The invention relates to an overhauled-cover-plate lifting detecting device, and belongs to the technical field of escalators. A detecting device body is composed of an angular piece, a support, a travel switch and a balancing stand. When the overhauled-cover-plate lifting detecting device is used and an escalator normally runs and is covered with a cover plate, an idler wheel bears the pressure of the cover plate, the whole balancing stand is in the balanced state, and a pressing plate is not in contact with the travel switch; when the cover plate is lifted, the balancing stand clockwise rotates under the effect of the gravity of a balance weight, and the travel switch is triggered; when the cover plate is closed, the idler wheel is pressed, a balancing rod anticlockwise rotates, the travel switch is released, and the escalator normally runs. As the structure that the idler wheel and the balance weight are installed on the two sides of the balancing stand respectively is adopted, the cover plate can not be damaged when an idler wheel mechanism is additionally installed; due to an adjustable balance device adopted at the lower end, the travel switch is more sensitively triggered after the cover plate is lifted, the whole device is higher in strength, and false operation can be avoided.
