Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to an ultrasonic guided wave damage detection device. Background Art

[0002] Railway tracks are referred to as rails for short, and are used to support the movement of trains along the direction in which the tracks are laid. Railway tracks are usually composed of two parallel steel rails, which are fixed on sleepers. The rails are I-shaped structures, and the upper end surface of the upper wing plate contacts and bears pressure with the rail wheel in the train. Under long-term extrusion and friction, they are always in a polished state; the side of the web plate in the rail and the vertical side of the upper wing plate do not contact the rail wheel, and cannot be extruded and polished. During long-term use, they are prone to rust, affecting the structural strength and stability of the rails. At the same time, there may be garbage and debris on both sides of the rails or on the rails, which may be rolled into the bottom of the train and affect the normal operation of the train.

[0003] When inspecting cracks on rails, it is usually necessary to collect images of the rails through image acquisition equipment. At this time, the staff needs to monitor them attentively. Some minor damages are not easy to be identified by the naked eye, which makes it inconvenient for operators to make judgments and decisions. Utility Model Content

[0023] In the present structure, the bottom wheel 15 can be an electric wheel, and the bottom wheel 15 can make the detection device body 1 move on the guide rail 2 to the right side of the guide rail 2. During this process, the detection plate 3 can drive the ultrasonic detector 4 to move to the right side on the guide rail 2. At this time, the cleaning plate 6 will move on the guide rail 2, and the bottom end of the cleaning plate 6 can provide a scraping effect to the guide rail 2, which can make the upper end of the guide rail 2 smoother, thereby improving the smoothness of the detection plate 3 when moving. During this process, the vacuum cleaner 10 is started. The principle of the vacuum cleaner 10 is similar to that of a household vacuum cleaner 10. There is no need to describe its power too much here. The dust suction holes on the dust box 7 can generate suction, and the impurities cleaned at the cleaning plate 6 can be sucked into the vacuum cleaner 10 through the duct 8 and the suction box 9. One side of the suction box 9 is provided with a baffle. When the suction box 9 needs to be cleaned, the baffle can be removed from the suction box 9.
