Embodiment Construction
[0026] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.
[0027] This embodiment is an elevator car door complete closing verification protection device, including a door opener 1 and a door opening safety control system attached to the door opener 1 . A switch assembly is set at the car door (door opening side of the elevator car), and the switch assembly is composed of a dynamic part and a static part, including a static part induction switch connected with the elevator main control board 10, and a fixed part on the car The moving door is the dynamic part induction head on the car door (the same below), and the induction head is fixed on the bottom of the car moving door, and the induction switch is arranged on the car floor 7. Generally, the induction switch is connected to the elevator main control board 10 through the car top control board 11; and the in...

The invention discloses a protection device for verifying whether an elevator car door is completely closed or not. The device comprises a door opener and a car door and is characterized in that a switch assembly is arranged at the car door part, the switch assembly is composed of a dynamic part and a static part and comprises a static part induction switch which is connected with an elevator maincontrol panel and a dynamic part sensing head which is fixed on a car moving door; and the switch assembly is positioned at the bottom end part of the car door. By means of the simple mechanism design, the complete closing situation of the elevator car door is confirmed, in addition, the conventional verification of door closing in-place carried out by electric switches of the door opener is provided, the safety protection of verification of each moving door plate closing in place is also provided, only when the two door closing verification meets the safety position, the safety and electrical control of the elevator can meet the requirements of normal operation conditions, the problem that in the closing process of the elevator car door, a door closing electric switch of the door openerverifies that the door is closed, however, the car door plate is not completely closed, then the elevator is started to operate so that man-made safety accidents can be caused is solved.
Description
technical field [0001] The invention relates to elevator control technology, in particular to an elevator car door complete closing verification protection device. Background technique [0002] With the continuous upgrading of market demand, elevator safety technical requirements are also constantly advancing. For the existing safety control, as far as the product itself is concerned, various technical standards are basically complete. It can be said that the elevator product is a product with comprehensive safety protection. However, elevator safety accidents still occur from time to time, and the reasons for individual accidents have exceeded the existing safety protection design of elevators, such as whether the elevator car door is in a fully closed state or not. The public technology is rarely involved. For example, the patent publication number CN106966279A is retrieved, which discloses a device for preventing elevator operation when the elevator landing door is not c...
