Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of high-speed rail track slab maintenance, and particularly relates to a track slab cleaning vehicle and a cleaning method thereof. BACKGROUND

[0002] The ultrasonic detection method is an effective means for detecting track slabs and their lower structures. Compared with geological radar and other detection means, the ultrasonic detection method has a comparative advantage in that it can reduce the interference of the steel structure in the track slab to a certain extent. In addition, the ultrasonic detection method uses an extremely high frequency elastic wave as a seismic source, and has a higher resolution than seismic exploration and impact echo and other elastic wave or vibration testing methods.

[0003] The coupling effect of the transducer directly affects the efficiency of ultrasonic detection. Although the high-speed rail track slab is a prefabricated product, the surface is smooth when it leaves the factory, but a small amount of concrete residues, construction glue residues and silt and the like are attached to the track slab during on-site construction or operation. Similar adhesives are difficult to remove with a broom. Since the high-speed rail track slab surface is cleaned using a powerful metal scraper or a steel wire brush, the track slab is easily damaged. Usually, a shovel is used to carefully shovel along the transducer to remove the adhesives, and then a broom is used to sweep away the shoveling materials and collect them. This operation method is very low in efficiency, especially when the time available for on-line detection of the operating high-speed rail is limited, and effective means are urgently needed to assist in cleaning the track slab surface before ultrasonic detection.
