The invention relates to the technical field of railway vehicles, in particular to a railway vehicle top cover opening and closing mechanism which solves the problems that most of existing railway vehicles have no top covers or operators need to climb up the tops of railway vehicles having top covers to open or close the top covers, materials are likely to be exposed to the rain and damaged, and time and labor are wasted during operation. The railway vehicle top cover opening and closing mechanism comprises a rotary shaft and cranks, wherein the rotary shaft is controlled by a driving mechanism and penetrates through the interior of a vehicle body below a top cover, and the cranks are located on the two sides of the top cover; the two ends of the rotary shaft extend out of the two sides of the vehicle body; one end of each crank is hinged to the rotary shaft, and the other end of each crank is connected with one end of the top cover through a round pin; the other end of the top cover is provided with two top cover rolling wheels; the vehicle body is provided with rolling wheel tracks matched with the top cover rolling wheels; each rolling wheel track is formed by connecting a plurality of linear segments in an end to end mode. The operators can open and close the top cover without climbing up the vehicle top. The railway vehicle top cover opening and closing mechanism is simple in structure, good in reliability, low in cost and capable of being popularized and applied to installation of top covers of various types of railway vehicles.
