Elevator car door lock device and elevator

Abstract

The invention relates to an elevator car door lock device and an elevator. The elevator car door lock device comprises a belt, a door vane base, a first oscillating bar, a second oscillating bar, a horizontal crossbar, a telescopic device and a car door lock hook. The belt is connected with the first oscillating bar, and the first oscillating bar and the second oscillating bar are connected to the door knife base in a rotating mode. One end of the horizontal crossbar is connected with the car door lock hook, and the other end of the horizontal crossbar is provided with a protruding block. The protruding block abuts against one side, far from the first oscillating bar, of the second oscillating bar. The telescopic device comprises an energized magnet, a connection rod, a limit plate, a push plate and a telescopic spring, wherein the telescopic spring is arranged on the connection rod in a sleeving mode. The second oscillating bar is provided with a through hole matched with the connection rod, one end of the connection rod is connected with the limit plate, and the other end of the connection rod penetrates through the through hole and is connected with the push plate. The two ends of the telescopic spring abut against the push plate and the face, opposite to first oscillating bar, of the second oscillating bar respectively. According to the elevator car door lock device, the stroke difference between a landing door and a car door is greatly reduced, synchronicity between the landing door and the car door is improved, the length of an upper sill of the car door is greatly reduced, and an elevator well can be designed to be narrower.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car door lock device and an elevator. Background technique [0002] At present, the existing elevators rely on the car door stroke to trigger the unlocking of the car door lock and the hall door lock, such as figure 1 As shown, when the elevator reaches the leveling area, the car door 1 drives the right swing rod 3 to move left for a distance a (the distance between the hall door locking roller 4 and the right swing rod 3), and the right swing rod 3 and the hall door lock. The roller 4 is tangent, the car door 1 continues to move to the left for a distance b (horizontal stroke of the lift hook of the car door lock), the car door lock hook 6 is opened, and the car door 1 continues to move to the left for a distance c (two wheels of the floor door lock The distance between), the hall door lock moving roller 4 and the hall door lock static roller 5 stick together, and...

AI Technical Summary

Problems solved by technology

Passengers can see the inner wall of the hall door 2 in the car, which lacks aesthetics and gives the elevator user a feeling that the grade is not enough; at the same time, in order to make the hall door 2 align with the width of the entrance and exit at the end of the door opening, the width occupied by the car door 1 after it is fully opened It is 2(a+b+c) longer than the landing door, and the car door 1 needs to be equipped with a guide rail longer than the hall door 2, which requires higher force on the door guide rail, and the upper sill 7 of the car door is lengthened, which affects the layout of the shaft and during use, since the car door 1 is first opened and then unlocked, sometimes the problem that the car door lock hook 6 is stuck in the process of opening the car door 1
