The invention provides a sliding-plug door installation lifting device, and belongs to the field of railway vehicle sliding-plug door installation auxiliary supporting and lifting devices. According to the device, a sliding-plug door can be stably, reliably and accurately lifted to a designated position and an appropriate assembling inclination angle can be provided through a first-stage active lifting mechanism and a second passive lifting mechanism. The first-stage active lifting mechanism is formed by a main frame and a first-stage lifting frame together and driven by an electric winch and a movable pulley block jointly. The second passive lifting mechanism is formed by the first-stage lifting frame, a second-stage lifting frame and two steel ropes jointly. In the operation process for lifting and assembling the sliding-plug door through the sliding-plug door installation lifting device, two operators standing on the ground do not need to support the sliding-plug door with the two hands or hold the sliding-plug door with the hands to keep the sliding-plug door balanced, the operation process of the device is simple, capable of saving labor, accurate in positioning, safe and efficient, the number of operators participating in the whole process can be reduced by at least one, and the operator occupancy rate is decreased, so that the time and labor cost of the sliding-plug door installation procedures can be greatly reduced, and the production efficiency can be remarkably improved. In addition, the sliding-plug door installation lifting device has the beneficial effects of being low in cost, convenient to popularize, and the like.
