The invention discloses a construction hoist and floor protective door interlocking device. The device comprises an elevator frame, an elevator car and safety channels; two protective fences are arranged on the two sides of each safety channel, a protective door is arranged in each safety channel, and a magnetic lock matched with the protective door is fixed between the two protective fences; a distribution box, a distance sensor and a door opening button are arranged at the position, between the corresponding protective door and the elevator car, of each protective fence; the distance sensors are used for detecting whether the elevator car reaches corresponding floors or not; and a travel switch for detecting the opening and closing state of a car safety door is arranged in the elevator car. According to the interlocking device and method, only when the protective doors on all the floors are closed in place and the car safety door is also closed in place, the elevator can operate, and only when it is detected that the elevator car reaches a floor, the corresponding protective door can be opened, so that it is guaranteed that no person enters an elevator in the running process, and the accident that people fall from an opening of a floor is effectively avoided.

    本发明的施工升降机与楼层防护门联锁装置,包括电梯架、电梯轿厢和安全通道,安全通道的两侧设置有两防护栏,安全通道中设置有防护门,两防护栏之间固定有与防护门相配合的磁力锁;防护门与电梯轿厢之间的防护栏上设置有配电箱、距离传感器和开门按钮,距离传感器用于检测电梯轿厢是否达到相应楼层,电梯轿厢内设置有对轿厢安全门的开关状态进行检测的行程开关。本发明的联锁装置及方法,只有当所有楼层上的防护门关闭到位且轿厢安全门也关闭到位后,电梯才可运行,以及只有当检测到电梯轿厢达到该楼层后,才可开启防护门,确保了电梯运行过程中不会有人员进入,有效避免了人员从楼层开口处坠楼事故的发生。
