The invention relates to the technical field of rail transit evacuation mechanisms, in particular to a novel urban rail vehicle side door lifting evacuation ladder. Comprising a frame assembly, guide rail sliding block pairs and an air spring, the guide rail sliding block pairs are fixed to the two sides of the frame assembly respectively and play a guiding role in vertical sliding of the pedal assembly, one end of the air spring is hinged to the frame assembly, and the other end of the air spring is hinged to the driving mechanism. By means of the structure that the other end of the air spring is hinged to a first-stage pedal of the pedal assembly, the lifting evacuation ladder can be automatically opened and closed, operation is easy, the automation degree is high, meanwhile, the lifting evacuation ladder can be used under the emergency conditions such as power failure, and the escape evacuation capacity of a train is greatly improved.
