Technical Field

The invention relates to the field of elevators, in particular to a synchronous door vane with a car door lock.

Background

11.2.1c) in GB7588-2003 specifies: "the horizontal distance of the inner surface of the elevator shaft from the nearest door opening edge of the car sill, car door frame or sliding door should not be greater than 0.15 m. Wherein it is further specified that: the above-mentioned spacing is not limited if the car is equipped with mechanically locked doors and can only be opened in the unlocking zone of the landing doors, except in special cases, the operation of the elevator automatically depends on the locking of the car doors, which must be verified by an electrical safety device. The general practice for the above specification is: a protective wall is added on the inner surface of a well or an independent car door lock is installed, so that when the elevator breaks down, passengers do not know a correct escape method, open the car door to escape, and then danger is caused. But the cost for installing the protective wall is high and the installation period of the elevator is prolonged; installing individual car door locks requires the installation of unlocking blades at each floor, which requires the car door lock to be installed and precisely adjusted on site when the elevator is installed. Especially when the floor is too high, the car moves from top to bottom and has a deviation, which brings more difficulty to the installation of the unlocking blade and greatly increases the failure rate of the car door lock.

With the implementation of elevator type test rules (TSGT7007-2016) and GB7588-2003+ XG1-2015, stricter requirements are imposed on the opening of the car door, and corresponding terms are added. GB7588-2003+ XG1-2015 requires the car door to be opened as follows

8.11 opening of doors

8.11.1 if for any reason the elevator is stopped in the unlocked zone (see 7.7.1), the doors should be manually opened with no more than 300N at the following positions:

a) a landing where the car is located is unlocked by a triangular key or a landing door is unlocked through a car door;

b) inside the car.

8.11.2 in order to limit the opening of the car door by the personnel in the car, measures should be provided such that:

a) when the lift car runs, the force for opening the lift car door is more than 50N; and

b) when the car is outside the area defined in 7.7.1, the car door can not be opened more than 50mm by applying 1000N of force at the door opening limiting device.

8.11.3 at least when the car stops within 9.11.5 specified distance, the car door can be opened from the landing without tools, except with a triangular key or tools permanently set on site, after the corresponding landing door is opened.

The present requirements also apply to car doors having 8.9.3-compliant car door locks.

8.11.4 for an elevator according to 11.2.1c), the doors should only be opened from within the car when the car is within the unlocking zone.

For the implementation of standard requirements, two schemes are available on the market, namely 1, adding a car door opening limiting device and 2, configuring a car door lock. For the case that the scheme 1 can only meet the requirement of 8.11.2b) in GB7588-2003+ XG1-2015 and cannot meet the requirement of 11.2.1c), the scheme 2 is the preferable scheme.
