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

Abstract

The invention discloses a highly adaptable ballastless track track slab crack and separation automatic detection device, which belongs to the field of track slab crack and separation detection. In the process of use, a hydraulic frame structure is used to adapt to different tracks. By connecting hydraulic rods Cooperate with the linkage hydraulic rod to expand or shrink the device, thus adapting to different tracks, and a data acquisition adapter slot is set, and a high-speed camera device is installed in the data acquisition adapter slot to capture the track and The data collected by the high-speed camera device is image-fused and analyzed to detect cracks in the track plate, and then the data on both sides of the track is collected through the line-structure laser acquisition devices installed on the left and right sides, and then the track is quickly detected through system analysis .

Description

technical field [0001] The invention relates to the field of track slab crack and separation detection field, in particular to a highly adaptable ballastless track track slab crack and separation automatic detection device. 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, rigidity and comfort of ...
