[0002] Railway tracks are also called rails or iron rails for short. They are mainly used for trains to travel on railways. They are usually composed of two parallel rails. Due to extreme climates in different environments, the two rails may be deformed, which may easily affect the travel of trains.

[0003] Publication No. CN116219813A discloses a detection device for railway track spacing, which slides on the upper surface and side wall of the track through a pulley and a detection wheel assembly respectively, and transmits the detection result to a controller through a signal connection between a pressure sensor and a connection end, so as to facilitate the detection of the distance between the tracks, thereby achieving the advantage of easy detection;

[0004] However, the above-mentioned detection device for rail spacing still has the following problems during actual use: the detector is driven to move and detect the spacing by a pulley installed above the rail, but due to the influence of thermal expansion and contraction in extreme weather during use, the two rails are deformed and there are differences in their spacing, height and straightness, which makes it impossible for the pulley to fully adapt during movement, which can easily cause the detection device to fall off, affecting the data of the spacing detection.
