Description
Technical Field
The application relates to the technical field of elevators, in particular to an integrated car door lock synchronous door vane and a door vane system.
Background
With the gradual improvement of the requirements on the safety performance of the elevator, the new GB7588 standard requires that the motor door opening mechanism needs such a function: the car door can be locked in the non-flat-floor section of the elevator, and the car door can be unlocked in the flat-floor section of the elevator under any condition, so that passengers can escape.
To achieve the above functions, the following two solutions are generally adopted:
the first is an independent car door lock which is not directly related to a door knife for opening the door and a landing door ball;
the second type is integrated in the sedan-chair lock of door sword, relies on the tight layer door croquet of clamp to judge whether flat bed, and layer door croquet is as the device that triggers sedan-chair lock unblock.
For the car door lock integrated on the door knife, the door knife is divided into an asynchronous door knife and a synchronous door knife, so that the asynchronous door knife of the integrated car door lock is different from the synchronous door knife of the integrated car door lock, and the asynchronous door knife has the risks of being unattractive and having a pulling distance exceeding the national standard because the car door is opened more greatly than a hall door, so that the car door lock integrated with the synchronous door knife is widely adopted as a feasible scheme.
The existing integrated car door lock synchronous door knife can be roughly divided into two categories, namely single-blade unlocking (a first blade and an unlocking blade) and double-blade unlocking (the first blade and a second blade can achieve the unlocking effect), the single-blade unlocking mode has higher requirements on installation, the car door and a landing door are not easy to open in an asynchronous manner in the moment of opening, the car door in a hall is synchronous and unsatisfactory, and the circle center of a landing door ball and the vertical distance of the unlocking blade need to be strictly required when the landing door is installed, otherwise, the car door can not be opened easily, and the elevator reports the fault condition.
The position of a door machine force application shaft needs to be adjusted according to door machines of different types, and corresponding door machine control parameters also need to be adjusted, so that the adaptability of the double-blade unlocking synchronous door knife is poor.
