Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle detection equipment, in particular to an abnormal sound collection device for the running gear of a rail grinding vehicle. Background Art

[0002] The primary purpose of collecting abnormal noise from the running gear of a rail grinding vehicle is to monitor and analyze the noise generated during operation, enabling timely diagnosis of equipment failures and maintenance needs. Using various sensors, we can collect abnormal noise data under different operating conditions, thereby identifying potential failure modes and changes in equipment performance.

[0003] However, existing noise collection technologies have several significant drawbacks. First, many existing devices require the vehicle to be moved during noise collection, making it impossible to collect noise in situ and limiting data acquisition. Furthermore, the inability to steer prevents comprehensive noise collection from different directions, compromising data integrity and analysis accuracy. To address these issues, we propose a device for collecting noise from the running gear of a rail grinding vehicle. Utility Model Content
