Seamless track intelligent construction method

Abstract

The invention discloses a seamless track intelligent construction method, which comprises the following steps of: comprehensively and automatically acquiring relevant parameters of a paved track and design technical data of an on-site paved track and a lower section unit track through a software system, analyzing by a computer to obtain an optimal locking track temperature, and calculating an optimal stretching amount of a steel rail according to an operation track temperature acquired on site, thereby guiding seamless track construction and realizing remote monitoring. The method comprises the following steps: S1, designing a software system; S2, transforming hydraulic steel rail stretching equipment; S3, designing a control system; and S4, designing an intelligent cloud stretching dynamic monitoring system. According to the method, the problem that the design of the locking rail temperature is mainly considered in the current manual field calculation and is difficult to realize is avoided; and double control over the steel rail stretching amount and the pressure gauge is achieved, the problems of unit rail joint length errors and the like can be found in time, and operation quality is ensured. Data can be transmitted to a background in time, remote monitoring of progress and quality is achieved, data is prevented from being tampered manually, and hidden dangers caused by manual measurement, recording, stretch value input and the like are prevented from being covered.

Description

technical field [0001] The invention relates to the technical field of seamless line construction methods, in particular to an intelligent construction method for seamless lines. Background technique [0002] The "Quality Acceptance Standards for Railway Track Engineering Construction" stipulates that the locked rail temperature of seamless lines has the following requirements: it must be within the design locked rail temperature range, the difference between the left and right strands of rail locked rail temperature shall not be greater than 5°C, and the adjacent unit rail locked rail The temperature difference shall not be greater than 5°C, and the temperature difference between the maximum and minimum locking rails in the same section shall not be greater than 10°C. [0003] Based on the data collected on the locked rail temperature of the five lines opened in recent years, it was found that the locked rail temperature did not meet the acceptance criteria, and some lines ...

AI Technical Summary

Problems solved by technology

The reasons are analyzed: First, the locked rail temperature of the track to be laid is determined manually. When determining the optimal locked rail temperature of the track to be laid, the actual locked rail temperature of the adjacent and opposite side rails of the upper section and the design locked rail temperature of the track to be laid are considered. The design rail temperature of the adjacent rail, the locked highest and the lowest locked rail temperature in this section are less considered; second, when the difference between the actual stretching amount and the calculated stretching amount is small, it is not calculated separately, and the locking is guessed, which is prone to the locked rail temperature of the track to be laid. The temperature of the locked track is lower than the lower limit of the design; the third is that the locked rail temperature of the adjacent rail section and the opposite side rail section is affected by the error of copying, which affects the determination of the locked track temperature of the track to be laid; the fourth is that the on-site data is manually entered into the computer, which may artificially cause the lock Rail temperature does not meet the requirements

Because only a single index of stretching is controlled, when the unit rail length is wrong, the locking rail temperature will be seriously unqualified, increasing the workload of daily maintenance, and even directly threatening the safety of driving
