Description

Elevator door plant anticreep structure Technical Field The utility model relates to the technical field of elevators, in particular to an elevator door plate anti-drop structure. Background During elevator operation, elevator door systems play a critical role in safety. After the existing elevator is used for a long time, the door body is possibly derailed due to abrasion, looseness and other reasons between the door plate guide shoe and the sill, so that the elevator is usually required to be modified after the service life of the elevator is reached, and the safety of the elevator is enhanced. The elevator door is one of important and key reconstruction parts, the reconstruction scheme of the elevator door commonly used in the market at present is mostly to match the elevator door with the old sill by strengthening the rigidity of a door plate body or replacing an adaptive hoistway door foot, the reconstruction scheme is also various due to the fact that the existing sill in the market is quite different, when a reconstruction order is processed, the elevator door can only be processed aiming at single or single situations, the large-scale and mass production cannot be realized, and the reconstruction scheme of replacing a new hoistway door foot has the problem that the matching of the new guide hoistway door foot with the old sill cannot guarantee the anti-collision performance of the door plate.
