Embodiment Construction
[0017] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0018] refer to figure 2 , the present invention discloses a verification device 100 for verifying that the car door is fully closed. The door machine 10 outputs a door closing signal S1 when the door is fully closed. The verification device 100 for verifying that the car door is fully closed includes a first verification switch K3 , the car door lock switch K2, the control device 20 and the second car door close verification switch K4, the first car door close verification switch K3 and the second car door close verification switch K4 are respectively set in the car door pre-set Set position and close when the car door closes in place, the car door lock switch K2 is set at the car door lock and closes when the car door lock is locked, th...

The invention discloses a verification device and a verification method for a closed door in position of an elevator car door. A portal crane output a closed door in position signal of the portal crane when the door is closed in position. The verification device comprises an elevator door lock electric circuit for outputting a locking signal of a car door lock when the car door lock is locked, a second car door closed in position verification switch and a control device. The control device is in signal connection to the second car door closed in position verification switch, the car door locking signal and the closed door in position signal of the portal crane, separately, and judges whether the elevator car door is closed in position or not when the second car door closed in position verification switch is turned off and receives the car door locking signal and the closed door in position signal of the portal crane. By adding an independent car door closed in position verification switch contact to detect whether the car door closed in position verification switch is turned off or not and judging whether the elevator car door is closed in position or not by combining the closed door in position signal of the portal crane and the locking signal of the car door lock to prevent the condition of mis-judgment of the elevator car door closed in position when the closed door in position signal of the portal crane is short-circuited and the car door of the elevator is opened, the verification device is accurate to judge and high in safety.
Description
technical field [0001] The invention relates to the field of elevator safety, in particular to a method and device for verifying that an elevator car door is closed in place. Background technique [0002] According to the requirements of EN81-20:2014 and TSGT7007-2016, the elevator must have a bypass device for the landing door and car door, and: 1. The landing door and the car door cannot be bypassed at the same time; 2. When bypassing, only emergency electric or Maintenance operation; 3. When the bypass landing door is running, it must be verified that the car door is closed properly before bypass operation can be performed. [0003] For this, refer to figure 1 In the prior art, the door closing signal S1 of the elevator door is often used as the verification of the car door closing position (when the door machine is in place, the door machine controls the door closing switch K1 contact is closed to generate the door closing signal S1). The signal S1 is input to the elev...
