A large-resistance casing railway sleeper for automatic monitoring of train status

Abstract

The invention relates to a large-resistance three-wire sleeve railway sleeper used for automatic monitoring of the train state. It is mainly aimed at the safety of inspection personnel and the effect of manual inspection. The present invention includes a fixed sleeper, a moving sleeper and a connection assembly. The fixed sleeper includes a long rib, which is characterized in that the front end of the long rib is provided with a first convex limit block, and the rear end is provided with a second convex limit block. Block and the third convex limit block, the connecting groove formed between the second convex limit block and the third convex limit block is adapted to the first convex limit block, so A first front connecting shaft is arranged in the first convex limiting block, and a rear second connecting shaft is arranged in the second convex limiting block and the third convex limiting block. The present invention collects and compares audio files, collects real-time data, compares audio files, and analyzes problem road sections, thereby assisting or replacing manual patrol inspection, effectively reducing false positives, and improving reliability and stability of equipment.

Description

technical field [0001] The invention relates to a large-resistance sheathed railway sleeper 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 inspection. [0...

AI Technical Summary

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
