Description

Technical Field

[0001] The present application relates to the technical field of skirt panel detection, and in particular to a subway skirt panel assembly consistency detection mechanism. Background Art

[0002] Subway skirt panels refer to the panels installed on the side edges of the bottom of subway vehicles. These panels are mainly used to protect the equipment at the bottom of the train from being hit and damaged by flying rocks, garbage and other track debris. In addition, by closing the space between the bottom of the train and the track, the skirt panels can improve the aerodynamic performance of the train, reduce wind resistance, and thus improve energy efficiency and driving stability. In order to ensure that each subway skirt panel can be successfully installed and applied on the subway, it is usually necessary to test each subway skirt panel.

[0003] Regarding the above-mentioned related technologies, the general detection method is to conduct a single independent measurement of the subway skirt panel. This detection method not only has low detection efficiency, for example, when detecting the flatness of the subway skirt panel, it is necessary to readjust the laser alignment instrument each time. At the same time, it is also impossible to detect the overall installation status such as the splicing accuracy and opening degree of multiple subway skirt panels after splicing.
