The invention relates to an escalator comb plate uplifting detection device, and belongs to the technical field of escalators. When an escalator operates normally, a rear fixed plate is suffered with pressure of a compression spring, and the front end of a support is not in contact with a switch tentacle; when a foreign body is clamped by a comb plate, under the action of step operation, after the comb plate moves backwards horizontally and uplifts at the same time, a guide groove base plate abuts against the lower end of the support, after a movable support conducts anticlockwise rotation along a shaft, the switch tentacle is touched, a travel switch is triggered by the switch tentacle, and therefore the escalator stops automatically; when the comb plate resets, a rear fixed plate resets under the action of the compression spring, the travel switch resets, and the normal operation the escalator is recovered. By means of the detection device, the foreign body is clamped between the comb plate and steps, the travel switch can be triggered accurately, the escalator is stopped operating, the reaction time of the whole device is short, and the harm to a clamped object is lowered.
