Detachable movable crossing frame

Technical Field

The utility model relates to a crossing structure technical field specifically is a dismantled and assembled portable crossing structure.

Background

The crossing frame is a facility for enabling current leads to safely and smoothly pass through in circuit construction. In the construction of the power transmission line, various obstacles such as crossing roads, railways, broadcasting lines, power lines and the like are often encountered, and in order to prevent the lead from being damaged and not influence the safe operation of the crossed objects, crossing frames are erected at the crossed positions before paying off so that the lead can safely and smoothly pass through.

Due to the influence of landforms, landforms and line channels, the phenomena of crossing houses, highways, railways, wharfs, bridges, running lines and the like in construction sites are increasing. Meanwhile, when line defects are processed and power transmission lines cross distribution lines to conduct lead frame facility working hours, the crossed distribution lines are often subjected to power failure processing, inconvenience is brought to production and life of customers, and the distribution network power supply reliability of enterprises is directly affected. In order to ensure the reliability of power supply, a common method is to overlap a crossing frame on a lower-layer operating line of a construction line, so that the existing line is protected without power failure during line construction.
