Construction elevator door anti-collision device and anti-collision method

The invention discloses a construction elevator door anti-collision device and an anti-collision method. The anti-collision device comprises an elevator outer door which ascends and descends, an anti-collision rod located at the bottom is fixedly connected to the elevator outer door and located on the inner side of the elevator outer door, a clamping groove is further formed in the elevator body, and the anti-collision rod at the lowest stroke point is clamped and limited through the clamping groove. According to the anti-collision method, the construction elevator door anti-collision device is adopted, when the elevator outer door is opened and moves upwards, the anti-collision rod moves upwards along with the elevator outer door, when the elevator outer door is closed, the anti-collision rod moves downwards to enter the clamping groove to form limiting clamping, and the anti-collision rod at the bottom prevents a vehicle from rushing out of the door in the elevator running process.
