Portable steel rail moving support for carrying tunnel trolley

The utility model relates to the field of tunnel construction, in particular to a portable steel rail moving support for carrying a tunnel trolley. In order to solve the technical problems that time and labor are wasted and construction efficiency is low when a lining trolley walks on a track during tunnel construction, the lining trolley comprises a horizontally-arranged rotating shaft, the two ends of the rotating shaft are rotationally sleeved with wheels respectively, an obliquely-arranged supporting frame is fixedly connected to the rotating shaft, and an opening of the supporting frame faces upwards; the rotating shaft is fixedly connected with a vertically-arranged connecting rod, the top of the connecting rod is connected with a horizontally-arranged lifting rod, and the lifting rod is perpendicular to the connecting rod. A through hole in the front end of the lifting rod is rotationally connected with a lifting rod, and the bottom end of the lifting rod is fixedly connected with a vertically-arranged
