Embodiment Construction

[0020] The railway catenary support structure customization method includes the following steps:

[0021] (1) According to the plane elevation model, coordinate system, catenary pillar distribution and catenary plane layout, use the trigonometric function relationship to analyze and calculate, and obtain the base elevation of the catenary positioning point pillar position, and calculate and draw according to the supporting structure installation diagram The catenary cable and contact line position elevation, fully consider the influence of ambient temperature, linear expansion coefficient, compensation type, center anchor position on the wrist arm and positioning offset, summarize the advantages of elastic chain suspension installation stability, and establish elastic chain type Suspension support structure model;

[0022] (2) Through the elastic chain suspension support structure model, develop software, calculate the theoretical value of the support structure through the sof...

Abstract

The invention discloses a railway contact net support structure customization method, which comprises the following steps of firstly carrying out plane-elevation calculation data calculation; then, carrying out contact net support structure theoretical data calculation; carrying out contact net support data field measurement; carrying out contact net support calculation software modeling; carrying out contact net support structure calculation software development; and finally carrying out software output data field verification. According to the software disclosed by the railway contact net support structure customization method, configuration data, such as a flat cantilever, an inclined cantilever and a brace can be calculated, the flat cantilever, the inclined cantilever and the brace can be installed to the proper position at a time, and the installation precision and speed can be improved.

Description

technical field [0001] The invention relates to the field of catenary customization methods, in particular to a method for customizing a railway catenary support structure. Background technique [0002] With the continuous development of high-speed railways, the construction of catenary elastic chain type suspension strings is very difficult, and the adjustment of the length of suspension strings is cumbersome, which consumes a lot of manpower, material resources and time. The application software for calculation of elastic chain-type suspension hanging strings has been developed, which can input the data measured on site, calculate the size of each hanging string of each anchor section, pre-configure in advance in factory, and install successfully on site at one time, saving a lot of adjustment man-hours. The accuracy of the calculation of the elastic suspension string depends on the accuracy of the flat arm, inclined arm and support structure data. This support structure c...
