Description

Vertical crossing frame mast

Technical Field

The utility model relates to the technical field of vertical crossing frames, in particular to a vertical crossing frame mast.

Background

With the increasing of the scale of the power network system, the power transmission lines with ultra-high voltage and ultra-long span are rapidly increased, and the scope of influence of the development of the power transmission lines crossing the new construction technology on the economic and social development is wider. In the construction process of crossing and erecting a newly built power transmission line, along with increasing voltage level, the number of operated power grids, rails, railways, viaducts and other obstacles which the ultra-high voltage power transmission line needs to cross is increased, and particularly, the power outage operation is more and more difficult due to the attachment of the modern industry to the power, particularly, the construction of high-grade line power outage is carried out, the construction progress and the construction cost of crossing and erecting the line engineering are seriously influenced, and meanwhile, a certain loss is brought to social life production. Therefore, when a condition of crossing a plurality of railways, highways and power lines at a time in a single gear occurs in a newly built power transmission line, extremely high safety and reliability are required, meanwhile, crossing construction time and cost are reduced as much as possible, and the operation mode, operation time limit and construction safety of crossing construction need to meet higher requirements. The traditional spanning construction method utilizes bamboo, steel pipes and other materials to build a spanning frame and a net sealing structure above the spanned facilities so as to meet the requirement that the spanned facilities can safely run during the overhead construction, but the inherent limitations of the traditional spanning frames cannot be well suitable for new situations of spanning construction, such as large occupied area of the bamboo spanning frame, high requirements on the environment of terrains and landforms and long erection time, while the steel pipe type spanning frame has heavy weight and large transportation capacity, and long installation and dismantling time and is only suitable for spanning the electric power lines with low voltage level. When the distance between the straddled objects is relatively high, a plurality of rows of straddling frames are erected on two sides of the straddled objects, a great amount of manpower and material resources are needed to be input, the straddling construction task can be completed, and safety accidents endangering personal risks easily occur. In this case, it is necessary to design a special crossing frame suitable for rapid wiring construction of the transmission line. Thus, the method meets the requirements of full life cycle construction, can further improve engineering construction quality and efficiency, and improves economic, environmental and social benefits.
