Problems solved by technology

[0003] At present, the early construction units of power transmission lines have accumulated a variety of cross-blocking technologies. The earliest method was to use moso bamboo towers to block the network, but this method has low safety and reliability; Solved the difficulty of spanning construction, however, the working time of network closure is longer
Moreover, the spanning frame of the moso bamboo guide rail lifting system and the spanning frame of the steel pipe guide rail lifting system are difficult to build, and the span frame of the guide rail lifting system occupies a large area, and there are problems of temporary land requisition and compensation for young crops

Abstract

The invention discloses a crossing frame with a guide rail lifting system and relates to the technical field of power grid construction. The solved problem is to provide the crossing frame which is high in safety and reliability, rapid in grid closure, economical and reasonable. According to the mainly adopted technical scheme, the crossing frame with the guide rail lifting system comprises a crossing frame body and the guide rail lifting system. The guide rail lifting system comprises a guide rail and a lifting structure. The guide rail is arranged on the crossing frame body. The lifting structure is movably connected with the guide rail and can move along the guide rail. The guide rail lifting system is used for driving a grid closure structure to move along the crossing frame body.

Description

technical field [0001] The invention relates to the technical field of power grid construction, in particular to a spanning frame with a guide rail lifting system. Background technique [0002] With the rapid development of the economy, the power construction in various places is developing rapidly. More and more power lines span highways, high-speed railways, etc. Since the crossed expressway or high-speed railway is running with electricity, the long-term network closure will make the work with related units more cumbersome, affecting the normal operation period. Therefore, how to build the spanning frame of the guide rail lifting system in a short time to ensure that the construction of the power transmission line can be carried out safely and efficiently. [0003] At present, the early construction units of power transmission lines have accumulated a variety of cross-blocking technologies. The earliest method was to use moso bamboo towers to block the network, but this...
