The invention discloses a pipe coiling mechanism for single-bolt and mechanical coil spring driven train water adding equipment. The pipe coiling mechanism comprises a reel assembly and a mechanical coil spring assembly. The reel assembly comprises two discs and a reel shaft; a water adding pipe of train water adding equipment is wound between the two discs; the mechanical coil spring assembly comprises a mounting shell, a coil spring, a ratchet wheel, a pawl and a tension spring; the coil spring is located in the mounting shell, the reel shaft penetrates through the mounting shell and is fixedly connected with the inner end of the coil spring, and the outer end of the coil spring is fixed in the mounting shell; the ratchet wheel, the pawl and the tension spring are all mounted on one side outside the mounting shell, and the ratchet wheel and the reel shaft rotate synchronously; the middle of the pawl is rotatably installed outside the installation shell through a rotating shaft of the pawl, the tension spring is connected to the outer side of the installation shell, and the other end of the tension spring is connected with one end of the pawl. The coil spring is used for accumulating elastic force when a user pulls the water adding pipe out of the reel assembly and drives the reel assembly to rotate, and the water adding pipe is automatically retracted by releasing the elastic force after the user completes water adding operation.
