The invention discloses a supporting device. The device comprises a base, a height fine adjustment mechanism, a telescopic rod and a clamping mechanism for clamping a carrier cable. A chuck capable ofclamping a rail is arranged at the bottom of the base. The height fine adjustment mechanism comprises a double-thread screw, a first threaded pipe and a second threaded pipe. One end of the first threaded pipe is connected with the base, the other end of the first threaded pipe is in threaded connection with the lower end of the double-thread screw; one end of the second threaded pipe is in threaded connection with the upper end of the double-thread screw and the other end of the second threaded pipe is connected with the telescopic rod; and the telescopic rod is connected with the clamping mechanism. The thread directions of the two ends of the double-thread screw are opposite. The supporting device is suitable for railway lines with different structural heights, and the cantilever can be supported without the help of a rail car so that a porcelain bottle can be rapidly replaced.
