The invention discloses a lift shaft fire-extinguishing assembly. A plurality of flame sensing devices (2) are arranged on the side wall of a lift shaft (1), wherein a dry powder fire-extinguishing pipeline (3) is arranged on the side wall of the lift shaft; a plurality of automatic powder spraying devices (4) are arranged on the dry powder fire-extinguishing pipeline; a self-explosion type sealing switch is arranged on each powder spraying device; the flame sensing devices (2) are capable of monitoring the flame in the lift shaft instantly; when the flame sensing devices (2) defines that one place has flame, the switches of the automatic powder spraying devices (4) of the dry powder fire-extinguishing pipeline (3) in the corresponding area are self-exploded for injecting dry powder to extinguish fire; a remote transmission module (5) is used for sending warning information to a remote management center when the flame occurs. The lift shaft fire-extinguishing assembly is capable of monitoring the situation of the lift shaft instantly, extinguishing the fire by using dry powder in time when the fire occurs and sending the fire warning in time.
