This utility model relates to the field of coal mine equipment technology, and in particular to a safety warning device for a monorail crane locomotive. It includes a car body and a housing, with the housing fixedly connected to the inner wall of the car body. An adjustment mechanism is provided inside the housing, comprising a rotating rod, a turntable, an extraction cylinder, an extraction rod, and a connecting rod. The rotating rod is rotatably connected to the inner wall of the housing, and the turntable is fixedly connected to the side wall of the rotating rod. This utility model, through the cooperation of an electromagnet, amplifying gear, and turntable, activates an alarm system that emits a flashing light and an alarm sound in the event of an emergency. Simultaneously, it drives the extraction cylinder to spray water, causing the nozzle to rotate and spray water onto the faces of drivers of different heights and positions. This instantly stimulates the sympathetic nervous system, temporarily dispelling drowsiness and enabling the driver to react quickly and brake in time, preventing driver fatigue from causing a slow response to the alarm and potential danger.
