The invention discloses a displacement detection device for an escalator main unit. The displacement detection device is installed on the side close to a main driving chain wheel of an escalator and fixed to a fixed base of the escalator main unit. The displacement detection device comprises a connecting plate and a limit switch connected with an escalator control system through a circuit. The contact detection end of the limit switch makes contact with the escalator main unit. The other end of the limit switch is fixedly connected with the upper end of the connecting plate. The lower end of the connecting plate is fixed to the fixed base of the escalator main unit. According to the displacement detection device for the escalator main unit, the limit switch is arranged on the side close to the driving chain wheel, whether the main unit moves or not is detected through turning-on and turning-off of the limit switch, and thus operating safety of the escalator is guaranteed.
