Abstract

The invention discloses a cross-over device for live operation of a power transmission line. By setting a cross-type lifting mechanism and a folding mechanism, the driving component drives the folding mechanism to push the cross-type lifting mechanism to perform fast lifting and folding. The lifting height range is large and the applicability Strong, can adapt to work under strong wind conditions, effectively reduce labor costs, and is convenient for transportation, installation and disassembly, high installation and disassembly efficiency, effectively shortening the construction period, and the disassembled cross-type lifting mechanism can be used for secondary use; at the same time, By setting up multiple symmetrical cross-type lifting mechanisms and achieving balanced support for the device through the horizontal adjustment device, the problem of the overall device being tilted due to the uneven road surface is effectively reduced, and the safety during the construction process is improved; In addition, By setting the spanning bar and setting the guide rail on the spanning bar, the automatic construction of the protective net is realized, and there is no need to manually pull the net to cross the high-voltage cable, which greatly improves the efficiency of the protective net construction.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to a crossover device for live operation of a power transmission line. Background technique [0002] In power grid power transmission and transformation projects, it is often necessary to carry out construction across transmission lines, highways, etc. In order to ensure the power supply reliability of the crossed power lines, live crossing construction schemes are usually adopted. In order to ensure the safe distance between the new transmission line or maintenance line and the object to be spanned, it is necessary to build an insulation net or a spanning frame between the two in advance. [0003] The traditional spanning frame needs to invest a lot of manpower to climb and build. There are no relevant intelligent safety measures in the construction process to carry out standardized operations for the construction and disassembly process. The single-use assem...
