Description

TECHNICAL FIELD

[0001] The utility model belongs to track detection technical field, especially a track inspection detection device. BACKGROUND

[0002] Track inspection refers to the periodic or real-time inspection, monitoring and maintenance of the track in the rail transit system such as railway, subway and tram, to ensure the safety, stability of track structure and the smoothness of train operation. Since there are potential defects on the track, it is easy to cause abnormal noise during the service of the track, and then safety accidents are easy to occur, so track inspection is the core link of rail transit operation and maintenance, mainly used for finding potential defects of the track.

[0003] However, the existing track inspection device still has significant defects in practical application: insufficient wind resistance stability: when the device is working in open environment (such as viaduct, coastal area) or tunnel ventilation port and other scenes, it is easy to be disturbed by strong wind. Since most track inspection devices adopt lightweight design to reduce energy consumption, their structural rigidity is weak, and they are easy to produce lateral shaking or longitudinal jolting under the action of wind, and further produce noise. Such shaking will cause the measurement reference of the sensor (such as laser displacement sensor, high-definition camera) to deviate, and further cause detection error of track geometric parameters (such as track gauge, track direction), which may cover up the actual defects of the track or misreport abnormalities, affecting the accuracy of operation and maintenance decision.
