Ballastless track slab crack and open joint automatic detection device with high arrangement performance

Abstract

The invention discloses a ballastless track slab crack and open joint automatic detection device with high arrangement performance, and belongs to the field of track board crack and open joint detection. In the using process, a hydraulic frame structure is adopted to adapt to different tracks, and a connecting hydraulic rod and a linkage hydraulic rod are matched with each other to realize deployment or contraction of the device so as to adapt to different tracks; a data acquisition adaptation groove is arranged, a high-speed camera device is installed in the data acquisition adaptation grooveto capture the track, and the data acquired by the high-speed camera device is subjected to image fusion and analysis so that cracks of the track plate are detected, the data on the two sides of thetrack are acquired through the line structure laser acquisition devices arranged on the left side and the right side, and the track is subjected to rapid detection operation through system analysis.

Description

technical field [0001] The invention relates to the field of track slab crack and separation detection field, in particular to an automatic detection device for track slab crack and separation of a ballastless track with high configuration. Background technique [0002] The ballastless track is mainly a multi-layer composite structure composed of concrete support layer, CA mortar layer, track plate, fasteners and rails. It has good smoothness, high stability, long service life, strong durability and maintenance Features such as less work, has been widely used in track construction. However, under the action of factors such as load, temperature thermal expansion, and geological subsidence, ballastless track diseases frequently occur. Especially in the high-temperature environment in the southern region and in summer, diseases such as large-area track slab voids and joints occur continuously. Cracks and gaps in the track slab will significantly reduce the smoothness, rigidit...

AI Technical Summary

Problems solved by technology

Cracks and gaps in the track slab will significantly reduce the smoothness, rigidity and comfort of the track, and even cause the arch on the track slab to break in severe cases;

[0003] At present, the daily detection of cracks and separation gaps in ballastless track track slabs in my country mainly relies on on-site manual patrol and visual observation, lack of effective automatic detection technology and equipment, and the existing devices have a small audience, Most of them are produced by manufacturers according to the requirements of users, and there is a lack of a device that can adapt to various widths of tracks. Therefore, this application adopts a hydraulic frame structure to manufacture a ballastless track with a high degree of adaptability. The automatic seam detection device can not only adapt to a variety of tracks and adopt modular installation, but also accept user customization
