Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevators, and more particularly to an elevator door system and an elevator equipped with the elevator door system. Background Technology
[0002] The elevator door system is a crucial component of an elevator. It is mainly divided into the car door system and the hall door system. The car door system is installed on the car and moves with it, its primary function being to prevent goods and passengers from falling into the shaft. The hall door system is installed on the shaft walls, serving to enclose the shaft and prevent goods and passengers on the landing from falling into the shaft. Together with the car door system, they form the only passageway into the car.
[0003] Elevator door systems typically use a horizontal sliding mechanism for opening and closing. They mainly consist of a suspension system, door panel, door pillars, and guide mechanism. The guide mechanism usually has grooves along its length to guide the door sliders and to withstand frontal impacts from the door panel. Because these grooves are directly open to pedestrian traffic, foreign objects inevitably fall into them, affecting normal door opening and closing and, in severe cases, causing elevator door malfunctions.
[0004] There are two solutions to the problems mentioned above:
[0005] The first method involves setting up a trash hole in the groove of the sill. The purpose of this method is that when the door is running, the door slider pushes foreign objects in the groove of the sill into the trash hole, and then the foreign objects fall into the shaft through the trash hole. However, this method does not fundamentally solve the problem. Since there are many electrical switches in the elevator shaft, when foreign objects, especially dust, fall into the shaft through the trash hole, they will fall onto the electrical switches, which can easily cause the electrical switches to malfunction.
[0006] The second scenario: Elevator maintenance personnel regularly clean up foreign objects from the door sills, which increases their workload and consequently raises elevator operating costs.
[0007] Therefore, existing guiding devices need further improvement.
[0008] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.
