Description

[0002] In the new transmission line, single section often has one time crossing many railways, highways and power lines, which needs very high safety and reliability, and the damage of main structure in crossing process can make the crossed facilities system not work normally, and at the same time, the crossing construction time and cost need to be reduced as much as possible, therefore, the operation mode, operation time limit and construction safety of crossing stringing construction need to meet higher requirements. The traditional crossing construction method is to set up crossing frame and net structure above the crossed facilities by using bamboo, steel pipe and other materials to meet the safe operation of the crossed facilities during stringing construction, but due to the inherent limitation of these traditional crossing frames, they cannot well adapt to the new situation of crossing construction, for example, the bamboo crossing frame occupies large area, has high requirement on terrain and environment, and needs long setting time, and the steel pipe crossing frame has heavy quality, large transportation quantity and long installation and removal time, and all of them are only suitable for low voltage grade power line crossing. When the distance between the crossed facilities and the ground is high, many rows of crossing frames need to be set up on both sides of the crossed facilities, and a large amount of manpower and material resources need to be invested to complete the crossing construction task. In this case, it is very necessary to design a special crossing frame suitable for rapid stringing construction of transmission line.
