The invention relates to the technical field of fire-fighting engineering, in particular to a fire-fighting pipeline hoisting device which comprises a crane, a lifting arm arranged on the crane, a motor arranged on the crane and a winding disc connected with an output shaft of the motor, a lifting rope is wound on the winding disc, a locking device is arranged on the winding disc, and the lifting arm is arranged on the lifting arm. The locking device comprises an installation shell arranged on the crane, a ratchet wheel installed on the winding disc and a pawl matched with the ratchet wheel, the pawl and the ratchet wheel are both arranged in the installation shell, the end, away from the ratchet wheel, of the pawl is rotationally matched with the installation shell, the pawl is connected with the ratchet wheel in a clamped mode, and the ratchet wheel is connected with the ratchet wheel. And the locking device is used for locking the winding disc when the winding disc unwinds the lifting rope. The device has the effect that the phenomenon that potential safety hazards are caused to the personal safety of an operator due to the fact that the operator operates the motor by mistake and the fire-fighting pipeline descends and falls can be reduced.
