Problems solved by technology

In the construction of traditional flexible catenary, the place with the most hard points is the section insulator. The traditional installation method of the section insulator is to install the section insulator directly on the catenary after the whole assembly is completed, and then adjust it. There are many disadvantages such as unequal installation heights of the slideways, uneven arc suppression angles, and non-standard installation tools, which lead to many problems such as excessive installation heights of segmental insulators and unstressed suspension strings. When the locomotive pantograph passes, There will be hidden dangers such as bowing and many hard points, which will endanger the safety of catenary and train operation

Abstract

The invention provides an installation and construction method of a flexible contact network section insulator, and belongs to the technical field of contact network construction methods. The method comprises the following steps: 1, measuring the installation center position of the section insulator, wherein the position is ultrahigh; 2, installing a carrier cable insulating rod; 3, installing thesection insulator; and 4, rechecking and adjusting data. According to the construction method, the construction cost can be reduced, the hidden dangers of arching and many hard spots are eliminated,the construction quality and the construction safety are improved, and the adjustment and maintenance workload is reduced.

Description

technical field [0001] The invention belongs to the technical field of catenary construction methods, and specifically discloses a method for installing and constructing flexible catenary section insulators. Background technique [0002] With the rapid development of high-speed railways, it is particularly important to provide a safe and fast channel for high-speed trains, requiring more and more accurate catenary erection with smaller and smaller errors. In the construction of traditional flexible catenary, the place with the most hard points is the section insulator. The traditional installation method of the section insulator is to install the section insulator directly on the catenary after the whole assembly is completed, and then adjust it. There are many disadvantages such as unequal installation heights of the slideways, uneven arc suppression angles, and non-standard installation tools, which lead to many problems such as excessive installation heights of segmental ...
