Embodiment Construction

[0016] The factory manufacturing method of the elastic hanging string of the railway catenary is characterized in that: according to the plane elevation, coordinate calculation, and wrist arm support structure calculation, the position mileage of the positioning point of the catenary, the relative span between the pillars or the positioning points, and the rail surface of each point are obtained. Elevation and catenary cable, contact line elevation, and then through the establishment of a mathematical model to analyze the force of each positioning point, and finally obtain the number of suspension strings installed between each positioning point and the length data of the position. After the adjustment of the suspension string is completed, the positioning Point on-site measurement and then calculate, preset several spans and then carry out on-site installation measurement, correct the calculation parameters of the hanging string according to the on-site measurement situation, u...

Abstract

The invention discloses a method for industrially manufacturing elastic railway catenary droppers. The method includes outputting the position and length of a suspension point of a coupler by means of combining graphs and data, firstly, performing plane-elevation data calculation and catenary supporting structure data calculation, and setting experimental parameters in catenary dropper calculation; performing calculation software modeling to an elastic catenary dropper; developing calculation software of the elastic catenary dropper; and outputting the length and related data of the dropper through the software. By the method, the length and the related data of the elastic dropper can be calculated, industrial manufacturing of the catenary dropper can be realized, and during construction, the dropper can be mounted in place at one step, so that mounting accuracy and mounting speed are improved.

Description

technical field [0001] The invention relates to the field of production methods for railway catenary elastic suspension strings, in particular to a factory-based manufacturing method for railway catenary elastic suspension strings. 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. Developed the application software for calculation of elastic chain-type suspension hanging strings, input the data measured on site, calculated the size of each hanging string of each anchor section, pre-configured in factory in advance, and successfully installed on site at one time, saving a lot of adjustment man-hours. The calculation method calculates the length of the catenary elastic suspension string based on the calculation data of the pla...
