Abstract
The utility model belongs to the technical field of lifts and provides a center opening door for a lift. The center opening door comprises two symmetrical slide rails, an upper hanging plate, a lower supporting plate, an upper door leaf, a lower door leaf and door pockets. The upper hanging plate and the lower supporting plate are arranged on the two slide rails, and the upper door leaf and the lower door leaf are arranged on the slide rails and move up and down along the slide rails. The door pockets are arranged on the slide rails along the peripheries of the two door leaves. The two ends of the upper hanging plate are respectively provided with a pulley, one end of a steel wire rope of each pulley is connected with the upper door leaf, and the other end of the steel wire rope of each pulley is connected with the lower door leaf. According to the center opening door, a rope winding structure is adopted, so the assembly is convenient; the steel wire ropes are hidden in the slide rails, so the steel wire ropes can be prevented from scratching and touching when the door is maintained or when breakdowns happen. Due to the design of the positions of the pulleys and falling-off prevention grooves of pulley covers, the phenomenon that the steel wire ropes fall off is avoided. When the center opening door is installed at a lift car door, the smooth surface of the center opening door faces towards a lift car, so objects in the lift car can be prevented from scratching and colliding when the door is opened. Through the arrangement of an arresting device on the center opening door, accidental opening of the lift car is avoided effectively in the lift running process, and the failure rate is reduced.
