A safety protection device of an escalator comprises an escalator shaft and a drive device arranged inside the escalator shaft; the drive device is connected with a stair board and a hand strap and drives the stair board and the hand strap to move; the surface of the escalator shaft is sequentially covered with a comb plate, a middle cover plate and a rear cover plate. The safety protection device is characterized in that an anti-falling net and a photo sensor cover the upper portion of the drive device; the photo sensor is electrically connected with a control system; when it is detected that light exists, electrical signals are transmitted to the control system and the drive device stops acting. The safety protection device has the beneficial effects that 1, the safety protection device has the advantages of being simple in structure, convenient to assemble, low in production cost, high in market competitiveness and the like; 2, by arrangement of the protective net, even if the cover plates fall down, the protection function is achieved, and people and the like are prevented from falling into the drive device and being injured; 3, when the cover plates are opened or gaps exist, light enters the escalator shaft and is received by the photo sensor, the drive device stops acting immediately, and the dual safety protection function is achieved.
