Embodiment Construction

[0026] In order to better understand the present invention, the invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0027] By standardizing and summarizing the use method and technical means of the road spanning frame, the inventor has developed a new type of road spanning device for power grid construction, which is very necessary to improve the safety and efficiency of power transmission line spanning construction. The road crossing device for power grid construction of the present invention adopts new insulating materials and structures, which can not only avoid the phenomenon of temporarily cutting down moso bamboo and trees around the line during crossing construction, but also avoid the traditional steel frame structure being too bulky and difficult to transport and construct. features.

[0028] For details, please refer to figure 1 and figure 2 , The road spanning device for power network construction of ...

Abstract

The invention discloses a road crossing device for power grid construction. The road crossing device comprises vertical insulating members, vertical supporting members, an insulating crossbeam and wire passing wheels. Each side of the road crossing device comprises at least one vertical insulating member which is vertically overlapped and supported on the corresponding vertical supporting member. The tops of the vertical insulating members on two sides are connected through the insulating crossbeam. The wire passing wheels are mounted at the top of the insulating crossbeam. The vertical insulating members and the insulating crossbeam are formed by assembly of fiberglass epoxy resin tubes filled with foam inside. The vertical insulating members and the insulating crossbeam are formed by assembly of the fiberglass epoxy resin tubes filled with the foam inside, so that the defects of conventional materials such as moso bamboos, China firs and steel tubes in current crossing construction are overcome; new portable high-strength insulating materials are adopted, the weight is reduced to the greatest extent on the condition that strength requirements are met, and accordingly, transporting and mounting under bad conditions are facilitated.

Description

【Technical field】 [0001] The invention relates to the field of power transmission and transformation grid construction, in particular to a road crossing device for grid construction. 【Background technique】 [0002] In the construction of live spanning wiring, in order to make the ground wire pass through the spanned object safely, it is necessary to build a temporary spanning frame or cableway. The safety and reliability of spanning frame or cableway is one of the important factors affecting the safety and economy of wire erection construction. [0003] At present, the typical spanning frames in China can be divided into materials, mainly bamboo spanning frames, wooden spanning frames, steel pipe spanning frames, aluminum alloy spanning frames, etc. The quality of the span depends largely on the quality of the materials used to make up the span. The moso bamboo on which the frame is built is prone to defects such as insects and cracks, and the fir poles used in the wooden ...
