Problems solved by technology

[0002] In the elevator field, the elevator landing door must have a self-closing function. The common self-closing function of the landing door is mainly realized by connecting a heavy hammer with a steel wire rope. The gravity of the heavy hammer makes the elevator landing door self-closing, but the steel wire rope is a flexible connector. Easy to break, when the wire rope breaks, the self-closing function of the elevator landing door will fail, and the reliability is not high

Abstract

The invention relates to an elevator landing door device and an elevator. The elevator landing door device includes: a door upper sill, the door upper sill includes a guide rail, and a door hanging plate mechanism that moves and cooperates with the guide rail. The guide rail includes a first guide section and a second guide section. And the third guide section, the two ends of the second guide section are respectively connected with the first guide section and the third guide section; and the landing door, the landing door is connected with the door hanging plate mechanism; The guide section is closer to the side of the elevator landing door device. When the door hanging plate mechanism is in contact with the first guide section, the door hanging plate mechanism has a tendency to move towards the second guide section. The first guide section is higher than the third guide section. , the height of the second guide section decreases gradually from one end close to the first guide section to one end close to the third guide section. An elevator comprises an elevator landing door arrangement as described above.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator landing door device and an elevator. Background technique [0002] In the elevator field, the elevator landing door must have a self-closing function. The common self-closing function of the landing door is mainly realized by connecting a heavy hammer with a steel wire rope. The gravity of the heavy hammer makes the elevator landing door self-closing, but the steel wire rope is a flexible connector. It is easy to break, and when the wire rope breaks, the self-closing function of the elevator landing door will fail, and the reliability is not high. Contents of the invention [0003] Based on this, it is necessary to provide an elevator landing door device and an elevator, which can realize the self-closing function and have high reliability. [0004] Its technical scheme is as follows: [0005] An elevator landing door device, comprising: a door upper sill, the d...
