The invention discloses a rotary connecting device for rail transit. The device comprises a frame, a wire feeding cylinder, a fixed wire head, a welding motor and a welding head, the wire feeding cylinder is fixedly connected to the left side of the frame, the fixed wire head is inserted into the right side wall of the frame, and the welding motor is fixedly connected to the inner wall of the frame; and the welding head is fixedly connected to the lower side of the welding motor, a rotating handle is rotatably connected to the upper end of the frame, a transmission mechanism is installed at the lower end of the rotating handle, and the outer surface of the wire feeding cylinder is sleeved with a movable wire head. When the rotary connecting device for rail transit is used, the effect of stable welding is achieved through cooperative use of structures such as a sliding block, a winding wheel and an arc-shaped baffle, the effect of sufficient shielding is achieved through cooperative useof structures such as a toothed bar, a gear and a take-up wheel, and the effect of accurate wire feeding is achieved through cooperative use of structures such as a threaded rod, a sleeve block and amovable plate.
