The invention discloses a rail conveying device for remote maintenance of an end of a nuclear power steam generator. The rail conveying device comprises a supporting base, a supporting flange, a telescopic stepping motor and speed reducer, a counterweight frame, a rotatable rail, a rotary stepping motor and speed reducer, a telescopic arm, a telescopic gear, a telescopic rack and a rotary flange. The supporting base can be fixed through foundation bolts, and the supporting flange is connected with the supporting base through bolts. The telescopic stepping motor and speed reducer and the rotary stepping motor and speed reducer are installed on the two sides of the supporting flange, and the rotatable rail is supported through bearings and can rotate under the driving of the rotary stepping motor and speed reducer. The telescopic arm is installed in the rotatable rail, and the rack is installed in the telescopic arm and can stretch out and draw back under the driving of an output gear of the telescopic stepping motor and speed reducer. The counterweight frame is used for placing a control box and a power supply and has a counterweight effect at the same time.
