Railway vehicle wheel set ultrasonic flaw detection installation and collection module

Abstract

An ultrasonic flaw detection installation and collection module for a railway vehicle wheel set relates to the field of railway vehicle safety detection technology. In order to solve the problem that when a vehicle passes through a detection line, wheels will press down each group of ultrasonic probes in turn, and the ultrasonic probes collect signals, so that the coupling effect of the probes is poor, the installation is complicated, the maintenance is inconvenient, the detection failure rate is high, and the wear of the probes is increased. A plurality of ultrasonic flaw detection installation and collection modules are used to form a collection array, which is installed between a special railway running rail and a guard rail by using a special fixture and a base, and is distributed linearly along the steel rail. When the wheels of the railway vehicle pass through the flaw detection collection array, the wheels press through the probe pressing plates in order, the ultrasonic probes installed on the probe pressing plates perform ultrasonic flaw detection on the wheels to detect whether the wheels have circumferential and radial defects such as rims and flanges. The utility model is suitable for the field of railway vehicle safety detection technology.

Technical Field

[0002] Wheels are crucial running gear components of railway vehicles, and their quality and operational condition directly impact traffic safety. Major wheel faults include wheel tread damage, rim cracks, spoke cracks, and excessive wear on various wheel components. Currently, the primary detection method utilizes ultrasonic testing, arranging single-crystal and multi-crystal ultrasonic probes in a specific pattern. These probes work collaboratively to collect signals and diagnose faults. However, the current installation method involves mounting each ultrasonic probe as a single unit on a probe bracket supported by springs. As the vehicle passes the testing track, the wheel sequentially presses down on each group of ultrasonic probes, which then collect signals. This method suffers from problems such as poor probe coupling, cumbersome and complex installation, inconvenient maintenance, high failure rate, and increased probe wear. Utility Model Content
