Embodiment Construction

[0026] This specific embodiment adopts following technical scheme: it comprises the following steps:

[0027] 1. Analysis: Concrete sleepers have been installed more than 10 years ago under any curves greater than 4° on the track; most of the passing trains are coal vehicles or empty vehicles, plus some grain vehicles and passenger-cargo mixed trains . The annual tonnage exceeds 60mgt. All coal trucks are arranged on other lines, which only allow empty coal cars to pass.

[0028] 2. Most of the most serious wear and loss to concrete sleepers is formed during the passage of fully loaded coal trains.

[0029] 3. The rail Cant data obtained by the reference inspection vehicle is used to locate the area with a high Cant (Cant is greater than 2°).

[0030] 4. Engineers thoroughly inspected these sections and selected 22 of them for testing and comparison of the detection system. These sections contain damaged backing plates, insulators and other track components or are about to...

Abstract

The invention discloses a rail wheel tread wear degree detection method, and belongs to the technical field of rail detection. According to the present invention, analysis is performed, wherein concrete crossties are arranged under the bending paths having the bending angle of more than 4 DEG on the rail before more than 10 years, and most of trains are coal conveying trains or empty trains, and a plurality of grain conveying trains and passenger and freight mixed trains; worn pad plates, damaged or frayed insulation bodies, loose fasteners, cast and loose supporting materials, excessive rail wear, and broken crossties are detected; the goal is to evaluate the data of the existing track inspection car (TGC) and whether other detection system technologies can locate the position of the RSA; the purpose is to determine whether the output data of the TGC can be used for detect the RSA; and with the rail wheel tread wear degree detection method, the defect misjudgement rate and the miss of detection can be effectively reduced, the position, the size and the depth of the rail wheel tread defect can be exactly detected, and the rapid and effective new approach with the characteristics of low cost and high detection precision is provided for the rail wheel tread wear degree surface defect detection.

Description

technical field [0001] The invention relates to the technical field of rail detection, in particular to a detection method for the wear degree of a rail tread. Background technique: [0002] In my country's transportation industry, railway transportation plays an irreplaceable role. [0003] Rail transport is a mode of land transport in which trains are guided on two parallel rails. Rail transport is one of the most efficient known forms of land transportation. The rails provide an extremely smooth and rigid medium on which the train's wheels roll with minimal friction. This way, people on board the train feel more comfortable and save energy. If properly configured, rail transport can save 50 to 70 percent of energy compared to road transport for the same weight of passenger and cargo. Moreover, the rails can evenly distribute the weight of the train, which greatly increases the load capacity of the train. [0004] In order to ensure the safety and speed of railway tra...
