Problems solved by technology

The existence of the elevator sill distance will cause small carts, wheelchair rollers, high-heeled shoes, etc. to be stuck, and small items will fall through this gap to the elevator shaft and other accidents.
In order to solve this problem, the method of adding movable sills is usually adopted in the prior art, and the movable sills are opened when the elevator is leveling to fill the gaps in the sills. If this method is used, the sills will not be retracted in time when the elevator car is moving. problems, resulting in accidents

Abstract

The invention relates to a high-safety elevator door system. The high-safety elevator door system comprises a car door mechanism and a landing door mechanism, wherein the landing door mechanism comprises a landing door, a hanging plate and a lock assembly for connecting the landing door and the hanging plate, the lock assembly comprises a wedge hook arranged on the hanging plate through a mountingplate and a lock arm arranged on the landing door through a fixing plate and matched with the wedge hook, the car door mechanism comprises a car door, a door knife plate, a rotating shaft, a bottom plate and a driving motor, the bottom plate is arranged on one side, close to the landing door, of the car door, an output shaft of a driving motor arranged at the lower end of the bottom plate is connected with a rotating shaft arranged at the upper end of the bottom plate, the door knife plate is arranged around the rotating shaft and can turn over along with the rotation of the rotating shaft, and in a non-door opening state, the door knife plate is parallel to the car door. According to the elevator door system provided by the invention, the distance between a car door sill and a landing door sill of an elevator is smaller.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a high-safety elevator door system. Background technique [0002] In the overall structure of the elevator, the door system of the elevator includes the elevator hall door and the elevator car door. Usually the elevator hall door is fixed at the opening of the elevator shaft, and the car door is installed on the car. The hall door and car door of the elevator are necessary structures to prevent people and objects from falling into the hoistway or passengers and objects in the car from colliding with the hoistway. They are important safety protection facilities for the elevator and an important part of the elevator. [0003] At present, the door opening and closing structure of general elevators on the market is a form in which the door opening knife fixed on the car door hanging plate clamps the landing door lock roller fixed on the landing door, thereby driving the...
