Synchronous door vane device with car door lock for elevator

Abstract

The invention discloses a synchronous door vane device with a car door lock for an elevator. In the specific use process of an elevator system combining the synchronous door vane device, the sequence that a car door needs to be unlocked first and then to be opened is considered, so that a reserved distance is not required between a lock tongue and a locking piece which are in a clamping state in the overall structure of the synchronous door vane device, and the door clearance in the non-leveling zone can be controlled within 10mm; and meanwhile, the car door and a landing door keep synchronous with each other in the whole opening process, and the synchronism of the car door and the landing door is relatively high. The synchronous door vane device solves the technical problem that in the practical use of an existing elevator system, the car door and the landing door are still asynchronously opened, and the synchronous effect of the car door and the landing door is not ideal, and has the advantages of being convenient to install as well as debug and the like.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a synchronous door knife device with car door locks for elevators. Background technique [0002] The widespread use of elevators has brought great convenience to people's lives. At the same time, the safety performance of elevators has also attracted increasing attention. [0003] 11.2.1 of my country's national standard GB7588-2003 stipulates: "The horizontal distance between the inner surface of the elevator shaft and the edge of the nearest door of the car sill, car door frame or sliding door should not be greater than 0.15m. If the car is equipped with mechanical locking The door can only be opened in the unlocking area of ​​the landing door. Except for special circumstances, the operation of the elevator should automatically depend on the locking of the car door, and the locking of the car door must be confirmed by an electrical safety device. Restricted". [0004] In orde...

AI Technical Summary

Problems solved by technology

[0008] But there are still two serious technical defects in the above-mentioned synchronous door knife device with car door lock for elevator, specifically: one, when the elevator combined with the above-mentioned synchronous door knife device is running in the hoistway, Once the elevator car runs to the same height as the landing door, the landing door ball is between the first blade and the unlocking blade, and the car door is opened under the drive of the door machine driving mechanism. When the door moves, the unlocking blade installed on the bottom plate of the door knife approaches the second blade under the blocking action of the door ball, and drives the unlocking transmission arm to turn against the lock plate to release the engagement state of the lock tongue and the lock, that is, After the elevator car combined with the above-mentioned synchronous door knife device runs to the same height as the landing door, the door machine driving mechanism needs to drive the car door to open first, and then the lock tongue on the door knife bottom plate will be unlocked with the locking piece on the door machine. A sufficient distance (generally more than 10mm) must be reserved between the locked tongue and the locking part, so that the car door can move first when the car door is opened again. The above-mentioned relatively large reserved distance is easy to exist. Elevator safety hazards, at the same time, in the actual use of the elevator system combined with the above-mentioned synchronous door knife device, there is still asynchronization between the car door and the landing door at the moment of opening, and the synchronization effect between the car door and the landing door is not ideal; When the elevator of the synchronous door knife device runs to the landing, only the unlocking blade on one side of the floor gate ball on the synchronous door knife device can drive the lock tongue and the lock to unlock. When installing the landing door, the floor gate ball must be strictly adjusted. The vertical distance between the center of the circle and the unlocking door knife, otherwise it is easy to cause the lock tongue and the lock piece to not be fully opened
