Description

Technical Field

[0001] The utility model relates to the field of busbar abnormality detection, and more specifically, to a busbar detection system and a transportation facility. Background Art

[0002] In automobile production workshops, mobile mechanisms, such as lifting platforms, are widely used to transport workpieces, such as car bodies or car interiors. Here, the busbar is a power transmission device that supplies power to the mobile mechanism. The lifting platform can be electrically connected to the busbar via a brush (also called a carbon brush) so as to draw power from the busbar and supply power to the driving device of the lifting platform in real time, thereby allowing the lifting platform to perform a shifting operation under the process of the production line, effectively meeting ergonomics.

[0003] Since the busbar is often subjected to various mechanical frictions and / or electrical thermal effects, it is easy to have abnormal temperature, which in turn causes problems such as wear, aging or breakage, thus affecting its service life and transmission efficiency. In order to ensure the normal operation of the busbar and extend its service life, the busbar should be inspected regularly after it is put into operation so that it can be replaced or repaired in time if abnormal temperature is found.

[0004] In addition, since the brush needs to slide on the busbar for a long time following the displacement of the moving mechanism, the brush is prone to abnormal temperature due to long-term wear, which is obviously undesirable.

[0005] However, the traditional busbar inspection method is to manually select random points and use a handheld temperature gun for inspection. This traditional busbar inspection method is not ideal: first, random point selection may result in missed inspections and / or false inspections; second, it is subject to the subjective influence of the inspectors and cannot achieve good results; third, due to reasons such as the brush installation method, it is impossible to simultaneously detect abnormal temperatures of the busbar and brush; fourth, the inspection efficiency and reliability are insufficient.
