provided by the embodiment of the present invention includes: corner post 1, tower body section 2, bolt 3, double-breasted bolt, column body 5, side plate 6, bolt hole 7, and vertical hole 8. When the angle between the side panels 6 of the corner columns 1 is 90°, four corner columns 1 need to be spliced ​​to form the tower body section 2; first, the side panels 6 of the two corner columns 1 without bolt holes 7 are respectively connected by welding to form Two modular units are integrally formed, and secondly, the two modular units are joined together and fastened with double-breasted bolts in the bolt holes 7 of the double-breasted structur...

Abstract

The invention provides a transmission line urgent repair tower body which is formed by connecting modularized tower body sections end to end. Each tower body section is formed by splicing corner posts. The transmission line urgent repair tower body is characterized in that each corner post comprises two side boards, wherein an included angle is formed by the two side boards with a post body serving as an axis, bolt holes perpendicular to the post body are formed in the edge of one side board at intervals, and the bolt holes are used for connection between the corner posts. Compared with the prior art, the transmission line urgent repair tower body has the advantages that light weight and modularization are guaranteed, meanwhile the geometric dimension of an urgent repair tower is remarkably increased, the carrying capacity of the urgent repair tower is remarkably improved, the application range is obviously increased, and an effective way is provided for urgent repair of large-load and large-size structures with ultrahigh voltage and the like.

Description

technical field [0001] The invention relates to a tower body for a power transmission line, in particular to a power transmission line emergency repair tower body. Background technique [0002] Electricity is an important energy source related to the national economy and people's livelihood, and it has the characteristics of instant. Once the transmission line is damaged and the transmission is interrupted, it will cause huge economic losses and serious social impact. Once the permanent tower of the transmission line is damaged, immediately use the emergency repair tower to support the transmission line, resume power transmission as soon as possible, and gain time for the reconstruction of the permanent transmission tower. As emergency repair equipment, it needs to deal with various complex terrains, including mountains, deserts, plains, hills, etc., especially high mountains and other terrains. At this time, large machinery and equipment cannot be reached and can only be tr...
