Description

Anti-falling net for power transmission construction
Technical Field
The invention relates to the field of power maintenance support, in particular to a falling prevention net for power transmission construction.
Background
In recent years, with the rapid increase of national economy, the power industry develops rapidly, and the rapid development of the transmission line iron tower industry is promoted. According to statistics, the sales income of the transmission line iron tower industry in China is increased from 50 billion yuan in 2003 to 426 billion yuan in 2010, the annual composite growth rate reaches 36.68%, and the industry is in a rapid development period. In 2010, the transmission line iron tower industry in China presents a good development situation, and enterprises in the industry have high management and control capacity on cost and high profit capacity.
Transmission line towers are tower structures used to support and suspend conductors, overhead lines and other accessories, such as high-rise structures that maintain a specified safe distance from conductor to conductor, conductor to tower, conductor to overhead line, conductor to ground or crossover span.
It is generally divided into: wine glass type, cat head type, upper font type, dry font type and barrel type, according to the usage divide into: strain tower, tangent tower, angle tower, transposition tower (changing wire phase position tower), terminal tower and crossing tower.
According to the application of the tower in the transmission line, the tower can be divided into a straight tower, a strain tower, a corner tower, a transposition tower, a crossing tower and a terminal tower. The method comprises the steps that a linear tower and a strain tower are arranged on a straight line section of a line, a corner tower is arranged at a turning position of a power transmission line, higher spanning towers are arranged on two sides of a crossed spanning object respectively, transposition towers are arranged at certain intervals for balancing the impedance of three wires, and a terminal tower is arranged at a connecting position of the power transmission line and a power transformation framework.
The towers used in the transmission line are mainly reinforced concrete poles and iron towers according to the classification of structural materials of the towers. The method is divided into a self-standing tower and a stay wire tower in terms of maintaining the overall stability of the structure. The structure forms of the pole towers are various, and from the established transmission lines in China, the iron towers are frequently used in the transmission lines with the voltage level of more than 110 kV; when the voltage level is less than 66kV, reinforced concrete poles are often used. The tower stay wire is used for balancing the transverse load and the wire tension of the tower, reducing the bending moment at the root of the tower, reducing the consumption of tower materials and reducing the manufacturing cost of a line. On the path of a region with flat terrain, the use of the stay wire tower is common. The type and the shape of the tower are selected according to the voltage grade, the loop number, the topographic condition, the geological condition and the like of the transmission line while meeting the electrical requirements through checking calculation, the tower type suitable for a certain project is selected according to the actual condition, and finally the tower type with advanced technology, economy and reasonability is selected through economic technology comparison.
When transmission line broke down and need the maintenance, need the maintenance workman to climb on the height frame, still need simultaneously ground personnel to connect each other and should cooperate, in order to guarantee high altitude construction's safety, need cooperate anti-falling device during the construction. The anti-falling device for the power transmission line construction is a falling protector with a sliding rail fixed on a tower, and the anti-falling device can only play a role in preventing falling for operating personnel on the tower and can not prevent objects falling from high altitude during operation on the tower, so that certain potential safety hazards exist for the personnel working on the ground in a matched manner.
