Description

Track slab cleaning vehicle

Technical Field

The utility model belongs to the technical field of maintenance of high-speed rail plates, and particularly relates to a rail plate cleaning vehicle.

Background

The ultrasonic detection method is an effective means for detecting the track plate and the lower structure thereof, and can reduce the interference of the steel bar structure in the track plate to a certain extent, so that the ultrasonic detection method has a relatively advantage compared with detection means such as geological radar; in addition, because the ultrasonic wave uses the elastic wave with extremely high frequency as the vibration source, the ultrasonic wave has higher resolution ratio compared with the elastic wave or vibration testing methods such as seismic exploration, impact echo and the like.

The coupling effect of the transducer directly influences the efficiency of ultrasonic detection, and although the high-speed rail plate is prefabricated, the surface is smooth when leaving the factory, a small amount of concrete residues, construction glue residues, silt and the like can be adhered in site construction or operation. Similar adhesive is difficult to remove by using a broom, and because the surface of the high-speed rail plate is cleaned by using a powerful metal plane or a steel wire brush, the rail plate is easy to be damaged, a scraper knife is usually manually used for carefully scraping along the moving measuring line of the transducer, and then the broom is used for sweeping and removing objects and collecting the objects. The operation mode is low in efficiency, and particularly when the time for operating the high-speed rail to perform online detection is limited, the operation mode is often passive in time, and an effective means is urgently needed for assisting in cleaning the surface of the track slab before ultrasonic detection.
