Problems solved by technology
[0002] At present, the landing doors installed on each building floor for use with elevators are simple purely mechanical doors. During use, operators need to manually close the landing doors. Sometimes they forget to close the landing doors, but the elevators can be used as usual. , which undoubtedly increases the danger of construction work, so it is hoped that only when the landing door is closed in place, the elevator car can run up and down normally, otherwise the elevator will be in a power-off state and cannot be used to improve safety

The invention discloses an electromechanical interlocking landing door for an elevator. The electromechanical interlocking landing door comprises a landing door frame, a sliding door body, a turning plate, a contact swing arm and a limiting switch. The sliding door body is rotationally arranged on the landing door frame and can only be opened towards the inner side of a building, the turning plate is transversely arranged on the upper edge of the opening side of the sliding door body, and when the turning plate is in a normal put-down state, the sliding door body is prevented from being opened; when the turning plate is turned upwards to the horizontal position, the sliding door body can be freely opened, a connecting base is arranged on the turning plate, one end of the contact swing arm is rotationally connected to the connecting base, the other end of the contact swing arm is provided with a roller making contact with door lock touch iron on an elevator car, and when the roller is not touched, the turning plate is locked; When the roller is touched, the turning plate can freely turn over, the limiting switch is fixed to the landing door frame, located on one side of the connecting base and linked with the turning plate, the limiting switch is in signal connection with an elevator system, and when the turning plate is in a normal put-down state, the elevator system is powered on; and when the turning plate is located at the horizontal position, the elevator system is powered off.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an electromechanical interlocking landing door for elevators. Background technique [0002] At present, the landing doors installed on each building floor for use with elevators are simple purely mechanical doors. During use, operators need to manually close the landing doors. Sometimes they forget to close the landing doors, but the elevators can be used as usual. , This undoubtedly increases the danger of construction work, so it is hoped that only when the landing door is closed in place, the elevator car can run up and down normally, otherwise the elevator will be in a power-off state and cannot be used to improve safety. Contents of the invention [0003] Based on the above problems, the object of the present invention is to provide an electromechanical interlocking landing door for an elevator, which reduces the risk of accidents caused by operators forgetting to close ...
