Portable flaw detection trolley for turnout flaw detection

Abstract

The present invention discloses a portable flaw detection trolley for turnout flaw detection. The trolley comprises a flaw detection trolley body, a frame is arranged on the outer wall of the flaw detection trolley body, an instrument tray mechanism is arranged on the outer surface of the upper end of the flaw detection trolley body, and an unhooking mechanism is arranged on the outer surface of the front end of the middle of the flaw detection trolley body. A probe box matrix mechanism is arranged on the outer surface of one side of the unhooking mechanism. According to the portable flaw detection trolley for turnout flaw detection, the instrument tray assembly can rotate by adjusting the rotating ring, the safety of instruments in the instrument tray assembly can be protected, the height of the probe box matrix mechanism can be conveniently adjusted through the moving gear, the adjusting assembly and the moving vertical rod, and the detection accuracy is improved. Therefore, flaw detection can be carried out on the track at different heights, the track detection accuracy of the flaw detection trolley is improved, the stability of the flaw detection trolley can be improved, and a better use prospect is brought to the flaw detection trolley.

Description

technical field [0001] The invention relates to the field of ultrasonic flaw detection of rails and the like, in particular to a portable flaw detection trolley used for flaw detection of a turnout. Background technique [0002] Due to the diversity of flaw detection surfaces of steel track turnouts, and the fact that the flaw detection parts are not easy to touch, the operating space is narrow, and there are dangers and other factors, most parts of the turnout flaw detection are currently using manual single probes, and local simple scanning devices are used for flaw detection. The coverage is small and the efficiency is very low. The trolley dedicated to the flaw detection of the turnout in the present invention is designed, and the flaw detection devices of each part are integrated on the trolley. The flaw detection devices can be quickly switched, which improves the flaw detection efficiency and detects metal materials or parts inside. For cracks or defects, commonly use...

Problems solved by technology

[0003] Existing portable flaw detection trolleys for turnout flaw detection. Currently, there is a hand-held flaw detection device for the point rail part on the market. This flaw detection device can only detect flaws on the point rail part of the turnout. Two K2.5 probes are used, and one 0 A K1 probe detects flaws on the bottom plate of the switch rail and the head of the switch rail. An operator needs to use a squatting posture for flaw detection, and an operator holds the instrument to facilitate the observation of flaw detection waveforms. Diversity, and the flaw detection parts are not easy to touch, the operating space is small, and there are various factors such as danger. At present, most parts of the turnout flaw detection use manual single probes, and some simple scanning devices are used for flaw detection. The flaw detection coverage is small and the efficiency is very low. It is not conducive to installation and portability during use, and has brought certain adverse effects to people's use process. Therefore, we propose a portable flaw detection trolley for turnout flaw detection
