Method, device, storage medium and equipment for identifying arched position of track slab

Abstract

The invention provides a method and device for identifying the arching position of a track plate, a storage medium and equipment. The method comprises steps of: acquiring detection data of unevennessof a ballastless track; identifying variation data of unevenness and having arching features of the track plate from the detection data according to set conditions; and determining the arching position of the track plate in the ballastless track according to the identified data. The invention can quickly and effectively identify the arching position of the track plate.

Description

technical field [0001] The present invention relates to the technical field of railway tracks, in particular to a method, device, storage medium and equipment for identifying the arching position of a track slab. Background technique [0002] The ballastless track has the advantages of high smoothness, high durability and small maintenance and repair workload. Ballastless track types mainly include unit slab type, longitudinally connected slab type and double-block type, etc., and the corresponding series include CRTSⅠ type slab type, CRTSⅡ type slab type, double-block ballastless track type and CRTSⅢ type slab type, etc. [0003] CRTSⅡ type slab ballastless track was first used in Beijing-Tianjin intercity and Beijing-Shanghai high-speed railway lines. Its structural feature is that the ends of the unit slabs are connected by longitudinal steel bars, and C55 concrete is poured at the joints of the slabs, so that the unit slabs become longitudinally connected slabs. , so th...

Problems solved by technology

When the track slab is arched and separated from the seam, it can be recognized by the naked eye, which is very inefficient. It is usually difficult to ensure the inspection quality if the inspection line length is guaranteed, and it is difficult to ensure the inspection line length if the inspection quality is guaranteed.

[0008] When the track slab is arched and the separation seam affects the track irregularity, it can be found indirectly by using the comprehensive detection train. However, the track irregularity caused by the track slab arch has the characteristics of small amplitude, small change, and small influence range. Less than the daily maintenance standards of my country's high-speed rail, it is not easy to quantitatively judge

In addition, due to the mileage error caused by the cumulative error of the wheel set, the error of the speed calibration, and the error of the artificial point setting, it is also difficult to judge the detection effect
