A device that spans the network

Abstract

The invention discloses a crossing block device and relates to the technical field of power grid construction. The problem to be solved is to provide the crossing block device which is high in safe reliability, practicable in technology, convenient in construction, economic and reasonable. According to the main technical scheme, the crossing block device comprises a first block system and a second block system which is mirror symmetrical with the first block system, wherein the first block system is at a preset distance from the second block system; and the first block system comprises: a guide rail lifting structure is arranged on a crossing frame and can move along the crossing frame, the first end of a block structure is rotatably connected with the guide rail lifting structure, the block structure is used for being driven by the guide rail lifting structure to move along the crossing frame, a retractable structure is connected with the crossing frame and the second end of the block structure separately, and the retractable structure is used for being in a stretching state when the block structure moves along with the crossing frame to the preset position to enable the block structure to unfold relative to the crossing frame.

Description

technical field [0001] The invention relates to the technical field of power grid construction, in particular to a cross-network sealing device. 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 a spanning network sealing device in a short time to ensure that the construction of power transmission lines 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 method has low safety and reliability; ...

AI Technical Summary

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, it is difficult to build the bamboo cross-sealing device and the steel pipe cross-sealing device. The construction of the cross-sealing device occupies a large area and there are problems of temporary land requisition and compensation for young crops.
