Four-door elevator door motor system with anti-misplacement function

Abstract

The invention relates to a four-door elevator door motor system with an anti-misplacement function. The problems that an existing elevator car door and an existing landing door are not opened in a linkage mode; opening of the landing door is easily affected by errors of the car stopping position. The four-door elevator door motor system comprises four independent car doors, a plurality of landingdoors corresponding to the car doors, a linkage locking mechanism and an anti-misplacement device, and the linkage locking mechanism comprises a linkage mechanism for achieving linkage of the car doors and the landing doors and a locking mechanism for locking the car doors and the landing doors respectively. The landing doors and the car doors are opened in a linkage mode, when the car doors are opened, synchronous opening of the landing doors is achieved through the linkage mechanism, the situation that the car doors are opened but the landing doors are not opened is avoided, linkage unlocking of the car doors and the landing doors needs to be achieved through the linkage mechanism, and the anti-misplacement device keeps a rigid static stable state all the time when the car is leveled.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a door machine system for a four-door elevator with anti-mis-movement. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line. Elevator includes car, traction system, door machine system, electric control system and safety protection system. [0003] The door machine system includes the landing door and the car door, which is the only door for passengers to enter and exit the elevator, and is also a necessary protective device for passengers to take the elevator. According to the structure of the elevator, the car door is set on the side of the car and runs up and down with the car. The car door is used to close the car and protect the passengers in the car. Landing doors ar...

AI Technical Summary

Problems solved by technology

[0006] The invention solves the problem that the existing elevator car door and landing door are not opened in linkage, and the opening of the landing door is easily affected by the error of the car's stop position, resulting in the situation that the car door is opened but the landing door is not opened. The four-door elevator door machine system, the car has four car doors, and each floor has four landing doors corresponding to the car doors. The corresponding landing doors and car doors are opened in linkage. After the car is leveled, When the car door is opened, it drives the landing door to open

[0007] The present invention also solves the defect that the existing elevator car door will be opened when the car is not leveled, and there is a certain potential safety hazard, and provides a four-door elevator door machine system with anti-misalignment. The car is equipped with Linkage locking mechanism. The linkage locking mechanism includes a leveling unlocking device. During the operation of the elevator, only the car leveling can unlock the car door, realizing the linkage opening and closing of the car door and the landing door.

[0008] The present invention also solves the defect of unfavorable rescue in the existing elevator car, and provides a four-door elevator door machine system with anti-mis-movement. By setting the linkage locking mechanism and connecting the linkage locking mechanism with the manual cable, the The car door and the landing door are opened in conjunction with the operation in the car
