The invention relates to an escalator with a fire-fighting function. The escalator with the fire-fighting function comprises an escalator complete machine and a fire-fighting detection device, wherein the fire-fighting detection device is composed of a fire-fighting pipeline, a spray nozzle, a smoke-sensing and temperature-sensing detector, a feedback control device, a pressure pump and a signal line, the fire-fighting pipeline and the smoke-sensing and temperature-sensing detector are laid inside a truss of the escalator complete machine, and smoke is detected by the smoke-sensing and temperature-sensing detector. When the smoke reaches a certain concentration, a signal is transmitted to the feedback control device for alarming, after the feedback control device affirms the signal, an escalator power source is automatically cut off, a smoke control and exhaust fan is linked to be started, the smoke is started to be exhausted, meanwhile, an electromagnetic valve of the spray nozzle is opened, the pressure pump is linked, and the spray nozzle sprays water to put out a fire directly. By means of the escalator with the fire-fighting function, the temperature anomaly and the smoke concentration in the escalator complete machine can be sensitively detected, meanwhile, the pressure pump is controlled to put out the fire, and the danger and the loss are reduced to the minimum.
