Description

Technical Field

[0001] The utility model relates to the technical field of urban rail transit detection, and more particularly to an adjustable rail inspection boom device. Background Art

[0002] Large cities have large populations and heavy traffic pressures, so subways are usually installed to alleviate ground traffic pressure. Track inspection equipment is used to test track geometry parameters. When working, it is hung on the train to perform track inspections, which is of great significance to the safe maintenance of the track.

[0003] When the track inspection equipment is working, it will be affected by the distance, angle and other data of the track. Therefore, during the test, the distance, angle and other parameters of the track should be fixed. However, in actual use, each subway line uses different vehicle models (the distance between the vehicle body and the track plane is generally 850mm-1000mm). As a result, before testing different models, the vehicle body structure needs to be re-measured and the boom tooling used to fix the track inspection equipment needs to be made. Such boom tooling has fixed size and fixed angle, so it cannot be reused on other models. In addition, the tooling itself has defects such as large size, heavy weight, inconvenient to carry, and long production cycle. If it cannot be reused, it will result in a waste of time and economic costs. Utility Model Content
