Embodiment Construction

[0084] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0085] The present invention provides a method for assessing the state of use of a common-speed line rail, which is specifically implemented through the following steps:

[0086] Step 1: Divide the measurement interval according to the different jurisdictions of each public works section and the total annual traffic volume.

[0087] During the division process, it is necessary to weigh the total annual rail throughput and the responsible areas of different public works sections, and divide the rails with the same or similar annual total throughput (with a difference of 10Mt) within the jurisdiction of the same public works section into one section. For example, according to different jurisdictions, it is divided into Xuzhou, Bengbu, Nanjing and Shanghai public works sections, and according to the traffic volume, the jurisdiction of Xuzhou public works section...

Abstract

The invention discloses a general speed line steel rail use state evaluation method, which comprises the following steps of: firstly, dividing a measurement interval according to different jurisdiction areas of various work sections and annual total passing amount, collecting steel rail information in the interval, and determining a measurement mileage according to the steel rail information; then, conducting steel rail detection, and obtaining steel rail information parameters including steel rail profile GQI, abrasion loss, light band width and position, disease conditions and damage results; evaluating the use state of the steel rail according to the detected information parameters of the steel rail, the total passing amount of the steel rail and the total passing amount after recent polishing; scoring according to the basic parameters of the steel rail state; deducting scores according to the result of the disease; and finally giving the total score of the steel rail, and guiding the polishing of the steel rail according to the rating state. According to the general speed line steel rail use state evaluation method, all indexes of the steel rail are comprehensively considered,and steel rail data information is obtained through measurement, and the steel rail is subjected to refined scoring and rating, steel rail polishing plan arrangement is optimized according to rating information, and the resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of railway line engineering, and relates to a method for assessing the use state of steel rails on common-speed lines. Background technique [0002] The purpose of rail grinding is to solve the problem of rail surface disease, optimize the profile of the rail, improve the contact relationship between the wheel and the rail, and prolong the service life of the rail. At present, the rail grinding of ordinary speed lines is mainly "periodical", that is, the grinding plan is arranged according to the rail grinding maintenance cycle guidance, and the status investigation, design and implementation of the rails are carried out after the grinding range is determined. But "periodic" grinding has the following problems: [0003] (1) The grinding volume is large, and the operation capacity of the grinding vehicle is limited. [0004] China Railway Shanghai Bureau Group Co., Ltd. has more than 6,000 kilometers of mai...
