Train bearing fault diagnosis device based on trackside acoustics

Abstract

The utility model discloses a train bearing fault diagnosis device based on trackside acoustics. The train bearing fault diagnosis device comprises a supporting seat; at least one acoustic signal collector; the acoustic signal collector comprises a clamping assembly which is clamped on the supporting seat; the microphone is installed on the clamping assembly and used for collecting observation acoustic signals of the bearing in the train running process. Each acoustic signal collector comprises a clamping assembly and a microphone, and the microphone is clamped on the supporting seat through the clamping assembly, so that the microphone is convenient to disassemble and assemble, that is, when the microphone needs to be maintained and replaced, the microphone can be taken down to be maintained or replaced only by separating the clamping assembly from the clamping supporting seat. 本实用新型公开了一种基于轨旁声学列车轴承故障诊断装置，包括：支撑座；至少1个声学信号采集器；所述声学信号采集器包括：夹持组件，夹持在所述支撑座上；传声器，安装于所述夹持组件，并用于采集列车行驶过程中轴承的观测声学信号。每个声学信号采集器包括夹持组件和传声器，通过夹持组件将传声器夹持在支撑座上，从而方便拆卸和安装传声器，也就是说，在需要维护、更换传声器时，只需要通过夹持组件脱离夹持支撑座则可以将传声器取下，进行维护或更换。
