Large-resistance three-line gauntleted track railway sleeper for automatically monitoring train state

Abstract

The invention relates to a large-resistance three-line gauntleted track railway sleeper for automatically monitoring train state. The railway sleeper is mainly aiming at the safety problem of patrol personnel and the effect problem of manual patrol. The railway sleeper comprises a fixed sleeper, a moving sleeper and a connecting assembly; the fixed sleeper comprises a long bar, the fixed sleeper is characterized in that a first convex limiting block is arranged at the front end of the long bar, a second convex limiting block and a third convex limiting block are arranged at the rear end of thelong bar, and a connecting groove matched with the first convex limiting block is formed between the second convex limiting block and the third convex limiting block; and a first front connecting shaft is arranged in the first convex limiting block, and rear second connecting shafts are arranged in the second convex limiting block and the third convex limiting block. According to the large-resistance three-line gauntleted track railway sleeper for automatically monitoring the train state, through audio collection and comparison, real-time data are collected to compare audio files and analyzeproblem road sections, so that the manual patrol mode is assisted or replaced, the false alarm condition can be effectively reduced, and the reliability and the stability of the equipment are improved.

Description

technical field [0001] The invention relates to a large-resistance three-wire sleeve railway sleeper used for automatic monitoring of the train state. Background technique [0002] The sleeper is an important part of the railway track structure, which supports the rail, transmits the train load and transmits various pressures of the rail to the track bed. At present, most of the research and use of sleepers in our country are suitable for single-gauge railway lines. Sleepers are basically the same shape. However, with the continuous development of the economy, the research and use of railways will also continue to develop, and the shape and length of sleepers will also tend to be diversified according to the requirements of use. [0003] At present, the maintenance of trains and sleepers mainly relies on manual on-site inspection and maintenance. This approach has the following two problems: [0004] 1. The safety of inspectors; [0005] Second, the effect of manual ins...

Problems solved by technology

[0004] 1. The safety of inspectors;

[0005] 2. The effect of manual inspection

[0006] When the staff are faced with repetitive mechanical work, they are prone to fatigue and slackness, which reduces the effect and quality of inspections. Moreover, due to the suddenness and timeliness of equipment failures, manual inspections cannot meet the purpose of real-time monitoring, and often Disaster happened in an instant

Therefore, the effect of manual inspection is unstable, and the reliability cannot be improved.

[0007] In railway construction, there are situations where multiple gauges share one sleeper. In mixed-gauge railway lines, there are railway lines in which two gauges share one rail. The length of the sleeper also changes according to the change of the gauge. When the existing sleeper design is applied to the three-track mixed-gauge railway, the cross-sectional area of ​​the rail on the sleeper increases. In areas with large temperature differences, the rails produce The temperature force is also relatively large, the lateral resistance of the track bed is insufficient, and the entire track is more likely to lose stability
