Train motor fault acoustic detection equipment with high detection precision

Abstract

The invention discloses train motor fault acoustic detection equipment with high detection precision. The equipment comprises a bottom plate, a platform and a cover body. A connecting block is arranged at the top end of the bottom plate, a positioning structure is arranged at the top end of the connecting block, a to-be-detected motor is mounted in the positioning structure, and a moving structure is mounted at the top end of the bottom plate. And a memory is installed at the bottom end in the cover body, a single chip microcomputer is installed in the cover body, and a sound sensor is fixed in the cover body. By arranging the moving structure, a rocking handle is rotated, the rocking handle drives a screw rod to rotate, the screw rod enables a screw sleeve to move leftwards, the screw sleeve drives a supporting plate to move leftwards through a connecting block, then a to-be-tested motor is driven to move leftwards to be in butt joint with one side of a rotating wheel, and the to-be-tested motor can be moved through left-right movement of the screw sleeve; and the detection accuracy of the motor to be detected is improved.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to an acoustic detection device for train motor faults with high detection accuracy. Background technique [0002] Before the train is in normal operation, the train motor will be tested regularly. If the motor fails suddenly, it will directly affect the power supply and cause a large safety hazard. Therefore, it is very important to regularly detect these motors, find faults early, and eliminate them in time failure, so as to ensure the smooth operation of the train; [0003] However, the existing acoustic detection equipment for train motor faults is not convenient for moving and adjusting the motor to be tested, which makes the connection between the output shaft of the motor to be tested and the runner imprecise, which affects the accuracy of detection, and there is room for improvement. Contents of the invention [0004] (1) Technical problems to be solved [0005] ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a train motor failure acoustic detection device with high detection accuracy, which is used to solve the existing inconvenience of moving and adjusting the motor to be tested, so that the output shaft of the motor to be tested is not connected accurately with the runner, which affects Defects in detection accuracy
